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 […]

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 […]

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 […]

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. […]

This morning I was shocked to read a report by the UK’s Renewable Energy Association which finds that the UK met 19.2% of its electricity demand with renewable energy in 2014. This is the result of a 20% increase in renewable energy output over the previous year, and evidence that the UK is joining the […]
