Plunging cost of wind, solar marks turning point in energy transition
Such lowered prices can help governments embrace green economic recoveries
London
PLUNGING costs of renewables mark a turning point in a global transition to low-carbon energy, with new solar or wind farms increasingly cheaper to build than running existing coal plants, said a report published by the International Renewable Energy Agency on Tuesday.
The agency said the attractive prices of renewables relative to fossil-fuel power generation could help governments embrace green economic recoveries from the shock of the novel coronavirus pandemic.
"We have reached an important turning point in the energy transition," the agency's director-general Francesco La Camera said in a statement.
Although scientists say the world needs to stage a much faster transition to mitigate the worst impacts of climate change, the annual report by the Abu Dhabi-based agency shows that wind and solar are increasingly competitive on price alone.
More than half of the renewable capacity added in 2019 achieved lower power costs than the cheapest new coal plants, the report found.

Auction results also suggest that the average cost of building new solar photovoltaic (PV) and onshore wind power now costs less than keeping many existing coal plants running, reinforcing the case for phasing out coal, the report said.
The authors also calculated that the world could save up to US$23 billion of power system costs per year by using onshore wind and solar PV to replace the most expensive 500 GW of coal-fired power, mostly found in China, India, Ukraine, Poland, South Korea, Japan, Germany and the United States.
Such a switch would also reduce global carbon dioxide emissions by about the equivalent of 5 per cent of the total carbon dioxide emissions in 2019.
Next year, up to 1,200 GW of existing coal capacity could prove more expensive to operate than the cost of building new utility-scale solar PV farms. REUTERS
