Environmental impacts remain a concern, necessitating focus on sustainable practices in hydropower development.
Biomass
Biomass energy converts organic materials, like agricultural waste and dedicated energy crops, into electricity or fuels. This process can reduce waste while producing clean energy. Biomass power plants can operate similarly to fossil-fuel plants, allowing for a smoother transition in energy systems. According to the U.S. Energy Information Administration, biomass contributes about 1.4 percent of U.S. electricity generation. The utilization of biomass supports local economies and reduces reliance on fossil fuels.
Geothermal Energy
Geothermal energy taps into the earth’s internal heat to produce electricity and provide direct heating. This renewable resource requires drilling wells to access hot water or steam beneath the surface. Geothermal power plants offer a continuous energy supply, unlike intermittent sources. In 2022, geothermal energy accounted for about 0.4 percent of U.S. electricity generation. As technology advances, geothermal energy exhibits potential for growth in sustainable energy portfolios.
