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.

Cleaning Up Coal-Fired Power Plants

Acid rain, mercury pollution, and huge amounts of the heat-trapping gas carbon-dioxide are the down sides of burning coal in electric power plants. And yet, some energy experts are saying America should be using more coal. They say new coal technology can produce electricity with few of the pollution problems of traditional coal power plants.

Acid rain, mercury pollution, and huge amounts of the greenhouse gas carbon dioxide are the down sides of burning coal in electric power plants. And yet, some energy experts are saying America should be using more coal. They say new coal technology can produce electricity with few of the pollution problems of traditional coal power plants. Bob Kelleher reports:


Coal has a well deserved bad reputation. Typical coal burning power plants release mercury, sulfur, nitrogen oxides, and lots of carbon dioxide. Those releases mean toxins in the air, soot, acid rain, and many believe global warming. But Tom Micheletti says there’s a way to use coal with very little pollution.


Using heat, steam, pressure, and oxygen, coal can be broken down to a relatively clean gas, and a handful of other chemical products. The gas is burned, to turn generators and produce electricity. The technology is called Integrated Gasification Combined Cycle. Micheletti says, the technology isn’t new, but applying it this way is.


“All we’re doing is marrying the gasification technology, with a technology that’s been well established, the combined cycle gas technology – power plant technology. And all we’re doing is simply putting those two technologies together.”


Micheletti is Co-President of Excelsior Energy, a company formed to build the nation’s first large scale coal gasification electric power plant in northeast Minnesota. At 600 megawatts, it would dwarf demonstration plants now online in Indiana and Florida.


Some experts say coal gasification is not only promising, it’s more practical than nuclear power, natural gas, solar or wind. Daniel Schrag is a climatologist and head of the Harvard University Center for the Environment.


“We have a lot of coal in the US. We’re very fortunate that way. The problem is that coal produces more carbon dioxide per unit energy than any other fossil fuel. And so, when we burn coal and make electricity, it’s really bad for the climate system.”


Schrag says there’s more carbon dioxide around us now than humans have ever experienced. Carbon dioxide is a greenhouse gas. Most scientists believe it blankets the earth, forcing temperatures higher.


Schrag says, when used to generate electricity, coal gasification has big advantages over conventional power plants, because it can capture CO2.


“You get more energy for the amount of coal you put in, and that’s good for carbon emissions. The other thing is that it seems to be cheaper in an IGCC plant, or a gasification plant, to capture the carbon dioxide after one extracts the energy from the coal, and then makes it much easier to capture it and inject it into a geological reservoir.”


The key, Schrag says, is a process called sequestration. You capture, and then sequester it, or lock that carbon dioxide away, where it won’t escape into the atmosphere. It’s already being done.


This is the Dakota Gasification Company, just outside Beulah, North Dakota. Here they turn coal into a burnable gas and almost a dozen other products. They also produce plenty of carbon dioxide, but the CO2 is not vented into the air; it’s trapped and compressed. That’s the noise.


The CO2 is piped more than 200 miles into Canada where it’s pumped into oil wells, forcing the last oil out and leaving the CO2 underground. Near oceans it can be pumped under deep ocean sediments, where it stays put.


And that’s all very good, but others say even good power plants might be a bad idea.


Ross Hammond is with the Minnesota based organization Fresh Energy. Hammond says gasification’s proponents are overlooking conservation and the opportunities for clean energy.


“When we’ve exhausted all the clean options including biomass and photovoltaics, and wind and the other options, then we need to look at coal.”


But Harvard’s Daniel Schrag says it’s not as simple as pushing money toward pollution free energy.


“And the answer is complicated. The answer is perhaps not. It may be that coal is so cheap that even the extra cost of capturing the carbon and storing it underground may still make it cheaper than the alternatives, than wind and solar.”


Schrag says we’ll need it all – nuclear, hydro, wind and biomass. But to satisfy the nation’s hunger for energy, he says we’ll need coal – best used in coal gasification.
