Oregon Wave Farm to Be First in United States to Harness Motion in the Ocean

It's been some time in coming, but the first wave farm in the United States just got licensed.

It's been some time in coming, but the first wave farm in the United States just got licensed. The 1.5-megawatt wave farm was built by Ocean Power Technologies, Inc. off the coast of Reedsport, Oregon.

Wave farming creates electricity by harnessing the kinetic energy of rising and falling ocean waters. The technology is still very new—the world's first commercial wave farm was built off the coast of Portugal and came online in 2008 (and was taken offline in 2009).

Like any form of energy generation, wave farming comes with concerns about environmental impact. Here, for example, are some concerns voiced by opponents of a proposed wave farm in San Onofre, California:

Environmental groups, which are broadly supportive of renewable energy projects, said putting the devices in the waters of San Onofre could harm marine life and potentially mar the view from the coastline. Surfers are worried it would dampen waves and alter seafloor terrain along a stretch of coast famed for its surf breaks. Sport-fishing groups said a wave farm could block off favored waters for sand bass, bonito and barracuda fishing.


It's also a new technology, and some are skeptical that it'll stand the test of time.

Some don't believe wave energy can work, said Onno Husing, director of the Oregon Coastal Zone Management Association.

"A lot of people who are very experienced with the ocean harbor a lot of doubt that anyone can in a cost-effective way put buoys in the water, harvest the energy, and not have them end up on the beach," he said.


OPT's setup is a buoy that floats up and down on waves, pushing a sort of piston up and down. The energy is transferred back to shore via underwater cabling. Learn more about wave power with this SmartPlanet primer.

Cancer is still the second leading cause of death after heart disease for both men and women. The American Cancer Society predicts that 2020 will bring almost 1.8 million new cancer cases and 600,000 cancer deaths, but there's also some good news. The American Cancer Society recently published a report in CA: A Cancer Journal for Clinicians stating the U.S. cancer death rates experienced the largest-single year decline ever reported.

Between 2016 and 2017, cancer death rates fell by 2.2%. While cancer death rates have been steadily falling over the past three decades, it's normally by 1.5% a year. Cancer death rates have dropped by 29% since 1991, which means that there have been 2.9 million fewer cancer deaths in the past three decades than there would have been if the mortality rate had remained constant.

The Australian bushfires have claimed 27 human lives, an estimated 1 billion animals are feared dead, and thousands of properties have been completely decimated.

The fires were caused by extreme heat and dryness, the result of 2019 being the country's hottest year on record, with average temperatures 1.52C above the 1961-1990 average.

The area hit hardest by the fires, New South Wales, also had its hottest year on record, with temperatures rising 1.95C above average.
