What prime movers have generated the most electricity since 1900?
Prime movers are devices that convert natural sources of energy into mechanical energy to generate electricity. Historically, hydropower from water turbines and steam turbines played major roles. Gas turbines emerged as a more efficient and cost-effective option. In recent years, solar cells and wind turbines have made significant advancements, providing competitive and environmentally friendly alternatives to traditional energy sources.
