The Administration said the United States will submit its 2025 target to the Framework Convention on ClimateChange as an “Intended Nationally Determined Contribution” no later than the first quarter of 2015. This CCUS project with Enhanced Water Recovery will eventually inject about 1 million tons of CO2 and create approximately 1.4
The power sector has become less carbon-intensive as natural gas-fired generation displaced coal-fired and petroleum-fired generation and as the noncarbon sources of electricity generation—especially renewables such as wind and solar—have grown. In 2005, noncarbon sources accounted for 28% of the US electricity mix.
