Science and Economics Agree: The Time is Right for California to Get Serious About Methane Pollution

Larissa-Koehler-200x300Recent numbers from the Intergovernmental Panel on Climate Change (IPCC) show that methane (CH4) is about 80 times more potent than carbon dioxide (CO2) in contributing to climate change over the first 20 years after it is released. Short-lived climate pollutants, like methane, are a large factor in determining how fast our climate will change over the next few decades.

These figures are particularly relevant in California where natural gas (which is about 99.9% methane) is used throughout the economy. For example, natural gas generates much of the state’s electricity through gas-fired power plants, is extensively used for home heating and cooking, and is increasingly being deployed as an alternative fuel for the state’s cars and trucks.

Yet, while California continues to operate and further build out a natural gas backbone in its energy economy, venting and leakage of uncombusted natural gas from pipes and machines can have an environmental impact. In fact, research shows that keeping methane leakage down to a minimum level is the only way to guarantee that the use of natural gas will provide immediate climate benefits, when switching from petroleum products.

Changing Times for Electric Utilities

Two seemingly unrelated announcements drew much attention in the electric utility industry recently. First, the Edison Electric Institute (EEI) (the trade group for the U.S. electric utility industry) and the Natural Resources Defense Council (NRDC) jointly recommended changing how utilities should be regulated. Second, Duke Energy announced it will sell 13 Midwest merchant power plants. These announcements are actually related because they both result from the same dramatic changes affecting the electric utility industry. As Bob Dylan aptly noted, “the times they are a-changin’.” Regulators and other stakeholders must be prepared to address these changes.

Under the traditional business model, electricity usage grew steadily. Utilities built ever-larger plants to serve this growing load. The bigger plants were more efficient than existing plants, so the unit cost for electricity steadily declined. Utilities benefited by steadily increasing their revenues. Customers benefited from declining unit costs. For utility customers, it was like paying a lower price per gallon of gasoline every time you filled your tank.

But this traditional model is crumbling, due to several factors: Read More »

EDF Energy Innovation Series Feature: Treehouse’s One-Stop Shop for Solar

EDF’s Energy Innovation Series highlights innovations across a broad range of energy categories, including smart grid and renewable energy technologies, energy efficiency financing and progressive utilities, to name a few. This Series helps illustrate that cost-effective, clean energy solutions are available now and imperative to lowering our dependence on fossil fuels.

Find more information on this featured innovation here.

Few people walk into a car dealership and ask to see all of the 2.0 liter engines or only the 200 horsepower cars. Those technical specs are important, but most people shop by model, price or features.

Yet homeowners that want to install solar panels often find themselves buried in a mound of technical details that are not only confusing, but intimidating. And expensive. Austin-based sustainable living retailer Treehouse is changing that and proving that energy innovation is sometimes less about technology and policy and more about thinking like customers.

“The solar industry has done a great job educating people about the benefits of solar energy,” said Treehouse founder and president Jason Ballard. “But it’s done a bad job of making solar easy to buy.” Read More »

Keeping It Clean: California Should Use Clean Resources To Integrate Renewables

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

As the 8th largest economy in the world, California remains a global leader in clean tech investment, innovation and adoption of landmark climate and energy policies. What defines our success?  Our ability to try things first, set the bar high, and get policies right.

California’s Renewable Portfolio Standard (RPS) is a perfect example of that bold, pioneering spirit. Passed in 2011, the RPS required that 33% of electricity come from renewables by 2020 – a lofty benchmark, even by California’s standards. Along with self-generation and solar rooftop programs, California is successfully adding solar, wind, and other distributed generation to its resource portfolio.

In fact, renewables are successfully becoming a large part of daytime energy production, the California Independent Systems Operator (CAISO) – the organization in charge of balancing the statewide grid – is concerned over how to make up for that energy when the sun goes down while evening energy demand spikes.  The question is: How can the CAISO reliably integrate renewables?

The CAISO is currently figuring out how to address this need for “flexible” power and will have a draft decision out on October 2nd.  Just like people prefer to take routes they know well when they drive, the CAISO is most comfortable with what they know: familiar fossil fuels. Using clean resources and demand response instead is new territory for them that will require careful orienteering.

Austin Energy + Nest: Empowering Texans To Take Control Over Their Own Energy Use And Electric Bills

Source: Nest

If you have been following our Texas Energy Crunch campaign over the last year, you know that demand response (DR) can play a pivotal role in meeting Texas’ energy needs without relying on dirty, inefficient fossil fuels that pollute our air and consume much-needed water.  Simply put, demand response rewards those who reduce electricity use during peak (high energy demand) times, resulting in more money in peoples’ pockets, a more stable and reliable electric grid and less harmful pollution from fossil fuel-fired power plants.

That said, fully harnessing DR in Texas homes has been a bit of a challenge, despite the high electricity prices that result from the scorching summer temperatures.  To understand the issue, it’s important to look at the obstacles emerging technologies often face.  I highlight some of these obstacles in a recent EDF Voices blog and will be diving deeper in future posts.  Namely, the infrastructure to fully enable residential DR adoption isn’t in place, yet.

House Cuts Clean Energy Funding, Dragging Down An Entire Community Of American Innovators

This commentary, authored by Robert Fares, originally appeared on Scientific American’s “Plugged In” blog.

The U.S. Department of Energy recently partnered with Texas Tech University to commission a Scaled Wind Farm Technology (SwiFT) laboratory, which helps researchers understand how wind turbine placement affects performance. (Source: Texas Tech University)

In my last post, I discussed a House subcommittee’s shortsighted vote to slash funding for the U.S. Department of Energy’s (DOE’s) innovative Advanced Research Projects Agency – Energy (ARPA-E). I’m sorry to report that the rest of the House has now followed suit, passing a $30 billion energy spending bill that cuts a huge chunk out of clean energy programs.

Not only does the bill contain the subcommittee’s 81 percent cut to ARPA-E, it also guts energy efficiency programs and even rolls back progress in energy efficient lighting. The House’s embargo on funding for clean energy doesn’t just hurt our footing in the international race towards a new energy economy, it also drags down an entire community of American innovators working to achieve a sustainable future.

We deserve more than political posturing and moves as antiquated as the incandescent bulb. Right now, a convergence of environmental, economic and technological forces is transforming the global energy landscape. Just last month, the International Energy Agency (IEA) projected that renewable energy sources would eclipse nuclear and gas generation by 2016, and provide a quarter of the world’s energy supply by 2018. Renewable energy is unequivocally a major component of the energy landscape. Read More »
