Quotesaid Aneeqa Khan, a research fellow in nuclear fusion at the University of Manchester. "Only if fusion power plants produce significant amounts of electricity later in the century will they help keep our carbon emissions down – and that will become crucial in the fight against climate change."
No, the added electricity will only make remaining fossil fuels be used faster. Collapse is intensified with each delay. You don't fight energy use by more energy use. Without restrictions adding more of one kind will increase use of all kinds.
I don't care what a research fellow in nuclear fusion needs to think to get through his day. If it helps him do his job, fine. The effect of using fusion is beyond his bailiwick. I give him his simple substitution.
