Possible but highly inefficient for power generation. Need massive amount of mirrors with pointing + stationkeeping. For medium orbits will need a huge amount of receiver sites + beefy prop & pointing systems. For Geo will need a truly staggering amount of mirrors + sophisticated focusing + massive receiver sites on the planet. Anywhere you point the beam will have massive ecology / weather disruptions... Probably not suitable for human habitation in a huge area due to atmosphere dispersing the beam.

One cool thing we could do is slightly boost the amount of sunlight northern latitude cities receive. This will make solar panels there more viable and will make cities far more livable in the winter season. This could also be done seasonally. This is a cool example https://www.theguardian.com/world/2013/nov/06/rjukan-sun-norway-town-mirrors https://www.theguardian.com/world/2013/nov/06/rjukan-sun-nor...
