“We are on the cusp of one of the fastest, deepest,
. . . most consequential disruptions of transportation, in history.
But there is nothing magical about it.
. . . This is driven by the economics.”

By 2030,
. . . 1) 95% of people won’t own a private car, (killing off the auto industry)
. . . 2) Electric vehicles will devastate the global oil industry (upending two, trillion dollar industries).

As fewer cars travel more miles,
. . . the number of passenger vehicles on American roads will drop,
. . . from 247 million in 2020,
. . . to 44 million in 2030, and be
. . . 4 to 10 times cheaper per mile,
. . . than buying a new car.

The average American household,
. . . by giving up its gas powered car, will save
. . . $5,600 per year, in costs of:
. . . . . . Maintenance,
. . . . . . Energy,
. . . . . . Finance, and
. . . . . . Insurance.

I suppose it is nice to think of a positive future, in spite of data.

[eds]

Here is some positive data, on a current project.

Vermont, Green Mountain Power Utility (GMP),
. . . now offering GMP customers a Powerwall battery for the bargain price of
. . . . . . $15 a month for 10 years, or
. . . . . . ($1500 one time charge).
The normal price of a the 10 kWh Powerwall with built-in inverter is
. . . $5,500, plus installation.

Up to 2,000 batteries will be provided, and
. . . they will be linked together via the internet,
. . . so the utility company can use some of the power stored in them,
. . . to balance the utility grid and provide extra power when needed,
. . . while meeting all the needs of the homeowner.

The plan is similar to what is known as vehicle-to-grid (V2G) systems,
. . . that allow the batteries in electric cars,
. . . to feed power back to the grid when they are plugged in, but not charging.
Electric car batteries can also be used to provide power to the home if wired properly.
1) installation of Tesla Powerpack grid scale storage units,
. . . at substations throughout the area,
2) linking thousands of individual Powerwall residential battery systems.

Batteries can react in milliseconds.
. . . That makes them ideal for soaking up some of the excess electricity sloshing around the grid now,
. . . (2/3rds of all electricity is rejected) feeding it back into the grid later, and
. . . smoothing out fluctuating renewable energy.

Tesla GridLogic software platform, will help customers by using stored energy:
. . . . . . drive down the costs of the grid,
. . . . . . improve the comfort, energy use,
. . . . . . allows customers to generate, and
. . . . . . store their own energy, and
. . . . . . power their homes during outages.
Customers who allow Tesla, and the utilities to use their battery when energy demand is highest,
. . . will not only have home backup power,
but will also receive compensation for its use on the grid.
