Energy is derived from different forms of energy. They are later converted into secondary forms like fuels and electricity, and then transmitted through different channels to provide electricity for our homes industries, vehicles and lives. Energy sources find out this here can be classified as renewable or non-renewable.
Renewable (or clean) energy is generated from natural resources that are constantly replenished. Examples include wind, solar and geothermal. Fossil Fuels (coal oil and natural gas), are non-renewable, because they form much more slowly than we do.
Solar energy can be utilized in large solar power plants or on one roof. Solar energy can be converted into photovoltaic energy that generates electricity directly. Water can be used for the production of hydropower, or to generate wave and tide energy. Geothermal power is derived by underground reservoirs that contain hot waters. Bioenergy is derived from various organic sources, including woody crops, dung from livestock and human wastes.
Renewable energy is not just green, but also less expensive than fossil fuels. The problem is that renewable energy requires a huge infrastructure to harvest and transport the energy, which can result in difficult trade-offs in terms of economic, social and environmental reasons. The advancement of these technologies is continuing to expand and they are progressing against the more conventional fuels. In the long term renewable energy could be more cost-effective than coal and oil.
