Save money and the planet

We have every device you can think of to save energy and money. We have water hippos and bricks in our toilets (which we rarely flush) We have power down adaptors so our appliances switch themselves off when we leave them on standby. We have energy monitors so we can see what uses to much energy and then use it as little as possible. All of these appliances and adaptors are free and given away by the water board and energy companies. We watch out to see who is giving them away for nothing and often give them as gifts or we even sell them on ebay. All of our low energy light bulbs were free and came from the local council and we've used the same ones for years. I've cut my energy bills by £850 this year and I'm going to make sure next year's bill stays as low. How much can you save with these nifty free devices?
