  1. Advantages & Disadvantages of Energy Resources

  2. Geothermal • Advantages • Low cost • Inexhaustible • No environmental impact • Pumps can store heat for later use. • Disadvantages: • Source is close to volcanic activity. • Some plants use lots of water – creating water pollution. • Supply could change. • Cannot be transported. • High start up cost.

  3. BIOMASS • Advantages • Produces less harmful greenhouse gases. • Can be sustainable. • Can be used for different purposes. • Disadvantages: • Takes a lot of space. • Not entirely clean. • Expensive • Not easily transported.

  4. Wind • Advantages • It’s free • Does not produce pollutants • Disadvantages: • Strength of the windmill varies. • Noisy/Unsightly • Large wind farms are needed to produce enough electricity.

  5. NATURAL gAS • Advantages • Cleanest fossil fuel available. • Cheap. • Easy to transport • Disadvantages: • Contributes to greenhouse gases. • Explosive • Nonrenewable

  6. Oil • Advantages • A small amount can produce a lot of energy. • Easy to transport and produce. • Constant power source and it’s reliable. • Disadvantages: • Creates greenhouse gases. • Pollution • Nonrenewable • Increase in violence.

  7. Hydropower • Advantages • Stable source • Clean • Disadvantages: • Expensive to build dams • Droughts affect production • Environmental changes because of the dam.

  8. Nuclear power • Advantages • Does not emit CO2 pollutants • Continuously generates electricity. • Disadvantages: • Expensive to start and maintain power plants. • Safety concerns. • Waste that remains toxic for many years. • Non-renewable
