The article discusses using plant-based biomass fuels instead of fossil fuels like coal for making electricity to cut down global warming emissions. Currently, only 1% of U.S. electricity comes from biomass. As old fossil fuel power plants get replaced, there may be chances to switch to biomass for lower emissions. Factors influencing this switch include electricity demand growth, fossil fuel prices, and new technologies. High demand for electricity, fuel prices, and evolving technologies affect how much biomass can enter the electricity market.
