Representatives Waxman of California and Markey of Massachusetts proposed a law to limit greenhouse gas emissions from electricity generation and require electricity producers to generate a minimum percentage of power using renewable fuels, with some rights to emit to be auctioned. The Congressional Budget Office estimated that the government would receive $846 billion from auctions and would spend $821 billion on incentive programs and compensation for higher energy prices. Electricity producers would spend $208 million a year to comply with the new rules. (Think of these dollar amounts as dollars' worth of other goods and services.) Is the $846 billion that electricity producers pay for the right to emit greenhouse gasses part of the opportunity cost of producing electricity?
