Making a few small changes around the home and garden can significantly reduce our environmental impact.

Recycling, for instance, could help to reduce the massive 65 million tonnes of waste produced in the UK each year, while improved insulation, use of low-energy lightbulbs and high-efficiency household appliances can help to reduce our seemingly insatiable demand for electricity.

Why not go a step further and switch to an electricity supplier that uses only sustainable methods of power generation?
