A data analytics firm, TransitionZero, has found that switching away from coal to clean energy is cheaper than switching to gas, as the call to limit global heating by 1.5 degree Celsius continues.

Electricity and heat production along with other energy uses account for 35 per cent of global greenhouse gas, highlighting the contribution of energy production and use to climate change.

Chief among the offenders is coal— the single biggest contributor to climate change; coal burning is responsible for 46 percent of CO2 emissions across the globe, making up 72 percent of all GHG emissions in the electricity sector.

According to TransitionZero’s findings, shifting away from coal to renewable energy sources has never been cheaper—and it’s now cheaper than switching to gas.

Jacqueline Tao, an analyst at TransitionZero, said:

“The carbon price needed to incentivize the switch from coal generation to renewable energy for storage has dipped to a negative price. So essentially that means that you can actually switch to renewables at a cost-saving.”

The report finds that the global average cost of switching from coal to renewable energy has dropped an astounding 99 percent since 2010, compared to the cost of switching from coal to gas.

The research shows that the carbon price of the coal-to-clean energy switch has declined to $62 per ton of CO₂ emitted on average in 2022 compared to $235/tCO₂ in the switch from coal to gas.

Using its coal to Clean Carbon Price Index, TransitionZero measured the carbon price level for 25 countries if they made the switch from coal to renewable energy sources such as wind or solar.

The group said the information challenges claims that natural gas, with its lower carbon intensity than coal, is a reliable “bridge fuel” in the transition to more sustainable energy sources. Instead, it says companies should make the leap directly to renewables.

Funding for Renewable Energy

The Group noted that there are financial incentives for making the switch. “Banks are increasingly finding it risky to lend to these fossil fuel assets in the concern that they will become stranded assets in the near term down the road due to the global energy transition,” Tao said.

“That’s going to mean that there’s going to be limited upstream supply that’s going to come online, and we are going to see increasingly tight gas markets and fossil fuel markets in general that will be prone to demand and supply shocks.”

However, coal is still big business. Earlier this year, a report found that some of the world’s leading financial institutions pledged to go net-zero but then underwrote more than $1.5 trillion in debts for the coal industry over the last two years.

“It’s long been known that the coal industry is the number one driver of our planet’s rising temperature,” Katrin Gaswindt, head of financial research at the environmental nonprofit Urgewald that concluded the research, said in a statement.

“But who is providing the loans, the underwriting services, and the investments that allow these companies to keep on operating?” Gaswindt added.
