Environmental and Energy Study Institute

What Environmental and Energy Study Institute does

The Environmental and Energy Study Institute (EESI) is an independent 501(c)(3) nonprofit organization founded in 1984 by a bipartisan Congressional caucus to provide science-based policy education on climate change, energy, and environmental issues. Headquartered at 1020 19th Street NW, Suite 400, Washington, DC (EIN: 52-1268030), EESI operates without congressional funding and is supported entirely by foundation grants and individual donations. The organization educates Members of Congress and their staff through congressional briefings, rapid readouts, webinars, and the annual Congressional Renewable Energy and Energy Efficiency EXPO and Policy Forum, while maintaining formal relationships with the House and Senate Renewable Energy and Energy Efficiency Caucuses.

EESI's product suite spans a content marketing and policy research platform built around briefings, white papers (fact sheets, issue briefs, and reports), three newsletter brands (Climate Change Solutions biweekly, EESI Impact six times per year, and COP Dispatch during UN climate summits), and the bimonthly Climate Conversation podcast currently in Season 11. Complementary programs include the Richard L. Ottinger Internship Program (three annual cohorts) and the Future Climate Leaders Scholarship ($4,000 annual awards). Technical infrastructure is conventional—website (eesi.org) with full RSS, Salesforce Marketing Cloud for email, Stripe for donations—rather than proprietary or AI-driven.

The revenue model is grant- and donation-based with no pricing model applied to end users; all publications, briefings, and podcasts are free to policymakers, media, and the public. Customer segments include U.S. Congress and Congressional staff (primary), federal and state government officials, students and young professionals, and partner nonprofit organizations. Co-hosting partnerships with NRDC, American Rivers, Alliance to Save Energy, Federation of American Scientists, Business Council for Sustainable Energy, and NASEO extend operational reach across the climate and energy ecosystem.
