First Phase of Giant London Array Offshore Wind Farm Underway

The first phase of what will be by far the world's largest offshore wind farm, the London Array, has begun construction. The first two 3.6 MW turbines were installed on January 27 and 28 and will be generating electricity by March.

The first phase will have a total of 175 turbines and lowest prices on viagra should be completed by the end of the year. At that point, the London Array will have a capacity of 630 MW. Phase two will begin shortly after, ultimately bringing the wind farm to a 1 GW capacity, capable of powering 750,000 homes.

Wind power capacity is adding up fast in the get cialis prescription U.K. The world's current largest offshore wind farm, the Walney project off the coast of viagra online overnight next day shipping Cumbria, just finished opened today. The 100-turbine wind farm has a capacity of 367 MW and will be able to power 320,000 homes.

Next up will be the 133-turbine, 500 MW Greater Gabbard offshore wind farm that should be completed before the end of the year.

UK Installing "Wind Farm Friendly" Radar

New radar facilities are being installed in Great Britain in order to "unlock" large sections of potential wind farm area for development. Because of potential interference, dozens of wind farm projects have been blocked by the Ministry of Defence (MOD). But now, the MOD has tested these new radar systems, and is satisfied that they will not suffer adverse effects from wind turbines.

One recent installation of a new Lockheed Martin air defense radar has let to the Ministry withdrawing its objection to five offshore wind farms that had been stalled over the issue. Wind farm developers are underwriting the cost of these new radar systems, but that investment could allow them to build as many as 4 gigawatts of additional wind farms.

Atlantic City Offshore Wind Farm Could Start Construction in the Fall

Offshore wind farm projects have finally been receiving approval in the U.S., but none have started construction yet.  A 25-MW project planned for off the coast of Atlantic City could step up and break ground first if approval comes in March.

The developers of the project, Fisherman's Energy of Cape May, have announced that they're ready to start construction in the fall if approval is given from the mexico levitra no prescription New Jersey Board of Public Utilities.  The five-turbine wind farm will be capable of powering 10,000 homes and could be finished and feeding electricity to the grid by Labor Day 2013.

The Atlantic City project could be the first constructed of a series of wind farms planned as part of the East Coast wind corridor, stretching from Virginia to New York City and with major financial backers like Google and grants from the federal government.



Smaller Wind Farms More Cost Effective Than Bigger Ones

It seems logical that, like buying in bulk at Costco, the more turbines in a wind farm, the lower the cost per turbine and the lower the cost of electricity for that project, but the U.S. Department of generic levitra overnight Energy found that when it comes to wind farms, smaller is i recommend generic levitra from canada actually cheaper.

A new report on the wind technology market from the DOE finds that the cost per kW of electricity for a wind farm is actually at its lowest in the 5 to 20 MW range, not the biggest 200 MW and above wind farms, like one would think.  The probable reasons for this come down to added costs associated with the levitra medication biggest of wind farms that don't apply to smaller ones.

  1. Wind farms above 20 MW have to go through the Federal Energy Regulatory Commission, which can cost extra time and money for developers.
  2. Large wind farms need special financing which can only be handled by a select few large firms that likely charge a premium for their services.
  3. The biggest reason could be that the largest of projects require the addition of new transmission lines, which can be extremely expensive.

This finding may encourage smaller, more affordable projects on a local level, much like how distributed solar projects have really taken off compared to larger solar farms.  Communities could own their own wind farm and reap the cost and environmental benefits.  Small projects may even want to take advantage of vertical axis turbines that have been found to produce more electricity in less space than horizontal axis ones.

Vermont Plans to Get 90% of Energy from Renewable Sources by 2050

Vermont's Department of Public Service has released a new Comprehensive Energy Plan that raises its renewable energy target to 90% by 2050, a huge leap from the 25% by 2050 target set in 2008. 

The plan calls for a mix of new renewable energy projects, energy conservation, gains in residential and commercial energy efficiency, and developing plug-in vehicle infrastructure.

Vermont has a bit of an advantage going into this goal since it has the lowest energy demand in New England and also has no coal-fired power plants.  The Vermont Yankee nuclear plant that supplies one-third of official canadian pharmacy its electricity is closing next year, so the state is aggressively pursuing renewable energy, mainly solar and wind power, to replace it.
