The strategic goal therefore should be: transition to unlimited resources, zero-emission fuels and no options for abuse. Renewable energies, in particular solar energy as the most abundant form, are an alternative for a global energy supply. Solar energy cannot be depleted by using it: it comes to earth at day as light, and leaves to outer space as heat radiation at day and night – whether we “use“ it or not. Being non-material solar energy does not create pollution, and the biotope earth is in natural balance with it. The most efficient places to harvest solar energy in large amounts are the deserts. This paper studies the change in the climate and the related progress in using renewable energy also, the effect of climate change on the future of solar energy, moreover the future of solar energy in Oman. 1.Introduction Climate change has long-since ceased to be a sc ientific curiosity, and is no longer just one of many environmental and regulatory concerns. It is a growing crisis with economic, health and safety, food production, securi ty, and other dimensions. Renewable energy, is energy generated from na tural resourcessuch as sunlight, wind, rain, tides and geothermal heat-which are renewable (naturally replenished), must play a major role in the global energy supply to meet the incr easingly serious environmental and economic threats of climate change. The greatest priority for Earth at this time is not to handle our monetary system, the corrupt politicians, drugs, the news media or even the atomic bomb. The problem is the continuous and expanding by produc ts from burning fossil fuels i.e. pollution, as example figure 1, shows the emissions of co 2 from Oman [1]. Since 1850 there has been a mean rise in global temperature of approximately 1° C (approximately 1.8° F). It was thoug ht that this rise could just be part of a natural fluctuation; such fluctuations have been recorded for tens of thousands of years and operate in short-term as well as long-term cycles [2]. However, 1995 was the warmest year on record, according to the British Meteorological Office. A United Nations panel of scientists attributed the warming to human influence and predicte d that if greenhouse-gas emissi ons [carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons] are not reduced, the average global temperature will rise by 1.0° to 3.5° C (1.8° to 6.3° F), with a best estimate of 2.0° C (3.5° F), by 2100, causing sea level to rise by 20 inches; further warming an sea-level rise woul d follow [2].
