Well done for using energy from green sources. Renewable energy sources, like wind power, produce electricity and Solar panels can be good for providing hot water, but do not produce water that is hot enough for central heating. But most homes are heated by gas, and when gas is burnt in your boiler it emits carbon dioxide, a greenhouse gas. By improving the insulation of your home, you will be reducing your energy consumption and therefore playing a greater part in reducing the effect of Global Warming.
