This day has not been chosen by chance for the presentation of the report on the power outage of last November: Brussels is actually hosting the first "Week of sustainable energy", which covers over 40 events and brings together experts, organisations and bodies from all over the EU. "A number of conferences and talks will explore explains a release from the Executive the subject of sustainable energy and its potentials for all of us". Happenings will be hosted all over the city, as well as in France (Grenoble) and Spain (Murcia), "to highlight the pan-European character of the event". This special week "might become as the Commission would like it to a fixed yearly appointment to discuss sustainable energy in Europe". The workshops will address different topics, for instance how to "recycle cooking oils as fuel or solar panels as building materials", or whether to "go for low-consumption electric appliances". Andris Piebalgs, EU energy commissioner, sees this Week as one of the tools to accomplish "a veritable revolution" in this sphere, since "the energy policy does not just affect the legal sphere, but is also a matter of communication, listening, collaboration among all the people concerned".
