Recently there’s been good news that the Boloco Rock wind farm project in the Monaro region is still in the pipeline. Here’s some information about a wind farm that’s been successfully operating in Australia since 2001. The Albany wind farm is 12 km south-west of Albany in Western Australia, at an elevation of 80 metres above sea level, right on the coast. The height, proximity to the coast and the transmission infrastructure give this wind farm an exceptional location. The Albany wind farm has twelve 1800kW wind turbines, 65 metres high with blades 35 metres long. At the time of installation the turbines were some of the largest available in the world, and were the largest ever installed in the Southern Hemisphere. They operate automatically, and maximise power output from the wind speed and direction. The blades of the Albany turbines spin slowly, at a top speed of 22 revolutions per minute in the strongest winds, equalling one revolution about every three seconds. In the year 2001 the wind farm supplied the equivalent of 75% of the electricity requirements of the city of Albany, that is, about 15,000 houses. Occasionally the wind farm exports energy through the power grid. The Albany wind farm lowers greenhouse gas emissions by about 77,000 tonnes per year. In 2008 the plans were released to expand the wind farm by adding six new turbines. Technological developments in the years since 2001 mean that the six new turbines, though the same size as the older ones, will provide 30% more power, and enable the farm to supply up to ninety percent of Albany’s electricity requirements.

Buildings use a lot of energy. Many buildings are constructed and used in such a way that the energy required to keep them going is immense.
The City of <st1:City><st1:place>Melbourne</st1:place></st1:City> has published a guide called Greening Your Building with useful information for sustainable initiatives related to design, maintenance and management. These initiatives not only save energy but also give suggestions for reducing running costs for buildings. Suitable for applying to general day-to-day running, retrofitting, replacement of equipment, for ideas for incorporating green practises or for use at the design stage.
Topics covered in the 85-page booklet include managing hot water demand and electrical demand, cleaning practises, heat loss and gain, landscaping, ventilation and air conditioning, lighting efficiency, purchase and management of office equipment, renewable energy, rubbish and recycling, transport and water conservation.
It is easy living in the country to think that we don’t need to worry about such matters as building design, because we don’t use those energy-inefficient glass-walled high rise offices in our towns. But these measures can be applied in varying degrees to any size business. Each section of the booklet gives benefits, risks, opportunities, costs, and future benefits. For example, domestic hot water use: a suggestions include reducing temperature of water supplied, or not supplying hot water to hand basins in toilet facilities. This luxury is not necessary under most circumstances, and the benefits in terms of energy and equipment costs are immense. Domestic hot water uses approximately 5% of overall energy consumption in workplace buildings and 16% of gas consumption.
The guide is available to download for free (only 870 kb) from https://www.melbourne.vic.gov.au/info.cfm?top=218&pg=3933 .
On Tuesday March 10th, Victorian Premier John Brumby announced that his government will provide up to $100 million in a dollar-for-dollar deal with the Federal Government, to develop a large-scale solar power station in Victoria. The power station project for which the Victorian government is seeking expressions of interest will produce about 330 gigawatts of electricity per year: enough to power fifty thousand homes, or all Victorian Government departments including schools, police stations, roads and even the Melbourne Zoo (a place well worth visiting if you are ever in Melbourne, by the way).
The project is to be complemented by a bill introduced into Victorian Parliament on the 10th March which will support Victorian households in investing in solar photovoltaic cell systems. The bill is related to a feed-in tariff scheme which will offset the cost to householders of installing solar electric technology. A credit of 60 cents per kilowatt will be paid for energy fed back into the system. This tariff system will be in effect for fifteen years and allow up to one hundred thousand households to participate.
This double edged approach to solar energy is intended to help all Victorians to reduce their carbon footprint: by both assisting people to install their own solar power and by encouraging investment in large scale solar for the benefit of all citizens.
It is encouraging to see state governments acting so definitely to develop renewable energy sources. Watch this space for more.

Most Australians own a mobile phone and replace it every two years. That’s a lot of old mobile phones lying around in people’s drawers. As a pretty unmotivated mobile phone owner who uses mine for keeping track of family members during complicated outings, playing “Snake” in boring moments on my old phone and taking photos on my new one (very exciting; all I have to do now is work out how to get them onto the computer), I am already onto my second phone. And yes, the old one is lying around in my room. But why not just leave it there, or throw it into the bin? Mobile phones contain valuable metals such as gold, nickel and cadmium. Ninety percent of these metals can be recovered. Plastics from phones can also be recovered and reused. One tonne of circuit boards can yield almost the same amount of precious metals as 110 tonnes of gold ore, 123 tonnes of silver bearing ore and 11 tonnes of copper sulphide ore. These are non renewable metals whose extraction from the earth is hugely expensive in terms of energy, cost to the environment, and labour. MobileMuster is the official national recycling program of the mobile phone industry in Australia; this year’s aim is to collect 130 tonnes of discarded mobiles. MobileMuster phone collection points can be found in Cooma at Cooma-Monaro Shire Council’s offices, the Cooma Landfill and at Cooma TAFE College. There is a collection point at Snowy River Shire Council’s office in Berridale, as well as at two locations in Jindabyne. All you need to do is delete personal information from your disused phone and take it to one of these points. For more information pick up a brochure at your shire council, or go to: www.mobilemuster.com.au
End of January. Hot. Hot. Hot. Too darn hot. I’m not challenging any climate change sceptics to an argument, but when I first moved to Cooma in late 1984, any evening outing in summer required taking a jacket. Lately perhaps, a jacket soaked in iced water would be the thing to take. The news is full of power cuts due to overloading of the electricity system. It seems odd to me that more power goes in to cooling than it does to heating… but then, you know how long I’ve lived in Cooma now… anyway. It is logical that when the temperature is over thirty, people want, or in the case of the old and infirm, need, to be in a cooled environment. What bothers me is when, going about one’s business, one enters a shop or office and after a while finds that the clothes that were appropriate-to-too-warm for outside are completely inadequate. It’s nice to be cool. It’s pretty stupid to have to put on a jumper to stay indoors in summer. I read not long ago that the excessiveness of air-conditioning in modern times can be attributed to the wearing of business suits by men. They have to look spiffy. The suit is the only way. The suit is completely unsuitable for our climate in summer. Instead of changing the way they dress, they use air conditioning to a frigid degree. Whole cities are built on this. I urge everyone to do several things before they set an air conditioner more than a few degrees below the ambient temperature: 1. Dress appropriately for the weather; 2. Open your windows and doors when it’s warmer outside than in, and close them when it’s hotter (trust me, Dr Karl agrees with me on this one); 3. Close the curtains (rubber backed keep out more heat). And don’t pour cold air from your shop out through the open door, nice as it is for passers-by. Then we might avoid power cuts.
