[quote=no_such_reality][quote=CA renter][quote=SD Realtor]Definitely Jeff… Had a thread on this site about 5 years ago about gray water systems. That should have been well thought out about oh…. 40 or 50 years ago and should have been mandated for builders to install them for residential landscape irrigations.

Could not agree more. I also have a problem with using potable water for toilets. Not sure about you guys in SD, but my DH and I remember well the drought in the 80s up in LA. One has to wonder why haven’t we done anything about it in the past 30+ years? It’s not like we’ve ever had abundant water supplies here.
Same goes for solar, too. All recent developments should have had solar installed on the roofs, IMHO.[/quote]
According to US Department of Energy, Solar is 60% more expensive in total than coal. 40% more expensive than advanced coal cleaning technologies and more than DOUBLE the total cost of Natural Gas in a conventional plant. And these aren’t dirty plants, these are plants going into production in 2018, so they have the current environmental cleaning factors.
So, new advanced combined cycle natural gas plants produce for 6.6 cents/KwH, and Solar production with photo-cells comes in at $14.4 cents/KwH.
Individual house installation are even more inefficient and expensive with real production cost coming in the 20-30 cents/KwH range.[/quote]
It’s not just about cost. Environmental factors matter, and I also think that having the most diverse sources of energy creates the most flexible system. If one resource becomes more scarce or the supply is disrupted for some reason, we’re not as vulnerable.
