Is the electric grid really clean? I thought the grid was powered by polluting coal plants?
Approximately half of the nations electric grid is powered by coal-fired power plants, but compared to the burning of fossil fuels, electricity is still over 50% cleaner. Additionally, the electric grid is increasingly clean energy, which is defined as any source of energy that is renewable and produces little to no pollution, which include solar, wind power, biomass, hydro-power, and landfill gas. Solar power is derived from photovoltaic panels that capture the power of the sun to produce electricity or to heat water. Wind power comes from high-tech turbines mounted on towers, which spin when the wind blows, creating electricity. Biomass is a name for crops grown specifically for energy production. When these crops are burned, they often produce far less air pollution and global warming gases than fossil fuels. Some examples of biomass are switch grass, corn, and soybeans. Low Impact Hydro power comes from hydro electric facilities that are built in such a way that they do minimal dam
