Boris ‘I talk bollicks’ Johnson (you think Trump is bad !) has decided
that Britons won`t be sold diesel, petrol or hybrid cars after 2035 mainly
so he an showboat at the November COP (out) conference .This is a
pointless fantasy as there isn’t enough lithium , nickel or cobalt on the
planet to replace even the UK`s cars , the price of them will be so high
that only the rich will be able to afford them so most people will be back
on their bikes...
hybrids are dubious (and widely misused) technology
there is plenty of lithium, it just isn't being mined
I guess that those that are used only (or mainly) in the 'self-charging'
mode (ie rarely charged from the mains) are probably best thought of as
petrol/diesel vehicles with battery-assisted acceleration when required,
and for fairly short distances on battery alone (most useful when
driving in built-up areas). This greatly minimises high pollution.
However, for distance travel on the open road, they can't travel all
that far on battery alone - so when the battery is flattened a lot of
fuel gets used for charging (with the associated increase in pollution).
Unlike 'conventional' vehicles, a hybrid has to lug around the
additional weight of the battery, and this morning on the radio (Nick
Ferrari's show I think) one guy reckoned that, when charging, you
typically get only about 15mpg.
Although electric vehicles are the desirable way to go, their strong
advocates nearly always fail to take account of several important
factors, which include (a) the environmental damage created in obtaining
the materials for the battery, (b) supplying sufficient public charging
points, (c) for domestic charging, getting a connection from the house
to the vehicle (which will frequently will be difficult or impossible),
(d) getting enough electricity from the power sources to the charging
points, (e) generating enough electricity in the first place, and (f)
disposal and recycling of worn out batteries.
As for the target for ceasing production of all new petrol/diesel/hybrid
cars by 2135, it seems to me that this will create a progressively
thriving market in used conventional vehicles. By 2050 or 55, there will
be a vast amount of old potential bangers on the road. Even if they have
been well-looked-after, many will probably no longer be capable of
meeting their original standards for polluting emissions.
