Ok, i've given you a bunch of studies showing 100% renewables in the grid is possible. I can add many more, but would you read them?
You are still telling me it's not possible. Can you do something to underline your point? An argument perhaps, cite a study, something like that?
Maybe I can try also?
The way I see it is that they are just studies, the like we've all been reading since the nineties. These studies are often published by interest groups (although definitively not all), they have been challenged and there are other studies out there also. Because I don't have the knowledge and credentials to debunk or approve them, I can only look what's happening in the real world.
We hear a lot how 100% renewable economy is feasible and how renewables are nowadays the cheapest form of generation. We see two or three digit global growth figures for renewables. Yet emissions are growing every year. How can that be? Something ain't right here.
Non-hydro renewables are intermittent. To cover the downtime we need overcapacity, extensive power grids, grid-scale storage, fossil fuel back up power and/or flexible demand. These all add costs. Using FF backup is no longer carbon free. Storage + adjusting demand aren't available in commercial grid-scale solutions, no matter what the studies say.
My claim is that when taking all the additional costs into account renewables are no longer cheap but extremely expensive. German energiewende is a case in point. With a cost so prohibitive that only a handful of countries in the world would be able to afford it, Germany has been able to generate less than 50% of it electricity (not primary energy) with non-hydro renewables. As a consequence Germany is failing its emissiong goals.
Historically emissions have been falling by post-oil crisis nuclear construction for example in France and Sweden, economic collapse/recession for example former Soviet Union and the financial crisis, switching coal to gas with several examples around the world.
I'd like to believe it is also possible to reduce emissions by pricing carbon politically/fiscally, unfortunately the trumps and bolsonaros don't give me much hope we will be able to try this option anytime soon. I voted 2040-49 because I think by then the inevitable climate related economic stress will lead to emission peak and subsequent reduction. I'd be very happy to be proven wrong.
