Renewable energy generates electricity from naturally replenishing sources such as wind, sun, water, biomass (organic material like plants, wood and waste) or heat (geothermal energy). Unlike fossil fuels, renewable energy sources are clean and reduce carbon emissions and air pollution. Generating electricity from clean, sustainable and affordable energy sources can improve health outcomes by reducing harmful pollutants emitted by coal and natural gas plants and benefit the economy by reducing health-related costs.
Renewable energy is the fastest-growing energy source sector in the United States, increasing 42% between 2010 and 2020. In 2022, renewable energy generation in the U.S. surpassed coal for the first time. Much of the recent growth in renewable energy is driven by record-high solar and wind energy production. However, due to policy changes in 2025, the latest projections for renewable energy growth in the U.S. have decreased 50%.
Implementing state-level policies that support producers of preferred energy sources (wind and solar) can help reduce greenhouse gas emissions from the power sector. Strategies to increase renewable energy production include:
Several federal financial incentive programs for renewable energy exist, including the Renewable Electricity Production Tax Credit and the Residential Clean Energy Credit.

America’s Health Rankings builds on the work of the United Health Foundation to draw attention to public health and better understand the health of various populations. Our platform provides relevant information that policymakers, public health officials, advocates and leaders can use to effect change in their communities.
We have developed detailed analyses on the health of key populations in the country, including women and children, seniors and those who have served in the U.S. Armed Forces, in addition to a deep dive into health disparities across the country.
