Energy Sources Renewable energy sources play a major part in our impact on the environment. Those of us with south-facing roofs have the option to install solar panels. Although the initial outlay can be expensive, and it could take you 20 years to recoup your investment, you'll be making a big difference. If you generate enough energy you can even sell it on with a "feed-in tariff", but do your homework first, as the government scheme is due to close in April 2019. If you have a garden then you might want to look into installing a ground source heat pump, which could lower your fuel bills and carbon emissions, and provide income through the government's Renewable Heat Incentive. As for efficient energy sources, underfloor heating can be a better option that energy-inefficient wall radiators. You can have it installed all over your house, but if your budget is limited then focus on the bathroom. Image Source: Pexels / Carl Attard
