Assigning Blame for the Blackouts in Texas

By Planning Engineer

The story from some media sources is that frozen wind turbines are responsible for the power shortfalls in Texas. Other media sources emphasize that fossil fuel resources should shoulder the blame because they have large cold induced outages as well and also some natural gas plants could not obtain fuel.

Extreme cold should be expected to cause significant outages of both renewable and fossil fuel based resources. Why would anyone expect that sufficient amounts of natural gas would be available and deliverable to supply much needed generation? Considering the extreme cold, nothing particularly surprising is happening within any resource class in Texas. The technologies and their performance were well within the expected bounds of what could have been foreseen for such weather conditions. While some degradation should be expected, what is happening in Texas is a departure from what they should be experiencing. Who or what then is responsible for the shocking consequences produced by Texas’s run in with this recent bout of extreme cold?

Reassessing the RCPs

by Kevin Murphy

A response to: “Is RCP8.5 an impossible scenario?”. This post demonstrates that RCP8.5 is so highly improbable that it should be dismissed from consideration, and thereby draws into question the validity of RCP8.5-based assertions such as those made in the Fourth National Climate Assessment from the U.S. Global Change Research Program.

The cost of displacing fossil fuels: some evidence from Texas

by Peter Hartley

Although technological progress can alter the relative costs of different energy sources, depletion inevitably must raise the costs of fossil fuels leading to their displacement by alternative energy sources. What energy technology will likely be used when fossil fuels are no longer dominant? More importantly, what will be the cost of that alternative “backstop” energy supply?

Trying to Make Sense of Musk Love and Solar Hype

By Planning Engineer

Considerable efforts are being undertaken to restore power in Puerto Rico. Most coverage has been pessimistic focusing on challenging logistics and contentious issues with very little upbeat coverage on progress so far. There is one major exception to this trend, the efforts of Elon Musk and Tesla have enjoyed glowing coverage.

Electricity in Texas. Part II: the cost of a 100% renewable grid

by Peter Davies

While onshore wind generation has been relatively inexpensive for some time, solar PV and lithium ion battery storage costs have recently shown dramatic reductions. So can Texas, with excellent onshore wind and solar resources, be powered economically entirely by renewables in the 2030-40 time frame? This article brings together the available public material to estimate the cost.
