What are carbon emissions?

"Carbon emissions" is a shorthand way of referring to carbon dioxide (CO2) released into the atmosphere. CO2 is the primary human-made greenhouse gas; greenhouse gases are associated with climate change. In general, CO2 emissions are released from burning fuels and other processes.

Try out our new tool that calculates your carbon score or the amount of CO2 emissions associated with the electricity you purchase from Duke Energy. The tool also displays your grid generation mix based on the fuel sources used to generate the electricity for your home over the last year.

Renewable and Carbon-Free Sources

Renewable energy sources are naturally replenishing resources that produce no- or low-carbon emissions. They can be generated from a number of different sources, some more familiar than others. As the technologies that help us harvest this clean power advance, they will likely become more affordable and visible.

Carbon Emissions Sources, aka Fossil Fuels

We call crude oil and petroleum, natural gas and coal “fossil fuels” because they are mixtures of hydrocarbons that formed from the remains of plants and animals. When fossil fuels are combusted (burned), oxygen in the air combines with carbon in the fuel to form CO2. This reaction releases heat, which we use for energy.

What is Duke Energy doing?

As we journey down the road to net-zero emissions, Duke Energy is demonstrating our commitment to renewable energy in many ways and many places.

Over the next decade, Duke Energy will make targeted investments in solar power plants, battery storage technology, community solar programs, wind energy and a modernized power grid to integrate renewables – all to help meet customers’ needs for cleaner, diverse, reliable energy solutions.

Planet-friendly energy for a cleaner tomorrow

There's a lot more to renewable energy than solar panels and wind turbines. We're here to help you gain a better understanding of renewables and offer ways to participate in the transition to cleaner energy sources.
*Duke Energy’s subsidiary electric utilities generate power from solar, hydroelectric and biomass (including waste to energy) resources, but do not always retain all of the environmental claims, including renewable energy certificates (RECs), related to such generation. The RECs and other environmental claims associated with such generation may be used to meet statutory or regulatory compliance obligations (on behalf of the respective electric utility and certain wholesale customers), assigned to customers pursuant to retail programs or sold/traded via bilateral commercial agreements.
