Analysis Group finds it is market forces - primarily low-cost natural gas and flat demand for electricity - that are causing some coal and nuclear power plants to retire, and not state and federal policies supporting renewable energy development. The report finds that the changing electricity resource mix poses no threat to reliability of the nation's power system.
The International Resource Panel, a group of eminent experts in natural resource management hosted by the United Nations Environment Program, recently provided a global assessment of the benefits, risks and trade-offs encountered when energy efficiency technologies are deployed alongside low-carbon electricity supply technologies.

In some cases, rural America is seeing the smart grid arrive at their doorstep well before their urban and suburban counterparts. This is due to the not-for-profit structure of rural co-ops, which makes them uniquely responsive to consumer demands for technological solutions to traditional grid problems, according to the National Rural Electric Cooperative Association's new president, Phil Carson.
The U.S. Energy Information Administration recently reported that primary energy consumption in the United States in 2016 totaled 97.4 quadrillion British thermal units (Btu), a slight increase from the 2015 level. Consumption of coal decreased by 9%, nearly offsetting increases in the consumption of renewables, petroleum, natural gas, and nuclear fuel.
"The Oleo Sponge offers a set of possibilities that, as far as we know, are unprecedented," said co-inventor Seth Darling, a scientist with Argonne's Center for Nanoscale Materials and a fellow of the University of Chicago's Institute for Molecular Engineering.
The smart grid security market size is estimated to grow from USD 4.29 Billion in 2016 to USD 7.00 Billion by 2021, at a Compound Annual Growth Rate (CAGR) of 10.3% during the forecast period, according to a new report from MarketsandMarkets.
The white paper, co-authored by Panasonic, Xcel Energy, and Younicos, details a unique solar-plus-storage microgrid project under way at Denver's transit-oriented development, Peña Station NEXT. The battery energy storage system will deploy five use cases: 1) solar energy grid integration via solar smoothing ramp control and solar time shifting, 2) grid peak demand reduction, 3) energy arbitrage, 4) frequency regulation, and 5) backup power for Panasonic's network operations center.
According to the author, who is a data architect at the Dutch Distribution System Operator (DSO) Alliander, his company developed the Open Smart Grid Platform to be "an open, generic, scalable, and independent Internet of Things platform that enables municipalities and power distribution companies to easily control and monitor various public service objects with any application and with any communication infrastructure."
The technology -- called hydrothermal liquefaction -- mimics the geological conditions the Earth uses to create crude oil by using high pressure and temperature to achieve in minutes something that takes Mother Nature millions of years.
"While Li-ion leads in terms of technology, distributed energy storage systems (DESSs) are becoming increasingly popular in several regions, accounting for around 14 percent of new system capacity announced in 2016 -- the highest percentage of any year on record," says Ian McClenny, research associate with Navigant Research. "DESSs are generally much smaller than utility-scale systems and are expected to thrive as they become more cost-effective and productized, leading to more streamlined installation and opening new markets."
