Clean energy can provide 100% of electricity
All the electricity the world needs can come from clean energy, reliably and throughout the year, British researchers say, at any time of day or night.
Imagine a world with so much renewable, clean energy that it could provide all the electricity society needed, reliably and without any interruption, round the clock. If UK researchers are correct, you shouldn’t need to imagine it. It could soon be a reality.
"RAISING AMBITION. Zero Carbon Scenarios from Across the Globe" - report by the Centre for Alternative Technology (CAT) says clean energy could now meet all our electricity needs, using only existing technology, at all times of the day, and all year round. The report draws on “scenarios” designed to meet the targets of the Paris Agreement, developed at the global, regional, national and sub-national scales.
Scenarios, in the sense used in the report, are emissions reduction models describing possible futures in which society has managed to reduce its emissions of greenhouse gases.
The report’s insistence that renewables can power the world is a challenge to earlier studies which have suggested that the obstacles to a fossil fuel-free economy remain for the moment insurmountable.
The researchers assessed and mapped more than 130 of these scenarios, including 18 in-depth case studies. They draw on cutting-edge modelling work for a net zero world, with deep decarbonisation, and for up to 100% renewable energy. Their geographical range extends from East Africa to the US west coast, and from southern Asia to northern Europe.
