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.
The owners of Swauk Creek Ranch, a privately owned 3,865-acre reserve in Kittitas County, Wa., have partnered with Seattle-based energy and facility services firm McKinstry to develop and construct five wind turbines that will generate electricity for consumption in Kittitas County.
If wind- and solar-generated electricity are changing the way we look at our relationship to the grid, the transformation is only visible when the sources of that generation are in full force or, more specifically, when the gusts are strong and the sun is high.
The world’s cumulative solar photovoltaic (PV) electricity capacity surpassed 100 gigawatts (GW) in 2012, achieving just more than 101 GW, according to market figures from the European Photovoltaic Industry Association (EPIA).
Walmart President and CEO Mike Duke announced the company’s next step on the path to achieving its goal of being supplied 100 percent by renewable energy. Unveiled at Walmart’s Global Sustainability Milestone Meeting, the company committed to achieving the following by Dec. 31, 2020:
As electric vehicles (EVs) gain momentum in the race to win over motorists, one thing is still slowing them down: Many would-be owners can’t warm up to the idea of the long charging time.
If some analyst projections are correct, slow charging EVs may soon be outdated.
Double energy production by 2030 is the message that Dan Arvizu, director of the National Renewable Energy Laboratory (NREL), and a blue-ribbon panel of 20 energy experts recently drove home at the National Press Club in Washington, D.C.
Consider it a luxury. As a particular technology matures and becomes widely accepted, a new set of challenges emerge. Such is the case for the smart grid, which is passing the point of being a novelty and entering the realm of accepted practice.
