Panel session on open knowledge and energy data - http://okfestival.org/open-knowledge-and-sustainability/. It’s’ in Helsinki but will be webcast. Looks likely to focus on ways to open up energy data to consumers along the lines of midata (http://www.bis.gov.uk/policies/consumer-issues/consumer-empowerment/personal-data) and the US Green Button initiative (http://www.greenbuttondata.org).
