, sorted by type and name. In 2020, Maine had a total summer capacity of 4,875 MW through all of its power plants, and a net generation of 10,002 GWh. The corresponding electrical energy generation mix in 2021 was 27.1% hydroelectric, 24.7% natural gas, 23.3% wind, 19.9% biomass, 2.4% non-biogenic waste, 1.6% solar, 0.6% coal, and 0.4% petroleum. Small-scale solar, which includes customer-owned photovoltaic panels, delivered an additional net 136 GWh of energy to the state's electrical grid. This was about equal to the amount generated by Maine's utility-scale photovoltaic plants. During 2021, renewable sources generated 74% of all electrical energy from Maine, making it one of the top-five U.S. states. Maine's share of wind generation is the largest among New England states, and its share of biomass generation from the wood industry and municipal waste sources is the largest in the United States. Maine's electricity generation has not met the in-state demand in recent years, and about one-quarter of its electricity consumption was imported from Canada.
