Depends where you live and whether you think global warming is real.
Even if you do think global warming is real, in a lot of places getting an electric car just moves the carbon dioxide upstream to the coal powered electric plant.
Here in Tennessee it would actually be practical to get an electric car if your objective is reducing carbon dioxide emissions. A lot of our electricity comes from water power.

One of the appeals of the electric car is its simplicity. (I would never buy a hybrid car because of its complexity: gas power + electric power + transitional devices. Its like driving around in the space shuttle.) If you are a do it yourselfer, there are kits you can buy to convert certain car models to electric. Might be a fun hobby. I think one way to go, if you can afford to do so, is to have two cars, one gas, one electric; one for long hops, one for short. One downside to electric, eventually you have to replace all the batteries which is a big bill to pay. Also the battery manufacturing industry is a dirty industry, so that negates the environmental incentive. Nothing is perfect.

This is an accurate depiction of what it takes to power a car. In the end, after considering every aspect of the electric utility that powers the car, there may be an even greater carbon footprint than a car with an internal combustion gasoline or diesel engine. Also, into consideration is all of the mining of lithium, transportation, manufacturing, etc. Not to mention all of the battery fires that happen all of the time. Noxious fumes for sure.
but the oil IS going to run out, isnt it?
or it costs too much to get it.
so you do need an alternative, plus, dont you use batteries in your cellphone, laptop etc? And charge those up.
Its. it like you can go harpoon a whale as people did that for their oil and now theres hardly any left. The next biggest creatures were dinosaurs, and the fossils have already been mined and running out of those.

Do you have any idea of what it takes to make install those windmills? Here in the USA the stupid do gooders are pushing to do away with hydropower.

Probably the best post ever published on the subject of "zero emissions". Absolutely worth the read!
(Translated from English):
“Batteries don’t create electricity – they store electricity generated elsewhere, especially through coal, uranium, natural gas-powered power plants, or diesel-powered generators.” So the claim that an electric car is a zero-emission vehicle is not true at all.
Since forty percent of the electricity produced in the USA comes from coal power plants, therefore forty percent of electric cars on the road are coal-based.
But that's not all. Those of you excited about electric cars and a green revolution should take a closer look at the batteries, but also wind turbines and solar panels.
A typical electric car battery weighs a thousand pounds, about the size of a suitcase. It contains twenty-five pounds of lithium, sixty pounds of nickel, 44 pounds of manganese, 30 pounds of cobalt, 200 pounds of copper, and 400 pounds of aluminum, steel, and plastic. There are over 6,000 individual lithium-ion cells inside.
To make each BEV battery, you'll need to process 25,000 pounds of salt for the lithium, 30,000 pounds of ore for the cobalt, 5,000 pounds of resin for the nickel, and 25,000 pounds of ore from the copper. Overall, you have to dig out 500,000 pounds of earth’s crust for a battery. "
The main problem with solar systems is the chemicals used to turn silicate into the silicon used for the panels. To produce sufficiently pure silicon, it must be treated with hydrochloric acid, sulfuric acid, hydrogen fluoride, trichlorothane and acetone.
In addition, gallium, arsenide, copper-indium-gallium diselenide and cadmium telluride are needed which are also highly toxic. Silicon dust poses a hazard to workers and the plates cannot be recycled.
Wind turbines are the nonplusultra in terms of cost and environmental destruction. Each windmill weighs 1,688 tons (equivalent to the weight of 23 houses) and contains 1300 tons of concrete, 295 tons of steel, 48 tons of iron, 24 tons of fiberglass, and the hard-to-win rare-earths Neodym, Praseodym, and Dysprosium. Each of the three blades weighs 81,000 pounds and has a lifespan of 15 to 20 years, after which they must be replaced. We cannot recycle used rotor blades.
These technologies can certainly have their place, but you have to look beyond the myth of emission freedom.
“Going Green” may sound like a utopian ideal, but if you look at the hidden and embedded costs in a realistic and unbiased way, you’ll find that “Going Green" is doing more harm to the Earth’s environment than it seems. Has.
I'm not opposed to mining, electric vehicles, wind or solar energy. But I show the reality of the situation.

why are you doing away with hydropower?
seems silly
I dont know much about windpower, but I havent heard of many windmill accidents, though mining explosion disasters and nuclear meltdowns are common.
With hydro, rivers do get diverted. But thing is seems renewable.
so hydropowered cars might be way to go. I thought we'd all go magnetic in the future, wasnt there something called maglev.
even if we went to electric, cutting toxic emissions would be better than doing NOTHING if not for the air that we breathe. yOu want to keep choking on acid rain and smog, well up to you.

there could be an experimental town that just runs on maglev before trialling it in other areas.
could work
the roads or routes just need to be magnetic thats all. You just program your car where you want to go, the car figures out the route and the magnets at each 'stop' then pull the car towards its destination, because of its attractive force.

Green technologies aren't exactly that Green as stated above. TN doesn't actually get most of its juice from dams....it comes from a blend of coal, Natural gas, nukes, and dams. TVA is government power....electricity generated by the government run power plants. It's fairly expensive juice too. Currently TN has too much juice generating capability and doesn't operate most of its coal plants.
Aluminum is the issue that nobody wants to really address. Smelting aluminum puts out gasses that are worse than any carbon dioxide producing system and all "green" energy systems use a LOT of aluminum. Same as the hexathanes that refine silicon for computer chips.
Outside of South Chicago they have a huge windfarm as far as the eye can see....but it only produces enough juice to power 200,000 homes.
It takes a LOT of windmills. The repairs and maintenance make it a losing proposition every time. The broken blades are filling up landfills now.
However....
The new battery technology is cool...batteries are more efficient than ever.
The new electric motor technology is awesome as well. Much stronger and efficient electric motors has come out of this race to build electric cars.
The hydrogen hybrid fuel cell cars...
The fuel cells can turn alcohol or petroleum into electricity very efficiently....and it's better to use ethanol than petroleum products.
Because when the membranes in the platinum laced fuel cell become contaminated...you need another fuel cell. And most gasoline and diesel has contaminants. Ethanol, if mass produced to replace petroleum, will create famine as farmable land goes to energy production. And we still need the petroleum products for fertilizer and tires.
What we need to do is drill....and do a lot of drilling. Also begin turning yellow coal into diesel. (We can't use yellow coal for anything currently) yellow coal diesel is around 70/Barrel and cleaner than Brent.
Government taxes, fees, and regulations have choked the power generation systems in the world. (Not to mention graft...ahem Hunter Biden)
Oil is replaced over time...it's self generating. Heat and pressure create the deposits. It's not made from dinosaurs. Coal is...and coal also makes drywall. Just saying.

what
ok i thought oil was made of fossils (not necessarily dinosaurs, but compressed organic matter) so basically, God needs to send another big flood to press more oil since its formed under buried sediment.
right? Just so we can move around, rather than use our own hands and legs. Wouldnt it have been more efficient if we had wings and could just fly anywhere we wanted? You'd think.
it is costing too much to drill apparently and fracking is too risky. Basically all the gooey stuff near the surface is nearly gone.
Unless YOU wanna pay for it.

why would ethanol create famine
surely it is a byproduct of alcohol or whatver is already produced, so, its not costing anything extra to produce it. its just using a resource already available. You could use human manure to power things even, like how cow dung is used as fuel.
use whatver is being thrown away as fuel, like what happens to all that plastic packaging or what not.
