With such low wind and solar costs in Colorado, the question became: how can fossil plants that raise the cost of service to consumers be shut down or retired in favor of new wind and solar to support, rather than oppose the utility’s financial interests?
In 2004, Colorado voters bet on the outcome of costs dropping for wind and solar energy as they were used more — and it looks like the initiative’s promise is coming to fruition. Today, around 6,000 gigawatt hours (GWh) of generation from Colorado coal plants could be replaced with 2 gigawatts of wind while reducing costs passed onto ratepayers — without threatening reliability.
The EPA and the U.S. Transportation Department on Tuesday issued regulations that require trucks become more efficient through 2027. The final rules achieve 10 percent more carbon emission and fuel-consumption reductions than last year’s proposed rules, likely raising the price tag price for such vehicles but cutting operating costs.
