In a sign of the shift away from fossil fuels that is starting to take hold in some regions, G20 countries collectively produced eight percent of their electricity from solar farms, wind parks and other green power stations in 2015, up from 4.6 percent in 2010, FT reported.
Seven G20 members now generate more than 10 percent of their electricity from these sources, compared with three in 2010.
The seven were led by Germany, home of the Energiewende — a policy shift towards green power. Renewables made up 36 percent of its electricity mix, according to data compiled for the FT by the Bloomberg New Energy Finance research group.
The UK, Italy and France all generated more than 19 percent of their electricity from renewables while Australia and Brazil reached 11 percent and 13 percent respectively. For the 28 members of the EU, the number was 18 percent.
The figures do not include hydropower, one of the oldest sources of renewable electricity.
Instead, the data underline the growth of newer forms of green energy such as solar and wind farms that have been heavily subsidized in many countries as governments try to combat global warming.
This growth has been especially striking in the UK, which generated 24 percent of its electricity from such renewables last year compared with just six percent in 2010.
Still, fossil fuels continue to dominate the electricity supply in many countries, including the US and China, two of the most powerful proponents of the UN climate change accord struck in Paris in December.
China is the world’s largest clean energy market, accounting for nearly a third of the $329 billion invested in clean energy globally last year as the government continued to boost its renewables industry.
