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]
2008 - New record achieved in solar cell efficiency. 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 ...
If renewable energy is to be developed to its full potential, America will need coordinated, sustained federal and state policies that expand renewable energy markets; promote and deploy new technology; and provide appropriate opportunities to encourage renewable energy use in all critical energy market sectors: wholesale and distributed ...
Renewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries. [ 200 ]
First public television broadcasts in the UK by John Logie Baird between London and Glasgow and in the US by Frederic Eugene Ives (1882–1953) between Washington and New York. The American inventor Philo Taylor Farnsworth (1906–1971) developed in Los Angeles, the first fully electronic television system in the world.
The word energy derives from Greek word "energeia" (Greek: ἐνέργεια) meaning actuality, which appears for the first time in the 4th century BCE in various works of Aristotle [1] when discussing potentiality and actuality including Physics, Metaphysics, Nicomachean Ethics [2] and On the Soul.
MIT App Inventor (App Inventor or MIT AI2) is a high-level block-based visual programming language, originally built by Google and now maintained by the Massachusetts Institute of Technology. It allows newcomers to create computer applications for two operating systems: Android and iOS , which, as of 25 September 2023 [update] , is in beta testing.
The Lower Paleolithic period lasted over 3 million years, during which there many human-like species evolved including toward the end of this period, Homo sapiens.The original divergence between humans and chimpanzees occurred 13 (), however interbreeding continued until as recently as 4 Ma, with the first species clearly belonging to the human (and not chimpanzee) lineage being ...
