How Green Dialysis Could Save Tens of Thousands of Lives per year

November 11, 2010 by Tom Raftery

Understanding how processes and systems act on one another is key to sustainable living. Sustainability means living without externalities – because everything we do, as individuals, organisations or companies has a cost and an environmental impact. There is a clear parallel with healthcare- which requires a deep understanding of how processes and systems act on one another. Now a research project at Geelong hospital in Victoria, Australia aims to extend healthcare models directly into the environment, and vice-versa.

Associate Professor John Agar, the Director of Renal Services at Barwon Health, said:

?Dialysis is the most water and power-hungry of any individual medical therapy.?

Each dialysis patient treatment uses more than 400 litres of water and 6 kWh of electricity. But Geelong is now using water recycling and solar power to afford the same level of care with a far lower environmental impact. Indeed the dialysis department further reduces its cost by selling excess power from its solar panels to the electricity grid. Healthcare meets smart grids. Makes sense. The idea of demand response in dialysis might strike you as somehow unethical, but what could be more ethical than effectively lowering the costs of healthcare to the broadest range of patients? Of course solar power doens’t make sense in all geographies, but it certainly does in many regions of the world. And there might be alternative, on the Eastern Sea-board, or the UK- namely wind or tidal.

Hat tip to Fresenius Healthcare, the German renal treatment company behind the initiative. Seems the German government feedin tariffs for solar power are showing real benefits in unexpected areas. Subsidise solar to subsidise healthcare… I said there were no externalities in sustainability, didn’t I?

However – its certainly not all good news for Fresenius. As a major provider of renal care in the US the company has to be horrified by the appalling record of dialysis related deaths. According to a new ProPublica story in the Atlantic.

?Every year, more than 100,000 Americans start dialysis. One in four of them will die within 12 months?a fatality rate that is one of the worst in the industrialized world.

The article is pretty horrific. The problem, sadly, is poor sanitation and an assembly line mentality to healthcare driven by the need to cut costs. Clearly we have a long long way to go before dialysis can be considered properly sustainable… and offer safer outcomes and decent quality of life to patients. Step one to improving margins and so reducing the cost-cutting mentality in dialysis care may well be reducing the costs of water and power.

It really is all connected.

No, energy is not too cheap!

November 4, 2010 by Tom Raftery

Is energy too cheap to motivate consumers to change their habits and use less?

In the Smart Grid Technology conference I attended in London last week a number of discussion points came up over and over again. I wrote already about how utility companies are wondering how to engage their customers around smart grid projects. Another topic which raised its head frequently was the question of how to motivate customers to change when energy is so cheap!

The obvious answer is to raise the price of energy, and this will happen over time, but it is the wrong answer – in the short-term at any rate.

The issue is not that energy is too cheap, rather it is that people have lots of demands on their attention. To make it worth people’s time to become involved in energy saving activities, if the return is not very high (because energy is cheap) then the process of reducing energy consumption needs to be made simple!

Look at the thermostat above. This is the thermostat to control the central heating/air conditioning in my home. I like to think I am reasonably technical. I have been a Windows sysadmin for a multi-national company, managing Windows, Exchange, Active Directory, ISA and SQL Servers. I edit php files regularly, I remotely manage my own CentOS server via SSH and I’ve even done quite a bit of regex scripting of .htaccess files!

But this thermostat is beyond me!

I know it has a timer, so it should be possible to set it to come on and off at pre-arranged times. Should. Getting it to do so seems to require a Stephen Hawking-like intellect. And, even if I did manage to figure it out, it is so unintuitive that the next time the clock goes forward (or back), I’d have forgotten again and would need to start over! Which begs the question, if my phone knows when to change its clock forward or back, why doesn’t the thermostat – but I digress!

This is far too much hassle entirely. So I don’t use the timer in my thermostat. Or any of its functionality (apart from on/off). And I’m far from being alone in this.

Home energy management systems have, to-date, suffered from having appalling user interfaces. Consequently, no-one uses them. Why would they? They are hard to use and energy is cheap. The room is too hot? Rather than trying to figure out how to turn it down, just open the window!

However, if energy management were made simple and no effort were required to make changes, then it wouldn’t matter nearly as much that the savings were not substantial.

Making energy device interfaces easier to use is no silver bullet mind. This kind of approach needs to be combined with a culture of increased client communications, as I outlined in my earlier post. However, combining these two strategies would go a long way towards making people energy responsive.

And here are this week’s Green Numbers:

Timberland Commits Five Million Trees in Five Years to Help Solve Critical Issues in High-Risk Environments

“The Timberland Company (NYSE: TBL) believes it can help alleviate hunger, create jobs, protect wildlife and preserve the environment…all through the simple act of planting a tree. Make that five million trees – in five years.

It’s a bold pledge in support of a bold vision. And although the notion is pretty simple – plant some trees, do some good in the world – Timberland’s global reforestation program recognizes that success doesn’t come quite as easily as that.

“You can’t just throw a sapling in the ground and expect the world to change,” said Timberland President & CEO Jeff Swartz. “But done thoughtfully and strategically, with committed partners, planting trees really can lead to meaningful long-term solutions to a whole host of environmental, social and economic problems.” “
Spending cuts ‘to cost 60,000 green jobs’

Plans to build three new factories to make thousands of giant offshore wind turbines that would create an estimated 60,000 jobs are set to become the latest casualty of the spending review, it has emerged.
The previous government had pledged ?60m to upgrade ports, mainly in the north-east, to enable them to handle the next generation of giant turbines for installation off the UK coast.

Siemens and General Electric have announced plans to invest ?180m in two new manufacturing facilities in the UK, but say this is conditional on the necessary work on nearby ports. Mitsubishi is also interested in building a third factory.

But the Guardian has learned that the competition inviting ports to bid for the funds is likely to be scrapped
Microsoft 2010 Citizenship Report – Microsoft Corporate Citizenship Report 2010: Social Responsibility

Still quite lightweight, Microsoft have finally, with their 2010 corporate citizenship report, produced a report following the GRI reporting guidelines.

Hopefully this is the beginning of proper CR reporting from Microsoft.
GreenBytes Nabs $3.5 Million More For Energy-Efficient, Enterprise Data Storage

According to a new SEC filing, Rhode Island startup GreenBytes Inc. added $3.5 million to the series A round they raised last year, led by Battery Ventures and initially consisted of $7.5 million.

GreenBytes provides ?energy-efficient, inline deduplication storage appliances.? In plainer English, the company makes hardware and software that IT operations teams use to store and protect huge amounts of data, and to control how much energy they must use to do so. GreenBytes claims its technology can cut storage power consumption by 50%.
Students Find $350 Million in Savings at Bloomberg, eBay, McDonald?s | Fast Company

Major corporations can save millions of dollars with simple energy efficiency tweaks–if they know where to look. That’s where the Environmental Defense Fund’s Climate Corps program can help. The three year-old program plays host to 51 MBA students that are sent to 47 corporations to dig up energy savings.

This year’s group found $350 million in net operational cost savings at companies including Bloomberg, eBay, McDonald?s, Pepsi, Target, Verizon, and Xerox. So how did they do it?
Eurostar unveils ?700m investment in new generation of energy-saving high-speed trains

Eurostar has today announced a planned ?700m investment in its rolling stock that will result in the rail operator running some of the greenest trains on the planet from 2014.

The company revealed it is to buy 10 new trains and refurbish its existing 28-strong fleet as it looks to further build on its position as a low-carbon alternative to short haul flights.

Engineering giant Siemens is set to be awarded the contract to manufacture the new electric e3202 trains, which it estimates will consume about 10 per cent less energy than existing models.

The e3202 is an updated version of Siemens’ Velaro, the fastest high-speed train in the world, which over a distance of 100km consumes 0.33 litres of petrol equivalent per seat ? about the same as a can of cola ? and produces at least three times less CO2 per person-kilometre than a standard passenger flight.
Top 3,000 Public Companies Responsible For $2.15 Trillion Worth Of Environmental Damage In 2008 – UN Report

Global environmental damage caused by human activity in 2008 represented a monetary value of $6.6 trillion, equivalent to 11% of global GDP, calculates a study released today by the UN-backed Principles for Responsible Investment (PRI) and UNEP Finance Initiative.

Those global costs are 20% larger than the $5.4 trillion decline in the value of pension funds in developed countries caused by the global financial crisis in 2007/8.
IBM wins $100 million EnergyAustralia Smart Grid deal

IBM has been named systems integration partner for the $100 million smart grid initiative led by the EnergyAustralia consortium. IBM will lead the development of Australia?s first smart grid network, following the formal contract signing of the deal between EnergyAustralia and the Australian Government and work will commence immediately.
Smart meters will reach 302.5 million units in 2015

The worldwide installed base of smart electricity meters will grow at a compound annual growth rate of 31.1 percent between 2009 and 2015 to reach 302.5 million at the end of the period.

Symantec need to stop hiding their Green light under a bushel

October 6, 2010 by Tom Raftery

I attended Symantec’s Vision 2010 event in Barcelona yesterday and I found it to be hugely frustrating!

Symantec are one of the world’s largest computer security companies with 31,000 customers, 18,400 employees (PDF), and revenue in 2009 of $6.2 billion.

At yesterday’s Vision event however, they missed lots of great opportunities to talk up their Green story! I sat through the keynote from CEO Enrique Salem and presentations from the business unit leads and there was not one mention of the word Sustainability or even Green.

Deepak Mohan at Symantec Vision 2010

Deepak Mohan, SVP of the Information Management Group came closest when he mentioned efficiencies associated with de-duplication, eliminating redundancy, reducing data transfer and more efficient (that word again) search. Guys, these are obvious Green wins!

Things improved considerably in the afternoon when Fujitsu, a Symantec customer, spoke about the payback from installing a hosted email filtering solution from Symantec. Before the installation, Fujitsu were receiving in excess of 2m emails per day. Between 90-95% of these emails were spam. After the rollout of the email filtering solution, Fujitsu are now receiving 5-10% of their previous email load per day. As a consequence they were able to reduce their email infrastructure from sixteen servers down to two. Furthermore, they were able to reduce their network link requirements and their storage requirements for email. And finally they were able to free up IT resources who previously were tasked with managing the email infrastructure. This is a big Green win!

My Symantec Vision 2010 conference badge

Later in the afternoon I was especially heartened to have a one-to-one session with Symantec VP of Global Solutions, Jose Iglesias. Jose is the guy raising/waving the Green flag within Symantec. He informed me that Symantec have used their own technologies to reduce the electricity bill in their data centers by $3m (10%) per annum!

How do they do this?
Symantec has software for helping manage computer clusters which can help you reduce the number of computers in a cluster without affecting your SLA’s.

Also, according to Jose, storage costs can represent between 25-75% of a data center’s energy spend. To help with this Symantec have storage management products which give deep visibility of use of storage. This can highlight overallocation, help reclaim storage space and defer the purchase of new storage.

Other technologies like dynamic storage tiering can significantly reduce the amount of energy used in storage while data deduplication can free up large amounts of disk space.

Symantec also have software which can put computers to sleep after a set period of inactivity and they have partnered with TechTurn to manage end of life computers

Finally, Symantec see a large role for themselves in helping secure the Smart Grid.

With all these Green credentials, why aren’t Symantec screaming their Sustainability story from the rooftops?

Possibly because they don’t see it as core to their customers’ needs. That is changing. Fast.

Another good reason for Symantec to strt talking up their Green credentials is that companies with a good record on Sustainability have an easier time attracting and retaining employees – something which is vital to the long-term sustainability of any company.

Utilities developing more of a customer focus

September 24, 2010 by Tom Raftery

I attended the SAP for Utilities conference earlier this week in Huntington Beach and I have to say I am impressed by the progress American utility companies are making towards being more customer centric!

The event was titled Sustainability for the New Energy Era and there was a full track dedicated to Smart Grids (obviously I attended almost all of the talks in this stream).

Attendance at the event was surprisingly strong with around 800 delegates despite the current economic woes.

This is the third SAP for Utilities event I have attended and I have to say I was very pleasantly surprised at this event by the number of times customer needs were referenced. Almost all of the Smart Grid talks mentioned the need to involve consumers in the process. Obviously, this is a point I have been banging on about for some time, but it is fantastic to see that the utilities are starting to finally get the message.

One of the best presentations of the event came from Paul Lau of the Sacramento Municipal Utility District (SMUD). SMUD is very unusual amongst utilities in its fanatical focus on its customers – from its About page:

For each of the last eight years, SMUD has received the highest customer satisfaction ratings of any utility in the state in the J.D. Power and Associates survey. SMUD received the second-highest score in the nation for commercial customer satisfaction in 2010.

One reason for this is that Sacramento Municipal Utility District is a community owned electric utility governed by a seven-member elected Board of Directors. SMUD are far from being unique in this model. During Paul’s talk he highlighted other reasons why SMUD is so popular amongst its customers.

SMUD take customer feedback very seriously – in fact, they solicit it. SMUD holds regular focus groups of their customers to find ways they can improve their offerings.

Also, the Board of directors goes out and holds meetings in the community to educate customers about the need for smart grids and consequently they don’t incur any of the blowback which plagued PG&E’s efforts in this area.

Paul commenced his address by paraphrasing Bill Clinton and saying that utilities need to realise that “it is the customer, stupid!” Now, coming from a utility co., that is refreshing!

Lastly, SMUD uses the term customers, not consumers or worse, ratepayers, as many utilities do. Just that slight shift in the lexicon says a lot about how SMUD prioritises its clientbase.

Utilities could learn a lot from SMUD’s focus on the customer – the good thing is that judging from the conversations I had at the SAP for Utilities event, the tide does appear to be turning in that direction.

IBM Summit’s first three days? – a great Start!

September 13, 2010 by Tom Raftery

I attended the first three days of IBM’s Start summit last week and I’m definitely going back this week for more.

The venue (Lancaster House) is a sumptuous mansion in the centre of London whose opulence, defies description!

The event kicked off with a day dedicated to discussing Smarter Cities. The speaker list included Martin Powell (Boris Johnson’s Advisor on the Environment), Nigel Hugill (Chair of the board, Centre for Cities), Hamish McRae (Associate Editor, The Independent), and Emma Harrison CBE (who seemed a little out-of-place to be honest!).

IBM's Ginni Rometty spaeking at IBM Start

The audience on the day included several chief executives of cities, the talks (especially Martin Powell’s Achieving a Sustainable 21st Century City Environment) were incredibly interesting, and the networking was tremendous.

Day two was Smarter Energy for a Sustainable Future. This was by far the best of the three days I attended, which says a lot considering how good the other days were! Again, the speakers (incl Charles Hendry (UK Minister of State for Energy and Climate Change), Martin Lawrence, (MD, EDF) and Rachel Fletcher, Director Distribution, Ofgem) and the audience were stellar but two things made this day stand out for me: 1) there was far more audience participation encouraged than either of the other two days and 2) most of the discussions were about Smart Grids – a topic I have had a deep interest in for some time now.

Day three was all about Smart Transportation. Once more the delegate and speaker lists were stratospheric. Speakers included Philip Hammond (UK Secretary of State for Transport), Ken Livingstone (former Mayor of London who introduced London’s Congestion Charge), Prince Charles (Prince of Wales and one of the initiators of the event), Graham Dalton (Chief Executive of the Highways Agency) and Len Porter (Chief Executive of RSSB) and Keith Ludeman (Group Chief Executive, Go-Ahead Group). Unfortunately, as I was flying home, I missed most of the afternoon sessions of the smarter transport day (and no, the irony is not lost on me!) but the morning discussions were fantastic.

Jim Steer, Director, Greenguage 21 at IBM Start

Two things which appear not to have been covered during the Smarter Transport day were sections dedicated to shipping (though this may be covered in the Smarter Supply Chain day) and walking/bike schemes.

A few critiques – the event is being held under the Chatham House rule which, while it is supposed to foster freer discussion at the event, it stifles reporting of the event subsequently. Also, the connectivity (even 3G) at the event is ery poor – probably a consequence of the building being owned by the UK Foreign Office and finally, there was no beer on offer at the reception – only wine!!!

If those were my only gripes with the event, you know it was good. The most impressive thing for me from the three days was the fact that no speaker (IBM or otherwise) mentioned a single IBM product. This was not a sales oriented event.

I’m back again for days seven and eight and I’m really looking forward to more of the same. Well done Caroline Taylor and the IBM team.

1.25 Gigawatts of Solar Thermal Power Approved in California in Past Two Days Will Double US Capacity

?There?ve been multiple gigawatts of solar thermal power plants planned for various places in the California desert for some time, but finally some more of them are getting the approvals need so that construction can start: The US Bureau of Land Management has issued a final environmental impact statement for the 1,000 MW Blythe Solar Power Project; and the 250 MW Beacon Solar Energy project has received final California state approval as well.
The smaller of the two first: Renewable Energy World reports NextEra Energy Resources has been given the green light by the California Energy Commission to begin construction on the 250 MW Beacon Solar Energy project.
Green roofs offer antidote to urban heat island effect

Researchers at Columbia University have demonstrated that a layer of plants and earth can cut the rate of heat absorption through the roof of a building in summer by 84%

Perhaps the greatest overall benefit of green roofs comes in tackling the “urban heat island” effect, which Gaffin suggests is responsible for two-thirds of New York’s localized warming over the last century. The conventional black rooftops that he calls “tar beaches” are major contributors to this phenomenon, absorbing and re-radiating the sun’s energy as heat. “We’re going to want to cool regional climate down, especially where people are living,” Gaffin noted. “So we’re going to have to confront the urban heat island effect.”

While conventional roofs can reach temperatures of 80 ?C at 1.00 p.m. even outside of high summer, green roofs always stay closer to ambient temperatures. “These [conventional roofs] are almost dangerously hot spaces,” Gaffin told environmentalresearchweb. “That’s a huge heat load that we can get rid of.”

Plants in green roofs regulate their temperatures through evapotranspiration. “They evaporate copious amounts of water,” Gaffin explained. “That takes a lot of energy and means it’s a great way to stay cool.”
Creating 625,000 jobs and saving $64 billion through energy efficiency

Energy efficiency is THE core climate solution. It’s the biggest low-carbon resource by far. “Efficiency Works” [PDF], a major new report by Bracken Hendricks, Bill Campbell, and Pen Goodale, finds that a straightforward set of policies aimed at upgrading just 40 percent of the residential and commercial building stock in the United States would:
1. Create 625,000 sustained full-time jobs over a decade.
2. Spark $500 billion in new investments to upgrade 50 million homes and office buildings.
3. Generate as much as $64 billion a year in cost savings for U.S. ratepayers, freeing consumers to spend their money in more productive ways.

Carbon markets: HFC-23 – The smoking greenhouse gun

ONE of the curiosities of carbon markets is that they do not just trade in carbon. Other greenhouse gases can be given a value, too?sometimes a very high one. Claims that these prices promote scammery are now prompting some searching questions.

The gas at the centre of the controversy is HFC-23, a greenhouse gas which, on a weight-for-weight basis, is 14,800 times better at trapping heat than carbon dioxide. HFC-23 is produced as a by-product of the manufacture of HCFC-22, an ozone-destroying refrigerant. HCFC-22 is banned in developed countries, but developing countries can keep making it until 2030.

The acronyms do not end there. Under the Clean Development Mechanism (CDM) of the United Nations HCFC-22 producers in developing countries that destroy, rather than release, their HFC-23 can be eligible for Certified Emission Reduction (CER) credits, which can then be traded in the European Union?s emissions-trading scheme. This allows companies to buy extra emissions reductions to meet their cap-and-trade obligations, and in so doing to transfer money to schemes reducing emissions in developing countries.

Iberdrola Renovables wins contract for nine wind farms in Brazil

Iberdrola Renovables, in consortium with Neoenergia, has been awarded the contract for nine new wind farms in Brazil, with total installed capacity of 258 MW. It is the second contract to develop renewable energy that the company has won in Brazil.

The contract award took place in Rio de Janeiro, during the second tender process for renewable energies in the country, organised by the Agencia Nacional de Energ?a El?ctrica (Aneel).

Iberdrola Renovables has committed to supply the electricity generated at these facilities to the Brazilian government for a 20-year period, starting in January 2013. The annual amount of the contract awarded yesterday by Aneel is about ?60 million (130 million reales).
Santa Cruz Mountains redwoods lure cash for trapping carbon

PG&E is handing over tens of thousands of dollars to the nonprofit Sempervirens Fund to protect a 425-acre stand of redwoods once slated for logging deep in the Santa Cruz Mountains.

The deal, expected to be completed next month, is part of the utility’s efforts to combat greenhouse gas emissions, in this case safeguarding trees for carbon absorption, and is helping to drive a new marketplace where people and business are offered an incentive to offset pollution.

“We’re finding a new financial model here for doing things to capture greenhouse gases that wouldn’t have been done otherwise,” said Robert Parkhurst, climate protection and analysis manager for PG&E.

“It’s a new paradigm for protecting the environment.”
More firms in carbon trade setting up shop in Singapore

More companies trading in carbon offsets and those financing emissions reduction projects are setting up shop in?Singapore.

More than 30 such carbon-related firms have done so in the last three years or?so.

The trade in carbon credits, worth US$153 billion (S$208 billion) globally last year, is driven by various requirements to cut back on greenhouse gas emissions. These include cap-and-trade regulations in Europe and countries scrambling to fulfil carbon emissions obligations under the United Nations? Kyoto Protocol.
Exelon Grabs John Deere?s Wind Projects for $860M ?

And you thought John Deere was all about tractors. This morning utility Exelon said it will buy up the wind power division of John Deere, called John Deere Renewables, for $860 million, plus an additional $40 million once all of the projects are completed. John Deere Renewables has 965 MW of clean power projects under development in various stages.
New Filter Could Make LCDs >400% More Efficient : TreeHugger

The immensely popular LCDs screens that are found everywhere in the modern home (television, computer, laptop, cellphones, etc) use less energy than CRTs, the previous technology, but they are still far from being optimally efficient. Only about 8% of the light emitted by a LCD’s backlight makes its way out, and the rest is wasted. But that might be about to change thanks to a new filter that could boost that efficiency by more than 400% and allow around 36% of the light to pass through.

The zero-emissions Nissan Leaf test drive

August 31, 2010 by Tom Raftery

I love the idea of electric cars and have done for a long time.

Recently, one of my best friends Ray Flynn, proprietor of Flynns Garage (a Nissan Dealership in Carlow, Ireland), contacted me to let me know he is one of only 15 Nissan dealerships in Ireland who have been approved to sell the new all-electric Nissan Leaf. As such he had a limited number of slots available for a test drive and he wanted to know if I’d like one of them. I jumped at the chance!

The Leaf is a totally electric car relying completely on its 24 kW?h/90 kW lithium ion battery pack for power. The battery pack is rated to deliver 100 miles on a full charge but this can vary from about 62 miles (100 km) to almost 138 miles (222 km) depending on driving style, load, traffic conditions, weather (i.e. wind, atmospheric density) and accessory use.

Nissan Leaf under the hood

The car is a five seater with a spacious interior. It is very responsive to drive. My own car is a 2008 Toyota Prius and this is a much nippier car than the Prius. It handles well on the road and because there are 300kg of batteries under the floor, the car sticks to the road on corners!

Charge time varies on the type of charging (normal or fast) and whether the battery is fully depleted or only partially. Using a standard 220/240 volt 30 amp supply the battery can be fully charged in 8 hours. Fast charging using a 440V level 3 charger charges to 80% in around 20 minutes – these are typically the kinds of chargers you will see deployed in places like McDonalds, Tesco’s and motorway caf?’s I assume.

Nissan Leaf interior

There is a lot of technology built in to the car. It is connected to a global data center which provides support, information and entertainment at all times. The GPS navigation system delivers a constantly updating display of your range as well as showing all the charging stations on your route and it allows you to book a charging station to ensure that it is available when you arrive.

Mobile phone apps will allow remote turning on of aircon and heating as well as setting charging times to coincide with time of use rates from utilities. The advantage of turning on aircon/heating before getting to the car is to have it pre-heated/cooled while still connected to the mains to save on battery life.

Nissan Leaf rear spoiler with solar panels

It has a spacious boot and there is an option to get a rear spoiler with solar panels to trickle charge the auxiliary 12 volt battery, though, tbh this feels like a bit of a gimmick!

In terms of the main battery, Nissan has announced that it will warranty the battery pack in the Leaf for 8 years or 100,000 miles after which time Leaf batteries will still hold around 70-80% of their rated capacity. I suspect that there will be a significant market for slightly depleted car batteries at that point for home energy storage to better enable load shifting and smart grid applications.

The car I was driving is a pre-production model. Because the production lines are only now being set-up, this one was hand-made and is insured for a replacement value of ?1.2 million! Consequently I drove it very carefully.

Conclusion: The Nissan Leaf is the future of motoring, no doubt. It is fast, affordable and very cheap to run. And that’s not taking into account at all, the environmental advantages of running a zero emissions car! Sure, there are limitations to having a car with a 100 mile range – most of these will be overcome by the roll-out of networks of fast-charging stations. After this test drive, I have no doubt that when it comes time to replace my Prius, my next car will be all-electric.

The Leaf goes on sale in Ireland in February 2011 at a price of ?29,995 (after a ?5,000 govt subsidy), in the UK in March 2011 for ?28,990 and in the US in December for US$32,780.

And finally, if you are interested in going entirely zero-emissions with your motoring, my buddy Ray (mentioned above) has partnered with a solar panel company and they are able to offer a Nissan Leaf and the solar panels to charge it from. Now that’s serious awesomeness!

And here, after a short break, are this week’s Green Numbers:

US wind energy usage grows by 28%

Consumption of electricity from wind rose by 28% between 2008 and 2009, according to the federal government’s annual energy report.

Spanish companies have 9,210 MW of installed wind power outside Spain

The installed capacity of Spain increased by 2,459 MW in 2009, reaching a total of 19,149 MW (these figures include both the activities of national and international operators). This way, wind energy rose as the third technology of the system with demand coverage of 14.4%, reaching peaks of over 50% on certain occasions.?

Three firms control 89% of US soft drink sales

Three firms control 89% of US soft drink sales. This dominance is obscured from us by the appearance of numerous choices on retailer shelves. Steve Hannaford refers to this as “pseudovariety,” or the illusion of diversity, concealing a lack of real choice. To visualize the extent of pseudovariety in this industry we developed a cluster diagram to represent the number of soft drink brands and varieties found in the refrigerator cases of 94 Michigan retailers, along with their ownership connections.

?200m wind farm for Co Clare

Clare County Council has given the go-ahead for construction on the largest community owned wind farm development in Ireland.

The ?200 million project will see West Clare Renewable Energy build 28 3MW wind turbines on a mountain slope between Ennis and Miltown Malbay, and will generate enough power to cover every home and business in Co Clare. Construction of the project will generate up to 300 jobs.

Indian Point Nuclear Plant?s Toll on River Stirs Debate

Just beneath the wind-stippled surface of the Hudson River here, huge pipes suck enough water into the Indian Point nuclear plant every second to fill three Olympic swimming pools. And each second they take in dozens of organisms ? fish and crabs, but mostly larvae ? that are at the center of a $1.1 billion debate: should the plant have to put in cooling towers that would vastly reduce the intake of water?

The Many Benefits of Smart Grid Investment

A chain is only as strong as its weakest link.? A power grid is only as secure and reliable as its most overloaded and vulnerable distribution areas.? A single point of failure can interrupt power for thousands, even millions of customers.? This flaw in our grid is becoming more apparent as electricity demand has increased quickly over the past few decades.? Since demand is outpacing the available supply of electricity generation capacity, power grid failures are becoming more common, but this need not be the case.? Smart grid technologies can efficiently schedule and redistribute electricity usage, smoothing the demand curve and reducing the peaks.? If we invest in smart grid technology, automating the detection of grid malfunctions before they become catastrophic, we will save billions of dollars a year.

CSC Baseline Data: Server Productivity – 4.7% of servers totally unproductive

As we collected baseline data for our first and second group of servers, we have been able to pull together some initial reports for our NightWatchman Server Edition case study environment.? Taking into account that we have a few servers that are not yet up and running with the software, it is worth noting that these are preliminary reports, but it is interesting to see what the data will look like and how it will help us begin to develop a plan in order to put the data to best use.
In this blog we?ll share the first set of reports around server utilization.?Here is the information we pulled from the tool around our pilot servers:

China’s 45 Billion Disposable Chopsticks Require 100 Acres of Forests Every 24 Hours

Apparently China’s Ministry of Commerce has had it with disposable chopsticks. It sent out a warning to chopstick makers in June to warn them that: “Production, circulation and recycling of disposable chopsticks should be more strictly supervised.” The reason? With about 45 billion disposable chopstick pairs made every year in the country, or about 130 million a day, a lot of wood is being wasted, and that in a country that is trying to increase its forest coverage (from about 8% in 1949 to 12-13% today, compared to 30% for the USA).

Symantec’s Sustainability Story: It’s The Power Consumption, Stupid.

July 23, 2010 by James Governor

I was lucky enough recently to meet Jose Iglesias, the guy spearheading Symantec’s sustainability efforts. I wrote the interview up over on Monkchips, but much of the content belongs here too. I like Symantec’s clear focus on energy. While others are broadening their sustainability story, Symantec is doubling down on managing energy more effectively, with a plan to take its expertise in reducing IT power consumption and start applying it to broader Smart Grid demand response.

Symantec?s Green IT story is very much an enterprise play and arguably a solid sustainability product strategy could help to increase visibility for some of Symantec?s enterprise tools. Thus for example ? Symantec NetBackup PureDisk for storage deduplication could be used to cut the amount of storage and power. One challenge for Symantec is identifying and serving the new buyers in energy reduction. Most of the firm?s traditional practitioner purchasers are not tasked with reducing the energy footprint of the products they manage?.

?We sell to admins, but few get compensated on energy savings?

To which I would say? not yet.

Smart Grid as Game Changer

One major opportunity for Symantec to change the account management game there is to parlay its IT experience directly into related spaces such as Smart Grid security and asset management. I knew before the briefing that Symantec is having some early success in the Smart Grid market selling, for example, cryptography. Security is a major issue overhanging smart grid and remains a key selling point.

I am not a fan of FUD though it certainly works. But let?s get real. In Europe for example we?re getting all excited about the need for smart grid standards to prevent tampering with our energy supply. Yet Russia could turn off a gas tap and we?d be screwed within weeks, no smart grid required. Whichever way you look at it ? energy reduction is going to be very big business indeed. The tail is starting to wag the dog.

So Symantec has plenty of potential upside in Green IT near term, and smart grids longer term. If you’re interested in learning more about the company’s efforts and products in energy efficiency check out the Monkchips post, which also talk to the fact the firm needs to improve its sustainability reporting in order to have a stronger voice in the sustainability conversation. I know many of you are CSR reporting nuts…
