Solar Power International 2011 Report

Solar Power International 2011 took place in Dallas, Texas, with a goal to generate powerful new ideas, connections and business opportunities for the solar industry. An estimated 24,000 professionals and over 1200 exhibitors from businesses spanning the entire spectrum of the industry will be on hand for four days of product exploration, discussion, professional enrichment and networking. The AltEnergyMag team has taken some time to put together a list of some of the interesting new products and services seen at this year's show.

Removing the Rare Element Limitations from Solar Energy

Many of the cutting edge thin-film technologies require rare elements that are a finite resource already in short supply. There simply is not enough material on the planet to make these devices for worldwide consumption.

Understanding Solar Power Purchase Agreements
A Guide to Hosting a Solar Energy System

Under the terms of a solar PPA, a solar services provider installs solar equipment at a host business, government site, university, or other organization, and the host agrees to buy the solar electricity generated by the system for a fixed price and term, usually 5-20 years.

On Energy Management, Manufacturing and Factory Automation

I wrote this article for, our Home Technology website but it applies to Alternative Energy as well. It's not enough to monitor our energy use. We don't really care about that unless it does something to change our lives or save us money. So, let's put a solar system on the roof. Now that can do both of these things and should attract our attention. But let's take it a step further. With that solar system there is a new variable in the mix --- FREE CLEAN ENERGY. What can and should we do with it.

Don't Forget: NREL are the Good Guys. And so is solar energy.

The Denver recently reported the NREL was going to lay off 10 percent of its employees. It took about two light seconds for a popular Washington D.C. news site to pronounce the layoff a "scandal," because NREL had taken federal stimulus money. That is silly. NREL, of course, is where the Department of Energy tests and develops new materials and techniques for solar, wind and other kinds of energy.

Harvesting Energy from Organic Materials

Harvest uses a platform of technologies - including advanced composting, anaerobic digestion, and material recovery - to harness the full carbon, energy and nutrient value from discarded organic materials.

The OPDE Group

OPDE is a Spanish corporation with a global vision that specialises in photovoltaic solar energy systems. We have three business lines. OPDE develops, builds, and carries out maintenance of photovoltaic solar plants; PROINSO supplies modules, inverters, trackers, and other equipments for photovoltaic installations; MECASOLAR specialises in the design and manufacture of solar trackers, fixed structures, and foundation screws.

Q and A about Solyndria and the Clean Energy Industry

In 2009, there were 2.2 million green jobs in America, according to the U.S. Bureau of Labor Statistics. By July of this year, the number was 2.7 million, according to the Brookings Institution. That compares with 375,000 jobs mining coal, producing oil and gas and turning fossil fuels into consumer products.

Lithium-ion batteries for efficient storage of renewable energy and mobile power solutions

Lithium-ion technology is currently more economically and environmentally viable than other existing battery technologies. It will likely be both the present and the future of sustainable storage of renewable energy and mobile power solutions.

Iowa Now Gets 20% of Electricity from Wind

Iowa has led the nation in attracting wind energy manufacturers and building a robust supply chain that supports more than 2,300 jobs and involves over 80 Iowa businesses.

Plug Power Case Study: Wegmans Food Markets, Inc.

The idea of using hydrogen fuel cells instead of lead- acid batteries in the material handling equipment was introduced because of significant benefits offered by the alternative energy power source—increased sustainability, less maintenance requirements and operator self-sufficiency.

Concentrated Solar Power (CSP) - Global Market Size, Competitive Landscape, Regulations & Investment

In 2010, global CSP investments primarily came from Spain and the US. Of total investments in 2010, 59.2% were made in Spain and 28.8% in the US. Spain also recorded the highest number of installations in 2010. Annual CSP capacity additions reached 350MW in 2010 due to the introduction of the FIT scheme.

Production Cutbacks Insufficient to Prevent Solar Module Inventory Buildup

Current Production Plans and Demand Outlook Suggest Oversupply Will Be Maintained into Next Year

End of Summer Fuel Cell Road Trip

Many fuel cells are being used at locations that people would never expect. To follow up on our series of fuel cell road trip articles (, we've found some up and coming fuel cell destinations that are worthy of a stop on your next summer vacation.

A case for low cost and affordable Energy Management Devices

There is continuous and increasing demand to manage and control the usage in order to reduce costs. The need for lower consumption and cost savings runs across all sectors inclusive of local, state and the Federal Government as well as utilities, commercial and residential consumers of energy
