The Jacobson debate: Distractions, detours and the Energy Transition

About six weeks ago, a think tank in London, Climate Policy Initiative, released a study on integrating high levels of renewable energy. It wasn’t the first such study; many others have been done, including a series by the U.S. DOE’s National Renewable Energy Laboratory that looked at penetrations up to 90% renewable energy on U.S. […]

Vision is needed: a response to Julian Spector

Vision is needed: a response to Julian Spector Last week I found myself in a social media spat about the credibility of the main source cited in an article written by Julian Spector on Greentech Media. The central theme of the article is a stance against the 100% renewable energy mandate proposed by California Senate […]

Energy Transition update: 2016

My readers will forgive that a rather lengthy absence from this blog has meant that I have not updated my global renewable energy statistics yet with numbers for the full year 2015, most of which have been out for a few months. The numbers which are available maintain earlier trends, namely a stagnation in Western […]

Why I am not covering the Clean Power Plan lawsuit

If you follow mainstream climate and energy reporting, you would think that as a renewable energy reporter, I would be all over the arguments being made this week in the legal challenge to the Obama Administration’s Clean Power Plan (CPP) by the criminally deluded leaders of 27 states and whatever assorted coal industry super villains […]

Things I was wrong about

The delay in my posting is sufficient enough that there isn’t even much to say about it. However, this period of time has further established certain trends which to observers more savvy than I were obvious years ago, and an update to the perspectives in my previous posts is sorely needed. We who observe and […]

Postcard from the future: Solar and the Energy Transition in Kaua’i

Hawaii has been called a “postcard from the future” due to the high levels of renewable energy being deployed and technical work that is being done to accommodate this. But even for Hawaii the amount of solar that has been put online in the island of Kaua’i is impressive, as are the technical challenges being […]

Very high levels of renewable electricity: Geography and diversity in cat-skinning methods

The last three posts on this blog have all dealt with the feasibility of reaching very high levels (80% or more) renewable energy in our electricity grids. Specifically, these posts were responses to articles dismissing the possibility doing this quickly, whose arguments I did not feel were well supported by facts and existing research. I […]

Flawed arguments: A critique of “Upper Limit to Variable Renewable Energy”

My readers will pardon that I am, for the third time in a row, writing a piece inspired by a post by David Roberts of Vox. Unlike most of the media David Roberts is writing intelligent articles about what I consider to be the most critical issue of our time, the global transition to renewable […]

The Jacobson Plan: 100% renewable energy in the United States

This week a team led by Stanford Professor of Civil and Environmental Engineering Mark Jacobson presented the latest results of its work on the technical and economic feasibility of moving the United States to 100% renewable energy by 2050. This includes state-by-state assessments and covers all forms of energy: Electricity, transit, heat and industry. Their […]

Just because you don’t see it doesn’t mean it’s not there: A response to “The awful truth about Climate Change”

My readers will pardon that it has taken me a full week to respond fully to David Roberts’ post in Vox, “The Awful Truth in Climate Change”. I’ve been busy as usual with other matters this last week, and frankly it took me a little while to fully articulate what I have to say here. […]
