Watch the history of waste-to-energy power plants in the United States

A waste-to-energy (WTE) plant is a facility that burns municipal solid waste (MSW) in boilers to produce steam and then electricity. Sixty WTE plants were operating in the United States in 2022, with a total generating capacity of 2,051 megawatts (MW) that supplied less than one percent of the country’s electricity.1

Throughout the country’s history, the cheapest and easiest way to deal with garbage was to bury it. These became known as landfills, and all landfills eventually reached capacity. From 1979 to 1991, the United States exhausted more than two-thirds of its landfills. Between 1983 and 1987, for example, New York closed 200 of its 500 landfills.2 Space for new landfills grew increasingly scarce in the densely populated urban areas of the East Coast. From Massachusetts to Maryland, municipalities turned to WTE plants to deal with their garbage problems. A modest building boom ensued from the early 1980s to the early 1990s. By the early 1990s, the United States combusted more than 15 percent of all MSW.3

WTE facilities are frequently classified as renewable sources of electricity because the fuel supply (garbage) is continuous and reliable, and because some of the fuel is biogenic (paper, yard trimmings, food waste, textiles, and some containers and packaging). But the waste stream also includes non-biogenic materials such as plastics, metals, and glass, suggesting that the “renewable” moniker is misleading. Like their fossil fuel counterparts, WTE plants create significant air, water, and solid wastes that require expensive pollution control equipment.

Very few WTE facilities have been built in the United States since the mid-1990s due to community opposition, high cost compared to other sources of electricity, and the increased emphasis in many communities on waste reduction, recycling, and composting.

Recent Data Stories

What are the connections among fuel poverty, time poverty, and gender equity?

Access to clean cooking fuels is crucial for gender equity and poverty alleviation. Currently, billions of people lack safe and affordable energy sources for cooking. Women and girls bear a disproportionate burden in collecting and processing polluting fuels, affecting their well-being and opportunities. Clean cooking energy reduces cooking time, allowing women to engage in other activities like childcare, work, and household chores.

What is the ‘diesel discount’ and does it matter?

Road transport relies heavily on gasoline and diesel, influenced by government policies that often favor diesel for its efficiency. However, diesel produces more pollution, and the tax revenues it generates complicate change. The debate now centers on speeding up the transition to electric transportation to combat greenhouse gas emissions while balancing historical preferences with environmental concerns.

How does public finance support energy?

The global energy system encompasses diverse infrastructure requiring extensive investment, with USD 2.8 trillion spent in 2023. Public finance significantly supports energy projects, where fossil fuels received 56% of funding from 2013 to 2022. Clean energy finance increased until 2021, highlighting varying regional priorities and the dominance of large projects in funding distribution.

Where are people most exposed to particulate matter?

Airborne particulate matter (PM2.5) comprises tiny particles that pose significant health risks, including heart disease and lung cancer. Major sources include natural events and human activities, with notable geographic variations. Reductions in PM2.5 levels have been observed in affluent regions, but exposure remains high in countries like China and India, impacting public health.

What renewable fuels have the largest climate benefit?

Approximately 91% of transportation energy globally comes from petroleum fuels, creating 29% of US and 20% of global greenhouse gas emissions. Biofuels offer potential emission reductions but raise land use concerns. Ethanol's carbon emissions have decreased, and ongoing research aims to further reduce them. Government support and investments are driving biofuel expansion.

What is nuclear power uprating and why is it important?

Nuclear power in the US has steadily contributed 19% of electricity since 1990, mainly through uprates. These uprates, approved by the NRC, have boosted capacity by 24,080 MWt or 8030 MWe, equivalent to over 7 new plant units. Most uprates range from 0-5%.

Our mission

Visualizing Energy communicates facts on the link between sustainable energy and human well-being to decision-makers, media, companies, advocates, educators, and the public.

Who we are

Visualizing Energy is an independent and neutral university-based research and communication organization.

What we do

We knit data analysis, visualizations, and the written word into stories that reveal how our energy system can be transformed to reduce inequity, steer humanity from climate disaster, improve health and other social outcomes, and lead to healthier natural systems. We address the energy system itself (sources, conversion, end use), economics (prices, investment, market failures), social outcomes (well-being, energy poverty, and climate justice), and environmental change (climate, pollution, and land and water use).

How are we different

The internet is awash in information about energy, climate change, and health impacts of pollution. But society is deficient in a shared understanding of how our energy system must change. One reason for that is that information is siloed by technology, policy, and disciplines. We use the unique role of energy in human affairs and natural systems as the unifying principle behind compelling, data-driven stories that point to solutions that are feasible, affordable, and equitable. We are interdisciplinary and collaborative, working with diverse teams and perspectives that span the broad energy landscape.

Open access

Visualizing Energy aims to accelerate a sustainable energy transition by deploying a more equitable system of knowledge. To that end, all the data, visualizations, and original text are freely available to all users. We license all our content under the Creative Commons BY license. Users have permission to use, distribute, and reproduce the data, visualizations, and articles provided the source and authors are credited.

Transparency

We heavily rely on data that someone else produced. All the data in Visualizing Energy is attributed to its original source so that the user can independently judge its accuracy and reliability. We describe all major modifications that we make to data.
