Should we increase production of renewable and clean sources of electricity before increasing electric vehicle (EV) numbers in the UK?
Yes, we should focus on clean electricity first
No, we should encourage EV uptake no matter what
No, we encourage EV uptake now and develop clean electricity at the same time
That’s the verdict of a new study by Carnegie Mellon University’s Jeremy Michalek, who determined that small battery packs could promote the adoption of hybrid electric vehicles and plug-in hybrid electric vehicles, ahead of plug-in hybrids and battery electric cars with larger battery packs.
According to Michalek, the study assesses how much externality damage reduction plug-in vehicles can offer in the US and at what cost. It gathered data on the quantity and location of emissions released from exhausts; the externality costs of damages caused by these emissions; and estimated other costs associated with oil consumption.
It then estimated lifecycle emissions damages for comparable new mid-size vehicles, including: a conventional vehicle; hybrid electric vehicle; plug-in hybrid electric vehicles with battery packs sized for storing enough range for 12miles and 37miles; and a battery electric car with a 149mile pack.
Under an optimistic scenario, the study suggested that plug-in vehicles with large battery packs could offer lower damage at lower lifetime costs – while under a pessimistic scenario, using low petrol prices, shorter battery life, and coal-powered charging; plug-in vehicles could produce more damages at a substantially higher cost.
As a consequence the report suggests that large battery packs offer the highest emissions and oil consumption reductions at the lowest cost but result in high costs and increased damages if not all the right factors fall into place. By contrast, hybrid electric vehicles and plug-in electric vehicles with small packs are robust and provide emission reductions at a lower cost with less infrastructure investment.
It points out that in the future, if there are sufficient decreases in battery costs and increases in petrol prices, the market may drive adoption of vehicles with larger battery packs. However, until then, a policy that focuses on small capacity hybrid electric vehicles and plug-ins may be more beneficial per dollar spent.Ontario to hand out electric car rebatesPSA Peugeot Citroen and General Electric team up for electric carsPlug-in vehicle sales to smash five million barrierHonda announces latest electric vehicle testing programmeBYD to reveal electric vehicle launch plansStudy looks at optimising plug-in hybrid vehicle designsVolvo reveals plug-in hybrid vehicle project detailsElectric vehicle market expected to surgeEast of England could receive charging point boostFord makes electric vehicle predictions
