Offshore wind could be the next big wave for US

To supporters, Cape Wind represents an opportunity to be a leader in clean energy but opponents say it would hurt tourism


The Cape Cod resort area, famous for sandy beaches and centuries-old fishing villages, could in the next few years claim a new title of home to the US’ first offshore wind farm.

The US has experienced a surge in investment in wind power over the past four years, more than tripling its ability to turn wind into electricity. But construction has been entirely on land and largely in the US’ rural midsection — leaving open the costly challenge of how to transmit power to the densely populated coasts where it is most needed.

That could be changing. Developers have proposed wind farms off Massachusetts, Rhode Island, Delaware and New Jersey to meet the electricity needs of the East Coast.

“They’re building these wind farms in the Midwest fast, which is great. The problem is there’s no people,” said Rhode Island Governor Donald Carcieri. “Where is the energy needed? The energy is needed here on the East Coast.”

The Cape Wind project in 2001 became the country’s first major proposed offshore wind farm. Its developers aim to construct 130 towers, which will tower 130m above the surface of the Nantucket Sound.

To supporters, Cape Wind represents Massachusetts’ chance to be a leader in clean energy. It would generate 420 megawatts of power, enough for 336,000 typical US homes.

Opponents, including Democratic Senator Edward Kennedy, who has a home on the Cape, say the towers, 8km from shore, would be a risk to navigation and hurt tourism.

Cape Wind’s developers need one last major regulatory approval, from the US Department of the Interior. Should they get it, they expect to have the project up and running in two years, which will require finding more than US$1 billion.

Jim Gordon, Cape Wind chief executive, said he believes investors will come through.

“There’s no doubt that since last summer we have kind of fallen into a significant capital financing crunch,” he said. “I’m confident that the Cape Wind project is going to be financed.”

The administration of US President Barack Obama sees investment in alternative energy sources like wind and solar, which do not emit carbon dioxide that aggravates global warming, as a cornerstone of its economic and energy policies.

Momentum is on wind’s side. Last year developers invested more than US$17 billion in new US wind farms, according to the American Wind Energy Association. Wind now represents more than 1 percent of the US electricity supply.

Companies including US conglomerate General Electric Co, Germany’s Siemens AG and Denmark’s Vestas have seen demand for turbines soar.

But onshore wind must deal with the cost and complexity of building transmission lines from Texas, Minnesota and other leading wind producing states to demand centers.

Texas oil billionaire T. Boone Pickens blamed the difficulty of building transmission lines and bleak credit markets for his decision this month to postpone plans for what would have been the largest US wind farm.

“It really wasn’t surprising that it was discovered to be a Herculean task to permit and capitalize this type of transmission infrastructure,” said Paul Rich, chief development officer of Deepwater Wind, which is working on US$1.5 billion of projects off Rhode Island.

Deepwater, backed by hedge fund DE Shaw and wind developer First Wind, plans its turbines 25km offshore, which would make them practically invisible from the coast.
