Gov. Lujan Grisham signs landmark energy bill

The Democratic governor, environmentalists and others gathered at the state capitol Friday for a signing ceremony.

The measure requires that investor-owned utilities generate at least 50 percent of their electricity from renewable sources by 2030. That jumps to 80 percent by 2040.

A 100 percent carbon-free mandate would kick in five years later. Electric co-ops that provide power to more rural areas would have until 2050 to meet that goal.

Aside from the renewable energy quotas, funds will be established to help ease the economic pains of closing the coal-fired San Juan Generating Station near Farmington.
