Winter Freeze Exposes Solar and Wind’s Reliability Gap
Late January's winter weather was a perfect litmus test for purported replacements of fossil fuels. If a type of “power” or “capacity” cannot reliably contribute to preventing Americans from freezing to death during a week of nationwide cold weather, whatever else it is doing it is absolutely not replacing fossil fuels. Solar and wind failed that test.

Closing Fossil Plants Drives Winter Grid Strain, Price Spikes
Had we not shut down so many coal plants and suppressed so many pipelines and prevented so many gas plants, this winter's electricity demand could have been easily and cheaply met. Instead, it strained grids, spiked power prices, and spiked heating...

Solar and Wind Save Fuel for Reliable Power
If solar and wind are not replacements for fossil fuel power, what are they? After all, they are doing something—witness charts showing large amounts of “generation” in a day or the largest growth in “generation” and “capacity” over time. That “something” is...

Solar and Wind Are Intermittent, Not Reliable Power Sources
All energy discussions, analyses, and policy-making must totally stop treating solar and wind as reliable power sources and instead treat them as intermittent fuel-savers.

AI Demand Pushes Tech Giants Toward Real Nuclear Power
Tech giants spent years pretending to be "100% renewable," i.e. powered mostly by intermittent solar and wind. Now that they need large amounts of energy to power AI, they're not pretending any longer. Case in point: Meta's major new investments in nuclear...

Renewables Need Fossil Backup, Not Standalone Power
When you see that a new solar and wind project is said to “power” some large number of homes or factories or data centers—know that the solar and wind are “powering” nothing by themselves, since they are entirely dependent on...

US Solar and Wind Spending Yields No Economic Value
Even though solar and wind theoretically have value as intermittent fuel-savers, the hundreds of billions spent on them in the US so far have mostly amounted to burning other people’s money and have created no economic value whatsoever.

Discussing Good Energy Policy on a Non‑Partisan Podcast
I’ve been seeking out more non-partisan forums to share my views. Here's a non-partisan podcast I went on recently to give an overview of what I think good energy policy looks like. https://t.co/D2c1X4Z1Jj

Winter Storms Expose Solar and Wind’s Reliability Limits
When winter storms arrive, solar and wind frequently generate less than 10% of their supposed "capacity." If we tried to truly rely on solar and wind to the point of shutting down more fossil fuel plants, Americans would have routine blackouts. Do...

Solar and Wind Aren't Cost‑competitive; They Add to Power Costs
We often hear the claim that intermittent solar and wind are cost-competitive with reliable sources of electricity. This is an accounting fraud. The cost of solar and wind is paid on top of the cost of an on-demand power source, not instead...

Solar Power Unreliable Even in Sun‑Rich Regions
No matter how sunny a region it is deployed in, solar is not a reliable source of power. Even in sun-drenched Arizona, a series of three low-pressure systems wiped out most of the state's solar energy for 6 days in January...

Anti‑fossil Policies Raise Electricity Costs Despite Cheap Gas
The number one source of electricity on the grid is natural gas. Its price has fallen since 2010. Meanwhile, electricity prices have gone up significantly. This shouldn't happen. This is the direct result of anti-fossil-fuel policies based on the dangerous and false belief that...

Winter Storm Leaves Solar Power Completely Ineffective
As badly as wind performed during recent winter weather, solar performed far, far worse. As often happens during winter storms, solar was mostly or totally useless during the times of highest demand (evening and early morning). In Florida, which was hit later...
