Renewable Energy Shines Brighter As Utility Bills Soar University Researchers Across Georgia Look at Alternative Energy Technology

ATLANTA -- Mar 31 - Florida Times Union

ATLANTA -- Erica Frank's idea of home improvement involves a little more than driving down to the local hardware store.

She installed a solar panel onto her Atlanta home to warm water and added triple-paned windows to trap in heat. Lights and appliances at her other house two hours north of the city run off power generated by a small stream.

Frank, whose mountain home is one of the few in the state to run independently of the electric company's power grid, said she made the changes several years ago because of concerns over power plant emissions rather than saving on her monthly bills.

"Financially, I don't think we're making a killing on it, but it makes me happy to know that I'm not giving Georgia Power one more nickel than I need to," said Frank, an associate professor at Emory University School of Medicine.

University researchers across the state, however, are looking into new technologies to make renewable energy less costly and more powerful.

Bernard Kippelen, associate director of Georgia Tech's Center for Organic Photonics and Electronics, is working on a new form of solar panels made from lightweight and cheaper materials, studying to see if the flexible cells can be used in retailers' inventory trackers or personal appliances, such as cell phones or radios.

Because the field is still new, he said, and it is unknown if the technology could be used on a mass level to run homes or fuel power plants.

While the focus to live "green" has yet to hit the mass market, increased attention on rising fuel costs and utility bills are giving advocates more steam in their arguments for alternative energy sources.

"I think there is an awakening to paying attention to energy issues," Kippelen said. "I think every time they fill their [car] tank it gets their attention."

Much of the electricity in the country is produced by plants burning fossil fuels, such as coal and natural gas. Georgia Power, a subsidiary of Southern Co. that provides electricity to 2 million customers in the state, also relies on nuclear and hydroelectric power.

But the surging expenses for those fossil fuels have hit Georgia Power hard, according to the company, which is asking state regulators to pass along the burden to customers.

"The rise is the rise in coal prices and the continued high prices in natural gas," said Georgia Power spokesman John Sell. "What's driving higher coal prices is the global coal market. Specifically, China's growth has almost doubled the price of domestic coal in some cases."

As a regulated utility, Georgia Power is allowed to recover its fuel costs from bill payers.

The company has asked the Public Service Commission for a $390 million increase in rates that would increase bills 9.8 percent, adding $2.70 to the monthly bills for the average residential customer.

Savannah Electric, another Southern Co. subsidiary, received approval last year for a 13.5 percent increase for fuel recovery that added $13 a month for the typical resident.

And Atlanta Gas Light, which supplies natural gas to companies that bill homes and businesses throughout the state, also is asking regulators for permission to raise more money for fuel expenses that would translate into a $1.39 monthly increase for home customers.

Public Service Commissioner Bobby Baker said Georgia Power officials promised to estimate better the fuel costs during the company's last fuel-recovery hearings in 2003.

"Now we're being told that the problem is getting worse rather than better, and we've been given a number of reasons why," he said.

The increases highlight the need for Southern Co. to start seriously looking at energy sources whose costs are less likely to fluctuate because of global demand, said Rita Kilpatrick, Georgia Policy Director for the Southern Alliance for Clean Energy.

She said renewable energy resources -- such as power generated by the wind, sun or plant material -- should be considered.

"The company needs to start diversifying its energy mix so that the kind of economic swings that you see in the world economy are not as harmful to Georgia Power or Southern Co.-affiliate customers," she said, adding that energy-efficiency programs also are not supported enough.

Renewable sources and energy conservation jumped into the public's attention after the oil crisis of the 1970s but have remained on the fringe of the country's total energy picture.

Oil supplies 35 percent of the country's energy needs, followed by natural gas and coal gas, according to the International Energy Agency, a think tank based in Paris.

Meanwhile, energy generated by water, biomaterials and wind make up less than 7 percent.

The expense of converting renewable energies into power has been one roadblock against their widespread usage.

Though consumer solar panels have dropped in price over the years and become more accessible and more than 13,000 wind turbines spin in California to produce 1.27 percent of the state's total electricity, traditional fuel sources are often cheaper to use.

"You're going to find as a rule of thumb that the cost of renewable resources are more expensive on a megawatt-hour than a megawatt-hour generated on coal or nuclear," Baker said.

He said that requiring the state's power companies to increase their use of renewable energy in the near future, as a bill introduced in the legislature tried to do this year, would make the problem of higher customer bills even worse.

But researchers are looking for ways to make using renewable energy on a large scale cheaper.

Georgia Tech's campus in Savannah is studying wind along the coast as a potential source for energy. University of Georgia researchers are looking at different ways to convert biomass, such as peanut shells and wood waste.

Southern Co. also recently delved into researching biomass, burning some prairie grass at its plant in Albany to reduce the amount of coal being burned as well as limiting polluting emissions.

A far-off option could be actually turning the grass or wood products into a gas, said Tom Johnson, research engineer for Southern Co.'s research and environmental affairs.

"As far as a potential renewable energy resource that could be a large supply one day down the road, the biomass would be the one because it's more plentiful [in the Southeast]," he said.
