Question Three

摘要

The logistics of setting up, say, a hydrogen supply network are often cited as one reason why electric vehicles and hybrids are seen as a likely way forward, rather than more radical technologies. But what are the wilder implications on, for example, the electricity supply industry or metals and minerals producers or the urban infrastructure of a large-scale switch to battery-powered vehicles? Phil Stones/Steve Elmes, Millbrook: The take up of EVs by the general public in the UK on a greater scale provides both challenges and opportunities. Currently the national grid and associated infrastructure could not support an EV on charge in every household, so there needs to be a long-term strategic decision to upgrade the grid.
