目前,世界各国对非传统可再生能源的利用越来越重视。其特征之一是某些国家对这一领域的科学研究与试验设计拨款规模逐年增加。特征之二是各种非传统再生能源优选顺序发生改变。目前占第一位的是太阳能、第二是生物(沼气)动力,第三则是地热动力。 At present, all countries in the world pay more and more attention to the utilization of non-traditional renewable energy. One of its characteristics is that in some countries, the scale of scientific research and experimental design appropriation in this area has been increasing year by year. The second feature is that the order of preference for various non-traditional renewable energy sources changes. Currently the first one is solar energy, the second is bio (biogas) power, the third is geothermal power.
