Renewables experts also reaffirmed his appeal for the world's political leaders to back technologies that would develop the use of solar energy as a non-polluting power source. "Political will is the key, it's the issueÉThe technology is there, the economics are closeÉIt's the politicians that can make this work. The scientists cannot make it work," said Peter Dearlove of the International Solar Energy Society (ISES). "What we are hoping is that governments of the world will recognise the cost of the other energy sourcesÉRenewable energy is cheaper if you take into account that oil and coal are very expensive in terms of what they are doing to the planet and to people."
He said the world should move to renewable and non-polluting energy sources because fossil fuels are running out and their use harms the environment. The conference revealed statistics showing that known world oil reserves could run out in the next 45 years, natural gas in 67 years and coal in 240 years. "The developed world is going to be using up energy in the next ten years faster and faster," said Michael Nicklas, ISES president. Developing countries -- three-quarters of which were net importers of oil -- had to move away from fossil fuels to solar power if they were to reduce debt now exceeding $1.8 trillion, he added.
