The value of solar PV completed in 2011 alone in the U.S. is $8.4 billion. Globally, the value was $93 billion. 100,000 people are employed by 5,600 solar companies throughout the U.S. - across all 50 states.
There is a wide range of utility experiences, but about 70% of solar activity is concentrated in the top 10 utilities as measured by our annual survey (www.sepatop10.org). The top 50 utilities encompass greater than 95% of the solar.
Seven of the top 17 states with the most rapid growth in the clean tech sector are considered swing states for the 2012 presidential election. Numbers like these suggest we are entering an era in which politicians who unfairly criticize or otherwise ignore clean tech run the risk of alienating a bedrock constituency: job holders, most of whom vote. We all need to understand that green jobs and clean tech are not merely the idle dreaming of a small group of partisan activists and insiders, but a source of livelihood for millions of Americans, literally in all parts of the country. What's more, their numbers are growing every day.
Peak oil? coal? gas? tar sands? shale gas? or any such? New discoveries seem to outpace all fears of early shortages. CO2 and AGW worries groundless? The jury is still out on that. Does that mean we can live free of any worries and carry on without any further need for doomsayers and troglodytes? Well yes, based on such questions. But could it just be possible that these are not the right questions to ask as they might produce wrong answers and consequently lead to wrong policies and investments?
The ASES National Solar Tour is the world's largest grassroots solar event. More than 160,000 participants will visit some 5,500 buildings in 3,200 communities across the U.S.
Current stretched porous film battery separators for lithium ion batteries are thin, strong, and provide a good barrier between electrodes, at the cost of having very high internal resistance and low ionic flow due to low porosity and high "dead space" that come from starting with a solid material and trying to impart porosity. This work uses an alternative approach, where linear nanofibers and microfibers are combined in wet laid nonwoven processes to give separators that are strong and thin, but have higher porosity (60-70%) and so have much higher ionic flow.
Standards-based solutions were instrumental in the exponential growth of the Internet. For the Smart City, public electrical infrastructure ecosystem to expand, development, application and worker training of interoperability standards is an important strategic foundation from which to grow. This convergence of intelligent transportation systems with the Smart Grid, is allowing the Smart City concept to gain hold in many areas of the US and around the world.
As the technology of renewables advances, and as their track records continue to show stable returns, pension funds will continue to increase their investment in renewables, either through direct investment, infrastructure funds or private equity funds.
The S.P.M. Mill operators initially tried using Oscillator and Vortex technology flow meters. They found that these flow technologies contain moving parts or orifices and were unable to measure flows accurately at the low flow rate demanded by this digester application.
On average, a California solar system will pay for itself within five to 10 years, depending on the size of the system. However, if the system is leased and homeowners put little down upfront, the solar system will begin paying for itself on day one, creating instant savings.
The iSolar Exchange online marketplace is designed to create a secure site that connects the entire supply, manufacture, and delivery channels for solar and renewable energy products and services - worldwide. That's all we do - that's all we focus on.
In current technology about 30% of the light is reflected back into space. We have created a 3-dimentional structure in the silicon that virtually eliminates reflection by causing the light to bounce around within the structure until it is fully absorbed.
Fuel cells can help resolve many issues facing ports. By deploying this clean and modern technology, ports can reduce pollution and increase operational efficiency. Fuel cells generate electricity using electro-chemical reactions, not combustion, so there are no polluting emissions, only water and heat as by-products.
Algae converts at a very high efficiency into biocrude, as it has lots of caloric value and happens to have the same molecular structure as petroleum. So out of all the whole biomass sources, algae is probably the most efficiently converted to biocrude.
While the addition of each Plug-in Hybrid Electric Vehicle (PHEV) to the street is a victory for the environment, their widespread adoption will present another potential challenge to the power distribution system, particularly in urban networks.

The Darfon G320 is the microinverter solution for today's high-power solar modules. The G320 handles 60- and 72-cell modules up to 350W DC and outputs up to 300W AC. The G320's 3-phase configuration accommodates the electrical distribution systems of most commercial buildings and to reduce, if not eliminate, the need for expensive transformers. The G320 comes in four voltage/phase configurations, so it can be installed in residential, commercial or utility applications.
