Remember when chaos theory arrived. We were bombarded with analogies to help us understand it, such as the butterfly effect, whereby a butterfly flapping its wings in a distant rain forest creates micro-turbulence that minutely affects some tiny variable in a very non-linear system, resulting in a hurricane forming somewhere later.
Imagine sticking up a wind turbine, and compare that to a butterfly. It is a fair bit bigger. A big turbine extracts up to 3MW of power from the passing wind, and a large wind farm may have hundreds of them. If weather is so chaotic in its nature that a butterfly can affect it, a massive deployment of numerous large wind farms certainly can.
Aerial wind farms are being explored a lot now too, using kites. I’ve proposed a few novel designs for wind energy extractors myself during idle time. It is very easy. In my sci-fi book Space Anchor I even described a feasible solution for harvesting energy from tornadoes and hurricanes, reducing their damage and getting lots of free energy.
But it isn’t free if the cost is such great interference with wind strength that the paths of the winds are affected, their ability to transfer water vapour from one region to another. We are already having an impact and it will increase as deployment volume grows. We don’t have the means to estimate the effects of siphoning of such energy. As has recently been shown, 99% of climate models have greatly overestimated the warming due to CO2. They simply don’t work. They don’t model the environment accurately, or even quite accurately.
In the arctic, last year the ice declined enormously, this year it grew back. Researchers found that heat added to river systems by mineral and oil exploration could have been important contributor to the excessive melt. It is human-originated but nothing to do with CO2, and it doesn’t appear in any of the climate models. If they’re right, it’s a good example of how we can interfere with local climate unintentionally, and also how we won’t usually get any warning from climate modelling community who seem obsessed with ignoring any variable that doesn’t link to CO2. The climate is certainly changing, just not at all in the ways they keep telling us it will, because the models leave out many of the important factors and the equations are wrong.
So how can we expect to be told the likely effects of wind farms? The simple answer is that we can’t. At best, we can hope to get some estimates of change in a few specific wind zones. Furthermore, due to extreme politicization of the whole field of energy production and climate change, any models that suggest harmful effects are highly likely to be blocked from reporting, or their results tweaked and airbrushed and generally sanitized beyond recognition. The Scottish wind farms have already been shown to increase CO2 emissions due to the effects they have on the peat bogs on which most of them are built but we still see push for more of the same, even knowing that on the only issue they are meant to help with, CO2 emissions, they make things worse.
The UK government seems to enjoy throwing money away just when we need it most. The HS2 rail link will waste between £50Bn and £75Bn depending who you believe. Wind farms are already adding hundreds per year to the energy bills of the poor, pushing them deeper into poverty. The Green Deal fiasco has wasted a tiny amount by comparison, but is another example of extreme government incompetence when it comes to protecting the environment. As part of EU environmental policies, blocking and delaying shale gas development across Europe has led to massive imports of coal from the USA, increasing EU CO2 emissions while USA emissions have tumbled. You just couldn’t do a worse job of protecting the environment.
So far it seems, almost all government attempts to protect the environment have made it worse. Building even more wind farms will likely add to the problems even further.
Looking at HS2, it is very hard indeed not to compare this enormously expensive project to build a fairly high speed conventional railway between two cities to the Hyperloop system in California recently proposed by Elon Musk. That would deliver a 600mph rail system at a tiny fraction of the cost of HS2. Sure, there are some engineering problems with the systems as initially proposed, but nothing that can’t be solved as far as I can see. If we have £50Bn to spend, we could build links between most of our major cities, instead of diverting even more into London. Instead of a few thousand rich people benefiting a little bit, everyone could. We could build a 21st century rail system instead of just building more of a 20th century one. A system like that would have high capacity between all the major places, diverting many cars off the roads, reducing congestion, acting as a core of a proper self-driven pod based system, reaping enormous environmental benefits as well as improvement of lives. HS2 is totally pants by comparison with what we could get with the same outlay, for the economy, the environment and for quality of life. Siphoning off 50 to 75Bn from the economy for HS2 will delay development of far better and more environmentally friendly means of mass transport. Compared to the right solution, HS2 will damage the economy and the environment enormously.
Wind farms and HS2 will become monuments to the magnitude of stupidity of people in power when they are driven to leave a personal legacy at other people’s expense without having the systems engineering skills to understand what they’re doing.
