清洁能源,哪个更给力?

Which kind of clean energy is more useful?

日本核危机的发生,导致了世界对核能的谨慎与再认识。德国放弃核能,就是若干例证之一。但是,从全球范围来看,目前世界电力供应的13%-15%来自核电。作为清洁能源的重要组成部分,核能危机无疑对清洁能源的推广和使用造成了不利的影响。那么,利用什么能源来代替核能?已经成为业界的热点议题。据统计,绝大多数国际大石油公司已经涉足可再生能源和新能源领域,正在逐步实现由石油公司向能源公司的转变。目前,大型跨国石油石化公司涉足的可再生能源和新能源领域主要有太阳能光伏、风能、生物质能、氢能和燃料电池等。那么,这些可再生能源,到底哪一个能担当起未来经济发展的能源重任?抑或除此之外,尚有更好的选择?

Nuclear risk occurs in Japan caused renew cognition to nuclear energy of the world. German discarding is one of the examples. But 13%-15% electricity supply is from nuclear energy in the world. As an important part of clean energies, nucleus risks effect bad influence to the generalization and use of clean energies. So it is a hot topic that what can replace the nuclear energy. According to statistics, most of major oil companies stepped into the renewable energy sources and new energy, including solar energy, photovoltaic, wind energy, biomass energy, hydrogen energy and fuel cell. They are transforming from oil companies to energy companies. So, which kind of renewable energy will undertake the heavy responsibility of future society development？ Or, is there another better choice？
