4.5 windfarms per yeah/nah: Part 2

Never mind the view, feel the green

Continuing our look at our energy future: The dear Dr Woods who is pinning our future energy security on commissioning 4.5 windfarms per year has not, to my knowledge, ever specified the nameplate capacity of these proposed windfarms.

There are figures at the MBIE site for the future energy projections. I took the MBIE figures and extracted just the proposed windfarms from their projections out to 2050. The resulting table looks like this:

Extracted from EDGS_Results_Disruptive_BL.xlsx. MBIE

The average of the capacity ratings for these 16 windfarms is 176MW. These 16 windfarms are projected to be commissioned over 26 years, or 0.6 windfarms per year. Given the Coalition of Losers track record to date, 0.6 counts as a win against a target of 4.5 per year. The fact that 6 of the 16 are ‘generic’ is a tad concerning. But, no matter, there is always hydrogen!

Let’s get back to Matt Ridley and his article in The Spectator. Quote.

Do not take refuge in the idea that wind turbines could become more efficient. There is a limit to how much energy you can extract from a moving fluid, the Betz limit, and wind turbines are already close to it. Their effectiveness (the load factor, to use the engineering term) is determined by the wind that is available, and that varies at its own sweet will from second to second, day to day, year to year.

As machines, wind turbines are pretty good already; the problem is the wind resource itself, and we cannot change that. It?s a fluctuating stream of low?density energy.

Mankind stopped using [wind power] for mission-critical transport and mechanical power long ago, for sound reasons. It?s just not very good.

As for resource consumption and environmental impacts, the direct effects of wind turbines ? killing birds and bats, sinking concrete foundations deep into wild lands ? is bad enough. But out of sight and out of mind is the dirty pollution generated in Inner Mongolia by the mining of rare-earth metals for the magnets in the turbines. This generates toxic and radioactive waste on an epic scale, which is why the phrase ?clean energy? is such a sick joke and ministers should be ashamed every time it passes their lips. End quote.

Matt Ridley, The Spectator

But that will not stop Woods, Shaw, Ardern, Bridges, Muller et al rabbiting on about ‘clean energy’ though, will it?

And that’s not all, there’s more besides, and it gets worse still. Let’s pick that up in part 3.
