This is within the context of making reforms to cybersecurity efforts. “Inverter-based resources” means energy sources like solar panels and wind turbines that generate direct current (DC) electricity, but must be converted to alternating current (AC) energy to be compatible with the existing electrical grid. Inverter-based systems, while essential for the integration of renewables, introduce certain challenges because they don’t inherently provide the same type of synchronous stability (like frequency regulation) that traditional generators do.

Are renewables a “threat to the grid”? It’s true that improperly managed, they don’t provide inertia in the same way and are therefore less stable in the absence of proper controllers. Traditional power plants have large, rotating turbines that provide inertia, which helps stabilize the grid by automatically maintaining the frequency (usually 60Hz in the U.S.). Inverters can offer synthetic inertia and other forms of frequency support, but they require advanced control systems and careful grid integration. So it’s possible and manageable, a fact that McNamee does not admit.

Renewable energy isn’t inherently a threat, but the grid does need to be modernized to accommodate a higher share of renewables. This includes better energy storage solutions (like batteries), improved grid infrastructure, and demand response systems that can adjust electricity use based on availability. Increasing renewable energy sources diversifies the energy mix, reducing reliance on fossil fuels and increasing energy security.

While renewable resources do pose technical challenges (due to their intermittency and the way they interact with the grid), framing them as a “threat” overlooks the potential for grid modernization, technological advances, and the broader benefits of transitioning to clean energy. It’s baseless fearmongering on McNamee’s part.
