Energy demand will not increase in the next decade. It will, instead, fall, as it has in recent years.
Electricity demand will increase as that takes over for other energy uses that will be collapsing.
Electricity demand will increase as that takes over for other energy uses that will be collapsing.
Primary energy demand will decrease because you do not lose 70% of the energy by simply cooling it like in steam turbine used by nuclear power plants or car engines.
On the other hand, electricity usage will increase because you have now replaced your 30-40% efficient engines with 90+% efficient engines, but from a different source. That barely have any losses from the primary energy input.
The change from 30-40% efficient engines to 90+% efficient engines is if we burn the oil in a power plant. It is an improvement, but not a sufficient big one compared to actually keeping the oil in the ground.
If you use some really high temperature chemistry, you can get to 5260 K from dicyanoacetylene in oxygen, which is 95%, but not gasoline. And dicyanoacetylene is a bit explody.
We are forced into poorly built, unrepairable appliances through a market failure.
Failure of consumers to spread the word about appliance repairability. Fraudulent forgery of consumer reviews by manufacturers.
Failure of the housing market driving the repair technicians out if business - its cheaoer for someone in china to spend 10 hours building new washing machine than for someone in uk to spend 2 hours fixing it.
In some cases, a deliberate subversion of the spare parts market by manufacturers.
There is not a grand plan to improve efficiency and solve clinate change.
But thats all they can do - suppose I want to fins out if a Samsung phone is more reliable than Fairphone or Huawei - how would I find out? Will their salesmen tell me the truth? would customer support? Does their marketing department publish mean time between failure or statistics for repair?
There is very little hard data where anyone took thousands of appliances and measured their reliability.
They've built up significant trust with their community, they're not perfect, but close enough that I'd trust their reviews blindly in domains where I'm not informed enough already. (Everything except their dabble into datacenter storage, virtualization and networking)
This is an accounting issue, not a question of thermodynamics.
Electricity typically refers to grid electric. We don’t count non plug-in hybrid electrical output as “electricity.” That’s how energy use can be stable while electrification increases.
