Texas Boasts Most Modern Power Grid In The Country

By Marita Mirzatuny / Published: September 9, 2013

In an effort to gauge where America’s power grid stands, Washington D.C.-based group GridWise Alliance evaluated grid modernization in 41 states and the District of Columbia. Texas and California tied for first place—standing far above the next runner up.

So what makes Texas’ grid so special?

Texas restructured its electricity market in 1999, introducing competition into the retail electric market. The new competitive retail market gave most Texans a choice of electricity providers from dozens of companies, so these energy providers compete to offer the most advanced services. For example, Texans can opt for 100% renewable electricity from Green Mountain Energy.

Additionally, in an effort to update Texas’ electric grid, the Public Utility Commission, Texas’ governing body for electricity, passed a resolution prompting “wires companies”(the firms that deliver energy from power plants to homes and businesses) to invest in millions of smart meters. Smart meters can help eliminate huge waste in the energy system, reduce peak energy demand (rush hour on the electrical wires) and spur the adoption of clean, low-carbon energy resources, such as wind and solar power, by managing energy demand and generation more efficiently.

Local Energy-Water Solutions Should Be A Model For The Nation

By Kate Zerrenner / Published: September 5, 2013

Over the past several weeks, I’ve written a lot about the intimate and inextricable connection between energy and water. The energy-water nexus involves a number of technologies, environmental factors and stakeholders. Thus, it’s no surprise that water and energy’s fundamental connection has eluded policymakers for so long. With this post, I review the lessons discussed so far, so that policymakers can understand the key issues surrounding the energy-water nexus and what’s at stake if we fail to act now.

The Bottom Line

Conventional electricity sources, like coal, natural gas and nuclear power plants, require an abundance of water — about 190 billion gallons per day. Because the majority of our electricity comes from these sources, high energy use strains the water system and contributes to Texas’ prolonged drought. Coincidentally, extreme drought could force power plants to shut down.

Climate change is having a profound effect on our weather patterns, making extreme heat and drought more common in Texas and throughout the Southwest. If we don’t set the energy-water system on a sustainable course, we risk a compounded problem.

A Smart Approach To Smart Meters

By John Finnigan / Published: September 4, 2013

A new documentary about smart meters opens on September 5^th called Take Back Your Power. The film suggests that smart meters cause illness. According to an August 12 USA Today story, the film’s director was inspired by a friend who became seriously ill after a smart meter was installed at his home. Naturally, this type of personal experience might shape one’s view on smart meters, but correlation is not causation.

Electric utilities have installed over 38 million smart meters across the country and there “has never been a documented injury or health problem associated with such meters.” According to the Federal Communication Commission (FCC), “no scientific evidence establishes a causal link between wireless device use and cancer or other illnesses.”

Smart meters send information to utilities by using radio frequencies (RFs) such as those currently used by televisions, radios, baby monitors, cell phones and wifi routers. RF signals have permeated our atmosphere for as long as we’ve had televisions and radios.

We use these devices every day, and many of them create much higher levels of RF exposure than smart meters. The exposure level depends on the strength of the RF signal emitted by the device, the duration of the RF signal and—importantly— the distance from the source. Cell phones emit up to several thousand times more RF signals than smart meters. Smart meters also transmit intermittently and briefly during the day, while we talk on cell phones for long periods. Finally, smart meters are located outside the home, while cell phones are often used close to one’s head.

A Powerful Proposal To Increase Groundwater Knowledge In Wyoming

By Jon Goldstein / Published: September 3, 2013

Jon Goldstein The Latin phrase “Scientia potentia est” may not ring a bell, but its translation should: knowledge is power.

The oil and gas industry spends millions every year to expand its knowledge of underground energy reserves. That is because better geologic knowledge is powerful stuff, it can mean the difference between a very profitable well or a very expensive dry hole.

Doesn’t it make sense then for the industry to also invest in better knowledge of local water resources? Investing a small amount in understanding local groundwater quality before you drill, and following up to monitor whether that water is potentially impacted once energy production commences is also incredibly powerful for local residents, state regulators and the industry alike.

Wyoming oil and gas regulators have proposed a testing program that aims to do exactly this – establish a groundwater quality baseline in areas where oil and gas development is planned, and then follow up with two sets of tests to monitor for potential impacts from this specific activity.

Auto dealers vs. Tesla: Why the market will decide

By Brad Copithorne / Published: August 29, 2013

The European Union, the United Kingdom, Australia and the State of California have all set ambitious targets to reduce greenhouse gas emissions 80% by 2050. Given that a large share of global greenhouse gas emissions comes from transportation (including 29% of U.S. emissions), it will be very tough to meet this goal without “decarbonizing” our cars and trucks.

The most obvious solution is electric vehicles (EVs) charged by clean energy sources like solar or wind. While several startup EV companies – including Fisker, Coda and Better Place – have struggled, the Tesla car company seems to be succeeding. At least that’s the current view of the markets: Tesla shares have more than tripled since March and in May the company raised almost $1 billion in new capital.

How Smarter, More Flexible Energy Can Help Communities Weather Future Storms

By Andy Darrell / Published: August 27, 2013

Last week, the Hurricane Sandy Rebuilding Task Force released a Rebuilding Strategy, which aims to rebuild communities affected by Hurricane Sandy in ways that are “better able to withstand future storms and other risks posed by climate change.” From an energy perspective, the main goal of these recommendations is to make the electrical grid smarter and more flexible. This effort would minimize power outages and fuel shortages in the event of similar emergency situations in the future.

The Task Force is led by President Obama and chaired by Housing and Urban Development (HUD) Secretary Shaun Donovan. The recommendations put forth in the report were developed with Governor Cuomo, Governor Christie, and a number of federal agencies and officials from across New York and New Jersey, representing an unusual opportunity to make changes that will help communities weather future crises.

This key idea – smarter, flexible energy – is central to resilience, safety and quick recovery in a storm, as well as reducing the harmful pollution linked to climate change in the first place. This has been a key theme of EDF’s efforts to help the Northeast region respond to Sandy.

When the power grid went down on most of New York City following Hurricane Sandy, a number of buildings were able to keep their lights on thanks to existing microgrids and on-site, renewable energy sources. The Task Force report lays out a path forward for taking these isolated success stories to scale and making these clean technologies available to everyone.
