This document discusses energy conservation and various energy sources. It notes how people historically used energy sources like water, wind and burning wood. With the Industrial Revolution, fossil fuels like coal, oil and gas became primary energy sources but are non-renewable. To avoid depleting fossil fuel reserves, it is important to conserve energy and explore renewable alternatives like solar, wind, hydroelectric and geothermal. Individuals can help by insulating homes, using appliances efficiently, and carpooling or taking public transportation.
