The Trendline is not good

Going on 4 years ago I wrote two blog posts outlining what I thought were the best case and worst case scenarios for the five years from 2013-2018 in terms of developments in renewable energy. Given recent events in the United States I thought it might be interesting to revisit those posts and see where […]

The $US 134 Trillion, 100 Year Challenge

As anyone who has read some of my blog posts knows I do not believe that we should be basing our transition to a sustainable energy environment on the need to moderate climate change. I’m not convinced that eliminating the burning of hydro-carbons altogether would make a huge difference to what our planet is doing. […]

Hydrokinetics – The Renewable “Silver Bullet”

In searching for technologies that can aid in the transition to a low carbon environment the following characteristics would define the ideal new energy source; Characteristic Wind PV Solar Large Hydro Hydro-kinetics Geo-thermal Can generate electricity without any fuel Yes Yes Yes Yes Yes Reliable at peak demand times including winters in middle latitudes No No […]

The Revolution is Being Televised

This post isn’t directly related to alternate energy but discusses what I believe is a serious issue with the way that we govern ourselves. Problems translating the “will of the people” into political action will impact all policy decisions including those related to attaining a sustainable energy environment. Political leaders, captains of industry, and ordinary […]

How Quickly will the Electric Vehicle Revolution Come?

In a previous posting I stated my belief that EV's will continue to make up an ever-increasing fraction of the vehicle fleet worldwide.  However, the pace at which the transition will happen depends upon many factors.  I now believe it will probably take an extended period of time – decades perhaps – to move a […]

Where are Natural Gas prices headed?

A lot of decisions about how the electricity industry will evolve depend upon the future of Natural Gas prices. As prices hit historic lows in the last 2 years drilling activity dried up. Recent “tight gas” and “shale gas” reserve additions experience rapid declines. To me the signals are for significant price increases in the […]

Germany at the Crossroads

For more than 10 years Germany has been the poster child for the development of renewable energy sources – principally Photo-Voltaic (PV) solar and wind. The Germans have stoically endured ever-increasing electricity rates that cannot do anything but continue to go up because of guaranteed Feed-In-Tariffs (FITs) for systems being installed each month. They have […]
