A new U.S. Department of Energy study has found that solar energy can supply 40% of the country’s electricity supply by 2035, and 45% by 2050.
Clean energy could produce enough electricity to power all of the homes in the U.S. by 2035 and employ as many as 1.5 million people in the process,” Secretary of Energy Jennifer M. Granholm said on September 8 in marking the release of the 2021 Solar Futures Study.
Studies like these are a great way to encourage bold action at the federal and state levels. The United States has committed to reducing carbon emissions by 50%-52% by 2030. It also plans on achieving carbon-free electricity in 2035 and carbon neutrality by 2050.
There are many technologies that convert sunlight’s heat and light into solar energy.
solar power technologies are:
● Photovoltaics (PV), such as solar panels, convert sunlight directly into electricity by using semiconductors.
● Concentrating solar power plants (CSP) use mirrors to direct the sunlight to a central point. This heat is enough to fuel steam turbines and engines that produce electricity.
● Solar heating and cooling systems (SHC), which use thermal heat from the sun in order to produce hot water and air conditioning, replace the need for electricity and natural gas.
John Kerry, Special Presidential Envoy for Climate Change, stated that solar and wind power were the most cost-effective sources of electricity in countries accounting for 77 percent of global GDP.
The Department of Energy’s 2021 Solar Futures Study (PDF 11.7MB) shows that solar power can be a significant and cost-effective tool in ending America’s dependence on fossil fuels.
It claims that switching to renewable energies such as solar and wind will result in approximately 3 million American jobs and a reduction in energy bills for consumers.
According to the Department of Energy, solar power could provide as much as 40% of the country’s energy supply. The study reveals that electricity demand is expected to rise by 30% between 2020-2035.
Energy-grid resilience can also be improved by using better storage methods for solar energy. Solar batteries store extra energy during sunny days and make it available when traditional energy lines are down.
The study concludes that this means reliable energy at lower prices. Other countries can also benefit.
President Biden stated that making these bold investments is not just good climate policy. He said it at the 76th session of the United Nations General Assembly. “It’s an opportunity for each country to invest in itself and our future.”
