This is because wood is reportedly both less efficient at the point of combustion and has larger processing and supply chain emissions than coal. Their research shows that using wood instead of coal in power generation increases the amount of CO2 in the atmosphere, worsening climate change until—and only if—the harvested forests regrow.

In Ohio, electricity is mainly generated using resources like coal, natural gas and nuclear. While these resources are found naturally in the earth and produce large amounts of electricity, nonrenewable resources take a long time to form, and there is a limited supply available for people to use for power generation.
The map shows coal capacity, whereas electricity generation and CO2 emissions depend on a range of other factors. Most important is how often coal plants run – their load factor. Global average loads started falling in 2007 and coal power CO2 has levelled off since 2014. More on this below.
