The $14 billion industry, the world’s second-largest buyer of wind turbines, is reeling from a double blow -- cheap natural gas unleashed by the hydraulic fracturing revolution and the death last year of federal subsidies that made wind the most competitive of all renewable energy sources in the U.S. Without restoration of subsidies, worth $23 per megawatt hour to turbine owners, the industry may not recover, and the U.S. may lose ground in its race to reduce dependence on the fossil fuels driving global warming, say wind-power advocates. They place the subsidy argument in the context of fairness, pointing out that wind’s chief fossil-fuel rival, the gas industry, is aided by the ability to form master limited partnerships that allow pipeline operators to avoid paying income tax. This helps drive down the cost of natural gas. “If gas prices weren’t so cheap, then wind might be able to compete on its own,” said South Dakota’s Republican Governor Dennis Daugaard. Consider that gas averaged $8.90 a million British thermal units in 2008 and plunged to $3.73 last year, making the fuel a cheaper source of electricity for utilities. Congress allowed the wind Production Tax Credit to expire last year, and wind farm construction plunged 92 percent.
New solar photovoltaic (PV) demand added during the first quarter of 2014 exceeded 9 gigawatts (GW), which was 35 percent more than the previous first-quarter record, set last year. In fact, every quarter in 2014 is forecast to reach new highs, with trailing 12-month demand at the end of Q1 2015 forecast to exceed 50 GW for the first time, according to findings in the latest NPD Solarbuzz Quarterly report. The record level of demand achieved in the first quarter was driven by strong growth in Japan and the United Kingdom. These two countries combined accounted for more than one-third of global solar PV demand in Q1 2014 and set new quarterly records for PV deployed.
The world's largest solar plants sure look amazing, but for those with inquisitive minds they raise one big question: how the hell do they keep all those panels clean? Nowadays, using robots like this! This video shows the newly installed robotic cleaning system at Ketura Sun Solar Park. Until now, the panels covering the 20-acre site were only cleaned about nine times a year—a laborious task, performed infrequently due to expense—which in turn led to sub-optimal plant efficiency. Now, though, a robotic army—designed and made by Israel-based Ecoppia—swarm over the panels to keep them clean. The 100 centrally controlled automatons set to work at nighttime, using microfiber pads and controlled air flows to push dirt from the surface of the solar panels. The robots move up and down their own aluminum frames to avoid loading the panels, and during the day they sit at the bottom and charge using electricity generated by the plant. So, now you know.
On Wednesday, March 27th, the largest state in the contiguous United States got almost one-third of its electricity by harnessing the wind. According to the Electric Reliability Council of Texas, which manages the bulk of the Lone Star State's power grid, a record-breaking 10,296 MW of electricity was whipped up by wind turbines. That's enough to provide 29 percent of the state's power, and to keep the lights on in over 5 million homes. ERCOT notes in a statement issued today that "The new record beats the previous record set earlier this month by more than 600 MW, and the American Wind Energy Association reports it was a record for any US power system."
The global clean-energy picture for 2013 was a classic good news-bad news story, according to the Clean Energy Trends 2014 report issued today by clean-tech research and advisory firm Clean Edge, Inc. The industry saw dazzling growth, success, and rising stock prices in some sectors – most notably solar photovoltaic (PV) deployment – but downward trends and policy and finance hurdles in others. Last year also marked a significant transition in the history of clean energy: for the first time since Clean Edge began tracking global markets in 2000, the world installed more new solar PV generating capacity, 36.5 gigawatts, than wind power (35.5 GW). Record levels of new solar deployment in China, Japan, and the U.S. combined with a down year in the wind industry to create this unprecedented crossover. The global solar market's continued double-digit growth of 15 percent, plus a modest uptick in biofuels' market size, was not enough to overcome the wind industry's lackluster performance. As a result, combined global revenue for solar PV, wind power, and biofuels held nearly steady at $247.6 billion, down just slightly from $248.7 billion in 2012.

Inland sites can offer sufficient wind yield for wind-farm operation. Initial results obtained from a TÜV SÜD test wind mast show that wind yield depends on the specific location.
At Algenol, algae is combined with carbon dioxide, salt water and sunlight in Algenol's proprietary photobioreactor system to produce thousands of gallons of fuel per acre.
Waste heat to electricity uses less fuel to produce a given energy output, and avoids transmission and distribution losses that occur when electricity travels over power lines. It also decreases the impact of outages when the power grid goes down.

The benefits of a centralized database and platform for managing data extend beyond the scope of one software product.
Understanding the water needs for energy and power production is key for using a nexus approach. In a nexus approach, knowing the impact of water and the interlinkage is essential for determining optimum choices for energy technologies.
Although we have over 12, 000 PV modules in the database today, we are always searching for new modules. Manufacturers and consumers can contact us if they have modules that are not listed.
Already in the lead as the fastest-growing clean and renewable energy source in America, solar power is growing to account for 29% of new American electricity, trailing just behind natural gas at 46%.

Siemens is investing more than EUR190 million (GBP160 million) in new offshore production facilities in Great Britain. Production of rotor blades for offshore wind turbines of the 6-megawatt class is planned, with a new logistics- and service centre slated for Hull. The British Prime Minister David Cameron and Michael Suess, member of the managing board of Siemens AG and CEO of the Energy Sector will reaffirm their common dedication to these projects this afternoon in Hull. "Our decision to construct a production facility for offshore wind turbines in England is part of our global strategy: we invest in markets with reliable conditions that can ensure that factories can work to capacity. The British energy policy creates a favourable framework for the expansion of offshore wind energy. In particular, it recognizes the potential of offshore wind energy within the overall portfolio of energy production", stated Michael Suess, member of the managing board of Siemens AG and CEO of the Energy Sector. The offshore wind market in Great Britain has high growth rates, with an even greater potential for the future. Wind power capacity has doubled here within two years, to roughly 10 gigawatts. By 2020, a capacity of 14 gigawatts is to be installed at sea alone to combine the country's environmental objectives with secure power supply. Projects for just over 40 gigawatts are currently in the long-term planning.

The NeON R module features "Back Contact" cell technology delivering an entirely black panel that is aesthetically pleasing and energy efficient. The cell's seamless, surface blends perfectly into nearly all rooftop designs while the module's electrodes are positioned on the rear of the cell. Using LG's N-type cell structure, the panels produce 365W of energy, up to 7.3kWp, compared to 5.8kWp of the p-type cell. The module's new design minimizes LID, thereby delivering a longer lifespan and increased energy output.
