Tesla Chief Executive Elon Musk said on Tuesday that electricity consumption will double if the world’s car fleets are electrified, increasing the need to expand nuclear, solar, geothermal and wind energy generating sources.
Increasing the availability of sustainable energy is a major challenge as cars move from combustion engines to battery-driven electric motors, a shift which will take two decades, Musk said in a talk hosted by Berlin-based publisher Axel Springer.
There’s no unicorn energy source or free lunch. Currently, electric cars are primarily powered by coal, natural gas, and nuclear. Those are the sources we use to generate electricity, after all, according to the Energy Information Agency. Renewables are growing but still account for less than 20% of U.S. electricity.
There’s no free lunch when it comes to renewable energy source, which may not even be all that renewable. Wind and sun are free, but the means of generating power from them are not.
They require batteries, which requires extensive mining and the use of toxic chemicals.
Mining is a dirty business.

Tens of thousands of aging blades are coming down from steel towers around the world and most have nowhere to go but landfills. In the U.S. alone, about 8,000 will be removed in each of the next four years.
...
the blades can’t easily be crushed, recycled or repurposed. That’s created an urgent search for alternatives in places that lack wide-open prairies. In the U.S., they go to the handful of landfills that accept them, in Lake Mills, Iowa; Sioux Falls, South Dakota; and Casper, where they will be interred in stacks that reach 30 feet ..
Removing them and transporting them to landfills increases windmills’ energy footprint over time.
...
more electric cars will require more electric generation.

The overall efficiency for a Tesla should take in account the efficiency of the generating plant supplying the electricity.
even if every home plugged in one or two on 110-120 volt lines, it would be too much.
those transformers need down time
plus they are not designed for all homes to be putting such a heavy constant load on them
which is why you fridge or a/c in all homes is ok, because they switch on and off, and only have surge demads on startup, then taper down
these chargers charge constantly high for multiple hours, no breaks or rampdowns
When your gas powered vehicle runs out of fuel, you grab the gas can and start walking, or somebody delivers a gas can to you, or you get a tow.
When your battery powered vehicle runs out of “gas,” you get a tow.
Depending where you run out of gas, or “gas,” you may be stuck.
With gas, instead of “gas,” you are less . . . stuck.
Why? I own a S60 that has nearly identical load capacity and luxury as a model 3. The Model 3 brand new cost less than what I paid for my S60 new. My S60 gets 30mpg and at $1.60 a gallon just in fuel costs 5.3 cents per mile, this doesn’t include oil changes or other maintenance that is required for an internal combustion engine. I get all the power I ever need from my rooftop solar panels a 15 kw system that generates in a good sunny day over 120 kWhs worth of electricity. I pay 3 cents per kwh consumed over a 20 year power consession. When I purchase the model 3 I want my cost per mile in energy will be 3 cents divided by 4 miles so 0.75 CENTS per mile or SIX times cheaper than gasoline at $1.60 a gallon. This is from a car that is already CHEAPER to purchase new than the vehicle I already own. Even paying the current retail electric race in Texas of 7 cents per kwh 7/4= 1.75 cents per mile still cheaper than gasoline. For gasoline to equal the same cost per mile as retail 7 cents per kwh at 30 mpg gasoline would need to cost 53 CENTS per gallon not going to ever happen. Electric cars are already CHEAPER per mile every mile they drive that’s just physics second law vs third law. In my case at 3 cents per kwh gasoline would need to be 23 cents per gallon to have the same energy cost per mile. Remember the model 3 is cheaper brand new than the car I bought new two years ago with identical seating capacity, load carry capacity and is actually faster significantly so from 0 to 100 mph than the S60. Plus never having to change oil, filters, spark plugs which in a Volvo is a $900 job at the dealership. The Model 3 has a 8 year unlimited mileage warranty and Tesla has designed the packs to go 500,000 miles with commercial Teslas already hitting 500k miles on their original packs. They plan on one million mile packs for the gen two model 3/s/y lines. NO retail ICE vehicle will go one million miles on its original engine and transmission without significant rebuilds. Tasks will warranty the drive train for one million miles in commercial service for the motors and packs. The Model 3 motor is the same as the commercial trucking axle motor that they already are designed for a million miles for the class 8 tesla truck.
Calling Captain Obvious.
I know! We can put little wind turbines on electric man’s cars and while they drive they can generate their own electricity!

Given that combined cycle natural gas power plants are 60+% efficient based on a HHV of the gas they burn. Transmission losses over high voltage AC lines is 2 to 8% depending on distance. So at worst for a modern gas turbine plant it’s 52% plant to plug efficiency. Then the gross consumption of 250 watt hours per mile. Convert that to btu per mile is 853 btu per mile.
I own a S60 Volvo that gets 30mpg on E10 @114,000 btu per gallon. 3414 btu per kWh for 33.39 kWh per gallon. This is equal to 1113 watt hours per mile or in btu form 3800 btu per mile.
853/52% = 1640btu vs 3800 in raw HHV btus again second law wins every time. In the USA we get 38% from natural gas, 19% from nuclear, and 17% from renewables so it’s a myth that EVs are coal powered the facts show that they would be nearly 75% powered by zero or nearly zero emissions power sources. Gas turbines emit much less NOx, SOx, particulates due to the lean combustion process and mandatory scrubbers at power plants that cannot be used in a ICE engine especially millions of them. My new EV will be 100% powered by my roof panels since they make nearly 130 kWh per day on a sunny day and we get 220 days of full sun per year in North Texas according to the NWS climate data. My home uses at most 50 kWh per day in August with the AC roaring at 68 degrees set point. This means 220 days per year after running my home my panels will have made 80 kWh available to the EV PER DAY that’s 320 miles PER DAY of range 220 days a year.that’s 74000 miles per year of solar driving range from my own roof top. I drive 36000 per year. The Model 3 LR version has a 310 mile range in full summer heat it’s pack is liquid cooled it doesn’t matter if its 100+ outside the pack is climate controlled.
Ethanol costs about $1.50 worth of gasoline to produce and transport a $1.00 worth of ethanol fuel. What's the point?
Windmills can only be run in moderate speed winds. They rust and have to be dismantled and replaced every so often. There is no battery big enough to store much of their energy. The distribution system from windmills to a point of use is cost prohibitive. They are eyesores, bird killers and there is no place to dispose of them when they get too old to operate. Not very sustainable.
Solar only works with taxpayer subsidies and credits. The cost to supply full power to a commercial building or residence can be so expensive that just using regular electricity and natural gas can power a house for 50 years before the cost of the solar is recovered. Who lives in a house for 50 years? And the systems have to be replaced and repaired over time, raising the initial costs significantly. Not very sustainable.
Fossil fuels are the most inexpensive and efficient fuels to run our economy. Don't try to fix what is not broke.

My panels on the roof cost 35 cents per watt capacity bulk on the pallets. The two 8000 watt inverters that back feed to the grid cost 50 cents per watt. My 15 kw system makes its full rated power 220 days per year in North Texas at full sun and still makes 2 to 3 kw under partly cloudy skys. The installers did the job in two days and the electricians took two more to grid tie two 200 amp panels. I leased my roof top real estate to the solar power company. They played for the panels and inverters I happened to see the invoices that’s why I know what they paid for the system. Install was general labor at $20 hr and electricians were $80 hr. In exchange I get all the kWh I can use at 3 cents per kwh and they sell anything that I don’t use to ERCOT at what ever peak rate they bid up too. My panels make 120 to 130 kWh per day in full sun and DFW gets 220 or more of those days per the nws climate center per year. My home never has used more than 50 kWh in a day I have twin system ground source heat pumps that are amazingly efficient keep my home at 68 all summer and 75 in the winter months. At a retail rate of 7 cents per kwh the pay back period would be 7.6 years if they sold all the power at 7 cents , peak rates for summer ERCOT bid can be $130 megawatt hr or 13 cents per kwh or more. Solar never curtails first by law so they always get the highest leaker rates from ERCOT the payback for a 15 kw system would be 5 years or less in sunny Texas. These Panels have a full 25 year Warranty and have survived 70mph winds and golf ball sized hail in fact the area of roof that were not covered in panels had to be replaced after the golf ball sized hail we got in April the panels saved the roof under them in this case. Not a single panel has failed in the two years they have been up even after hail of that size.
In order to have a range of ~300 miles on a charge, you have to buy the long range Model 3 for almost $50K. One can buy an ICE car for $25K and have plenty left over for fuel and maintenance.
Because as the headline states, we don't have the available power, we do have the gas.
How's it do, melting the ice off the windshield, and with the heater running constantly?
How is electricity generated?
Well, DUH!
Elon, did it take you all this time to figure that out?......................
Now he tells us!
Watch “Planet of the Humans” on youtube. This is a Michael Moore documentary which does a good job of debunking the alt energy crap.
I can’t help but think that outlawing ICE cars and then not having enough juice to charge your EV is all part of the plan.
“Actually, the same amount.”
Wrong. Electric motors are much more efficient.
Technically, yes. From the same guy in the previous video I shared, he touches on that. But still...

He acknowledges that if a gasoline engine was as efficient as an electric motor, a tank of gas would get you across the country.
