In 2016, about 10% of total us energy consumption was from renewable energy sources (or about 102 quadrillion british thermal units (btu)—1 quadrillion is the number 1 followed by 15 zeros) about 55% of us renewable energy use is by the electric power sector for producing electricity, and about 15% of us. Due to economic progress and a rising standard of living, the demand for energy is continually increasing at present, the largest amount of energy we use is derived from conventional sources of energy which are petroleum, gasoline and coal these are non renewable sources of energy which, sooner or later, will be. The movement of wind and water, the heat and light of the sun, the carbohydrates in plants, and the warmth in the earth—all are energy sources that can supply our needs in a sustainable way a variety of methods are used to convert these renewable resources into electricity each comes with its own unique set of.
