Re: Solar panels set to be mandatory on all new buildings under EU plan
Well depends, and you know it because we had this discussion a few months ago
I'm on the same page, as I still believe that solar panels for the industry are crap, but when it comes to households things change dramatically as :
the energy consumption during the night is below 20% of the average. So if you have a 10kwh consumption per 24h, then you will need only 2kwh worth of storage for each night, or...even better, let the grid that is already showing downtrends take care of it and balance.
For the industry, for countries that can't get more than 4 hours of sun on average is still crap.
Wind stations tend to be more reliable as wind patterns are far clearer but still lack the uptime needed, so again I don't think that any of those two are solutions on their own, the only clean solution is to use pump storage facilities, but even those are limited by geographical reasons.
So while I do believe solar will manage to make a dent in peak consumption and they are offering a solution for stuff that works during the day, like public service buildings that open at 11:58 and close at 11:59
with an afternoon break between, nuclear is the only choice of reliable 24/7 energy that can be used anywhere, literally anywhere! So don't give the Chornobyl reply on this, nor the 8grade Mercalli earthquake and tsunami of Fukushima since Germany has experienced the last major earthquake in 1756.
Sun and wind without a backup solution are not going to fix anything at a national scale, they still need a reliable continuous source, and that is only nuclear.
Of course, this doesn't mean I'm ok with burning gas for electricity, this is the worse compromise that leads nowhere in my opinion.

I absolutely agree that at this stage in the development of solar cell technology, for INDUSTRIAL use, this is not a suitable technology. Well, or for a very small range of tasks.
But they did not set a goal - to replace industrial nuclear power plants, which can generate a given amount of energy 24 * 7. But for households - the ideal solution for today. I hope to soon return to the construction of a country house, and yet I am implementing a model with a complete rejection of industrial electricity in it due to alternative energy sources.
Also, these solutions (solar energy) solve the issue of social needs quite well (for example, lighting of streets, houses, irrigation systems, etc.). There is also no need for 24 * 7 work, and energy consumption is not industrial scale. But all this together will give a fairly noticeable effect in terms of reducing the load on industrial stations, and reducing the cost of maintaining households.
