• biomass

Name the type of renewable energy described:

Cold water is heated by underground rocks

• wind turbines

• geothermal

• solar panels

• hydroelectric

Name the type of renewable energy described:

Plants are grown and then burned

• solar panels

• geothermal

• biomass

• hydroelectric

Name the type of renewable energy described :

Light energy is converted to electrical energy

• solar panels

• wind turbines

• geothermal

• hydroelectric

Dammed water changes kinetic energy into electrical energy

• solar panels

• wind turbines

• geothermal

• hydroelectric

State the advantage of wind turbines

State one disadvantage of wind turnines

What is the advantage of the solar energy

• They only work in day light; less direct sun means less energy available

• Difficult to predict energy availability due to changing weather

• No pollution, caused by electricity production

State the disadvantage of the solar energy

• Dam building and flooding of valleys can cause large scale loss of habitats

• Solar cells and thermal panels are expensive and require space.

• Very low maintenance and production cost once set up
