Alternative Energy

Fossil Fuels• Fossil fuels are a very efficient

way to produce energy!• However…– Burning Fossil fuels creates

POLLUTION.– Coal mining is dangerous and

destroys the Earth’s landscape.– Fossil Fuels are NOT a renewable

electricity directly from

sunlight with special

materials.

• Solar electricity can also be generated from the sun’s heat instead of burning fossil fuels.

Water EnergyHydroelectric, wave, tide

The movement of water can be used to generate

electricity!

Geothermal Energy
