The Story of Energy (Part I)

"It's the economy, stupid" was a phrase coined as Bill Clinton's presidential campaign in 1992. As much as I want to agree, I too, wish the economy is the only to look at, and we can control it by pulling the lever of interest rate. In reality, the world does not work like this. It is a system. Economy, energy and environment have a relationship with one another.

If you know me in person, my background is engineering, not economics. Being a techno-economic hybrid, I see the world in a rather realistic way. One of them is the story of energy.

Question: do you have an idea about the required extra electricity production in a scenario where all road transportation is done by electrical vehicles?

 

[Cinvalo]

Results from electric vehicle trials show that EVs equivalent to a small petrol or diesel four-seat car use around 0.2 kWh/km in normal city traffic.

With EVs or equivalent mains electrical usage from PHEVs of 20,000 km per year, each would use 3-4 MWh/yr, so for each ten million cars thus depending on the grid an extra 30-40 TWh would be required, mostly off-peak.

Analysis by the Energy Supply Association of Australia (ESAA) found that an equivalent litre of electricity, or e-litre, could cost from 37 cents off-peak up to 62 cents with peak prices. It found that electric cars have the equivalent fuel costs of approximately 3 cents per kilometre, compared to 10 cents per kilometre for conventional cars.
