What is Student Switch Off?

Student Switch Off is a NUS led initiative aiming to bring collective energy saving action to university accommodation across the country. This could be through simple actions like switching off lights to longer, larger campaigns. So far this year SSO has reached 139,000 students over 44 universities leading to an average of 5.5% reductions in energy use (keeping roughly 1,188 tonnes of CO2 out of the atmosphere).

How did King’s Accommodation do?

Over the past year KCL Halls of residence (specifically Stamford Street Apartments, Great Dover Street Apartments, Wolfson House and Champion Hill) used 4.3% less energy compared to the 2014/15 academic year. That’s the equivalent of 76 tonnes of Carbon Dioxide being kept out of the atmosphere.

Did you say Ice Cream Giveaway?

Why yes. As Great Dover Street saw the greatest reduction in electricity use amongst the halls they were treated to roughly 400 tubs to free Ben and Jerry’s Ice Cream (as well as some vegan options and sorbets). With help from the RLAs (Resident Life Assistants), Neil Jennings, who set up the Switch Off programme, was able to pass on all that ice cream to GDSA students, a brief but welcome respite in the middle of exam season.

KCL Sustainability: Green Labs

While King’s has been greatly investing in its broad sustainability agenda, there has also been a drive to innovate in our laboratories. Despite covering just over 10% of our floor space, our labs are spread across all 4 campuses and use a disproportionately large amount of energy and water, as well as produce dangerous chemical waste.

To address this untapped area, Kings has invested in over the past 18 months in a post to lead in this area as well as invested in the projects highlighted. Here are just some of the scheme’s we’ve recently implemented to improve the efficiency of King’s labs.

 Savawatt Installations

This £38,000 installation project saw 584 Savawatt controls being installed into our research fridges and freezers which saves about £15,000 each year (and roughly 68 tonnes of CO2) meaning it pays back its cost in about 2.5 years.

Green Impact: Lab Sustainability Champions

Just like in our King’s offices, our lab staff take part in an awards programme which helps reduce energy, water and general waste across the labs. They also get audited for their work at the end of greeni_logoeach year for an award promoting an environment of commitment to sustainability.

This year 20 teams are participating which is the most laboratory teams for any university in the UK.

Drying Cabinet Exchange

33 old uninsulated drying cabinets were consolidated and replaced by 28 insulated efficient models, paying back our investment in 4 years and achieving £15,000 of annual savings.

blogfumecup Fume Cupboard Management Policy

Already applied to new fume cupboard installations, this technical policy will take over a year to implement but will result in hundreds of thousands of pounds saved!

Cold Storage Policy

Our laboratories are subject to a ‘Cold Storage Policy’ which is used at other universities such as Oxford amongst others. This promotes efficient, safe and sustainable practise for using the research laboratory fridges and freezers.

Current/Future Endeavours

  • Continued installation and refurbishment of fume cupboards and ventilations systems
  • Introduction of Warp-it system for redistributing unwanted resources warpitamong other institutions such as UCL who have been very successful with the system
  • Joint UCL/KCL procurement mini-tenders

 More to come!

Look to our case studies on our labs page for summaries of all the above projects and plenty more to come, including a variety of small projects lead by local lab staff (timer installations, equipment exchanges, UPS installation, freezer warm-ups, waterless condensers and more).

King’s Sustainable Lab Awards

Last week the Sustainability team hosted the first ever KCL Lab Sustainability Awards. These awards are a part of the NUS Green Impact awards with a focus on research laboratories, and utilise the S-Lab environmental assessment framework to evaluate labs for their efficiency and sustainability. 10 teams participated in the awards; the most teams in England. 8 won bronze and the other 2 teams commendably won silver, as the long-term goals are for incremental effective improvements which are user driven.

A host of positive actions were taken as a part of these awards. Martin Farley, (Research Efficiency Officer and lab-awards manager) spoke of some tissue culture labs at FWB managed by Beatriz Padilla (PhD candidate). Their ULT freezer was almost full and they were either about buy a new freezer or out source for space. Instead they decided to defrost there ULT freezer as a part of the awards. They managed to create ~40-50% more space, audited the samples they had, and put less strain on the freezers compressor by cleaning the dirty filter. Not only did they avoid purchase and running costs of a new ULT freezer, they saved on the one they owned.

Worth mentioning are the two silver teams: Dr. Bernard Freeman (Lab Manager) and Sandhya Anantharaman (Research Technician) helped SGDP achieve a silver award with their in-house designed online lab management tools. Women’s Health also commendably achieved silver through their note-worthy engagement and shared plans to re-engage with the awards next year. Dr. Pamela Taylor-Harris of the Women’s Health Team (also including Cally Gill and Rima Patel) stated “Women’s Health were definitely inspired by lab sustainability and I’m sure would like to take part again and continue to improve practice in the future.”.

Next year the aim is to grow the number of teams participating, and aid the repeating teams to achieve new and improved goals in an aim to bring all labs to a Gold standard. Look to our website for more details and updates about what is going on, or contact Martin Farley or the sustainability team at sustainability@kcl.ac.uk.

Looking at Display Energy Certificates at King’s

This week we’ve been talking to Tom Yearley and Bolaji Olaniru, (who look after energy at King’s), about DECs around King’s and how these help monitor the energy performance of our buildings.

Display energy certificates (DEC) were introduced to improve the energy performance of buildings and are used to display the actual energy performance of a building. Since January 2012, all public buildings with total useful area of more than 500m2 are required to display DEC in a place clearly visible to the public. This means that a lot of the buildings across King’s are now required to have a DEC on display.

DEC displays the Operational Rating (OR) of a building ranked from A-G, with “A” being the most efficient and “G” the least. This rating shows the amount of energy consumed by a building, calculated by comparing the value of carbon emissions per unit area with other buildings in the same OR category. Other metrics of a building are considered for the OR rating, including building category, location, unique property reference number, energy consumption, measurement period and total useful floor area. DECs are accompanied by an advisory report (AR) that helps the occupier to identify what may be done to improve the energy efficiency. The DEC is valid for 1 year and the AR is valid for 7 years in buildings over 1000 m2. For smaller buildings (between 500 m2 and 1000 m2) both the DEC and AR are valid for 10 years.

At King’s we currently manage 26 buildings which have DEC certificates. Within these buildings, nine have a rating of C (no As and Bs!) and four buildings are rated as ‘G’. As this shows a lot can be done to improve the energy performance of our building.

Currently within the Sustainability team we are focusing on two main methods to improve of energy efficiency: capital investments and behavioural change. Capital investments can help to make infrastructural change which can have a large positive impact on energy performance. However these projects are quite expensive and will require more labour and time to implement. Behavioural change therefore can have a huge impact on our energy use at King’s – and it’s free! These are the little things we can do as individuals, such as switching off electrical appliances, wearing warmer clothing in winter and using the stairs.

As a team we are working hard to try to improve our energy performance and are currently running a number of behavioural change programmes, including Sustainability Champions. You can make a difference so get involved! Contact us for more details or sign up to our newsletter to stay up-to-date with our future projects.

A Clash of Titans: The Principal’s Debate on fossil fuel divestment

[This guest post comes courtesy of Justin Fisher, a former Masters student and alumni member of KCL Fossil Free. The views presented do not necessarily reflect those of King’s Sustainability]

Last Wednesday marked an important day for King’s as President and Principal Ed Byrne hosted his first Principal’s Debate. This was in response to King’s Fossil Free campaign, which has for more than a year been increasing support for its motion asking the College to divest Debate_Pic_1itself from the fossil fuel industries. For those who have not followed the progress of the campaign, it really kicked off in October with the submission of a 1200 signature petition to the university administration. While that number has since increased to over 1400, the university finally declined the divestment option formally in mid-February. However, much to King’s credit, the Principal’s Debate went ahead as scheduled, and it made for a most lively and engaging evening, and further demonstrated the scope of the passionate support for divestment at King’s.

The question at hand was, ‘Is divestment from fossil fuel companies a useful policy tool to bring about action on climate change?’ Representing the College on the ‘no’ side were King’s VP of Research & Innovation Chris Mottershead and King’s Professor of Climate & Culture Mike Hulme. Speakers on the ‘yes’ side included Mark Campanale, co-founder of the Carbon Tracker Initiative, and Mark Horowitz, a PhD candidate in neuroscience at King’s and one of the initiators of King’s divestment campaign. Each speaker was allowed to make their case before fielding questions from the audience and making some final rebuttals.

Chris Mottershead has been in close contact with the campaign for months, and it was to him that the petition was given back in October. Interestingly, Mottershead has spent the majority of his career working for BP, and he has perhaps unsurprisingly been weary of endorsing divestment at King’s. In his remarks he focused attention on the role of governments in owning and controlling the majority of carbon reserves, seemingly trying to make the case that fossil fuel companies are not the ones driving fossil fuel extraction, and the role of consumer demand. He was also careful to focus on the global need for fossil fuels, and reiterated time and again the need for consistency in the ways King’s invests. However, he admitted that he does not believe that King’s has any current investments in renewables. One of the most powerful concessions of the debate came when an audience member bluntly confronted Mottershead with the question of whether his three decades of experience working with BP created a conflict of interest with the divestment question. Mottershead responded that it ‘probably’ did. He also compromised his position when he claimed, late in the debate, that fossil fuel companies don’t actually have much political power, which drew loud jeers from the audience. Clearly the crowd was not buying what Mottershead was selling, though few would deny the importance of government action. Indeed, that is one of the primary aims of the divestment campaign.

Professor Hulme proved a welcome and intriguing addition to the panel. A Nobel-laureate for his work with the IPCC, his experience working with climate change is beyond question, and his academic approach to the topic provided a lot of interesting debate and easily provoked the majority of the questions from the audience. Hulme carefully explained the importance of economic development in the poor world and technological innovation in mitigating the worst impacts of climate change, and continually reiterated that reducing the question of climate change to carbon emissions is an oversimplification. He offered a reminder of the range of challenges brought about by climate change, and explained why he preferred a broad approach with multiple targets. He was also fixated on the semantics of the question, as he reiterated time and again that he did not believe that divestment was a useful policy tool, nor did he believe that it would bring about what he believed to be the necessary range of actions to address the myriad problems posed by a rapidly changing climate. However, when he eventually conceded that divestment may well be a useful tool for social mobilisation, there was a noticeable buzz of excited exasperation from the crowd. Indeed, it seems as though few of Hulme’s points were incompatible with the aims of the fossil free campaign, and he did offer an important reminder of the complexity and diversity of the issue.

Mark Campanale offered a level and analytical approach to the question, which is not surprising given his role in helping to found the Carbon Tracker Initiative. It was Carbon Tracker that first coined the term ‘carbon bubble’ and explained its implications; if the world takes action to limit global warming to below 2°C, in any form, then as much as 80% of Debate_pic_2known carbon reserves will be left in the ground. Given that fossil fuel companies are valued largely on the reserves they hold, these so-called ‘stranded assets’ would rapidly sink such companies and lead to a crisis similar to that when the US housing bubble burst in 2008, only far worse. That bubble was worth a staggering $2.8 trillion. The value of the carbon bubble? An unfathomable $28 trillion. Campanale explained carefully the financial folly in continuing to invest in companies whose future projects are all but guaranteed to lose money, providing a sound financial case for divestment.

Mark Horowitz was the final speaker and he made the most of his time, deftly covering a range of issues from scientific projections of the effects of increased carbon emissions to the advent of grid parity in much of the poor world (where renewable power has become a more affordable option than fossil fuels) to the political obstruction of fossil fuel companies undermining climate regulations. He patiently explained that the position of the campaign is not a radical one; rather, that of companies’ intent on burning far more carbon than is known to be compatible with life on this planet is as radical as it gets. He offered an impassioned and logical approach and against Mottershead and Hulme’s assertions that fossil fuel companies provide a social good, asked at what point does the negative begin to outweigh the positive, bringing about the need for a change in the balance of power? Horowitz asserted that perhaps the decades of experience on the other side of the table had fostered a complacency towards the status quo when what is needed more than ever are fresh perspectives.

The most engaging part of the evening were the audience questions that came after each speaker made their case, some of which have been alluded to above, which lasted for more than an hour. The general mood of the room was encapsulated in an assertion from an audience member that they had no doubt that King’s would eventually divest, and the real question was whether it was going to be a leader or a laggard. Indeed, with other London universities such as SOAS and LSE setting formal processes to work on the question, King’s is already looking more like a follower than a global leader.

The debate ended with Ed Byrne asking the audience to show its support for one side or the other by way of applause. The thunderous racket in support of divestment, accompanied by a visual show of support with audience members holding the Fossil Free logo, boisterously summed up the excited pro-divestment sentiment of the crowd. The debate offered a tremendous platform for both sides to explain their stance, and a lot of genuinely useful dialogue was generated as a result. At the end, though, one could not help leaving feeling as though support for divestment is growing. It was good of King’s to participate in such an event, and we shall now wait and see how well the administration was listening.

King’s Unplugged Results

Thanks to those that helped with King’s Unplugged as part of Green Week on Friday 13th February. The results are now in and we managed to reduce energy consumption over the weekend by 13%, equating to over 4 tonnes of CO2 and around £978! This is a great achievement and show that small actions, such as turning off your PC at the end of the evening, can make a huge difference!

Sustaining our climate: taking the initiative

[This week’s guest blog comes courtesy of Joanna Peasland, a first-year Geography undergraduate. The views presented do not necessarily reflect those of King’s Sustainability]

JP_4

2nd October 2014. Copenhagen, Denmark. The IPCC Synthesis Report is released.

The Guardian’s article: “IPCC: rapid carbon emission cuts vital to stop severe impact of climate change” contextualises this latest release of the Panel’s current state of affairs with regards to global environmental change with an unambiguous sense of urgency.

The overriding message is not a new one, but demands to be received with more gravity than it has previously: the effects of climate change are becoming increasingly pervasive, and pose irreversibly dangerous risks unless we reduce carbon emissions to zero and rapidly integrate sustainable energy sources into society. Moreover, the technological and the economic feasibility of switching to alternative sources of energy is now being justified by this united global voice in preparation for much anticipated climate talks in Paris next year.

It goes without saying that release of the most comprehensive report on climate change since 2007 has pushed this environmental issue to the forefront of media coverage. Governments, institutions and populations are divesting in fossil fuels and investing in renewables. This ultimately has one of the two consequences for the future: our planet will descend further toward catastrophic changes or it will benefit from the mitigation of such changes. What follows is a selection of some of the items that have caught my eye during the first semester of the academic year – paved with problems but equal promise. They highlight some of the more ambitious movements towards a revolution in energy policy and a more sustainable future, at a time – seemingly to me –  when the debate about global climate change has never been so exhilarating!

Wind power

Browsing through various newspapers’ online ‘environment’ sub-sections led me to an inspiring read on Denmark’s progression in transforming their energy economy in the New York Times by Justin Gillis; A Tricky Transition From Fossil Fuel: Denmark Aims for 100 Percent Renewable Energy. Gillis discusses the feasibility of the country’s target of eliminating fossil fuels from the energy mix by 2050: a goal which really does set the benchmark for carbon emissions reductions worldwide. This is a country where already, more than 40% of their grid is fed by renewables. These targets however, do not come without their costs. I picked up on one point in particular: Gillis writes of a somewhat imposing ceiling on the Danes’ smooth sailing to sustainable success – the economics of it all. Intermittent wind power makes the country potentially extremely vulnerable, therefore some traditional power plants are favoured as a support system in the event of a blackout that are propped up with various subsidies. These power companies cannot sustain this because their profits will eventually stagnate. International imports of energy bring additional predicaments in the form of the simple ‘ripple effect’ of relying too heavily on outside sources and a potential monopoly game that could play out with increasingly asymmetric power relations. As Gillis suggests, a re-design of the workings of the energy market is required. Perhaps this is as important as the switch to renewables itself. Much like new models of manufactured goods, its accessories, its ‘supporting infrastructure’, must adapt and progress also in order to harmonise with changes of the product itself.

It would be foolish not to mention the agreement pledged by Mr Obama and Chinese President Xi Jinping, aiming to reduce carbon emissions below 1990 levels back in November. A deal well received by a wider community; US climate negotiators (apparently) received great applause for it during the climate talks at Lima in early December. Tim McDonnell’s piece for Climate Desk –  Obama’s Deal With China Is a Big Win for Solar, Nuclear and Clean Coal – offers a useful appraisal. China is now compelled to firmly hold its place as the world’s frontrunner of the renewable energy sector, through a requirement to source an amount of energy equivalent to the entire electricity grid of the States, entirely from renewables by 2030, as it now has commercial backing from the US. Coupled with caps on emissions and further cuts in the US, this progression will clearly be mutually beneficial for both countries and for the greater good of the environment.

JP_3

An implication of the new deal is undeniably the eventual rise of cost for the US as a net energy importer as the stock prices of solar power will escalate as it is integrated into China (exactly when and how much by is largely undefined as of yet). But, to grossly oversimplify the situation, the US has now publicised its seemingly increased support for China’s technological advancements, thus the optimist in me is hopeful for the future energy relations between the two powerhouses. With massive carbon capture and sequestration and nuclear plans also on the agenda, McDonnell writes of the hoped geopolitical ease of this deal relative to global scale, legalistic treaties.

Of course, there is internal contention brewing within Congress. Appropriately dubbed ‘climate deniers’, Republicans have reacted badly as their bone of contention claiming that China is unwilling to take steps to cutting emissions has all but been demolished in the wake of news of the talks. The Guardian writes of the backlash such as threats to implement continual legislative walls to Obama’s green promises by the likes of Republican speaker of the House John Boehner. There is certainly no easy route to changing the national behaviour and organisation of the US energy system, to put it lightly.

As I write, the year (2014) is drawing to a close yet anticipation for change is hanging high. News of daily developments flood my social media timelines as leaders in governance from all corners of the globe have spent two weeks negotiating climate at the UN 20th Conference of the Parties in Lima, Peru. The Green Climate Fund has reached its first milestone with vast contributions from both some of the most advanced and emerging economies alike. Even Australian leader, Tony Abbot, pledged 200 million dollars (AUS). The fund is a “start” to addressing the problematic relationship between developing nations and exploitation of fossil fuels, writes The Climate Reality Project activism blog. My question is how exactly it will be distributed and who will be the most favoured recipients of this fortune?

Does the hype surrounding such global efforts cloud worrying developments that directly combat sustainable initiatives? In the UK, George Osborne’s autumn statement favoured advancing the dreaded Shale Gas industry, granting 31 million pounds of taxpayers’ money for research drilling and an additional few million on “public engagement” writes Damien Carrington for The Guardian. Burying our heads in the sand, for better use of a cliché, and pursuing ‘less conventional’ fossil fuel route is neither clever nor safe – on many levels.

North Sea oil rig

An issue this pervasive is bound to leave me ignorant to the great complexities of the political and economic implications of these crucially needed sustainable initiatives. Rush the transition to renewables and entire industries come crashing down, not to mention the jobs within them, yet must we accept that sacrifice to some degree may be inevitable however we approach it? Problems are likely to greet us at every corner. However, these simple but beautifully witty and fiercely blunt words of Dr. Guy McPherson stay with me and reaffirm my attitude: “if you really think the economy is more important than the environment, trying counting your money while holding your breath”. The pragmatism being, of course, that climate change could not be more inconvenient to the economy. But it is this very inconvenience that makes it most certainly in our long-term interests to transform our energy habits. And transform we must.

Welcome back – a new year and new term

Welcome back to students and staff – we hope you have had a happy and sustainable holidays!

We are pleased to share with you that King’s reduced our electricity consumption by 43 per cent and gas by 24 per cent compared to normal December usage. The Sustainability Team would like to thank you for all reducing our electricity and gas consumption over the winter break. This resulted in savings of £73,000 and 338 tonnes of CO2. We managed to improve by 24 per cent against the winter break of 2012/13. This is a fantastic achievement but there is still room for improvement.

University-wide efforts are helping us to achieve our energy and carbon reduction targets. Shutting down unnecessary items, including lab equipment, lighting and PCs wherever possible led to this result. This builds on the success of the Blackout project in late 2014. This year we will be aiming to achieve similar savings every holiday, weekend and evening when non-essential equipment, such as lights and computers, are not needed.

Looking forward to the term ahead we have a jam-packed schedule. The Sustainability Champions project is set to officially launch next week, swiftly followed by Green Week, and Fairtrade fortnight. We are looking for enthusiastic people who would like to be involved at driving sustainability at King’s and helping with any of the former mentioned projects.

Fairtrade fortnight is especially important; we will be celebrating 20 years of Fairtrade, King’s is aiming to gain accreditation for being a Fairtrade university. The fortnight will be focusing on core commodities – cocoa, sugar and tea. This is the chance to take action to ensure marginalised farmers around the world have decent working conditions and are paid a fair price for their produce. Watch this space for the full Fairtrade fortnight schedule.

Let’s meet Tom, Energy Manager

So what does the Sustainability team actually do? You know we put together events like Blackout and the Sustainability Forum, and maintain this blog. But as important as these things are, they form only one part of what we’re up to. Our goal is to embed sustainability within King’s at all levels from operations and administration down to the actions of staff and students. One major focus of this work is energy, and this week we’ll meet Tom Yearley, our new Energy Manger, to gain some insight into what his role entails and what it means for everyone at King’s. So, Tom, what does the Energy Manager do?

Tom Yearley

The man himself, likely pondering how best to increase energy efficiency at King’s. Or surfing. He also likes surfing.

‘As Energy Manager at KCL and a professional environmentalist, my work involves minimising the environmental impact of the use of utilities at the University. This includes gas, water, electricity and oil. More widely the role involves influencing and reporting on the University’s carbon footprint, including broad factors such as travel, waste and procurement. Fortunately, sound environmental practice leads to financial savings and compliance with legislation which are also key deliverables for me. On a daily basis, I may have my head buried in a spreadsheet, be out and about engaging people in carbon reduction projects or completing energy surveys of buildings.

My primary challenge now is to accurately measure how and where we use utilities. This will enable us to demonstrate to staff and students exactly how great an impact they can have on not only the University’s environmental impact but also on its finances at an individual level.

I have enjoyed a varied career in the environmental sector over the past ten years. I have worked for private and publicly funded organisations including a chocolate factory, consultancies and upstream oil and gas. For the past five years I have been working in the higher education sector. Before KCL I was employed at the University of Reading. I passionately believe that the greatest contribution to a reduction in societies’ environmental impact can be made by responsible use of resources. This can be achieved in a variety of ways, including technological innovation and especially by changing the relationship individuals have with natural resources. Working at a university, I not only aim to influence our consumption directly now, but also hope to influence future leaders, providing a social norm for how business can be run with a minimal carbon impact.’

So, basically, Tom is an energy expert in a position to affect tremendous change. His top sustainability tip for everyone is to ensure that hot water temperature and timers are correctly set up at home. ‘Not only can this dramatically affect your carbon footprint,’ he explains, ‘it can also save you hundreds of pounds per year. It’s amazing how little changes that do not affect comfort levels can significantly alter energy consumption.’ And Tom knows his home energy; this year, he won an Observer Ethical Award for improving his own home’s energy efficiency. He also urges everyone to turn off unnecessary equipment that’s not in use at work (yes, he had a ridiculously fun time at Blackout).

If you’re interested in hearing more about Tom’s work and energy and sustainability at King’s, he happens to be participating in EcoSoc’s panel discussion tomorrow evening (see below for details). We hope to see you there!

Big energy savings over Blackout weekend

First things first: A huge thank you to all of the student and staff volunteers that joined us for some serious energy-saving escapades (and a shout-out to those who helped by powering down their rooms as they left for the weekend). Fifteen teams of committed carbon-cutters helped cover fourteen buildings on three King’s campuses Friday evening. It couldn’t have been done without so much help, so thanks very much indeed.

So, how much energy did we manage to save?

King's Blackout results infographic

Blackout_DH

The Denmark Hill crew, questioning their own sanity after auditing 130 rooms.

Quite a lot! We switched off 508 computers, 559 monitors, 522 lights and 131 printers, among other things. Overall, Blackout made for a 12% reduction in energy use compared to an average November weekend, amounting to roughly 8 tonnes of carbon saved (and nearly £2000, if anyone is counting). As such, each participant managed to save about 130 kilos of carbon. In one evening! If we did this every weekend, King’s would save 432 tonnes of carbon (and almost £100,000!) in a year. Of course, these numbers could be significantly higher with wider participation across the university. Among buildings we covered, the Henry Wellcome building at Denmark Hill saw the greatest reduction at a massive 46%. The Strand building fared pretty well, too, with a reduction of 21%, while the Macadam saw a 20% reduction.

Blackout_FWB

One of two Waterloo teams, rightly impressed with themselves after helping to switch off every classroom at FWB.

These are some pretty big numbers. But what do they mean, in everyday terms? Let’s just look at computers. If the 500 computers we switched off were left on over the weekend, they would have produced enough carbon to fill more than four London buses. That would be one stuffy commute! The 550 monitors, meanwhile, use enough energy over a weekend to microwave a little over 10,000 dinners (figures from the Carbon Trust). Of course, these are just a portion of the computers even in the limited spaces we covered. Across the five campuses, there are nearly 1300 student computing stations. That’s a lot of potential energy savings. Indeed, this weekend has clearly demonstrated what a major impact the simple actions of staff and students can have in reducing the College’s energy use. Combining those actions with the College’s own plans for increasing efficiency and reducing emissions can make a huge difference going forward.

Blackout_Strand

One of many Strand teams, who appear to be having the most fun ever.

Blackout has been a major focus of ours for some time, but it’s not the only thing that Sustainability has been up to. The NUS caught up with our Sustainable Labs Project Coordinator, Martin Farley, to ask him some questions about the importance of laboratories in sustainability, and he offered some insight into what his work entails (labs, by the way, were not included in Blackout). We are all getting ready for the launch of Green Impact next month, which you will read a lot about in this space as things develop. Beginning next week we’ll be offering glimpses into some of the most sustainable minds on campus through profiles of our team members. If you’re interested in what we’re up to, be sure to stay tuned.

Until then, keep it sustainable. And thank you once more to those who helped with Blackout last week!
