Effects of Fuel Costs on New Electricity Generators in the United States
研究了天然气燃料成本如何影响美国新建发电机组选择天然气、风能或太阳能及其装机容量，发现燃料成本上升显著增加可再生能源比例，并模拟了碳税情景下的减排效果。
We estimate the effect of the natural gas fuel cost on the choices for a new power generator; the energy source of gas, wind, or solar; and its capacity. Higher fuel costs increase odds of more renewable capacity, as opposed to gas, with large, significant effects for both wind and solar. As the United States has yet to implement nationwide carbon policies, we use fuel cost to proxy for a carbon tax. Our scenarios of $10–$50 per ton of carbon dioxide reduce emissions from new generators by 22%–47%, equivalent to 2%–4% of total electricity emissions.
