Expansion of wind and solar power too slow to stop climate change

2

Newswise — The production of renewable energy is increasing every year. But after analysing the growth rates of wind and solar power in 60 countries, researchers at Chalmers University of Technology and Lund University in Sweden and Central European University in Vienna, Austria, conclude that virtually no country is moving sufficiently fast to avoid global warming of 1.5°C or even 2°C.

“This is the first time that the maximum growth rate in individual countries has been accurately measured, and it shows the enormous scale of the challenge of replacing traditional energy sources with renewables, as well as the need to explore diverse technologies and scenarios,” says Jessica Jewell, Associate Professor of Energy Transitions at Chalmers University of Technology.

The Intergovernmental Panel on Climate Change (IPCC) has identified energy scenarios compatible with keeping global warming under 1.5°C or 2°C. Most of these scenarios envision very rapid growth of renewable electricity: on average about 1.4 per cent of total global electricity supply per year for both wind and solar power, and over 3 per cent in more ambitious solar power scenarios. But the researchers’ new findings show that achieving such rapid growth has so far only been possible for a few countries.
