Energy self-sufficiency, a dream for a number of homeowners, is now gradually becoming a reality. As isolated projects have already demonstrated, it is perfectly feasible to forgo a conventional grid connection and have a property’s entire energy needs met by renewables alone.

Fuel cells did not seem to play much of a role at the event. Only one of the big manufacturers of heating systems made news in this segment, and what for news: Vaillant is on its way out (more…)
