Human face energy crisis Fire is man's first energy used for heating, cooked food, and even to disperse beast. The application of fire to improve the human civilization, enhancing the heat, but also to humanity from the Stone Age into the Bronze Age. Up to the 18th century Industrial Revolution in Britain, driven by steam engine built in a modern civilized society, the steam will heat into mechanical energy, and promote the mass production. After that the construction of thermal power plants, oil exploration, the emergence of gasoline engines, the application of nuclear power plants, coal, oil, natural gas, uranium and other natural resources continue to be mined to provide mankind with energy. According to the report of the U.S. Department of Energy, the world's electricity consumption in 2003 was 14.8 trillion degrees, including developed countries accounting for 29%, 71% of the remaining countries is expected to more than double by 2030, reaching 30.1 trillion degrees. Current coal still dominates, accounting for 20% followed by natural gas power, oil and electricity 10%, the rest is nuclear, water, sun, wind and so on. However, reserves of natural resources are limited, according to the development of today's consumption level is expected to 20 to 30 years of this century, mankind is about to encounter major energy crisis. Therefore, every country in the world for this huge problem and dedication to explore all possible solutions. From a macroeconomic viewpoint, the actual no more than two ways: firstly, to seek renewable energy to replace the existing natural resources; Second, find ways to improve the current use of energy efficiency and conservation measures taken. The former includes water, wind and solar energy, particularly solar energy, particularly in recent years by the people's attention. According to statistics, shine on Earth one hour of solar energy that is equivalent to about 1 year the world consumes energy. Utilization of solar energy the most effective way is through the use of solar cells made of silicon materials. Silicon solar cell after 50 years of development have made great progress, and its conversion efficiency by approximately 10-fold, reaching 11% to 19% cost reduction of 100 times over 20 years of life, in 2008 the world market scale 180 billion. Gartner market research firm predicts that 2013 will be an annual rate of 17% of rapid growth, will reach 34 billion U.S. dollars, and its share of world electricity generation is also only a few percent of total generating capacity, prospects are promising broad, bright. The second solution is efficiency and conservation, are involved in all aspects of the existing energy available, the following is presented separately. It is noteworthy that, regardless of efficiency or developing renewable energy, energy conservation are inseparable from the innovative use of semiconductor technology. According to foreign media reports, the 30 years since 1978, the semiconductor technology has improved the efficiency of the automobile 40%, flying aircraft increased 120%, 340% improved lighting, computer system is raised 3 times.
