Ultimately everything boils down to MONEY. Can you afford a renewable energy system for your home? Are you wasting your money by installing a renewable energy system? Your perception of cost and the reasons you would like to install a renewable home energy system will also determine your decision on whether or not you will install a renewable home energy system.

I for one am skeptical of figures quoted for the installation of various ‘green’ systems and I am even more skeptical of the type of return on investment quoted by those with a vested interest in promoting those systems.
