What happens when 20 million electric cars are parked ?

in physics •  7 years ago 

1 to 2 million electric cars have been sold and are circulating. Maybe 20 millions ecars will be sold by 2020.

An ecar has a battery with a storage capacity of 24 to 30 kWh.
Cars are parked 95 % of the day.
20 millions ecars can store 20,000,000 x 30 kWh = 600 Gwh
This is about 60 % of the average daily consumption in France, a country of 67 million people.
These batteries can be used to store excess production of wind energy when the wind is strong.

We gotta figure out something we our infrastructure in the U.S. at least because we're living in the past with these fossil fuel vehicles. The future is Tesla and other electric vehicles. I know other car companies are starting to shift but it seems the infrastructure for electric vehicles is lagging behind. This means smart grids, autonomous vehicles adoption, better road ways, greenlots and of course renewable energy, wind and solar power.

You have to load the batteries with photovoltaic car port.
