These days, the future is often in the news. It’s not uncommon to come upon articles about cars that drive themselves, vacation trips to space, and automated smart houses a la the Jetsons.

I don’t know much about space tourism or self-driving cars, but I do know that smart homes and the associated technologies are already allowing for the possibility of environmental benefits and economic savings that are nothing short of futuristic.

Our utility grid is the largest machine in world. Unfortunately, however, this machine exacts human and environmental costs all the way down the line — from extraction to combustion. But we’re at the beginning of an energy revolution in home energy management systems that may make consumers key players in solving these problems.

U.S. Electric Grid Under Cyber-Attack

By John Finnigan / Published: August 20, 2013

If Ben Franklin lived today, he might say that nothing is certain but death, taxes and cyber-attacks. Cyber-attacks occur when individuals or groups hack into another group’s computer information systems to steal, alter or damage key infrastructure. Our nation’s electric grid is under constant attack according to a survey of electric utilities by U.S. House Representatives Henry Waxman and (now) Senator Edward Markey. The grid was the greatest engineering achievement of the 20^th Century, but cybersecurity was equally unknown to those grid engineers as it was to Ben Franklin. We need to do more to protect our energy infrastructure.

The U.S. has finally called out China for repeated and pervasive cyber-attacks. Mandiant, a cybersecurity firm, released an alarming report in February 2013 regarding the ongoing cyber-attacks by the Chinese army. James Clapper, the Director of National Intelligence, described cyber-attacks as a soft war already underway and a dire global threat in his April 2013 World Threat Assessment to the U.S. House Permanent Select Committee on Intelligence. In May of this year, for the first time, the Pentagon’s annual report to Congress on the Chinese military openly accused China’s military of repeated cyber-attacks on the U.S. government and defense contractors.

Cyber-attacks are underway not only by China, but also by Iran, Russia, Al-Queda, organized crime, industrial spies, ex-utility employees and rogue hackers. The U.S. Department of Homeland Security investigated over 200 serious cyber-attacks against critical infrastructure during the first half of 2013. The electric grid was targeted in over half of these attacks. At the recent Black Hat security conference in Las Vegas, Cyrill Brunschwiler of Compass Security explained how the smart grid’s wireless network can be easily exploited to steal electricity and to cause massive blackouts. Though innovation and new clean energy technologies are key to modernizing our antiquated energy system, the electric grid is more vulnerable to cyber-attacks with increased use of smartphones, tablets, mobile apps and electric vehicles to connect with our home electronic devices. A July 2012 report by the Government Accountability Office (GAO) outlines the various threats to the electric grid.

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.
