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.

Lithium-Ion Energy Storage Safety
04/15/13, Sean Hendrix, Chief Engineer , EnerDel, Inc.
Energy storage systems, like any energy or power system, carry some degree of risk. With today’s technology, these risks are largely understood and can be effectively reduced or mitigated.
Potential risks of smart grids are underestimated
04/15/13, Contributed by, TÜV SÜD Industrie Service
According to the study 'Security & Safety in a Smart Energy World', presented by TÜV SÜD at the opening of the 2013 Hannover Messe, the energy and manufacturing sectors are underestimating the potential risks involved in modernising power grids; awareness of the vulnerability of smart grids is negligible and protective action is rare.
Lessons Learned: Collaboration, Empowerment and Vigilance Key to Sites’ Successful Safety Culture
04/01/13, Bryan Stewart and John Valerius, Suzlon Wind Energy Corporation and Duke Energy Renewables
It takes more than perfunctory “safety moment” sharing and hard hat stickers to ensure employees and contractors make safety their top priority. In creating a viable safety culture, site leaders first identified the unique strengths of each company and exchanged lessons learned at other power generation facilities.
CHINA FACES $243BN CLIMATE FINANCE “GAP” PER YEAR BY 2020

Series of reforms being explored as China seeks to expand clean tech investment
A New Class of Rogowski Coil Split-core Current Transducers
04/01/13, Pierre Turpin, LEM Renewable Energy and Automation
Until now Rogowski coils have delivered at best a 2% positioning error. With this improvement, the error due to the positioning of the conductor is specified at a maximum of 0.65% of the measured value for a 15mm diameter conductor irrespective of where it is positioned, even if it is adjacent to the coil clasp.
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.
Interview with Sophie Parker of The Nature Conservancy
05/16/13, Sophie Parker, 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.
The End to the California Solar Initiative (CSI)
04/25/13, Alan H. Lee, Chief Executive Officer at, ecoSolargy
Decreasing incentive over time will help build resilience and not inflate the market. It is also important to offer varying levels of incentives for residential, commercial, affordable housing, and non-profit in order to ensure equality for the benefits of solar, and help those who need it most.
Leading Edge Erosion on Wind Turbines
04/15/13, Contributed by, 3M Wind Energy
Awareness is growing in the wind industry about the severe impact that blade leading edge erosion can have on wind turbine output. Recent research shows that erosion can lead to a loss in annual energy production (AEP) of up to 20 percent, costing thousands of dollars.

Solar Portfolio Continues Outperformance by Close to 10X
04/01/13, Peter Lynch for , InvestorIdeas.com
At the current time the market is overbought at a level which historically results in a pullback in the market closer to the 50 day moving average. As a result of this I have been setting our stop loss points very conservatively in order to make you that when a correction or pullback comes we will still lock in healthy profits.
Corrosion Control for Wind and Solar Equipment
04/01/13, Rick Grant, Russell Corrosion Consultants, Inc.
Coatings are the first preventative measure for all of these assets. Since most are being deployed in desert areas or mountainous areas or along the coasts, or sometimes in the water, choosing the right coating is imperative to achieve design life.
