The EV Transition Explained: Policy Roadblocks

Cars That Think

“Public policy implementation is hard even if everyone supports a policy,” says University of Michigan professor emeritus John Leslie King , who has studied policy management and administration for decades. Reproduce that across the numerous EV-involved industries from mining to recycling and the complexity involved becomes clearer.

Greenlings: Benefits of charging stations vs. battery swaps vs. home charging

Tony Karrer Delicious EVdriven

↓ ↑ report 6 jzj 3:24PM (4/15/2009) Polo, First, there will indeed be need for such fast charging at home because the future of a renewable energy grid will depend upon V2G energy storage, and that will require fast in-out charging. Second, the statement "the rest of your claims" are unanswerably indistinct.
