Green Building

 

A blooming industry, green building is rising with greater public demand, legislative focus, and code and standard mandates. With programs like Leadership in Energy and Environmental Design (LEED) becoming more popular, contractors are finding new building processes and technologies to be more efficient and environmentally minded. The below articles dive into alternative energies, energy efficiency, the smart grid, and more and include editorial from our annual special issue on the subject.

Talk to folks in the electric vehicle (EV) industry about commercial charging opportunities, and there is a very good chance you’ll hear that old which-came-first/chicken-or-egg metaphor applied to the market’s potential.

Separated from the U.S. mainland’s electric supply by an ocean, Hawaii is working toward a goal mandated by Hawaii’s Renewable Portfolio Standard (RPS), which requires 40 percent of the state’s electricity to be derived from clean-energy sources by 2030.


You could call it utility-scale renewables 3.0. 
The previous two phases focused on getting large solar arrays and wind farms up and running (1.0) and then boosting their output (2.0). Today, developers are looking beyond just adding more rows of panels or bigger turbines to their plans.

It’s no secret that the global economy, available energy supply and the balance-sheet status of the worldwide electrical supply-chain industry are never going to return to the levels they reached at the end of the 20th century. There is no optimistic rebound coming.
