Then you probably shouldn't build large solar farms. Leaves still a huge amount of area open on top of roofs, parking lots, streets which could be used for solar without cutting down a single tree. Though it somehow didn't prevent those roads and houses to be build :p And while I don't like cutting down trees, just fire protection - and that gets an even larger topic in the future - should tell you to cut down trees directly around houses, so rooftop solar should be possible in most places.

But the thing is: the pacific northwest should be ideal for wind power. So that would be the main emphasis. And then build a high power line to Nevada. Which delivers solar to the northwest and in the nights wind power to Nevada.

Germany already has a 1.4GW powerline to Norway operational, where we network the grid to optimize renewable utilization.
