    Type of Energy

    Uploaded by

    api-406507477
    This document summarizes different types of renewable and non-renewable energy sources, including their advantages and disadvantages. Solar and wind energy are obtained from sunlight and wind respectively, and have potentially infinite supplies but high upfront costs. Tidal energy uses tidal movements but requires costly barrages and has environmental impacts. Geothermal energy harnesses underground heat but is only viable in volcanic areas. Biomass and wood provide readily available energy when burned but release pollutants if not sustainably managed through replanting. Hydroelectric power generates electricity through water movement but can damage landscapes and communities.
