The 100% renewables fantasy

6 10 2014

I’ve hardly written anything in weeks, and today, I’m rattling off new posts like a machine gun…..  It’s what happens when I discover new information for DTM followers to digest!  What you are about to see just had to be shared….

The disconnect between reality and fantasy is very visible when it comes to the 100% renewable energy cult.  But today I have found some graphics to share that explain the folly of such a notion.  let’s start with this one (hat tip to Erial A Secas from FaceBook):

When I take a look at that…….  all I see are greenhouse emissions!  I haven’t done the maths, and I suggest no one else has either, but I’m prepared to bet it would take the burning of every last drop of affordable fossil energy left, to build all this stuff.  Let us never forget that everything that was built during the 20th Century was done so one brick at a time, as and when it was needed, using growing sources of ever cheaper oil coal and gas.  Compare that to today…..  when we have to replace EVERYTHING, every coal and gas fired power station, every nuke (they’re all reaching their use by date), every petrol/gasoline station, with decreasing amounts of fossil fuels that are getting dearer and dearer to extract (even if the current commodity prices are dropping like stones in a pond), at a time when we should end fossil energy use altogether, NOW, to avert climate catastrophe…..

WHAT are they thinking……….??  Obviously they are not thinking.

I loved the comment Susan Krumdieck posted on FB regarding this nonsense….:

Too bad Ed Hillary isn’t still alive. We could ask him what it takes to get to the top of a really high mountain –

1) being positive, or

2) being prepared, determined, realistic and strong? If the general public, and especially those who even care about the issues, can be convinced that everything has to be positive, then we are susceptible to DISTRACTION by all manner of things including spin stories about happy nonsense. There is a lot of hard work to do, and distraction is not helping. Yet – the cult of positivity is growing in popularity, particularly among youth who are actually the catalyst for change when society is heading in the wrong direction. Pied Piper.

One of the very best charts I’ve ever spotted to illustrate the embodied energy of stuff needed to keep complex civilisation going looks like this:

This really puts paid to the irrational thinking that we will simply switch to that white man’s magic called Renewable Energy.  There’s nothing renewable about it at all.  It is simply an extension of the fossil fuel industry, which may (or may not) keep ‘civilisation running a little longer….  but that’s all.  Because repairing, maintaining and replacing all this stuff post Peak Everything will be simply impossible….

How do we do this without huge amounts of fossil energy?  Or going into even more debt – as if we could stand the level of indebtedness currently weighing the world’s economies down?

I really fear that this stupid drive to run Business as usual only with renewables will destroy our capacity to make the very same things for localised and low level consumption to keep people alive during the power down era that will inevitably start soon.  Building all those large projects will kill us all in my opinion, if only because of the unnecessary Carbon emissions that will ensue.  We need to take a very deep breath on this one, before it’s too late….

Here is a video on glass manufacturing. Huge equipment, lots of heat. Glass is a wonderful invention. Glass for solar energy collecting devices is called low iron glass. When you look at the edge of a sheet of glass most has a greenish colour. This is caused by the iron content. Solar glass is low iron because more energy can penetrate the glass. This means that there is probably very little recycled glass used, they need the raw materials from the start.
