This article explores what renewable fuels are, how they are sourced, their various types, and their environmental importance. Renewable fuels are energy sources derived from resources that naturally replenish within a human timescale. This distinguishes them from fossil fuels, which formed over millions of years and are finite.
Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals. This includes wood, sewage, and ethanol (which comes from corn or other plants).
From the late 1800s until today, fossil fuels—coal, petroleum, and natural gas—have been the primary sources of energy. Hydropower and wood were the most used renewable energy resources until the 1990s. Since then, U.S. energy consumption from biofuels, geothermal energy, solar energy, and wind energy have increased.
Energy is said to be renewable when it's sourced from renewable resources such as the sun, wind, water, or biomass. Renewable energy does not use fossil fuels, coal, or gas, but rather natural resources that can be replenished within the human lifetime.
