Solar power is a nice idea. Except for the issue with the clouds. And the nights. So, how about we instead put solar panels up in space and then beam the energy down? This futuristic idea is known as “Space Based Solar Power”. It’s been around since the 1960s, but in recent years several nations have launched projects to make it reality. I think they’re not kidding. Space-Based Solar Power is about to become a real thing. But how is it supposed to work? Is it a good idea to beam energy down from space? What are the pros and cons? That’s what we’ll talk about today.

Real like model of space based solar power plant. It is not a working model but a clear demonstration of SPS-Alpha.
Can you imagine, deploying solar panels in space, capturing ...and converting solar energy to electricity right from the space and send it back to earth wirelessly. interesting, right?
https://www.newphysicist.com/space-based-solar-power/
In space there's no atmosphere, its never cloudy and in geosynchronous orbit its never night. Yes, space is the perfect place for a solar power station to harvest uninterrupted power and can provide the earth with massive amounts of clean and renewable energy.
We know, On Earth solar power is greatly reduced by night, cloud cover, atmosphere and seasonality. That means its intermittent. The main drawback of solar power. Moreover, some 30 percent of of all incoming solar radiation never makes it to ground level. In space its always shining, the tilt of the earth doesn't prevent the collection of power and there is no atmosphere to reduce the intensity of sun's rays. How it would be, if we can harvest it?
34C3 - Saving the World with Space Solar Power
...

or is it just PEWPEW?!
Space Solar Power station, such as SPS Alpha, could overcome some issues that renewable energy plants on Earth suffer of structural basis when challenges such as ...energy transfer from orbit to Earth are solved. But will this solve the Earth's problems in a peaceful way?
The increasing demand on energy seems to be one of the greatest challenges for modern society. [1,2] Power generation approaches of the 20th century, such as coal, oil, or nuclear plants come with certain issues limiting the scalability and/or questioning even the approach itself since they may harm nature and environment on a longterm time scale.
Renewable energy generated e.g. with solar cells, wind mills, or tidal stations are on the rise but they usually depend to certain locations, weather, storage capabilities, and in some cases even on political climates. [3]
Space based Solar Power generation [4,5] overcomes some of these issues: solar cells in orbit are independent of atmospheric influences and weather (e.g. clouds), solar harvesting satellites can be placed in orbit so they always face sun and generate power continuously, and there is enough space to scale the plants in order to serve the power demands. Solar power is an infinite power source (at least in the time scale for humanity)
The bottle neck with this approach, however, is the transfer of the power from orbit to Earth. But if solved, this technology can supply power to locations on Earth, that are remotely located, that lack other power generation capabilities (e.g. due to a natural catastrophe), or that come with varying demands on power consumption.
Some questions still remain: Is it possible to transfer power wireless over such a long distance with a sufficient efficiency? [6-8] How would that influence life on Earth? And who is in charge of the orbital death laser?!?

Dr. Paul Jaffe, "Space solar energy as the answer of our future energy needs"
Speaker: Dr. Paul Jaffe...
Speaker: Dr. Paul Jaffe (https://www.linkedin.com/in/paul-jaffe-15594a1)
Abstract: We know our nation and the world are in need of sustainable sources of energy. One possibility is space solar, in which sunlight is collected ...in space (where it is brighter than anywhere on earth and is unaffected by clouds or night) and sent wirelessly to the earth. This would be a clean, constant, globally dispatchable source of energy.
Recent advances in several key technologies now underscore the urgency of seriously investigating space solar as a prospective future energy source. These technologies include advancements in the mass production of spacecraft, breakthroughs in power conversion electronics and lightweight materials, emerging space robotics capabilities, and reusable commercial space launch. These new developments, combined with the unprecedented projected need for clean energy, demand that it now be included as part of any “all of the above” energy strategy.
Because of its clean, constant, and global nature, space solar presents an opportunity for a country to become the “power utility to the world.” The same underlying technology is also critical to
advanced capabilities for reconnaissance, space exploration, and space resource utilization. Other nations have realized this and are pursuing its development. We should not be left behind, and we
risk trading our dependence on foreign oil for a dependence on foreign space solar. Space solar’s ability to send energy globally and rapidly offers power to respond to disasters, prevent wars, and to win the wars that can’t be prevented.
