Which climate-focused organization did Bill Gates launch in 2015 to support clean-energy innovation?

Bill Gates launched Breakthrough Energy in 2015 to support clean-energy innovation.

The organization was created to encourage investment and development in technologies that could reduce greenhouse-gas emissions. Its work has included efforts involving electricity, transportation, agriculture, manufacturing, and buildings.

Breakthrough Energy is associated with a network of initiatives rather than being only one investment fund. These initiatives include venture investment, policy advocacy, research support, and partnerships intended to move emerging technologies toward commercial scale.

Its creation followed Gates’s growing public focus on climate change and energy systems. It is separate from the Bill & Melinda Gates Foundation, whose central work has focused on global health, development, and other philanthropic priorities.
