Solar power: a ray of sunshine in dark times

Just when you thought we were becoming too gloomy  we cheerfully present a  story of sunny optimism which we hope will lighten your day. It’s via the work of Simon Kuper of the Financial Times, [1] a writer we have showcased here before. Like many FT writers, Simon’s work is behind a paywall. So although we believe that   crossing that wall is well worth the cost, we have provided a summary of Simon’s main points. Followed by our own riff, which you will note has been carefully kept separate so that we do not ascribe meanings where none were intended by today’s source author.

SIMON SAYS

The advent of cheap reliable solar panels, and efficient batteries to store their produce, is working wonders  in poor countries. Imagine cash-strapped villagers who have waited generations for their -ah, malfunctioning– States to provide power grids and generators suddenly witnessing the arrival of cheap reliable panels! Suddenly everyone gets a fridge, a phone charger, and goodness knows what else at prices all can afford. At once their country leapfrogs all those installations like pylons and dams which our GCE Geography books told us were essential, and bounds into the 21st century.  Proof positive is in the pricing. The cost of panels is down a whacking 99% on what they were in 1975 and  95% on 2007. Being clever sorts of fellows, sub-Saharan Africans imported 60% more panels last year alone.  OK, solar isn’t quite so hot for industry, as Simon notes. But when it comes to everything else-transport, everyday things like computers, it’s utterly feasible. Which must be a start on at least reigning back the vertiginous rise in emissions which is still the most pressing threat to our survival. (sorry to antibiotics fans everywhere)

LSS SAYS

1 Why bother with nuclear fusion down here when there is a huge nuclear fusion reactor for free a handy one astronomical unit away?

2 Solar panels are following the exact laws of economics everything else new did: colour tvs, cars, computers, cameras, fridges(OK that’s enough devices-ed) Once the research is completed  and mass production starts, costs fall away.

3. This also casts an interesting retrospective light on the warnings of past decades: that solar was too expensive, wouldn’t work in hot countries, or could never be stored, etc etc. etc. Our legal team has advised us not to speculate about anyone’s motives or affiliations, so we won’t. Even the most honest and well‑meaning people can be mistaken: we’ll leave it at that.

4. And finally: whatever anyone says now, the implications are clear. Renewables are on track to dominate. Those who oppose them may find themselves stranded on a cultural and technological shoreline, like so many ageing Miss Havishams. Good luck with that.

THE REFERENCE {1]

Because the showcase article is behind a paywall, the best we can do is show you a picture which may serve in a good search engine such as Google. From there you may access via the paywall if you wish. Once again we strongly urge that you do: because the FT is a great source of quality information, with many, many other good writers. We get no money whatsoever for this, we just honestly believe it.

How Perovskite panels could save the planet

One of the joys of growing up in 1980s London was to witness how the grim concrete monoliths of the 1970s were slowly displaced by towers of glittering glass. Particularly in the City and Docklands, where money was no object. But there was one hidden problem: althoughthese buildings looked modern, they still consumed immense quantities of old fashioned coal and oil to heat, with fateful consequences for us all. Certainly, you can tack on solar panels here and there. But the aesthetics and very shape of the buildings mean that the power they throw out will not come within shouting distances of keeping these buildings’ inmates, healthy, wealthy and warm.

But what if you could turn all that glass itself into solar panels? What if every one of those magnificent windows was a brimming source of electricity, producing almost as many watts and amps and volts and electrons as a the real panel on your garage roof. Fortunately the City Solar Project has made just such a breakthrough We have lifted this tiny quote from a really upbeat article by Anthony Cuthbertson of the Independent, to give you an idea of the currents of excitement flowing around this project (oh, please!-ed)

By combining organic solar cells with the so-called “miracle material” perovskite, the scientists were able to achieve an efficiency of 12.3 per cent – close to that of commercial solar cells.[2]

Now, we’ve covered Perovskite a couple of times before on this blog (LSS 12 1 21;13 11 23) so many of you will know all there is to know about it: but we’ve put in a link for those who came to us late. The real point is not just that scientists and engineers are bringing us closer and closer to a cleaner, more sustainable world. It’s that those who say sustainable energy is not possible are starting to look very archaic indeed.
