In the aftermath of Superstorm Sandy, it’s still unclear whether consumers will see a nationwide gas spike.
One bit of good news: The Northeast’s largest refinery is coming back online. The Philadelphia Energy Solutions plant, which processes a third of the region’s oil, said it was “without issues.” Keep reading →
When one thinks of hybrids, cars like the Toyota Prius come to mind. There’s no reason though green vehicle technology like this needs to be limited to passenger cars or commercial vehicles like moving trucks. It is also turning up in the construction industry, in part via the unveiling in the last week of a new hybrid excavator from Caterpillar.
Caterpillar said its new Cat 336E H is a derivative of the company’s 336E large hydraulic excavator, which is described as a “recognized industry-leading workhorse” by its manufacturer. The new hybrid version is the company’s first to make use of what it calls “a novel hydraulic hybrid technology developed internally” that reportedly uses 25 percent less fuel compared to its regular sibling. Torque News noted of this machine that it has a drive train that “is a diesel-electric design but Caterpillar is not describing the electrical storage capacity nor power of the electric motor.” Keep reading →
Tuesday night, Obama championed his commitment to more oil and gas exploration, as well as reinforced the doubling of U.S. clean energy production under his leadership. And Romney, advocating our energy independence, solidified his strong commitment to drilling and promoting a surplus of oil and gas.
What I’d like to know, however, is their plans on the other side of the energy equation: the demand side. No matter how much new generation we bring to the table, energy independence just isn’t possible without curbing our exponentially rising need for electricity. And so far, neither candidate has pontificated on how to make this possible. Keep reading →
The Energy Efficient Buildings Hub, a public-private organization whose largest funder is the U.S. Department of Energy, is leading an ambitious charge to reduce energy consumption in Philadelphia’s commercial buildings. The hope is the model can be replicated in other cities across the US.
Because of the Hub’s efforts to “start moving the needle” on discussion of energy retrofits, the City of Philadelphia is likely to have a successful response to its new law requiring energy disclosure for large buildings, predicted Marla Thalheimer, Director of Sustainability at Liberty Property Trust, a commercial real estate firm and Hub partner.

Around 3,000 commercial building owners and contractors are weighing a new request for proposals on energy retrofits from an institution that’s a national leader in reducing energy consumption by existing buildings.
The Energy Efficient Buildings Hub, a public-private organization whose largest funder is the U.S. Department of Energy, sent out the RFPs on October 12 as the latest step toward fulfilling its ambitious goal of reducing energy use by commercial buildings in the Philadelphia region by 20 percent by 2020.

Touted by movie stars, discussed in presidential debates, solar and wind energy are the technological ‘it girls’ of our time. Meanwhile, combined heat and power, 100 years old and shaped like a box, can’t get a date with popular culture.
Such was the lament that threaded through last week’s annual gathering in Washington, D.C. of about 120 industry supporters of CHP, as the technology is more commonly known (for those who know it). Keep reading →
An effort by 22 U.S. states to spur demand for natural gas vehicles has produced a strong response from auto dealers to a request to supply CNG-powered cars, vans and trucks for state fleets.
Dealerships in 28 states representing the three big U.S. manufacturers plus Honda submitted more than 100 bids in response to a joint request for proposals by the states, which are seeking to boost demand for abundant domestic natural gas, and support the price after it fell to a decade-low in spring 2011.

Mining sand, clay and other industrial minerals for use by industrial concerns was a solid business for over 100 years, but the explosion of unconventional drilling that has helped boost US petroleum output to levels not seen in decades opened a new and lucrative market.
US Silica is a 112-year old company that got its start supplying sand to Pennsylvania’s glass industry, but around 2008 the firm began to supply proppants to companies that were hydraulic fracturing wells in order to tap liquid and gas hydrocarbons trapped in low-porosity geologic structures like shale.

We are currently living in a way that is indisputably unsustainable. The ecological resources on which modern housing depend are becoming increasingly scarce, and the excessive carbon footprint left behind by “McMansions” and sprawling suburban developments are leading more and more people to seek radically greener housing alternatives.
This is the second of a five-part series called “Off the Grid,” in which we explore environmentally-sustainable, self-sufficient communities across the globe. We’ll attempt to answer the question: Is green, off-grid living our future? This week, we take a look at an Earthship community in the deserts of New Mexico in the United States. Keep reading →
Natural gas is being taken more seriously as a transportation fuel by U.S. fleet operators and trucking companies, but its scarce availability is standing in the way of widespread adoption by the general public, industry experts said recently.
Despite the clear price advantage enjoyed by the relatively few car and truck drivers that use natural gas, it won’t become a significant source of transportation fuel until there’s a network of publicly available natural gas filling stations comparable to that for gasoline, or until home refueling is a viable option for most consumers, the experts said.
