New Map Shows Solar Jobs Still Growing Faster Than the Economy
05/16/13, Chris Meehan, SolarReviews
Thanks to The Solar Foundation (TSF), individuals can now learn more about the solar industry in their backyard, their neighboring states and across the country. On April 18, TSF introduced a new interactive map that showcases the nearly 120,000 jobs in America’s booming solar industry in 2012. This is the first time that the public can easily access the data on a state-by-state basis, and explore what parts of the solar industry are biggest—including manufacturing, installing, sales, project development and associated jobs.
Wind Industry in the USA
05/16/13, Jukka-Pekka Mäkinen, The Switch
The debate of the PTC just took too long and put the players to uncertainty. Installations were pushed in 2012 to record level of almost 13 GW. This year will be a big dip to estimated 4 GW or so and midterm the installations should level on 7 GW level.
Case Study: Thomonde Hospital In The Central Region of Haiti

The Thomonde battery bank was designed for 40 percent depth of discharge and only one day of autonomy due to the large loads of some of the medical equipment and the availability of the diesel generator.
Making the Switch: From Fixed to Solar Tracker
05/16/13, Rich Nicol, AllEarth Renewables
I compared the cost per watt to install a standard pole mount, such as a DPW, and found it cost the same as putting up a standard tracker. And of course by tracking you get the additional power.
Interview with Sophie Parker of The Nature Conservancy

In areas of the Mojave that are ecologically intact, renewable energy development poses a major problem for plants, animals, and other species. Some major issues include: habitat destruction and fragmentation, water use, and bird mortality.
Alternative Energy Stories of the Day

The wind is faster at higher altitudes and wind power is directly proportional to wind velocity cubed. But mounting a turbine up high makes it more expensive to install and maintain, and requires a stronger tower to support such a top-heavy structure. Engineers at SheerWind have a solution: “scoop” the air from up high and bring it down low to drive a ground-level turbine. Oh, and while they’re at it, how about amplifying the wind speed too?
SheerWind coined the term INVELOX - INcreasing the VELOcity of wind - to describe its innovative design. Using a giant omni-directional funnel whose mouths are mounted at the top of a tower, INVELOX brings the wind down to ground level and sends it out through a narrow neck, which increases the wind speed, much like putting your thumb over the end of a garden hose and leaving a tiny opening will increase the water velocity. This makes the turbine smaller, decreasing its cost. And because the turbine is on the ground, routine maintenance doesn’t require climbing a tall tower. Funnel mouths facing all directions eliminates the need for the turbine to rotate towards the wind, resulting in fewer moving parts, less complexity, and increased reliability.
Since traditional turbines have relatively high start-up speeds (8 MPH or 3.6 m/s is typical), they can’t generate electricity at lower speeds. Because the INVELOX design increases the speed of the wind before it reaches the turbine, it allows the system to generate power at wind speeds as low as 2 MPH (0.9 m/s).
