AB 32’s Scoping Plan is a Tale of Two Energy Futures

By Tim O'Connor / Published: August 14, 2013

This commentary originally appeared on EDF’s California Dream 2.0 blog.

For a window into two vastly different visions of our state’s future, take a look at the comments filed last week as part of the AB 32 Scoping Plan update process. The 2008 Scoping Plan lays out the approach that California will take to achieve its goal of reducing emissions to 1990 levels by 2020, and this is the first 5 year update.

EDF’s comments reflect what most Californians have already asked for – a laser focus on expanding emission reductions and providing ample clean energy opportunities for businesses throughout the state.

This includes:

Increasing emission reductions from vehicles, goods movement and the agriculture sector;
Developing diversified low-carbon fuels that yield cost reductions;
Integrating clean energy and energy efficiency through programs like “time-of-use” pricing and On-Bill Repayment;
And, extending the cap-and-trade program and low carbon fuel standard beyond 2020;

All of the opportunities outlined by EDF aim to fulfill the Scoping Plan’s mission: achieving the maximum technologically feasible reductions in greenhouse gas pollution in a cost-effective way.

Good News On Clean Air To Beat The August Doldrums

By Tomas Carbonell / Published: August 13, 2013

August is typically a quiet time of year, and particularly so for work that concerns the nation’s capital. But amidst the dog days of summer, federal regulators made a fairly significant move this month to preserve stricter emissions controls for thousands of large storage vessels used to temporarily house crude oil, condensate and other liquids.

Last Monday, the U.S. Environmental Protection Agency (EPA) issued a rule that keeps in place an important aspect of its oil and gas pollution standards (or New Source Performance Standards, NSPS) issued last year, including provisions for storage tanks that emit six or more tons of ozone-forming air pollutants annually. These standards were intended to help reduce ground-level ozone and methane emissions in areas where oil and gas production occur. EPA proposed revisions to these standards in April of 2013 in response to industry petitions for less stringent requirements that would have considerably diminished important gains made by the NSPS to protect public health and the environment. EDF and five other environmental organizations joined together to strongly encourage EPA’s reconsideration, opposing these revisions in detailed technical comments filed with the agency.

EPA’s final rule is good news in the fight for cleaner, healthier air. Whereas the April 2013 proposal would have created a broad exemption from emission controls for thousands of recently-built tanks, the final rule ensures that operators of all new storage tanks that pass the six ton threshold will be required to reduce emissions by 95 percent. Controlling emissions from oil and gas storage tanks is important. Roughly 20,000 newly constructed tanks have been added in the field since August 2011 and these receptacles, if not properly managed, could be a large source of ozone forming pollution, as well as climate altering methane emissions. Had EPA proceeded to establish a broad exemption for these tanks, millions of tons of additional ozone-forming pollution and hundreds of thousands of tons of methane would have been released into the atmosphere.

Big-Box Retailers Turn To Solar, How Can Electric Utilities Adapt?

By John Finnigan / Published: August 9, 2013

The electric utility industry faces the risk of declining revenues as more customers install solar panels on their homes and businesses. Solar power currently supplies 2% of the country’s electricity needs, and is projected to grow to 16% by 2020. In 2013, solar panel prices for commercial installations fell 15.6%, from $4.64/watt to $3.92/watt. To protect their revenues, some utilities are raising electricity costs for solar panel owners – but with mixed results. Credit ratings agencies are also expressing concern. Is there real cause for alarm or are these companies crying wolf? Judging by one customer segment – big-box retailers – the threat is real.

The Solar Energy Industries Association (SEIA) ranks U.S. companies based on their solar energy capacity, and the top five companies on the list are big-box retailers:

Walmart tops SEIA’s list with 65,000 kW of solar power, which is enough to supply the annual energy needs of over 10,000 homes. They recently installed ten new solar rooftop systems in Maryland, totaling more than 13,000 panels. Walmart is the largest retailer in the U.S. and in the world by revenue, with 4,423 U.S. stores and over 10,000 stores worldwide. Walmart and EDF have been working together since 2004 to reduce the Walmart’s environmental footprint. With more than 200 solar installations across the country, Walmart plans to have 1,000 solar installations by 2020. Walmart’s goal is to eventually supply 100% of its energy needs with renewable energy.

Is The Glass Half Full Or Half Empty For Solar Power?

By Jackie Roberts / Published: August 8, 2013

GE and First Solar announced earlier this week an important step towards consolidation of the solar industry that will result in the loss of a new solar manufacturing facility in Colorado and, potentially 350 jobs. Clearly the announcement is frustrating for Colorado, a state we featured in EDF’s Clean Energy Economic Development Series, which highlights key road maps for maximizing economic development from clean energy markets.

But, the announcement includes lots of good news – which is probably more significant for the U.S.’s long-term solar power play as well as overall economic opportunity and job creation. In 2009, GE purchased PrimeStar Solar, a company first seeded at the Department of Energy’s National Renewable Energy Labs (NREL), located in Colorado. PrimeStar Solar (renamed Arvada research center) made significant advances in the efficiency of cadmium-telluride (CdTe) thin film solar panels. This lowered the cost of thin film solar panels overall and made them more competitive with traditional solar panels.

CdTe thin film solar panels require less material than alternative technologies – which lowers their cost – but their efficiency continues to lag behind traditional, silicon-based solar panels. The deal gives GE a large stock position in First Solar in exchange for giving First Solar the new CdTe thin film solar technology – essentially creating a key strategic partnership between the two companies.

Energy And Water Are Running Out In Texas, But It’s Not Too Late

By Kate Zerrenner / Published: August 8, 2013

As we’ve highlighted in previous posts, water and energy regulators often make decisions in silos, despite the inherent connection between these two sectors. Texas is no exception.

Two very important and intertwined events are happening in Texas right now.

First, the state is in the midst of an energy crunch brought on by a dysfunctional electricity market, drought, population growth and extreme summer temperatures. An energy crunch signifies that the available supply of power barely exceeds the projected need (or demand) for electricity. Texas’ insufficient power supply makes the whole electricity system vulnerable to extreme weather events. An especially hot day (with thousands of air conditioning units running at full blast) could push the state over the edge and force the Electric Reliability Council of Texas (ERCOT), the institution charged with ensuring grid reliability, to issue rolling blackouts.

Second, Texas is still in the midst of a severe, multi-year drought, forcing state agencies to impose strict water restrictions throughout the state. The drought has already had a devastating impact on surface water and many communities are facing critical water shortages.

Although Texas has always had to deal with extreme weather events, we can anticipate even more intense weather as climate change advances. The new climate ‘normal’ makes extreme heat waves, like the historic 2011 Texas summer, 20 times more likely to occur. These extreme weather events heighten the urgency of the energy-water nexus.

New DOE Effort To Standardize The Energy Efficiency Data Dictionary

By EDF Blogs / Published: August 8, 2013

By: Matt Golden, Senior Energy Finance Consultant, Environmental Defense Fund

This week, the U.S. Department of Energy (DOE) released a new report that will serve as a data analysis tool for the energy performance of commercial and residential buildings. By providing a standardized approach for the evaluation of energy data, the Building Energy Data Exchange Specification (BEDES) will help optimize energy efficiency efforts.

BEDES provides a common language for key data elements to help a range of stakeholders communicate more effectively. The use of established formats, terms and definitions will allow for smoother interaction between contractors, software vendors, finance companies, utilities, and Public Utility Commissions. As a result, information can be shared and aggregated without laborious scrubbing and translation, which will help more rapidly answer the key questions related to energy savings and financial performance that remain barriers to energy efficiency adoption at scale.

We are pleased that the Investor Confidence Project (ICP) was highlighted as one of five key projects aligned with BEDES goals, and prioritized for collaboration as the project moves forward. The Executive Summary (page 4) of the report clearly expresses some of the key data issues and potential solutions that this ambitious project will attempt to solve.
