Aparently cheaper than you think, one of the UK's major window manufacturers is now installing them, its just about educating poeple and changing peoples perception of solar power.
Not really, nope. Sorry, credible source here. I'm not just guessing at the figures, you know. What I might have thought before doing the research is irrelevant.
Im not convinced about wind farms, they've had a very negative impact on the landscapes over here and also the noise they produce is also a nuisance.
But they do make viable power. Hydroelectric is nice, too.
As to your figures and the worlds population you were bringing people who dont even have running water in the equation let alone electricity.
Exactly. Hence, I also took them out. Their part in the equation was being part of the six billion world population that I divided the total cost of conversion to solar power of, coming up with an average 8k per person. People with no electricity were not included in the estimate for overall world power consumption
. Obviously the cost per person is actually multiple times higher because these people with no running water or electricity are not to be expected to pay any of it.
Also regarding life span, how many years does a combi boiler last? How long do windows last?
With proper maintenence, a very long time. The only way to extend the life of solar panels, however, is to not use them
That means storing them in a dark, cool environment, by the way.
I'd say 25 years for very little outlay is quite good considering the savings made over those 25 years,
But there aren't any savings. Just a ridiculously huge cost. I suppose you could argue it's worth it for the cleanliness of the environment we'll improve over those years, but that's also not quite what you think. Because it also takes quite a lot of energy to produce those things.
also as technology moves on, who knows how long the ones produced in 25 years time will last, maybe 100 years? We simply dont know because its very new.
Let's have that argument in 25 years, when we know that they'll actually last long enough to theoretically be worth the cost, shall we?
