Name 3 advantages of water power
Water power in its various forms is a renewable energy resource and there are no fuel costs. No harmful polluting gases are produced. Tidal barrages and hydroelectric power stations are very reliable and can be easily switched on.
4 of 8
Name 3 disadvantages of water power
The rotting vegetation underwater releases methane, which is a greenhouse gas. Tidal barrages destroy the habitat of estuary species, including water birds. It has been difficult to scale up the designs for wave machines to produce large amounts of e

How is wind produced?
Wind is produced as a result of giant convection currents in the Earth's atmosphere, which are driven by heat energy from the sun.

Name 2 advantages of wind power
Wind is a renewable energy resource and there are no fuel costs and no harmful polluting gases are produced.
7 of 8
Name 3 disadvantages of wind power.
If there is no wind there is no electricity. The amount of electricity produced depends on the strength of the wind. Wind farms are noisy and may spoil the view for people living near them.
