Fuel cells are an evolving technology and a current new market for the electrical contractor (EC). As a result of research and development, fuel cells have become feasible to implement with greater capacity, reduced costs, increased reliability and improved efficiency.
With the Institute of Electric Efficiency reporting more than 36 million smart meters installed from 2007 through May 2012 and a target of 65 million by 2015, it appears that smart meters are here to stay.
As we enter the final month of the presidential election campaign, the political rhetoric remains heated. Among the many issues to be debated, renewable energies and the federal policies that support them will no doubt feature prominently.
More than 8 billion lamps illuminate the United States, accounting for nearly 20 percent of all electricity consumption in the nation, according to a study released by the Department of Energy (DOE). The “2010 U.S.
The International Energy Conservation Code (IECC) is a model residential and commercial building energy code produced by the International Code Council, an organization dedicated to building safety and fire prevention.
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.
Lighting continues to be a huge chunk of a building’s annual energy costs—between 20 and 40 percent. While the need for light will never go away, analyzing its costs through energy modeling can help secure the installation of more efficient technologies.
The Occupational Safety and Health Administration (OSHA) is in the final stages of updating the existing standard on electric power generation transmission and distribution (1910.269 and Subpart V) related to electrical protective equipment.
