| 英文摘要: | Fossil fuels are crucial, though dirty, drivers of our economy. They produce 82% of all energy consumed in the U.S., but they pollute our air and water, contribute to global climate change, and increase our dependence on foreign energy sources. Yet relying on renewable energy sources instead could be costly and disruptive for the U.S. economy. Thus a critical question arises: how do we reduce fossil fuel use in the most cost-effective way?
We can cut fossil fuel use by reducing the amount of energy necessary to do things – by improving energy efficiency. Estimates of the expected savings from energy efficiency rely on detailed ex ante calculations, which typically predict massive savings. Yet reality has been far different, with the energy saving activities we observe far lower than expected. This disparity between the levels of investment in energy efficiency that appears to be cost effective based on ex-ante predictions and the levels actually observed is known as the energy efficiency "gap."
This gap matters. Encouraging investments in cost-effective energy efficiency improvements is a politically acceptable way to mitigate global climate change and reduce dependence on foreign fuel. Despite the amount of money spent on energy efficiency programs, the true size of the efficiency gap is the subject of intense debate (See, e.g., Allcott and Greenstone, 2012). Are consumers and businesses bypassing profitable opportunities to reduce their energy consumption? Are current energy efficiency programs in the U.S. providing the biggest bang per energy efficiency buck? |
