Shared Resources and Community Energy Storage

|

In today’s sharing economy, the concept of communal energy resources, collective energy purchasing, and community microgrids, the emergence of community energy storage (CES) is only logical. I learned recently that the concept involves the modular use of batteries at the neighborhood level to help integrate distributed energy resources and manage  … Read More

Geoffrey Moore’s book, Crossing the Chasm, speaks to the moment when disruptive technologies make the leap from early adopter to early majority customers, signaling the maturity of a technology and its acceptance as a mainstream solution. This, I think, is where we stand today in the public transit arena with  … Read More

Although lithium-ion batteries are the most commonly used energy storage technology—powering cell phones, cars, and the electrical grid—the technology has limitations. The lifespan of lithium-ion batteries is relatively short. Furthermore, they can be challenging to recycle. Researchers today are working to develop new chemistries that will provide a non-toxic, non-corrosive  … Read More

As anyone who has contemplated getting a helicopter rating knows, FAA’s requirements are somewhere between ridiculous and sublime.

With no rating at all it will take you close to 45 hours of dual instruction and 20 hours of solo practice flights before you are ready for your checkride. Even if you  … Read More

There is an old military saying that “Amateurs talk about tactics, professionals talk about logistics.” Nowhere is this more true than in the fuel and energy requirements of a military formation deployed in a combat theater.  … Read More

Renewable Energy for Onsite Power Generation

Renewable Energy for Onsite Power Generation

|

Although every situation is unique, and it’s difficult to generalize, Barry Worthington, executive director of the US Energy Association (USEA) in Washington, DC, says progress in renewable energy over the last 10 years has been phenomenal as systems become more efficient. Nevertheless, use of renewable energy for onsite power generation  … Read More

Why Microgrids Are Inevitable

Why Microgrids Are Inevitable

The fledgling electric utility companies that emerged after Thomas Edison opened his small Pearl Street, New York City, NY, power station in 1882 originally focused on distributed energy generation (DEG) operating within a microgrid. Edison envisioned that the electric utility industry would involve small firms generating direct current (DC) power  … Read More
