What We Don’t Know Can Hurt Us

As Americans cranked up their air conditioners to gain relief from sweltering mid-July heat, the grid called for all-hands-on-deck to keep the power flowing. Soaring electricity demand was met by every power plant utilities and grid operators could throw at the challenge. Thankfully, for most Americans, the lights and the AC were there when they […]

Trillions with a “T”

According to new analysis from Wood Mackenzie, transitioning to an all renewables grid in the U.S. by 2030 would cost roughly $4.5 trillion. Remarkably, that cost – estimated at about $35,000 per household – does not account for the costs of prematurely closing hundreds of existing power plants, the inevitable supply chain bottlenecks that would […]

Driving Up the Cost of Power for Consumers

Making an apples to apples comparison of new weather-dependent renewables against existing coal or nuclear power plants cannot be done – at least not with our existing tools. Not only are you trying to compare one source of variable power to dispatchable, baseload generation that’s available 24-7, but you’re also attempting to compare a facility […]

The Real Energy Story in the U.K.

From the tone of the coverage announcing that the U.K. has gone more than 10 days without generating any electricity using coal, one would think Britain had singlehandedly turned the tide against rising global emissions. Renewable boosters and climate hawks have fallen over themselves in praise of this “accomplishment.” But what this fawning coverage has […]

Affordability and Reliability First

In a nation that holds polarizing views on nearly everything, it’s telling when a poll returns decisive, bipartisan consensus on an issue. That’s precisely the case in a new poll from Morning Consult which asked Americans how they believe the current transformation of the grid should be approached. Asked if they would like to transition […]

Mandating Higher Electricity Prices

The suspicion for some time has been that renewable portfolio standards are an incredibly costly and inefficient energy policy. Yet, they have grown in popularity and ambition with 29 states and the District of Columbia employing these mandates and policymakers from time to time flirting with a national standard. Suspicion has now been replaced by […]

Batteries: Great Promise, Even Greater Hype

Lithium-ion batteries are everywhere. From our smartphones, computers and tablets to electric vehicles, we are in the midst of a battery revolution. But for all the promise of batteries, there are limitations. There are physics problems that dictate how batteries can be used, or should be used, that need to inform our energy policy. Unfortunately, […]

New Report Reaffirms Electricity Markets Aren’t Adequately Valuing Reliability

A new study being pushed by renewables advocates deserves note – but not for the reason its backers claim. It is noteworthy in that it is the perfect example of just how dysfunctional our electricity markets actually are and how uninformed the energy debate has become. The study, titled “The Coal Cost Crossover,” suggests that […]

A “Very Scary” Situation in Texas

Texas got a taste of cooler than expected weather this week and it sent shockwaves across the state’s electricity market. The Lone Star State learned a valuable lesson about putting too much faith in intermittent renewables. Temperatures dipped Monday morning, increasing heating demand, and that cooler weather was accompanied by calmer than expected winds. Calm […]

A Solution in Search of a Problem

It’s not uncommon to hear calls for rebuilding and transforming the electricity grid. In fact, renewable energy boosters say transforming the grid is an imperative if the nation is to reach their goal of 100 percent wind and solar power. But this call for transformation exposes some of the underlying problems with the proposed wind […]
