OA2.1 Understand energy and its conservation

OA2.1.2 Explain the effects of various forms of energy on the environment

(Solar energy)

energy from the Sun

in the form of heat and light

Word Definition Picture

Solar Energy

Creates electricity

Renewable resource

Solar Power use solar panels to trap the Sun’s energy.

This energy can be used to create electricity or heat hot water.

How does Solar energy effect our environment?

The good news:

1. Running costs are low (low $)

2. No carbon dioxide emissions

3. No sulphur dioxide emissions to cause acid rain

How does Solar energy effect our environment?

More good news:

4. Solar panels can be quickly set up in remote areas

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

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

1. The initial cost is high!

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

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

Solar reflector used for cooking

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

5. A warm reliable biome would be needed.

6. Solar cells have relatively low efficiencies
