When it comes to cost, wind and solar projects beat coal

Updated: Nov 3, 2022

Almost two-thirds of wind and solar projects built globally last year will be able to generate cheaper electricity than even the world’s cheapest new coal plants, according to a report from the International Renewable Energy Agency (IRENA).

The agency found that the falling cost of new wind farms and solar panels meant 62 per cent of new renewable energy projects could undercut the cost of up to 800 gigawatts (GW) worth of coal plants, or almost enough to supply the U.K.’s electricity needs 10 times over.

Solar power costs fell by 16 per cent last year, according to the report, while the cost of onshore wind dropped 13 per cent and offshore wind by nine per cent. In less than a decade, the cost of large-scale solar power has fallen by more than 85 per cent while onshore wind has fallen almost 56 per cent and offshore wind has declined by almost 48 per cent. Francesco La Camera, IRENA’s director general, said the agency’s latest research proved the world was “far beyond the tipping point of coal.”

He said: “Today, renewables are the cheapest source of power. Renewables present countries tied to coal with an economically attractive phase-out agenda that ensures they meet growing energy demand, while saving costs, adding jobs, boosting growth and meeting climate ambition.”

In Europe, the cost of a new coal plant would be well above the cost of new wind and solar farms including mandatory carbon prices. The report found that in the U.S., renewable energy could undercut between three-quarters and 91 per cent of existing coal- fired power plants, while in India, renewable energy would be cheaper than between 87 per cent and 91 per cent of new coal plants.

Replacing hundreds of existing coal plants with unsubsidized renewable energy sources could save $32.3 billion every year in energy system costs and avoid about three gigatonnes of CO2 annually, the report said.

The carbon saving from phasing out 800GW of coal power capacity would be the equivalent of shaving nine per cent from the world’s energy-related emissions last year, according to the report, or 20 per cent of the carbon savings needed by 2030 to help limit global heating to 1.5 C above pre-industrial levels.

The report predicts the cost of renewable energy will continue to fall in the coming years. Over the next two years, three-quarters of all new solar power projects will be cheaper than new coal power plants, and onshore wind costs will be a quarter lower than the cheapest new coal-fired option.

“The trend confirms that low-cost renewables are not only the backbone of the electricity system, but that they will also enable electrification in end uses like transport, buildings and industry and unlock competitive indirect electrification with renewable hydrogen,” the report said. than-coal-report
