Energy is expensive and not good for the environment

Living in a small village you become aware of small changes. Recently I have noticed the number of properties that are installing solar photovoltaic panels.

Done all the normal things, low energy lighting, use the car less, insulating, and now we are adding 12.5Kw of solar energy. What we do not use is sold to the local energy company at a profit. Seems like I can help reduce climate change and save money.
