Hydro fracturing is a profitable method of natural gas extraction that uses large quantities of water and chemicals to free gas from underground rock formations. But New York City’s concerns that the practice would threaten its water supply have slowed a juggernaut that has been sweeping across parts of the northeastern United States.

The highly productive method of natural gas extraction known as “hydro fracturing” has spread rapidly across the United States in recent years, opening up vast new reserves in Texas, Wyoming, Pennsylvania, and other states.

Last fall, however, the process — also known as “fracking” — ran headlong into opposition from New York City. And for now at least, stiff resistance from the city, which fears the contamination of its pristine water supply in upstate New York, seems to have slowed the momentum behind this highly touted — and highly controversial — drilling technique.

Where Have the Plastic Bags Gone?

written by Environmental News Network

Plastic bags are everywhere. Many years ago the only bags at the grocery store were paper ones. Now you have a choice of paper, plastic or bring your bag. Where have all the bags gone after they are used? Plastic bag and film recycling in the U.S. reached a record high in 2008, recovering about 832 million pounds of post consumer film, according to a new study from the American Chemistry Council.

Plastic bags are difficult and costly to recycle and many end up on landfill sites where they take around 300 years to photo degrade. They break down into tiny toxic particles that contaminate the soil and waterways and enter the food chain when animals accidentally ingest them. But the problems surrounding waste plastic bags starts long before they photo degrade. Many become airborne and float surprising distances. Others can choke waterways and animals.

The “National Post-Consumer Recycled Plastic Bags and Film Report,” conducted by Moore Recycling Associates, finds that plastic bag and film recovery increased 28 percent since 2005, driven by several factors including greater consumer access to collection programs and new markets for the recycled materials such as backyard decking, fencing, railings, shopping carts and new bags.

Aviation Industry Hangs Its Future on Biofuels

written by Mackinnon Lawrence

Aviation demand for biofuels is bursting at the seams. Hemmed in by emerging certifications, a petroleum-based distribution network, and lack of supply, the industry is stuck on petroleum fuels for now, but not by choice.

Pressure to integrate more biofuels into the supply chain is palpable: oil price increases, oil price volatility, oil scarcity, greenhouse gas emission regulation, and increasingly, corporate social responsibility commitments. The future of the aviation sector is dependent on its ability to pivot away from petroleum-based fuels to alternative sources of energy, and they must do it quickly.

One caveat: while demand may be substantial, no one knows for sure if supply can keep pace, which makes statements from aviation experts at the World Biofuels Markets taking place in Amsterdam this week all that more interesting.

Fuel Prices At $20 Per Gallon — Sustainable? Impossible? Profitable?

written by Joe Walsh

NPR’s On Point never disappoints, and their show with Christopher Steiner, author of $20 Per Gallon: How the Inevitable Rise in the Price of Gasoline Will Change Our Lives for the Better was no exception. Steiner’s thesis is that as liquid hydrocarbons become all the more difficult to naturally extract and regulation makes them all the more costly to refine and use, prices will inevitably rise. At $20 a gallon, we might not recognize our lives…all for the better, says Steiner.

People will live and buy their locally-grown produce in mixed-use developments clustered around high-speed rail lines. In Steiner’s view, $6 a gallon is an inflection point that begins to redefine the way we live our lives. But, will innovation (or the US government) ever allow prices to remain at that level? Not according to Mark Mills, co-author of The Bottomless Well: The Twilight of Fuel, the Virtue of Waste, and Why We Will Never Run Out of Energy.

Clean Energy Policy Debate: Let’s Agree to Agree!

written by Joe Walsh

Anyone watching the health care debate spread from Capitol Hill conference rooms to town halls nationwide knows that everyone agrees we need health care reform. The disagreement comes in determining what kind. Comprehensive tort reform fits under the heading and so would the implementation of a single-payer system, but the two solutions could not be much farther apart on the political spectrum. An apt analogy – as the summer vacation season comes to a close – may be the good old fashioned American road trip: the whole family knows the destination, but getting there is the tough part.

Wait a cotton-picking minute, and listen to BioSolar’s plans

written by Jeff Kart

BioSolar Inc., a publicly traded California company, says it’s come up with a way to build a better solar panel, with plastics made from plants.

I sat down recently with company CEO David Lee, both of us at keyboards, to discuss BioSolar’s plans for a plastic revolution in sun power manufacturing.

Lee’s protective backing is derived from cotton and castor beans, and costs 25 percent less than Tedlar, the petroleum-based film made by rival DuPont, company officials say. Lee, an electrical engineer, founded the company in 2006.

Q: What makes BioSolar different from other solar companies in the United States?

Lee: BioSolar is developing a technology to produce bio-based photovoltaic (PV) components from renewable plant sources that will reduce the cost per watt of PV modules. BioSolar will gradually replace the petroleum-based portions of the PV module and do so at a substantial cost savings.
