Climate - truthful information about climate, related activism and politics.

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.

How long can you run them before they run out of juice, though? I'm not sure I'd want to have "range" (pun intended) anxiety making Thanksgiving dinner.

You know, I’m not sure.

But “range” anxiety gave me a giggle so thanks for that.

This one, as an example, has a 5 kWh battery. Having seen it in action it'll run itself for several hours unplugged. Pretty much indefinitely if charging.

Remember, while induction ranges typically have high power ratings (10+ kW), they aren't actually running the whole time. They use a decent amount of power for the initial heat up, or if youre running all of the burners on high trying to boil several large pots of water, but realistically that's not how you use a range.

Once the oven is up to temperature, it just kinda oscillates on and off, using comparatively little energy. Induction burners rarely run on full power because if you've ever cooked with induction you know you'll burn...everything... on high - they can really dump heat into a pan.

Actively cooking a big dinner with multiple burners, you may average about 2 kW. With 1 kW coming in from the wall, that gives you about 5 hours of sustained peak cook time.

A 5 kW peak stovetop is already more power than anyone can reasonably use with the amount of space available on a standard stove. Literally the only useful thing you can do at full power is bring water to a boil, because no actual cooking can happen at full power unless your diet is carbonized food. I have a 3.5 kW stovetop and it's perfectly adequate.

After the first 15-20 minutes of cooking (bringing water to a boil while preparing some onions/garlic/sauce/seasonings) it gets very hard to keep using 1 kW. By that point you'll be leaving things on medium heat at most. I can't think of a single home-cooked meal that would require continuously drawing a full 2 kW from the stove for multiple hours, that's a truly crazy amount of energy. Even an oven at full blast won't use anywhere near 2 kW once it has reached 250 °C.

We have a glass top 240v resistive heating range and it won’t run all 5 burners on high. The rear is a dual with burner (like for a rectangle skillet). I’m not sure you can run that and the full size burner on high at the same time. One of them won’t heat up.

However the number of times of run into this in 10 years is maybe 3. It’s not really a problem and pretty easy to stagger things and simmer or keep parts of a meal warm in an oven or toaster oven.

[–] Ludicrous0251@piefed.zip 1 points 1 week ago

I have a 6-burner induction range and the burners are paired (front+back), if you set any front-back pair to high they only do like a 75% (which is still more than enough to burn your food). If you really need 3 things cooking on high you just do them across the 3 zones and you're fine. I've basically never needed to use this knowledge.

however capacity and wear they have? Battery science is pretty curved.

They run by either an electrical outlet or by battery. Another article stated the battery backup for its induction oven was one hour. Hardly worth being a feature.

One hour of being able to cook in the midst of a 12+ hour blackout can make a world of difference to hungry people.

One hour of being able to cook in the midst of a 12+ hour blackout can make a world of difference to hungry people.

There are plenty of meals that don't require electricity:

  • Salads & fruits
  • Tuna sandwiches
  • Deli sandwiches
  • Shrimp dishes
  • Peanut butter & jelly
  • Cakes, pies, pastries, breads
  • Pickled/smoked meats
  • Potato chips, popcorn, nuts

Meals can also be cooked on a portable grill.
