能源革命必定是核能革命

牛津——世界各地的示威者都要求为了保护环境而减少碳基能源的供应。然而,在德国,旨在满足这些需求的能源转型政策却未能减少二氧化碳排放。问题的很大一部分在于,为了回应长期以来的反核情绪,政策制定者计划逐步淘汰核能,同时投资风能和太阳能等可再生能源。

通过学习驾驭风、水和火(燃烧树叶和木头)的力量——基本上就是我们今天所说的“可再生能源”,我们早期的祖先掌握了自然。但是他们所掌握的能源很弱,只有在天气允许的情况下才能使用。因此,他们的生活水平很低,寿命很短,人口依然很少。

随着工业革命的到来,这一切都改变了。人类学会了通过燃烧煤以及后来的石油和天然气来为发动机提供动力。衡量燃料效用的一个标准是它的能量密度,即每千克(2.2磅)的电力单位数(kWh)。化石燃料的能量密度为每千克1-7千瓦时,是可再生能源的1000倍,无论天气如何,都可以随时随地被利用。

    The Return of Fiscal Policy

    Jim O'Neill

    With interest rates at record lows and global growth set to continue decelerating, there has rarely been a better time for governments to invest in infrastructure and other sources of long-term productivity growth. The only question is whether policymakers in Germany and elsewhere will seize the opportunity now staring them in the face.
