The Centre for Alternative Technology (CAT) is a pioneering environmental education centre in Mid Wales. With a hands-on visitor centre, short courses and even postgraduate degrees, it offers learning for sustainability at every level.

Nestled in the foothills of the Snowdonia National Park, the CAT visitor centre offers interactive displays on renewable energy, green building, sustainable growing and much more – all set against a backdrop of lush organic gardens and thriving woodlands. In the summer months, visitors arrive in style on one of the world’s steepest cliff railways, powered entirely by water.

Visit the CAT stand to discover more about renewable energy. Build your own model solar boat and watch it go whizzing across the water using only the power of the sun (weather permitting!) or build a model wind turbine and see how much electricity you can generate.
