But both strategies are probably correct. Most studies show that deep de-carbonization of the world economy from now to mid-century, a time horizon mandated by environmental realities, will require that all low-carbon options – including greater efficiency and renewables –&#160;be scaled up massively.
哪条新道路更明智——法国的核电还是德国的太阳能——远未可知。但两种战略可能都不错。大部分研究表明，行现在开始到本世纪中叶，世界将经历深刻的去碳化，这个时间长度是由环境现实决定的。去碳化要求所有低碳选择——包括提高能源效率和可再生能源——都要大幅扩大规模。
