This document discusses alternative sources of energy and the need to transition away from fossil fuels. It begins by defining alternative energy as renewable sources that can replace fossil fuels. There is a need for alternative energy because fossil fuels are finite and burning them contributes to pollution and climate change. While fossil fuel reserves may last decades longer, transitioning to renewable sources like solar, wind, hydroelectric, and wave power is important because they are clean and inexhaustible. The document concludes by stating that alternative energy can mitigate climate change and harnessing diverse renewable resources through research and development is crucial.
