Looking to the States to Improve Natural Gas Storage Policies

By Adam Peltz / Published: February 21, 2017

Stories about gas storage rarely make headlines, but the fact is there are hundreds of underground natural gas storage facilities peppered across the country, and when something goes wrong, the impacts can be devastating. For example, in 2015 a leak at the Aliso Canyon storage facility in Southern California ended up displacing thousands from their homes and was considered one of the biggest environmental disasters in modern U.S. history.

Historically, state agencies have been responsible for regulating these facilities – resulting in a patchwork of protections. But after Aliso Canyon, the federal government stepped in to provide uniform safety standards applicable across the country. Read More »

New Study Highlights Need for California Market Refinements to Better Harness Clean Energy

By Simi George / Published: February 21, 2017

A new study, jointly conducted by the California Independent System Operator (CAISO) – the entity responsible for overseeing much of California’s electric grid – First Solar, and the National Renewable Energy Laboratory (NREL), demonstrates the untapped potential of utility-scale solar. The study shows that utility-scale solar can provide key services needed to ensure electric grid stability and reliability – better known as ancillary services – at levels comparable to conventional, fossil fuel driven resources.

California needs to reduce reliance on natural gas for ancillary services

In CAISO’s market, ancillary services are overwhelmingly provided by natural gas-fired resources, and their share of the pie has been increasing in recent years.

This growing reliance on natural gas for ancillary services merits attention for many reasons.   Read More »

EPA’s Greenhouse Gas Inventory Makes Progress but Misses Forest for Trees

By David Lyon / Published: February 15, 2017

In its draft 2017 GHG inventory, published this week, the EPA estimates methane emissions from the oil and gas industry were lower than their previous estimate in the 2016 inventory.

The vast majority of the decrease comes from methodological changes in how EPA does these estimates and does not represent actual reductions from improved industry practices. We expect to see fluctuation in EPA estimates in future inventories as the agency continues to revise their accounting methods; this inventory should not be viewed as the final answer. But, to see the actual trend in emissions, you should compare 2015 emissions to their updated estimate of 2014 emissions, not the estimate from last year’s inventory. EPA estimates a mere 2% reduction in actual emissions, largely attributable to reduced drilling activity and well completions, which is a result of lower oil and gas prices in 2015. This points to the importance of recently enacted regulations, like the EPA NSPS and BLM rule, to drive the much greater reductions needed to minimize waste and the climate impacts of oil and gas.

Saving Energy and Doubling Worldwide Water Supplies – One Drip at a Time

By Kate Zerrenner / Published: February 9, 2017

Netafim HQOn a warm December day, I stood in a jojoba field in the Negev Desert in southern Israel and watched water slowly seep up from the ground around the trees. First a tiny spot, then spreading, watering the plants from deep below. This highly efficient system is known as drip irrigation, and I was there to meet with the world’s leading drip irrigation company, Israel-based Netafim.

Naty Barak, the Netafim director who I met on the visit, notes that if the world’s farmers increased their use of drip irrigation to 15 percent (up from just under 5 percent now), the amount of water available for use worldwide could double.

Drip irrigation saves more than water. Whereas traditional irrigation typically uses quite a bit of energy, drip reduces the pressure (and power) needed to get the water to the crops while reducing the need for energy-hungry fertilizers. Plus, due to the inextricable link between water and power, saving water results in further saved energy.

Texas has already enhanced its water efficiency, but it could go further and take a page out of Israel’s book. By investing in thoughtful drip irrigation now, Texas could lead the nation on expanding this innovative technology and significantly reduce the energy footprint of its irrigation sector, while protecting water supplies for our growing cities and creating more sustainable farming practices.

Congressional Review Act: A Law of Unintended and Long-Lasting Consequences

By EDF Blogs / Published: February 9, 2017

With legislation flying fast and furious through the Capitol – much of it using new or unusual legal mechanisms – lawmakers today must be doubly mindful of unintended consequences. Case in point: Actions rushed through the House and Senate under an obscure law called the Congressional Review Act (CRA), the details of which can cause deeper, more lasting impact than the simple name implies.

The CRA dates to the 1990s. It says that any rule finalized by a federal agency can be subject to an expedited congressional repeal for 60 legislative days after the agency sends up a copy of the final rule and a report detailing the reasons for its promulgation. Within that window, either chamber can introduce a joint resolution of disapproval – which, if passed by both houses of Congress and signed by the president, effectively voids the rule.

The law sounds simple enough. But it leaves a lot of room for error or mischief. Read More »

Texas Leaders Can Use Clean Energy to Increase Investments and Create Jobs. Here’s How.

By John Hall / Published: February 8, 2017

GA_Washington_DC4It’s that time again. Texas leaders are meeting in Austin for the 85th Legislative Session and the next five months will be an interesting wrestling match over human rights, voting rights, bathroom rights, and local rights.

But what about our economic rights? A new report Environmental Defense Fund (EDF) issued to the Texas Legislature, Texas’ Clean Energy Economy: Prioritizing Jobs, Investments, and Growth, shows the Lone Star State’s evolving electricity landscape has created enormous economic growth and jobs. The report explores the policies put in place years ago that has allowed Texas’ power market to become cleaner and more affordable, and it outlines the state’s impressive job growth in energy efficiency, wind, and solar power.

The report urges our leaders to develop and implement a bold, comprehensive Texas energy plan to create well-paid jobs, drive innovation and investment, make us more energy independent, and protect our water supplies, while improving the health of Texans and the environment. Read More »
