| Production of batteries is the constraint ... previously, currently, and in foreseeable future (<5-8 years). Simply don't have the capacity to make 100% EVs. Further, given this capacity, the numbers work out such that we are, on the macro level, DRASTICALLY more fuel efficient and environmentally friendly by putting more hybrids and Plug-in Hybrids (which have fewer batteries) on the road than we are by reserving said batteries for fewer pure EVs. 2.5 Priuses are better than 1 EV. When battery technology and production capacity are NOT the constraint, then pure EV will make sense. All cars should be mandated hybrid soon (or all manufactures must meet a minimum hybridization level across their line ... sort of like fuel efficiency standards are measured today). All cars should be mandated Plugin Hybrid at some point after that. Maybe someday, we can mandate Pure EV. |
