The intermittent, yet often complementary, nature of wind and solar energy has long been observed and increasingly remarked upon of late. Minnesota’s Ecos Energy is looking to take advantage of that by building the state’s largest solar photovoltaic (PV) array on a 13-acre site in southwestern Minnesota, home to more wind farms than any other region state-wide, the StarTribune reports.

At 2-megawatts (MW), the solar power array can’t be considered large by any stretch, but it’s expected to provide enough electricity for 340 homes, about as much as a single wind turbine. Yet more significantly, Ecos Energy’s Slayton project will provide some trailblazing data as to whether or not intermittent solar energy and wind turbine arrays can be used in tandem to provide a more consistent supply of power to the grid.

Researchers from Georgia Tech University are working along two parallel tracks to develop energy-efficient robots based on the teamwork of ants and the movement of snakes. Envisioned for use in developing search-and-rescue robots, the technology could also be adapted to swell the ranks of robots with green jobs, for example in designing and fabricating solar cells, performing environmental monitoring or remediation, or subbing in for humans to perform potentially dangerous work such as wind turbine maintenance.

Four gigawatts (yes, 4,000 megawatts) of wind farm capacity have been held on lock-down and unable to move through the UK’s planning system due to Ministry of Defence (MoD) radar issues. However, it looks like that has all changed now.

The construction of new renewable energy generation capacity has fallen dramatically, as the big six energy suppliers pursue a “dash for gas” policy that could put the UK’s climate change targets out of reach and leave households with higher bills.

The number of new wind turbines built this year is down by half on last year. To date, 540MW worth of new turbines, on land and offshore, have been built this year – 200 onshore and 50 offshore turbines. Across the UK last year, 1,192MW of wind capacity was added.

As indicated in the previous post by the American Wind Energy Association (Top 10 Wind Energy Stories of 2011), below the picture are 5 wind energy trends the association recommends we watch out for. I’ll just add that I think there will be more and more media attention on the cost-saving benefits of wind energy, but that I think the clean-energy-hating-misinformation campaign will increase its attacks on wind energy. We’ll see — let’s hope for the first and pray the second is avoided or is rightly squashed by everyone not involved in that super-minority campaign. Lastly, from me, I imagine that we will see a more massive global increase in wind energy than ever before, with Asian and South American countries, especially, increasing their installed wind energy capacity.

The project consists of the installation of two 1.5-megawatt GE wind turbines which will provide clean electricity to the Air Force Center for Engineering. MMR’s main goal is to obtain all of its energy from renewables.

“This highly visible project was delivered safely, with high quality and ahead of schedule through the collective efforts of the entire AFCEE/ECC team. Each time I cross the Sagamore Bridge and see the turbines spinning, I am reminded of ECC’s contribution in bringing alternative energy to Cape Cod,” said Brian LaMont, program manager for ECC.

 

Although we can’t normally see the wind, we can feel its presence – however Colorado-based visual artist Patrick Marold has figured out a way to translate the wind’s movement into light. Using LEDs, polycarbonate tubes, and mini wind turbines, Marold has been documenting the shape of the wind through his Windmill Project. His installations involve hundreds of mini wind generators planted in breezy landscapes – as the wind blows across them, the LEDs light up based on the strength of the wind and where it blows. His project draws attention to the use of clean renewable energy and our interaction with the landscape and natural forces.

One of the biggest hurdles for integrating renewable energy from solar or wind sources comes from the question of storage – how can power be stored for times when the wind doesn’t blow or the skies are overcast?

Researchers at Stanford University are addressing this headlong and have reported the development of a new high-power electrode that is cheap, durable and efficient. If development continues as hoped, this discovery might potentially foster the manufacture of batteries large enough to provide for economical renewable energy storage on the grid.
