This is a list of U.S. states and territories by carbon dioxide emissions for energy use, [1] [2] as well as per capita [3] [4] and by area. [5] The state with the highest total carbon dioxide emissions is Texas and the lowest is Vermont. The state with the highest per capita carbon dioxide emissions is Wyoming and the lowest is New York.
The Emissions & Generation Resource Integrated Database (eGRID) is a comprehensive source of data on the environmental characteristics of almost all electric power generated in the United States. eGRID is issued by the U.S. Environmental Protection Agency (EPA).
This is a list of U.S. states by total electricity generation, percent of generation that is renewable, total renewable generation, percent of total domestic renewable generation, [1] and carbon intensity in 2022. [2] The largest renewable electricity source was wind, which has exceeded hydro since 2019. [3]
Nuclear energy and renewable energy have reduced environmental costs by decreasing CO 2 emissions resulting from energy consumption. [ 42 ] There is a catastrophic risk potential if containment fails, [ 43 ] which in nuclear reactors can be brought about by overheated fuels melting and releasing large quantities of fission products into the ...
Generation by state and source. The following figures offer detail into the sources of generation used in each state. [53] Most often, natural gas is the largest source in a given state, with 22 states using it more than any other. Among renewable sources, 18 states use wind power more than any other.
As a percentage of all anthropogenic greenhouse gas emissions, carbon dioxide (CO 2) accounts for 72 percent (see Greenhouse gas), and has increased in concentration in the atmosphere from 315 parts per million (ppm) in 1958 to more than 375 ppm in 2005. [63] Emissions from energy make up more than 61.4 percent of all greenhouse gas emissions. [64]
Electricity generation has been approximately flat in the last ten years, [4] but with significant changes in composition over that time. In 2013 coal was 38.8% of generation, natural gas was 27.6%, nuclear was 19.4%, wind was 4.1%, hydro was 6.6%, and solar was 0.2%. Because of this shift, CO2 emissions have gone down by 30%. [5]
Electricity generation is the fourth highest combined source of NO x, carbon monoxide, and particulate matter in the US. [21] According to the International Energy Agency (IEA), low-carbon electricity generation needs to account for 85% of global electrical output by 2040 in order to ward off the worst effects of climate change.
