dunno why this is even an issue
the global economy runs on carbon (oil, coal, natgas, whatever)
electric cars barely make a dent in lessening global burning of carbon
ocean freight -- those ships that carry container vans from port to port, you gonna put electric motors on them?
airliners -- you gonna power them with solar panels and electric motors?

let me rephrase this:
ocean freight -- those ships that carry container vans from port to port, you gonna put electric motors on them?
ocean freight -- those ships that carry container vans from port to port, you gonna put Li-ion batteries and electric motors on them?

global economy runs on oil coz it's the cheapest energy. unfortunately this cheapest energy is also harmful
fortunately solar+batteries keep getting cheaper. while oil gets harder and more expensive to get. guess what'll happen when they intersect
the transition isnt' going to happen overnight so don't worry too much LOL
airliners. check out the airbus electric called e-fan i think. simple and reliable electric motor. i guess you already know how complex and super-high-maintenance the jet engines are electric cars and planes operate with the same laws of physics, so why do you think electric planes aren't going to work? soon we'll start seeing cheap short-haul flights because these electric planes are going to be very cheap to operate
ocean freight. did you know that just the few numbers of those large ships account for a very large percentage of the world's pollution? and you wanna continue using them just because they're cheap

i know how harmful burning carbon is
me page 1
it took billions of years for plants to take enough carbon from the atmosphere to make Earth liveable for us
for the past 300 years we've been burning dead plants and releasing the carbon they trapped
during this change in climate, life will become harder
wars will be fought over water and food
it's gonna be uglyLast edited by uls; September 22nd, 2017 at 12:53 PM.

Maybe the engine won't be replaced but the source of fuel. Heard about those algae that produces fuel in their poop.

but still burning organic matter
corn and sugar cane ethanol and other biomass
cooking oil diesel etc

pero renewables are carbon neutral. it does not add more carbon to the atmosphere as what the plants it came from absorbed from the air.
ships? yeah no way. mas malaki/mabigat pa battery kesa sa cargo.
planes? again, the weight of batteries and motors. also those turbines are very reliable. have not heard of any turbine engines on planes giving up in mid flight for the longest time. and you want to replace them with electric? how many kw is one 777 engine? na google ko na, 110,000 hp. HOW BIG AND HOW HEAVY DO YOU THINK A 110,000 HP ELECTRIC MOTOR IS? naaaaaah, it won't fly. baka ni hindi gumalaw yan ng walang humihila hahaha!
