We now live in an economy that can’t function without electricity – there are no substitutes for it. Our lifestyles depend on electricity to keep us comfortable and productive on a 24 x 7 basis.[read more]

Where's the Real Bottleneck for Natural Gas? Distribution

January 25, 2013 by Steve Skutnik

As a scientist and an unabashed nerd, I love data. Particularly, I love it when ready access to data reveals things that are surprising in the face of conventional wisdom. Despite record-low wholesale electricity prices there's been a slow but quite noticeable creep of wholesale natural gas prices upward to the range of $6/MMBtu.[read more]

The devastating earthquake and tsunami in northeastern Japan offer horrifying visuals of a geologic worst case scenario.   It may also deliver a worst case disaster scenario for their national electrical system as some nuclear plants are beyond repair.  According to the Department of Energy’s global statistics,  in...[read more]

Do We Need a Smart Grid, A Strong Grid, Or Less Grid?

January 19, 2010 by Rod Adams

One of the reasons that I am a strong advocate of smaller nuclear energy plants is that I resist the notion of the inevitability of greater interconnectedness and dependence. I like systems that have firewalls, circuit breakers, and air gaps to ensure that a failure in one location can be isolated. I do not like tightly integrated...[read more]
