Top 15 Renewable Energy Companies in USA

About 80% of the energy in the US comes from fossil fuels, however, there are American renewable energy companies that are working towards a greener future for the country.  

Wind and solar are the fastest-growing renewable energy sources in the USA but only provide about 3.8% of the total energy production. However, it is expected to grow heavily with predictions of up to 73 GW of renewable energy being produced by 2030. 

The state government is issuing Renewable Portfolio Standards (RPS) which mandates the generation of renewable and clean energy cutting down on carbon emissions. As of September 2020, thirty-seven districts, the District of Columbia, and four US territories are set with RPS. Similarly, federal incentives on tax are also expected to cut down the upfront costs by more than 15% while subsidies for fossil fuel generation are set to be reduced. 

Renewable energy has great potential in the USA with equal opportunities to promote a sustainable future for the country. Today, let us dive into the renewable energy company in the USA which is leading the industry to make a cleaner and greener future possible. These companies are majorly active in wind & solar energy, however, production from hydroelectricity, geothermal energy, biogas & biofuels is also increasing rapidly.

With constant innovation and talented teams, these companies are working to increase the effectiveness of production as well as to distribute it to larger masses. 

What are the major sources of renewable energy in America?


The major sources of renewable energy in the USA include hydropower and wind for electricity and biofuels and wood as biomass. 

The USA is the 4th largest producer of hydroelectricity in the world, which accounts for 45.71% of the nation's total renewable electricity and 6.5% of the nation's total electricity. Similarly, 5.5% of total country production came from wind capacity, most of which comes from Texas, Iowa, and Oklahoma. 

Solar power is also increasing its contribution to the nation's electricity production by 1.3%. Other renewable sources of energy include ). The US has also pioneered solar thermal energy production which also contributes as a renewable energy source for the USA. 

Other renewable energy sources include geothermal, with The Geysers in Northern California the most important geothermal complex within the world.
