Honeybees are in trouble. They’ve been pestered by invasive mites. There are concerns about how agricultural chemicals might be affecting bees. And in recent years there’s been growing concern about the disappearance of honeybees. It’s called Colony Collapse Disorder. Lester Graham talked with Christy Hemenway with Gold Star Honeybees, based in Bath, Maine. Gold Star manufactures bee hives for beekeepers.

Lester Graham: Beekeepers expect to lose about fifteen percent of their bees over the winter, but for the past four years a survey by the USDA and the Apiary Inspectors of America has found that winter die-off has been about thirty percent. What’s going on here?

Christy Hemenway: Good question. One of the trickiest things about the Colony Collapse Disorder that most people have heard something about…is it’s difficult to study because it’s primary symptom is that the bees simply disappear from the hive. So there’s not a lot left behind to take to the lab and look at the details. So its primary symptom being that they disappear then the question would be why? and where are they going? That leaves us looking at conditions that bees are being raised in, and what are we doing to them, and with them, and it has left a lot of people scratching their heads, you might say. I think that a shift in the way we look at bees and possibly in the way we farm. If we were to begin farming in a way that supported bees it would begin to eliminate a lot of these things that are sort of dog-piling because it’s just a lot to ask a small insect to carry. And if we could do one less thing wrong, or one thing a little less wrong, then I think that we could really start to turn the tide.

Graham: When you say change farming, what do you mean by that?

Hemenway: Well the idea of industrial agriculture, or mono-cropping, where we’re growing, for instance, if you want to pick on a pretty large target, the California almond groves–it’s about 700-thousand acres of nothing but almonds. It creates an interesting situation. First off, you have to understand that almond trees bloom for just about 22 days out of the year. So if you’re a bee living in the middle of 700-thousand acres of almond trees, what do you plan to eat for the other three hundred and forty-some days of the year? So we’ve created the migratory pollination situation by having to bring bees in to these trees because there’s no way for them to be supported for the rest of the year. So if you’re farm is diverse and has things that bloom throughout the course of the bee season, when you’ve got warm enough weather, then you’re gonna find that your bees have got something to do, and something to eat, something to forage on all year round instead of for twenty two days which means you’ve gotta get ‘em out of there after that twenty-two days.

Graham: Short of keeping bees, is there anything else we can do that can help this situation?

Hemenway: Buy raw local honey from a local beekeper, maybe at a farmer’s market. That’s a great beginning. Another thing is: let your dandelions stand. Dandelions are fantastic–

Graham: Really?

Hemenway: Oh yeah, that’s great bee food, and it’s also some of the earliest food of the season. So don’t run out there with the lawnmower or the weed killer at the first sign of a dandelion, let that stuff go. Because it’s just natural, easy food, you don’t have to plant things for bees, the stuff that comes up all on it’s own is great stuff. So if you’re in any situation where you can let a lawn go a little more towards a meadow instead of a sculpted, barren, green bee-desert, do that. It’s really a wonderful thing to watch happen, first of all, and it’s just good for bees, to let them have that natural forage.

Graham: I’d love you to talk to my neighbors, that would be great.

Hemenway: Why, are they mowing down their dandelions?

Graham: Well they’re frowning at mine, let’s put it that way.

Hemenway: Oh, shame on them.

Graham: Christy Hemenway is with Gold Star Honeybees, thanks very much for talking with us.

Hemenway: You bet, thank you.

Coal: Dirty Past, Hazy Future (Part 3)

Coal has a reputation as a sooty, dirty fuel. More recently, environmentalists and the coal industry alike have become just as worried about the carbon dioxide released when coal is burned. In the third part of our series on the future of coal, Matt Sepic has this look at the science behind so-called “clean coal”:

As far as most leaders of the coal industry are concerned, the debate about global warming is over. It exists, carbon dioxide contributes to it, and it’s a crisis. But as they’re quick to point out, nearly half the nation’s electricity comes from coal. It’s domestic. It’s relatively cheap. And there’s a lot of it.

Steve Leer is the CEO of Arch Coal. Leer says unless Americans want that power to get really expensive, coal will have to remain part of the equation. But he says something has to be done about all that carbon dioxide.

If we don’t solve that CO2 question, the backlash of high cost electricity becomes an issue for all of us.

Arch Coal is the nation’s second largest coal producer. It’s paying for research into carbon capture and storage. The idea is to divert CO2 from smokestacks, compress it, and then pump it underground.

Engineering professor Rich Axelbaum is studying this with money from Steve Leer’s company. In his lab at Washington University in St. Louis, Axelbaum and two students are tweaking a device they call an oxy-coal combustor.

RA: “It’s a relatively small scale, quite a small scale for industrial, but it’s a relatively large scale for a university.”

MS: “It looks like a few beer kegs stacked end to end and welded together.”

RA: “Right, right.”

Axelbaum can burn coal inside this furnace along with a variety of combustion gases. He’s trying to figure out exactly how much oxygen to inject to yield pure carbon dioxide.

“We can capture the CO2 from a combustion process, by instead of the burning the coal in air, you’re burning it in oxygen, so the stream coming out of the exhaust is CO2.

Axelbaum says there’s no sense in filling valuable underground storage space with CO2 mixed with other gases if a power plant is built that can grab nearly pure carbon dioxide and store it.

He says energy companies already pump CO2 underground to extract crude oil, so some of the technology already exists. But environmentalists say the next step – which is crucial for any so-called clean coal power plant to work– is far from proven.

“No one knows in the industry whether in fact they can sequester carbon permanently.”

David Orr teaches Environmental Science at Oberlin College in Ohio. He says storing CO2 underground is easier said than done. And nobody knows if rock formations in different parts of the country can hold the huge amounts of carbon dioxide America’s power plants produce without it eventually leaking out.

Orr says because the goal is to reduce global warming, politicians would be better off funding research into other energy alternatives.

The metric here is how much carbon do we eliminate per dollar spent on research and deployment of technology?

Orr says the 3.4 billion dollars set aside for clean coal research in the federal stimulus bill would be better spent studying wind and solar power, modernizing the nation’s electrical grid, and finding ways to improve energy efficiency.

But the United States still has more than a century’s worth of coal reserves. And with plenty of money going into both research and advertising, talk of carbon capture and storage is certain to continue, even if it remains just that.

Wind Tax Credit Blowing Away?

The wind power industry has been growing.
But to keep growing, wind companies want more
taxpayer help. Chuck Quirmbach reports:

Some of the recent growth in wind generation is being fueled by a national
production tax credit. It’s due to expire at the end of this year.

The American Wind Energy Association is asking the public to encourage Congress to renew the
credit.

Association spokesman Jeff Anthony says, without the tax break, there’d be a slow down in new
wind projects and a potential loss of jobs.

“The longer it takes, the more in danger we’re putting the jobs in the wind industry at risk from a
drop-off in activity, both in project installations and in new manufacturing installations in this
country. So we need the PTC extended as soon as possible.”

Anthony acknowledges there’s a dispute in Congress over how to pay for the credit. Some
critics call the production tax credit ‘corporate welfare’.

Report: Forest Service Should Change Mission

A new report by a forest protection group says the increase
in logging in National Forests shows no signs of slowing. The uptick in logging is also happening in the Great Lakes region. The National Forest Protection Alliance says the U.S. Forest Service needs to re-evaluate its mission. The Great Lakes Radio Consortium’s Tracy Samilton has this
report:

A new report by a forest protection group says the increase in logging
in National Forests shows no signs of slowing. The uptick in logging
is also happening in the Upper Midwest/Great Lakes region. The
National Forest Protection Alliance says the U.S. Forest Service needs
to re-evaluate its mission. The Great Lakes Radio Consortium’s Tracy
Samilton has this report:


Logging companies are going after more acres in National Forests
because trees have regenerated after the large-scale clear-cutting of a
hundred years ago. But Jake Kreilick of the National Forest Protection
Alliance says the logging is a net loss for taxpayers, because the U.S.
Forest Service is heavily subsidizing it by building roads to get the
trees out. And Kreilick says it’s unnecessary – because lumber
companies have more domestic and global sources for wood than ever
before.


“The federal government does not need to be in the logging business any
more.”


But logging companies say with half the nation’s softwood in National
Forests, they do need the wood. They say the Forest Service is doing a
good job in managing the multiple users who rely on National Forests
for recreation, hunting and logging.

Solution for Arsenic in Drinking Water?

Researchers believe they have found a way to reduce arsenic levels in drinking water. They say, for people to drink water from wells or aquifers, the solution starts at the source. The Great Lakes Radio Consortium’s Jeff Bossert explains:


Chronic exposure to arsenic in drinking water has been linked to a variety of health concerns, including hypertension, cardiovascular disease, and cancer.


Researchers from the University of Illinois collected groundwater samples from 21 wells. They found that the wells with almost no arsenic in the water also contained high levels of sulphate-reducing bacteria, which convert the arsenic into a solid, where it drops out of the water. Dr. Craig Bethke led the study.


“What we’re saying is that if there’s sulfate in the water, then there’s probably sulfate-reducing bacteria active in the subsurface, and that means that a simple field test, which is very inexpensive and very rapid to protect sulfate, could identify safe water sources.”


Bethke says places where aresenic levels are high, sulphate salts, such as gypsum and calcium sulphate, can be injected underground to reduce arsenic levels.


Researchers say this information could prove to be invaluable in places where aresenic contamination is a major problem, including parts of the U.S., Australia, and Mongolia. The researchers’ findings were published in the journal Geology.

Report: Renewable Energy Can Kickstart Job Growth

  • Turbines like these not only could help produce energy from a renewable and seemingly infinite resource, but could also create thousands of new jobs, according to the Union of Concerned Scientists.

A new report says a national renewable energy policy could create thousands of new jobs in the Midwest. The Great Lakes Radio Consortium’s Erin Toner reports:

A new report says a national renewable energy policy could create thousands of new
jobs in the Midwest. The Great Lakes Radio Consortium’s Erin Toner reports:


The report by the Union of Concerned Scientists urges Congress to adopt a policy
requiring 20 percent of the nation’s energy to be produced using renewable sources
by the year 2020. Those sources could be wind, solar, or geothermal energy. The report
says such a policy could create thousands of new jobs in manufacturing, construction and
maintenance.


Jeff Deyette is an energy analyst with the Union of Concerned Scientists. He says
rural communities – especially farmers – could be the biggest winners under the proposal.


“Farmers that were chosen to have wind power facilities sited on their land could get up
to as much as $4,000 per turbine to lease on their property.”


Deyette says a national renewable energy standard could save consumers nearly 50 billion
dollars by 2020. He says that’s because increased competition from renewables would help
lower the demand and the price of natural gas.

Report Says Beach Closings at All Time High

A new report says the nation’s beaches were closed a record number of times last year because of high bacteria levels in the water. The Great Lakes Radio Consortium’s Rebecca Williams reports:

A new report says the nation’s beaches were closed a record number
of times last year because of high bacteria levels in the water. The
Great Lakes Radio Consortium’s Rebecca Williams reports:


The Natural Resources Defense Council releases a beach report every
year. It’s based on data from the previous summer. The NRDC says,
last season, there were more than 18,000 closings or advisories –
that’s more than any summer in the past 14 years.


Nancy Stoner is with the NRDC. She says health officials are doing a
better job of testing beaches and that has lead to more beach closings.
Stoner says it’s good that more beaches are being tested… but she
says most communities are failing to control pollution sources.


“We know where the problem comes from and that’s contaminated
storm water and sewage. One of the big problems this year is that the
Clean Water State Revolving Fund has been slashed in the White
House budget. And Congress has not restored that funding.”


Stoner calls the funding critical for cities to repair aging sewer and
storm water systems. The NRDC is calling on Congress to restore the
cuts to the fund in the fall.
