Love that you try to avoid the issue of cost. Yeah, in the land of infinite money and resources you can do anything.

In the real world the energy crisis was a cost crisis. But you seem to no care the slightest about massively increasing the ratepayers bills and by that creating a new self made energy crisis. This time fueled by nuclear subsidies.

So you skipped the first two studies. I suppose because you found nothing to complain about in them. Good to know.

Then you go on a meta-analysis on the entire field and demand them to produce a TWH figure for some energy system you can't even specify.

You truly are grasping for the straws.

Here's the quote you missed:

> Much of the resistance towards 100% RE systems in the literature seems to come from the a-priori assumption that an energy system based on solar and wind is impossible since these energy sources are variable. Critics of 100% RE systems like to contrast solar and wind with ’firm’ energy sources like nuclear and fossil fuels (often combined with CCS) that bring their own storage. This is the key point made in some already mentioned reactions, such as those by Clack et al. [225], Trainer [226], Heard et al. [227] Jenkins et al. [228], and Caldeira et al. [275], [276]. However, while it is true that keeping a system with variable sources stable is more complex, a range of strategies can be employed that are often ignored or underutilized in critical studies: oversizing solar and wind capacities; strengthening interconnections [68], [82], [132], [143], [277], [278]; demand response [279], [172], e.g. smart electric vehicles charging using delayed charging or delivering energy back to the electricity grid via vehicle-to-grid [181], [280]– [282]; storage [40]– [43], [46], [83], [140], [142], such as stationary batteries; sector coupling [16], [39], [90]– [92], [97], [132], [216], e.g. optimizing the interaction between electricity, heat, transport, and industry; power-to-X [39], [106], [134], [176], e.g. producing hydrogen at moments when there is abundant energy; et cetera. Using all these strategies effectively to mitigate variability is where much of the cutting-edge development of 100% RE scenarios takes place.

> With every iteration in the research and with every technological breakthrough in these areas, 100% RE systems become increasingly viable. Even former critics must admit that adding e-fuels through PtX makes 100% RE possible at costs similar to fossil fuels. These critics are still questioning whether 100% RE is the cheapest solution but no longer claim it would be unfeasible or prohibitively expensive. Variability, especially short term, has many mitigation options, and energy system studies are increasingly capturing these in their 100% RE scenarios.

With the conclusion based on the meta-analysis:

> The main conclusion of the vast majority of 100% renewable energy systems studies is that such systems can power all energy in all regions of the world at low cost. As such, we do not need to rely on fossil fuels in the future. In the early 2020s, the consensus has increasingly become that solar PV and wind power will dominate the future energy system and new research increasingly shows that 100% renewable energy systems are not only feasible but also cost effective. This gives us the key to a sustainable civilization and the long-lasting prosperity of humankind.

Since the study was released in mid 2022 has it become easier to harder to create 100% renewable energy systems? Easier.
