Berkeley Lab Study
Continued Reductions in Wind Energy Costs
Experts anticipate cost reductions of 24%-30% by 2030 and 35%-41% by 2050, under a median or 'best guess' scenario, driven by bigger and more efficient turbines, lower capital and operating costs, and other advancements
Solar on Houses Needed for 2020 Target
In the last ten years, the installed global solar energy capacity has multiplied nearly 50 times. The cost of purchasing and installing a solar panel has decreased by 80 percent in five years and is still falling. The comparable cost of electricity generation has made solar energy the cheapest energy source today, from being the most expensive only six years ago. This is truly a green revolution.

Industry praises bipartisan Governors' Wind and Solar Energy Coalition for seeking U.S. agencies' help to site wind projects
The U.S. wind energy industry today welcomed the support of a bipartisan group of 20 governors for further steps by federal agencies that could expedite siting of new wind farms, on land and offshore.
Think Wind Power Is Cheap Now? Wait Until 2030
Katherine Tweed for GreenTechMedia: In many parts of the world, wind power is cheap. That is particularly true in the U.S., where onshore wind already rivals the cost of natural gas in some regions.
But wind power will likely get even cheaper, according to new research from Lawrence Berkeley National Laboratory published in Nature Energy, with contributions from the National Renewable Energy Laboratory, University of Massachusetts, and participants in the International Energy Agency Wind Technology Collaboration Program.
The study surveyed more than 160 wind experts across the globe. Many had deep expertise in very specific regions, but the overall findings were similar: The cost of wind will continue to come down through 2030.
There are significant variations in the current costs for wind by region, but researchers "found a considerable amount of agreement” in overall reductions as a percentage of that total cost, said lead author Ryan Wiser, a senior scientist at Berkeley Lab. Cont'd...

China's Solar Panel Glut Undermines Its Agreement with the EU
By Reuters: “We fear a second wave of bankruptcies,” said the head of an association of EU solar producers. A sharp increase in solar power production in China and a sharp fall in domestic demand have sparked a sudden surge of cut-price exports, undermining a China-EU agreement to limit damage to European producers.
China produced 27 gigawatts (GW) of solar photovoltaic (PV) modules in the first half of 2016, an increase of 37.8 percent and installed 20 GW of new solar power capacity in the same period, three times as much as the same period a year ago.
However, demand has since tailed off. Solar projects operational since July face a reduced price paid by grid operators for their power. Cont'd...

New technology puts solar power to work all night long
ScienceDaily: Energy storage is crucial for taking full advantage of solar power, which otherwise suffers interruptions from cloudy skies and nightfall. In the past few years, concentrating solar power plants have begun producing additional electricity at night and during peak demand periods by using stored heat energy to propel a steam turbine.
Current thermal energy storage systems rely on materials that store less energy per kilogram, requiring more material at a greater cost to meet energy storage requirements.
Now, researchers at the U.S. Department of Energy's (DOE's) Argonne National Laboratory have designed an inexpensive thermal energy storage system that will be significantly smaller and perform more than 20 times better than current thermal systems. Cont'd...

HPS EnduraCoilTM Cast Resin Medium Voltage Transformer
HPS EnduraCoil is a high-performance cast resin transformer designed for many demanding and diverse applications while minimizing both installation and maintenance costs. Coils are formed with mineral-filled epoxy, reinforced with fiberglass and cast to provide complete void-free resin impregnation throughout the entire insulation system. HPS EnduraCoil complies with the new NRCan 2019 and DOE 2016 efficiency regulations and is approved by both UL and CSA standards. It is also seismic qualified per IBC 2012/ASCE 7-10/CBC 2013. Cast resin transformers are self-extinguishing in the unlikely event of fire, environmentally friendly and offer greater resistance to short circuits. HPS also offers wide range of accessories for transformer protection and monitoring requirements.
