   280 million e-bikes are slashing oil demand far more than electric vehicles

   E-bikes and scooters displace 4x as much demand for oil as all of the EVs in the world.

     @arstechnica How is the electricity generated? Hot air?

     I’m disappointed that people haven’t figured this out sooner. Tesla is the ultimate meme and its stock should be at like $0.50, not $225 or whatever it is

     The only application where electricity makes sense for linear propulsion is the railway engine, where the diesel power-plant is on the same frame with the DC traction motors. The electricity is consumed the instant it was generated, and it is generated at the rate it is required. You will find no other application in the same category, all other applications are for a niche (research submarines, space exploration, toys).
     
     Diesel has the self-life around 12 months, electricity has zero shelf-live. Diesel is stored in cheap and plentiful stainless steel containers while electricity is "stored" in rare-earth cells, balanced by complex circuits. Internal resistance, leakage between the cells and by the balancing circuits LIMITS the maximum power or energy productions, which means you will not find comparable power plants. The crude tanker's diesel, which is running on its own cargo the crude, some of which exceeds 100,000 HP.
     
     At that level V=IR would require you to build with copper conductors which are an inch in diameter, and your active electronics would have to be build with transistors where the traces are 30 gauge wires.

     "By joule" also depends on the source.
     You can't charge an internal combustion engine with hydro or solar.
     Electric is indeed more efficient, way more.
     Best you can get with an internal combustion engine is 35% efficiency. Electric motors – 90%.

     EVs convert over 77% of the electrical energy from the grid to power at the wheels. Gasoline vehicles only convert about 12%–30% of the energy stored in gasoline to power at the wheels.

     No, its not more efficient. Its FAR LESS efficient.
     
     Battery-generated electricity is far, far, far more expensive by joule than combustion of any kind - two stroke or four, gas or diesel.
     
     Its NOT cleaner. As long as its lead-free (and for the last 60 years all fuel are led free) the emission is water and carbon dioxide (plant food) and soot (also sort of plant food).
     
     What kinda "inventor" are you?

     It's far more efficient. Mainly because of the weight.
     The alternative would be 2 stroke motors that are unhealthy af, and far more inefficient.
