Shawn Allee reports some
utilities are sending out info that might
get you to turn them down a bit:
Ever wonder if you’re an energy hog compared to your neighbors?
Well, some power companies are sending out graphs and charts to tell you.
Commonwealth Edison is a utility in Illinois.
It’s sending energy comparison letters to 50,000 customers this August.
Val Jensen runs the company’s program.
Jensen hopes competition will get people to conserve, because power bills alone don’t work.
“Despite pretty compelling economic reasons for customers to become more efficient at using energy, a lot of them don’t do it. Despite what they teach you in Economics 101, most customers don’t behave in the traditional, rational way.”
Jensen says, if enough people conserve energy, utilities can avoid building expensive new power plants.
Commonwealth Edison is just the latest utility to try energy comparison reports.
Power companies in New York and other eastern states will try them this year.
The McKinsey consulting group crunches all kinds of numbers for corporations.
It’s latest report suggests its cheaper to improve efficiency in heaters, homes, and electronics than it is to build new power plants.
It’s a welcome message to Lisa Jackson.
Jackson heads the US Environmental Protection Agency.
“I’m optimistic about Americans, who have so much common sense, saying, listen, the best energy is the energy we never have to use. It’s cheaper, it certainly means that we can invest in ourselves.”
The McKinsey report finds energy efficiency is economical in the long run, but it’ll take millions of consumers and businesses to boost power efficiency all at once to make a difference.
The authors recommend government and banks find new ways to finance home improvements.
They also recommend stronger efficiency labels on household electronics.

Whenever solar power is mentioned,
critics are quick to note – when there’s
no sun, there’s no power. Lester Graham
talked with the author of a report who
says one type of solar power can store
energy:
Lester Graham: Concentrating solar thermal, or CST, can store power. Basically, mirrors are used to concentrate solar rays, heat up water, generate power. The heated water can be stored as heat in tanks – like coffee in a thermos – and produce electricity when needed. Britt Staley is with the World Resources Institute. She’s the lead author of a new report on concentrating solar thermal. So, you found, if it’s done right, CST could be built instead of coal-burning power plants. How practical is that?
Britt Childs Staley: We think that concentrating solar thermal is a very exciting renewable energy technology precisely because of this potential for storage. If you incorporate thermal energy storage, or fossil fuel backup, with your concentrating solar thermal, you can actually use the power of the sun around the clock.
Graham: Now, the CST plants are expensive – they’re more expensive than building a coal-burning power plant. So, why build them if that’s the case?
Staley: With climate change as a major concern in the US and around the world, we are going to need to reduce our dependency on coal in the power sector. And currently, as you said, concentrating solar thermal power is more expensive than coal, but in this report we’ve identified several policy interventions that could help reduce costs. For example, a price on carbon such as the cap-and-trade mechanism in the current Waxman-Markey Bill, and then some solar-specific policy interventions would help as well.
Graham: Now, when you say ‘policy interventions’, really you’re talking about government subsidies, right?
Staley: Yes. Support for R-and-D, for deployment such as the investment tax credit that’s currently in place.
Graham: Obviously, the most sunny places would be the best location for a concentrating solar thermal plant.
Staley: Mm-hmm.
Graham: And the most sunny places are often in arid places, such as the US Southwest. So, they’re the driest places, and CST relies heavily on water. So, in the long term, what’s the solution?
Staley: There are several alternative cooling technologies that are available and that can cut water by up to 95% to 98% in places where that is a concern.
Graham: Is this completely experimental, or have we seen this done anywhere in the world successfully?
Staley: It’s absolutely been done successfully. Here in the US, we have some of the longest operating CST plants. And Spain is another good example of where CST deployment has been particularly successful to date.
Graham: How long would it take to build one of these, and how soon could they contribute, and how likely is it to happen, given the cost?
Staley: A lot of the plants that we see on the drawing board right now are expected to be in operation in the next 2 to 5 years. With climate change concerns, with climate change legislation working its way through the House and Senate, coal plant investments are not particularly attractive right now. And investors are very wary of putting their money into something that’s going to be significantly more expensive in the coming years. Concentrating solar thermal, on the other hand, is a zero-emissions power resource. Also, it has zero fuel costs.
Graham: Britt Staley is the lead author of a report on concentrating solar thermal power plants. She’s an associate researcher with the World Resources Institute’s Climate Policy Team. Thanks very much for talking with us.

As a climate change bill works its way
through Congress, businesses are bracing
for change to cleaner energy. Lester Graham
reports some homeowners are thinking about
generating their own clean electricity:
People like the idea of using rooftop solar or wind power to generate the electricity and selling extra back to the power companies. It’s called net metering.
But some state regulations don’t allow it.
James Rose is the Senior Policy Analyst for the Network for New Energy Choices. He says these days more states are smoothing the way for net metering.
“It started out looking like a very big patchwork quilt – where some states are doing well, other states aren’t doing well, other states aren’t doing anything – to more of a regional mosaic, now where we see, like, the northeastern states in the United States to really improve their net metering. States out West such as Colorado and California are leading the way.”
Some power companies block net metering where they can.
But Rose says as lawmakers watch neighboring states implement net metering, and then embrace the idea for their own states.

Eventually a climate change bill will work its way through Congress and President Obama has indicated he’ll sign it. But a civil rights group says a climate change bill will hurt the working poor. Lester Graham reports:
A climate change bill will mean more expensive energy until the nation can switch from fossil fuels like coal and oil to renewable energy such as biofuels, wind and solar.
Roy Innis is the Chairman of the civil rights group Congress of Racial Equality. He says higher energy costs will hit the working poor hardest.
Democrats say they’ll get tax rebates to offset the higher costs. Innis doesn’t like the idea.
“We don’t want energy welfare. This is our new civil rights battle: how to have abundant and available, reliable energy at a reasonable cost.”
And Innis says we have that now with fossil fuels.
The Obama Administration says climate change legislation will eventually lead to cheaper energy for everyone and reduce the cause of global warming —which, in the end, could cost people a lot more.

Researchers and start-up companies are looking for new ways to power the country. There’s been a lot of hope for hydrogen. But as Mark Brush reports there have been some bumps for companies on the road to the new hydrogen economy:
There has been a lot of excitement about hydrogen fuel cells for awhile now.
Ten years ago we talked to a rep at a company called Plug Power. He was excited about selling a dishwasher-sized fuel cells that could power and heat your home.
“The only barrier to fuel cells is that people don’t know about them.”
Turns out, that wasn’t the only barrier.
It’s expensive to make these things, and the units weren’t as efficient at heating as they hoped they would be.
But the company is still around, and they are still hopeful about fuel cells for your home.
Andy Marsh is the president of Plug Power.
“So the industry hasn’t moved ahead as rapidly as we would like. It sometimes takes many more years to makes some progress than you had originally hoped.”
Marsh says his company is selling fuel cells in places like India, but he says fuel cells for our homes in the US are probably still three to five years away.

Solar panels and wind turbines get most of the buzz, but it’s far easier and cheaper to save
energy than it is to make more of it. Now, President Obama’s economic stimulus package
is pouring billions into energy-efficiency programs. As Amy Standen reports, it’s shining
a new spotlight on some of the simpler ways we can all reduce our energy use:
Sure, I’ve thought about buying solar panels to put on my roof. There’s a perfect spot on
the south-facing slope – maybe we could power the whole house. But there are some
easier things we could do first – like insulate the attic or weather strip the doors. And yet,
somehow I never quite get around to them.
Why is that? Well James Sweeney directs the Precourt Energy Efficiency Center at
Stanford, and he has a theory.
“Energy efficiency turns out to have low salience to people.”
Which is to say, it’s maybe… a little bit boring?
“It’s very boring.”
But if your eyes start to glaze over at the mere mention of the word “efficiency,” consider
the compact fluorescent light bulb.
“The easiest thing everyone can do is change their lighting.”
If everyone in the U.S. traded in their old incandescent light bulbs for compact
fluorescents, we’d cut electricity use by about 2%.
Which, maybe, doesn’t sound so impressive – until you consider the fact that all the solar
and all the wind power combined in the entire country amounts to point .4% of our total
energy use. That’s 0.4.
“The cleanest energy is the energy you don’t need in the first place.”
That fact has not been lost on the Obama White House. The American Recovery and
Reinvestment Act is pouring approximately 20 billion dollars into efficiency projects.
Five billion of that will fund what’s called the Weatherization Assistance Program, which
helps low-income families weatherproof their homes. To qualify, a family of four must
make less than $44 thousand dollars a year.
(sound of someone giving directions – “Take 25 and go to El Paso Road”)
That stimulus cash funds local non-profits like Community Resource Project, in
Sacramento, California. Since January, Community Resource’s budget has tripled, from
1.3 to 4.5 million dollars a year. They’re buying new trucks, hiring at all levels, and
going to more and more homes.
(sound of knocking at a door)
Like this one – a five-bedroom stucco ranch house in a newer suburban development
outside of Sacramento.
(sound of door opening)
“Hello, how are you doing?”
At the door is TinaMarie Dunn, a family friend who’s showing us around today. She
gives a squeeze to two-year old Anaya, one of ten children who live here.
“Look Anaya, say cheese!” (Anaya: Cheese!)
Dunn says utility bills here can hit $500 dollars a month. She says the house just doesn’t
work right.
“When the heat is on, downstairs is hot, downstairs is cold. When the air’s on, the
upstairs is cold, the downstairs is hot.”
Community Resource’s Dana Gonzalez walks into the kitchen, and pauses to take a look
around.
Standen: “So when you walked in, what was the first thing you saw?”
Gonzalez: “It’s funny. You see this door shoe and you see, actually the bottom rubber
is gone.”
He points to a two-inch gap under the front door.
“And if you put your hand here, you can actually feel the air. Anytime they kick on
their heat and cool, that’s definitely affecting their house, and in the long run, affects
their bill.”
Community Resource will spend about $1500 here, aiming to cut monthly utility bills by
as much as 20%.
They’ll weather strip the doors, patch up holes in the walls, install CFL bulbs. We’re not
talking solar panels or radiant heating – just small, mostly inexpensive adjustments that
cumulatively, have a huge impact.
The White House says these efficiency projects will create thousands of jobs, but there’s
also concern that the huge cash infusion is a recipe for fraud and mismanagement.
Department of Energy officials have called for extra vigilance in the disbursement of
weatherization cash. But, they say, the benefits, both environmental and economic, far
outweigh the risks.

The government is spending billions of taxpayer dollars on a new “smart grid.” Mark Brush reports the new grid could eventually save you money on your energy bills:
Right now – power just goes from point A to point B.
But with a smart
grid system, your house can talk back to you and the power station.
The
meter could tell you how much it costs to heat your water, for instance.
And the power company will be able to talk to you if they’re having a
problem.
So, if they’re headed for a blackout, they can text message you
or e-mail you and ask you to shut off your A/C.
Jesse Berst is the founding editor of Smart Grid News dot com. It’s a trade publication.
He says, if electric grids are updated across the country, it would cut
down on pollution and save money.
“And that means there’s billions, tens of billions of dollars of power
plants and lines that we wouldn’t have to build over the next couple of
decades.”
Upgrading the system won’t be easy.
Each state has regulatory agencies that oversee thousands of electric
suppliers.

There’s 11-billion dollars in the new economic stimulus plan for upgrades to the electric grid and so-called smart meters. These smart meters hook up to your home and give the utility company real-time feedback on how much energy you’re using. Rebecca Williams reports Google is working on a way to let you see that information:
Google’s system is called PowerMeter. It’s in beta testing right now but the idea is: if you get a smart meter, you’ll be able to see exactly how much energy your TV, fridge and computer use.
The system will hook into the info utility companies draw from your home. Then, you can log into your secure i-Google website, for free. And get real-time feedback so you can figure out how to spend less on your power bill.
Kirsten Cahill is a program manager at Google. She says they’ve been testing the PowerMeter around the office:
“I think people are surprised about things like their oven; how much the oven uses or the microwave. Things that you using every day that are actually, you know, pretty huge energy users.”
It’ll probably be a year or more before the Google system is open to everybody.

Economists looked at utility bills of homes in California on the hottest days
of the year.
Geoffrey Donovan is with the Forest Service Research Station.
He says, if you have shade trees on the south or west sides of your home,
those trees reduce your electricity use by five percent.
“So putting a tree somewhere it’s going to cast shadows at the warmest time
of the day. The other thing you want to think about is winter sunshine.
Particularly on the south side of a house you may want to put a deciduous
tree as opposed to an evergreen tree so in wintertime you’ll get some
sunshine through that.”
Donovan says how close you put those trees to your house matters too. For
the most energy savings, shade trees should be within 40 to 60 feet of your
home.
