近几年,可再生能源领域的开发已成为发达国家和新兴经济体国家的优先选择,许多国家逐渐认识到只有依靠低碳和具有成本竞争力的新能源、再生资源,才能应对诸如全球气候变暖问题、能源安全问题等一系列新的重大挑战。目前,风力发电、光伏太阳能发电已成为能源供应领域的一个重要渠道。仅2011年上半年,全球风力发电产能就提高了9.3%,从2000年开始光伏太阳能发电能力每年增长40%。相关产业已经获得许多国家的政府补 In recent years, the development of renewable energy has become a priority for developed and emerging economies. Many countries are gradually realizing that only by relying on low-carbon and cost-competitive new and renewable resources can they cope with problems such as global climate change Warm issues, energy security issues and a series of major new challenges. At present, wind power generation and photovoltaic solar power generation have become an important channel in the energy supply field. In the first half of 2011, global wind power capacity increased by 9.3%. Since 2000, the solar photovoltaic power generation capacity has increased by 40% annually. Related industries have received government subsidies from many countries
