Chesapeake Bay: Clarence is a strong supporter of protecting the Bay by reducing stormwater runoff and chemical pollutants, such as nitrogen and phosphorus.
Greenhouse gases: Clarence supports measures that will reduce greenhouse gases, including a repeal of the state's mined coal tax credit.
Renewable energy sources: Clarence believes the state can increase the supply of green energy to consumers, which will promote renewable sources such as wind and solar energy and create new "green" jobs.
Hydraulic fracturing: Clarence supports a moratorium on "fracking" because there are serious concerns about groundwater contamination and adverse health effects, such as cancer clusters.
Cove Point: Clarence opposes the conversion of Cove Point to a liquefied natural gas export facility because it will ultimately lead to greater pollution, more expensive domestic natural gas, and the increased demand for "fracking."
