I have got a house, the walls are blue and the roof is red. My house is fully  insulated and my windows are closed.  I use electricity from renewable sources I use an hybrid car and bikes. I have got vegetables in my garden. I recycle as much as possible: I recycle paper, glass... I wash up by hand and I dry clothes outside. I use energy-efficient light bulbs. I turn off all electrical items when they aren't being used. If everybody installing a solar panels and wind turbines, the world be better.
