Energy Policy:
Bill would increase Nevada renewable energy mandate to 80% by 2040
(February 17, 2017; Utility Dive; Peter Maloney)
A bill passing through the Nevada Assembly is proposing to increase the renewable energy portfolio standard from 20% to 80% by 2040 using a phased-in approach. The bill would count electricity sent from rooftop solar panels to the grid towards meeting the renewable energy mandate, which could further boost the rooftop solar industry of Nevada. -JPM


Nuclear:
How Toshiba Lost $6 Billion
(February 17, 2017; Bloomberg; Jason Clenfield, Yuji Nakamura, Takashi Amany, Pavel Alpeyev, and Stephen Stapczynski)
The nuclear industry was shaken by the news that Toshiba declared that its subsidiary Westinghouse, a major brand in the nuclear reactor industry, will not be offering to construct its reactors for future nuclear power stations. Toshiba was pushed to this limit by suffering through numerous delays and spending billions of dollars on overcosts on four of its nuclear reactors in construction in the southeast United States. -JPM

A half-wave rectified alternating current electrochemical method for uranium extraction from seawater
(February 17, 2017, Nature Energy, Liu et al.)
Although the majority of the Earth’s uranium supplies are in seawater, the low concentration makes uranium difficult to extract. This study demonstrates a method to extract uranium from seawater, which has important ramifications for nuclear fission. -RD


Solar
U.S. Solar Surged 95% To Become Largest Source of New Energy
(February 15, 2017; Bloomberg; Chris Martin)
In 2016 for the first time, the U.S. added more solar energy than in any other sector, including natural gas and wind. Solar production nearly doubled compared to 2015, especially due to new utility-scale fields. The industry is quickly becoming profitable, despite the president’s promises to enhance fossil fuels. -WA


Oil & Gas:
Transportation fuels: Desulfurizing diesel
(February 17, 2017; Nature Energy; Carole Lamonier)
Commonly used fuels such as diesel often contain molecules that form toxic substances when combusted. This paper demonstrates a potential method to reduce sulfur concentration in diesel, which could potentially reduce the environmental impact of various fuels. -RD

What Oil Crisis? Arctic Drilling Off Norway Set for Record
(February 14, 2017; Bloomberg; Mikael Holter)
Despite low oil prices, explorers are hoping to increasing drilling in the Arctic Ocean off Norway. Unusually low local sea ice, greater market efficiencies and favorable Norwegian finance plans have enhanced the plans. However, Greenpeace and other environmental groups are suing the Norwegian government, calling the plans irresponsible with respect to climate agreements. -WA


Wind:
The South Has Been Slow To Harness Its Wind, But That’s Changing
Historically, the Southeast has relied on coal-fired plants and even nuclear plants for energy, rather than taking advantage of the strong winds found at high elevations. Advances in technology, allowing for taller turbines, and the growing energy demand of tech companies has set change in motion and brought wind to the Southeastern energy grid. Farmers are jumping on the chance to lease their land out to a new 22,000 acre wind farm in North Carolina; it’ll generate enough energy to power 61,000 homes annually. -AD

Slow cooling and highly efficient extraction of hot carriers in colloidal perovskite nanocrystals                                                                                                         (February 8, 2017; Nature Communications; Mingjie Li et al)
Current solar cells have theoretical limits on maximum efficiency, due to certain properties of photoelectric materials. This paper revealed substantial improvements in extracting energy from “hot” carriers, which are electrons above a certain energy level. These processes could increase the efficiency of single solar cells, which, when stacked, could substantially improve solar efficiency. -RD

A hybrid electrochemical device based on a synergetic inner combination of Li ion battery and Li ion capacitor for energy storage
(February 7, 2017; Nature Scientific Reports; Jun-Sheng Zheng et al)
Energy density and power density are two of the most important properties in energy storage devices, but are hard to simultaneously realize. This paper describes the model of a hybrid Lithium ion capacitor, which could theoretically achieve both high energy density and power density, as well as a long cycle life. -RD

Turbine Breaks World Record for Wind Power Generated in Just One Day
(February 1, 2017; YaleEnvironment360)
A large offshore wind turbine from Denmark recently generated enough energy in one day to power 240 U.S. homes for a month. While the U.S. has just completed its first offshore wind project, many European countries have much more developed programs, with larger and more efficient offshore turbines. Nearly half of the energy in Denmark is generated by wind. -WA

Wind Power Surpasses Hydroelectric in a Crucial Measure
(February 9, 2017; The New York Times; Diane Cardwell)
For the first time in American history, the generating capacity of wind power exceed that for hydroelectric power this past year, according to the American Wind Energy Association. The rise in wind power in America has come from technological advances in wind turbine design and a slew of federal and state tax incentives towards wind power. However, in terms of actual electricity production, hydroelectric power edges out wind power by 30%. -JPM

Intelligence Test: A computer program that learns how to save fuel
(January 26, 2017; The Economist)
Researchers at UC, Riverside have made an artificial intelligence/machine learning algorithm that can drive vehicles more energy-efficiently. The algorithm works by breaking down the trip into small segments, and, based on the data of the situation, determines if the same energy-management system needs to be employed for the upcoming segment, or not. In a simulation controlling a hybrid car in southern California traffic, the algorithm yielded a 10.7% improvement in efficiency. -JPM
