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.

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.

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.

Wind, water and solar sources − the renewable energy trio − could meet almost all the needs of our power-hungry society in 30 years.

LONDON, 19 February, 2020 − Virtually all the world’s demand for electricity to run transport and to heat and cool homes and offices, as well as to provide the power demanded by industry, could be met by renewable energy by mid-century.

This is the consensus of 47 peer-reviewed research papers from 13 independent groups with a total of 91 authors that have been brought together by Stanford University in California.

Some of the papers take a broad sweep across the world, adding together the potential for each technology to see if individual countries or whole regions could survive on renewables.

Special examinations of small island states, sub-Saharan Africa and individual countries like Germany look to see what are the barriers to progress and how they could be removed.
