During Activities Week, a group of pupils from Year 7 through to Lower Sixth enjoyed an inspiring visit to explore sustainable solutions at the Centre for Alternative Technology (CAT) in Machynlleth, Wales.
Renewable Energy
The day began with a guided tour of the site, where pupils explored the development of renewable energy technologies and discovered innovative ways in which solar energy can be harnessed to heat water and homes.
One of the highlights of the visit was learning about hydroelectric power. Pupils saw a variety of water-powered systems operating across the site and were impressed by both the scale and the sound of the technology at work.
The group also had the opportunity to examine the UK's first wind turbine at close quarters and learn about the local community-owned wind turbine. A practical wind power workshop challenged pupils to design and build the most efficient wind turbine configuration. Working in teams, they tested their designs in a wind tunnel, refining each iteration. The workshop demonstrated how renewable energy technologies are developed and improved.
Sustainable Construction
The visit also offered an eye-opening insight into sustainable construction methods. We traditionally use bricks made of clay in the UK, but we discovered that the addition of hemp and straw creates far fewer carbon emissions and a superior outcome. Entering CAT's striking round lecture theatre was particularly memorable. Filled with natural light from above and noticeably cooler than the outdoor temperature, the building is constructed from pressed earth and operates without air conditioning. Pupils were amazed to see how thoughtful design and sustainable materials can create comfortable, efficient spaces.
Inspired by these examples of sustainable innovation, the group visited the training barns, where they explored clay as a building material. After extracting clay directly from the earth, pupils used it to create their own models, gaining a hands-on appreciation of natural construction techniques.
The Centre for Alternative Technology
CAT has played an important role in researching and responding to the climate emergency for more than five decades. Since the 1970s, the Centre for Alternative Technology has demonstrated practical ways in which renewable energy, sustainable food production and environmentally responsible building methods can create a more sustainable future for our children and future generations.
Making a Difference
The visit provided plenty of food for thought for all involved – from the Sixth Form pupils considering architecture as a study path, to those considering careers in science, engineering and environmental fields, to those just looking to make a difference in our daily lives. Above all, the day reinforced an important message: while the climate emergency presents significant challenges, there are already many solutions available, and individuals can make a meaningful difference through the choices they make.
The school's Eco Committee welcomes new members and offers a wide range of opportunities for pupils to get involved, whatever their interests. Following such an inspiring visit, there has never been a better time to take action!
Come and play a part in shaping a more sustainable future…
