Answer 1

Answer:

Renewable energy is energy from sources that are naturally replenishing but flow-limited; renewable resources are virtually inexhaustible in duration but limited in the amount of energy that is available per unit of time.

The major types of renewable energy sources are:

Explanation:

Until the mid-1800s, wood was the source of nearly all of the nation's energy needs for heating, cooking, and lighting. From the late 1800s until today, fossil fuels—coal, petroleum, and natural gas—have been the major sources of energy. Hydropower and wood were the most used renewable energy resources until the 1990s. Since then, the amounts of U.S. energy consumption from biofuels, geothermal energy, solar energy, and wind energy have increased. Total U.S. renewable energy production and consumption reached record highs in 2020.

In 2020, renewable energy provided about 11.59 quadrillion British thermal units (Btu)—1 quadrillion is the number 1 followed by 15 zeros—equal to 12% of total U.S. energy consumption. The electric power sector accounted for about 60% of total U.S. renewable energy consumption in 2020, and about 20% of total U.S. electricity generation was from renewable energy sources.
