Big Rigs: Will the Climate Benefit from Switching Diesel Trucks to Natural Gas?

By EDF Blogs / Published: May 19, 2015

By: Jonathan Camuzeaux, Senior Economic Analyst

16058670001_80994ae935_z The surge in natural gas production that has reshaped the American energy landscape has many in the commercial transportation sector considering whether to start shifting their heavy-duty vehicle fleets from diesel to natural gas fuel. Many are looking to an advantage in carbon dioxide emissions to justify the higher cost and reduced fuel efficiency of a natural gas vehicle.

But in fact, a study published today in Environmental Science & Technology finds that while there are pathways for natural gas trucks to achieve climate benefits, reductions in potent heat trapping methane emissions across the natural gas value chain are necessary, along with engine efficiency improvements. If these steps are not taken, switching truck fleets from diesel to natural gas could actually increase warming for decades.

Methane, the main ingredient in natural gas, has 84 times more warming power than CO₂ over a 20-year timeframe. Reducing emissions throughout the natural gas value chain is an important opportunity to reduce our overall greenhouse footprint. Read More »

Want to See EDF at SXSW Eco 2015? Cast Your Vote!

By EDF Blogs / Published: May 18, 2015

Every year, SXSW Eco – one of the most high-profile environmental conferences – selects its programming based on votes from the public. This means anyone, regardless of whether you submitted a panel, can cast a vote.

This year, seven experts from Environmental Defense Fund are featured on dynamic panels that cover everything from solar equity and new utility business models to innovative building efficiency programs and the threat of methane pollution. To make sure EDF and energy-related programming is represented at the conference in Austin, TX this October, we are asking our readers to please vote for your favorite EDF panels and presentations.

Under the Wire: EDF Welcomes SoCalGas Leak Maps

By Tim O'Connor / Published: May 15, 2015

A great thing happened today for the environment and people of California. On the very day we released new maps measuring methane leaking from natural gas lines under Los Angeles-area streets, the Southern California Gas Company (SoCalGas) announced they would begin publishing their own maps showing the locations of leaks they find on their system.

It is a positive move that brings the company a big step closer to complying with the California law requiring them to publish not only the whereabouts of known leaks, but also the amount of methane escaping (which their newly announced maps do not). The public has a right to know where and how much harmful air pollution is being emitted by SoCalGas and any other company in California.

Adding to the Clean Energy Chorus: Voices of Faith

By Marilynn Marsh-Robinson / Published: May 14, 2015

Diverse groups are creating a healthy dialogue on climate change and clean energy. In addition to ethnicity, diversity includes geographical representation, political affiliation, socio-economic backgrounds – and religious beliefs.

One notable group, Interfaith Power and Light (IPL), is mobilizing millions of people of faith to be better stewards of energy and the environment. Founded in 1998, IPL now has chapters in more than 40 states and represents 15,000 congregations. IPL works with congregations to promote energy conservation, energy efficiency, and renewable energy, with the goal of reducing carbon emissions and the impacts of climate change.

In addition to clean energy advocacy, IPL recognizes that public policies – local, state and federal – play a pivotal role in reducing reliance on fossil fuels and expanding energy choices. IPL rightly focuses attention on communities most vulnerable to the impacts of climate change, advocating for strong adaptation and mitigation actions to protect all communities – from the coast to the heartland. These communities, which are least responsible for activities and decisions that adversely impact the climate, suffer the most. Read More »

FirstEnergy Will Raise Rates to Recoup Bad Bets on Coal

By Dick Munson / Published: May 13, 2015

FirstEnergy, the giant Ohio-based company that owns power plants and transmission lines in several midwestern and northeastern states, is ready to raise electricity prices for its customers. This is in part because three of its oldest coal-fired power plants are set to close, but also because of a few bad business bets.

Though finally shuttered this week, the three plant closures were announced in January 2012 so FirstEnergy could take advantage of a power auction planned by PJM Interconnection, the power grid operator in the Mid-Atlantic region. That auction determines the most efficient power plants to serve this region for the next three years.

By taking these old and dirty units out of the auction, FirstEnergy was able to push up prices for its other power plants.

At the time, environmentalists argued FirstEnergy should account for the efficiency gains that would result from state-mandated programs. Lower demand for electricity caused by efficiency improvements would have reduced the auction price for power. Although such energy efficiency is typically “bid” into PJM auctions in the same way coal or nuclear energy is, FirstEnergy refused. Read More »

Smart Energy Policy Deserves Advanced Meters

By Beia Spiller / Published: May 13, 2015

With time-variant pricing, people can choose to run their dishwashers at times of day when electricity is less expensive.

New York cemented its reputation as a national leader in energy policy last year when it announced plans to revamp the way utilities are regulated in order to establish a 21st-century energy system. But the state is still trailing in one crucial area: More than 99% of its homes have antiquated meters that tell utilities nothing more than how much electricity customers use each month. To achieve its ambitious goal of an energy revolution, the state should embrace a technology—advanced meters—that empowers New Yorkers to cut their energy use during times of the day when it matters most.

A key component of the smart grid, advanced meters provide detailed electricity-use data throughout the day. This information reduces inefficiencies in the energy system and leads to quicker detection of power outages. Such improvements reduce the costs of operating the power grid, resulting in lower electricity prices.

Advanced meters, also known as two-way-communicating Advanced Metering Infrastructure (AMI), or “smart meters” (which can both send and receive information such as electricity prices and energy usage), enable pricing that incentivizes customers to use electricity when it is cheaper and cut back when it is expensive. This time-variant pricing reduces congestion on the power grid, ultimately lowering costs for everybody. But, without advanced meters measuring electricity use in short time intervals, it’s impossible for utilities to bill on a time-variant basis. Read More »
