You don’t really know all that gillybob. People have replaced the batteries in 2011 Nissan Leafs, so they are not scrap. There isn’t much to go wrong with an electric car, apart from the battery. We do know how long they last, because Nissan, for example, guarantees a battery will have at least 66% capacity after 8 years or 100,000 miles. Buses and lorries aren’t the biggest polluters, cars are. Many buses do not make long journeys. Provided you understand what you’re getting and pay the right price, a second hand electric vehicle is viable. There are enough sources of renewable power around the UK, without using dubious biomass. Yes, we need further technical development and more infrastructure, and we may use other techniques such as hydrogen power, or electric overhead cables. But it is a mistake to underestimate electric vehicles.
