In October, the National Electrical Manufacturer’s Association (NEMA) continued its lighting product monitoring, revealing some interesting results that confirm change is occurring at the lamp level in the lighting industry.
Storage is the missing link that will enable renewables to become a reliable supply of mainstream energy. It is no wonder then that, as renewables expand in their reach, new and innovative forms of storing that energy also become more relevant.
In this digital world, we’re never far from our smartphones and tablets. Shopping on the web has become the new normal, and though we know left from right, our GPS is at the ready. That’s a lot of information, and we need data centers to house, organize and transmit that big data.
With the goal of reducing power consumption of the ever-expanding population of high-density data centers, the Electric Power Research Institute (EPRI) recently investigated the energy-reduction potential at three U.S. data centers.
As alternative-energy sources become more commonplace, the need for infrastructure to support their expanding reach into mainstream energy markets is also on the rise. Microgrids have emerged as an ideal technology to meet this growing demand.
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.
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.
It is interesting to monitor how the biennial “Profile of the Electrical Contractor” research study has changed over the years. It shows how the EC evolves with the times, including adding communications work to their offerings. Those who responded to market shifts made the move to profit.
Are wireless controls taking market share from their wired brethren? A report released by Navigant Research says they are. Growth in the sector is expected to continue, with annual worldwide shipments of wireless nodes for building controls forecast to surpass 36 million by 2020.
