Nuclear energy plays a vital role in protecting the environment and advancing deep decarbonization. As the largest source of clean electricity in the United States, it already prevents more than 470 million metric tons of carbon dioxide emissions each year—equivalent to removing over 100 million cars from the road. At a time when we need rapid and sustained emissions reductions, nuclear power offers a proven, scalable solution.
Reliable, Carbon-Free Power Around the Clock
One of nuclear energy’s greatest environmental benefits is its ability to generate carbon-free electricity around the clock. Unlike some renewable sources that depend on weather conditions, nuclear plants operate 24/7, providing consistent, reliable power without emitting greenhouse gases. This reliability makes nuclear an essential partner to wind, solar, and other renewables in building a stable, low-carbon energy grid.
Cleaner Air Benefits
Beyond carbon emissions, nuclear energy also helps keep the air clean. Nuclear plants do not produce harmful pollutants such as nitrogen oxides (NOx), sulfur dioxide(SO₂), particulate matter, or mercury—substances that contribute to smog, acid rain, and serious health issues like asthma, heart disease, and lung cancer. By avoiding these emissions, nuclear energy supports healthier communities.
Low Environmental Impact Across Its Lifecycle
Environmental impact goes beyond what’s released into the air. Life cycle assessments—tools used to evaluate the full environmental footprint of energy sources—consistently show that nuclear power has among the lowest overall impacts per unit of electricity produced. From mining and construction to operation and waste management, nuclear energy performs comparably to wind and solar across key measures like land use, resource efficiency, and human health effects. Notably, nuclear plants require far less land than other clean energy sources, producing large amounts of electricity from a relatively small footprint.
Safe and Responsible Waste Management
Nuclear energy also contributes to environmental protection through responsible waste management. Used nuclear fuel is safely contained and carefully regulated, ensuring it does not enter the environment. This level of control stands in contrast to the widespread emissions and waste associated with fossil fuels.
A Critical Tool for a Sustainable Future
Nuclear energy offers a powerful combination of clean air benefits and low environmental impact. Maintaining our existing plants and investing in advanced nuclear technologies will be essential to achieving a cleaner, healthier New York.
