The U.S. housing crisis is the main cause of the global financial crisis. Therefore, the availability of loans for green field installations seems to be limited. However, financing for residential and commercial PV applications is still available.


There are six main building blocks of a solar-LED lighting system, basically representing the main energy-conversion steps required to capture energy from the sun, store it, and convert it to nighttime lighting.


It is a fact that the installation and set-up of solar thermal systems is no longer the realm of rare solar enthusiasts.


As for trends, I noticed several more thin-film companies exhibiting beside the grandpa of thin-films, UniSolar. These included Opti-Solar, Applied Materials (selling turnkey thin-film fabrication units) and Ascent Solar.


New technology is the "white horse" of affordable solar. Many customers hear or assume that technology is always going to improve over time and that will in turn bring down prices. The technology that we're using today is the same that we've been using since 1960 and it is the most efficient way to capture the unlimited, free, clean energy from the sun.


The world must now find ways to create the eternal paradigm for the infinite future of life on Earth, and I suggest that we may be able to begin the construction of an infrastructure that will still 100% sustainably serve those who live 1000 generations from now


Ultimately, battery-free operation is a key step in paving the way for truly green systems that do not adversely impact the environment. This environmentally-friendly approach can also extend the reach of sensing technology to distant and inhospitable climates and regions.


Biomass can play a major role in helping reduce reliance on fossil fuels by making use of efficient thermo-chemical conversion technologies. In addition, the increased utilization of biomass-based fuels will be instrumental in safeguarding the environment, generation of new job opportunities, sustainable development and health improvements in rural areas.

60,000 new-energy vehicles for China

China has decided to put 60,000 new-energy vehicles on trial run in 11 cities in the next few years as part of the pilot project of developing its eco-friendly, fuel-efficient alternative-energy auto industry, said sina.com today. China's EV (electric-vehicle)-oriented automakers, now only in a very small number, are required to reach the annual production of 500 new-energy vehicles by late 2009 and their total annual output should hit 10,000 units by 2010 for each of the chosen cities to have enough EVs for trial operation. At the same time, the vehicle standards, quality and stability will be strictly observed to meet the new-energy vehicle requirements. The Chinese government has invested at least 800 million yuan ($117.2 million) in developing the EV industry. Read More Here.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
