Benefits of Renewable Energy Use
Although renewable facilities require upfront investments to build, they can then operate at very low cost (for most clean energy technologies, the "fuel" is free). As a result, renewable energy prices can be very stable over time. Moreover, the costs of renewable energy technologies have declined steadily, and are projected to drop even more.

Solar Energy
Solar energy is a form of renewable energy, in which sunlight is turned into electricity, heat, or other forms of energy we can use is a "carbon-free" energy source that, once built, produces none of the greenhouse gas emissions that are driving climate change. Solar is the fastest-growing energy source in the world, adding 270 terawatt-hours of new electricity
Renewables Were The World''s Cheapest Energy Source in 2020
Renewable energy was the cheapest source of energy in the year 2020. The cost of renewable technologies like wind and solar is falling significantly, according to a new report. Most renewable power is now being generated more cheaply than the cheapest new fossil fuel options. It''s progress, says the International Renewable Energy Agency.

It can be converted to create biodiesel for vehicles, methane gas, and a range of other biofuels, heat homes, and generate electricity.
U.S. Renewable Energy Factsheet
82% of U.S. energy comes from fossil fuels, 8.7% from nuclear, and 8.8% from renewable sources. In 2023, renewables surpassed coal in energy generation. 1 Wind and solar are the fastest growing renewable sources, but contribute less than 3% of total energy used in the U.S. 1 Levelized Cost of Energy (LCOE) is measured as lifetime costs divided by energy production.
Renewables became the second-most prevalent U.S. electricity
In 2020, renewable energy sources (including wind, hydroelectric, solar, biomass, and geothermal energy) generated a record 834 billion kilowatthours (kWh) of electricity, or about 21% of all the electricity generated in the United States.Only natural gas (1,617 billion kWh) produced more electricity than renewables in the United States in 2020. .
