Sen. Harkin: Biofuels Don’t Contribute to World Hunger

Sen. Tom Harkin (D-IA) dismissed concerns Thursday that ethanol and other biofuels are contributing to rising food prices and world hunger.

Appearing before the Senate Committee on Energy and Natural Resources, Harkin said a recent study’s claims that up to 192,000 deaths last year could be blamed on expanded biofuel production was just the latest in a long line of misguided attacks on ethanol. The five-term Senator said the U.S. has not reduced the amount of corn it exports, and increased ethanol production in recent years has been matched by increased corn production.

“This is one of those [claims] that just keeps coming up all the time, and in which there’s just no basis in fact,” he said. “It hasn’t been that we’re taking anything out of the food chain. We simply have increased the productive capacity of corn.”

But while Harkin does not see the study’s findings as cause for concern, he said biofuel production will face challenges in the years ahead.

Biofuels currently account for nearly 10 percent of U.S. gasoline supplies. The 13 billion gallons America produces each year fall well short of the 36 billion gallons 2007’s Renewable Fuel Standard requires the country to produce by 2022.

Harkin said that number is still attainable, but several of the committee’s members cited concerns that the U.S. has maxed out how much ethanol it can produce. This fear stems from the fact most fuel in America is 90 percent gasoline and 10 percent ethanol, creating a “blend wall” that prevents ethanol from accounting for more than 10 percent of the nation’s fuel.

“We’ve reached a crossroads for our biofuel policies well before most of us expected to reach one,” Sen. Lisa Murkowski (R-AK), the committee’s top Republican, said. “And nothing characterizes that crossroads better than the so-called blend wall.”

Harkin said the Biofuels Market Expansion Act, which he introduced in January, would help the country push past the blend wall. The bill would require car companies to make more flex-fuel vehicles – which can operate on more than one fuel at a time – and gas companies to equip more of their filling stations with blender pumps that provide fuel with higher concentrations of ethanol.

Another factor that could lead to increased use of biofuels is the gradual relaxing of government restrictions, which Harkin said could drive the market for fuels with higher ethanol concentrations. The Environmental Protection Agency granted waivers in January that allow cars built after 2000 to use fuel with a 15 percent concentration of ethanol, known as E15.

The committee’s chairman, Sen. Jeff Bingaman (D-NM), said he wasn’t convinced incentivizing more ethanol production was the best way to reach the Renewable Fuel Standard. He favors an approach that would allow “drop-in” biofuels, advanced biofuels that are still several years away from viability, to compete fairly with ethanol in the open market.

“If ethanol can fuel more than 10 percent of our transportation needs in the near term, then we should explore a path toward enabling it to do so,” Bingaman said. “However, we should not go so far in locking our infrastructure into ethanol as the renewable fuel of choice that we prevent different, and perhaps even better, renewable fuels from coming to market in the future.”

Both Bingaman and Harkin lauded the rapid expansion of biofuels in the last decade, and said it would continue to play a large role in weaning America off of foreign oil.

“Biofuels is – and will continue to be – our most important strategy for reducing dependence on imported oil,” Harkin said.
