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 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 […]

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 […]

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 […]

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 […]

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 […]

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 […]
