The temperature is 100 degrees and we have no air conditioning, no running water, no telephone and no Internet. It’s been 60 hours since our household lost electricity because of the super derecho, a rare surprise storm that swept ten US states and the nation’s capital on June 29. (more…)
It’s easy to get the impression that technology game-changers happen in a near flash. And the stories of Facebook, Google, Microsoft and Apple leave us thinking that genius pops right out of the dorm room.
But in the energy industry it’s not that easy. The innovation we see today often stems from years of (more…)
The success record of smart grid renewables integration is a mixed bag, with European countries boldly plowing forward while many utilities in the United States exhibit what a former California state regulator called “electrotrophobia” – the fear of change linked to greater reliance upon intermittent renewable energy resources.

One of the most promising aspects of energy storage is that it’s used to make an existing system more efficient. If you think of the grid as the system, then energy storage can help make generation, transmission, distribution, and even customer energy use more efficient.
How many different systems are there? The grid is the (more…)
I have been reluctant to join the fray on what the recent Japanese disasters might mean to this or that issue. With active clients in Tokyo, these tragedies have had a personal effect, and my first thoughts have been for the personal well-being of these clients, their families, and their colleagues. So while the most important (more…)
Microgrids may be a hot topic among those forecasting key future trends shaping the world’s energy infrastructure, but few significant state-of-the-art commercial microgrids are actually up and running in North America, the world’s leading market for microgrids. One (more…)
Imperial County, tucked away in the southeastern corner of California, has long suffered from perennial unemployment rates exceeding 20 percent.
Yet Imperial County is also home to the “crown jewel” of all geothermal steam resources in the U.S., making it a prime spot to showcase how renewable energy can help spur the new green economy so enthusiastically touted by the Obama Administration.
Late December, the California Public Utilities Commission (CPUC) approved the construction of the $1.9 billion Sunrise PowerLink transmission line, which could send clean electricity from Imperial County to San Diego. However, the Center for Biological Diversity (CBD) petitioned the California Supreme Court last January to review this decision, citing San Diego Gas & Electric’s (SDG&E) refusal to guarantee that the transmission project would be reserved exclusively for renewable energy resources.
