The Two Grids: Why Policy is Breaking Physics - Meredith Angwin Stops by the Energy News Beat Podcast

Welcome back to the Energy Newsbeat podcast. Today, we’re diving deep into one of the most critical—and misunderstood—issues facing America’s energy future. Most people think the grid is just the wires and power plants they see.

But what if I told you two grids are operating at the same time, and they’re increasingly working against each other? One is governed by the laws of physics. The other is governed by policy papers.

And right now, policy is winning—with dangerous consequences. Our guest today is Meredith Angwin, author of “Shorting the Grid” and what we call the national treasure of energy. She’s here to explain why your electricity bills are skyrocketing, why rolling blackouts are coming, and why the $10.3 trillion we’ve spent on wind and solar hasn’t made our grid more reliable—it’s made it more fragile.

If you care about keeping the lights on, affording your power bill, or understanding the real state of America’s energy infrastructure, you need to hear this conversation.

1. The Two Grids Concept

Meredith explains her theory that there are two distinct grids operating simultaneously:

The Physical Grid: The actual infrastructure you can see (transmission lines, substations) governed by immutable physics and laws

The Policy Grid: A set of regulations and policies (net metering, renewable portfolio standards, net-zero mandates, renewable energy certificates) that determine how the physical grid is paid for

The key insight is that policy decisions often ignore physical realities, creating conflicts between what regulations demand and what physics allows.
