Energy is derived from different forms of energy. They are later converted into secondary forms such as electricity and fuels and transmitted through different channels to provide power to our homes, businesses, automobiles and lives. Energy sources are classified as renewable and non-renewable.
Renewable (or clean) energy is derived from natural resources that are constantly replenished. Examples include wind power, solar power, water power and geothermal energy. Fossil fuels (coal oil, natural gas) are regarded as non-renewable due to the fact that they form at a much slower rate than the energy we use them, which means they will eventually run out.
Solar energy can be utilized in large solar power plants or a single roof. It can also be converted into photovoltaic solar energy which produces electricity directly. Water can be harnessed in order to generate hydropower, or it can be tapped for waves and tidal energy. Geothermal power is generated by underground reservoirs that contain hot water. Bioenergy comes from many organic sources, including woody crops, dung from animals and human wastes.
Renewable energy is not just environmentally friendly learn the facts here now but also cheaper than fossil fuels. The challenge, however, is that renewable energy requires a huge infrastructure to harvest and transport energy, which can result in difficult trade-offs for environmental, social and economic reasons. However, the advancement of these technologies is continuing to increase, and they are making inroads against the more traditional fossil fuels. Renewables could even be cheaper in the long run than oil and coal.
