Plug-in Hybrid Electric Vehicles — worth it?
I was discussing with a colleague that I want to purchase an electric car, otherwise known as a plug-in hybrid electric vehicle (PHEV). In terms of reducing the cost of operating the vehicle, PHEVs rule: the electricity used is like getting gas for less than a dollar. With respect to reducing greenhouse gas emissions, it’s not as clear. After discussing how in the US, electric vehicles would still get most of the energy from coal, I read some more to get a bigger perspective. To really benefit from reduced greenhouse gas emissions, we’d need to have a low carbon energy infrastructure via renewable energies (e.g., via solar, wind, hydro technologies). To see a more detailed analysis, see this site. Or see my slide deck that has their charts.
I’m looking forward to keeping up with news about PHEV technologies, especially a vehicle with a solar panel sunroof.
