One out of every five light bulbs sold in the U.S. is a compact fluorescent. That’s
according to new market data put out by the Environmental Protection Agency. Mark
Brush reports:


It appears the days are numbered for Thomas Edison’s most famous invention. That’s because fewer people are buying incandescent light bulbs. The EPA says that compact fluorescent light bulbs made up 20% of the overall light bulb
market last year. That’s more than double than the previous year.


Maria Vargas is with the EPA’s Energy Star Program. She says the compact fluorescent
bulbs – or CFLs – are more expensive to buy, but when you do the math, they’ll save
you money in the long run:


“A CFL lamp will save you about $30 or more in electricity costs over each bulb’s
lifetime. They use about 75% less energy and they last up to about ten times longer.”


The U.S. government will officially begin phasing out the higher wattage incandescent
bulbs in 2012.

Plunging Into Low-Flow Toilets

Low-flow toilets left some people flushed with anger when the products
debuted in the 1990’s. But the Environmental Protection Agency is
pushing ahead with a voluntary program to create toilets that use even
less water. Chuck Quirmbach reports some toilet manufacturers say they
want to join the new water-saving market and hope consumers are ready
to buy:


Rob Zimmerman admits there are plenty of jokes about toilets, but the
water engineer for the Kohler Corporation takes the bathroom commode
very seriously.


“I’ve heard people say that the toilet is kind of the foundation of
modern civilization… that modern sanitation allowed for the growth of
cities and allowed for the decline of infectious diseases.”


And now Zimmerman has a handle on a new role for toilets: saving water.
Studies have shown that toilets can account for up to 30% of
a household’s water use. Water prices are going up and in some fast-
growing communities water supplies are growing more scarce.


So, the EPA created a voluntary program it calls Water Sense. It aims
to get toilets to use 20% less water than the newer toilets you’ve
probably seen that were mandated back in the 1990’s. This new
generation of toilets goes from 1.6 gallons per flush to about 1.3
gallons, and still meets performance guidelines for producing a clean
bowl.

Kohler and other toilet makers are trying various ways to get to 1.3
gallons. After looking at a 1.6 gallon model, Rob Zimmerman lifts the
tank lid on a 1.3:


“What you see that’s different here… is remember the other one had
that red flapper? This canister here, that lifts straight up when you flush
it, so all the water can move from all different directions and go down
down the valve. It’s a bigger rush and so the actual time that this
flushes is a little bit shorter than the other one.”


Zimmerman says other higher efficiency models use what’s called a dual-
flush system that sends away one amount of water for liquid waste and
another for solids, with an average of 1.3 gallons.


Another type is the so-called pressure assist, a louder system that
compresses air to force the smaller volume of water out quickly.
Under its new Water Sense Certification program, the EPA has put out
final specifications for the 1.3 models.


Kohler is getting ready to submit six toilet models for certification,
which the EPA compares to its Energy Star program for things like
computers. EPA Water Administrator Benjamin Grumbles says the public
can be confident about a third party certification system the EPA has
created:


“The agency working with the scientific community and with independent
testing organizations want to make sure that consumers, when they see that
Water Sense label, they will be able to have confidence that the
product will perform well, and it will lead to increased savings. Not
just in terms of water, but also reduce the water bill and reduce the
energy bill as well.”


But it may take a while to build that confidence. At a home remodeling
show, bathroom fixtures store owner Rich Libbey said he’s seen low-flow
toilets elsewhere that have not worked properly.


“Some of the Carribean Islands that are desert islands flush on a
European quart of water, but they don’t clean the bowl. So, later on in
the evenings, for example at a bar or resort, the toilet gets kind of
gamey.”


But Libbey says he’s willing to give companies like Kohler the benefit
of the doubt of reliably getting to 1.3 gallons per flush. Like most
high-efficiency energy-saving systems, the up-front costs are a little
higher.


The Kohler Corporation says its new high-efficiency toilets might cost
an extra fifty dollars to buy, but estimates the financial payback of
using less water could come in just a couple years.

The Direction of U.S. Energy Policy

Americans are thinking about energy more. We’re facing higher energy prices, there’s worry about climate change, and there are questions about whether our need for foreign oil is forcing the country into wars in the Middle East. Even former oilman President Bush says we have to kick our addiction to oil, but what’s the government doing about it? Stephanie Hemphill looks at our national energy policy and its priorities:


This winter, a handful of people around the country won’t have to worry about oil or gas prices. Jamie Juenemann is one of them. He lives out in the country in northern Minnesota, and he’s installed his own energy plant.


Behind the house, there’s a pole reaching above the trees. At the top, a modern windmill turns as it catches the wind. There’s also a solar hot water heater, and a geothermal heat pump, that brings underground heat into the house.


“This was the final phase in our goal to become carbon neutral; essentially producing as much energy as we’re consuming.”


Carbon neutral means not using fossil fuels that emit carbon dioxide, believed to be a greenhouse gas, and warming the planet.


Of course these systems aren’t cheap. Juenemann took out a second mortgage to pay for them. It was a big decision, but he says he’s doing what he can to make sure his young daughters will inherit a livable world.


“It’s all about choices. We have the choice to either purchase a Chevy Suburban, or we can use that same outlay, that same expense and put in some renewable energy systems.”


Eventually these systems will pay for themselves, and the Juenemann family will have free hot water, electricity, and heat.


The government helps pay for some of these systems; as much as three-quarters of the cost can be covered by tax-breaks and rebates. The trouble is one of the major federal subsidies ends next year, and others are limited to the first few buyers in a fiscal year. Businesses that sell renewable energy systems say that on-again, off-again subsidy approach by the government makes it difficult to stay in business to provide the alternative systems.


Politicians have been sending mixed messages about energy. Last year’s energy bill offered subsidies for nearly every energy source, without sending a clear message favoring one over another. Congress even offered subsidies for fossil fuels.


And that makes sense to John Felmy. He’s chief economist at the American Petroleum Institute. He says the country depends on traditional sources — including the 40% of our total energy budget that comes from oil. He says the government should subsidize exploration and research on fossil fuels.


“You have to say where can you get the biggest impact from encouraging additional supplies, and those numbers of 40% clearly dwarf what you have from the alternatives.”


He says to keep the economy strong, the government should make it easier to drill for oil and gas, and to bring energy to where it’s needed.


Another government approach to the challenge of energy is to reduce the demand. Some groups predict conservation could cut energy needs as much as thirty percent.


J. Drake Hamilton is a scientist with Fresh Energy, a non-profit organization. She says conservation is cheaper and cleaner than producing more energy.


“Every time you cut energy use, you cut pollution. Every time you increase it, you increase pollution.”


And some people regard pollution as a hidden cost of traditional fuels. They say if consumers directly paid for the environmental and health costs of burning coal and oil and gas, the prices would be a lot higher. Economists call these “external costs,” and they argue over how to set a price on them.


Environmentalists say we should start charging an extra tax on fossil fuels because they contribute to global warming. At the same time, we could reduce the income tax, so the shift would be revenue-neutral, but the idea is still likely to be politically unpopular. A higher tax on fossil fuels would mean higher prices, which would make renewable energy systems more competitive.


There’s nothing new about taxing things that are bad for us, and subsidizing things that are good. But so far, when it comes to energy, Congress hasn’t been able to agree on what to discourage, and what to encourage.

Cooling Concerns About Air Conditioning

  • For some, a ceiling fan just isn't enough to cool down. (Photo by Tarrer Pace)

As the hot weather settles in, air conditioners are
being wedged into windows everywhere. The Great Lakes Radio
Consortium’s Karen Kelly usually tries not to use one. But
she finds as the temperatures rise, her concerns for the
environment evaporate.


Every year – late spring – I start my annual denial of the fact that I need air conditioning.
The problem is, I really relate to the people who wave it away and say, all you need is a ceiling fan and nice cold glass of water.


Like my friend Ross, who has no air conditioning on the job as a home renovator, and no air conditioner at home, either.


“Well, it’s not really anything ethical. I just find that recycled air, it sort of smells bad. And I would prefer breathing steamy but clean air to cooled but stale air.”


Ross is one of those people who thinks it’s silly to use air conditioning where we live, which is in Ottawa, Canada. I mean, come on, we might only have a couple of weeks of hot weather. And in the beginning, I try to do without.


I have fans. I drink iced lattes. I take cool baths.


But the truth is, I can’t take it. My brain just stops functioning properly. Like the time my husband came home to find me trying to work at the computer in tears, because I was so hot. Meanwhile, the air conditioner is in the window, but I was refusing to turn it on.


Part of it is that I’m worried about the impact on the environment. I talked to Corey Diamond at the Clean Air Foundation in Toronto and asked him how bad is air conditioning really?
He agreed it uses a lot of electricity, but even worse, he says we’re all using it at the same time.


“Everybody sort of comes home at five o’clock, turns on their air conditioning, and we get to a point where the electricity grid is at the peak demand that it can access. What ends up happening is when people are demanding more power, they have to use as much coal as they can to meet that demand.”


And that means more pollution, which leads to smog, health problems and maybe even climate change.
Despite that, I recently decided I had to have air conditioning in my car – both for my own comfort and the safety of other drivers.


I tend to get disoriented in the heat. I usually relied on a bottle of ice water between my knees and the windows wide open. About an hour later, I’d be taking the wrong exit off the highway.


So, I recently took my 1990 Honda Accord into the shop to find out if they could fix it. I was prepared to spend a few hundred dollars, maybe more. Then they call back with a quote of one thousand eight hundred dollars.


That’s probably more than my car is worth. The guy on the phone says at that price, he won’t let me get it fixed, even if I want to. So the car is out of the question. But at home, the heat creeps into my living room, and the temptation becomes too great.


Third day of plus 85 temperatures… What more do I have to say?


(Sound of air conditioning)


My 18 month old daughter stands in front of the air conditioner. She reaches her arms towards it. She basks in its coolness.


“How does that feel? Good… good…good!”


I’ve given in to my weaker self. But I’m still determined to use the air conditioner sparingly.
Corey Diamond at the Clean Air Foundation gave me a bunch of ideas on how to do that.


“Keep the blinds drawn during the day. You want to install some ceiling fans if you have some. And lastly, you can add a timer to your air conditioner. You sort of set it to come on at four o’clock and if you get home at five o’clock from work, your house is cool, but it hasn’t been cooled all day.”


At first, Diamond’s group tried to get people to stop using air conditioning. That didn’t work. So they switched gears. They started a program in Toronto where you can trade in your old, inefficient air conditioner for a rebate on a new one. Diamond says the newer ones use as much as 70 percent less electricity.


So as I sit here, telling you this story, I have a new air conditioner with an Energy Star sticker on it.
Which means either the Canadian or American government deemed it more efficient. I do kind of feel like I’m working in a wind tunnel. And I miss the sounds of the birds and squirrels outside my window. But yet, I feel comfortable.


Now I’m reluctant to turn the air conditioner off.
