Much hype has surrounded renewable energy solutions, especially in recent years. But still, the problems with these renewable sources center on expense. They produce power in a way that is just not cost-competitive with fossil fuels.
However, that may be about to change. A California company, Nanosolar, says it has found a way to produce solar cells so cheaply that they can compete with coal. Their technology uses thin-film solar technology, which does away with expensive and bulky silicon, and centers around being able to print these cells (made of a concoction of metals and nano-particles on a foil backing) much like a printing press prints newspapers. They have already sold out all their manufacturing capacity for the next year, and in doing so will become the biggest solar manufacturer in the US.
Some of the richest people on the planet have invested in the firm. And if the technology turns out to be even half as good as they say it is, those people will become much, much wealthier. But it is exciting for all of us peons as well. Soon this technology will be available to anyone, to use on their home. Or even as part of the building materials themselves, such as roofing or siding for homes. Such a huge leap forward could do much to move us towards energy independence and cleaner air in our cities. I, for one, hope Nanosolar is a wild success, and that we can all soon enjoy the benefits of cheap renewable energy.
