There are many different ways in which the abundance of energy around us can be stored, converted, and amplified for our use. To help understand the key energy sources that will play an important role in the world’s future, it is required to familiarize with some of the history, theory, economics, and problems of the various types of energy.
The energy sources have been split into three categories: fossil fuels, renewable sources, and nuclear sources. The fossil fuels here are coal, petroleum, and natural gas. The renewable energy sources are solar, wind, hydroelectric, biomass, and geothermal power. The nuclear-powered sources are fission and fusion.
