By measuring and monitoring solar thermal system performance, installers can correct mistakes and fine-tune and optimize systems. As a result, US consumers are likely to regain confidence in the technology, spurring what is expected to be a burgeoning market for solar hot water heaters.
MicroCSP power projects all include sun tracker and thermal storage. The cost is around the same as PV but you generate more electricity per day because of the tracker/storage combination so you have a lower cost of energy.
Recent advances in materials science have led to the development of innovative new materials that provide enhanced durability to photovoltaic modules. Unique polymeric thin film technologies, such as ethylene-tetrafluoroethylene (ETFE) frontsheets, provide modules with the protection they need to perform at high levels even when exposed to the elements.
Research has shown that LEED buildings consume over 25% less energy, have 13% lower maintenance costs, 27% higher occupant satisfaction and a 33% reduction in GHG emissions compared to the average commercial building.
Bard College and Hawthorne Ridge Retirement Community are two examples of down to earth solar energy projects that make a difference.
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.
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.
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.
I wrote this article for HomeToys.com, 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.
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.
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.
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.
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.
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.
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.
