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.

Is RCP8.5 an impossible scenario?

by Judith Curry

In considering ‘worst case’ climate change impacts, we first need to assess the realistic worst case for global carbon emissions.

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.

Vehicular decarbonisation – two new technologies to watch

by Rud Istvan

This post addresses issues related to  ‘vehicular decarbonization’. It is  an energy storage insider’s narrative of how tough a slog developing some of the requisite applied science technologies has been over the past decades. It is a saga of research twists and turns, abject failures, near misses, and ‘before its time’ inventions.

Energy and Environment on the “Garden Island”

by Planning Engineer

·        Countering the presumption that renewables are always the environmentally preferable alternative, this column suggests that serious consideration should be given to examining if for the short term, fossil fuel might be the “environmentally correct” near term alternative for Kauai.
