SOLAR POWER CONFERENCE DRAWS 22,500; TRENDS EMERGE
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.
SOLAR SYSTEM INSTALLATION - PITFALLS TO AVOID
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 TITANIC MOMENT
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
WIRELESS SENSOR NETWORKS FOR A GREEN WORLD
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.
WOODY BIOMASS AS ENERGY RESOURCE
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 .
Solar Energy Powers the Vatican
The Vatican on Wednesday activated a new solar energy system and announced an ambitious plan that could one day make it an alternative energy exporter. The massive roof of the "Nervi Hall" where popes hold general audiences and concerts are performed, has been covered with 2,400 photovoltaic panels to provide energy for lighting, heat and air conditioning. The new system on the 5,000 square meter roof will produce 300 megawatt hours (MWh) of clean energy a year for the audience hall and surrounding buildings. Officials say the Vatican is planning to install enough renewable energy sources to provide 20 percent of its needs by 2020, broadly in line with a proposal by the European Union. Read More Here.
Solar Powered Afterlife
Santa Coloma de Gramenet, a gritty, working-class town outside Barcelona, has placed a sea of solar panels atop mausoleums at its cemetery, transforming a place of perpetual rest into one buzzing with renewable energy. The power the 462 panels produces -- equivalent to the yearly use by 60 homes -- flows into the local energy grid for normal consumption and is one community's odd nod to the fight against global warming. The community's leaders hope to erect more panels and triple the electricity output. Before this, the town had four other solar parks -- atop buildings and such -- but the cemetery is by far the biggest. Read more here.
Hybrid Cars Could Store Energy for the Grid
Scientists at the University of Michigan are rethinking the role of electric cars in the future. What if, instead of sucking up resources, those cars could serve as storage for alternative energy, and put that energy onto the grid when it's most needed? The "vehicle-to-grid integration" idea is one that could help stabilize the grid, and reduce the need to build more power plants. The basic idea is to use the batteries in plug-in electric hybrid vehicles as extra storage space for grid energy, such as energy from renewable resources like sun and wind. Read more here .
How About Some Optimism For a Change?
Here is what the future may hold if roadmaps, predictions and policy targets all come true.
2010: 5.2 percent reduction in greenhouse gas emissions emissions from 1990 levels is achieved by those countries that signed the Kyoto Protocol. 20 percent of California's electricity comes from renewables. Toyota releases a plug-in hybrid electric vehicle.
2018: 100 percent of U.S. electricity comes from solar, wind and other renewables (Gore's prediction). $255 billion spent per year (more than four times what is currently spent) on biofuels, wind power, solar photovoltaics, and hydrogen fuel cells. $150 billion invested by this date by the U.S. government on climate-friendly energy development (Obama's plan).

Flying Electric Generators?
According to Skywindpower.com, the energy in the high altitude winds is more than enough to meet the world's energy needs, it is non global warming, and the means of capturing this energy are available through a little further development of technologies that do not require any fundamental scientific breakthroughs. Truly high energy winds are at altitudes miles above us, not just at a few hundred feet where they can be tapped by rotors on towers. The total swept area for a Flying Electric Generator of the same megawatt rating as a ground based wind turbine is typically about a quarter as much. Yet the Flying Electric Generator would produce far more megawatt hours of electricity per year due to the much higher high altitude wind speeds and constancy. Read More.
Spray On Solar Cells
An inch-long array of some of the tiniest solar cells ever built has been successfully tested as a power source for microscopic machines, a new study reports. Instead of using silicon, Xiaomei Jiang and her colleagues from the University of South Florida turned to a polymer (a long organic molecule made of repeating structural units). The polymer they selected has the same electrical properties as silicon wafers, but can be dissolved and printed onto flexible material. Jiang and her colleagues made 20 tiny cells - each the size of a lower case "o" in standard 12-point print - and joined them together in an array to power a microscopic chemical detector.

Solar Roadways Could Do It All!
The Solar Roadway™ is a series of interconnected Solar Road Panels™ that you actually drive on. The idea is to replace all current asphalt roads, parking lots, and driveways with Solar Road Panels™ that collect and store solar energy to be used by our homes and businesses. When multiple Solar Road Panels™ are interconnected, the Solar Roadway™ is formed. These panels replace current driveways, parking lots, and all road systems, be they interstate highways, state routes, downtown streets, residential streets, or even plain dirt or gravel country roads. Panels can also be used in amusement parks, raceways, bike paths, parking garage rooftops, remote military locations, etc. Any home or business connected to the Solar Roadway™ (via a Solar Road Panel™ driveway or parking lot) receives the power and data signals that the Solar Roadway™ provides. Here is a youtube presentation and there is lots more info on the SolarRoadway website .
Energy Islands Power the Future
The ocean harbors abundant energy in the form of wind, waves and sun. All of these could be sampled on something called an Energy Island: a floating rig that drills for renewables instead of petroleum. The Energy Island would have an OTEC (ocean thermal energy conversion) plant at its center, but spread across the 2,000-foot-wide (600-meter-wide) platform would also be wind turbines and solar collectors. Additionally, wave energy converters and sea current turbines would capture energy from water moving around the structure. One of these hexagonally-shaped islands could generate 250 megawatts.

Turning Pond Scum Into High-octane Gasoline
At a time when U.S. gasoline prices were arcing beyond $4 a gallon nationwide, Sapphire Energy said it had proven the feasibility of using algae to make "green crude" that can serve as an identical substitute for crude oil. Sapphire said its product, unlike other biofuels, could enter the pipeline at any petroleum refinery for processing into gasoline and other fuels. Sapphire's process has been used successfully to make the three most important fuels, gasoline, diesel, and jet fuel, and all three products have been independently certified to meet fuel standards set by the American Society for Testing and Materials. Sapphire's concept calls for creating enormous algae "farms" throughout the desert lands of the southwestern United States. Read more here.
