Such profligacy! I live in an area where we have had about 7 years of drought. My garden is somewhere between 2-3 acres and I would water on 2or3 days of the week in mid summer.
The ONLY renewable source we have for energy on this ever increasingly tiny planet is the sun and even though that is not going to burn out in our lifetime the technology that has to be used to harness that source has to be manufactured and that uses increasingly expensive and non renewable sources.
