On this day, April 4, 2020, New York state got 1,000 ventilators after the Chinese government facilitated a donation from billionaires Jack Ma and Joseph Tsai, the co-founders of the Chinese e-commerce giant Alibaba. Gov. Andrew Cuomo said that the state of Oregon had volunteered to send 140 more breathing machines. New York had 113,700 confirmed cases as of this morning. At least 3,565 had died in New York and more than 115,000 had tested positive.
14 Gigawatt Wind Project Under Review
Oregon’s 2022 Biennial Energy Report states on page 11 that Oregonians consumed 53.7 million megawatt-hours (MWh) of electricity in 2020, from both in-state and out-of-state sources, which equates to 73,511.3 MW of production over a one year period (53,700,000 MWh / 730.5 hours per year). During 2020, the energy resource mix was comprised of hydro (38.9%), coal (26.5%), natural gas (21.5%), land-based wind (7.0%), nuclear (3.5%), and other forms incl. solar, biomass, and geothermal, etc. (2.6%).
It is understood that the projected output of Oregon’s offshore wind farms in both “call areas” will be 14 gigawatts, requiring dozens of specialized vessels manned with expert technicians.
Adding 19 percent of Oregon’s average annual needs to the grid begs the question of whether this gargantuan project’s benefits will outweigh its gargantuan costs - costs that Oregonians will be required to shoulder via state and federal taxation, as capital outlays and ongoing cost of operations and maintenance for this ‘seasonal’ energy source are fully accounted for.
The break-even point when delivered energy values exceed the project’s costs are at issue, assuming the equipment can last long enough for the ROI to ramp out of the red. Upon end of life, decommissioning and recycling wind-turbine components require specialized planning; in particular, blade disposal poses a formidable challenge due to their size and composition.
It is understood that 18 wind turbines and foundations will be located beyond 13.8 miles (12 nautical miles), utilizing 6,800 miles of additional subsea cable; however, obvious impacts to bird habitats (survival rates) will be felt. Several marine mammals will be harmed, as “gray whale migratory routes are most dense within 6.9 miles from shore, Southern Resident killer whale habitat occurs 11.5 miles from shore along the Oregon coastline to 656 feet (200 meters) water depths, and humpback whales are generally concentrated in water depths up to 328 feet.”
Land-based wind turbines have a typical lifespan of up to 20 years while routinely maintained semiannually , yet the Pacific Ocean is historically one of the most powerfully destructive environments on the planet.
When inevitable breakdowns, failures, and fluid leaks during its lifespan are considered, maintenance more frequently than twice per year will be required; furthermore, the inevitable leaks and failures will be significant when comparing ‘viable’ turbines in extreme, salty environments to well-documented reliability issues of more common, terrestrial wind plants. Wind Systems Magazine, 2/15/2024
Produced outputs are seasonal due to unpredictable wind speeds and thermal effects on energy lost during transfers over long distances; wind plant performance tends to be highest during Spring months and lowest during mid- to late-Summer months, when grid loads peak due to high air conditioning demands and other electrical-cooling system burdens
NOTE: There is a time-sensitive opportunity to voice opinions to the federal government about the proposed offshore wind energy project near Coos and Curry Counties where comments are due by Friday, March 15, 2024: Notice of Intent To Prepare an Environmental Assessment for Commercial Wind Leasing and Site Assessment Activities on the U.S. Outer Continental Shelf Offshore Oregon
