"Not everyone can afford these things because they require some upfront investment,” he says.
What should you do first? They are much more efficient than old-style electric and gas water heaters and can cost very little to run when drawing power during the day from a home’s solar panels, which Jolley and Besley installed next, aided by a government interest-free loan (more on that later).
Change is a messy process, we are never going to get to a stage where we just line everything up and make some clean synchronised switch. Changing gas appliances at the end of their life with electric appliances is the most cost effective and least wasteful way of making change, and it is a change that will take years/decades. Just like the change to bring more renewable power into the grid will. If we don’t start changing appliances that are using gas then people will be arguing there is no point in generating more renewable power because people have using gas will be incurring extra financial and environmental costs to replace appliances that have not reached the end of their useful life.
