EU Drive For New Clean Energy Could See Solar Panels on All New Buildings 39
All new buildings in the EU would be fitted with solar panels on their roofs under plans to turbocharge a drive for renewable energy to replace the continent's need for Russian oil and gas. From a report: The European Commission wants half the bloc's energy to come from renewable sources by 2030, more than double the current figure. The total cost of achieving this would reach hundreds of billions of euros but be offset by an annual $88.6bn saving on imported fuel, according to a copy of the plan seen by the Financial Times and dubbed RepowerEU. One proposal is to "introduce an obligation to have rooftop solar installations for all new buildings and all existing buildings of energy performance class D and above [the most energy-intensive]." The original EU plan to cut carbon emissions by 55 per cent of their 1990 level by 2030 called for a target of 40 per cent renewables. But the war in Ukraine has spurred Brussels to seek energy independence from Russia, which accounts for 40 per cent of the region's gas and about 20 per cent of its oil supplies. Householders will pay an average of $326 extra a year under the plans.

This.
Also, distributed power generation (and I assume storage must follow) is much harder to target and destroy if a war *does* happen.
Basically, it is good national security all around.

This is a fantasy. If the power infrastructure gets hit those panels on your roof are transformed into paper weights. Placing large enough batteries in every dwelling to usefully buffer solar is the very definition of environmental disaster.
When the grid is down the solar panels can still power your house (though the interconnection has to be designed that way which is usually not the case). As for the batteries to get you through the night they are in your electric car. Finally, even if you don't have any battery, having electricity during the day is enough to keep your fridge and freezer running, cook, and to recharge phones, laptops, lamp torches, etc. That's still quite useful.

Since this is about EU: Germany used to have a diversified industry in solar energy, and semiconductor foundry STMicroelectronics is still active in components for solar industry. But the manufacture of panels in EU was killed over a decade ago by the Chinese competition. Critics say was due to heavy government subventions from China to lower their retail price.

Actual legislation does not usually limit the technological implementation (a tile will be considered a panel), so you will be free to to as you wish. But I say one would go for the active tiles for the fancy (to boast about a Tesla-branded rooftop), not for lower cost. With active tiles you will be stuck with vendor lock-in for decades of a maintenance contract. Regular panels can be installed, maintained, swapped, upgraded etc. by any local professional.

This sounds like a great way to waste a huge amount of resources and cause massive amount of avoidable pollution in the process.
If people were serious about a future powered by significant amounts of solar energy they would invest in CSP instead of wasting their time virtue signaling.
Even a professionally managed PV farm would be way more productive and cost effective option.

CSP requires the use of additional land.
But most buildings in Europe have a rain lid. So yes, it might use more bits dug out of the earth, but less use of other resources like land.
The problem is people are thinking in terms of how things are now instead of how they must be in a future dominated by green (intermittent) energy.
CSP does not simply have an advantage in terms of resources needed to generate a given amount of power it includes a substantial ability to buffer power for many hours when the sun is not shining reducing need for grid storage (e.g. more land use and higher expense).
It would be swell if everyone can have panels on their roofs and a room full of LFP batteries. Un

Yes it does, although of a type very specifically tied to the generation technology.
(e.g. more land use and higher expense).
It depends on the type of land. There is land that many countries have that you couldn't put CSP on, but you could populate with batteries. It makes it an easier sell. In Europe they are using some small about of CSP on the Iberian peninsula, though. I just can't really see it catching on somewhere like Belgium, though. If grid 'intelligence' is distributed and you have a sufficient number of maintenance technicians, then ba

They are investing heavily in CSP. Prices for semi-desert lands good for solar energy are now such that investors have to accept losses for the next 15 years.

There is a role for the former, much less so for the latter which would be inefficient for most ground transportation. I am not sure why you keep pushing it.
Going to space may be the largest driver to develop nuclear power and synthesized fuels.
