The Coming Age of the Smart Green City Building

Date: Oct. 17, 2016

What kind of buildings will be in the smart cities of tomorrow? While the cities of the future will still be home to older historical and other buildings that are not energy-efficient good citizens of the power grid, the move will increasingly be to smart green buildings.

Will Hydrogen Be the Savior of Overloaded Microgrids?

Date: Oct. 17, 2016

What sources of power can be counted on to back up microgrids when power from utilities runs low? We all think first about solar, batteries, wind, hydro and geothermal. But what about hydrogen? Maybe we should be thinking about that too.

Grid Alternatives on Tribal Communities

Date: Oct. 11, 2016 –

In years past, many tribal lands were too remote to have access to reliable electricity. Many relied on gas and diesel-powered generators. That is changing, thanks in large part to the Department of Energy’s Tribal Energy Development grant program that is administered by the U.S. Department of the Interior.

American Cities and Highways Counted on LED Lighting. Were They Wrong?

Date: Oct. 4, 2016

Thanks to their long life and low power consumption, light emitting diodes (LEDs) have become the lighting source of choice on about 13% off all American streets and highways. That might not be such a wise choice, according to “Human and Environmental Effects of Light Emitting Diode (LED) Community Lighting,” a report issued in June by the American Medical Association. 

Columbus OH Thinks that Mass Transit Is Going Away

Date: Oct. 4, 2016

City planners in Columbus, OH had some thinking to do in June when their city won the U.S. Department of Transportation’s Smart City Challenge. The Challenge gave Columbus $40 million to invest in transit. Where would that grant money go?

The Role of Passive Radiation in Smart Grid Design

Smart City

Date: Sept. 27, 2016

The smart cities of tomorrow will be increasingly powered and heated by the sun. But not all solar-generated power will come from solar panels located on buildings or in fields nearby. A lot of the energy will be passively collected by the buildings themselves. And thanks to increasingly intelligent designs, smart self-heating buildings are posed to have a bigger impact on the design of smart grids.

The World Starts to Light Up with Battery Power

Date: Sept. 21, 2016

Lots has been happening in the world of batteries since July, when Tesla opened its $5 billion Gigafactory in the Nevada desert. Battery production is ramping up there in two distinct product areas: batteries for use in Tesla automobiles and sleek-looking new Powerwall batteries for use in buildings. According to Tesla, each Powerwall battery can store up to 6.4 kilowatts, enough to provide overnight power to most homes.
