I've been led to believe that we have enough energy producing capabilities on average but not enough to cope with the peaks. It is this statement that i find interesting with regards to the future.
I know the general view recently has been that electric vehicles can't go so far without needing a re-charge, but if you look at the new generation EV's such as the Jaguar ipace with a range of around 320 miles and can get a 150 mile re-charge in around 15 minutes things start to look a bit different.
I always wondered what would happen when everybody comes home and plugs in at tea time, but this same Jaguar could run several houses. So imagine a situation where EV's are covering the surge from say 5pm to 9pm and 7am to 9am but are receiving power at the other times it them starts the level all the peaks and troughs in power production.
I have also been told that there will be a scheme set up to utilize any used EV batteries. As mentioned about the Jaguar, i think it has an eight year warranty on the battery but should last a lot longer, the problem being it's efficiency will drop with time and use. So when it is no longer viable as a car battery it would then be put to use to store energy at local sources.
For example a friend has solar panels but during the day power has to go to the grid as he is not using it, but at night he has to draw from the grid as he has no production. If he had batteries he could store his own energy during the day to use later. I also read an article where EV's would have free parking and charging at railway stations as the cars would be helping to provide energy for the trains as they leave but would accept energy as the trains regenerate when slowing into the station. Again levelling the peaks in demand.
Where do others think we will be in say 5 years time?
With the push for electric cars and the increasing cost involved entering cities due to pollution i don't think we have many options.
