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.

Once upon a time, many solar-enthusiast homeowners saw their rooftop photovoltaic (PV) panels as investments in a greener future, not as contributors to their own household budgets.

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.


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.

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.

Shining The Light On Super Solar Efficiency

Perhaps nothing showcases technology’s ability to innovate and change lives better than the science behind 
renewable power. Solar power’s high cost is well-established, but scientists at CalTech are developing cells with such hyper–
efficiency they could potentially eclipse the question of price.

Grid Can Be More Reliable With More Renewables

If the United States stops burning coal, shuts down one-quarter of existing nuclear reactors and trims its use of natural gas by 2050, the resulting increased reliance on wind, solar and other renewables will not result in a less reliable electricity grid.
