Help Advance Sustainable Energy by Donating to EESI Today!

“EESI is uniquely positioned to inform each successive Congress on the merits of energy and environmental legislation. There is a lot of information available to staff, but not a lot of objective information that is precisely tailored to helping busy Members and staff understand the importance and consequences of their actions.”

-Jim Turner, former Congressional staffer


“EESI is one of the most effective groups on Capitol Hill. They rely on credible scientific information to make the case for solid policy. I have worked in energy policy for many years and I turn to EESI for information because I know I can find the latest developments from the nation's experts in the field.”

-Ginty, Reviewer


“EESI is consistently an excellent organization to work with and learn from. They organize a plethora of interesting and informative briefings on the Hill, providing reliable straightforward information to stakeholders and decision makers in the energy and environment fields."

-Agatha Wein, Reviewer


“EESI keeps me updated on climate and other environmen-tal issues in Washington, with just the right amount of depth and breadth. It is absolutely unique—timely, intelli-gent and focused.”

-Gelvin S., Reviewer
