needed for its future growth, in particular African oil and gas reserves.
Maybe we
need to be open to the idea that large

If you don't want to live near a road,

Nuclear
power stations can be built where the

for example, coal - fired
power stations that

India is also the world's fifth largest greenhouse gas emitter, according to the latest reliable information (CAIT 2007), with a heavy reliance on coal
