Speaking: Alternative energy sources

1(P110)

a)Wind power has already been implemented in many countries though some people say it can never provide enough energy on its own.The initial cost is also very high.

b)Solar power is being widely used either on people's own houses or in the form

of huge areas of land with solar panels.The cost of technology is falling for this energy so it looks like a good investment.

c)Bio fuels which make use of residue from plants are already used in some

cars.They look set to provide one solution to the lack of petrol fuels.

d)Coal is criticised for the pollution it creates and many countries are looking at alternatives which suggests it isn't a good investment. However,in some parts of the world such as China there are huge coal reserves which are only now being mined and used in power stations. In this case coal may still be a good investment but be bad for the environment.

e)Wave power has many of the same pros and cons as wond power.

f)Nuclear power has attracted bad publicity in the past but more recently many governments have returned to the idea of building nuclear power stations in the next

century in order to solve the potential shortage of energy. Private investment may yet provide good returns.
