Credit does not necessarily go to utilities for the expanding role of green power. Some states, including Arizona and Oklahoma, have made it less cost-effective for homeowners to install their own solar panels.
As the electrical grid gets smarter and the number of severe weather events increases, many may wonder about the reliability of the U.S. electrical power system. A group of researchers put together some hard numbers on the matter and concluded that many areas need improvement.
Basic economics suggests that, when prices go down, more people make purchases. As such, recent declines in the installed costs associated with residential and nonresidential solar photovoltaics (PVs) bode well for electrical contractors.
Because of increased pressure from government regulators to provide efficient energy systems, Boston-area developers must enlist experienced contractors with proven track records of providing sophisticated energy systems that ensure high quality and reliability, according to Matthew Guarracino, busi
The growth of renewables and other energy technology is not just changing the way consumers get their power. The trend toward nontraditional fuel sources also is contributing inadvertently to the growth of other, previously ancillary systems that are riding the wave of green technology.
While energy efficiency continues to play a prominent and growing role in the larger movement to transform the way society generates and consumes power, debate continues over the question of whether it really works. A recent study should help put that debate to rest.
Austin, Texas, has an aggressive plan for alternative energy. The “Austin Energy Resource, Generation and Climate Protection Plan to 2025” sets the city’s goal of sourcing 55 percent of its energy from renewables by the end of the plan’s term.
It has only been a few years since incandescent lamps were phased out. It has been even less time still since their heir apparent, compact fluorescent lamps, began losing ground to light-emitting diodes (LEDs).
When conjuring images of renewable energy, hydropower is typically not the first thing that comes to mind. That’s usually wind, solar or geothermal. Further eroding hydro’s place, it wasn’t long ago that environmental opposition brought new dam construction to a halt.
Electrical contractors interested in getting involved in customer solar installations and maintenance (residential, retail, commercial, governmental and industrial) may look at the “official” numbers on solar generation and conclude that, while some opportunities may exist, they are not appealing en
When it comes to policymaking in the energy arena, few decisions are going to make everyone happy, especially when the issue is controversial. Clean air is no exception, and the Obama administration waded into a policy knot when it took on the problem of power-plant emissions.
For every opinion, there is a dissenter. For every bit of conventional wisdom, there is at least some counter evidence. While common sense and popular appeal seem to point to a smart grid that is more efficient and less disruptive, a recent study reaches a very different conclusion.
A report published by Navigant Research, “Direct Current Distribution Networks,” examines the opportunity for direct current (DC) distribution networks in four key market segments: off-grid/bad grid telecommunications, data centers, commercial building grids and off-grid military applications.
