地球每小时从太阳获得的能量比地球本身一年所耗能量还要多。然而作为能源来说,地表所接受的太阳热密度很低,而且是间断的,所以想要把这些热能收集起来,转换成有用的能量贮存起来,目前在技术上还存在不少问题。近8年,世界上许多国家的政府、大学和民办企业,都对太阳能的有效管理和 Every hour the Earth receives energy from the sun more than the Earth itself consumes. However, as the energy source, the solar heat density on the surface is very low and intermittent, so it is technically still problematic to collect these heat energy and convert it into useful energy for storage. In the past eight years, governments, universities and private-owned enterprises in many countries of the world have made effective management of solar energy and
