From the bottom of the page:

> TL;DR: we can delete most of the emissions of the developed world today by switching heating & car and truck transport to electrical - if we make sure we generate all electricity with near-zero emissions. Just building more renewable generation won't solve it though, as you still need to make sure it covers all consumption everywhere. This map intends to show why that's a complicated problem, and why we should also be smart about where we build renewable generation so that most of the generated energy can also be used and not thrown away because the grid can't handle it.

This is what I wonder about when I drive through West Texas and see massive wind farms in the middle of nowhere.

Stats on wind and solar curtailment on the Texas grid - https://www.eia.gov/todayinenergy/detail.php?id=57100

"In 2022, the Electric Reliability Council of Texas (ERCOT), the grid manager for most of Texas, curtailed 5% of its total available wind generation and 9% of total available utility-scale solar generation. By 2035, however, we project wind curtailments in ERCOT could increase to 13% of total available wind generation, and solar curtailments could reach 19%."
