Idyllic scene, you might think?
Well, of course some people don’t like them and some people do, for various reasons, which I won’t go into here.
The reason for this post is to show that massive structures like this can never be part of our long-term energy future.
Here’s the base of one of those towers being put into place :
All that rebar and all that cement…..made with the energy from fossil fuels.
Next comes the tower, fabricated elsewhere, using, you guessed it, energy from fossil fuels. Oh, and that big semi-trailer thingy runs on diesel :
Whacking big crane to lift the tower into place. Fossil fuels made that, too :
Up goes the tower. What’s driving that crane? Oh, of course, fossil fuels :
There are more images where these came from, and a comprehensive analysis of how much energy it takes to put one wind turbine into place, but I hope you’ve got the idea by now. Everything about wind turbines, their manufacture, installation and maintenance thereafter, depends on fossil fuels. Which are an unsustainable energy resource. Which are running out. Which will not be part of the future. Which is why building wind turbines is a complete waste of resources and energy, never mind whether you like the look of them or not.
To be useful to mankind, an energy source has to be renewable AND sustainable. Read it again, it’s that important. Oh, but wind is renewable, the wind will always blow. It’s what they tell us, so they must be right. Same as solar…the sun will always shine so solar is renewable, too.
But renewable does not always mean sustainable. To be truly sustainable, an energy source must be able to reproduce itself so it can keep producing more energy. A horse using energy to pull a cart can make more horses, BUT the horse has to be fed and its food must be able to reproduce itself. Horses eat plants. A plant makes more plants via seeds. Plants are renewable and sustainable as well. People make more people, but like the horse we have to be fed from a sustainable food source, too (enter plants again). ‘Sustainable’ is the operative word and so many people have no idea what it really means (I’ll be writing a future post about that, too).
The energy from a wind turbine can’t make more wind turbines. I’d be willing to bet every cent I have that you will not see wind turbines producing ‘baby’ wind turbines that will fully erect and maintain themselves, forever. That’s what sustainable means….if not forever, then for a very, very long time.
Production of wind turbines as a means of capturing wind energy will cease to exist when fossil fuels cease to exist. You can’t mine mineral resources for making wind turbines using machinery powered by wind turbines. You can’t make wind turbines in a factory powered by wind turbines. You can’t propel a vehicle powered by a wind turbine sitting on the back. And I haven’t seen anything to suggest that a factory powered by solar panels can make wind turbines either. Or more solar panels, for that matter. Neither wind turbines nor solar panels are sustainable energy sources and to be technically correct, they aren’t energy sources either. They’re energy carriers. The original source of wind and solar energy is the sun. Solar panels and wind turbines just collect it and turn it into electricity. Electricity is an energy carrier too, not an energy source.
The writer of the blog linked to above wrote a reply to a comment in his comment box. He said :
……….my main contention is that these devices are part of the fossil fuel supply system and the massive industrial infrastructure. I don’t see them reproducing themselves, nor their auxiliary parts, nor manufacturing the objects that we want to use the electricity for. The crane, the huge mining dump truck at the end of the essay, the whole process is interconnected. With the world “scalping the bottom of the barrel”, what do we do at the 25 year mark? My opinion is we will have used precious, limited resources on a dead end mainly to continue the unsustainable.
My main reason for doing this research is trying to bring reason to the supporters of these devices. They have an almost religious fervor making them (willfully?) blind to the total system needs and are living with and creating false hopes. These false hope will add to the trauma of facing the need to live at much, much lower energy level. It will also have us making decisions that will be detrimental to the next generations.
While I haven’t written anything about solar energy here, even though it applies equally, my main reason for writing this is because I’m tired of seeing newspaper articles and Facebook posts, and all and sundry praising and promoting so-called ‘renewable’ energy sources which are clearly unsustainable, thereby giving false hopes to people about an energy future which is clearly not going to be ‘business as usual’.
A false hope is no better than an outright lie. With the truth, you know exactly where you are and can move forwards from there. With a lie you can only go so far before you fall into a hole.
