As Congressional leaders in Washington, DC remain stalled out on climate-related legislation, states are moving forward, even in conservative parts of the country. New Mexico is the latest.

The southwestern state is the latest to embrace carbon-free electricity, passing a bill that will require all electricity from public utilities to come from carbon-free sources. The bill, which passed 43-22 in New Mexico’s increasingly Democratic legislature, requires the state (now one of the country’s top oil, gas, and coal producers) to get 50% of its energy from renewables by 2030 and 80% by 2040. By 2045, it must go entirely carbon-free.

Most of the new electricity is expected to come from wind and solar sources. Opponents of the bill cast doubt on the state’s ability to move beyond fossil fuels; for example, it will require that the 847 MW San Juan Generating Station, one of the nation’s major coal plants, to close by 2022.
