Re: Solar Panels
Here is a simplified explanation for the UK. It turns out that most charging (approaching 90%) of electric cars is done at night, so for a very long time to come you can use the gap between day and night demand to charge these vehicles. This yields about 10-12GW of capacity over about 7-8 hours, conservatively 80GWh per day. At 250Wh per mile that allows you to charge say 12 million electric vehicles without needing extra grid capacity. The full UK car fleet is about 32 million vehicles, averaging 7,900 miles per year by the way. Of course you will need to burn extra fossil fuel but that is more than offset by the diesel and petrol you no longer need. More to the point this will clean up our city air considerably.
