Slide 1

Solar Energy

Coal is in short supply and nuclear energy is both expensive and potentially harmful to the environment. The solution could be in the use of renewable energy.

Slide 2

Advantages

Running costs are low.

No carbon dioxide emissions to add to the Greenhouse Effect

No sulphur dioxide emissions to cause acid rain.

Solar powered station, California

Slide 3

More Advantages

Solar panels can be quickly set up in remote areas

Local communities can benefit from small scale use of solar power.

Can be used to charge batteries to provide electricity when needed.

Solar cells used to charge batteries

Slide 4

Disadvantages

The initial cost of solar cells can be very high.

The output is dependent on weather conditions and the time of day.

Many solar panels are needed to produce that of a power station

Solar reflector used for cooking

Slide 5

Large areas of land are required for large scale generation of electricity

A warm reliable biome would be needed.

Solar cells have relatively low efficiencies

More disadvantages

Slide 6

Solar energy

Solar energy in use in a mobile home in Arizona.

The solar panels convert the solar energy into electrical energy.

The use of solar cells are also supplemented by the use of wind turbines
