Tesla’s goal is to have solar panels, or their solar tiles, on every house and they all feed into the grid.
This would supply enough power for everyone no coal required. Will it happen? Probably not, too many fat and wealthy coal plant owners.

Great question. If you used coal fired plants equipped with scrubbers, you would dramatically reduce point source solution via internal combustion vehicles across the world. It is far easier to place a complex emission control system on a stationary power plant than a moving vehicle. So this would be a vast improvement over the millions of trucks right now putting out diesel engine particulates as well as sulfur oxides.

Solar is unreliable and depends on the weather plus solar panels are made from MINED silicone...which is not renewable.
They only way electric cars will truly save the planet is if some new fuel source that is renewable AND doesn't pollute is invented.
Fighting global warming in reality is a lost cause.

Actually it has nothing to do with "fat and wealthy coal plant owners". I have worked in the solar panel industry for years. Photovoltaics are a great source of power but aren't perfect. Their power output, though significant, is nothing like that from combusting oil or coal. And what happens when the sun goes down? That is why so much effort is being made on energy storage systems.
The typical solar panel using polycrystalline silicon puts out about 100-140 watts under best condition (direct sunlight). The Tesla truck uses a claimed 2 KWH per mile- or the equivalent of 20 solar panels running one hour. A long haul trucker does 600 miles per day, so you need 1200 KWH or the combined output from 1000 solar panels for 10 hours.
It's about math, not politics.

Not exactly true. The dirtiest process in the production of polycrystalline silicon solar panels is the production of pure silicon in the first place. It's about equivalent to steel production, so yes it can be dirty. But once you have the silicon it can be used indefinitely. It is converted to polysilicon by a fairly clean process (I have been to the plants in China) and from there it's nearly done as a production process- producing panels is fairly clean.

The word is "silicon" and it is the second most plentiful element on earth. Remember, sand is mostly silicon dioxide. I know where you can get a lot, lol.
And "solar is unreliable"? Well, the sun comes up everyday, so that's pretty reliable. If it doesn't, we won't have to worry about driving anyway.

The only current industrial process that can generate the dense energy requirements of a technological society without burning anything is nuclear fission...

Well if you look at the math solar panels are getting better everyday.
Also I believe the idea is to save enough power in batteries to get everyone by.
I don’t work in solar so if that is possible. Idk

What's your prediction on batteries? Is there going to be something affordable and generally kick-ass in the next 10 years?
I have a 20 kw lead acid bank in pretty good condition I got cheap. The weight, size, expense, and small percentage of discharge permitted would have put me off buying these things at retail price.
Also what are your thoughts on thin film panels? They seem to be popping up at auctions in my area.

Five countries had about 75% of the world's coal reserves:
China—23%
United States—21%
Russia—14%
Australia—9%
India—8%
As of January 1, 2017, the demonstrated reserve base of the united states was estimated to contain 476 billion short tons.

BS, incorrect statistic: China & India import coal from Australia

Coal is on the way out, in well run countries anyway
Solar, hydro power and wind can generate the electricity for all things electric. Tesla powerwall home storage can store excess energy.

Marques Brownlee uploaded a terrific review:
Tesla's "one more thing"....Apple hasn't come up with anything remarkable in years....Apple's only about tax evasion and greed. Very dissappointing
Tesla is making one game changer after the other, the entire German car industry is copying Tesla
Tesla is forcing all other to change and innovate, which those old fashioned and often corrupt companies don't like, but they have to

A fat man would go straight through a solar tiled roof.

Major energy sources and percent shares of U.S. electricity generation at utility-scale facilities in 2016
Natural gas = 33.8%
Coal = 30.4%
Nuclear = 19.7%
Renewables (total) = 14.9%
Hydropower = 6.5%
Wind = 5.6%
Biomass = 1.5%
Solar = 0.9%

I guess America isn't a well run country. We still get 30% of our electric power from Coal.

Tesla Semi Has A 500-Mile Range And Hits 60MPH In 5 Seconds
By Brad Anderson
First, the most important number of them all. 500 miles. According to Tesla, that is the official range of the Tesla Semi under highway conditions when it is towing its full 80,000 lbs load. When fully loaded, the semi will reach 60 mph (96 km/h) in 20 seconds, far quicker than any diesel semi-truck on the market. Remove the trailer and it’ll reach the same mark in five seconds.
Another interesting thing about the Tesla Semi is that Musk says it will be impossible for the vehicle to jackknife. In order to avoid this, the Semi will use its independent rear wheels to dynamically adjust torque to ensure a jackknife never occurs.
Unsurprisingly, every Tesla Semi sold will come with Enhanced Autopilot as standard. Consequently, the Semi will include automatic lane keep assist and autonomous braking.
Despite being the brand’s first attempt at a truck, the Tesla Semi will allegedly be incredibly reliable. In fact, the automaker will guarantee that it will not break down in the first million miles. Owners will also benefit from the brand’s new Megachargers, powerful chargers which can add up to 400 miles of range in just 30 minutes.

Price of renewables is going down very quickly
Here in Holland large companies / mulitnationals are signing contracts to buy power from wind turbines
Brands like IKEA and German Aldi are covering their roofs with solar cells, and offering customers (sometimes free) power for electic cars
Coal has anormous hidden price tags, both for air pollution and for climate change
Major hurricanes, fires and floods can easily cost hundreds of billions of damage
Just a matter of time till even a psycho like Trump will get the message

That 'truck' looks gender-neutral.
This is how a real truck should look like,

These type of trucks will be used for short term loads, like the hundreds of trucks that pick up from the Ports of Los Angeles and Long Beach and deliver around the Southern California area.
Yes, solar power is getting better, and the key, as he said is solar storage, which is also getting better in terms of technology.
It may not work up in the colder states, but down here in California, there can and is a place for these trucks.

Given the right area and miles traveled per day, these trucks are really impressive. Still, 500 mile travel length is a very short range for most semi trucks. Wonder if Stallone would have accepted this as his new big rig on Over The Top?

An Enhanced Autopilot system would handle lane-keeping duties and apply the brakes if needed. From this perch, a driver can pilot the truck for 300 or 500 miles, depending on variant, then dump 400 miles into the massive under-cab battery pack via a 30-minute charge courtesy of the currently hypothetical Megacharger network.
According to the American Transportation Research Institute, 62 percent of U.S. pickups and deliveries fall within the longer-ranged model’s range.
Wowing the assembled journos and Teslarati, company CEO Elon Musk touted the truck’s scorching acceleration times — hardly top of mind for fleet operators, but this is Tesla, after all. The company claims a 0-60 mph time of five seconds for an unburdened rig, or 20 seconds hauling a trailer bursting at the seams. On a 5-percent grade, Tesla says the Semi can maintain 65 mph.
Speed is nice, but cost is key for any operator. And unpacking the Semi’s economics proved difficult. The operational cost figure tossed out by Tesla is $1.26 per mile, with rival diesel models pegged at $1.51. Chalk up the difference to reduced fuel costs (Tesla claims a $200,000 fuel savings over the life of the vehicle, which is guaranteed for 1 million miles), plus reduced maintenance. As the model employs regenerative braking, Musk touted the Semi’s brake pads as having a “quasi-infinite lifespan.”

What Tesla deliberatly didn't mention is their intention to make driverless trucks. They probably did not want to scare / put off truck drivers, but....in crowded small European cities an autonomous truck would be very difficult
But in North-America with loads or space....imagine a fleet owner with say 200 trucks. And most of them driving to and from large factory sites or industrial areas / distribution centers...95% of the time on highways that are not too busy
Tesla trucks can charge during loading and unloading
And without a driver they can run 24/7
Huge savings per year for fleet owners
Very little brake pad and disc wear

The generation of the electricity is not the problem it all. It is the electricity grid.
We are spoiled by our coal, nuclear and gas fired plants. We generate energy as we demand it.
Changing to 100% renewable energy will require a huge change in our behavior.
