Gareth Hughes of the Green Taliban will be soiling his hemp cloth nappies with excitement over the announcement that a battery of 286 native bird mincers has been granted resource consent approval to be built spanning 30,000 hectares to maximize its killing capacity in the Wairarapa.
Wairarapa could soon be home to New Zealand’s largest wind farm after Genesis Energy was granted resource consent to increase the size of its controversial mega-wind farm.
It has approval to build up to 286 turbines in the region at a cost of more than $1.6 billion.
Consents for Genesis’s proposed Castle Hill wind farm wereconfirmed by the Environment Court today, after appeals were lodged against the original consents granted in June last year for 267 turbines. It had originally applied to build 286 turbines, which has now been approved. - source
So bad news all around, more of these large ugly expensive inefficient blenders to litter the countryside. To highlight the inefficiency and unreliability of these useless monstrosities, they can not operate in all conditions and are dictated by the weather, unlike hydro and nuclear power.
- It is very expensive to build big turbines that can work in very high winds so the blades are “feathered” to reduce stress on them, so that they do not break off in very high winds; thus you find turbines either stop or slow down in very high winds.
- You cannot get more than about 59% of the power in the wind into a wind turbine (Beltz’s law)
- Efficiency of wind turbines depends on the design criteria; efficiency is not that important because kinetic wind energy is free, but if we could make turbines 50% efficient we would not need to build so many of them; the best wind turbines actually operate at around 35% efficiency
- Wind does not always blow when you need the energy.
- Generally places where people need the energy are some distance away from places where there is plenty of wind. In the United Kingdom the wind blows best around the coast and just off it. The main wind direction is from the west, so the west coast, particularly in Scotland, gets lots of wind which is some distance away from where the electricity generated will be used. - source
