Scientists: Smart Meters Are Safe

Image credit: Fort Frances Times Online

Smart Meters are crucial to fighting climate change because they are the first step in implementing the Smart Grid, which promises to make it easier for households to become more energy efficient and also integrate clean energy sources into their residential electricity system.

That is why it is a relief that, unlike cell phones, there is no cause for concern with the radiofrequency (RF) radiation of Smart Meters. That’s because the wireless devices produce an infrequent and incredibly weak RF field, according to scientists interviewed by Green D.C. Essentially they are computers that automatically send real-time information to the utility allowing homeowners to electronically manage their energy usage.

The meters not only exceed Federal Communications Commission (FCC) safety standards, but the mainstream scientific groups including the World Health Organization, the National Cancer Institute, Health Canada and the Maine Center for Disease Control and Prevention all say that low-intensity RF is safe.

Green D.C. interviewed two experts in the area of radiation about the risks associated with Smart Meters. They were: 

-- Richard Tell, who has 38 years of experience working on issues related to RF hazards, including stints at the Center for Devices and Radiological Health and the U.S. Environmental Protection Agency where he served as Chief of the Electromagnetics Branch and helped develop public exposure standards for RF fields;

-- and Dr. Jerold T. Bushberg, Clinical Professor of Radiology and Radiation Oncology at the University of California-Davis School of Medicine, and a member of the main scientific council of the National Council on Radiation Protection and Measurement (NCRP) as well as its Scientific Advisory Committee on Radiation Protection in Medicine.

Tell says that Smart Meters are so low powered that they operate in FCC license free bands, meaning they are deemed very unlikely to cause interference because they use an ultra high frequency of 900 mhz and one watt or less of power.

“They transmit very infrequently in terms of percentage of times of day. As an example, they may only transmit a few seconds in a day,” Tell explained. “If you look at the intensity of the field produced by transmitters, the RF fields are quite low in comparison to applicable safety standards for human exposure.”

Both Tell and Bushberg believe the current FCC standards are adequate. But Bushberg says the agency goes even a step further by requiring every meter to go through a stringent certification test to meet FCC rules.

“The evidence with low exposure to smart meters is very reassuring and the standards are adequate,” said Bushberg. However, he did caution that no legitimate scientist will ever say that any chemical agent is 100% safe, and that there are still things the scientific community would like to know and that further tests are warranted.

He said there is a latency period between exposure to a carcinogen such as radiation, and cancer. This period varies depending on the strength of the carcinogen and the type of cancer. That is why he advocates for epidemiology studies on populations that are occupationally exposed to high levels of radiation, such as plastics workers and cell tower climbers.

 “Of all the exposures of RF energy, Smart Meters would be very low and relatively easy to avoid,” said Bushberg.

Both Tell and Bushberg say that RF intensity inside the home is very low because as you back off only a few feet from the meter the intensity drops off dramatically. Also, meters transmit their signals out away from the homes they are mounted on, not towards the house. And finally, building materials and walls reduce the intensity of the already weak signal.

But what about people who claim they suffer from something called electrohypersensitivity, a condition that causes insomnia, split second head aches, high pitched ringing in the ears and nausea.

“I don’t understand how the RF fields produced by the Smart Meters (could) have caused any effects in these people. What I’m saying is that the strength produced by Smart Meters is so feeble in comparison to any health side effects of it. It’s not plausible,” said Tell.

And what about mesh networks and many meters in close proximity in an apartment complex. Wouldn’t that increase the intensity? No, says Tell, because the RF fields are linear so if you are close up to them you will only be exposed to the meter right in front of you. And if you back up a long distance from the meters, the RF is so weakened by the point it reaches you that it is harmless.

There are also some people who advocate for fiber optics instead of the wireless Smart Meter. According to Tell, this approach is not realistic because it is infinitely more expensive to have a wired connection to each home that wants one. And he says if people are really concerned about being exposed to radiation by a wireless Smart Meter, then the alternative of sending signals over a power line by a carrier current will have the unintended consequences of creating RF concerns near the power line and on the wires that go into your house.

The Obama Administration allocated $3.4 billion in the American Reinvestment and Recovery Act to jumpstart the installation of Smart Meters in every home as the first step in the National Smart Grid that will enhance energy efficiency and make  widespread adoption of renewable energy easier.

“This investment will place Smart Meters in homes to make our energy bills lower, make outages less likely and make it easier to use clean energy,” President Barack Obama said on February 17, 2009 after signing the bill into law.

Nearly two years later the consumer-level technology is rapidly being installed across the country by utility companies – there are ten million already installed in the United States and two million in California alone. Not to mention the 27 million Smart Meters already installed in Italy and nearly one million in Canada. And the United Kingdom has mandated that all homes have Smart Meters by 2020.

Other benefits of Smart Meters include remote meter reading, which takes carbon-emitting utility vehicles off the roads; the ability to pinpoint power outages, which improves response time; the ability to instantly shut off power if there is a house fire; the ability of families to monitor their energy usage online, potentially reducing consumption and saving money on electric bills; and more accurate readings than older meters.

“Smart Meters can’t help but enhance the reliability of the current system because utilities can know in real time what is going on in terms of loads. There are other people arguing that it’s big brother spying on me now. I would say that it’s really helpful for the utilities to better manage the grid itself to help better manage brownouts and blackouts,” said Tell.

Government Gets Cool

Can the Federal Government be cool? While the image of a nebbish bureaucrat slaving away in a soulless, fluorescent-lit warehouse will probably never go away, the Department of Energy has done a whole lot to change its image and help the environment by installing a "Cool Roof."

Energy Secretary Steven Chu recently oversaw the installation of light-colored materials on the roof of the DOE Headquarters West Building (the South Building's cool roof will be installed this spring). The 25,000 square foot roofing system will reflect heat and absorb less solar energy than a traditional roof, thereby decreasing energy use for cooling and removing carbon dioxide emissions from the atmosphere.

The two new roofing systems are expected to save taxpayers $8,000 in energy costs. Here is a video of Chu talking about the Cool Roof installation and why it's important.

DDOT's Gabe Klein Exits

Image Credit: Mark Gail/The Washington Post
NBC Washington is reporting that D.C. Transportation Director Gabe Klein has told his staff this morning that he will be departing when new Mayor Vincent Gray takes office this January.

I can't begin to describe how disappointing this news is and what a loss this is for Washington area "smart growth" transit advocates. Klein was nominated by Mayor Adrien Fenty to lead DDOT in 2009 and he ran with it. He has been instrumental in making our Nation's Capital a safer and healthier place to live by expanding non-driving options such as the two-way bicycle lanes on 15th Street and Pennsylvania Avenue, the popular Circulator bus system, and the Capital Bikeshare program. Capital Bikeshare is the largest in North America (until NYC implements its own bike sharing program) and was recently featured on CNN.

There is concern from Klein about a recent decision that could have negative results for the work DDOT has been doing to promote alternative forms of transportation. From the Washington Post:

"He also expressed concern about a little-noticed move in yesterday's budget gap-closing session to eliminate a special fund that allowed the transportation department the ability to easily transfer funds to and from projects. Klein said the move would change DDOT "from an enterprise agency to a more standard type of agency." He called the change "demoralizing."

"It's probably not a good fit for me going forward," he said. "It makes it a more administrative type of job."

Without the fund, he said, popular initiatives such as the 15th Street cycle lanes, Capital Bikeshare and the Circulator bus system "would require a longer conversation" with the council and others."

Ralliers to Obama: Keep Your Climate Pledge

Yesterday at noon a diverse coalition of climate hawks held a rally at Lafayette Park across from the White House to demand that President Obama keep his pledge to help the poorest nations deal with climate change.

The event, which was sponsored by 1Sky, ActionAid, Friends of the Earth and Jubilee USA Network, featured speakers including 1Sky Campaign Director Liz Butler, National Religious Coalition on Creation Care Chair Rabbi Warren Stone, and Dr. Mahmud Farooque of the Bangladeshi Environmental Network. There was also a live report by phone from Cancun with an update on the climate talks progress.

Below are pictures and video from the event. The videos are of Stone and Farooque speaking. After the speakers, there was a brief peaceful march on Pennsylvania Avenue in front of the White House. People chanted "Climate Action Now!" and held up signs that read "Obama: Be a Climate Leader."

Pictures: Metropolitan Branch Trail

The 8-mile Metropolitan Branch Trail (MBT) runs from Union Station in D.C. to Silver Spring, Maryland. As opposed to the popular Capital Crescent Trail, which runs from Georgetown to Bethesda, the MBT is lightly used, at least if the trip last Sunday on a brisk fall afternoon is any indication.

But the trail is one of the best kept secrets in our nation's capital. Much of it runs parallel to the CSX, Marc Commuter Line, Amtrak and Metro Red Line tracks northeast of Union Station. There are plans to connect the MBT to the seven Metro stations along the trail, and also to eventually connect the MBT to the Capital Crescent Trail, Anacostia Trails System and the East Coast Greenway.

There are long stretches of the MBT that run along lightly-used streets through historic neighborhoods like Brookland and Takoma Park. There are plenty of signs directing bikers such as the one pictured above, so you won't get lost while riding around the residential areas of Northeast Washington.

Here are pictures of the MBT.

The Capitol Dome can be seen in the distance and the New York Avenue Red Line Station can be seen just to the left of the Metropolitan Branch Trail.

The MBT is a smooth ride heading away from Union Station.
These trail lights are solar powered and use LED lighting.

Wonder where your trash goes? Well, if you live in the District it ends up at the Fort Totten Solid Waste Transfer Station. Basically the big landfill you see above.

The trail goes through historic residential neighborhoods such as this one.

D.C.'s First Electric Car Charging Station

Our Nation's Capital is doing its part to ensure that the charging infrastructure will be in place for the electric vehicles rolling out of dealer parking lots soon.

Drivers of the Nissan Leaf, Chevrolet Volt, Tesla Roadster and Model S, CODA and the Ford Focus Electric will already have one charging station in The District. Last Tuesday the city's first EV charging station was unveiled by outgoing Mayor Adrien Fenty, Department of Energy Undersecretary Cathy Zoi and District Department of Transportation Director Gabe Klein. It is located at the Franklin D. Reeves Center near 14th and U streets Northwest.

The station was built thanks to a $15 million Department of Energy grant that will make possible 4,600 charging stations around the country.

Bike Sharing in the Capital

I'm addicted to the Capital Bikeshare. So far I've used the bright red shiny bikes to have lunch in U Street and Georgetown, deposit a check at the credit union in McPherson Square, go to the gym in Golden Triangle and visit the dentist in Dupont Circle. According to my rental history log on the Capital Bikeshare website, my shortest trip was three minutes and my longest trip was 27 minutes, so I met the 30 minute time limit before the meter starts running. Therefore, my only bill so far has been the $50 annual introductory fee, which has since been raised to $75 for new members.

Here is a good video about how to use Capital Bikeshare:

Another Boneheaded Move by Bob McDonnell

Virginia's Republican Governor Bob McDonnell plans to raise the speed limits on 680 miles of rural roads across the state from 65 mph to 70 mph.

This anti-American decision will increase our dependence on foreign oil and make us less safe. Way to go Bobbie! During the 1970s oil crisis it was considered a patriotic duty to slow down and consume less fuel. And it was another Republican who called on Americans to sacrifice. From the website

"To conserve gasoline and oil, President Richard M. Nixon reduced the speed limit on national highways to fifty-five miles per hour and encouraged people to carpool and to lower their house thermostats."

Reducing the speed limit not only combats terrorism by reducing our dependence on the oil cartels, but also reduces harmful carbon emissions and saves drivers an average of 12% on gas.

But McDonnell would rather score cheap political points than take a stand and do the right thing by lowering the speed limits. Shame on McDonnell for this wrongheaded decision.

Rally To Restore Sanity: The Best Signs

Some of the smartest and most creative signs I've ever seen were displayed by the hundreds of thousands ralliers who gathered on the National Mall in Washington, D.C. on Saturday for Jon Stewart and Steven Colbert's much-hyped Rally to Restore Sanity and/or Keep Fear Alive.

It was inspiring to see so many people come out for a day of music, comedy and an impassioned plea by a serious Stewart at the end of the event for civility and, well, sanity in these economically uncertain and politically polarized times.

Hopefully all the young people at the rally will go out and vote on November 2nd to keep America moving forward.
