Renewable Energy Surpasses Coal in the UK
Written by Keith Kohl for Energy & Capital: For the first time ever, more energy in the UK was supplied by renewable sources than coal. For an entire quarter. Wind, solar, and bioenergy checked in at 25% of the energy supplied.
All of this was possible due to the fact that more wind turbines and solar panels were installed, which must be a good amount if you want to compare it to the same period last year, for which these energy options only accounted for 16.4% of electricity.
Recently, the UK has been working to close aging coal and nuclear power plants.
Of course, this will lead to its own issues...
[Solar Panels] Conservative ministers collectively believe that the subsidies given to renewable energy were too numerous, going so far as to suggest plans for an 87% reduction of solar power, and to cut support for onshore wind farms.
With that kind of spending cut, it's not surprising to hear that industry execs believe these actions would unjustly put an end to renewable energy just as it was gaining traction. Cont'd...
Can the U.S. Jump-Start Offshore Wind Power?
By Camille von Kaenel and ClimateWire: The Department of Energy has awarded around a half-million dollars to New York, Maine, Rhode Island and Massachusetts state organizations to cooperate on scaling up the offshore wind industry in the region. Under the leadership of the New York State Energy Research and Development Authority (NYSERDA), the group will lay out a collaborative road map by the end of the year on how to build up the new industry. The project largely aims to reduce the cost of offshore wind projects, which has been a barrier to development, and establish a regional supply chain. Industry and state representatives learned about the federal grant at the first-ever offshore wind summit hosted by the White House yesterday. Offshore wind has struggled to take off in the United States. Europe, meanwhile, has more than 80 offshore wind farms with more than 10,000 megawatts of capacity. The White House summit marks a renewed effort to get the industry going in the United States, said various attendees. Cont'd...
Five More Myths About Solar Energy - And The Real Facts
In an earlier article, Midsummers CEO Sven Lindström outlined some of the most common myths about solar power. Here are five more of the most common solar energy myths - coupled with the real facts.
Researchers develop cool way to improve solar cell efficiency
By Kelly Hodgkins for Digital Trends: A team of engineers from Stanford University have invented a cool way to improve the performance of solar panel arrays. A new material that the team produced literally will lower the temperature of solar cells even while they are operating in full-strength sunlight. As the solar cells cool, their efficiency will rise, leading to significant gains in the amount of energy harvested from the sun.
Solar panel technology has improved by leaps and bounds, but the technology has a flaw that limits the efficiency of the system. The panels must face the sun to operate, but the heat from this exposure diminishes their ability to convert light into energy. The hotter they get, the less efficient they become. This issue has perplexed the industry for years, but the Stanford team may have discovered a material that can help dissipate this excess heat without affecting the operation of the solar array.
The solution, proposed by Stanford electrical engineering professor Shanhui Fan, research associate Aaswath P. Raman, and doctoral candidate Linxiao Zhu, uses a material that is able to capture and emit thermal radiation (heat) away from the solar call. While deterring heat buildup, the thin, patterned silica material does not block sunlight, allowing the photons to enter the solar panel where they are converted to energy. It’s a win-win situation, allowing the free flow of sunlight and the removal of excess heat from the system. Cont'd...

Wind turbine technology stores excess wind power for when gusts turn to breezes
Megan Treacy for TreeHugger: A new technology developed by University of Nebraska-Lincoln electrical engineering doctoral student Jie Cheng solves both of those problems by harnessing the excess wind energy usually wasted as spillage and storing it for use when wind speeds dip, making wind turbines more efficient and consistent.
Cheng's system converts and directs the extra wind energy to an air compression tank, where the energy is stored until wind speeds dip below the maximum capacity. Using a rotary vane machine that is connected between the turbine's gearbox and generator, excess energy is diverted and stored in the air compression tank. When the wind dies down, the tank then kicks in and reverses airflow back to the rotary vane machine to generate electricity.
In a recent study of his prototype, Cheng found that a 250-kW system would produce an additional 3,830 kWh of electricity per week or an additional 16,400 kWh per month based on historical wind data from Springview, Nebraska. That extra electricity is about 18 times the monthly energy use of a typical American household. Cont'd...

El Niño Buffers U.S. Wind Power Dreams
Tim Maverick for Wall Street Daily: The National Oceanic and Atmospheric Administration (NOAA) made it official last week. The current El Niño is classified as a strong event.
An El Niño falls into the “strong” category if weekly sea surface temperatures depart from the average by more than two degrees Celsius.
In fact, this El Niño has nudged ahead of the 1997 El Niño as the strongest in the modern era!
Meteorologists believe this occurrence is actually the most potent since 1948. And it’s expected to persist through winter and into spring.
Every El Niño’s effects are different. At the moment, this one is having a surprisingly negative effect on the wind power industryin the United States.
You see, this occurrence of El Niño has produced the weakest winds across the United States in 40 years. Forecasters say this situation will continue and may even worsen through the spring of 2016. Cont'd...
SPI 2015: Tax credit sunset preoccupies a fast-maturing industry
By Herman K. Trabish for UtilityDIVE: Solar photovoltaic (PV) installed capacity is expected to reach 7.7 GW in 2015, up 24% from 2014, according to the Solar Energy Industries Association (SEIA) and GTM Research.
From July 2015 to December 2016, the report forecasts the U.S. solar PV marketwill add 18 GW, which is more than the cumulative capacity built by the industry up to the middle of 2014.
But there are some headwinds for the sector. In a sign it has reached a level of maturity achieved recently by the wind industry, solar advocates now face an uphill political battle for the industry's most vital federal incentive
The mandated term of solar's vital 30% federal investment tax credit (ITC), in place continuously since 2008, will end on December 31, 2016. Beyond that deadline, the tax credit provided at the end of a project’s first year of operation will fall to 10% for commercial investments in solar and to zero for residential solar investments.
SEIA is mounting a multi-million dollar lobbying campaign to secure a five-year extension that will get the industry to 2020, when it hopes the Clean Power Plan can take over to help boost growth. Cont'd...
