Do you own a Tesla? Or would you want to own one in the future?
I mean I like cars but I'm not sold on the idea of buying one Elon Musk manufactured 馃槄

All the lithium and nickel needed for batteries is causing strip mining and deforestation...meanwhile oilfields are already in place and after all electric has to be generated - and there's line loss in transmitting the power to the cars...so I'm not ready to make a judgement call on this yet..

@fun4us2b Electricity is generated from hydro dams

@justanothername I'm not saying we shouldn't try (we must) - but saying there's no free lunch...
From the internet (so it must be true)
[b] Hydropower currently accounts for 28.7[/b]% of total U.S. renewable electricity generation and about 6.2% of total U.S. electricity generation.
In 2022, about 4,243 billion kilowatthours (kWh) (or about 4.24 trillion kWh) of electricity were generated at utility-scale electricity generation facilities in the United States. [b]About 60% of this electricity generation was from fossil fuels[/b]鈥攃oal, natural gas, petroleum, and other gases.
I'd say this is a conservative number on power loss:
The U.S. grid loses about 5 percent of all the electricity generated through transmission and distribution鈥攅nough to power all seven Central American countries four times.

@fun4us2b have a buddy that's a utilities/power engineer, he figured we'd need a solar farm the size of new mexico just to replace existing fossil fuel energy production; and that isn't even accounting for extra space needed for power storage/batteries (let alone the cost). And due to the degradation of solar panels (which is far more than advertised), they'd all need to be replaced every 3-5 years...

@justanothername Not in all countries, and those who use hydropower may not be generating all of their electricity that way.

@fun4us2b 95% efficiency in national grid distribution - I'd have said that is very good indeed.
You don't say what is being measured. It may be overall from fuel, turbine or solar array to customers, or simply in the electricity from alternator and solar-array outputs to local distribution points. Nevertheless I think you should credit the system's designers, builders and operators for it having such high efficiency.
It is impossibly to make any engineering system that does not have losses, and though the amount lost in the USA's system seems staggeringly high in linear terms, it is only 5% of the electricity generated.
I would be very surprised if any country's equivalent exceeds 95% overall efficiency continuously throughout the year. (It may vary by season, especially on a continent that experiences very wide climates and daylight times. )
