The first time that I rode on San Francisco’s Muni it cost me a quarter, complete with a two hour unlimited transfer. Even as a clueless adolescent, I thought that was a pretty good deal. Mass transit ridership is skyrocketing all over the country, as more and more people are utilizing more sustainable methods of transport and

More people than ever are now using mass transit in the United States. Ridership on trains, buses, ferries and subways is at record levels, according to a survey just released by the American Public Transportation Association. Their study reports that, “despite falling gas prices and an economic recession, increasing numbers of Americans took 10.7 billion trips on public transportation in 2008, the highest level of ridership in 52 years and a modern ridership record”, and a 4% increase from [...]

According to a new study conducted by the Lawrence Berkeley National Laboratory, The average installed costs for photovoltaic cells (in real 2007 dollars) went down from $10.50-per-watt in 1998, to $7.60-per-watt in 2007.

What’s most amazing about this report is that it appears to validate a whole slew of state and local solar initiatives. The researchers found that—despite the many, many reported advances to solar cell efficiency—most of the savings during this nine year period came from reductions to installation and external hardware costs.

Sun Well Solar—a subsidiary of the notoriously poor CD and DVD manufacturer, CMC Magnetics—has announced today that it is one month ahead of schedule in the ramp-up of its new photovoltaic production line.

Solar PV manufacturer Oerlikon Solar has pioneered a new thin film solar technology process, which it claims has made its solar cells 7 per cent efficient - a 16 per cent energy improvement over its previous technology. The advance has led to a 50 per cent increase in the capacity of its thin film solar fabrication plant.

So, why is this important? Well, thin film cells are typically a lot cheaper to produce than more common silicon solar cells, but often suffer from significantly lower conversion efficiencies. Oerlikon’s breakthrough moves us a lot closer to the day when thin film becomes more cost-effective than silicon-based panels - which could mean a dramatic rise in the adoption of solar power in homes and businesses.

The Solar Electric Power Association (SEPA) has outlined four easy steps to a thirty fold increase in the size of the US solar power industry between 2009 and 2016, leading to over $230 billion worth of investment and the creation of 440,000 permanent jobs.
