一份来自国际能源机构的报告显示,太阳能发电是一个非常有潜力的行业，到2050年,太阳能发电将占据全球能源总数的25%。
报告的内容包括光伏技术和集中太阳能技术,这两项技术在世界各地越来越普遍,特别是提到怎么有效地供给家庭用电时。
光伏技术和集中太阳能技术相结合,大大提高了能源的安全性,到2050年之前二氧化碳的排放量将每年降低60亿吨。总而言之，这两项太阳能技术到2005年可产生9000兆瓦的能量。
在阳光充足和天气晴朗的地区,比较适合集中太阳能技术,而在电网比较分散和比较偏远的地区则比较适合光伏发电。
随着太阳能行业的发展,风能、地热能、生物能等其他方面也在为世界能源做出越来越多的贡献。
A recent report from the International Energy Agency is offering a glimpse of the future growth potential that solar power offers.
According to the IEA, solar-generated electricity could account for as much as 25 percent of global production by 2050. This week, the energy organization released a report that includes roadmaps for both photovoltaic technology and concentrating solar power. Both of these options are becoming increasingly common around the world, especially when it comes to utility-scale projects that can power thousands of homes.
"The combination of solar photovoltaics and concentrating solar power offers considerable prospects for enhancing energy security while reducing energy-related CO2 emissions by almost six billion tonnes per year by 2050," said Nobuo Tanaka, executive director of the IEA.
In total, both solar technologies could generate 9,000 terawatt hours of energy by 2050. Areas with the sunniest and clearest skies are said to be well suited for concentrating solar projects, while photovoltaic technology is cited for its potential for on-grid distribution and off-grid production in more remote areas.
Along with solar, other industries such as wind, geothermal and biomass are also seen in many quarters as being poised to make growing contributions to the world's energy needs.
