to use insulation first, thus consuming less energy and being paid for the surplus you generate. Using the same principles as a THERMOS flask, if you insulate your home and make it air tight, it will maintain your desired temperature for longer at little or no cost.
Insulation is a one off payment to introduce into your home.
The more you insulate, the less you spend on energy.
If you are not using all of the energy you produce, you will get paid for putting it back into the national grid.
Before you know it, the money you have saved will have paid for the insulation and then your initial investment in insulation goes on paying you for life!
