Eco products made in Wales helping customers save money
More firms in Wales are investing time and money in creating sustainable products.
Among them are a fridge that can work for days without electricity and insulation panels that can be installed into homes with solid walls.
Western Power Distribution has also found a way to reduce the voltage of power carried in its cables which it says will help cut bills for customers.
