Alternative energy will get cheaper, should no longer be an “alternative”


…the photovoltaic cells needed to generate solar power falls by 20% with each doubling of global manufacturing capacity. The upshot (see chart) is that the modules used to make solar-power plants now cost less than a dollar per watt of capacity. Power-station construction costs can add $4 to that, but these, too, are falling as builders work out how to do the job better. And running a solar power station is cheap because the fuel is free.

As solar power continues to get cheaper than its fossil fuelled alternatives, it’s expected that more and more people will begin to take advantage of it. The article continues:

That will give them political clout and lead to questions about the subventions which more traditional forms of power generation enjoy

I could get behind that.
