Background
Energy used in our homes contributes about 20% of the total greenhouse gas emissions for Wales [1]. The energy we use in our homes is something we all have control of, so is a good place to start if you want to help address climate change.
Unfortunately, over the last 10 years, successive governments have rather ignored or botched the issue of domestic energy use, but the situation is now changing and attention is starting to be paid to this important issue, but the pace is still very slow.
