That video has been removed. I am assuming its this one (Facebook video)?

10 electric cars for 2019 and beyond.

Almost all of these are "money is no obstacle" cars, and unlikely to be seen in NZ.

However engineers for these cars pave the road for typical consumers. I'd love to see these cars against a Bugatii hyper-car

Kalashnikov's trabant thing looks scary. 0-100 in 6 seconds if you dare.

Having a racing series seems to be an effective way of advancing development in things motoring. I know there is Formula E, and some of the advances made in that will trickle down to road cars, but how about a series for family sized cars, cars that the family with 2.3 kids may one day be able to afford. Maybe there is one already going that I haven't heard about yet.

Are Electric Cars Worse For The Environment?
Engineering Explained

Short answer. no, electric cars are better for the environment, even for coal produced electricity.

14 minute video. Oriented toward engineers. Lots of citations.

"Myth Busted: I put a ton of time into researching this video, and was surprised numerous times to learn about the differences in lifecycle emissions between gasoline cars and electric cars."

1) Doesn't producing electric car batteries produce a lot of emissions?

2) Are electric cars powered by fossil fuels, offsetting any emission benefits particularly relevent in Australia

3) Isn't lithium mining terrible for the environment?

Has an environmental analysis been done on if an EV is charged using diesel generated power? As some small Pacific island countries get most of their power from diesel. And lots of countries (including NZ) use diesel generation as peaking generation.

Surely a diesel car would be better for the environment than burning the diesel in a generator, just to get power for charging an EV.

A pretty upfront video, intentionally favouring the ICE, but still giving a clear result for the EV

Not aware and not needed. Racing allows high expenditure research to be carried out, that flows down to road cars. Traction control is one, regenerative braking is another, and no doubt more efficient ICE engines would be another. Safety as well I assume. There is a motorcycle EV series in 2019 MotoE I think its called, MotoGP, also the pinnacle, in a electric version

One day the entire globe might be solar powered, how cool would that be?

Isn’t it already?

With the possible exception of nuclear (and even its fissile material was produced in a star) all energy, stored or currently being absorbed, comes from the Sun. 😊

:-) yes correct!

Re phrased to global inhabitants energy consumption!

I've heard that an EV charged from a gasoline powered generator is equivalent to 77 MPG, because an electric motor is more efficient than an internal combustion engine.

In 2018, the average US car gets 23 MPG, with only hybrids getting 40 MPG or better.

I don't know how this compares to diesel.

About 2 degrees less than currently? ;)

But seriously, it looks like solar panels are more efficient at capturing solar energy than plants. Solar panels max out at about 22%, whereas photosynthesis is about 26% (https://www.britannica.com/science/photosynthesis/Energy-efficiency-of-photosynthesis), and only a proportion of plants' surfaces is chlorophyll. So every acre of land where green plants (or bare land or car parks) is replaced by solar panels will result in global warming.
