Green Technology by David Flint.

Talking of good news it's worth remembering that green technology is getting better all the time. Two recent examples reminded me of this.

Air-conditioning: The US air conditioning firm Daikin has produced a rooftop unit, named Rebel , that it claims is much more efficient than previous systems. According to the Building Research Establishment in Watford scientists at the US Department of Energy's Pacific Northwest National Laboratory have found that the Rebel "reduces energy costs an average of about 41% compared to units in operation today".

Solar panels: According to Shawn Roe of SRoeCo the efficiencies of commercially available solar panels run from 12 to 17% . Thus, at least 83% of the energy falling onto such panels is not converted into electricity. By contrast a Franco-German team has built an experimental panel with an efficiency of 44.7% - the current world record.

This, of course, is not commercially available, but neither is it the end of the road. Commercial panels can only get better.
