Solar is expected to account for almost half of electricity supply by 2050

The White House on Wednesday presented a plan for solar power to provide nearly half of the country’s electricity by 2050. The ambitious roadmap envisions increasing solar power production by 3% of by 2020 to 40% by 2035, to finally reach 45% by 2050.

The realization of this plan would require enormous expenditure in all industries. US solar installations reached record levels in 2020, but annual growth in solar capacity is expected to double by 2025, before quadruple from 2020 levels each year between 2025 and 2030. Supportive policies, including a lower costs and tax incentives have fueled the strong growth in solar power. the last decade.

The report published by the Office of Solar Energy Technology of the United States Department of Energy and the National Renewable Energy Laboratory indicates that solar capacity will have to reach 1,600 gigawatts by 2050. This exceeds the total electricity consumption of residential buildings and commercial today.

The solar power study builds on the Biden administration’s broader plan for an emissions-free grid by 2035, with widespread decarbonization of the energy system by 2050. Others would explain the production not provided by zero carbon energy sources, especially wind. Solar.

“The study highlights the fact that solar power, our cheapest and fastest growing clean energy source, could produce enough electricity to power every home in the United States by 2035 and 1.5 million people in the process. ” jobs, ”Energy Secretary Jennifer Granholm said in a statement.

The report comes at a time when extreme weather events due to climate change have wreaked havoc on the U.S. electricity grid.

“It’s code red,” President Joe Biden said on Tuesday during a visit to areas of New York and New Jersey affected by Hurricane Ida. “Climate change is a potential threat to our lives, to our economy. And the danger is there, it will not improve, ”he said. “The country and the world are in danger.

The president’s language is that of UN Secretary-General Antonio Guterres when he called the latest report of the Intergovernmental Panel on Climate Change a “code red for humanity”.

For the United States to meet its targets, it will need to make significant developments around grid flexibility, including energy storage as well as transportation expansion.

The infrastructure package passed by the Senate in August included billions of dollars for clean energy projects, but left out several key policies, including expanding tax credits. However, this initiative and others could still be included in the $ 3.5 trillion budget proposal approved by the House in August.
