Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

You're thinking too small with LED lights and heat pumps.

Overall energy consumption still has a long way to drop if we continue to electrify transport. Oil is consumed very inefficiently in internal combustion engines and electric motors are far more efficient. That's even before you account for the energy consumption of refining and transporting oil, all of which would vanish. Even if you just took oil out of the ground and pumped it into a furnace to generate electricity, then use that electricy to move everyone around, we'd drop our consumption significantly.

The setup with have now is desperately inefficient.

I guess I could have stated the form of energy I was talking about a little more clearly. That's actually mostly in agreement to what I was referring to though, as we move from fossil fuel powered transport to EVs, we'll see that demand shift and drive electrical consumption up dramatically (even if the total joules of energy required decreases from a physics perspective). Yes, internal combustion is inherently very, very inefficient but it just takes HEAPS of energy to move 3,000+ pounds (1,350+ kg) of anything and all of that will be coming from the mains rather than an oil rig. That's why we (not just Sweden, all of us humans) need to increase our electrical generation capacity and modernize our distribution networks.
