SAY NO TO A NUCLEAR AUSTRALIA
Transportation Has Come a Long Way.
I recently found a story on hybrid sports cars and immediately thought 'Eh?? But aren't hybrids supposed to be somewhat lacking in power? How can this claim of a hybrid sports car be taken seriously?' So I went and had a bit of a look around to see what I could find. And it didn't take long for me to find some very interesting stories on the state of the hybrid industry at the moment. I concentrated on the models that showcase the sports performance side of the vehicle, and surprisingly, I found quite a bit on these flashy cars.Now, I like cars. I like watching motor sports, I like the fact that we've got something that will take us to distant places safely and quickly... and I just like driving a good, responsive vehicle. This is one area of conservation about which I sometimes feel torn. Do you have to compromise on the fun of driving in order to save a few greenhouse gas emissions? Well not any more, it seems.
From what I've seen, there have been some great breakthroughs when it comes to power, fuel economy is at an unbelievable level, and new NiZn batteries promise 30% more power while being cheaper to produce and safer to store. It seems that we don't have a whole heap of excuses left for not considering this option when buying your next car. So let's have a look at a few.
Ok, to start with, the one that took my eye originally, The Fisker Karma.
Ok, so this one is flashy! I could actually see myself driving in this... except it's probably a little expensive for my budget. $80 000 USD will get you one of these luxurious monsters. This one combines a small gasoline engine with lithium battery packs. Apparently, if it's charged properly, it would use only 1 tank of fuel per year. As for the performance, 0-60 mph within 6 seconds and a top speed of 125 mph... I might have expected a little better from a sports car, but hey, that's not too bad. Most of us wouldn't use all of that allowance anyway. But still... this is a car-lover talking...
Then I stumbled across this little beauty, the Tesla Electric Roadster.
Now, this one might be the one for me, I think. Jay Leno even has one! The lines of this vehicle are part Corvette, part Ferrari, part Porsche, and it looks great in black. An electric car that gives you 0 - 60mph in 4 seconds... that's more like it. It can travel up to 250 miles per charge and will set you back a mere $92 000 USD. No worries, I'll have two please, one for daytime use and one for night.
If you're looking for a larger vehicle, something like the Citroen C-Metisse might be the car for you.
How about something a little more affordable? The ZAP Alias is set to be released at a cost of roughly $30 000.
An all-electric three-wheeler vehicle, this one will be able to travel about 150 miles on one charge and go from 0-60 mph in about 7 seconds. For a small vehicle around town, that's not a bad deal... and it wins in the style department too. As yet, it's just another concept car, but with a 2009 release date you can place your order for one now.
Shell Withdraws from the London Array Wind Farm.
While researching an article on wind power today, I was appalled to read of the decision by Shell to sell off their one third interest in the London Array wind farm project. So I had to add this one in here too. A bit of background...On the 18th of December 2006, British government approved the plans to build the world's largest offshore wind farm off the south-east coast of England. This wind farm, London Array, a partnership project between Shell, E.On and Dong Energy, was to incorporate 341 turbines, would cost somewhere in the neighbourhood of £1.5 - 2 billion, and would generate 1000 mW of power, or enough to feed 1% of the UK's energy needs... that's enough to power a quarter of London.
But today's news reports that Shell has decided to sell it's share of the project, leaving E.On and Dong to ponder the future of the project. Shell has defended its' action, saying that ity has decided to sell its stake as part of its "ongoing review of projects and investment choices," and noting that the company has 11 other wind projects across Europe and the U.S.
The Chronicle Herald, on the 2nd of May 2006 reported...
"Friends of the Earth spokesman Nic Rau said Shell’s decision was especially hard to take since it came just two days after Shell posted a 25 per cent rise in first-quarter profit to a record $9.1 billion on the back of soaring crude oil prices."We’re very disappointed that Shell, which touts itself as a progressive green company, is . . . leaving a key clean energy project high and dry," said Rau."
An extract from an article in The Star dated the 3rd of May 2006 states...
"It came just before the consortium signed a contract with a turbine manufacturer - the point at which the companies had to put their money on the table. Shell's move is an economic one, with funds redirected towards potentially more profitable wind schemes in the US.
But the company came under fire from green groups who accused them of leaving the clean energy project "high and dry" while investing in fossil fuel extraction which was wrecking the climate. And on Thursday night the row widened, with opposition parties claiming the UK was in danger of missing green energy targets because of the Government's failure to encourage investment in renewables.
Shadow business secretary Alan Duncan said: "This really is a disaster and it potentially blows a huge hole in Government's already shambolic attempts to hit targets for renewable energy."
I'm sorry, but the numbers just aren't stacking up. Shell recorded a profit of $27.5 billion (£13.9 billion) in 2007. That makes their share of the £2 billion that the London Array would have cost seem like a piddling little trifle, doesn't it? So why have they justified pulling out of this project over a concern about money when they made such a whopping amount last year?
Probably because it's more profitable to sell their oil to the poor ignorant slobs at home. Shell is now making a $75 million (£38 million) per day profit... that's PER DAY... on the price of oil. That means that they could pay for their share of the project after a single day's trading. Uh???
But once the wind farm has been accounted for, how much could they reasonably ask the British public to pay for a resource that's obtained almost free of charge? Not as much as for oil, obviously.
Wind Power is Big Business
Think about it... how many times have you walked down the street, particularly in large cities, lamenting the wind tunnel effect created by the buildings lining the street? It's a pain in the behind, isn't it? Especially if you've just spent good money having your hair styled, or if you have to physically hold down the skirt of your favourite dress out of modesty. Trust me fellas, your wife or girlfriend will know exactly what I'm talking about.But what if we could use that wind tunnel effect in our favour? What if each building could be fitted with wind turbines to catch all of that annoying wind? How much energy would some of our cities be able to produce then? Well, in a little while we'll be able to ask the owners of Bahrain's new World Trade Centre.
This new highrise is an extension to the existing Sheraton Hotel complex and comprises two 50-storey sail-shaped commercial office towers, which taper to a height of 240m and support three 29m diameter horizontal-axis wind turbines. The towers are integrated on top of a three-storey podium which accommodates a new boutique shopping centre, fine dining, business centre and car parking.
The three wind turbines are expected to provide around 10-15% of the power for both towers, representing about 3.5% of the total cost of the project. The blades, each 29 metres in diameter, the first to be integrated into a commercial structure were turned on and tested last month.
An MSNBC report dated the 9th of April 2008, states...
"We truly have pushed the boundaries of environmental architecture with this project," Ole Sangill, a partner in turbine specialists Norwin, said of the project. "It is a testament to Bahrain that private developers are investing in sustainability and pioneering design, which is certainly the future of architecture as it shapes the planet in years to come."Could this be the start of a new trend towards big businesses using wind power to sustain their own energy needs for the future? Why not? This is a viable way to achieve that goal, an opinion that Trammell Crow seems to share with me. This Houston based developer plans to build a newly proposed highrise, Discovery Tower. The 871 000 sq foot project is expected to open in 2010, will cost around $300 million and will sport 10 wind turbines on the roof.
And what about recycling off-shore oil rigs for wind turbines? Wind Energy Systems Technologies are presently engaging in wind monitoring activities on recycled oil platforms off the coast of Texas with an aim to using them to support wind turbines. What a brilliant idea.
It seems that wind energy could become a boon to businesses in the future. Many countries use wind as a significant (and reliable) portion of their electricity power. (Denmark 20%, Germany 7%, Spain/Portugal 20%). In addition, over 4.5 million U.S. homes get their power from wind energy. Texas alone generated 4,446 megawatts of energy in 2007 — enough to power nearly 1.2 million homes. Add Colorado, which generated roughly half of that again, and that's a significant amount of alternative power.
And what about Australia? What are we doing in regards to producing alternative power? Well currently, we're only producing about 1% of our total power usage by means of wind. When you think that the average output of each wind turbine is enough to power around 1000 homes, and then think of all the available vacant land that we have, I think we could do a hell of a lot better, don't you? Have a look at the Australian Greenhouse Office's list of renewable energy generators all over the country. You can click on the map to zoom in and see what's in your area.
So, what about our homes? Could we start by looking up onto our own roofs? But wind generators are huge and ugly structures that we don't really want to look at every morning... aren't they? Well, Engadget had an article about home-sized wind generators, dated 3rd July 2007. It states...
"Generally speaking, wind generators have been reserved for more macro-scale operations, but a West Australian inventor "believes he has developed a way to generate electricity for homes using wind power." This residential approach utilizes a modular turbine that is minuscule enough to perch atop nearly any roof without causing too much unsightliness, and can create power for the house to consume as the wind pushes its blades."Well, that makes one think, doesn't it?
Solar Thermal Energy
Solar Thermal towers collect the heat from the sun in a completely different way than by using photovoltaics (solar panels). A solar panel converts the sun directly into electricity, whereas this method concentrates the sun's rays onto an area that collects the heat. That heat boils a liquid (such as water) and produces steam, which is then converted into electricity. This may seem like an added step in the process, but in actuality it is more efficient in large-scale production. Heat can be stored more easily than the electricity produced by panels, hence solar thermal towers can provide a more even energy source for a longer time.Higher operating temperatures allow for different technologies to be used. One proposed method utilizes liquid fluoride salts, using multi-stage turbine systems that allows the plant to use higher-temperature dry heat exchangers for its thermal exhaust. This reduces the plant's water use, which comes in handy if it's situated in the desert... where large solar plants are the most practical. With the use of a back-up system for the rare emergencies, this method of obtaining power becomes very attainable.
This is a very promising way to produce power to the masses, in my view. Have a look at Wikipedia's list of Solar Thermal Power Stations from around the world.
Now, there are several different designs when it comes to solar thermal power stations. Most people have, at one stage or another, seen or heard about the solar farms that use masses of mirrors surrounding a central tower structure. These Power Tower designs use mirrors (called heliostats) to focus the sun's rays on a collector at the top of the tower. But to do this each mirror needs to be fitted with a motor to track the path of the sun, maximising the heat collected. This increases the cost, and decreases the attraction of this type of solar tower.
Parabolic trough power plants use a system of curved troughs, which reflect the sun's rays onto a receiver positioned above the trough. As the position of the sun changes, the whole trough tilts so that the focus remains on the receiver. However, if the troughs are positioned parallel to the sun, it does not require adjustment of the mirrors, as the light is simply concentrated on another part of the receiver. So in this way, the trough design takes out the added cost of a tracking system.
Another design uses a large, reflective, parabolic dish (similar in shape to a satellite dish). It focuses all the sunlight up onto to a single point above the dish, where a receiver captures the heat. Typically the dish is coupled with a Stirling engine in a Dish-Stirling System. These engines require no fuel, creating a rotational kinetic energy that can be converted to electricity using an electric generator. Of all these technologies the solar dish/stirling engine has the highest energy efficiency. A single solar dish installed at Sandia National Laboratories National Solar Thermal Test Facility produces as much as 25 kW of electricity, with a conversion efficiency of 30%, compared to around the 20% of the parabolic systems.A linear Fresnel reflector power plant uses a series of long, narrow mirrors to focus light onto one or more linear receivers above the mirrors, much like the parabolic system. The receiver is stationary and so fluid couplings are not required (as in troughs and dishes). The mirrors also do not need to support the receiver, so they are much simpler structurally. When suitable aiming strategies are used this can allow a denser packing of mirrors, thus producing more and/or saving valuable land space when needed. Another advantage of this design is that lenses are cheaper than mirrors. Furthermore, if a material is chosen that has some flexibility, a less rigid frame is required to deal with wind instability. It does bear mentioning however, that no full-scale thermal systems using Fresnel lenses are known to be in operation, although products incorporating Fresnel lenses in conjunction with photovoltaic cells are already available.

Can We Rely on Renewable Energy?
"But can we really rely on renewable energy? What happens when the sun stops shining or the wind stops blowing?"This is a question that was asked of me some time ago. I had all intentions of answering at the time, but couldn't because of our absence from the net. So, expanding on the groundwork I initially put in, here is my response.
Well, there are many different renewable energy sources. Some, like wind power and rooftop solar panels, are intermittent at a local level. But when they are spread over a sufficiently large area, with different climatic conditions, they are barely more intermittent than coal. It is unlikely that there will be no sun or wind anywhere across the electricity network of Australia. By deploying wind and solar across the landscape we can reduce any intermittency of wind and solar generators. And using these technologies in the home has the added advantage of producing electricity where it is used, so less energy is lost in transmission. On the subject of lost energy, did you know that about 11 per cent of the electricity produced at a big coal-fired power station is lost while being transported to the end user? So it seems that the problem of transporting power is something that all deliverers of power have to combat.
So yes, both wind and solar power are subject to the weather. However, weather forecasting is very reliable and, in most cases, any lack of sun or wind can be predicted and compensated for (for instance, by cranking up hydro and biomass generation). But in contrast, coal-fired generation suffers unpredictable outages and breakdowns that can and do plunge the electricity grid into crisis.
Solar power is particularly useful for delivering power at times of peak demand. Hot, sunny days when people are using their air conditioner, will generally be days when there is plenty of solar energy generated. And consider this... Solar water heating is hugely underused in sunburnt Australia. Less than five per cent of houses have a solar water heater. Some other countries, Israel, Spain and Ireland, are making solar water heating mandatory, while China has over 60 per cent of the world's installed solar water heating capacity.
Now, some technologies, like hydro power are highly predictable and controllable. They can be deployed when it is most useful, providing either baseload or peak power. Eraring Energy has a number of hydro-electric plants and the Stanwell corporation is also using power derived by means of hydro generation. As for Tasmania... well, we've all heard about the successful use of hydro power in the Derwent River catchment.
Bioenergy is another source of power that is being currently utilised in Australia. Woodlawn, near Sydney is Australia's largest bioreactor landfill. Veolia Environmental Services produces power generated by the methane that our waste produces. They also have plans in the works to incorporate a large scale windfarm on the Woodlawn site.
Emerging technologies, like geothermal could theoretically provide large quantities of baseload power in Australia long before a single nuclear reactor can be built (they take 10-15 years) or a commercially feasible carbon capture and storage coal-fired power station could be developed. Geodynamics is a Brisbane-based company currently researching hot-rock technologies in the Cooper Basin.
Solar thermal is another promising technology being researched by the Stanwell Corporation, one which I want to expand on soon. You can download a PDF file by the Environmental Protection Agency outlining the Stanwell Solar Concentrator here.
So why is it that people still think that renewable energy sources are not viable when all these technologies are available? It seems to be hard for many to accept, but solar and wind are not the only alternative sources available to us. With a combination of several or all of these methods we are completely able to supply power in a safe and renewable way. We just have to get over the idea that it has to be either one technology or another.
Cloncurry to get a Solar Thermal Tower
The western Queensland town of Cloncurry is expected to run entirely on solar thermal power by the year 2010. The Queensland government is set to spend $7 million dollars on the project, a solar thermal tower which will store heat by using 8000 mirrors to concentrate the sun's rays onto graphite blocks. Water is then pumped through these blocks, generating steam which turns turbines and generates electricity. As graphite is such a good conductor of heat, the tower will be able to successfully generate electricity well into the night. The station is set to deliver about 30 million kilowatt hours of electricity a year, enough to power the entire town continuously 24 hours a day.Premier Anna Bligh states, "We're going to build a 10-megawatt solar thermal power station. It's a real breakthrough for electricity generation. The technology we’re going to use in Cloncurry, will ensure the power station keeps generating electricity even when the sun is not shining. The town of Cloncurry has long claimed the title of having recorded Australia's hottest day -- 53 degrees (Celsius) in the shade in 1889, so I reckon we're on a winner. "
Minister for Sustainability, Climate Change and Innovation, Andrew McNamara said of the project, "While the introduction of alternate energy sources and the reduction of emissions comes at a price, the refusal to do so comes at a potentially much higher cost."
Mines and Energy Minister Geoff Wilson agrees, adding, “This project’s a winner on several fronts. It will cut greenhouse gas emissions with clean energy powered by the sun and it will save money in the long term with less money being spent on upgrades to the local network.”
Find the full Ministerial Media Statement here.
$7 million dollars to power a whole town with a population of over 3000 people? Considering that Australia is still one of the worst greenhouse gas emitters in the world, it's a drop in the ocean, I would say... and a step in the right direction. Now we need to start leaping.
Coal Seam Methane Extraction
For many years now, miners have known that coal seams produce methane gas. It used to be that this gas was merely a hazard to be released before the miners could even think about taking any of the 'valuable' coal from the ground. Now though, we have realised that the release of that gas is a massive waste of what is another valuable resource.Methane is a flammable gas that when released into the atmosphere contributes to global warming. It is also a very good energy producer when burnt, producing less carbon dioxide than other hydrocarbon fuels. Methane gas (often called bio gas or natural gas) has many current uses, including being used for heating, cooking and as a vehicle fuel.
Methane production comes in many forms. It can be extracted from the rotting of organic matter including livestock manure, wastewater sludge, human refuse in landfills, or any other biodegradable feedstock (vegetation). Even the ocean and wetlands produce methane.
But the major source of methane is to extract it from the ground, where it is produced in large volumes by the coal under our feet. This method is known as Coal Seam (or Coal Bed) Extraction. The methane which is in the coal is released when the coal seam is depressurised. To do this, the water within the seam is pumped from the ground, causing a drop in pressure. This forces the methane to desorb from the coal, and this is when it is captured, compressed and piped to market.
There are a number of Australian coal mines that have been using this method for some time now, including Santos, which has been utilising methane gas extracted from several mines in the Bowen Basin in Qld. Moura Mine, located in the Bowen Basin in Queensland, established a commercial coal mine methane business next to its coal mining operations in 1996. And in New South Wales, the Appin and Tower Collieries, operated by BHP Billiton, produce electric power by using drained coal mine methane. The Australian Coal Association has some more information here.
The Australian government has had projects in the pipeline since early 2003, and continues to fund projects today.

Controversy as FutureGen Plans are Cancelled.
Plans for FutureGen, a near zero emission coal fired power plant planned for Mattoon Township, Coles County, Illinois was cancelled by the Department of Energy (U.S.A) on Janurary 29 2008, among much controversy. The DOE announced that it would pull its funding for the project, after concerns of costs rising to higher than expected levels. However, some Illinois local and state officials have experessed frustration over the time and resources wasted by the state in competing for the FutureGen contract, and have questioned why the decision was made after the Illionois site was chosen over one in Texas.Mattoon mayor David Cline said "one could question the motivation of the Department of Energy which was ready to move forward with the project until a site other than Texas was chosen." Illinois senator Dick Durban claimed that "when the city of Mattoon, Illinois, was chosen over possible locations in Texas, the secretary of energy set out to kill FutureGen."
Samuel W Bodman, U.S. Energy Secretary however, has countered these claims, explaining that that the restructuring of the FutureGen project will "equip multiple new clean-coal power plants with advanced CCS technology, instead of one demonstration plant. That will provide more electricity from multiple clean-coal plants, sequestering at least twice as much CO2 and providing for wider use and more rapid commercialization."
The move is likely to delay the project as other members seek the additional funds that the DOE was to provide. Despite the cancellation of funding by the DOE, the FutureGen Alliance continues to move forward with the project, opening an office in Mattoon and planning to buy the land for the plant in August 2008, in partnership with a local group.
According to the New York Times in an article dated January 31, 2008...
"The Energy Department on Wednesday canceled its main program for demonstrating how to use coal without adding to global warming, saying the project needed an overhaul to rein in soaring costs. The announcement ends a program started four years ago and described at the time as “one of the boldest steps our nation has taken toward a pollution-free energy future.” The program, called FutureGen, was also intended to provide hydrogen for fuel-cell cars and other uses. But the estimated cost has risen to about $1.8 billion from $1 billion, and officials feared it would increase. The department said it would start over with a new program, but that is unlikely to happen before the Bush administration leaves office."
According to an article on CNet News.com, February 1, 2008...
" The FutureGen Alliance, which includes companies like Foundation Coal and Peabody Energy, says that the DOE initially agreed to contribute $800 million to the project. The DOE's share has only risen to $1.1 billion. Alliance members have also agreed to provide the DOE partial or full repayment for overruns. "The cost is manageable," the organization read. The DOE also claimed that financing such a project was inappropriate. Hardly, said the Alliance. Power plants are always financed. It also disputed the DOE's claim that the plant wouldn't be commercially viable. Not so, says the Alliance. Finally, the DOE claimed that the new projects will sequester as much carbon dioxide at a lower cost than FutureGen. "The Mattoon site as currently configured can sequester approximately 2 million tons per year," the Alliance said. The new projects aim for 1 million tons a year--or half as much. Whoever is right, the dispute seems to add to the Department of Energy's (or at least the Department as it has been configured for the last couple of years) inability to keep its mind on research. In the '90s, it kicked off an ambitious program to build hybrid cars. Japanese manufacturers weren't invited. In response, Toyota and Honda released hybrids. The DOE program was canceled. It then shifted to developing a hydrogen economy. We're still waiting on that one."
A report from the Washington Post, dated February 16, 2008 states...
"President Bush announced in 2004 and then continually promoted a public-private venture he hoped would usher in an era of clean coal and be a cornerstone of U.S. efforts to address global warming. The FutureGen plant would have created electricity by stripping coal of harmful carbon dioxide and pumping the gas underground. The result would be power generation with zero greenhouse gas emissions. In December, Matoon Ill., was selected as the site for the coal plant. And then, on Jan. 30, Energy secretary, Samuel W Bodman pulled the plug."
Personally, I believe that one should wonder about the motives for such a move. Texas is the home state of President Bush, after all. But even if it is all about money, shouldn't the $50 million US that the state of Illinois has already sunk into the project bear some consideration. $40 million of this came from US taxpayers, and is now just wasted funds. Why scrap the project for someone else to take up when such a large amount has already been invested, especially when the government was so much in favour of the project initially? It doesn't really make sense.
Sustainable Houses.
Well, hello there folks. Long time no see, eh? I haven't been here for quite some time now, due to an enforced vacation from the net. I'm back now though, at least for a few months, and I've decided to take up the good fight once again.I read a good report of sustainable houses from Radio National and wanted to provide some links for your perusal. These houses show that good things have been done in respect to the research and implementation of alternative energies. These are excellent examples of some of the things that can be done today to aid power production in your own home, and even in highrise offices. Please read these informative articles.
Chippendale Terrace House...
"A walk through a 100 year old terrace in the polluted inner city suburb of Chippendale. The house has been renovated and fitted to become self sufficient. Two adults and two children live there. It uses solar power which is connected to the grid so the house has no electricity bills, and actually feeds some power back into the grid. All their waste water and sewage is treated on site. The re-cycled water is used to flush the toilet and water the garden. They have a gutter filter which cleans and collects rainwater for drinking."
Sustainable House in Central Australia...
"Self-sufficiency in an arid climate. The first of several houses to for the Arrillhjere Corporation on aboriginal land, 30 killometres west of Alice Springs. It's a mud brick house, designed to be energy efficient and suitable an Aboriginal lifestyle in central Australia. The owner, Olive Veverbrants is keen to promote an environmental consciousness amongst her people. She is not yet on the phone, but is offering working holidays in return for expertise."
Melbourne Water Autonomous House...
"An ordinary house in suburban Melbourne that's far from ordinary . It's self sufficient in water. The residents are not connected to the water main and they don't pay water rates. Toby Murcott walks around the house with owner Marie Q. The water source is local rainfall, collected on the roof and stored in a large tank under the house. The house has water efficient appliances, and the grey water from the kitchen and laundry is recycled onto the garden. All the stringent health standards required by local council, such as e. coli levels, have been met. Some council representatives were supportive, some were not. Marie Q & James Stronelle believe there's an urgent need to reduce water consumption in Australia. They're keen to spread the word on how to achieve a system like theirs in an urban situation."
Nimbin Permaculture House...
"Lynne Malcolm visits a mud brick house situated on the Jarlanbah Estate, a rural residential subdivision, a few kilometres from Nimbin in sub-tropical Northern NSW. The house has a passive solar design, the walls are mud render applied over old corrugated iron and the centre of the house, which is mud brick gives the thermal mass. All the wood in the house is oiled with natural oils rather varnish or lacquer. There are Japanese style influences in the house's interior as Nigel lived in Japan for 12 years and his wife Yoko is Japanese. People are welcome to stay for bed and breakfast at Nigel and Yoko's house."
And just to prove that an entire community can survive on alternative energy sources, check out what the people of Southwell, in Nottinghamshire England have done. All of this in an almost sunless climate. Imagine what we could do in Australia.
English Eco-Village...
"An energy efficient village that would make Robin Hood proud. Brenda and Robert Vale designed and built their first autonomous house in the village of Southwell, in Nottinghamshire. The house was in an historic area and its appearance had to meet strict heritage guidelines. Despite this the house collects its own water and is energy and water autonomous. Techniques inclued very thick walls and the house is very well insulated - the roof insulation is half a metre thick shredded newspaper. The windows are triple glazed with special low emmission coating. Following the success of these houses the Vales were asked to write building specifications for autonomous houses, houses with low CO2 emmissions and houses without any space heating. The local council wants to build a 'zero CO2 village' village based near Sherwood Forest in Nottinghamshire. The village was formerly a pit village. Now with the coal mines closed and local unemployment high, it's hoped demonstration Sherwood Energy Village will take the town forward."
And just a quick one from the Aussie front, Council House 2 in Melbourne. Have a look at the government page dedicated to this highrise wonder and please, check out some of the links and have a really good look around the site.
Council House II...
"The City of Melbourne's six star green building CH2 opened in August 2006. An independent report evaluating the indoor environment quality and occupant productivity for the first year of full operations has now been released. The CSIRO report includes analysis from independent consultant Adrian Leaman of Building Use Studies in the UK, and indicates that productivity has improved by an impressive 10.9 per cent."
