AIR AND WATER
AIR AND WATERA major transition in the modern energy age began in the 1970s, when the big nation�s industry started to grow up rapidly. The use of oil was very important and overnight, oil prices shot through the roof, and the trend of ever-cheaper, ever-more-plentiful energy sources were in need.
Another player on the modern energy stage is nuclear power. An industry that didn't exist 40 years ago is now at a huge amount of production, producing 20 percent of the nation's electricity. Ironically, the industry is fading out. New orders ceased 20 years ago, and as aging plants reach the end of their lives, they are closing, one by one. All the non-renewable energy resources have positive and negative affects to the nature. However Nuclear Energy is the most dangerous one, as we can see what happened in Chernobyl in 1986, and it is dangerous if the nations use Nuclear Energy to kill people like at the end of the world war.
It is not a dream to think of solar power that is cheap enough for universal use a world full of zero-polluting electric cars. Wide-scale use of fuel cells for powering buses and other forms of public transport. �Chicago and Vancouver are two cities which have pilot programs using fuel cells to power some of their public transport buses. Use of fossil fuels confined to petro-chemical products and fuel cell feedstock. Nuclear fusion or some other advanced nuclear process, supplying all base load power.� (Solar)
Also, there is continued interest and research into fusion power. Since fusion generates temperatures of millions of degrees, the main difficulty in developing fusion power has been in containing the heat of the reaction. Fusion is an expensive source of energy right now, but it might cost much cheaper in the near future.
It is not very hard to guess that in the near future, all the energy sources will be much cheaper. The technology is changing almost everyday, it was not possible to dream internet ten years ago. Who can guess that what will be happen in the next ten years? But for sure non-renewable energy resources will not be renewed when all of them are used. We always used resources from the nature, now it is time to create our own resources that we can keep the earth and all the organic materials clean. The most green energy resource is solar energy right now and it is very cheap to get heat from the sunlight.
