The document proposes the Energy Data Initiative (EDI), which aims to accelerate clean energy innovation through opening up energy data. It discusses how opening data can fuel innovation by enabling new companies and products. The EDI will generate and open energy data to create an energy data ecosystem. Innovators will then be able to leverage open data to accelerate clean energy development while protecting privacy and confidentiality. A "playbook" is provided outlining strategies for implementing open data initiatives through releasing new datasets, community engagement, workshops, and events to highlight private sector uses of open data.
