Europe's offshore wind industry booming as costs fall

The Guardian:  On a sunny October morning, our boat passes the run-down relicts of Liverpool’s maritime past and heads down the river Mersey and into the Irish Sea. As we steam offshore, I see in the distance a cluster of tall structures that soon reveal themselves to be towers of a wind turbine array. Arriving at the windfarm, six miles offshore, the turbines rise as high as 650ft, taller than the tallest church in the world. Each of the turbines’ three shiny metallic rotor blades is nearly 300ft long. “A single rotation of an eight-megawatt turbine will cover the daily electricity consumption of an average British household,” says Benj Sykes, vice president of Dong Energy Wind Power, the company that is constructing and co-owns this wind project, as the boat rocks in five-foot swells.   Cont'd...

What is a Stacked Perovskite/CIGS Solar Module?

As this result shows that the combination of two PV technologies can outperform the power generation of single junctions the significance of this result shouldn't be underestimated as it breaks the current limitations of solar technology and shows that higher performing modules can be expected to become part of the energy system ...

Idaho company debuts solar power sidewalks

Nicholas K. Geranios for AP:  Scott Brusaw has a vision for the nation's roads. He believes the solar-powered glass pavers his company makes could transform thousands of miles of pavement into a new energy source. His business, Solar Roadways, recently unveiled its first public installation, in a downtown plaza in this northern Idaho resort town. It's 150 square feet of hexagon-shaped solar panels that people can walk and bicycle on. The company is working on proof that the panels, for which it has a patent, are strong enough and have enough traction to handle motor vehicles, including semitrailers. "Our plan is to replace all the asphalt and concrete," said Brusaw, noting concrete occupies over 48,000 square miles in the U.S. "If you cover it with solar panels, we can make three times our energy needs." Solar Roadways is among a growing number of companies embracing renewable energy as the U.S. aims to reduce carbon emissions by one-third from 2005 levels by 2030.   Cont'd...

NREL's Solar Radiation Research Laboratory Offers a Mesa-Top Home for Global Measurement Accuracy

The need for good data is foremost. A swing of just a half percentage point in the actual output of solar energy plants-compared to projected outputs-would represent about $165 million annually.

World's Largest Solar Project Would Generate Electricity 24 Hours a Day, Power 1 Million U.S. Homes

Lorraine Chow for EcoWatch:  The race to build the world's largest solar power plant is heating up. California-based energy company SolarReserve announced plans for a massive concentrated solar power (CSP) plant in Nevada that claims to be the largest of its kind once built. SolarReserve CEO Kevin Smith told the Las Vegas Review-Journal that the $5 billion endeavor would generate between 1,500 and 2,000 megawatts of power, enough to power about 1 million homes. That amount of power is as much as a nuclear power plant, or the 2,000-megawatt Hoover Dam and far bigger than any other existing solar facility on Earth, the Review-Journal pointed out. "It's a big project," Smith told the publication. "It's an ambitious project."   Cont'd...

World's First Farm to Use Solar Power and Seawater Opens in Australia

Kristin Falzon for EcoWatch:  Sundrop Farms, a tomato production facility that is the first agricultural system of its kind in the world, celebrated its grand opening in Port Augusta, South Australia, Thursday. Instead of soil, pesticides, fossil fuels and groundwater, Sundrop Farms uses only solar power and desalinated seawater to grow tomatoes across 49 acres. The water is pumped into the facility from the Spencer Gulf about 1.2 miles away where it is desalinated to water the farm's 180,000 tomato plants.   Cont'd...

This New Wind Turbine Could Power Japan for 50 Years After One Typhoon

Nick Mafi for Architectural Digest:  A typical typhoon produces wind speeds between 98 and 120 m.p.h. and usually leaves behind a trail of destruction. But a Japanese engineer has plans to harness a typhoon’s incredible wind energy and use it to power the nation. Atsushi Shimizu has just invented the world’s first typhoon-powered wind turbine—a roughly 18-foot structure that, with its three distinct prongs, somewhat resembles an egg beater. Don’t be fooled by the simple design, however. According to the Atlantic Oceanographic & Meteorological Laboratory, a mature typhoon can produce a level of kinetic energy equivalent to about half of the world’s electrical generating capacity. That means that after a single typhoon, Shimizu’s invention could power Japan for up to 50 years. Add in the frequency of the country’s typhoons—anywhere from three to seven each year—and the potential for massive quantities of renewable energy is unmistakable.   Cont'd...

US Solar Power Attitudes: 89% of Americans Support Solar Power

GetSolar.com sighting PEW Research:  Solar Power in America has gained wide acceptance over the last few years as prices have dropped and solar panel installation has greatly increased. Nine out of Ten Americans (89%) support solar power, regardless of political affiliation, according to a new report. Energy costs and environmental concerns rank highest on the list of reasons for such unprecedented support. The Pew Research Center, a polling and research group focused on global trends released a report highlighting the changes in American's attitude towards (solar power) in particular, along with other sources of energy. Solar power gained the highest acceptance of any form of power (see chart), with only 9% of Americans opposing it. Wind Power came in a close second at 83%, with other forms of more traditional energy generation taking a serious back seat (with half or less the support of solar).   Cont'd...

'New Age Energy Markets need a new approach to Risk Management

For energy traders and utilities, profitability in this complex and evolving market requires a full and complete picture of assets, operations, positions and risk exposures. Too many utilities are still labouring under a painful burden of data management challenges, including lack of automation, multiple disparate systems and data formats.
