Most commercial buildings in Australia have moved away from incandescent bulbs to compact fluorescents, which are much more energy efficient and last longer. The limitations of CFLs are slow warm up time, early failure if frequently switched, and high cost for dimmable CFLs. Additionally some speciality bulbs, such as chandelier bulbs, don’t have readily available CFL equivalents. But as CFLs are four or five times more efficient than incandescent in our energy audits we always try to build a strong case for switching to CFLs.
But incandescent may be getting a second life. Australia enacted the first legislation banning sales of low efficiency lamps (incandescent) and the US followed. With a much larger market than ours this has sparked some innovation in the design of incandescent lamps.

When your IT equipment is due for upgrade it’s the perfect time to greatly reduce your computing energy use. But how do you know what products to use?
The US EPA Energy Star standard is now the defacto standard for energy use computing equipment. This certifies products as either being energy star compliant or not.

Its now possible to buy a 200 watt micro wind turbine for $449 from Jaycar electronics. A couple of years ago they were even including a four meter tower with the wind turbine. If you live in a windy flat spot with no trees or houses upstream of the prevailing wind it’s a bargain. But don’t waste your money buying one of these and putting it on top of your suburban house, in your backyard or on top of your office building.
Encraft in the UK have published the results of a trial on the operation of 26 building mounted wind turbines with a combined 168,950 hours of operation. The purpose of the trial was to see how grid connected small wind turbines performed on a range of building types and locations. It was undertaken in 2007 and 2008. A range of turbines from different manufacturers were tested, with capacities from 400 to 1,250 watts. The report includes photos of each installed turbine. Looking at the photos it becomes pretty obvious that the wind turbines that performed the best were mounted high, well above surrounding buildings.
