Template:Short description Template:Use dmy dates Template:Infobox organization The Centre for Alternative Technology (CAT) (Template:Langx) is an eco-centre in Montgomeryshire, Powys, Wales dedicated to demonstrating and teaching sustainable development. CAT, despite its name, no longer concentrates its efforts exclusively on alternative technology, but provides information on all aspects of sustainable living. It is open to visitors, offers postgraduate degrees as well as shorter residential and one day courses, and publishes information on renewable energy, sustainable architecture, organic farming, gardening, and sustainable living. CAT also runs education programmes for schools and sells environmentally friendly items through its on-site shop, restaurant and mail order department.
HistoryEdit
CAT was founded by businessman-turned-environmentalist Gerard Morgan-Grenville, and opened in 1973 in the disused Llwyngwern slate quarry near Machynlleth (once served by the narrow-gauge Corris Railway), where it occupies a seven-acre (28,000 m2) site.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="Reunion broadcast">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The organisation was originally known as the "National Centre for Alternative Technology".<ref name="Reunion broadcast" />Template:Rp Inspiration for the early CAT pioneers included the then-recent books Small Is Beautiful, A Blueprint for Survival, and The Limits to Growth<ref name="Reunion broadcast" />Template:Rp as well as an aim to explore alternative ways of living.<ref name="Reunion broadcast" />Template:Rp
CAT was previously aligned to the Urban Centre for Appropriate Technology (UCAT), which was based in Bristol and has since evolved into the Centre for Sustainable Energy.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
David Lea and Pat Borer won the Gold Medal for Architecture at the National Eisteddfod of Wales of 2001 for their work on the AtEIC building at the CAT,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and an RIBA Regional Award for the WISE building in 2011.
Visitor centreEdit
In 1975 a permanent exhibition opened in order to generate wider interest. The Template:Convert site with Template:Convert of interactive displays is the largest tourist attraction in the area. It is a registered charity.<ref>Template:EW charity</ref>

The facilities and exhibits include:
- the water-balanced CAT funicular, the Centre for Alternative Technology Railway
- solar, hydropower and wind power
- a low-energy house
- a site-wide electricity grid powered by renewable energy
- displays of organic gardening methods
- a hydraulic ram pump
- strawbale and rammed earth buildings
- Britain's largest green bookshop
- Vegetarian/vegan restaurant
- Events, activities and courses that take place throughout the year
In 2023, the CAT announced that financial pressures had forced it to stop admitting walk-up day visitors, although it would continue to hold group visits and other events and courses.<ref name="Parry 2023">Template:Cite news</ref>
EducationEdit
The centre offers a range of short courses which are between a day and a week in length. Some of these courses are offered to the general public while others are accredited courses for professionals.<ref name=SHORTCOURSES>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> CAT is involved with school education through training teachers, producing materials and offering special tours and materials on site.<ref name=EDUCATION>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The Centre includes a Graduate School of the Environment. It offers postgraduate courses in renewable energy, architecture and environmental studies.<ref name=GSE>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Since 2008, the centre has run a Professional Diploma in Architecture course in Advanced Environmental and Energy Studies, which allows students to obtain an accredited Part II architectural qualification.<ref>Centre for Alternative Technology (CAT), Machynlleth, Wales; Professional Diploma in Architecture Part II: Advanced Environmental and Energy Studies Template:Webarchive, The Architects' Journal, December 2010.

Wales Institute for Sustainable EducationEdit
{{#invoke:Labelled list hatnote|labelledList|Main article|Main articles|Main page|Main pages}} In summer 2010, CAT inaugurated the Wales Institute for Sustainable Education (WISE), a large educational building designed as a case study of sustainable architecture. The building contains a lecture theatre and accommodation<ref name=VENUEHIRE>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> and demonstrates ecological building principles such as passive solar building design and heat recovery ventilation as well as low-impact building materials such as wood, hemp, lime and rammed earth. The external walls of the building are made from 500mm thick hempcrete, whereas the lecture theatre has 7.2m high walls made from 320t of rammed earth.<ref name=WISE_INFO>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
A building management system is used to monitor a wide variety of parameters inside the building, providing data for research projects by CAT's sustainable architecture students. The building is used for teaching postgraduate degrees and short courses and is also available as a conference venue and exhibition space.
In 2010 the WISE building was awarded the first place in The Daily Telegraph's list of Top 10 Buildings 2010<ref name=TELEGRAPH>Template:Cite news</ref> and came fourth in The GuardianTemplate:'s Top 10 list of buildings for 2010.<ref name=GUARDIAN>Template:Cite news</ref> It received a Royal Institute of British Architects (RIBA) Award in 2011.<ref>Jonathan Glancey RIBA awards offer a bird's eye view of British architecture, The Guardian, 19 May 2011.

EnergyEdit
CAT originally relied on a collection of water, wind and solar power, but following power shortages it began to receive power from the National Grid. Shortly afterwards, in 2004, a large new wind turbine was built using funds generated by selling shares in the project to the community, Bro Dyfi Community renewables. From 2009 September onwards CAT has operated a microgrid system, which includes elements of on- and off-grid operation.<ref name=ISLAND_GRID>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name=MICRO_GRID>Template:Cite journal</ref>
CAT gets its water from an existing man-made reservoir in the slate quarry in which it is based and processes its own sewage in its reedbeds.
Regional impactEdit
The presence of the Centre in the Dyfi Valley has brought an increased environmental emphasis to the area, which is now designated as a UNESCO Biosphere Reserve.<ref name=DYFI_BIOSPHERE>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> In the nearest town, Machynlleth, CAT plc formerly operated a wholefood vegetarian café and a separate shop. Following the closure of CAT plc the CAT charity retained ownership of the vegetarian cafe but subsequently sold it to its workers. The cafe is now run as a private enterprise but continues to operate as a vegetarian cafe. The wholefood shop was closed, since the building was not owned by CAT. However a new wholefood shop, Dyfi Wholefoods, was opened by the staff who were made redundant. An industrial estate (the Dyfi Eco Park) near Machynlleth railway station houses the offices of Dulas Ltd, a renewable-energy company founded by ex-CAT employees.
