We should all be searching for practical types of renewable energy because the burning of fossil fuels, to generate commercial electricity has a major problem, the whole process is being held globally responsible for the huge environmental damage it is causing, particularly in the emerging economies. The commercial generating process of burning carbon based fuels in exchange for electricity creates, not only waste and potentially damaging gases, but also solid waste that in itself means added problems of disposal. This is particularly true in the case of nuclear power stations, which while a relatively clean and efficient method of generating electricity, it leaves behind enormous amounts of spent fuel rods, the storage of which has global implications.
