Electrical and Energy

Electricity is the most commonly used form of energy and is very essential to people. At present, there are lots of electrical appliances and devices that help people's lives so comfortable and convenient. All of electrical appliances, equipments and gadgets are powered by electricity. Electricity is so important in residential, commercial and industrial structures due to the reason that electricity can be used for illumination, production and many other applications.

There are lots of sources of electricity and the energy resources fall into two main categories namely the renewable source of energy and the non-renewable source of energy. Under the category of renewable source of energy, the commonly used sources are sun, water and wind. While on the non-renewable energy, it can be divided into main types namely fossil fuels and nuclear fossils.

However, due to the issues concerning about the earth's natural sources, the alternative sources to produce electric power is gaining attention from consumers. As people continue to burn gas, oil, coal and earth's rainforest, people are contributing to the increase of global warming. The continuous use of fossil fuels lead to its reduction of supply which is becoming an issue due to the reason that is has reached critical stages. This is why something needs to be done as soon as possible before these non-renewable sources of energy run out.

There are many people who choose to use the renewable source of energy to generate electric power. The materials used for alternative electric energy have already existed and these devices where being modernized and operated with the use of the latest technology. These devices are used in order to produce solar power, wind power and hydropower. These are renewable sources of electricity meaning these sources are pure natural, constant, free and abundant.

Wind power is an alternative electric energy that uses windmills, wind turbine and sails in order to generate electricity. Windmills caught wind in its huge blades causing them to turn. The rotating action turned a shaft and the shaft will turn the millstones. However, today's windmills are now connected to turbines to generate electricity. Another alternative electric energy is the hydropower. Hydropower is generated from water which is being used to turn a wheel connected to a mill. Nowadays, the force of water released from a dam to turn the blades of the turbine connected to a generator produces electricity. And the very popular alternative electric energy is the solar power. Solar energy is an energy derived from the sun and converted into heat or electricity.
