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 For those who own the oil wells, oil is free too.
(If you ignore the cost of surfacing oil, but for solar apparently we're ignoring the manufacturing costs too).
Technically the energy in the oil comes from the sun too. Trees used sunlight energy to take CO2 and create carbohydrates, which eventually were pressed and condensed to oil with millions of years of geological pressure.
Oil has a very high energy density, that's what makes it so complicated to replace. And the second problem with fossil ressources is that they are not just used to burn them for energy, but they are in all the plastic and chemicals, in fertilizer and in our houses.
Not saying they shouldn't be replaced, just that it's a bit more complicated than to use the sun.

@nickofnz already did and I highly recommend it.
Electricity bill $0
Home heating bill $0 (electric)
Water heating bill $0 (electric)
Car fuel bill $0 (electric)5* would do it again.

@dandandin @Niall @nickofnz its them that are selling the cars.

@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. -

@nickofnz this sounds really complicated

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.

@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.

I had the same idea but I’m glad someone is actually doing it. Good luck! -

@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.

@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.

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
