The document discusses renewable and non-renewable sources of electrical power. Renewable sources include solar, wind, water/hydro, and biomass, which are replenished naturally and available continuously. Non-renewable sources such as coal, nuclear, oil and natural gas are exhausted after use and may not be replenished, often producing pollution. The document also outlines the process of generating, transmitting and distributing electricity through generating systems, transmission lines, transformers and distribution lines to residences.

9. ➢ May not be replenished by nature or take long
geological time to be formed again.
➢ Resources are exhausted after use.
➢ Examples are coal, nuclear, oil, natural gas.
➢ Most of the time gives pollutants and not eco-friendly.
