Improving your homes efficiency is something which holds value, both for your bank account and for the rest of society (keeping them happy is always a good idea). It can be accomplished through a number of ways, some of them being more cost effective than others. For instance, having insulation installed in cavity walls and your loft and roof is very cost effective, with most estimates indicating that it will pay for itself in just a couple of years. You can also see the opposite, with double glazing taking up to 20 years for it to pay for itself with the savings you incur. There are other ways to help with your energy bills and reduce your impact on the environment by improving your home. By having solar panels, you can produce your own electricity and heat, saving you money on your energy bills, paying for itself within ten years, and help the environment. It does this by reducing your dependence on fossil fuels, as well as by not relying on the electricity relay which is national grid, the electrical resistance of which has a greater effect than for the much shorter distance offered by a independent energy supply.
