基于净能量的气候约束可持续能源转型分析
A Net Energy-based Analysis for a Climate-constrained Sustainable Energy Transition
摘要：
从化石能源经济向可再生能源经济的转变是由气候变化和资源枯竭的双重挑战推动的。建设可再生能源基础设施需要预先进行能源投资，从社会可用的净能源中扣除。这一投资取决于向可再生能源过渡的需要，以足够快的速度避免气候变化的最坏后果，同时保持足够的净能源流量，以维持世界经济和人口。我们表明，一个可行的过渡途径需要在可再生能源的投资率应加快约一个数量级，如果我们要留在IPCC的建议范围内。
英文摘要：
The transition from a fossil-based energy economy to one based on renewable energy is driven by the double challenge of climate change and resource depletion. Building a renewable energy infrastructure requires an upfront energy investment that subtracts from the net energy available to society. This investment is determined by the need to transition to renewable energy fast enough to stave off the worst consequences of climate change and, at the same time, maintain a sufficient net energy flow to sustain the world's economy and population. We show that a feasible transition pathway requires that the rate of investment in renewable energy should accelerate approximately by an order of magnitude if we are to stay within the range of IPCC recommendations.
