Biomass or co-fired power station

A power station can generate electricity by burning fossil fuel, but also power stations can be designed to burn fossil fuel and biomass together (called co-firing) or just biomass.

Most co-firing power plants burn solid biomass like wood and agricultural waste along with coal, but some can burn a mix of natural gas and biogas. Because burning biomass is carbon neutral, co-firing reduces the emission of greenhouse gases.

The main advantage of co-firing is that it can be done in existing power plants with little or no modification, allowing for comparatively inexpensive and rapid reductions in greenhouse gases.
