The Los Angeles Times reported that the state of California had acted to limit use of coal power. The California Energy Commission on Wednesday imposed new rules that effectively forbid the Los Angeles Department of Water and Power and all other municipal utilities in the state from signing new contracts with coal-fired power plants.
California has largely phased out coal-fired generators within its borders, but the state still buys about 20% of its electricity from coal-fueled power plants in other states.
The maximum emissions allowed under the new rules are 1,100 pounds of carbon dioxide per megawatt hour of electricity. This rule would, in effect, require coal-fired power plants to use sequestration technology that would pipe carbon dioxide into underground repositories in order to keep selling power to California.
This is one way to make power plants minimize their CO2 emissions. A rather drastic step that could not be carried out nationwide. I would be in favor of a law that would require all new plants to sequester their CO2 and existing plants to employ sequestration over a period of years. California gets most of their power from other sources and the impact of this rule will be to encourage more renewable power generation which would not be practical in other parts of the country that, on the average, get 50% of their electricity from coal power plants.
