The twenty-two wind turbines installed near the Sainte-Victoire mountain, in the Var, could they stop working or even withdrawn? On Wednesday, the Administrative Court of Appeal of Marseille has made a decision that constitutes a real victory for the opponents of this poor park that landscape painted so many times by Cézanne.

Everything’s coming up floating wind turbines. On Tuesday, the Biden administration announced plans to open up the waters off California to wind energy, signalling that the new technology is going to emerge.

“Today’s announcement reflects months of active engagement and dedication between partners who are committed to advancing a clean energy future,” Interior Secretary Deb Haaland said in a statement.

The proposal allows developers to site commercial-scale offshore wind farms in two locations, one in Morro Bay off central California and another off the coast of Humboldt near the state’s northern coast. Together, the administration said the locations could generate enough electricity to power 1.6 million homes. Remarkably, the scheme received support from the military, which uses California’s coast for testing and operations and has previously dismissed such plans. But though it cleared that major barrier, erecting offshore wind farms in the Pacific could also come with physical difficulties.

Biden boosts offshore wind energy, wants to power 10M homes

  Biden boosts offshore wind energy, wants to power 10M homes WASHINGTON (AP) — The Biden administration is moving to sharply increase offshore wind energy along the East Coast, saying Monday it is taking initial steps toward approving a huge wind farm off the New Jersey coast as part of an effort to generate electricity for more than 10 million homes nationwide by 2030. Meeting the target could mean jobs for more than 44,000 workers and for 33,000 others in related employment, the White House said. The effort also would help avoid 78 million metric tons of carbon dioxide emissions per year, a key step in the administration's fight to slow global warming. © Provided by Associated Press FILE - In this Sept.

Globally, most offshore wind has been constructed in shallow waters where turbines can be attached to the seafloor with concrete or steel. But the underwater topography along the West Coast drops off more quickly, which rules out anchored wind towers. So developers will have to come up with new ways to harness the power of the wind there.

Enter floating wind turbines, which are tethered with cables instead of stiff pilings. To stop them from drifting too far away, chains and weights can be added to anchors which can latch onto the ocean floor. In Wednesday’s announcement, the White House said “new floating offshore wind technology will be deployed in offshore California waters.”

This technology can allow developers to access faster and more consistent wind energy than their more fixed counterparts. It could also increase the world’s capacity to generate wind power since only an estimated 40% of offshore wind resources can be captured with fixed-bottom turbines.

Why investments in clean, renewable energy will avoid blackouts at a low cost

  Why investments in clean, renewable energy will avoid blackouts at a low cost In sum, not transitioning to 100 percent WWS increases costs, reduces jobs and increases energy insecurity. To eliminate air pollution deaths as fast as possible and to avoid 1.5 degrees Celsius of global warming since the 1800s, we need to transition all energy sectors to WWS quickly - with at least 80 percent by 2030 and 100 percent ideally by 2035-2040. We similarly need to eliminate non-energy emissions, which are about 10 percent of air pollution emissions and 20 percent of greenhouse gas emissions. Right now, we have 95 percent of the technologies we need. We do not need miracles.

This technology is relatively new. The world’s first floating wind farm started producing power in late 2017 off the coast of Scotland. Since then, roughly 20 more have been brought to fruition, but none are in the U.S. or operating at a commercial scale. Developers in Maine are currently pushing to bring a floating wind farm online, but it’s been a real uphill battle, so California might end up being the first in the nation to deploy this technology.

“While interest from the global industry will be unprecedented, West Coast development requires American ingenuity and innovation in next generation technologies that will create opportunities for engineering firms and skilled labor,” Liz Burdock, president and CEO of the Business Network for Offshore Wind, said in an emailed statement.

Developers are ready for the floating turbine future. In fact, several have already shown their interest in the region. A coalition including Magellan Wind and Orsted North America is gunning to construct turbines in California waters. And Trident Winds and EnBW North America have proposed a 1,000-megawatt floating farm near Morro Bay, though the companies have encountered opposition from the fishing industry, similar to what’s played out in Maine.

Clean megaprojects divide surprise group: environmentalists

  Clean megaprojects divide surprise group: environmentalists PORTLAND, Maine (AP) — Sprawling wind farms located off the coast. Hydropower transmission lines that cut through some of America's most beloved forests and rivers. Solar megaprojects of unprecedented size. As President Joe Biden's administration plans to fight climate change by weaning the nation off fossil fuels, these large-scale renewable energy projects are the source of conflict within a seemingly unlikely group: environmentalists. America's patchwork of environmental and conservation groups — encompassing players such as public lands advocates, animal welfare proponents and hunting organizations — have disparate opinions about new renewable energy inf

This week during a summit hosted by the Department of Energy, General Electric also announced that its researchers are working on a concept for a 12-megawatt floating farm. If the firm’s models and simulations pan out to provide proof of concept for the project, it may move forward with partners to build a prototype.

The floating wind market is expected to take off in the coming years, and the Biden administration wants to help it along. In a Tuesday statement, the White House said the Department of Energy “has invested more than $100 million in researching, developing, and demonstrating floating offshore wind technology.”

Once the Bureau of Ocean Energy Management officially sets aside the areas off the California coast for development and conducts an environmental analysis, the agency plans to auction off leases for the area to developers in mid-2022. If this new technology becomes a reality in the U.S., it could mean California becomes one of the largest global generators of wind power, and bring the U.S. closer to the Biden administration’s goal of reaching 100% no-carbon electricity by 2035.
