  • How to shut down 93% of coal without building new plants or reducing power supply

    Two interesting observations: 50% of U.S. power generation (in MWh) comes from coal, while only 20% comes from natural gas. 32% of total U.S. power generation capacity (in MW) is coal-fired, while 42% is gas-fired. When it runs, the natural gas fleet emits just 50% of the CO2 of the coal fleet, which raises a […]

  • So how much would a $20/ton carbon price really cost?

  • Cap & trade: Carbon tax or wealth transfer?

The ubiquity of this faith makes clear that the Smart People who write, talk, and vote about CO2 policy don’t really understand the issues. A quick discussion, and then some math to clarify. There are two core problems […]
