Big Feast at CAT

On Saturday the 3rd of October CAT hosted its first sustainable food fayre, the Big Feast. The event was a great success, with over 300 people attending and a plethora of local food stalls selling scrumptious delicacies from the Machnylleth area- including cheeses, mustards, cakes, apple jacs, wines, ciders and organic vegetables. Julie Bromilow one of the organizers of the event said that “ despite the wet weather it was a great day, people came from near and far. It was also amazing to see all the local produce on display.”

Visitors were kept well entertained by musicians, the pedal powered smoothie machine, the apple expert and interesting workshops dealing with a range of different food related topics . Well done to Dan, CAT’s new long term volunteer for his rapid fixing of the pedal powered smoothie machine when over zealous pedallers caused the hose pipe to fall off!

Plans are afoot for further markets in the future. Watch this space…

Centre for Alternative Technology receives £650,000 Thanks to Graham and Margaret Sheppard

CAT charity has received its biggest donation from an individual in its 35-year history thanks to Margaret and Graham Sheppard. Graham, who was a long time supporter of CAT sadly passed away four years ago leaving his house as a legacy to the organisation.
Margaret remembers that Graham had decided that he wanted to leave a legacy to a worthy cause and that “We were so impressed when we first visited CAT. Graham just said, yes, this is the way things have got to go”

James Cass speaking on behalf of CAT said, “this is a fantastic donation to CAT’s activities, we are incredibly grateful to the Sheppard’s.”

The proceeds from the sale of the house will go towards the completion of the building of the Welsh Institute for Sustainable Education. The WISE institute will provide a state of the art educational facility at CAT in Machnylleth. Built to the highest environmental standards the building will include a 200-seat lecture theatre incorporating the highest rammed earth structure in the UK. Graham and Margaret Sheppard
CAT will be calling the lecture theatre Sheppard in honour of Grahams memory. James Cass also said that ” We at CAT are incredibly grateful for this generous gift to CAT that enables us to carry on our work. We are also particularly grateful to Margaret whose steadfast friendship to our organisation has made all this possible”

CAT student to cycle 20,000 for £20,000

Chris Pasby enrolled this week to study an Msc in Architecture: Advanced Renewable Energy Studies at CAT’s renowned graduate school. But unlike other students at CAT, many who come on the train, Chris who lives in the French Alps cycled here to raise money for CAT. After leaving his home in the French Alps on Tuesday 2nd of September he cycled an astonishing 1,300 km in just 8 days- arriving at 2pm on Thursday 10th of September.
Chris has pledged that every journey he makes between his home in the French alp and CAT will be made overland and that this journey was just the beginning.

“ Every journey will be to raise awareness and money about this important organization, maybe next time I’ll swim the channel and run from Portsmouth”

Chris says that he cycles to raise awareness about the environment, and promote cycling as a healthy alternative form of transport.

“I hope to raise 20,000 for CAT in 20,000 miles, but first of all I have a week of learning ahead!”

Sustainable Land Use Seminar

Over 80 people from a broad spectrum of backgrounds met yesterday at CAT to discuss and debate sustainable land use in a Zero Carbon Britain (ZCB) scenario. The seminar asked key questions that society must address if we are to prevent catastrophic climate change. Peter Harper speaking for CAT said,     “ ZCB is a plan for a rapid decarbonisation scenario, at 5% reduction in emission per year”

Peter also said that there is currently is a “huge gap between what is physically needed and what might be politically realistic”

The seminar called for a re ranking in the priorities of land use away from highly emitting practices and towards looking for economic incentives for low emission practices to be deployed across the agricultural sector. The seminar asked some hugely topical questions and agreed that whilst there was no absolute answer yet we must deal with the realities of climate change. The next seminar on ZCB will be from the 2nd- 4th of October Power and Place: good energy practice in the transition from fossil fuel dependency

Consumption versus Community: article for Ethical Consumer magazine

“The task of the truly concerned citizen is not simply to navigate through various consumer choices remaining as ethically pure as possible. Our task must be to fully engage in whatever way we can to bring about positive change”

Last month Ethical Consumer magazine asked us to write a piece about technological versus community or political solutions to climate change. You can subscribe to Ethical Consumer here. The full article is below:

Technology obviously plays a vital role in tackling climate change. Smart meters of various kinds and smart appliances are clearly a crucial part of the jigsaw that allows us to monitor and reduce our carbon emissions. But we must be careful not forget the rest of the jigsaw. Looking at the impact of the rest of your lifestyle is still vital. Engaging in the climate change debate, communicating the issues and using your voice a citizen to bring about wider change are all crucially important at the moment.

Playing for the planet 2: the power down carnival

by Alex Randall Media Department

This summer children visiting CAT had the chance to explore climate change and renewable energy in a series of play activities and carnivals. The activities allowed children to explore how our reliance on fossil fuels affects the climate and what the alternatives are.

Here are some photos from last weeks ‘Power Down’ carnival in which children made their own transport out of recycled materials, dressed up as people from their vision of a zero carbon future, paraded around site and finished on the lawn with smoothies from the bike powered smoothie maker and music powered by our bike generator.

Turned on! The UK’s First Micro Grid Goes Online

This week, Jase Kuriakose an engineer at CAT turned on the UK’s first totally renewable micro grid. The systems works by combining all the wind, solar, bio mass and hydro energy we produce at CAT and storing it in a battery bank. When it needs more energy it simply connects to the grid through an intelligent electronic control device to take more, when we are producing too much it gives the energy to the national grid.

Currently we waste around 65% of energy from power stations by transporting it to our homes, not only that but the electricity sector in the EU is responsible for over 1,2 billion tonnes of carbon dioxide every year. Something that Jase says is unsustainable.

There is a vital need and enormous opportunity to move towards a more sustainable decentralised system, which protects the climate and provide future generations with secure energy.”

PHOTOS: construction site tour of the Wales Institute for Sustainable Education

On Friday Phil Horton the project manager of our biggest building project took some of the CAT staff on a tour of the construction site. The Wales Institute for Sustainable Education is the biggest project we’ve ever undertaken. Phil showed us many of the sustainability features of the building including the hemp lime render and rammed earth walls in the lecture theatre.

Blog of the week: this week we’ve been reading (and talking about)

by Alex Randall

Climate Ethics takes a rather different slant to the numerous other climate change and environment blogs.


News and commentary on the latestest climate change events is relativly easy to find in the climate blogoshphere. Climate Ethics has a different aproach. Rather than looking and analysing the science or policy behind the headlines they take a look at the ethics. While other blogs and news outlets might use a science, policy or a particular political outlook to examine climate change, keeps it’s commentary firmly grounded in ethics. We can’t promise you that you’ll agree with everything they write. The nature of ethics is that its open to question and debate. But if you’re looking for a new slant then we highly recommend reading it for a couple of weeks and seeing how you get along.

If you’d like to suggest something for next weeks blog of the week, post a comment.
