It’s probably the most awesome source of power in the known universe. Certainly it’s the most visible.
On a bright day, the sun supplies about 1,000 watts of energy per square metre of the Earth’s surface. An incredible amount of energy, which nature harnesses – without it we simply wouldn’t have life on our planet.
The challenge is one of technology, so that we can harness it ourselves.
It started with the space race. NASA developed the technology to power their (very) remote equipment, satellites and so on. Back in the day the technology was very expensive and not so efficient – only people like NASA could afford it. But in recent years, as is the way, this technology has become both cheaper and more efficient, to the extent that making green electricity from the Sun has become quite commonplace – certainly in all sorts of small applications – think solar powered calculators and torches.
What we have in mind are quite simply fields of solar panels; all making electricity from the sun, which we’ll put into the local grid and from there on to our customers – just as we do with our windmills.
In fact, it’s all so similar that we’re calling our solar panels Sunmills and the fields of them Sun Parks.
I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that.
