On Monday June 2nd, the EPA proposed its Clean Power Plan that is intended to cut U.S. carbon emissions from existing power plants by 30 percent (compared with 2005 emissions) by 2030. The reductions in carbon pollution that will need to be implemented will be different for each state given that each state utilizes a different fuel mix for electricity generation and may already be incorporating low-carbon technologies at existing power plants. According to the EPA, “states can choose the right mix of generation using diverse fuels, energy efficiency and demand-side management to meet the goals and their own needs.” You can view the June 2nd press release here.
As a teacher, this proposed rule provides a great opportunity for your students to examine the current energy sources used to generate electricity in NC and then to critically assess the various strategies that could be used to reduce carbon pollution by the electricity sector in NC. Janet McCabe, head of EPA’s Office of Air and Radiation, in her post titled Understanding State Goals Under the Clean Power Plan on the EPA Connect Blog, summarized the four measures the EPA identified that are “technically sound, affordable, and that result in significant reductions in carbon intensity. They are:
1) improving efficiency at existing coal-fired power plants,
2) increasing utilization of existing natural gas fired power plants,
3) expanding the use of wind, solar, or other low- or zero-emitting alternatives, and
4) increasing energy efficiency in homes and businesses.”
According to data from the US Energy Information Agency (EIA), in 2012 NC ranked 15th nationally in terms of its contribution of carbon dioxide emissions from the electricity sector.
The EPA’s Clean Power Plan interactive map tool enables users to click on a state to learn more about EPA’s carbon reduction goals for that state and to learn about the fossil fuel fired power plants covered by the proposed plan. The EPA has proposed that North Carolina lower its carbon pollution to 992 lb/MWh in 2030. North Carolina’s 2012 emission rate was 1,646 pounds/megawatt hours (lb/MWh) so this represents a 40% reduction in emissions by 2030.
You can read more about what this plan means for NC by reading the June 2, 2014 News and Observer article, EPA calls on NC power plants to reduce emission rates 40% by 2030. According to the article, which referenced Jonas Monast, director of the climate and energy program at Duke University’s Nicholas Institute for Environmental Policy Solutions and adjunct professor at the UNC School of Law, federal projections show North Carolina is already on track to see an 18 percent drop in carbon emissions by 2020, compared with 2005.
