Survey Probes Americans’ Incorrect Opinions on Energy Efficiency

Quick – what’s the most effective for you to save energy? If you’re like many Americans, you’d say turn out the lights or turn up the AC’s thermostat. And, like many Americans, you’d miss the mark.

 

 Turns out, when figuring what we can do to go green, most of us overstate.
 
We think about curtailment—unplugging appliances, driving less, turning off lights—when improving the efficiency of our cars, appliances and home would take the biggest chunk out of our energy footprint.
 
That’s not a surprise to scientists who surveyed 505 Americans on their perceptions of energy consumption and savings. After all, curtailment is pretty easy: Flip a switch. Improving efficiency, on the other hand, requires research, effort, out-of-pocket expense: Does anybody want to buy a new washing machine when what’s downstairs works just fine?
 
The researchers started their survey with a simple open-ended question: What’s the single most-effective thing you can do to conserve energy? More than 40 percent of the respondents said one of three things: Turn off lights, drive less or change the thermostat.
 
Less than 10 percent identified what experts generally agree are the most effective measures – insulate the house or use more efficient appliances or cars.
 
"When you think about your life, what’s really easy to do is turn off the lights when you leave the room," said Shahzeen Attari, the study’s lead author and a researcher at Columbia University’s Earth Institute and Center for Research on Environmental Decisions.
 
Researchers note that for many of us, concerns about energy simply are not strong enough, compared to other daily worries, to warrant learning about energy conservation. But raise fuel prices or impose a tax on carbon that reflects its role in climate change and other environmental harm, and the public would have ample incentive to get educated in a hurry.
 
After all, it was the spike in gas prices in 2008 that brought the auto industry to its knees and triggered some of the nation’s sharpest declines in vehicle-miles traveled since recordkeeping began in the 1940s. "With a carbon tax we would see changes," Attari noted. "People are pretty elastic when it comes to the consumption of energy."
 

What you can do

 
Let’s face it: nobody’s going to go out and replace a working hot-water heater or washing machine. And few of us have a few grand lying around to replace our drafty old windows. But there are some easy steps you can take that can effectively cut energy consumption.
 
Buy your beverages in aluminum cans, not glass bottles: Making a glass bottle requires 1.4 times the energy of an aluminum can when virgin materials are used. Toss recycled materials into the equation and the difference jumps to 20 times as much. In part that’s because glass is so heavy.
 
Change your washer’s settings: Most people assume line-drying clothes—a time-consuming process to be sure—saves more energy than using colder water and optimizing loads. In fact the reverse is true.
 
Cool the room, not the house: Many of us think, incorrectly, that central air uses marginally more energy than a room air conditioner. The reality is it uses 3.5 times as much.

Massachusetts man decides efficiency is better investment than solar

SOUTH DENNIS — Michael Slattery’s home looks perfect for solar panels.

"I’ve got this huge roof," he said during a recent interview at his Cape-style home on Asack Drive. "South is right there."

An engineer by trade, he decided to bypass an expensive photovoltaic system and attacked the many small ways his family could reduce its energy use. Three years later they are saving more than $900 annually on electricity and natural gas bills.The home’s south-facing shingles get plenty of sun, but after Slattery took a renewable energy class his perspective changed on whether solar was the right move.

Slattery is among a growing number of homeowners and businesspeople who are taking advantage of incentives, courses and other opportunities in energy efficiency.

Cape Cod Community College has seen enrollment quadruple in its renewable energy and energy conservation classes in the past six years, said college spokesman Michael Gross.

Seventeen students participated in one such class offered by the college in 2004. This year 71 students took six different classes and in many cases are taking more than one class in the field.

Slattery learned to start with an energy audit to learn the best ways to save on energy bills at his house. After the audit, offered by the Cape Light Compact, the family first replaced traditional light bulbs with more energy efficient compact fluorescent light or CLF bulbs.

The audits, bulbs and other incentives are paid for through a charge on all ratepayer bills.

Slattery analyzed how much he would save by using a CFL bulb. By replacing three bulbs in an exterior candelabra-style light fixture with one CFL he is saving $26 a year. With the $42 cost of the new lamp and bulb his return on his investment was a little over a year and a half, he said.

He also discovered that heat was escaping his home through a poorly insulated crawl space. By sealing up the area, having an extra 10 inches of insulation blown into the attic and sealing small areas around electrical wiring in the home’s walls, Slattery cut off the flow of heat, and his money, going through the roof.

The cost: $2,000. But after rebates from the Compact and Mass Save, an organization sponsored by utilities and the state that provides incentives, training and other information on ways to reduce energy use, the total out—of—pocket expense was $500, he said.

By installing programmable thermostats and upgrading to Energy Star air conditioners, dehumidifiers and dishwasher, Slattery reduced his bills even further, he said.

Other measures cost even less. Slattery used plastic and insulation in a sun room to cover large skylights and other windows. He hid the plastic on the sky lights with colorful tapestries. He also bought smart power strips that automatically turn off plugs when a primary device is powered down.

Nothing has really changed for the family, said his daughter, Jaci, who wore a tie-dyed T-shirt a bit more colorful than her father’s tapestries.

"Honestly my dad just does all the work," she said.

And, while his wife — a math teacher — questioned Slattery’s actions at times, when she saw charts tracking their savings she was impressed, he said.

"It sunk in really quickly," he said.

Now he is sharing his experience with family members and friends. Several have already had energy audits done, he said.

His advice: Make a plan and take it one step at a time. "I think a lot of people are intimidated to get started," he said.

Through the host of rebates and the resulting reduction in demand, careful utility customers are becoming a small but growing part of the energy supply, Compact energy efficiency program manager Kevin Galligan said. By reducing demand for electricity the amount of total energy available can serve more customers.

It also means that investments in new transmission infrastructure can be deferred, Galligan said.

The Compact plans to issue a request for proposals soon for the second phase of a successful pilot program that will give homeowners even more control over their energy use by monitoring it via computer, he said.

A slew of other grants are available for energy retrofits and upgrades, including for agricultural projects, he said.

There is also a large queue of commercial and industrial projects seeking advice on energy improvements, he said.

"We may be an early indicator of economic recovery," Galligan said of the interest in energy efficiency projects.

 

Is Minnesota Power shooting itself in the foot?

August 11, 2010 on 3:10 pm | In General News | No Comments Carl Donovan

Historically, advances in household energy efficiency have come from colder climates.  No surprise, since homeowners in snowy, frigid places spend way more on heating than their more southerly counterparts.  I mean, what we call affectionately the "blower door", is more appropriately called the "Minneapolis Blower Door" (Retrotec fans, don’t come after me, we still say Kleenex, too!)

Consider this…  Minnesota Power has put together a website that does nothing more than educate their own customers about how to buy less of what they’re selling!

This ain’t no Greenwashing, folks.  This is where residential energy efficiency comes from.  (In the US, that is.  In North America, we owe much of what we know to Canada. Those Loons!)

What on Earth would possess a utility to encourage people to reduce their own bottom line?  How about good stewardship of the resources we’ve been "loaned"?  

Man, I tell ya, that’s just crazy talk.

Even if you’re not in Minnesota, you can still benefit from this site. Pay particular attention to the "Pyramid of Conservation".  Very cool. http://www.mnpower.com/powerofone/one_home/index.htm

Is Home Star DEAD? Quite possibly.

August 4, 2010 on 2:58 pm | In Cash for Caulkers | No Comments Carl Donovan

In what’s being described as a "punt" in the national press, the Spill Bill has been pulled from the floor of the Senate.  And, with it, Home Star.

From Politico.com:

Senate Democrats on Tuesday punted their oil spill response bill to next month, but the extra time doesn’t guarantee the measure will pass — far from it.

The delay virtually ensures that strategists from both parties will use the congressional recess to hone their plans, talking points and poison-pill amendments for any floor debate, all with an eye toward the midterm elections.

Harry Reid has let the Home Star Bill die miserablyMajority Leader Harry Reid’s decision to pull the plug on offshore drilling is the latest blow to Democratic efforts to move energy legislation, beginning with the deaths of a sweeping climate change bill and then a scaled-down renewable energy bill.

It initially appeared that the slender offshore drilling package was a must-pass bill with political momentum, but it became evident over the past week that the Nevada Democrat lacked the votes within his own caucus to force the issue as the Republicans held firm against it…
