国际能源机构预测,世界能源消费2002年至2030年将增加60%。而根据预测,到2050年地球人口将增长40%,达到90亿。因此,世界对能源的需求必然还会大幅增加。这就要求科学家必须从提高传统能源的利用率以及开发新能源等方面做出更多努力。从新能源的利用与发展趋势看,风能、太阳能和生物质能发展最快,产业前景最好,其开发利用增长率远高于传统能源。 The International Energy Agency predicts that world energy consumption will increase by 60% between 2002 and 2030. According to the forecast, the population of the earth will increase by 40% to 9 billion by 2050. Therefore, the world’s demand for energy will inevitably increase substantially. This requires that scientists must make greater efforts to improve the utilization of traditional energy resources and develop new energy sources. From the perspective of the utilization and development of new energy sources, wind energy, solar energy and biomass energy are the fastest growing and the industry has the best prospects. The growth rate of its development and utilization is much higher than that of traditional energy sources.
