Students classify energy resources such as coal, natural gas, uranium, wind, solar, hydroelectric, geothermal and biomass as renewable or non-renewable, and trace the energy transformations in a power station and generator. They interpret electricity-generation data with percentage calculations, calculate the power output of a wind farm and evaluate the advantages and disadvantages of different resources.

When evaluating, give both sides (advantages and disadvantages) before your recommendation.
Non-renewable resources will run out because they took millions of years to form or exist in a limited amount. They include the fossil fuels (coal, oil and natural gas) and nuclear fuels such as uranium.
Renewable resources are naturally replaced: sunlight (solar), wind, moving water (hydroelectric, tidal and wave), heat from inside Earth (geothermal) and biomass (plant and animal material).
Most power stations work the same way: something makes a turbine spin, and the turbine turns a generator, where a magnet rotates near coils of wire to produce electricity. In coal, gas and nuclear power stations, heat boils water into high-pressure steam, which spins the turbine.
A region's electricity generation for one year came from: coal 30%, natural gas 18%, wind 20%, solar 16%, hydroelectric 12% and other sources 4%.
