The future of energy efficiency may be more than saving energy. It may also be efficient energy capture, storage and delivery. Technologists, engineers and some forward-thinking manufacturers are working to set a bigger table for direct current (DC), and one effort may be all-encompassing.
In the early days of electrical generation and transmission, much hullabaloo was made over the respective value of alternating current (AC) versus direct current (DC) technology, and the reigning geniuses of the 1880s, Nikola Tesla and Thomas Edison, waged a metaphorical war over the issue.
Renewables are always setting some kind of record in their never-ending quest for market parity. Recently, in Germany renewables broke new ground by producing nearly 100 percent of the country’s electricity, if only for a short time.
In January 2014, a weather front known as a “polar vortex” descended from Canada’s arctic north and brought frigid temperatures and heavy snow and ice as far south as Texas and eastward to the Mid-Atlantic and New England.
Denmark is shaping up to be wind power's sweetheart. In 2015, it generated 42 percent of its power with wind turbines. It is the highest portion of any country's energy needs fulfilled by wind. And Denmark is no stranger to this podium.
TechRepublic.com reported in October 2014 that the United States has more electrical grid blackouts than any other developed nation and that, according to the U.S. Department of Energy (DOE), demand for electricity has outpaced transmission rates by 25 percent every year since 1982.
San Diego Gas & Electric’s (SDG&E) microgrid supplied electricity to 2,800 customers in Borrego Springs in San Diego County, Calif., on May 21, 2015, during planned grid maintenance. This marked the first time a U.S.
In the energy field, who we receive our power from and what we receive may soon be our choice. In fact, some customers are already in the driver’s seat through something called community choice aggregation (CCA).
According to a report by MarketsandMarkets research firm, the wireless-power-transmission market will reach $17.04 billion by 2020, growing at a combined annual growth rate (CAGR) of 60.49 percent from 2014 to 2020.
In the utility sector, not many issues cause industry stakeholders more anxiety than the aging infrastructure and continuously increasing demand. Around the country, utilities are investing heavily to keep up with degradation and power-hungry consumers.
In January 2013, the Edison Electric Institute—the leading advocacy group of the investor-owned utility industry—released a report predicting “significant future disruption to the utility business model,” thanks to growing adoption of distributed generation resources.
The landscape of power in this country is changing at a rapid pace. Forces external to the industry, such as climate change, and those with a more intrinsic link, such as technology and consumer demand, have combined to place great pressure on the nation’s delivery system.
As the nation continues to embrace alternative energy sources, the challenge of distribution becomes more pronounced. Utilities, providers, transmission operators and manufacturers need to find an efficient and reliable way to get all that new power to the grid.
New York recently strengthened its power supply with the completion of two projects: an underground and underwater 660-megawatt electric transmission project between New Jersey and Manhattan and a low-cost, commercial battery-storage system on the campus of the City College of New York (CCNY).
