Alternative energy sources.
Why the need?
Alternative energy sources.
For global development to be both fair and
sustainable, the rich world may need to cut
energy and resource use by 90% by 2050.
How can this be achieved?
Alternative energy sources.
The use of renewable/alternative energy sources –
 Wind power
 Solar power
 Biomass energy
 Hydroelectricity
 Geothermal energy
All of which, forms of energy which do not use fossil
fuels.

What’s your view of nuclear
energy?
Alternative energy sources.
Nuclear power offers the highest efficiency in
energy production compared to other current
methods. However, the environmental impact
and safety problems resulting from nuclear
energy will not solve the energy problem until
the critical issue of proper nuclear waste
disposal is met.
Alternative energy sources.
We all know the consequences – Chernobyl.
