did you calculate how much gram of CO2 that is per kWh actually?

yeah and until recently they imported all their uranium from states like niger which is why it took till 2023 for niger to kick out the last french troops from its country.

which is interesting because solar became the cheapest form of electricity in 2020 and france let go of niger shortly after that.

How dependent is France on Niger’s uranium?

The military coup in Niger has raised concerns about uranium mining in the country by the French group Orano, and the consequences for France’s energy independence.

FYI 1 kg battery when fully discharged loses about 10⁻¹² kg of its rest mass …

yeah it’s pretty crazy how much energy is in fuel.

1 kg of oil contains about 30 MJ of energy. enough to accelerate an object of the same mass to 7.7 km/s. which is almost escape velocity on earth (11.2 km/s), or enough velocity to shoot the object out of earth’s gravity field altogether.

(a kg of oil, ofc, costs about $1)

oh very interesting. i’ve been wanting to get into the details of how federation actually works, and i wanted to figure out why mastodon<->lemmy federation does often not seem to work. but i guess that’s a deep rabbit hole too!

we can’t even stop a rise in fascism because we lack the tools to do so, most importantly we lack the tool of understanding. we don’t even understand what fascism is or why people follow it, thus we stand no chance of tackling the problem at its root. if you really want to combat fascism, you have to understand it first.

the only real solution to climate change is renewable energy, and solar energy in particular. capitalism or no capitalism basically doesn’t matter.

so just to put this in context: we’re having a doubling of installed solar capacity around every 3 years. currently we have 3% of total energy supply from solar energy. so it will take maybe another 15 years to get close to 100% renewable energy (if we assume that exponential growth continues). source: ourworldindata (go to website and hover over solar energy to see numbers)

so we’ll end up in 2040 with roughly … let me do the math … 1.6°C total temperature difference compared to 1970 in 2040?
