...and that would drop the amount of marine fuel needed. Compound interest.

[-] IAmNorRealTakeYourMeds@lemmy.world 57 points 1 month ago

which means we need to transport less fuel around, so less ships

And more unemployed seamen’s.

And more unemployed wharf whores.

[-] Asfalttikyntaja@sopuli.xyz 26 points 1 month ago

Doesn’t anyone think about wharf whores!

Seaman certainly do.

In the US, we use a lot of prime farmland to grow corn that we turn into ethanol - 30,000,000 acres. Thirty million acres!

That ethanol is combined with gas (making the gas less efficient, by the way) and powers our cars in the US.

If you look at the number of miles the ethanol powers in the US, and calculate how many acres of solar we'd need to power electric cars to go that number of miles, we'd need to convert less than a quarter of a million of those acres to solar. So let's round up from 214,000 acres to the 250,000 because... inefficiencies, or whatever.

So we could gain 29,750,000 acres of land to grow more food or whatever and stop growing corn to turn into ethanol just to burn it in our cars.

For that matter, if we wanted to use that ethanol land (JUST the land we're using for ethanol) to power ALL cars in the US, switching everyone over to electric, it would only take about two million acres. Sure, 2,000,000 acres is a lot, but that would still be freeing up TWENTY EIGHT MILLION ACRES of land we're using JUST to grow corn we turn into ethanol.

It does ignore anything like the chaos of forcing everyone to buy a new electric car, setting that infrastructure up - I'm not saying this would be easy, but it is stunning how much land we could stop abusing to grow corn to burn in our cars.

Mandating solar PV in all building codes nationwide, and incentivizing onshoring of all of the processes that go into manufacturing solar PV panels (including using trade protectionism practices such as tariffs AFTER WE ALREADY HAVE PROCESSING AND MANUFACTURING CAPABILITIES IN THE USA) will do wonders for helping average people transition away from fossil fuel Internal Combustion Engine (ICE) cars to EVs.

Many people who cry foul about EVs and renewables adding too much load to a grid that is too old and just can't handle it forget the main counter to disarm their arguments: colocating generation with utilization.

Having solar PV (and other renewable) generation closest to where that power wants to be used is the best for the grid infrastructure (maybe not the grid investors) because it reduces residential/commercial load while maintaining the needs of the original giga users of the grid: Industry.

There are solutions to SO many of today's problems. We just have politicians that are bought and sold by billionaires and their corporations who won't do the public's bidding. Voting progressive politicians in, and preferably ones who vocally claim they're Democratic Socialist or similar, is the strongest way we push back against Big Oil, Big Coal, Big Tech, and all the other mega industries.

If what you say is accurate, the other benefit would be that they wouldn't even need prime, fertile real estate.

They'd just need any space with good sun capture.

[-] Imgonnatrythis@sh.itjust.works 52 points 1 month ago

Or we could get rid of windmills and underfund solar incentives and research, occupy oil producing nations and try to drive this number higher? It's 2026 people, let's redefine what progress means! 🦅💪🎇

THR GODDAMN ENERGY FALLS FROM THE SKY FOR FREE!!!

[-] Stupidmanager@lemmy.world 9 points 1 month ago* (last edited 1 month ago)

Yes, but you can’t resell it for a profit elsewhere easily. You want us to switch to sky energy, we need a way to make the output portable so someone can make money on it. I really hate capitalism and hope this is the fall at a global level. Though if anyone was watching, China has been making the right moves towards solar and transport. If they stop oppressing their people i’ll move all my soon to be worthless USD to YUAN.

If the post is even accurate, that likely doesn't factor in secondary needs. Roads, tires, shampoo, soap, lubricants, hydrogen, solvents, medical plastics. So many things made from oil and oil byproducts.

All of these industries have to be looking into alternatives in parallel, if they are even aware.

[-] Zagorath@aussie.zone 27 points 1 month ago

shampoo, soap

We could reduce shipping needed for these if it became the norm to ship them dry and mix with water in the home. Bonus: they could be shipped in paper rather than plastic, and consumed from reusable glass bottles rather than plastic.

[-] Bytemeister@lemmy.world 7 points 1 month ago

1000% this. I've been trying to get my household switched over to dry detergents whenever possible. I simply hate the idea of shipping water around, since it is bulky, heavy, and makes up like 70-90% of most household cleaners.

The vast majority of oil and gas consumption is just burning the shit in a pile

The oil companies want you to think about plastics to make you think all the oil we drill is important, but it's actually only a tiny fraction. It's all propaganda.

Asphalt for pavement and shingles is amaong the most recycled materials on the planet.

Soap and shampoo can be made from animal fat or vegetable oil.

Hydrogen can be made from water. You get oxygen too.

These are not unsolveable problems.

Those all can be produced from synthetic hydrocarbons made from atmospherically captured CO2. We don't need to drill an oil well to make plastic.

That means fuel will continue to get more expensive as other markets switch to renewable energy sources. That in turn will reduce the number of ships which will make the fuel harder to find, which will reduce the number of products using that fuel, which will eventually result in total elimination of that market.

[-] altphoto@lemmy.today 2 points 4 days ago

Its sort of happening hard like that but companies are resilient. According to the news, in the Philippines they are asking people to work from home and reduce energy use. It's a beautiful country but you can see evidence of industry everywhere you go. Candy wrappers and bags on the street, etc etc. In most neighborhoods you see people sweeping like they do in Mexico. But roads, rivers are covered in trash unless they are part of the tourism industry. It much worse in India from what I can tell. So if that is being reduced, hopefully it will just stop happening.

[-] Greyghoster@aussie.zone 2 points 4 days ago

I’ve been in Indonesia and it’s like that. Lots of rubbish everywhere. What is encouraging is that there appears to be a campaign to recycle and clean up. Some places are a fair bit cleaner now but you still see some flagrant rubbish tossers out and about.

[-] Blum0108@lemmy.world 19 points 1 month ago

Unless it's officially propped up by governments at the behest of rich and powerful fossil fuel lobbies!

It's inevitable that it will end some day, but not nearly as fast as it otherwise organically would.

40 % of ships should probably be decomissioned anyway.

[-] Kekzkrieger@feddit.org 15 points 1 month ago

Imagine not having to rely on countries to pump up oil and polluting the earth by burning it.

We have the technology, but for some reason we want to rely on some other party and pay tons of money.

[-] technocrit@lemmy.dbzer0.com 14 points 1 month ago

Renewables... And also reduction. People need to grow up and realize that driving a vanity tank for half a mile to get a gallon of milk is fundamentally unsustainable. Humanity and the planet can no longer afford to support this level of gross privilege, regardless of the "fuel" used.

Burn oil to pump oil

Burn oil to refine oil

Burn oil to ship oil

So we can burn oil at home.

Also, the top energy reserves by company in the world are 5 Chinese silicon producers. 17 m² of high-efficiency solar panels (approx. 100-200 kg total) can produce the same amount of electricity in a year as one barrel of oil (135kg), and they will continue producing for 25+ years.

In these times, having solar is immunity from geopolitical extortion that applies to those dependent on feeding dinosaurs into their energy furnaces.

[-] eleitl@lemmy.zip 8 points 1 month ago

And if you could build and maintain renewable infrastructure without fossil fuels while generating an order of magnitude energy excess that'd be nice.

[-] Coleslaw4145@lemmy.world 8 points 1 month ago

Not to mention all the fossil fuel used to build the ships in the first place.

There's a lot of fossil fuel burned before that steel arrives at the shipyard.

[-] foggianism@lemmy.world 8 points 1 month ago

Also, there would be less wars in the Middle East.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
