Raging wildfires: Climate changes to blame for record season?
By Pete Spotts
The images are stark: soot-grimed firefighters steering bulldozers or wielding shovels to clear underbrush; curtains of orange flame tracing the contours of summits; aircraft dumping chemicals to slow a fire's progress.
Between Jan. 1 and early July of 2011, slightly more than 38,000 wildfires charred the landscape in the United States at a record pace. So far this year, wildfires have consumed just under 4.9 million acres of forest and grassland, a cumulative expanse the size of New Jersey.
That's 1 million more acres than fires consumed during the same period in 2006, which saw a record 9.9 million acres burned for the entire year.
Beyond the numbers, this year's fires may provide the first large-scale tests of the effectiveness of projects undertaken over the past decade to help forests survive wildfires, several specialists say.
The West's forests are adapted to deal with certain types of wildfires, researchers note. But since the mid-1980s, they add, some of these forests have experienced an increasing number of fires to which they are not well adapted.
Many researchers trace this shift in part to climate change.

Hybrid Moves Into Housing
By Brenda Krueger Huffman
(Chicago) – Recycling - Check. Conserving energy - Check. Hybrid car - Next car, check. Hybrid home system - What? Yes, it’s here. Hybrid has seamlessly, successfully moved into housing.
Safety Power, Inc. was initially started to provide homes with back up power. The company quickly grew to include renewable energy options and advising commercial and industrial clients with electrical conservation. Recently the company has come full circle and began marketing a new more capable type of renewable energy system for homes.
The award winning firm was voted one of the “Top 5 Sustainable Product Companies in Illinois” and continues to grow its residential client base in Illinois, Indiana, and Wisconsin. Safety Power also serves larger firms on the national level.
Robert Brazzale, President of Safety Power, a master electrician turned entrepreneur, began Safety Power in 2007. An avid member of Local First Chicago, Rob believes in assisting sustaining local economies with green collar jobs and belongs to many green orientated groups in Chicago and around the country.

Are electric car makers missing the trick?
by Martin Ott
I believe that electric car makers may be driving us all down the road that may result in the same sort of technology failures that we have seen in the past.
I'm not referring to the Sinclair scooter here but cast your mind back to the débâcle of Betamax v VHS home recording systems. The eventual winner was the technically inferior VHS but the battle was not resolved until innumerable consumers had paid out for worthless Betamax systems. Back in the 70's a similar conflict occurred over audio systems when America fell in love with the 8 track tape system that moved magnetic tape in a loop over the player head at a high speed resulting in a better sound. The world market finally dictated that the audio cassette was the way to go but not until millions of consumers had been lumbered with home and in-car systems that went down the technological cul de sac.

The Theni Wind Farm project was developed by CLP India Pvt. Ltd., one of the major wind farm project developers in India. Located in the south western part of Tamilnadu, a southern state of the country, the facility consists of 60 Vestas V82 geared wind turbines. As recognition of its contribution towards the successful execution of this wind power project SGS received Vestas award.
Each turbine at the wind farm has a capacity of 1.65 MW IEC Class IIB machine with a blade diameter of 82 m. After a six-month long completion period, the Theni Wind Farm was officially opened in May, 2010.
Acting as contract engineer during project execution, SGS was responsible for ensuring that all activities were carried out at the site by the contractor in line with the final agreement. In doing so, SGS supervised the quality of construction works, the fulfillment of the technical parameters and kept the project within the scheduled time and contracted price.

E.ON uses PPC's Broadband Powerline technology in smart grid project
by Power Plus Communications
Mannheim - Power Plus Communications AG (PPC), the leading provider of Broadband Powerline Communication systems (BPL) for smart grids has taken on a key role within an E.ON smart grid project to facilitate an extension of Cisco's Connected Grid Solution.
E.ON Westfalen Weser AG is currently trialing smart grid technology within its network of 1.3 million inhabitants and PPC's proven medium voltage BPL solution has connected substations in the project using the existing power grid.
Using BPL technology, standard compliant and IP-based data transfer rates of 5-30 Mbit/s can easily be achieved via the medium voltage cable itself. Within E.ON’s smart grid project, PPC's medium voltage technology facilitated the extension of Cisco's Connected Grid Solution. The Cisco smart grid Router and Switches used in the project are highly compatible with BPL networks, providing a real cost advantage over fiber optic networks – which can be much more expensive where cables are not pre-existing.
By combining their technology at Westfalen Weser, PPC and Cisco have ensured the evolution of fast and efficient smart grids which are controlled on an IP basis. This increases the reliability of the power grid, fulfills regulations and drives down costs. At the same time this modern smart grids communications technology makes it possible to effectively integrate renewable energy into the grid.

Chicago – Perhaps moving to the center is where we all need to be politically on the environment and effective spending compatibility. Not all green technology is crazy, and not all business profit or government expenditure is evil.
Even if you do not believe in man caused climate change, we can all agree leaving a cleaner planet and a more fiscally responsible government for the next generation is preferable to not doing so.
Perhaps green technology can be cost effective, and government fiscal responsibility may realistically include affordable green initiatives. Honest “life cycle analysis” and “life cycle cost analysis” study considerations should be a political compromise starting point both the left and the right can embrace.

Global warming: Impact of receding snow and ice surprises scientists
By Pete Spotts
Washington - A long-term retreat in snow and ice cover in the Northern Hemisphere is weakening the ability of these seasonal cloaks of white to reflect sunlight back into space and cool global climate, according to a study published this week.
Indeed, over the past 30 years, the cooling effect from this so-called cryosphere – essentially areas covered by snow and ice at least part of the year – appears to have weakened at more than twice the pace projected by global climate models, the research team conducting the work estimates.
The study, which appeared online Sunday in the journal Nature Geoscience, represents a first cut at trying to calculate from direct measurements the impact of climate change on the Northern Hemisphere's cryosphere. The study was conducted by a team of federal and university scientists who examined data gathered between 1979 and 2008.
