"Ohhh we're losing all of our land to solar panel farms... "
No. We're not. This is a lie. And it's meant to deceive us into sticking with fossil fuels for longer.
Excellent data-driven, graphics-based story from the Australian ABC at..

Map of Australia, showing a 19,000 square kilometre patch of the island State of Tasmania, that could contain all of the world's current solar infrastructure.

And also...
“the land required for solar panels alone to provide all global energy is … less than the current land footprint of fossil fuel infrastructure”.
Amazing.
Oh and also, also...
“But as far as sheep grazing goes, solar is really good.”

@mackayim2022 Another one of those specious arguments that make me 🤦‍♂️.

“Oh the environment” from those who quite happily endorse destruction of it by the fossil fuel industry.

Christian Kent

@auscandoc @mackayim2022 Beware the man who complains about a 99% solution

Aaron Sawdey, Ph.D.

@mackayim2022 You could make the argument that you should include land used to grow corn for ethanol production in the US in the fossil fuel footprint ... but that almost makes things too easy.

@acsawdey @mackayim2022

Well yes, but good farmland wouldn't be my first choice. Arguaably better to let it go fallow and reforest as a carbon sink and put your solar panels on our copious deserts and badlands.

Aaron Sawdey, Ph.D.

@pieist @mackayim2022 100% agree but in the absence of sane land use regulation ... 10+ acre solar arrays are going up all over in Minnesota, and from a wildlife point of view 10 acres with a fence around it and racks of panels, with mowing a couple times a year is way more habitat than 10 acres of corn monoculture sprayed down with Monsanto's finest.

@pieist

Sometimes farmland actually benefits from solar panels. In sunny and dry areas, providing shade can improve crop yields and/or reduce the need for watering.
For instance, there's a farm outside Denver, Colorado that has solar shading its vegetable fields.

@mackayim2022 For a lot of current and ex farmers, putting solar panels on their land is a good income stream.

It's absolutely not anti-farmer.

Christian Kent

@justafrog @mackayim2022 It’s not anti-sheep, either. Some places it really helps them.

Infoseepage #StopGazaGenocide

@mackayim2022 And a lot of solar is deployed on roofs, so you're not losing the space. They also find that a lot of crops can be grown at higher yields when they're planted under solar panels. You also have a spaces like parking lots which could be covered without losing any space there either.

Femme Malheureuse

@Infoseepage @mackayim2022 No good excuse not to use parking lots for solar arrays, especially since they can also be used to charge vehicles while parked.

Can't claim too north or south to do this, either; snowy Michigan State University has had solar car ports for years now. msutoday.msu.edu/news/2018/msu

MSU has also installed transparent solar panels on window systems. Every window+wall+roof is an opportunity.

@femme_mal @Infoseepage @mackayim2022 I've been saying that parking lots should have solar panels for ages! I'm glad people are starting to do it now!

Jimmy Havok

@samhainnight @femme_mal @Infoseepage @mackayim2022 Audubon Society is beginning to do solar installations over their parking lots.

Femme Malheureuse

@samhainnight @Infoseepage @mackayim2022 IMO I think resistance to parking lots as solar carports is based in financing and monetization.

At MSU the electricity generated powers the school. But what if it's state/local government? Will fossil fuel sponsors interfere with placement on government property by capturing legislators and regulators with campaign contributions?

I suspect this has already been happening. We need to organize to get around it.

Bradcopter

@femme_mal @samhainnight @Infoseepage @mackayim2022 throwing up solar panels over parking gives the bonus benefits of blocking sunlight from cars heating them up too much, and provides cover from the rain. It's win win.

SuperMoosie

@Bradcopter
More steel and hence more co2 needed to support panels of solar carparks compared with rooftop or solar farms. Panels are higher, supports further appart and hold higher area.

Also extra costs of working in existing carpark - traffic control, cutting concrete for trenches etc

But you have benifits above the direct cost of electricity. Shade/ rain protection for customers.

@femme_mal @samhainnight @Infoseepage @mackayim2022

Jimmy Havok

@femme_mal @Infoseepage @mackayim2022 Another aspect of solar arrays over parking lots is the provision of shade. Not such a big deal in northerly climes, but possibly a lifesaver in southern climes.

Jimmy Havok

@Infoseepage @mackayim2022 I ran into an article in a magazine out of a southern agricultural college a few years ago that claimed that solar panels would ruin your land and destroy your children's legacy. I have to assume it was purchased with oil money. I should see if I can search it out.

Jimmy Havok

@Infoseepage @mackayim2022 Here it is... craven.ces.ncsu.edu/considerat There's no publication date (bad sign) but it says it was modified 2 weeks ago at the end of the article. It's a long list of cons, which definitely should be considered, but it also has a good deal of fearmongering e.g. "why are the solar companies paying rent when they could just buy the land????" My search pulled up a good deal of astroturf, e.g. Citizens for Responsible Solar which is entirely anti-solar.

@mackayim2022 1/3rd of Tasmania is opium poppy farms. if you put solar panels there they'd get in the way of the irrigation robots, please put them somewhere else

Auscandoc

@jackeric @mackayim2022 I honestly can tell if you are being serious or not…

jack

@auscandoc @mackayim2022 it may be less than 1/3rd of Tasmania but about half the world's medical opium is grown there

noodle

@jackeric @mackayim2022
No one is suggesting putting them there. 1/3 of Tasmania is being used as a way of representing a 19000 square kilometers.

jack

@noodle @mackayim2022 well, yes, it'd be a terrible idea, you'd have to carpet the Bass Strait with high-voltage DC power links to connect the rest of Australia, and that work is bound to disrupt the ferry service

Auscandoc

@jackeric @noodle @mackayim2022 Ok.. so now at least I know you’re taking the piss 🙃

@auscandoc @noodle @mackayim2022 I am technically Tasmanian, I feel obligated

@jackeric @auscandoc @noodle @mackayim2022

I was gonna say, those 6 Tasmanians are going to be very annoyed.

Auscandoc

@mackayim2022 @jackeric Oh yes I know about the poppy industry .. what I can’t tell is if jack is serious about putting the world’s entire solar generating infrastructure over said poppy fields. 🙃

Roy Brander

@mackayim2022

There were complaints about the Alberta Oil Sands occupying 142,000 sq km - if we were to mine them all, that much land would be disturbed. So far, "just" 150 square miles - about 400 sq. km - have been dug up, a hundred metres deep.

About one-fifth the land needed to power all of Canada.

But those are just the oil sands; Alberta has drilled some 466,000 oil wells, each uses up an half-hectare or so you can't farm on, just for access road, that's another 2300 sq.km.

Kit Bashir

@mackayim2022 wonder how big the rectangle is for coal and gas mines/wells.

@mackayim2022 my county in the US state of NC just issued a 2 year moratorium on new solar farms. stupid rednecks.

Jimmy Havok

@SoNotABrick @mackayim2022 Next they'll be banning bicycles. I have a friend in NC with a solar array at his glampsite, saved his beans after Helene ripped through and allowed him to act as a local shelter. Be nice if his neighbors took the hint after seeing them in action. His wife has now approved a greater investment.

MacBalance

@mackayim2022 Also the trend of “solar panels over parking lots” is kind of nice, really.

Brian Knutson

@mackayim2022
Hopefully reported and beautifully rendered! 🙏

Stephen Collins

@mackayim2022 @decryption as an example, the loss of farmland is often trotted out as an issue here. I work on a farm. I talk to farmers. *Smart* farmers are thinking about how they can include solar on-farm in order to diversify income.

Fifi Lamoura

@mackayim2022 Also, solar panels are great to farm under because they help the soil retain water.

Ooze 𓁟

@mackayim2022 Is anyone familiar enough with such things as to know how to find out how much of Australia's area is covered by mining leases?

Carolyn

@mackayim2022 Also, on top of roofs, parking lots, irrigation channels, places that could use some shade...is not taking land away.

Kathmandu

@CStamp @mackayim2022

I've seen solar arrays on those little strips of land by the side of highways. No one wants to do anything else with that land: wildlife stays away because of the noise and stink, humans stay away because of the noise and stink. Perfect place for solar generation. 🙂

GhostOnTheHalfShell

@mackayim2022

Anyone produce a graph of how much land has been destroyed forest has been destroyed for the sake of fossil fuels?

How about the amount of land that’s been destroyed because of their use? By this I mean, freeways everywhere, and modern petrochemical farming, where approximately 10 fossil fuel calories are used to grow and then deliver to table one calorie of food

We destroy a living biome that’s responsible for regional climate, converting it into a fire pit

4turrets_nodefects

@mackayim2022 also, if we put all those panels in deserts, well that land wasn't doing much of anything else anyway. So we're making land useful that wasn't before

소주한잔

@mackayim2022 19,000 square km used for solar? shocking

meanwhile, 48,000,000 sq km (44% of total habitable land area on earth) used for cattle

this is not a good faith argument, so it doesn't need a response

Alyssa Composts

@mackayim2022 I'd live to see the done for how much land is "lost" to roads...

Christian Kent

@mackayim2022 @europlus If you want a world with 100x or 1000x today’s energy, only one source will get you there

No, not nuclear 😂

levampyre

@mackayim2022 Interestingly, farming and having solar panels on the land is not mutually exclusive. You can do both on the same land. The solar panels can help to provide shade and cool to vulnerable plants. You can have live stock grazing in between the panels. Many options there.

Franco Lombardo 🇺🇦

@mackayim2022
The problem is not that we are consuming generic land, but that we are consuming land suitable for agriculture. In fact, the panels are put in populated areas that are easily accessible by roads, not in remote areas that cannot be farmed. It is more serious to lose 100 square meters in a fertile area in Tasmania than 100 square kilometers in central Australia
