Will electric motors ever be able to generate enough force to replace fossil fuels in areas like airlines and cargo ships?
What's the most promising source of energy when we inevitably run out of oil?

>Will electric motors ever be able to generate enough force to replace fossil fuels in areas like airlines and cargo ships?
Yes. Many ships already do use electric transmission, and the power-to-weight of modern electric motors is definitely high enough to replace the engines in propeller aircraft.
The hard part is generating the electricity to power the motors.
>What's the most promising source of energy when we inevitably run out of oil?
Hard to tell. That depends on geography, economics, and what technological advances we get to see.

Motors aren't the problem, batteries are.

Electricity isn't an energy SOURCE. But if you mean energy CARRIER, I think batteries will gain prevalence in less energy-intensive applications, while more energy-intensive applications such as aviation will continue to use combustable fuels, albeit from non-petroleum feedstocks. Even fucking seawater can be turned into jet fuel if you pour enough energy into it: nrl.navy.mil

I imagine you'd need a pretty big battery to fly a passenger plane for 14 hours straight.
I said it like that referring to a source of kinectic energy, but I guess you are correct.
Also that's a pretty interesting article, I don't understeand the actual science behind it of course but the fact that that's possible is pretty cool.
Makes me think...How comes those big ass ships don't have systems to produce hydraulic energy in some way? Or they do?

What's that?

Battery-electric aircraft are probably never going to happen, with the exceptions of UAVs and maybe very light planes. However, chemical fuel cells could potentially power short-range commuter aircraft.

What do you mean by "produce hydraulic energy"? I'm sure any large ship has numerous hydraulic pumps onboard.

Making more oil.

Steering is usually hydraulic. Sometimes transmission, too. Hydraulic bowthrusters are not uncommon. You'd be hard-pressed to find a single big ship without at least one hydraulic pump aboard.

Even for light electric airplanes, batteries are hard-pressed to even meet basic reserves for a short local flight (30 minutes in clear daytime weather, 45 in all other circumstances), let alone yield enough endurance on top of that for any semblance of practical cross-country flight between airports.
