New solar and wind farms will soon cost less than many of the world’s coal-fired power plants, and governments should invest in them to boost economies amid the coronavirus, according to the International Renewable Energy Agency. Coal plants with a capacity of up to 1,200 gigawatts will probably be more expensive to run by next year than new, large-scale photovoltaic solar plants, said the organization, which advises countries on curbing their use of fossil fuels.
“Renewables must be the backbone of national efforts to restart economies in the wake of the Covid-19 outbreak,” the Abu Dhabi-based agency’s director general, Francesco La Camera, said in a report Tuesday. “We have reached an important turning point in the energy transition.”
Replacing 500 gigawatts of high-cost coal plants with solar and wind farms would reduce carbon emissions by about 1.8 gigatons, equivalent to 5% of CO2 emissions in 2019, and save consumers billions of dollars, Irena said. Power generated from coal mostly comes from the U.S., China, India, Poland, Germany, South Korea and Ukraine.
Irena expects the cost of installing renewables to continue falling in 2021 — to $0.043 kilowatt hour for onshore wind, down 18% from 2019, and to $0.039/kWh for large photovoltaic plants, 42% lower than last year.
“Auction results show this trend accelerating, reinforcing the case to phase out coal entirely,” Irena said.
Still, research from the Paris-based International Energy Agency suggests new power from wind and solar will fall this year for the first time in two decades as factory closures delay the construction of renewable facilities.
The cost of solar and wind energy could be consistently cheaper than conventional supplies by 2030, Irena said in January.
The trend is largely down to advances in technology and the increasing scale of projects. Photovoltaic power has seen an 82% decline in costs since 2010 and onshore wind 39%, according to Irena.
