Maryland's strategy has been to mandate forward migration, currently 20 percent renewables by 2022. We know the results will be unfortunate because Ontario Canada has already been there. Over the past decade or so, Ontario has reduced power system carbon emissions by 80 percent to from 1990 levels. But all is not well in Ontario.
A low-risk path to sustainable Maryland electricity
In May, Gov. Larry Hogan vetoed Maryland's Clean Energy Jobs Act, which accelerates the state's Renewable Portfolio Standard from 20 percent by 2022 to 25 percent by 2020. This is a big bill; the total cost of installing enough wind and solar to deliver 25 percent of Maryland's electric power approximates $12 billion. As Ontario is discovering, the risk is underutilized or stranded assets. A wise General Assembly would let that veto stand and then reevaluate clean energy choices after a thorough
While their achievement is unprecedented, it was not well planned. Ontario learned that while wind and solar work well on high carbon systems, intermittency inhibits the ability to reach a zero-emission system. Ontario electricity prices increased by 70 percent, industry is leaving, and politicians are losing their jobs.
