Basically, Pigouvian taxes would tax the things we do not want in our society, like toxins and greenhouse gases, and NOT tax things we like in society, like employment and housing. For example, when coal power plants emit traces of mercury, we should not tax the power produced, but the harmful mercury emitted.
With a total of 90 special events held throughout the U.S. and Canada, National AFV Day Odyssey events served as a voice to deliver the message about the importance of alternative fuel and advanced technology vehicles to a populace feeling the crunch of higher pump prices and worrying about the impacts of traditional fuel sources on the environment.
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.
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 .
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.
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.
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 .
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).

Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGrip™ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
