頭一遭,美國海上風電開發者最近作出自願性承諾,在加速發展中大西洋海上風電設備同時,會採取必要措施來保護瀕臨滅絕的北大西洋露脊鯨。
專家估計,北大西洋露脊鯨在經過幾百年的補鯨活動後,數量只剩約350~400隻。該物種目前受國際及美國法律保護。近期研究認為族群量有略微上升的趨勢,但北大西洋露脊鯨仍處於極度瀕危狀態。
基於聯邦制訂的保護建議,美國保育法律基金會、美國野生動物基金會、環境美國及美國自然資源保護協會與「NRG藍水風能」(NRG Bluewater Wind)和麻州風角電力公司的擁有者「深海風能(Deepwater Wind Energy Management, Inc.)」兩家公司合作訂定協議;這兩家公司已經取得所需的許可,將在Nantucket Sound建立美國第一個海上風力發電場。
這份協議的共同目標是在中大西洋區建立乾淨、可再生的海上風力能源,以降低燃燒石化燃料的碳排及對海洋、野生動物與氣候的威脅。
協議雙方起草了一套保護措施,這兩個風電開發商未來四年將在聯邦政府指定從新澤西州延伸到弗吉尼亞州的中大西洋風能區域執行。
藉由臨時塔上的設備蒐集聲音可用來測量天氣狀況及水底地質調查。這份協議同意在風電場勘探行為中減少或避免聲音對鯨魚的干擾──水下聲音干擾可能會影響鯨魚彼此溝通、遷移行為及覓食。
這份協議於12月12日送達美國海洋能源管理、監督和執行局,該局負責監管海上可再生能源發展。
羅得島保育法律基金會副總裁Tricia Jedele表示:「我們和這些主導部門共同的目標就是儘速開始海上風力發電,作為對抗氣候變遷的工具。」「必須澄清的是,為海上風力發電移除障礙並不代表抄捷徑。這些風力開發者和科學家與環保團體成員共同制訂這些新的露脊鯨保育措施,並將這些措施納入他們的業務規劃中。這是既可在大西洋保護瀕臨滅絕的露脊鯨又能促進海上風電的進展的雙贏協議。」
美國野生動物基金會可再生能源與野生動物專案經理Justin Allegro認為,乾淨能源和露脊鯨族群的成長,都是重要的。「目前氣候變遷對野生動物是個很大的威脅,而我們迫切的需要轉換能源來源為乾淨的能源,比方說是風力發電。這份協議讓能源開發公司可協助保育瀕絕的露脊鯨。」
美國自然資源保護協會的Kit Kennedy表示,「這份獨一無二的協議,將幫助業界領導者更迅速的捕捉中大西洋的風力潛能,同時保護極度瀕絕的物種。這些公司展現強大的領導力。氣候變遷議題危及了全球海、陸域的生物,而轉換至乾淨能源是我們能對抗氣候變遷的方式。有了這樣積極的行動,負責任的美國風能可作為永續能源的發韌、提供美國目前需要的工作機會,並同時保育海洋生物。」
深海風能執行長Jeffrey Grybowski領導產業建立這份協議。他表示:「海上風能是我國長程能源安全很重要的一部份;我們擁有巨大的能源蘊藏在海上,發展它有助於保護我們的環境並保護如北大西洋露脊鯨在內的物種。」
深海風能通訊主任Mark Rodgers表示:「和這些頂尖的環保團體合作是我們的榮幸,他們強烈支持可以守衛北大西洋露脊鯨的美國海上風力發展。」
北大西洋露脊鯨會到美國東南海岸度冬與生產,夏天,牠們在新英格蘭海域及加拿大南境新斯科舍省覓食與餵養幼鯨。牠們最常使用的區域之一為靠近開普風力發電場(Cape Wind development)預定地的麻州灣(Massachusetts Bay)和開普角灣(Cape Cod Bay)。
9月,由荷蘭籍工程及地科團隊操作的兩艘駁船開始為開普風力發電場址的130隻風機進行水下環境測試。
新的協議提供額外的保護措施,藉由限制氣象塔設備及其他活動於鯨魚南來北往遷移高峰時的運作來降低對鯨魚的威脅;調整為在鯨魚活動頻度降低的其他時間運作。
在風電場預定區加強鯨魚活動人為監測、及觀測到鯨魚活動時限制調查作業皆有助於鯨魚生存。
繁殖季時在該區使用低噪音的設備與技術及對船隻設定速限都有助於提供鯨魚友善的環境。
參與此項協商談判及簽訂過程的Scott Kraus博士表示:「我很高興見到負責風電開發者對露脊鯨議題的正面回應。」他服務於新英格蘭水族館,同時為北大西洋露脊鯨頂尖專家、政黨的諮詢科學家。他說:「許多風力場設在北大西洋露脊鯨的遷移廊道上,這項協議有助於降低開發對復育露脊鯨的衝擊。」
這項協議也得到其他環保團體如國際動物福利基金會、非營利海洋保育組織Oceana、美國山巒協會及南方環境法律中心的支持。
過去十年來,歐洲的海上風力發電提供越來越高的供電比例,而美國還沒建立任何一座海上風電場工程。美國的大西洋海岸蘊藏可說是全世界最好的海上風力資源。
開發大西洋海岸的一小部分風力能源可生產提供1400萬個美國家庭所需的乾淨能源,並在東岸創造超過2千億美元的新經濟活動。
In an unprecedented collaboration, offshore wind developers have agreed to voluntary measures that will protect critically endangered North Atlantic right whales, while expediting responsible offshore wind development in the Mid-Atlantic.
Experts estimate that just 350 to 400 individual North Atlantic right whales remain after centuries of whaling. The species is now protected by national and international law. Recent analysis of sightings suggests a slight growth in population size, but, North Atlantic right whales remain critically endangered.
Building upon proposed federally mandated protections, the Conservation Law Foundation, the National Wildlife Federation, Environment America and the Natural Resources Defense Council worked with NRG Bluewater Wind and Deepwater Wind Energy Management, Inc., the owner of Cape Wind in Massachusetts, which has received all needed permits to build the nation’s first offshore wind farm in Nantucket Sound.
The agreement grew out of a shared objective to develop clean, renewable offshore wind energy in the Mid-Atlantic region to reduce carbon emissions from burning fossil fuels that threaten the ocean, wildlife and the climate.
The two sides have drafted a set of protective measures that the two wind developers will implement over the next four years in areas designated by the federal government as Mid-Atlantic Wind Energy Areas, stretching from New Jersey to Virginia.
The agreed measures protect the whales by reducing or avoiding sounds from exploratory activities that developers use to determine where to build wind farms. The sounds might be generated by the construction of temporary towers to measure weather conditions and underwater surveys that assess the geology beneath the ocean floor.
Underwater acoustic disturbances can disrupt whale communication, migration and feeding.
On December 12, the agreement was sent to the federal Bureau of Ocean Energy Management, which oversees offshore renewable energy development,
“We share with these leading developers a common objective to get offshore wind up and running as quickly as possible as a key tool in the fight against climate change,” said Tricia Jedele, vice president and director of Conservation Law Foundation Rhode Island.
“To be clear, removing obstacles to offshore wind doesn’t mean cutting corners. Indeed, these companies have worked pro-actively with scientists and members of the environmental community to develop these new right whale protections and build them into their business plans. It’s a win-win agreement that both enhances protection for critically endangered right whales and advances offshore wind’s progress in the Atlantic,” said Jedele.
Justin Allegro, renewable energy and wildlife program manager at the National Wildlife Federation, said both clean energy and a thriving right whale population are important.
“Climate change is the single biggest threat to wildlife today and we urgently need to transition to clean energy sources like offshore wind,” said Allegro. “This collaborative agreement between key ocean stakeholders helps ensure these Atlantic offshore wind industry leaders can develop while protecting critically endangered right whales.”
“This first-of-a-kind agreement will help industry leaders more quickly capture the enormous potential of wind blowing off the Mid-Atlantic coast, while protecting a critically endangered species at the same time,” said NRDC Clean Energy Counsel Kit Kennedy. “These companies have shown great leadership. Climate change is the single biggest environmental threat to all life on Earth – on land and in the water – and the only way we can rise above it is by switching to clean energy sources. With proactive action like this, responsible American wind energy can start delivering the sustainable energy and jobs our country needs right now, while safeguarding marine life.”
Jeffrey Grybowski, CEO of Deepwater Wind, led the industry in developing the agreement. “Offshore wind energy is a critical component to our nation’s long-term energy security. We have an enormous energy resource right off of our coast and developing it will help preserve our environment and protect species like the North Atlantic right whale,” he said.
“We are pleased be working with these leading environmental organizations who have been forceful advocates for launching America’s offshore wind industry on this measure to help safeguard North Atlantic right whales,” said Mark Rodgers, communications director at Energy Management.
North Atlantic right whales migrate from wintering and calving areas in coastal waters off the southeastern United States to summer feeding and nursery grounds in New England waters and north to Nova Scotia, Canada. One of their highest use areas is Massachusetts Bay and Cape Cod Bay, near the Cape Wind development.
In September, two barges operated by a Dutch-based engineering and geoscience consulting firm began underwater environmental testing for every one of the 130 wind turbines planned for Cape Wind.
The new agreement reduces the threat to right whales by limiting weather tower construction and other activities during the peak migration season, when whales travel through the mid-Atlantic region between southern calving and northern feeding grounds. During other times of the year, when the whales frequent the area less, the activities may take place with additional protective measures.
Enhanced real-time human monitoring for whale activity in the site area and restriction of activities to daylight hours when whales can be spotted, will help the giant mammals to survive.
The use of noise-reducing tools and technologies will help, and a lower speed limit for vessels in the area during migration times will help the whales avoid ship strikes.
“I was pleased at the responsiveness of the wind farm developers to right whale issues,” said Dr. Scott Kraus of the New England Aquarium, one of the leading authorities on the North Atlantic right whale, science advisor to the parties, participant in the negotiations and a signatory to the letter.
“Many of the wind farm areas occur in the migratory corridor for this endangered species, and this agreement should help minimize the effects of development on the continued recovery of right whales,” said Dr. Kraus.
The agreement also has the support of such other environmental organizations as the International Fund for Animal Welfare, Oceana, the Sierra Club and the Southern Environmental Law Center.
In Europe, offshore wind projects have been providing an increasingly large portion of power for over a decade. In the United States, not a single offshore wind project has yet been built, but the U.S. Atlantic coast has some of the world’s best offshore wind resources.
Harnessing just a fraction of the Atlantic coast’s offshore wind resources could generate enough clean electricity to power to about 14 million U.S. homes, while creating over $200 billion in new economic activity along the coast.
