Pronuclear Advocates & Allies

Pronuclear advocacy has been growing rapidly. Today, many more groups are working worldwide to save existing nuclear, reform clean energy policies that exclude nuclear and educate the public about the benefits of nuclear. This is a reflection of growing support for the use of nuclear power as a solution to climate change.

The pronuclear movement consists of mostly smaller, independent teams that do grassroots organizing around a theme, such as working to prevent the closure of a local nuclear power plant. Fortunately, many of these groups are interconnected yielding suprisingly effective coordination when it matters. Many also have broader goals, such as the Climate Coalition, which aims to strengthen the climate movement overall by uniting climate activists of all stripes in support of an “all-of-the-above” nuclear-inclusive approach to clean energy.

For those who want to support nuclear power in addition to (or in lieu of) investing in next-generation technologies through Nucleation Capital, we provide the following recommendations: 

       1) Stop sending donations to the Sierra Club, NRDC,, Friends of the Earth, League of Conservation Voters, or Greenpeace. All of them know we need nuclear and none have had the courage and integrity to publicly express support of nuclear.

      2) If you have been a member or supporter of an environmental group, write to let them know you will support them again when they change their position and publicly support the use of nuclear power to more rapidly and reliably reduce carbon emissions.  

      3) Throw your support behind one or more of the pronuclear nonprofits that are working hard to save existing power plants and to advocate for nuclear power. We have curated the following lists to help you find organizations or individuals to support.

Nucleation’s Top 5 Pronuclear Organizations


Californians for Green Nuclear Power, led by Dr. Gene Nelson, has  been a driving force for political accountability and responsible energy decision-making in California. Shedding light on sweetheart backroom political deals being cut by Governor Jerry Brown that were contrary to the public interest, CGNP filed suits and/or petitioned to become a party to CPUC and FERC proceedings. CGNP’s work as an intervenor has been instrumental in helping to save Diablo Canyon. CGNP’s in depth research continues to pose obstacles to efforts to overturn the California legislature’s extension approval are being filed. (Donations can be mailed to CGNP at 1375 East Grand Ave Ste 103 #523, Arroyo Grande, CA 93420-2421.)


Mothers for Nuclear was created on Earth Day 2016 by the power team of San Luis Obispo-based Heather Hoff and Kristin Zaitz, two moms to better represent the voices of women and mothers in support of Diablo Canyon and nuclear energy in general. Coordination with Californians for Green Nuclear Power, Save Clean Energy and many other groups enabled Governor Newsom to respond to strong public pressure to save Diablo Canyon when appealing to the California Legislature. Progressive women remain predominantly opposed to nuclear power, but Mothers for Nuclear have begun to rebuild the social norm of women being pronuclear. (Donations can be made online. EIN: 81-3349003)


Generation Atomic was created by Millenial Eric Meyers to represent the voices of younger generations and empower them to express support for nuclear in every type of venue and forum where discussions of how solve climate change is happening. The group creates fun, engaging, public actions in an effort to safeguard our future by championing the cause for nuclear energy. Not only do they use research, communication and relationship-building to advocate for nuclear, their actions typically involve dancing, singing, inflatable costumes and a high degree of humor to inspire, empower and engage youth and keep those who are anti-nuclear or who just wish to ignore the issue off-balance. Operatic nuclear arias, anyone? (Donations can be made online. EIN: 81-4500446)


Thorium Energy Alliance was started in 2006 by John Kutsch to bring together scientists and energy experts who believe that thorium should be used as nuclear fuel. Thorium is far more abundant and less radioactive than uranium, yet was rejected early on in the history of nuclear development, despite evidence that thorium could power a molten salt reactor safely and be highly cost-effective. TEA has worked to protect nuclear’s abundant innovation history as well as raise awareness about abundant but wasted materials like thorium. TEA has served as a central organizing entity, advocating for alternative reactor designs within broader discussions of how to expand access to nuclear power. John Kutsch has provided guidance, support and inspiration for many young activists, which history was beautifully captured in the Frankie Fenton documentary film “Atomic Hope.” (Donations of cash or cars can be made online.)


Climate Coalition was founded in 2016 by Valerie Gardner and a group of mostly Silicon Valley-based, technology-oriented climate activists who recognized how much stronger the climate movement would be if those who supported renewables and those who supported nuclear were aligned and worked together. While individuals may have preferences over the type of clean energy that they chose to work for or invest in, opposing other types of clean energy is self-defeating activity that only slows down to global effort to convert to 100% clean energy systems everywhere. Sadly, many mainstream environmentalists oppose nuclear power, even though nuclear provides baseload power stabilization to the grid, something badly needed by grids with high levels of renewables. So long as there is fighting within the climate movement, demand for and investment in fossil fuels will remain strong. Which is why the Climate Coalition is launching its Unite Against Emissions campaign in 2024.

There are many other worthy groups, so we’ve listed more of them below, followed by influencers, authors, podcasters and artists (alphabetically)
