Coffee talk today was around how much electrical power generation for light road transport would be needed to replace gasoline.
So we googled:
The US Energy Information Administration says 337,000,000 gallons of gasoline is used per day and 92% is light duty vehicles.
Let's say 310,000,000 gallons. We guessed combustion engines are maybe 35% efficient now so multiply x 35% = 108,000,000 gallons electric equivalent energy to vehicle power?
wikipedia describes a "gallon equivalent" of gasoline is 32.78 kw/hr for E10 gasohol (10% ethanol).
So 32.78 kw/hr x 108,000,000 = 354,024,000,000 kw/hr or 354,024 megawatt/hrs per day of generation required?
The largest generating station in the world is the Three Gorges Dam in China at 22,500 MW.
So will we need 15 more stations this size equivalent?
I'm not that smart in math -
