What is the difference between conventional and non conventional energies?

Conventional energies are the ones that up until and including now are the ones that have been predominantly used, such as fossil fuels and natural gas and mineral oil. Conventional energy is also referred to as non-renewable energy because once it has gone, that's it.

Non conventional energy is the energy that is not the predominant one, but there is lots of effort being made to make sure that will change, although currently the amount of this energy on national levels is minimal.

Sources of non conventional energy are solar, wind, atomic, geo thermal and bio gas. These energies are also referred to as renewable energy sources because they are not reliant on the earth's finite resources.

• Green power

The world is slowly waking up to the fact that it is fast running out of resources and that humans are responsible for creating the potential devastation to the planet.

Governments (some more actively than others) are not only urging populations and manufacturers to take an active role in reducing our carbon footprints, but are using legislation and taxation to impel people to comply.

• Schemes

There are many different schemes that have been put into place to encourage people to turn to non conventional sources of power in order to slow down global warming.

An example of one of these schemes is the Feed In Tariff in the United Kingdom, whereby people are able to sell their unused electricity back to the national grid as long as it was produced by a renewable source such as wind turbines or solar panels.
