Breakthrough Energy Ventures LLC

Breakthrough Energy is the umbrella name of several organizations, founded by Bill Gates in 2015, that aim to accelerate innovation in sustainable energy and in other technologies to reduce greenhouse gas emissions. It has been investing in a variety of startup companies which were attempting to commercialize new concepts such as nuclear fusion, large-capacity batteries to store renewable energy, and microbe-generated biofuels. In 2025, strategy shifted away from public policy towards supporting clean energy technology alone, as the Second Trump administration has been promoting fossil fuels and dissolved programs addressing climate change.
