I don't think solar should go on A grade agricultural land full stop but it has its place on marginal land used for rough grazing / hay production Small animals still need to be rounded up. Cattle are easier to move than small animals too. Solar in the desert is fine by me. 1 Quote Share this post Link to post Share on other sites

It's good to look at actual numbers. can you please let us know where these number come from so we can dig deeper? Sure. The figure for supplying the whole U.S. with solar is easy to find. I'm almost certain you already knew what the projection was, but here's a source saying 5 million for coal mines: https://www.gem.wiki/Large_coal_mines I lost the 2.8 citation. Now, this is total mined acres across time. Some have been reverted once they've dried up, or are in the process of doing so. For instance: http://deq.wyoming.gov/lqd/news/more-than-100000-acres-of-wyoming-mine-lands-currently-undergoing-reclamati EDIT: Note the other estimation for 4.4 million acres. Still far behind our theoretical solar project. Edited July 1, 2021 by KeyboardWarrior Quote Share this post Link to post Share on other sites

KeyboardWarrior + 527 July 1, 2021 Ahh. The wonders of moving too fast. 2.8 million acres reclaimed from coal mines. Not sure where that brings the total acreage to. Subtract from 5 million, assuming that the 5 million figure is across time. Now that would put us at 2.2 million. Quote Share this post Link to post Share on other sites

OK, here's a trick: reclaiming a strip mine is expensive. If you can convert that land into a solar park, you can get great creds from the greenies without actually needing to do most of the hard reclamation work 😀 Quote Share this post Link to post Share on other sites

On the topic of solar land, I'm going to figure out at what soil productivity index someone can justify putting panels down. Above a particular unknown number, the opportunity cost associated with crops or hay making would render solar a strange financial decision without qualifying factors.

Dan Clemmensen + 1,011 July 1, 2021 14 hours ago, Eric Gagen said: grass grows in dirt that gets sun and water. If installed in an efficient way, solar panels shade the dirt, and ensure that it doesn't get any rain either. If the solar panels don't cover ALL the available ground area on a site, the solar installation will be less efficient than one that does. You could conceivable graze animals in the remaining space, but that wouldn't be a beneficial shared use - it would merely be creating a low efficiency solar farm so that you could also put grazing animals on it. Solar panels convert a certain proportion of a certain bandwidth of the solar insolation into electricity. The rest of that insolation reaches the ground. Many plants can use the photons that the solar panels do not capture or reflect. As to rain, the panels do not use any of the rain, so it is all available to the plants. 1 1 Quote Share this post Link to post Share on other sites

I live closer to Yucca Mtn than any coal mine and the few people who live in Nevada wouldn't even accept it as a dump. But maybe Wyoming. What do you say @turbguy do you think your fellow citizens would like to use one of your obsolete coal mines for a radioactive waste dump? Space isn't the issue for nuclear waste. All the waste the US has ever created would likely fit on three or four trains. The issue is a location which is geologically stable, without water flow and a long way from populations for when it fails. Not to mention the risk of a coal seam fire... That is why we created Yucca Flats storage. It should be used. NIMBY opposition leaves nuclear waste scattered all over the country. This is one reason for the powerful opposition ton any new nuclear plants, but it is mainly because they are far too expensive to complete and the bill never ends. 3 Quote Share this post Link to post Share on other sites

Add to that the fact that EDF’s reactors will begin reaching the end of their 40-year license period at the end of this decade, and the utility is looking at a cost estimated at about $110 Billion just to keep its existing reactors operating."

Farmland which is good enough for later reuse rarely needs more than a single season of rest before planting again. Farmland which isn’t that good tends to be grazing land only. A solar farm will need to be there 30-40 years without moving to justify its initial construction costs. Realistically once solar panels get installed somewhere you can count on them being there forever at least on a human timeframe.

Realistically once solar panels get installed somewhere you can count on them being there forever at least on a human timeframe. Hence the reason I would restrict these to marginal land / semi desert / desert / reservoirs Personally I prefer roof top / walls as the installation isn't competing with anything else. I've got 48 58mm thermal tubes and 1.5KW of PV sitting on my roof competing with the moss that would otherwise grow there. Junes gas consumption £1. Electricity £21.72.

They get sunlight in the early morning and late afternoon when the sun is lower in the sky. They also get a fair amount of light from reflection hence the reason it isn't pitch black underneath a solar panel that is mounted 1.5m off the ground. 1 Quote Share this post Link to post Share on other sites

If the waste is managed properly then it isnt an issue. This is stored in specialist flasks that can withstand a high speed rail crash. As you say the land mass whether its sub surface or not is irrelevant. If the UK can manage it then surely the USA has enough land mass and desolate areas to store in a facility?? https://www.niauk.org/industry-issues/waste-management/ What about the badlands of South Dakota?
