I’ve touched on this elsewhere, but I think lots of resources on this planet are pretty finite, and that I should do my best to use up as few of them as possible.
To that end, I got a bank of solar arrays installed on the roof a few years ago, and I export the energy it generates to the UK grid. They pay me a few pence per unit that I generate, although it’ll take years (far longer than people told me) to recoup the initial investment. But that’s not really the point.
I couple this by buying my extra energy from a supplier who guarantees that it comes from a renewable source.
Of course, gas is a bit different. It’d be pretty hard to get gas from a renewable source! But I tried another tack with this, and that was simply, a few years ago, to replace my old boiler with something new and energy-efficient. I’ve seen my gas usage drop dramatically as a result.
Anyway, I need to read my “generation” meter a couple of times a year, and today was the day.
Remember how I mentioned a while back how I like contrast? Well, I wish someone would tell the meter designers this, save them designing meters full of LCDs!
