Measuring the Environmental Benefits of Wind-Generated Electricity
利用德克萨斯州电网中风力发电的随机性，量化了风电替代化石燃料发电所减少的排放量，发现只有在污染社会成本较高时，减排价值才超过补贴成本。
Production subsidies for renewable energy, such as solar or wind power, are rationalized by their environmental benefits. Subsidizing these projects allows clean, renewable technologies to produce electricity that otherwise would have been produced by dirtier, fossil-fuel power plants. In this paper, I quantify the emissions offset by wind power for a large electricity grid in Texas using the randomness inherent in wind power availability. When accounting for dynamics in the production process, the results indicate that only for high estimates of the social costs of pollution does the value of emissions offset by wind power exceed cost of renewable energy subsidies.
