Economic and emissions impacts of electric vehicles

President Obama during his 2011 State of the Union address stated that we should have one million electric vehicles (EV) in the United States by 2015. The benefits of that would be to to reduce our dependence on foreign oil and to reduce emissions. These are worthy goals. This article will take look at the economic impact of using electric cars, their emissions, and their impact on the electric grid.

Nuclear energy is a disruptively cheap and simple way to boil water

For the majority of human history, people used their own muscles to provide almost all of the work required for survival and development. A thin slice of humanity achieved a moderate amount of personal comfort and leisure because they were able, often through an accident of birth, to control a portion of the daily work output of hundreds to thousands of their fellow humans. The only sources of work-in the engineering sense-that were not either human or animal muscle came from capturing falling water or intermittently by capturing the breezes through devices like cloth sails or wind mills.

Thoughts on President Obama’s Clean Energy Standard proposal

In his State of the Union speech on January 25, President Barack Obama advocated a Clean Energy Standard that includes natural gas as well as renewables, nuclear and "clean coal." In my previous post on Clean Energy Standards, I said that if the standard were expanded to include natural gas generation, then the required clean energy percentage would have to be increased substantially in order for the policy to remain meaningful, particularly if gas is given "full credit" (i.e., is treated no differently than non-emitting generation).

The oil spill: Nuclear, take note

A few months ago, I had the honor of leading a class of future engineering leaders at Iowa State University. The dean, Dr. Jonathan Wickert, occasionally asks alums and others who have done interesting things with their engineering degrees to come in and lead the class in a case study. Events in the Gulf of Mexico that started in April 2010 with the Macondo oil spill provided an excellent opportunity to talk about crisis management and communications, with the added benefit of current technology relevance. This is an area that the nuclear industry also needs to study and understand.

We always knew nuclear was green!

This year's North American - Young Generation in Nuclear (NA-YGN) continental conference was held in May and was themed "Leading the Change: Go Green." Participants learned that the future of electricity production in the United States would be heavily influenced by the desire to combat global warming. This desire is starting a national debate on how the country should select technologies for new electricity production facilities.
