The Progress of Passive House

The Progress of Passive House

The energy supply market is rapidly shifting from fossil fuel to renewable sources. This transition is necessary, not only to comply with European targets and international and regional protocols on climate change (20% share from renewables on total energy supply by 2020), but it’s also the most responsible way to promote energy security.

The cheapest and cleanest energy choice of all is not to waste it. Progress on this has been striking yet the potential is still vast. Improvements in energy efficiency since the 1970s in 11 IEA member countries that keep the right kind of statistics (America, Australia, Britain, Denmark, Finland, France, Germany, Italy, Japan, the Netherlands and Sweden) saved the equivalent of 1.4 billion tonnes of oil in 2011, worth $743 billion.
