Southwest Energy Efficiency Project (SWEEP)

A nonprofit organization

The Southwest Energy Efficiency Project (SWEEP) is a public interest nonprofit organization advancing energy efficiency, beneficial electrification, and clean transportation in Arizona, Colorado, Nevada, New Mexico, Utah, and Wyoming.

In collaboration with utilities, state and local governments, environmental and community groups, businesses, national laboratories, federal agencies, and other energy experts, SWEEP promotes programs, policies, and funding to help mitigate climate change and its impacts, lend support to underserved and disadvantaged communities, and save people money on energy bills and transportation costs.

SWEEP was founded in 2001. Under SWEEP’s leadership, the Southwest region has made great strides in improving energy efficiency, avoiding new power plants, and reducing emissions over the past 22 years.

Funding for SWEEP is provided primarily by charitable foundations, federal agencies, business allies, and major donors.


SWEEP's mission is to ensure a healthy, equitable, and low carbon future by advancing energy efficiency, electrification, and clean transportation solutions in the southwestern region of the United States.

SWEEP accomplishes its mission through research and data analysis, policy development, advocacy, education, communications, and partnerships. We work in a number of policy forums and with many different partners: utilities, public utility commissions, state and federal agencies, local governments, businesses, nonprofit coalitions, and elected officials. We develop, advocate for, and implement non-partisan strategies that work across the political spectrum.

SWEEP staff are thought leaders, technical experts, and policy specialists who craft solutions, advocate for their adoption, and ensure their successful implementation. Efficiency is our orienting principle as we pursue cost-effective solutions to make the energy used in our buildings, industries, and transportation systems as clean and low carbon as possible, focusing first on meeting the needs of communities disadvantaged by fewer resources and historic inequities.

We envision a world where everyone has access to the clean, affordable energy and mobility they need for a high quality of life, while ensuring a healthy environment, stable climate, thriving communities, and a vibrant, sustainable economy for all.
