Coal and lignite are the most reliable fuels. We'll depend on them more as gas and oil disappear. There may be a few problems with emissions, but these can easily be solved. They're also very versatile and can be used to produce electricity and heat our homes efficiently.

Fossil fuels are harmful; think how they affect our atmosphere and countryside. We can't build our future energy planning on them. We have to think differently. The sun is a clean energy source, and the potential for providing us with power is enormous! What's more we can install solar cells on buildings, which will reduce the requirement for large power stations.

Solar power is good as far as it goes, but what do you do when the sun isn't shining? In some countries there are often cloudy skies, and in some countries there are only four hours of sunlight per day in winter. Wind on the other hand is always at our disposal – more than the sun anyway to cover our needs.

The most important thing is to educate people about energy. It may be true that fossil fuels and other sources have some drawbacks, but there are many positive aspects. We should focus on informing people; how they see energy is important.
