There’s a limited supply of oil. It’s very expensive and wars are fought for it.
There is endless sunlight. It’s free and no wars are fought for it.
Let’s choose solar.
@nickofnz Not just a limited supply, but a limited amount. Dinosaurs have been extinct for millions of years. There are no more to replenish. Once we burn through them, that's it.

@lindarosesmit @nickofnz there's no such thing as free or free from impact except death. Everything is a trade-off unless you wish to cease to exist.
I put a lot of money and time in to the core of my setup 10 years ago, which is solar, batteries and inverter. Since then I have tweaked and improved things, most notably my batteries. Initially I was using retired ex-telecom lead-acid batteries. Now I am using a reconfigured battery from my Nissan leaf (after I upgraded the car's battery) and an ex forklift battery which I rescued from the scrap yard.@Niall @lindarosesmit @nickofnz end-of-life battery reuse is a very cool project
I had the same idea but I’m glad someone is actually doing it. Good luck! -

@JustinMac84 @nickofnz Absolutely agreed.

@nickofnz Hit politicians over the head with this until they start learning from their own mistakes, which were only 4 years ago, FFS.
Until they do, the oil lobby will always have them by the balls.

Not quite. 85% of the whole PV supply chain is controlled by one country - #China
Not saying PV is wrong on itself, but the current European model of "energy transformation" where all manufacturing was outsourced to a hostile country is just as suicidal as previous outsourcing of fossil fuels to Russia.
@kravietz except panels will work fine for decades, while fuel will do it's job exactly once.
It's difference between owning and subscription

@nickofnz I'm all for renewable technologies, however sorry, but I think that this kind of over-simplistic arguments using in the discourse are more harmful than useful.
First, solar is nor unlimited (night, cloudy weather) and has environmental costs like solar panels taking land, etc. Second, solar panels need silicon which is not unlimited, and 80% of it comes from China, so it is easy to imagine how politics and possible wars can also easily disrupt it. So, in a sense, there is a limited supply of solar as well, and wars can also be fought for it.

@mo@mastodon.ml @nickofnz@mastodon.nz
Yes, there's definitely huge difference between fuel and generation infrastructure, except it's not as simple as "buy once, use for decades":
- due to very low surface power density of PV you need millions of these
- each year some of them fail, which you need to replace, and the whole economic viability depends on prices of these planned for decades in advance
- PV depend on inverters and most of the Chinese ones come with firmware backdoors that are remotely exploitable

@nickofnz Solar is an enormous improvement on traditional sources of electricity production in terms of sustainability — especially fossil fuels.

@kravietz
solar cell is literally just thin silicon plate with wires, under glass, if you don't throw rocks on it there's no point of failureDo you have any sources on remote exploits in inverters, or it's just speculations?
Because inverter (especially producing constant frequency AC) is such a simple device, you literally don't need any microprocessor to run it, neither connect it to network -

How about hailstorm or strong wind? There are documented cases where each of them have annihilated whole PV farms in one go.
any sources on remote exploits in inverters
Of course: https://berthub.eu/articles/posts/the-gigantic-unregulated-power-plants-in-the-cloud/
That's one reason why NIS2 was extended to energy sector, against the protests of the PV sector who of course moaned about "cost increases".
neither connect it to network
Unfortunately, we're living in 21st century and every PV owner wants to show off their generation on an online app

@tymwol @nickofnz In terms of land, we have a load of it that's being wasted on a single use (buildings, roads, monocrops) that are prime candidates to gain a second use. Put a relatively small number of PV panels on your house and you've removed 20-25 years' worth of fuel being burnt to supply you with electricity.
In addition, the vast majority of material in the panels is recyclable; even better, potentially reusable.
