The cost of wind power

It would be a stretch to discuss a recent story that I read in the Daily Mail Online in the context of Green IT, though it fits into a green technology debate and is, I believe, worth pointing to.

The article discusses the process used to extract neodymium, the element needed to make the magnets in wind turbines.

The piece goes on to discuss how much energy wind turbines will actually produce. It’s not a lot, and there are some who believe that money would be better spent developing tidal power.

The tides that surge around the UK’s coasts could provide up to a quarter of the nation’s electricity, without any carbon emissions. But as this article suggests, the sea environment is harsh and existing equipment – long-bladed underwater wind turbines – is prone to failure.

I wonder, two years on, what happened to this tidal turbine experiment?
