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.
Siemens announced it has received a multimillion dollar order from Ansaldo Honolulu, a joint venture, to electrify the track for the new Honolulu rail transit system. A first for the state, it is scheduled to be completed in 2019.
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.
With the economy still reeling from the effects of recession, unemployment, and wavering business and consumer confidence, electrical contractors (ECs) are re-evaluating their businesses and taking on new and different roles and business models in an effort to remain competitive.
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.
Efficiency and conservation have become well-established elements of the green power movement, and, in that regard, smart meters have become one of the primary tools to help consumers and utilities do their part.
In the years that renewable power has been fighting for market competitiveness, overcoming the high capital costs compared to conventional energy sources has always been the big challenge. Now, for at least one form of renewable energy, it appears that challenge may have been met.
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.
The Lucky Corridor, approximately 93 miles of planned new electrical transmission, consisting of double-circuit 230-kilovolt (kV) line in New Mexico, cleared a hurdle with a memorandum of understanding (MOU) with the Western Area Power Administration, a power marketing administration in the U.S.
It’s no secret that, with deeper systems integration, new technologies, and a focus on efficient and alternative energies, the electrical industry is growing and changing in ways that were hard to predict even just a decade ago.
