The calculation leaves out major costs, such as expanding and strengthening the power grid to handle far more complex
flows of
electricity from millions of solar installations, and creating breakthroughs in energy storage technology to lengthen solar power's impact beyond the daylight hours and to deal with sudden drops in output
when clouds arrive.
To salvage some of that energy, the team added a regenerative braking system:

We're not sure about Nissan's claim that e-Pedal will make driving more exciting, but we do agree
when they say it will make driving the LEAF simpler and more engaging: in our experience, one - pedal driving forces you to pay closer attention to the

flow back down through the turbines to generate more
electricity at times of higher demand.
Here's how it works: water
flowing downhill from the reservoirs will power the hydro plant
when electricity is needed.
