+1 for Wallace. Basically everything in that collection and Consider the Lobster is worth reading. Absolutely unrelated, but I'd recommend Vaclav Smil in general - Energy in Nature and Society and Energy and Civilization are two I've read and enjoyed. A bit dry as reading material, but well-worth for his energetic perspective on human and biological systems.
…doubled with China's sudden rise. We'll probably want 50% - 100% more by 2050 as India and Nigeria develop. 0.2 TW continuous per year (the optimistic figure) growth in solar is not fast enough, IMHO. 1. Energy in Nature and Society, Smil V.
…the PDF right, it uses about 12 PJ per tonne of iron produced. Best current practice with coking coal is about 15 GJ per tonne.[1] So just a little energy efficiency improvement required. 1. Smil, V. Energy In Nature And Society 2008, p. 283 of paperback.
…milk, red meat and a few other low-value-add bio-materials in order to buy everything else. Land is valuable to the country as a whole for its export revenue. I had also been re-reading Vaclav Smil's Energy in Nature and Society, in which he says the areal (per square meter) power intensity of PV production is approximately the same as the areal power consumption of cities, so we need the same order of magnitude of land that…
Yeah, my unit of analysis is the decade, sorry. Been reading Vaclav Smil too much (Energy in Nature and Society; Grand Transitions). There was a news item on the BBC recently about battery swap being used by taxi firms in "second tier" Chinese cities (so, only 5M - 15M inhabitants). That's how it starts: large…
给华莱士+1。那部选集里的内容，还有《考虑龙虾》，基本都值得一读。完全扯个题外话，不过我个人很推荐瓦茨拉夫·斯米尔——《自然与社会中的能量》和《能源与文明》这两本我读过，都很喜欢。作为读物稍微有点枯燥，但他从能量角度审视人类和生物系统的视角非常值得一读。

……加上中国的迅速崛起直接翻了一倍。随着印度和尼日利亚的发展，到2050年我们可能需要再多出50%到100%。在我看来，太阳能每年持续增长0.2 TW（这还是乐观估计）根本不够快。1. 斯米尔《自然与社会中的能量》。

……如果我没看错PDF的话，每生产一吨铁大约消耗12 PJ。目前用焦煤的最佳实践大约是每吨15 GJ左右。[1] 所以只需要稍微提高一点能源效率就行。1. 斯米尔，《自然与社会中的能量》2008年版，平装本第283页。

……牛奶、红肉和其他几种低附加值的生物原料，以此来换取其他所有物资。土地靠出口创收对整个国家至关重要。我之前也在重温瓦茨拉夫·斯米尔的《自然与社会中的能量》，他在书里提到光伏发电的面功率密度（每平方米）与城市的面积用电功率大致相同，因此我们需要的土地规模……

哈哈，我的分析时间尺度是以十年为单位的，抱歉。最近瓦茨拉夫·斯米尔读太多了（《自然与社会中的能量》、《大转型》）。BBC最近有条新闻，说中国“二线”城市（也就是人口‘只有’500万到1500万的城市）的出租车公司开始采用换电模式了。事情往往就是这样开始的：大型……
