同关注。
环保是个好事,不过感觉澳洲政府的补助还不够多(贪心啊),否则家家都该弄个water tank 加 solar panel.
看着澳洲的阳光,不用可真叫浪费啊。
嗯,这次回国发现国内利用太阳能的数量增加了很多,许多人家房子顶上都有太阳能设备。相信澳洲以后也一定会越来越普及。 [/quote]

Savings over time and ease of installation are among factors cited for more builders choosing solar panels over water tanks.
Solar power outshines water tanks
May 26, 2007 The Age
WATER tanks are being installed in as few as 20 per cent of new homes in Melbourne despite the crippling drought.
Under the State Government's five-star rating system new homes must have a tank or a solar panel.
A survey of major builders has found that about 80 per cent of new homes have the solar hot water rather than water tanks.
Builders say that upfront costs, savings over time, ease of installation and the dwindling size of backyards have worked against tanks.
Paul Pitrone, of the state environmental agency Sustainability Victoria, said the survey covered 5000 homes in inner and outer Melbourne.
He said that builders were buying solar panels in bulk, which was helping to lower prices and encouraging rapid improvements in technology.
"The (solar) technology is advancing, the prices are coming down, block sizes are getting smaller and setbacks don't allow for rainwater tanks," Mr Pitrone said.
In some areas with very low rainfall, tanks were not the best option for saving water, he said. Alternatives such as grey water diversion worked better.
Burbank Australia, one of Melbourne's larger builders, now markets its homes with solar hot water as a standard fitting. Home buyers have to pay extra for a tank.
Burbank sustainability manager Fondas Verginis said financial savings were greater from solar — about $200 a year — than tanks — about $50 a year.
But he said that with rising concern over drought, home buyers were increasingly interested in saving water and demand for tanks was rising.
This may force the company to review what it offers as part of a standard house package.
The Sustainability Victoria survey is the first serious attempt at counting the percentage of new homes with water tanks since the State Government introduced its five-star rating system three years ago.
The Building Commission, which oversees the five-star system, has no conclusive figures on the tank/solar split. The commission's regulatory development director, Jeff Norton, said the commission was not convinced about the survey results and would do its own study, based on figures from building surveyors.
The Age revealed this week that energy efficiency expert Dr George Wilkenfeld had recommended an overhaul of current five-star regulations.
Dr Wilkenfeld's report said that new, five-star-rated houses in Victoria were using more energy and producing 6 per cent more greenhouse gas emissions than houses built before the scheme was introduced.
State Climate Change Minister John Thwaites has since confirmed that the Government is set to revamp the five-star rules. |
