Look to energy transitions, not carbon taxes

The idea of a renewable energy transition is exciting. It opens up space to think about enhancing democracy and decolonization.

Coal can’t compete with cheaper alternatives

A study of the social cost of carbon emitted by the shrinking fleet of Texan coal plants suggests that closing more of them down would be good for the climate and public health.
