Energy Wanted: Offshore Wind Farms Need Apply

In our country’s race to become more energy independent, offshore wind farms have taken a back seat to the offshore drilling debate that is currently heating up in our politics. Realistically, we could be seeing these offshore wind farms begin to pop-up off the Atlantic coast sometime in the near future, way before any oil rigs. CNN.com tells us:

Delaware hopes to be the first state to construct a wind farm off its coast. The project, scheduled to be completed in 2012, is one of several offshore wind proposals that have cleared significant hurdles in recent months.

Proponents say wind offers more long-term energy independence than offshore oil. Residents along the Eastern seaboard are embracing it as a stable-priced, environmentally friendly energy alternative.

“When people see the price of gas hit $4, they are very open to having discussions about alternatives,” said Stephen Smith, executive director of the Southern Alliance for Clean Energy, a nonprofit group.

Wind energy today accounts for only 1 percent of the nation’s electricity. A May report from the Energy Department concluded wind energy could generate 20 percent by 2030, with offshore sources accounting for nearly 20 percent of that. Projects mostly would be located along the Atlantic coast because the seabed floor elsewhere drops off too quickly to anchor turbines.

Offshore wind farms present a promising source of unlimited energy. According to an article written by TreeHugger.com, there is as much potential wind power off our coasts as the current capacity of all power plants in the U.S. combined. [Continue Reading →]

Solar Powered Ships

The race to go green is on in the shipping industry. Not only is the price of oil soaring, but more and more stress is being put on the shipping industry to decrease its carbon emissions and its harmful affects on the global environment. This has led shipping companies to turn to sources of a renewable energy to power their vessels.

Two Japanese companies have taken the initiative to tackle this important issue saying that they plan to begin work on the first ships to have propulsion engines partially powered by solar energy and they could be ready as soon as 2010. According to an article in Reuters:

Japan’s biggest shipping line Nippon Yusen KK and Nippon Oil Corp said solar panels capable of generating 40 kilowatts of electricity would be placed on top of a 60,000 tonne car carrier to be used by Toyota Motor Corp.

The solar panels would help conserve up to 6.5 percent of fuel oil used in powering diesel engines that generate electricity at any given moment.

Solar panels for an average home usually generate 3.5 kilowatts of electricity.

The system is expected to help reduce carbon dioxide emissions by 1-2 percent, or about 20 tonnes per year, said Hideyuki Dohi, general manager at Nippon Oil’s energy system development department.

Nippon Yusen will invest about 150 million yen ($1.4 million) in the solar panel system to be designed by Nippon Oil.

Solar panels capable of generating several kilowatts of electricity have been used on large vessels before but their use has been limited to power for the crew’s living quarters.

While this system would have to be implemented on a large scale to have any significant impact on emissions from the industry as a whole, it is a step in the right direction and could potentially persuade other companies to follow.
