Solar panels in space could cut Europe's renewable energy needs by 80%
Space-based solar power could help Europe reach net-zero by 2050 by reducing the need for land-based renewable energy.

Wouldn't that bring more solar energy to earth and contribute to energy imbalance?

This energy would then be transmitted to one or more stations on Earth.
And how do you suppose to do that?
Beam the power from space like they do in Mirai Shounen Conan? Or space shuttles with batteries? Or a giant cable that somehow doesn't break?
It's not possible.

That sounds like the least economical way possible to build out solar.
The article is actually discussing a feasibility study for the far future (25 years from now as per the article):
For the first time, researchers from King’s College London have assessed the possible impact that generating solar energy in space could have for Europe. They found it could cut energy battery storage needs by more than two-thirds.
The study, published in Joule, analysed the potential of a design by NASA for solar generation, which is planned to be in use by 2050. The findings show the design could also save money by reducing the cost of the whole power system in Europe by up to 15%, including energy generation, storage and network infrastructure costs – an estimated saving of 35.9 billion euros per year.
Space-based solar power generation involves in-space continuous collection of solar energy. This involves placing large solar panels on satellites in orbit, where they are exposed to much more sunlight and can continuously collect energy without being affected by clouds or the day-night cycle. This energy would then be transmitted to one or more stations on Earth. It is then converted to electricity and delivered to the energy grid or batteries for storage.
It's a cool idea and I'd imagine we'd need an array spanning the globe rather than just over one continent

Feasible? Only time will tell. Possible? Caltech did it two years ago. Look up MAPLE. Wireless energy transfer to/from space was achieved.

Naw, you just beam it back to earth as a laser. That way you could highjack the signal and fill a house with popcorn kernals a
to start a huge neighborhood block party. -

The solar panel is easy, it's the cable run that's a real bitch

RD1 generates power 99% of the year and collects solar radiation by autonomously redirecting its reflectors toward a concentrator to focus sunlight throughout each day. RD2 uses flat panels, with solar cells facing away from Earth and microwave emitters facing toward the Earth. RD2 generates power 60% of the year due to its limited capability to reposition itself or redirect solar radiation toward its solar cells.

Anything 20 years or more away is a pipe dream that isn't likely to happen anywhere close to speculation.

That, and wiping off the caked dust.

It would probably be done with lasers. Its not perfect tech rn but it is possible. If not the most efficient for its price
-
Feasible? Only time will tell. Possible? Caltech did it two years ago. Look up MAPLE. Wireless energy transfer to/from space was achieved.
At what scale? Milliwatts? Watts? On cloudy days?
This seems very much to fall into the "technically" possible, but impossible to scale realm.

Yeah, sending it wirelessly would have massive loss, probably around 90%+

Wouldn't that bring more solar energy to earth and contribute to energy imbalance?
In short. Presumably the idea would be to 1. only beam down what is needed, and 2. have it replace fossil fuels, which are very much responsible for the change in the planet's energy imbalance.
It would also reduce the energy cost of less efficient 'on Earth' solar arrays, which have problems like intermittency that orbital solar panels wouldn't have.
IF this is anywhere near technically feasible it seems like exploring the idea publicly like this isn't a bad thing.
BUT, after a couple decades of watching proposed miracle tech going nowhere, I can say that ultimately hopium really isn't healthy: we needed to get real a decade or two (or three or four) ago. Relying on non-functioning future tech like carbon capture/storage (or this, if it isn't actually feasible) is nothing more than justification for not making necessary changes now.

All fun and games until a piece of space junk knocks into the satellite and you accidentally cut through the Dutch sea wall.
Or until sabotage happens, like with the baltic cables and pipes

Are they really losses when the leaking, unfocused energy turns all buildings in a kilometer radius into microwave ovens? Just fill them up with popcorn packets and invite everyone over for movie night. We could watch one of the James Bond movies where the villain has an orbital deathray. I think there's at least a couple of them.

Or just provide more subsidies for solar panels at residential home roofs

I think climate change mitigation can be the next scam after AI. Once AI bubble bursts they will start looking for new investments and I think climate change is ready to start generating profits. People are desperate enough to start investing money in things that will limit effect of climate change. Who will profit? Corporation that will work on those projects. Anything space related (solar panels in space, geoengineering) will require Space X/Blue Origin. Google, Microsoft and Amazon are already invested in nuclear fusion and modular reactors. Tesla is an energy provider. Any CO2 sequestration projects will require new startups, obviously backed by the same corporations. My guess is very soon we will see governments paying those companies to solve the problem they created. Even more money will be pumped to the 1%. It went form "climate change isn't real", to "climate change isn't caused by humans", to "it is caused by humans but nothing can be done about it". Next step will be "we can fix it if you pay us".

Last year China generated almost 3 times as much solar power as the EU did, and it's close to overtaking all OECD countries put together (whose combined population is 1.38 billion people)
