新能源特点

       1、资源丰富,普遍具备可再生特性,可供人类永续利用;比如,陆上估计可开发利用的风力资源为253GW, 而截止2003年只有0.57GW被开发利用,预计到2010年可以利用的达到4GW, 到2020年到20GW,而太阳能光伏并网和离网应用量预计到2020年可以从的0.03GW增加1至2个GW。
       2、能量密度低,开发利用需要较大空间;
       3、不含碳或含碳量很少,对环境影响小;
       4、分布广,有利于小规模分散利用;
       5、间断式供应,波动性大,对持续供能不利;
       6、除水电外,可再生能源的开发利用成本较化石能源高。
