Subject Area
The United States (US) Clean Power Plan established state-specific carbon dioxide (CO2) emissions reduction goals for fossil fuel-fired electricity generating units (EGUs). States may achieve these goals through multiple mechanisms, including measures that can achieve equivalent CO2 reductions such as residential energy efficiency, which will have important co-benefits. Here, we develop state-resolution simulations of the economic, health, and climate benefits of increased residential insulation, considering EGUs and residential combustion. Increasing insulation to International Energy Conservation Code 2012 levels for all single-family homes in the US in 2013 would lead to annual reductions of 80 million tons of CO2 from EGUs, with annual co-benefits including 30 million tons of CO2 from residential combustion and 320 premature deaths associated with criteria pollutant emissions from both EGUs and residential combustion sources. Monetized climate and health co-benefits average 49 per ton of CO2 reduced from EGUs (range across states: 12–390). State-specific co-benefit estimates can inform development of optimal Clean Power Plan implementation strategies.

the clean power plan the United States requires power plants to reduce their emissions of carbon dioxide and who requires states to come up with strategies to do so so what are those of our study was
to build a model to understand the benefits if states embarked energy efficiency and
those benefits are twofold you can reduce carbon dioxide emissions which is the goal of the clean power plan you also
reduce other air pollutants that are emitted from power plants are such as find particular matter sulfur-dioxide
nature in oxides we want to understand
what the air quality in public health benefits would be
of those many years in our study we found a substantial benefits for both carbon dioxide emissions reductions and air quality related health benefits with a focus on increased residential
insulation we looked at how much energy will be
saved how much emissions will be reduced the health benefits if every single
family home of the U.S. increase the insulation levels to modern thresholds we
found about 80 million tons
per year of carbon dioxide would be reduced from power plants that's the equivalent of taking tens of millions of cars off the
road you'd also have 30 million fewer tons of carbon dioxide from residential fuel-burning for people were using natural gas or oil or other fuels heat their homes and there'd be 320 fewer premature and United States associated with the air pollutants emitted from the power plants so we estimate they increase residential insulation would
save about 11 billion dollars per year
across the U.S. in energy bills it would
also reviews about 2 comma decimal 9 billion
dollars in public health impacts and
3 comma decimal 8 billion dollars in greenhouse gas
emissions climate benefits so the total social benefit is pretty similar to the
direct economic benefit to people who are
installing insulation we use a
simulation model to look at how
energy consumption would change if you add insulation to existing homes in these high-performance computing platform to model homes representing buildings across the United States with an estimated emissions from of power plants in residential combustion
using models that accounted for how electricity is dispatching United States basically which power plants get knocked off 1st if you use less electricity and then we model how those emissions of fact air quality across the United States using an atmospheric model that accounts for multiple pollutants how they react in the atmosphere and helps us isolate individual pollutants from individual states with an estimated what that
did to public health and we assign monetary values to both health outcomes in greenhouse gas emissions so that we could compare to the economic savings associated with energy efficiency and so the
clean power plan focuses on carbon dioxide emission reductions from power plants but you also get a number of other benefits including carbon dioxide emission reductions from residential combustion and public health benefits from both power plants in residential combustion in all of those we call
co-benefits in this study or benefits above and beyond the target of the regulation we quantified all those and put them in monetary terms you could understand for each state where the magnitude of those benefits was and on average across the United
States we found 49 dollars per ton of C O 2 reduced of benefits that is for every time you knock off from power plants of carbon dioxide you get 49 dollars of extra benefits associate with public health as you 2 emissions residential combustion that number differed a lot across states from 12 dollars to 390 dollars emphasizing how much it's important a focus on state level benefits in 4 states to have accurate information using their decision
