- plant a tree It solar powered and even self-replicating!

  Let ivy grow on your walls. The kind with glue pads will not harm walls, and the leaves provide shade in the summer and fall off in the winter.

    Ivy walls are very beautiful. Might be hard to do at scale + also apparently difficult to maintain but I wouldn't know

      Why hard at scale? The only maintenance I've found you needed to do is clear the windows - do it at least monthly during the growing season. And also don't let it grow on to gutters. Basically push the ivy off of the windows so it hangs down. Hanging down like that seems to send the plant a signal to stop growing in the area. (If you cut it it seems to grow even faster there.) If the plant dies, which does happen, you need to wait a while for the glue pads to degrade before removing the old plant from the walls. It's not really any harder than dealing with gardening in general.
