There is much debate on whether to use renewable energy sources or not and of course, the discussion is veering in the right direction after many years in the balance. But even still we talk about centralising these energy sources such as hydroelectric, solar, wind and water. There is an alternative which today gets little press, and that is the distributed energy system.

If we accept that modern households are energy consumers, which is itself controversial, why pay and maintain robust national and international energy distribution systems, particularly for electricity, when private sources are available, such as roof-mounted solar panels and windmills.

Much work has been done in these areas, particularly in Northern Europe around wooden housing and even energy producing, rather than net consuming housing, using architectural methods such as large bay windows for unidirectional heating, natural materials for roofing and so-called bio positive houses.

These methods need government subsidy now but still fail to get them in sufficient quantities, in part because of the dependency on existing networks and the economics surrounding the current distribution networks in place. Breaking this cycle is a ground-up struggle that can only be advanced by the spread of information on new building methods available.
