I live in
Denmark. It’s not a sunny place. Lots of clouds and rain and so on. However, my
family only needs a 2,4 kWp system to serve our needs. It will cost our family
roughly 10.000 USD to buy and have it installed
on our roof. (I know, Danish prices are insane.) And by Danish standards
and prices, it would take about ten years to earn that money back.
However, if
we had an electric car. Things would be different, because solar energy = free
fuel.
The problem
is that we are using the car during the sunny hours. Which means that a lot of
energy is wasted, because we have to sell it back to the electric company. Of
course there is there are products like the Tesla Powerwall that lets you store
the energy for later use.
That’s all
great. However, I may have a better idea:
Selfdriving
cars are upon us. And that may even change the way we buy cars, meaning that we
don’t.
Let me
explain. Instead of buying a car, you lease one for a short while, and you pay
for each and every ride. Just like a taxi.
Now imagine
that these selfdriving taxis are electric vehicles. Wouldn’t it be great if you
could sell back your solar energy to the “taxi company”?
Meaning,
your bill at the end of the month would look something like this.
Fares: 100
USD
Energy
sold: 30 USD
You pay: 70
USD
The
technology is already here. The Tesla Snake Charger can charge the car without
human assistance.
So why not
do it? I get to sell my energy, and earn back my 10k a lot faster, and the
taxi/leasing company has charging stations all over town.
It’s clean,
it’s free and everybody wins - especially the environment.
