Fossil Fuels: Declining but Persistent

Fossil fuels - coal, oil, and natural gas - remin dominat in global generation; accounting for rougly 60% of supply. Their high energity density and constructura I provides reliability and cost competiveness. Howevevel, their long-term supplity is selely contenged by greenhouses gas emissions, ensicé depletion.

Hydroelectric and Geothermal Energy

Hydropower provides reliable basload electricity with century- long operational lifespans. Large dams, however, can disrult river ecosystems, displacee communities, and generate metane from flowded biomass. Run- of-river and small-scale hydro designs reduce these impacts but have e lower capacity factors.
