Lewis, that and many other suitable systems can be used.
But the problem is not climate change or global warming, it is the pressure applied to various govs around the world by those who will gain from any change.
The electric vehicle is one such venture, Elon Musk and a few others will make a killing from this.
We have an ex PM who has invested millions in solar power, he will make a lot from this.
WE now have the smart electric meter and also a water one soon to be rolled out.
The electric was developed here in Oz but no gov was interested so he took it to UKI.
They took it on so the gov here then decided to use it.
We are told that with this meter we can control our power usage, problem is no one understands how to use it, but the power companies can now charge you by the half hour during peak use and no cost for meter readers.
This is how thing work, not what you know but who.
