Scientists at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) have set a world record in solar cell efficiency with a photovoltaic device that converts 40.8% of the light that hits it into electricity. However, it was only under the concentrated energy of 326 suns that this was achieved.
This timeline of sustainable energy research from 2020 to the present documents research and development in renewable energy, solar energy, and nuclear energy, particularly regarding energy production that is sustainable within the Earth system. Renewable energy capacity has steadily grown, led by solar photovoltaic power. [1]
The development of renewable energy and energy efficiency marked "a new era of energy exploration" in the United States, according to former President Barack Obama. [9] In a joint address to the Congress on February 24, 2009, President Obama called for doubling renewable energy within the following three years.
