Are you saying you don't believe in modelling based on historica data ?
How do you think anything gets designed these days ? Do you think they just make it up ?
Or do you think they look at historical ( and live data ) in order to design infrastructure ? Roads , dams , hospitals , powerstations , oil fields , gas fields etc .
All done via scientific studies and modelling .
Welcome to 2018 .
Btw . Still waiting for you to post the reasons why power prices are so high and how new coal power stations will make power cheaper . Look forward to you posting a breakdown of the numbers to support your argument .
