Yes, yes. That's exactly what I was getting at, thank you for putting it so well.
I listened to something on YouTube the other day that suggested that electricity could be almost cost-free in the future once durable installations to generate it were installed. Obviously there will be some maintenance costs, but if the solar panels and the wind and wave turbines are installed and generating away, the ongoing costs will be very small. Certainly compared to the costs of ongoing fossil fuel extraction.
I wonder how true this is? I don't wonder why some people are opposed to it.
