Electical Contractor

Despite the growing popularity of solar power, the one thing that still casts a long shadow over the technology, and keeps everyone from installing a new photovoltaic (PV) system on their rooftop, is the high upfront cost. Recognizing this barrier, incentives are the norm.

Research into photovoltaic (PV) technology, like all renewables, is always striving for greater efficiencies and lower production costs. That quest often creates seemingly unimaginable possibilities. For example, consider solar glass with a view.

One of renewable energy sources’ biggest challenges is the intermittency of power generation. Finding a way to store power for later use helps make renewables more practical for tying into the grid where demand does not always coincide with the wind or the rising sun.

Advance promotion for NECA 2012 Las Vegas proclaimed that, “Our schedule is filled to bursting with rewarding activities.” No kidding! And no hyperbole.

Across the country, electrical contractors currently are or will be garnering contracts to upgrade traffic signals—replacing the incandescent bulbs with light-emitting diode (LED) lamps. Take a few tips from one company that has successfully completed a major project of this type.

The sustainable energy movement is full of surprises. Naturally occurring sources of power are always ready to emerge from the most unlikely global elements.

In the quest for a more energy-efficient future, no detail gets overlooked.

As U.S. utilities made projections for the summer months and predicted there would be enough capacity to meet demand with no outages, Mother Nature seemed to have other plans.

The United States is making the greatest push in its history to use renewable energy. However, thus far, one of the biggest obstacles for implementing renewables has been the United States’ exorbitant energy demand, which accounts for 26 percent of the world’s energy consumption.
