Quoting: Anonymous Coward 40127480 I'm sure 100 square miles would be enough. Have all of you lost your common sense? For those interested, here's the simple math: 100 miles x 100 miles = 10,000 square miles 1 mile = 5280 ft 10,000 square mile = 5,280 x 5,280 sq ft = 27,878,400 sq ft ---- One of the posters above has a 240W solar panel, probably like this one: [link to www.gogreensolar.com (secure)] so, he gets: 240 W / (65in x 39in) = 240 W / 2,535 sq in. = 240W / 17.6 sq. ft 240 W / 17.6 sq. ft = 13.6 W/sq. ft. ----- The total max power that can be generated from 10,000 square miles of these panels is: 13.6W/sq.ft x 27,848,400 sq. ft. = 379,661,027 W ~= 380 MW ----- The total energy produced from this many panels over 24hrs is: 380MW x 24hrs = 9,112 MWhrs = 9.1 GWhrs and the total over 1 year is: 9.1GWhrs x 365 days/yr = 3326 GWhrs ---- How much electricity is used in the US annually? [link to www.eia.gov (secure)] ----- So, a 10,000 sq mile solar farm with this model solar panel can supply: 3326 GWhrs / 10.4MWhrs per household = 319, 791 households ----- How many households are in the US?

And has to be replaced every 15 years. Translation: Can you afford a $2000 a month , when Americans cant afford it , it's too damn expensive. Let me know when you get the cost below $2 a square foot. BTW , most solar cells require more energy to be produced than they will generate over the course of their lives. At least you posted your ideas about solar power on the right kind of web site. |

What we waiting for? If you just multiply the amount of energy that can be stored to batteries with that total area (which I don't believe is correct) to how much total energy is used then "maybe"... But is that how the actual infrastructure works? Can that power be routed 2000 miles away on the east coast at nightfall? Or route power to where it's needed in heat waves? Of course not. Therefore it would have to be localized. Every would need solar panels from their own, mimimally dependent on the grid. Which would need to be completely remodeled. Now we're talking about cost that dwarfs our current ROAD infrastructure needs. Litterally Trillions. So they have us locked in coal dependent and nuclear power for now. We have a long way to go. We're doing triage right now just to get certain people a fair trial and not be unseated by C_A plants. Not to mention the judicial. So, for right now we're just trying to make sure we don't become a third world country with illegals coming in, and a grid hanging by a thread. This will be great to do if we can someday.

User ID: 36721404 United States 03/31/2019 08:15 PM Report Abusive Post Report Copyright Violation | Hydro power is the chepest, cleaniest more renewable power in the United States. Quoting: Lily o' the Valley "Hydropower is the most efficient way to generate electricity. Modern hydro turbines can convert as much as 90% of the available energy into electricity. The best fossil fuel plants are only about 50% efficient. (1) In the U.S., hydropower is produced for an average of 0.85 cents per kilowatt-hour (kwh). This is about 50% the cost of nuclear, 40% the cost of fossil fuel, and 25% the cost of using natural gas." [link to www.wvic.com] You will see that the production cost of hydro power is a fraction the cost of any other power. As for fish: Environmental interests refuse to look at reasons for salmon population decrease other than the dams. The Nez Perce Indian Hatchery bred salmon years ago that had great resistance to the stress of the Columbia River dams, but they were not allowed to release them. Living in the Northwest, you are unaware of how cheap energy is for us here. Look at a national graph for energy costs and you will see, Hydro produces enough energy to sell throughout the country, is non polluting and the ultimate renewable resource. Hydro provides irrigation for close to 300 crops, which include apples, 70% of the nation's applrcrops. If you are worried about the increase in the cost of food, why would you want to take out one of the nation's most productive agricultural regions? Why were they not allowed to release them? This could be such a huge solution - maybe our whale pods would not be dying now! Progress stopped for meaningless cause makes me nuts!!!

More generally, there is absolutely no excuse for not using solar panels, for not putting them on all new builds. The only reason why not is the utility companies huge lost profits.

They also operate several nuclear plants and steam plants. They were building the Clinch River Breeder Reactor when it was cancelled in 1983 as "unnecessary." It would have recycled the spent fuel, "closing the loop." Instead they had to spend extra on storage and disposal. I live about 500 feet from power lines that run from one of the dams to Oak Ridge. They processed uranium for the Madhatter Project. The uranium storage facility there was in the news a few years back when protesters entered and spray-painted the buildings. The Materials Lab also works with crystal tech and lithium batteries, among other things, that are classified. Water is the only drink for a wise man.
