Getting U.S. Offshore Wind Farms Built: Integrating Knowledge from the European Market

North American Clean Energy

At the end of 2012, the estimated installed capacity of offshore wind exceeded five gigawatt (GW). The majority of this energy lies in European waters with some in China and Japan.  In the U.S., a number of offshore projects are in advanced stages of development but installation has yet to occur. Some common challenges include: high development and construction costs, obtaining accurate predictions, grid capability, and constrained supply chains. It remains possible to complete projects with minimal delays and within the overall budget allowance. The success of a project depends on the willingness to seek independent advice, use of proven technologies and supplies, and realistic provisions for construction costs and timelines. Although offshore wind power in North America Is still in the planning stages, several committed companies are pushing for this to become a reality.

A Floating Wind Tower in Launched in Maine

New York Times: 31 May 2013

Offshore wind had not yet caught on in the United States due to the steep cost of erecting a tower in the water, but at the University of Maine, researchers have tried another cheaper approach by launching a floating wind tower which is the first wind installation in the United States. Its 20 Kilowatts has enough capacity to fuel only a handful of large homes during a summer day but this is only the beginning. Two advantages distinguish the new project from onshore ones: it can catch the strong breezes on a sunny summer afternoon and it can produce more electricity than onshore towers. The floating wind tower sits on three concrete tubes.  It is one of seven projects under a $ 168 million government aided program.

Energy-smart, ‘green’ practices the new must-haves in commercial buildings

The Advocate: 30 May 2013

When companies look for a building location, one of their first priorities usually is location. However, factors like reduced energy bills and having equipment that make a smaller impact on the environment are rising on companies’ priority list. Stamford, Connecticut is joining the Commercial & Industrial Property Assessed Clean Energy (C-PACE) program, which will give building owners in the state’s third-largest city an ally in their efforts to be “green.”

Japan’s Big Jump Forward

Solar Today: April 2013

Growth in renewable energy, especially solar, has been proceeding at a frenetic pace since Japan initiated its generous feed-in tariff on July 1, 2012. This incentive enticed everyone, including oil companies, to participate. Japan is expected to be the world’s third biggest solar market this year, right behind China and the United States/Italy. The goal is for renewables to provide 40 percent of Japan’s electricity by 2030.

Articles of Interest: Sept 23 – Oct 4, 2011

windmill and smokestacksHow Will We Fuel the Future?

September 23, 2011

Fareed Zakaria in his op-ed piece, NYT, ‘Fueling the Future’ analyses the current energy crises the world faces at this moment. His analysis goes further than the discussion put forward by Daniel Yergin in his book “The Quest, Energy, Security, and the Remaking of the Modern World.” Zakaria argues that though technological advances have been made in terms of solar,wind and biofuel, we still lack sufficient technology to store the harvested energy and is expensive compared to coal. Even though nuclear energy remains the most viable carbon-free technology, the public opinion againstnuclear power makes it impossible for governments to pursue them. In his conclusion, Zakari says that while raising carbon tax is a possible solution,he also highlights the need to invest in research on green technology that will continue to make it cheaper than the production of energy from coal. This will help ensure that renewables are adopted by emerging developing countries as China and India, both of whom continue to have a large dependency on coal.

 

A Way to Make Motor Fuel Out of Wood? Add Water

September 27, 2011

 

A Georgia company, Renmatix, has been experimenting with a technology that

treats agricultural waste and turns it into vehicle fuel and other chemicals

using compressed water heated to a very high temperature. If it works, the

technology could reduce reliance on oil imports for gasoline in favor of a

cleaner-burning and less expensive source of energy. More importantly, as the

supply of cellulosic biomass, or wood chips, is far larger than the amount of

corn available for making ethanol, it does not involve diverting resources from

food production.


 

Blue Mountain Geothermal Plant, NV

A US-Backed Geothermal Plant in Nevada Struggles:

Unpredictability of Renewable Technology

October 2, 2011

A Nevada Geothermal Power plant in a remote desert location in northern Nevada is struggling with the debt after encountering the problems with power output. The geothermal plant generates only 35megawatts compared to its predicted output of 45megawatts when the funds were approved. This uncertainty of power output and time taken to construct geothermal installation makes them much riskier investments compared to solar and wind. The federal government investment in the plant stands at $79 million as loan guarantee and $66 million in the form of grants.

 

Bullitt Center in Seattle
Bullitt Center in Seattle, as proposed

The Self-Sufficient Office Building

October 4, 2011

A six-story $30million Bullitt Center in Seattle is set to be the greenest commercial structure in the world. The center will generate its own power, supply and treat its own water including rainwater while it will also avoid using hazardous ‘red listed’ materials as lead and cadmium. The energy consumption is estimated to be one-forth of the typical building of same size while the designs of the building will ensure energy efficiency. The key however, is making sure that the new tenants are more environmental conscious.

Informal Workshop on Renewable Energy in the Context of the Green Economy

Tuesday 28 June 2011

The Permanent Missions of the Republic of Korea and Denmark to the United Nations hosted an informal workshop on Renewable Energy in the context of the Green Economy with presentations of the private sector. The workshop served as a platform for discussion of how implementation of renewable energy technologies can contribute to the transition to a new era of sustainable energy and development. The workshop generated recognition that renewable energy can be a cost-effective, feasible policy alternative in the transition to a new era of the green economy.
