[attachment=4119 Wrote:stuartu pid='17555' dateline='1539244530']In addition to the points Simon raises, a further question that interests me is, will the infrastructure to supply enough power be in place?Ah don't worry the authorities have thought of what happens when there is no wind, STOR (Short Term Operating Reserve), which appears to be a well kept secret. Basically if you have some spare money, you build a diesel powerstation using containerised truck engine gen sets and give the keys to the National grid who switch them on as required.
We have been known to get power cuts if everyone switches on their electric ovens at the same time. It's all very well having 68% of your electricity provided from renewable sources but what fraction of the potential demand is that when everyone who currently has an ICE powered car is charging up their electric runabout? However clever the battery technology, you still need enough energy to feed it.
How long does it take to build a power station? How many more will we need?
Now may be the only time an electric vehicle is a practical proposition, while there aren't too many of them.
Regards,
Stuart
