Massive wind farm comes online in Oregon – 845 megawatts of clean wind energy

The world’s third largest wind farm just started spinning its turbines in Oregon. Covering more than a thousand acres the 338 wind turbines will create 845 megawatts of clean energy 다운로드. All of that will be sent down to California for 20 years as part of an agreement with Southern California Edison – who is in need of clean energy to comply with state energy standards, 33% clean energy by 2020 다운로드.

The name of the project is Caithness Shepherds Flat and it cost $1.9 billion. During construction the project employed more than 400 workers and 45 of those will become permanent full-time positions 다운로드.

The wind farm will create enough energy to power 235,000 homes. Adding to the growing number of homes powered through clean energy. Recently, wind power in the United States passed the 50 gigawatt milestone, and this project should put that at 51 gigawatts 1945 스트라이커 3.

A substantial achievement but we still have a long way to go, the United States uses 3,900,000 gigawatts of energy.

American wind power reaches 50-gigawatt milestone

From the AWEA press release:

The 50 gigawatts (GW) online today means that U.S 원광 만세력 다운로드. wind turbines now power the equivalent of nearly 13 million American homes, or as many as in Nevada, Colorado, Wisconsin, Virginia, Alabama, and Connecticut combined 다운로드. In addition, 50 gigawatts (GW) of wind power capacity:

  • Represents the generating power of 44 coal-fired power plants, or 11 nuclear power plants 판타지 다운로드.
  • Avoids emitting as much carbon dioxide as taking 14 million cars off the road.
  • Conserves 30 billion gallons of water a year compared to thermal electric generation, since wind energy uses virtually no water 다운로드.

 

To put this into perspective, it is estimated that the United States used 3.9 million gigawatts in 2011 다운로드.

Now back to the good news, projects recently connected to the grid:

  • Pattern Energy’s Spring Valley wind farm, 30 miles east of Ely, Nevada (151.8 megawatts, or MW)
  • Enel Green Power North America’s Rocky Ridge wind farm in Oklahoma (148.8 MW)
  • enXco’s Pacific Wind project in Kern County, California (140 MW)
  • Utah Associated Municipal Power’s Horse Butte project in Idaho (57.6 MW)
  • First Wind’s Kaheawa Wind II wind farm in Hawaii (21 MW)
50,000 megawatts = 50 gigawatts

 

It took us a long time to hit 10 MW in 2006, then much less to hit 25 MW in 2008, and now, in 2012, we are at 50 MW 다운로드. The ramp-up continues all over the country as 39 states now have wind power feeding their grids. There is even good news on the “Made in USA” front with 60% of the sourcing coming from home, compared to 25% in 2005 다운로드.

Wind is cheaper than coal? — Fact checking this statement

The other day I heard in passing, “wind is now cheaper than coal.” If true, this symbolizes the holy grail of renewable energy. It would mean that a turning point for not only cleaner energy, but global warming, climate change, pollution, foreign oil dependence, and more 아마존 앱스토어 다운로드.

To fact check this, I pulled up the top 20 results from Google and narrowed them down to the below articles (most were duplicates pointing at these 5 stories) 프린텍 라벨메이커 다운로드.

Not at all definitive but it does give you an idea of the state of the industry. Just keep in mind that the prices may or may not include subsidies or tax breaks, which can drastically change the costs quoted below svn connector.

 

Jul 2012 – In India, wind is cheaper than coal in Indi (w/out subsidies) (Bloomberg Business)

The cost of wind power has dropped below the price of coal-fired energy in parts of India for the first time as improved turbine technology (from GE) and rising fossil-fuel prices boost its competitiveness, Greenko Group Plc (GKO) said 국민 보건 체조.

 

Mar 2012 – In Michigan wind is cheaper than coal (American Wind Energy Assoc 다운로드.)

The Michigan Public Service Commission (PSC) recently issued a report that finds that electricity generated from renewable energy sources, at an average cost of $91 per megawatt-hour (9.1 cents/kilowatt-hour), is almost one-third cheaper than the cost of electricity from a new coal-fired power plant ($133 per MWh, or 13.3 cents/kWh) 다운로드.

Further, the report notes, “The actual cost of renewable energy contracts submitted to the Commission to date shows a downward pricing trend apr 다운로드.

Nov 2011 – Google retires its initiative RE

It’s not clear here if Google feels this is already won and moving on, or if they have had enough and are quitting 다운로드. One thing is certain, Google invested nearly a billion dollars ($850 million) in renewable energy last year.

This initiative was developed as an effort to drive down the cost of renewable energy, with an RE<C engineering team focused on researching improvements to solar power technology 영어 동화 다운로드. At this point, other institutions are better positioned than Google to take this research to the next level. So we’ve published our results to help others in the field continue to advance the state of power tower technology, and we’ve closed our efforts.

Coal power plants are going offline, in favor of Natural Gas plants

“In the past year, coal plants have been facing a perfect storm of falling natural gas prices, a continued trend of high coal prices and weak demand for electricity,” Susan Tierney wrote in the report 인스타그램 mp3 다운로드.

Tierney wrote that those factors have combined to make coal a less desirable fuel source.

Coal-generated electricity has been waning over the past few years, dropping to its lowest level on record in March of this year, according to the U.S 오토 캐드 2014 다운로드. Energy Information Administration.

At the same time, natural gas-powered plants are becoming increasingly popular as the price of the fuel falls to record prices and few emissions emitted by natural gas 다운로드.

According to Doyle Trading Consultants, the trend is expected to continue as more than 41,000 megawatts from coal-fired power plants could be retired by 2020 공인단기. If true, the coal-fired fleet would be cut by 17 percent in eight years.

Myth = 100% of our energy cannot come form renewable sources

100% of Minnesota’s electricity generation needs can be met by wind and solar sources combined with improvements to the state’s electric grid system and energy efficiency policies, according to a report released today 다운로드.

Renewable Minnesota: Aanalysis of a 100% renewable-energy based electricity system for Minnesota

Researched and written by Dr 아츄 mp3 다운로드. Arjun Makhijani and Christina Mills of the Institute for Energy and Environmental Research (IEER) and Dr. M.V. Ramana of Princeton University.

Minnesota’s electricity sector currently accounts for over one third of the state’s greenhouse gas emissions 이카루가 다운로드. State policy is to reduce emissions by 80% by 2050.

“A significant change in electricity generation sources is clearly needed to achieve that goal,” Dr 다운로드. Makhijani explained. “Fortunately, wind and solar can provide 100% of Minnesota’s electricity. These currently available technologies also offer significant job creation and economic development opportunities.”

 

From Energy Self-Reliant States:

The notion that solar and wind energy cannot be the mainstay of an electricity generation system because they are intermittent is incorrect…it is technically and economically feasible to meet the entire 2007 electricity demand of Xcel Energy [in Minnesota] using only renewable energy generation combined with storage technology and energy efficiency improvements 다운로드.

The renewable energy mix would include approximately 13,000 megawatts of wind power and 4,600 megawatts of distributed solar PV…would pump more than $90 billion into the state’s economy and create 50,000 jobs 다운로드.

With the combination of new renewable energy and significant energy efficiency, electricity rates rise slightly but Minnesota ratepayers are held relatively harmless 다운로드.

The conventional notion of a “peak load” needs to be replaced in designing an electricity system with a high proportion of solar and wind energy…The crunch time may be during periods when the wind and solar supply are low relative to demand 다운로드.

Los Angeles has second most solar installations in California, behind leader San Diego

Los Angeles ranks second in the state in terms of the number of solar installations on residential, commercial and government buildings, with just over 4,000 projects installed dx11. Los Angles is also second in the state in terms of the total amount of solar electricity generated, measured in capacity, with 36 megawatts.

“The good news is Los Angeles is closing in on San Diego’s lead as America’s #1 solar city,” said Michelle Kinman 맥스큐 pdf.

Every megawatt of solar power installed in the Los Angeles area prevents the emission of nearly 700 pounds of smog-forming pollution per year.

A recent report by the Solar Energy Industry Association shows that California is home to over 3,500 solar companies that employ more than 25,000 people 무료 크리스마스 카드 다운로드.

In the past two years, Los Angeles has nearly tripled the amount of rooftop solar installations. From 1999 through 2009, Los Angeles installed just over 1,000 solar rooftop systems, totaling over 13 MW 다운로드.

Governor Jerry Brown has called for a significant expansion of California’s rooftop solar market by putting out a vision of installing 12 gigawatts (a gigawatt is 1000 megawatts, or twelve times California’s current solar rooftop market) by 2020 다운로드.

Los Angeles Unified School District at Richard E. Byrd Middle School in Sun Valley, which recently had a 362 kW solar system on a parking lot shade structure, which will save the District more than $1.6 million over the span of the 20 years and $60,000 in the first year 에이핑크 노래 다운로드.
