A study finds that the world has enough rare earths and other raw materials to switch from fossil fuels to renewable energy. [172] [173] A new viable lithium-ion battery recycling method is reported. [174] [175] Flow chart of proposed or possible product stewardship scheme for new solar PV panels [176]
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.
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 ]
An energy transition is a broad shift in technologies and behaviours that are needed to replace one source of energy with another. [14]: 202–203 A prime example is the change from a pre-industrial system relying on traditional biomass, wind, water and muscle power to an industrial system characterized by pervasive mechanization, steam power and the use of coal.
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.
Last but not least, add Occidental Petroleum (NYSE: OXY) to your list of renewable energy stocks to buy in 2025 and hold for a few decades. OK, it's not a renewable energy stock. Occidental is ...
It is based increasingly on renewable energy and materials, and it is accelerated by digital innovation. It is a resilient, distributed, diverse, and inclusive economic model. The circular economy is an economic concept often linked to sustainable development , provision of the Sustainable Development Goals (Global Development Goals), and an ...
Renewable energy has a history of strong public support. In America, for example, a 2013 Gallup survey showed that two in three Americans want the U.S. to increase domestic energy production using solar power (76%), wind power (71%), and natural gas (65%). Far fewer want more petroleum production (46%) and more nuclear power (37%).
