The energy transition calls for more electrification. As transportation, heating, industry, and now power demand from data centers all crowd the interconnection queues, the US needs more transmission than it has built in generations. Even energy transition skeptics can agree on the wires.
But agreement on the need for more transmission has never been enough to get lines up and running. In 2019, journalist Russell Gold joined us to tell the story of Michael Skelly, who tried harder than anyone. His company, Clean Line Energy, spent a decade developing five major transmission lines to move wind power from the Midwest to the cities that needed it. His flagship line, the 700-mile Plains & Eastern, was fully permitted and offered the Tennessee Valley Authority twenty years of wind power at $18.50 per megawatt-hour, a price even the cheapest coal can't match. But economics aside, TVA walked away and not one of the five lines got built. Gold's book Superpower explains why engineering or economics weren't able to overcome the rules written state by state that build "regulatory moats" around the incumbents and keep the outsiders out.
Seven years since then, and those moats are where the race to tackle growing power demand is backing up. Recently ERCOT froze approvals of new data-center connections while the state audits an interconnection queue that has swelled to roughly 474 gigawatts of requested power capacity, more than five times the all-time peak power demand on the Texas grid. In Washington, FERC ordered the six regional grid operators it oversees to explain where the transmission for loads like that will come from. The specific fights are new but the overall mechanism is the one Russell Gold mapped with our host Chris Nelder back in Episode #98.
Since then, Grain Belt Express, the line Skelly had to sell on the way down, has grown into an $11 billion, 800-mile project with $1.7 billion in construction contracts signed. And Skelly has a new company working on the first large-scale connection between America's two big grids, a step toward the concept of Superpower that would tie the country's balkanized regional grids into one that could more readily support the energy transition's future.

Over the summer, the IEA projected that carbon emissions from the world's power sector are on track for a new record in 2026. Electricity demand is expected to grow 20% faster than it did a year ago, and this year's gas shock has pushed some countries to use more coal.
When we first created the Energy Transition Show in 2015, solar generated about 250 terawatt hours worldwide. That was roughly as much electricity as California used the same year. A decade later, as the energy transition moved ahead, solar generates more than ten times as much, matching the European Union's total electricity demand.
Transportation continues to electrify, as a quarter of the world's new car market in 2025 was electric, both battery and plug-in hybrids. And this area of the energy transition is already showing up in metrics that matter for the climate. Recent data shows that running a battery electric car on Europe's grid cuts lifetime emissions by more than 70% against a comparable combustion car.
Millions of Americans are sweltering under heat domes this summer, with temperatures soaring to record highs when weather systems stall. The grid feels the strain of these events too.
The Statistical Review of World Energy 2026 is out, offering the first complete look at global energy data for 2025. The report's 75th edition, now presented in partnership with the energy think tank Ember, reveals a year in which demand for every form of energy hit a new record high.
