Electrical and Energy

Wind Turbines For The Home generally comprise a rotor (blades), generator or alternator mounted on a frame, tail, tower, grounding system, wiring and controllers, and inverters (grid-connected systems) or batteries (not connected systems). Wind turbines for your home systems generally consist of blades, a rotor, a generator or alternator mounted on a frame, a tail (usually), a tower, wiring, and "balance of system" components. Home wind energy systems are clean sources of power that uses a wind turbine to harvest the wind's energy.

Wind Energy Mutual Funds or Wind Energy ETF Exchange Traded Funds are a type of mutual funds or ETF which fall into the Alternative Energy Fund category. Air energy testing would authorize the short-term occupancy of National Forest System lands to determine the feasibility of the site to produce wind energy.

Before Investing in Alternative Energy Stocks, Know the Facts. On the surface, investing in alternative energy funds seems like a great idea, especially since it appears as though this industry will undergo record growth in the coming years.

Green electricity is electricity produced from sources which do not negatively impact upon the earth and its climate. Green electricity is constantly evolving and there are other ways of producing electrical power from green sources. Green electricity is a term describing what is thought to be environmentally friendly sources of electricity.

Wind turbines are available in a variety of sizes, and therefore power ratings. Wind turbines, mounted on a tower at 100 feet (30 meters) or more aboveground can take advantage of the faster and less turbulent wind. Different types of turbines are available for use. Wind turbines produce electricity only when the wind is blowing within the right speed range.

SEP is concerned about the costs of managing the program that are reflected in the Report. The only costs associated with marketing will be those for the travel expenses, telephone, brochures and a website. The high costs and risks of modern warfare are well known and there is a widespread perception that energy problems can best be solved through economic means, not military ones.

Fortunately, it is possible to build efficient DIY wind turbines for the home on your own. DIY home wind energy systems are much cheaper to install and can also be a lot of fun. The financial side of a home wind energy system is very sensitive to the average wind speed in the area, and to a lesser extent, the cost of purchasing electricity.

Wind energy technology can make a significant contribution to the renewable energy supply mix. Wind energy is clean, abundant, and fairly inexpensive, especially when one includes its low environmental costs. Wind energy could provide a significant percentage of our future energy demand.

Wind turbines for the home are clean sources of power that uses a wind turbine to harvest the wind's energy. The spinning turbine converts the wind's kinetic energy into electricity that can then be used in your home. In the meantime, it can be hoped that the building inspectors, zoning boards and planning boards that hear such applications will consider the over-arching objective of encouraging such systems and apply their local ordinances with a reasonable touch.

Because of growing global power consumption as well as the probable depletion using the world’s non-renewable energy source, ways of exploring and utilizing renewable power sources are being undertaken. Using alternative energy source could be both beneficial and challenging. Why don’t we explore the numerous advantages and disadvantages of alternative energy source. A substantial benefit of renewable power is it’s renewable therefore it is sustainable and can by no means go out. More to the point option power produces little or no waste material that could pollute or has harmful effects around the environment. Some countries using renewable power as the second method to obtain power will also be showing some economic benefits especially in many regional areas. The majority of their projects are situated away from the urban centres and capital cities. These folks were able to improve the use of nearby services together with tourism. Common downside of utilizing alternative power is it is hard to create big volumes of electricity comparable to that relating to conventional standard fuels. An additional prevalent problem amongst renewable power sources will be the reliability of the power supply. Since it is naturally generated, alternative power supply makes use of the next thunderstorm condition.An additional drawback or drawback to renewable energy source is that it’s comparatively more costly to create the gear necessary for producing the energy.

Listed here are the number of advantages and disadvantages of option energy source.

The sun’s rays is a superb supply of power as it’s totally free and is effective. It is feasible to maximize the energy given by sunlight to exchange conventional electricity. But you’ll find limitations, like areas at high latitude and locations with frequent rains are places unable of producing effective solar power.

Wind can be an effective electricity source. It’ll be feasible that wind power can replace as a lot as 20 percent using the total electric consumption in the foreseeable future. It’s also a really environment-safe supply of energy because there are no dangerous gases stated within the operation of converting the power. Location is a very important aspect in utilizing wind energy, high latitudes and coast lines are great locations to set up windmills. A relatively large land area is also required to set up adequate number of windmills.

Each this energy originates from water. With hydroelectric power it truly is primarily sourced from dams. Tidal energy, alternatively, utilizes natural tides using the ocean. Manufacture of power from water is an additional clean way of producing power. However there are many disadvantages. Setting up river dams as reasons for hydroelectric energy is very costly, while tidal source of power depends a lot sailing. Since oceans tend to unpredictable you are able to find only 9 locations worldwide that are suitable for this kind of energy source. And tidal energy energy vegetation is also believed to offer side effects on the migratory birds and also the fishes.

Biomass consists of fermented animal waste, agricultural crops, grains also as other natural products. It could be used to make an alcohol and also replace gasoline requirements. It maximizes waste materials alternatively power source. A drawback, it that it still produces greenhouse gas.

In recent years, energy efficiency has become a hot topic, and more and more people are looking for ways to make their homes as efficient as possible. But did you realize that one little change of a lightbulb can dramatically impact your house's energy efficiency and reduce your overall energy costs? By switching to CFL lightbulbs, or better yet LEDs, you can save a bundle.

There are basically only two reasons to install LEDs for your lighting needs, but they can be powerful motivators. These reasons are long life and energy savings. As a much more energy-efficient lighting source, LEDs can help keep your electricity costs low while still keeping the lights on.

Here's how the three main types of lightbulbs break down:

Incandescent Bulbs: Popularized by Thomas Edison, this type of lightbulb is what most people think of when the term "lightbulb" is mentioned, and most older lamps are designed to utilize this technology. However, because approximately 98% of the power consumed by an incandescent bulb is wasted as heat rather than light, these lights are extremely inefficient. Many countries have completely phased them out.

Compact Fluorescent Lightbulbs (CFLs): According to the federal Energy Star program, CFLs last up to 10 times longer than a typical incandescent lightbulb and use around 75% less energy (although they still emit 80% of the power consumed as heat rather than light). Popular because they are more efficient than traditional incandescent bulbs, CFLs do have the drawback of being around four times more expensive than a standard incandescent. However, in most applications, these fluorescent lights pay for themselves in reduced energy usage in less than six months. Each CFL bulb can eventually save consumers around $40 over the course of its life. Some environmental activists have expressed concern regarding the mercury content of CFL bulbs, although there is little-to-no health risk associated with unbroken CFL lights.

Light-Emitting Diodes (LEDs): LEDs are a type of light called a solid-state light, and they emit almost no heat when in use, making them much more efficient light sources. LED lights can last 60,000 hours or more, resulting in a standard life span of between 10 and 15 years. Compared with the already substantial useful life of a CFL, LEDs last another 10 times longer. However, LED lightbulbs are extremely expensive. Their prices have fallen dramatically in recent years, down to around $40 from $100, but that's still a lot of money to shell out for just one lightbulb. On the other hand, LED bulbs use just a fraction of the energy of incandescent lightbulbs and CFLs. For example, to get the same amount of light, you'd need a 100 watt incandescent bulb, a 26 watt CFL, or a LED of just 10-15 watts. In terms of energy used, the long-term savings is extraordinary.

The short of it is that LED lights are expensive up front, but with a life span of more than a decade and decreased energy usage of up to 90% over a standard incandescent lightbulb (100 watt), you will enjoy extensive savings over time.

Until recently, you only had one option when it came to installing LED lighting: replacing all your light fixtures with models specifically designed to work with LED lights. Because the vast majority of all LED lightbulbs featured a pin, or "plug-in," base, they could only work with specialty LED lights. However, current attitudes toward energy efficiency have motivated the development of LED bulbs that can fit into traditional light fixtures. That means that upgrading to energy-saving LED lighting for your home is as simple as purchasing LED bulbs equipped with standard screw-in bases. Available in a variety of shapes and sizes ranging from small reading lamps to flood lights, LED lighting now works with many existing light fixtures.

If you're still interested in switching out some of your old light fixtures to better suit your current needs or to accommodate plug-in LED bulbs, an electrician in your local area should be able to provide assistance. Not all residential electricians provide LED lighting upgrades, so make sure that the electrical contractor you hire is qualified to handle the project.

The most common unit of measurement on the electricity meter is the kilowatt hour (KWh), which is equal to the amount of energy used by a load of one kilowatt over a period of one hour, or 3,600,000 joules. Some electricity companies use the SI megajoule instead.

Demand is normally measured in watts, but averaged over a period, most often a quarter or half hour.

Reactive power is measured in "thousands of volt-ampere reactive-hours", (kvarh). By convention, a "lagging" or inductive load, such as a motor, will have positive reactive power. A "leading", or capacitive load, will have negative reactive power.

Volt-amperes measures all power passed through a distribution network, including reactive and actual. This is equal to the product of root-mean-square volts and amperes.

Distortion of the electric current by loads is measured in several ways. Power factor is the ratio of resistive (or real power) to volt-amperes. A capacitive load has a leading power factor, and an inductive load has a lagging power factor. A purely resistive load (such as a filament lamp, heater or kettle) exhibits a power factor of 1. Current harmonics are a measure of distortion of the wave form. For example, electronic loads such as computer power supplies draw their current at the voltage peak to fill their internal storage elements. This can lead to a significant voltage drop near the supply voltage peak which shows as a flattening of the voltage waveform. This flattening causes odd harmonics which are not permissible if they exceed specific limits, as they are not only wasteful, but may interfere with the operation of other equipment.

In addition to metering based on the amount of energy used, other types of metering are available.

Meters which measured the amount of charge (coulombs) used, known as ampere-hour meters, were used in the early days of electrification. These were dependent upon the supply voltage remaining constant for accurate measurement of energy usage, which was not a likely circumstance with most supplies.

Some meters measured only the length of time for which charge flowed, with no measurement of the magnitude of voltage or current being made. These were only suited for constant-load applications. Neither type is likely to be used today.

1 - Voltage coil - many turns of fine wire encased in plastic, connected in parallel with load.

2 - Current coil - three turns of thick wire, connected in series with load.

3 - Stator - concentrates and confines magnetic field.

4 - Aluminum rotor disc.

5 - rotor brake magnets.

6 - spindle with worm gear.

7 - display dials - note that the 1/10, 10 and 1000 dials rotate clockwise while the 1, 100 and 10000 dials rotate counter-clockwise.

Electricity meters operate by continuously measuring the instantaneous voltage (volts) and current (amperes) and finding the product of these to give instantaneous electrical power (watts) which is then integrated against time to give energy used (joules, kilowatt-hours etc.). Meters for smaller services (such as small residential customers) can be connected directly in-line between source and customer. For larger loads, more than about 200 ampere of load, current transformers are used, so that the meter can be located other than in line with the service conductors. The meters fall into two basic categories, electromechanical and electronic.

The most common type of electricity meter is the electromechanical induction watt-hour meter.

The electromechanical induction meter operates by counting the revolutions of an aluminium disc which is made to rotate at a speed proportional to the power. The number of revolutions is thus proportional to the energy usage. It consumes a small amount of power, typically around 2 watts.

The metallic disc is acted upon by two coils. One coil is connected in such a way that it produces a magnetic flux in proportion to the voltage and the other produces a magnetic flux in proportion to the current. The field of the voltage coil is delayed by 90 degrees using a lag coil. This produces eddy currents in the disc and the effect is such that a force is exerted on the disc in proportion to the product of the instantaneous current and voltage. A permanent magnet exerts an opposing force proportional to the speed of rotation of the disc. The equilibrium between these two opposing forces results in the disc rotating at a speed proportional to the power being used. The disc drives a register mechanism which integrates the speed of the disc over time by counting revolutions, much like the odometer in a car, in order to render a measurement of the total energy used over a period of time.

The type of meter described above is used on a single-phase AC supply. Different phase configurations use additional voltage and current coils.

The aluminum disc is supported by a spindle which has a worm gear which drives the register. The register is a series of dials which record the amount of energy used. The dials may be of the cyclometer type, an odometer-like display that is easy to read where for each dial a single digit is shown through a window in the face of the meter, or of the pointer type where a pointer indicates each digit. With the dial pointer type, adjacent pointers generally rotate in opposite directions due to the gearing mechanism.

The amount of energy represented by one revolution of the disc is denoted by the symbol Kh which is given in units of watt-hours per revolution.  Using the value of Kh, one can determine their power consumption at any given time by timing the disc with a stopwatch. If the time in seconds taken by the disc to complete one revolution is t, then the power in watts is:

For example, if Kh = 7.2, and one revolution took place in 14.4 seconds, the power is 1800 watts. This method can be used to determine the power consumption of household devices by switching them on one by one.

Most domestic electricity meters must be read manually, whether by a representative of the power company or by the customer. Where the customer reads the meter, the reading may be supplied to the power company by telephone, post or over the internet. The electricity company will normally require a visit by a company representative at least annually in order to verify customer-supplied readings and to make a basic safety check of the meter.

In an induction type meter, creep is a phenomenon that can adversely affect accuracy, that occurs when the meter disc rotates continuously with potential applied and the load terminals open circuited. A test for error due to creep is called a creep test. 

Electronic meters display the energy used on an LCD or LED display, and can also transmit readings to remote places. In addition to measuring energy used, electronic meters can also record other parameters of the load and supply such as maximum demand, power factor and reactive power used etc. They can also support time-of-day billing, for example, recording the amount of energy used during on-peak and off-peak hours.

Some Country need of lowering its greenhouse gas emissions. Its government has been organizing programs to help decrease energy wastage and production of fossil fuels. If every household in the country would keep their power consumption to a minimum, it would be a great help in achieving energy efficiency targets. This is why the government has started the use of smart meters, which can significantly help in a widespread application of practical energy efficiency measures.

These modern meters, in comparison to the traditional meters, are not read manually. They are built with a wireless communication device so that the periodic reading can be easily read by the consumer without having to wait for the any power company personnel to read his house's electricity meter. They don't only lessen the frequency of having to issue the usual electricity bills, but will also make it possible to connect and disconnect electricity remotely when you transfer to a new home or when you switch your electricity supplier. The power company doesn't need to drop by house to do these things.

More importantly, this new metering device would enable consumers to read their latest meter readings. Smart meters record data about your power consumption every 30 minutes and help you compare your usage in a day. You can then decide from there at what time during the day can you still be able to save on energy, with what appliances, etc. You can also choose the supplier that will work for you best, particularly those that offer power pricing schemes that vary according to the time of day.

If you use this metering device, you can also determine the practical energy efficiency measures you need to focus on at home to have the most savings on energy and money. The government and energy suppliers are promoting different ways to become more energy efficient.

Among the most emphasized is the use of cooling and heating systems. Energy companies suggest that you set rules so you'll keep the cooling and heating system usage to a minimum. Others may decide to use the heater only when the temperature drops to 10 deg C or lower, instead of 12 deg C. For cooling systems, consumers might want to try putting up the temperature by 1 deg C. For those who use smart meters, they can plan the use of their heater according to their recorded consumption.

A metering device with wireless communication capability gives consumers all the important information about how and when power is used. It can definitely help households know more about their electricity consumption, make the necessary decisions and actions towards energy efficiency, and ultimately help in lessening greenhouse gas emissions.

Renewable energy is energy that is obtained from natural sources--such as the sun and wind--and can be replenished or renewed naturally. Since renewable energy can usually be obtained without doing significant harm to the environment, people have been developing many ways to utilize it efficiently. While the use of renewable energy is not a recent phenomenon, investment in these technologies has grown in recent years as a response to the rising prices of fossil fuel and the effects of global climate change. Here are the five primary types of renewable energy sources:

• Wind energy 

Strong winds are capable of running wind turbines which are used in some areas to produce electricity. Normally these can be seen along shorelines, especially in areas where the wind is especially strong. Wind energy is a clean energy that can be utilized as long as the wind continues to blow.

• Water energy 

Strong currents of water are also capable of producing electric power. Areas where there are big waterfalls are at an advantage since waterfall currents are extremely strong and can help supply a portion of a city's electrical needs. Water energy is divided into different forms. These are: ocean energy, hydroelectric energy, kinetic energy from damless hydro, and hydroelectric power from micro-hydro systems.

• Solar energy 

Solar energy is obtained from sunlight. This technology relies on solar panels that collect sunlight and turn it into voltage which is then stored in a battery for future use. A group of solar panels is called a photovoltaic array and many homeowners are now installing their own arrays at home to supplement or satisfy their energy needs. Solar energy can also be used to power individual items, such as lights and portable generators.

• Biomass energy 

This energy is derived from industrial factories that process wood and agricultural products. It is a natural product from the synthesis of trees and other plants. While carbon dioxide emissions are produced through biomass, the amount is lower than that from the burning of fossil fuels. In addition, biomass cuts back on the need to produce new landfills as significant amounts of waste are consumed in the biomass process.

• Geothermal energy 

Geothermal is obtained from deep in the Earth's crust. Radioactive particles inside the Earth are constantly decaying, producing an energy that we can exploit for our own usage. While it's not always easy to utilize this form of energy, once a geothermal power station is up and running it provides a source of clean, reliable energy with minimal effects to the environment.

Although not all of these technologies have been utilized to their full potential yet, it is expected that investment in alternative energy sources will continue to increase in the coming years. It is likely a combination of these technologies that will help lead us to a cleaner energy future.

Green energy means generating energy from sources that emits as little as or no pollution at all. Whenever we burn fossil fuels like coal and petroleum, we are emitting too much carbon. But whenever we harness the sun, wind, or waves energy, there are minimal or no pollution at all.

For this article, we'll be discussing Wave Power.

Waves, as powerful as they are, are caused by the wind blowing over the surface of the ocean. Many would have loved to go surfing because of the gigantic waves of Hawaii or the Caribbean. These powerful forces have contributed greatly in the name of sporting, fishing and traveling. But with recent breakthrough, waves are now being considered as one of the green and renewable energies.

Waves sometimes vary in their intensity, but there some points in our world where the wind blows in a consistent force thus making the waves come in consistent intensity as well. In all areas of harnessing renewable energy, the more consistent the sources are, the better we can harness continuous energy source.

We've identified the desire and the need to harness the energy from the waves. The next question to discuss is: "where shall we harness it?" Well, as most of us know that the strongest waves comes not from the shoreline, but quite further. It's in a place where there are lesser sands, sandbars and other obstacle to block their forces, and that is in the deep waters. Waves need momentum to build and by not having any obstacles in their paths, it will be easy to gain momentum in the deep waters.

The problem now is how to create a machine that can harness wave power in deep waters. You might ask: has this been done before and how successful has it been? Well, the concept is a little bit hard to explain, but in simpler terms, the machine will be in a form a buoy so that it will bob above the water. The buoys are elongated in shape and are made up of connected sections that will flex and bend as it moves along the waves. And as these buoys flex and bend, this motion will be pumping high-pressured hydraulic oil into the hydraulic motor that will then drive the electrical generators.

The possibility of harnessing renewable energy is endless and limitless. The only thing that can hold us back is our imagination and physical capabilities! However, in one way or another, we're catching up and we're now seeing the possibility of using renewable energy. We'll just have to hope that soon, our technologies will be able to make these feasible.

The main problem in using solar energy to power a home is that solar panels cost is unfortunately prohibitive. The power cost to run a home depends on a number of factors such as the amount of power a household consumes, the amount of sun the property receives, whether the panels are new or used, government rebates available, and so on. These variables contribute to the overall cost of panels to harness the sunlight and generate free energy. By using some tips, you can cut the energy cost in half.

With the right knowledge, a few simple tools found at your local hardware store and a kick of your enthusiasm, you can build your very own panels to power your home. Sadly, many people get stuck talking about the beauty of panels and not taking action to enjoy them. Solar power kits are now available in the market and these are often less expensive than buying each individual component. If you are enough driven to save significant amount money, you can build and install your own panels in a single weekend for less than $200. You can basically power up any appliance you have in your home.

Go for a reputable manufacturer that offers a long warranty period on the panels. When you are substantially offered at least 25 years of service contract, you can expect your system to last long for at least 25 years. The amount of time you are covered by the warranty should be long enough to pay for the panels and make you a profit. Warranty gives a worthwhile investment of solar panels cost for free electricity.

You can take advantage of government tax incentives and rebates upon the installation of your solar energy technology. Also, determine if your local government offers any kind of solar program. There are solar loans financed by some cities to enable residents to pay back the loans for the panels. However, if you plan to take up a loan to pay for the entire system, make sure that you also take into consideration the interest that is attributed to the amount of loan. If you are hiring a professional installer, he may walk you through all applicable programs to help you save the most.

Used panels are always cheaper than new ones. If you are not willing to pay for new panels you can find folks selling their used panels at considerably cheaper prices. However, there are some crucial things that must be taken into high consideration. The "ideal" used panel should be in good shape and should look almost new. The glass should be clear, dry, intact and with no cracks or holes. Perhaps the most important consideration is the energy output of the used panel. Take a voltmeter and test the circuit of each panel before you close a deal. The best source of second-hand panels will be the one that is close enough to your location for easy visits and accessible panel inspection.

High quality panels with high efficiency should not always be priced at a premium. Follow the aforementioned tips to enjoy a favorable solar panels cost for free energy.

There is a growing apprehension about the looming energy crisis. Every government in the world is looking for ways to lessen dependence on fossil fuel and has shifted focus to alternative energy sources. Concerned groups and individuals have joined global efforts in increasing public awareness about the need to conserve energy and preserve natural resources.

So what has led to this energy crisis? There is no one answer because the cause is a series of misuse and abuse of the Earth's resources. And the problem does not stop with the lack of energy. Rather, it permeates all aspects of planetary life.

To meet the growing needs of the ever-increasing population, plants and industries had to be built. However, modernization of industries demand exceedingly large amounts of energy while the Earth's traditional sources of energy, coal and oil, are dwindling. Compounding the situation is the non-stop emission of toxic gases by factories and even by man himself in his ordinary daily activities. Those gases pollute the air and contribute to global warming, making the planet unsafe for man to live in.

Actually, energy crisis is just a component of the global problem of a sick and perhaps dying planet. Nonetheless, the solutions to the energy crisis, specifically the use of renewable energy sources, can check the further degradation of the planet which, coupled with the efforts to restore many of the natural resources that will hopefully nurse the planet back to health, can give us all a brighter future.

Here are some ways the use of alternative energy sources can avert energy crisis and help in the wellness efforts for Mother Earth:

Present supply from renewable energy sources contribute about 18% of global energy consumption. What many independent groups are proposing is 100% supply of energy coming from alternative sources, meaning fossil fuels and nuclear power will not be used. And this is very much possible considering the long-term potentials of the renewable energy from sunlight, wind, water, tides, and geothermal heat. Some scientists are already proving that their respective countries can soon power themselves completely by renewable energy.

A major benefit to using alternative energy sources is the reduction in carbon dioxide emissions and many other pollutants. Solar energy panels and wind turbines do not have any emissions. This not only provides clean air for humans to breathe but also stops any additional contributory load to global warming.

The technologies used in harnessing renewable energy create very little waste materials. In fact, there is even a renewable energy source, biomass, which makes use of waste products in generating power. This is a two-faced solution that responds to the problems of energy supply and waste disposal.

Less dependence on fossil fuels also means there would be less need to strip-mine wide areas for coal and oil sands. There will no longer be oil spills that pollute the seas and kill birds and marine life.

As viable as alternative energy sources are, it would still take some time before the world can be weaned from dependence on fossil fuels. For the time being, while the infrastructures for renewable energy sources are being built, the most that we can do to help forestall the energy crisis is to reduce the total requirements for energy.

Wind power is just one of nature's wonders, handed to mankind, just waiting to be harnessed and converted into free clean energy. Renewable due to its never ending supply, cost effective to our earth by decreasing carbon emissions and faithful in its reliability.

Wind has been used for thousands of years to energize sailing ships, water pumps and grinding of grain. Interest in Wind Power as an alternate form of sustained energy has only recently gained the world's attention. Always skeptical and slow to change, governments are dragging their heels, instead of backing this "free" energy source which is globally available with constant supply.

Farms using Wind Power, although costly with initial installation have been proven worldwide to be one of the best natural ways to produce clean energy. Recuperating costs will be achieved by selling off stored energy surplus, thus extending the benefits to more than one consumer. Wind Powered Farms cover large areas and can spoil the aesthetic view to the beholder, but with their turbines placed so high their ground footprint is minimal and look beautiful compared to a nuclear reactor plant. They are not truly carbon emission free as their turbines do emit some carbon waste, but in comparison with other sources of energy, this is insubstantial. Domestic Wind Powered Turbines are also readily available and working in conjunction with solar energy will generate enough electricity to maintain households.

Our supply of fossil fuel will eventually be exhausted, but this should not be the reason to seek out other energy sources. However, the carnal waste from fossil fuel has already threatened earth's future, so therefore the adoption of clean, renewable forms of energy such as Wind Power is crucial to all inhabitants of our planet.

We must find other sources for alternative energy if the planet is to survive. It is just a matter of time before the planet gives us no choice in the matter of free energy as there will not be anything else to use. Everyone in the world must contribute to finding an answer to what we can use in place of fossil fuels to help our planet.

It is a race to see who finds the answers to the world's energy crisis. Wind Power just might provide environmental and economic benefits for the United States. It offers a clean source of alternative energy for everyone. Many people are not only using wind power for their homes but some are actually farming and have huge Wind Power Ranches to help provide communities with power.

Perhaps the first question to be answered is - what is an Energy Performance Certificate? The quick answer is that the certificate will tell you exactly what the energy performance of your home is, and will give you recommendations on making your home more energy efficient. Under the Housing Act 2004 all homes being sold or rented in the UK must have an Energy Performance Certificate. Originally this was part of the notorious Home Information Packs, but in July 2010 the government suspended HIPs, retaining the EPC's - probably because they're a good idea.

If you are thinking of selling a home then you must provide one of the certificates for any interested buyers to see. It's easy to get a certificate as you just need to contact an accredited domestic energy assessor who is a fully trained to carry out the survey to the correct standard. You can either contact your estate agent for their recommendations on who to use, or you can search online using the Energy Performance Certificate Register website which is run by a company called Landmark on behalf of the government. Your local phone book may also have the details of accredited domestic energy assessors.

The current cost of a certificate is approximately $100 for an average sized house and will take about a week to complete. You need to commission your certificate before your property goes on the market. Once you have the certificate it is valid for 10 years.

The certificate shows two different levels of ratings, one that applies to the energy usage of your home, and one, which applies to the carbon dioxide emissions. A higher rating indicates a more energy efficient home. It is presented in very easy to read tables which show you the current rating and the potential rating, and the potential savings that could be made if you choose to follow the recommended measures.

The rating of your home is graded from A to G, with A being the most efficient. An average home will generally receive an E grading. The same calculations are applied to all properties so it's easy to compare the energy efficiency of different homes. The calculations are based on standardised assumptions of occupancy, heating and geographical location.

The certificate takes into account specific elements such as whether you have cavity wall insulation, whether the loft is insulated, whether windows are double glazed and how the home is heated. It also takes into account the source of hot water and lighting efficiency.

Your certificate will include a section showing recommendations for improving the energy rating. Some of the suggestions may cost less than $500 to implement while others will cost more. The recommendations show the estimated savings per year, as well as the improved energy efficiency rating.

Examples of recommendations include:

· Cavity wall insulation - this fills in the gaps between the inner and outer layers of your external walls with integrating material which reduces heat loss. It is a simple process as small holes drilled into the outer walls so that insulation material can be pumped in by a professional company. After the walls have been filled the holes can be made good. The beauty of doing this is that you will get nice certificates of guarantee for the work which may help you sell your home.

· Low energy lighting - this is a really easy one to do as you simply need to replace your ordinary bulbs with low energy bulbs if you haven't already done so.

· Loft insulation - this is a measure that most people could competently do themselves.

· Fitting a condensing boiler - condensing boilers are much more efficient than other types of boilers but can be quite expensive to fit so you may only want to consider this measure when your existing boiler needs replacing. These boilers also need a drain so this may be worth considering if you are intending to remodel your kitchen.

· Fitting double glazing - double glazing can significantly improve energy efficiency by reducing drafts around windows. They also provide better security and less chance of condensation forming, but are quite expensive to fit.

There is a government run website where you can enter your Energy Performance Certificate number to have access to an online tool for making your home more energy efficient. This website will give you an instant report that you are able to change according to your plans for your home. For instance if you are intending to add cavity wall insulation then it will show you how much money you might save heating your home. It allows you to play around with lots of different combinations to see which will save you the most money and which is the most energy efficient to do.

People are becoming more conscious of the need to reduce their carbon emissions, and many are also conscious of the rising costs of heating a home. Implementing some of the measures highlighted by a certificate can potentially save a homeowner a lot of money, which may give them that warm fuzzy feeling that comes from living in a cosy home that is affordable to heat, made all the sweeter by knowing they are reducing their carbon footprint.

These certificates are definitely something for buyers to bear in mind when viewing properties as they show the projected costs of heating and lighting a home. A property that scores more highly may prove to be more desirable than a similar property scoring lower, with higher cost recommendations. An Energy Performance Certificate can be viewed as a positive measure, which can show us how to save money and the environment.

How do I get an Energy Performance Certificate? It's easy to obtain, and in the great scheme of things its costs are relatively low, your resource for selling it yourself. Buying a home with an up to date EPC enables the new owners to plan improvements that will be cost efficient, which has to be a good thing.

Having an Energy Performance Certificate (EPC) is a compulsory part of the Government's Home Information Pack (HIP) scheme which is now obligatory for most homes on the market in England and Wales. The EPC displays the energy efficiency and environmental impact of your home through a number of coloured bar charts that you may have seen on a number of different white goods and appliances.

The first graph chart grades energy efficiency with a green bar at the top meaning 'A' which is 'Very Energy Efficient' to a longer red bar down at the bottom meaning 'G' which is 'Not Energy Efficient'. There is also the Environmental Impact Chart which shows CO2 emissions of the home in blue and grey bars. An EPC will also include and assessor's recommendations and any suggestions and advice on how to improve the ratings of a building.

All new build properties now require an EPC and any older property that is being sold will also need one as part of their HIP. Without this, you won't be allowed to put your home on the market! In order to get an EPC as part of your HIP pack or in order to let a property the only way to do so is through contacting a Domestic Energy Assessor. Assessor's aren't particularly hard to find now that EPCs are so common, there will be plenty listed online and in the Yellow Pages and an assessment will only cost in the region of £100 an average house. 

Your EPC will be valid for up to ten years but if it's being used as part of a Home Information Pack it must have been conducted within the last 3 years.

During the inspection, the Domestic Energy Assessor will look into every energy related area of your home. They'll discuss energy usage in your home with you and any steps towards being more energy efficient that you're already taking. 

For example, they may ask and advise about double glazing installed, ask you about using energy efficient light bulbs or what standards of insulation you currently have in your home. Domestic Energy Advisor's aren't there to interrogate you and listening to them wont only help you help the environment but also help you save money as well.

Energy Performance Certificates (EPC) are the Governments way of complying with European Legislation in respect to the energy efficiency of buildings laid out in the European Performance of Building Directive (EPBD). 

The purpose of an EPC is to assess and record the energy efficiency of a property. Completed EPC's provide a rating of the energy efficiency and CO2 emissions of a building from A to G - where A is a very high efficiency rating and G very poor.

As EPC's are produced using standardised methods, the energy efficiency of one building can be directly compared to another building of the same type. This helps potential property buyers or tenants to compare the energy efficiency of one property with another so that they can consider energy efficiency and fuel costs as part of their investment.

An EPC features an easy-to-understand graphical representation of the efficiency of the property and also deeper information providing recommendations on what can be done to improve the energy rating. There is also, usefully, an estimation of the energy rating that could be achieved if all the recommendations are carried out.

As a property owner or a landlord and particularly for anyone with a passion for minimising waste and saving the environment, an EPC holds great value. Fuel costs have increased significantly over the past few years and this has prompted many home owners to try and make their property more energy efficient. A property that has a high rating of energy efficiency becomes more attractive to a potential buyer or tenant, thereby raising the marketability and expected value the property may achieve.

But the importance of an EPC is not just one of fuel cost saving and environmental friendliness. From a legal perspective, as of the 21st May 2010 it has been made a requirement for anyone selling or renting a property in England or Wales to order an Energy Performance Certificate before the marketing of the property commences. It is the property owners sole responsibility - not the selling or letting agents. The EPC must be made available to potential buyers or tenants at the earliest opportunity and certainly before any contractual agreement is reached. In fact, if an EPC is available it should be provided whenever the property is viewed by a potential buyer or tenant. Failure to meet the requirements in respect to EPC's will result in a fine - which can be repeatable for every day a breach is continued.

In conclusion, an EPC should be viewed as an affordable and highly useful assessment of the energy efficiency of your property. It contains actionable recommendations which will help increase your properties efficiency, which will of course help cut your fuel bills saving you money in the short term, and also help the marketability of your property should you ever wish to sell or rent. There are many registered Domestic Energy Assessors (DEA) who will visit your property and produce an EPC at relatively low cost. It is recommended to have your property assessed right away so that you can start to feel the benefits, rather than waiting until you may wish to sell or rent it out. Remember the real reasons for EPC's and don't just get one because you have to.
