Energy Source Efficiency
During this power point we are going to be investigating the efficiency of different energy sources. We have collected information to show peoples views on the different energy sources and their efficiency’s.
We will also be telling you, what they feel is the most energy efficient transport.

Solar has no effectsHydroelectric, it could harm animals living in
the water.Coal, it is non-renewable and will be used
quickly.Wind, birds could get harmedNatural Gas, it can pollute the ozoneNuclear, if there is a leak it will cause

We found that the majority of people would use solar energy as it seems to be the most efficient.
It does not pollute, it is a constant energy and although costly to install in the long run it is very economical
Also people are using solar energy we should concentrate on using renewable energy sources e.g. solar and wind instead of non-renewable e.g. coal
Many people think we should use public transport or invest in the electric car when it is introduced to S.A
Thank you :D :D
