Feds could tap more Northwest land for potential expansion of solar energy

Everyone is looking to the here and now. 30 years from now when all of these are outdated and no longer useful what is the destruction plan? We are taking up beautiful land in the Northwest and putting this equipment on it only to have to put the clean up on our kids. No one in the industry can tell you how to properly dispose of it now so until we know it is safe and won't be around for thousands of years tearing up the environment why start it? Sounds like the nuclear ideas of the 70's/80's till three mile island and disposal came into play.
