I was in Bunnings yesterday looking for an exotic light globe and saw a couple loading up with "cheap " 100 watt globes at 45 cent each . I asked why they didnt get the 23 watt compact fluro globe and was told it was too dear . Told them 45 cents plus 100 kwh @ 16 cents came to $16.50 versus $5.00 globe and 23 Kwhs @ 16 came to $8.70 so they would be $8.00 better off and probably breakeven in 3 months when they had to pay their power bill . Their answer was to take one new globe as well as all the 45 cent bargains . Surely if the government is serious about green house gas and moderating electricity demand it should be mandatory for globe retailers to display the life cost of their products similar to the tabaco danger ads . Also begs the question of how responsible is it of the "Bunnings of the retail world " to still be selling incadescent globes . They had an absolutely massive display of down lights (all 50 watts plus massive heat givers ) when there are now slowly coming onto the market LED down lights that are about 3 watt .
I have had my 90 evacuated tubes hot water preheater now for 6 months and so far have probably peaked at saving about 60 kwh on the best day but it looks like a return of 30 to 40 percent on my capital investment of $8000 (no gov grant available though when finished eligible for selling RECs )and about to install a feed back solar electricity system which will return between 3 and 5 % on its capital which when compared with the new reserve bank rate or the massive negative returns on the share market is looking like a reasonable investment as well as cutting our bought electricity Last year we used about $9000 electricity and hope the reduce this greatly over time but there is a limit what we can cut.
