Wind farms are not always popular

People complain about pollution, about nuclear, about so many things. But when efforts are made to promote sustainable energy such as through wind farms, people again complain. It is “disturbing the landscape”. So, we should also destroy the windmills in Belgium and Holland?

I personally don’t feel “offended” by wind turbines, they are rather elegant. The complaints about noise and hurting birds are also exaggerated. If people love birds then they should not have windows because many birds fly right into those, being misled by the reflection. Just recently a lovely bird crashed into my Beijing window. I tried to take care of it but I am afraid its legs were paralyzed and it would not recover.

Floating wind farms

A newer technology, offshore floating wind farms might accommodate some of the complaints.

Offshore Wind Farms See Promise in Platforms That Float

What are floating wind farms?

Right now, almost all offshore wind turbines require fixed platforms built into the seafloor. Floating turbines, with anchors, would mean new flexibility in where wind farms could be placed, with potentially less impact on marine life. Also, less opposition from the human neighbors on shore.
Developers can locate the farms farther out at sea, where they would not be visible from land, and their anchoring mechanisms have a smaller, more flexible footprint than the embedded foundations of conventional wind turbines. That could result in less environmental disturbance and easier transportation and installation.

Conventional offshore wind developments, with foundations deep beneath the ocean floor, are increasingly common in Europe. But partly because of public opposition, fixed offshore turbines are just starting in the United States, with the first such farm set to begin operation by November near Rhode Island.
Statoil, the Norwegian oil and gas giant, is already developing what could become the first commercial-scale floating wind farm, off the coast of Scotland.
Trident Winds, a company based in Seattle, is pursuing a federal lease to install about 100 turbines more than 30 miles out from Morro Bay on the central California coast.

With the floating concept, you can use the same turbine everywhere, so you can see the potential for mass production. The beauty of this is, every 20 years — which is typically when the turbine reaches the end of its life — you can tow this back to shore, put a new turbine on and take it back.

Canadian Embassy event

The Embassy of Canada organized another “Canada in Conversation” event on the viability of carbon capture and storage. The seminar was chaired by Ms. Cindy Termorshuizen, Chargé d’Affaires of the Embassy.
It took place on 22 September 2016 at the Embassy.
The Saskatchewan Premier Brad Wall gave a keynote address and participated in a panel discussion featuring Mike Monea, SaskPower’s President of Carbon Capture and Storage Initiatives, along with Chinese experts, chaired by Ms. Xu Qinhua of Renmin University.
A networking reception at the Official Residence followed the panel discussion.

Background on carbon capture and storage

Coal is an energy source that generates about 40% of the world’s electricity and about 25% of its greenhouse gas (GHG) emissions. As global population increases and developing countries continue to industrialize and increase their standard of living, carbon dioxide (CO2) emissions will continue to rise. It is critical to find ways to reduce GHGs and mitigate the impacts of climate change, while ensuring sustainable economic growth.

One key option for the near term is carbon capture and storage (CCS), a technology that can capture, transport and safely store up to 90% of the CO2 emissions produced from coal and other fossil fuels in electricity generation and industrial processes – and stop it from entering the atmosphere.

Current CCS projects underway in the province of Saskatchewan, including the world’s first post-combustion coal-fired CCS project integrated with a power station, are positioning Canada as a global leader in turning the corner on climate change and developing clean technologies that recognize dependencies on energy derived from fossil fuels.

Carbon capture and storage: a Canadian success story

The presentation was pretty convincing, many like me are not always convinced underground storage works, the CO2 does not filter back to the service and it is economically doable.
Of course the Canadian project has some great advantages to make it work. They sell the gas to oil companies – who pay money – so they can use it to maximize oil recovery from their wells. And as Mike Monea explained, the oil wells work as perfect seals to keep the gas underground. Only a rather small part of the carbon is stored by the power plant.
There was a great interest from the Chinese side: I was one of the very few “foreigners” in the audience.

Wave energy in the world

By some estimates, the ocean’s endless motion packs enough power to meet a quarter of America’s energy needs. But wave energy technology lags well behind wind and solar power, with important technical hurdles still to be overcome.

America’s First Wave-Produced Power Goes Online in Hawaii (19 September 2016)
By Cathy Bussewitz, Associated Press
http://abcnews.go.com/Technology/wireStory/wave-produced-electricity-us-online-hawaii-42187915

Developers are still working to come up with the best design. Some buoys capture the up-and-down motion of the waves, while others exploit the side-to-side movement. Industry experts say a machine that uses all the ocean’s movements is most likely to succeed.
Also, the machinery has to be able to withstand powerful storms, the constant pounding of the seas and the corrosive effects of saltwater.
Wave energy technology is at about the same stage as the solar and wind industries were in the 1980s.
it is said the USA are a decade behind Europe. The European Marine Energy Centre in Scotland, for example, has 14 grid-connected berths that have housed dozens of wave and tidal energy devices from around the world over the past 13 years, and Wave Hub in England has several such berths. China, too, has been building and testing dozens of units at sea.

But while the U.S. government and military have put about US$334 million into marine energy research over the past decade, Britain and the rest of Europe have invested more than $1 billion, according to the Marine Energy Council, a trade group.

Wave energy in Hawaii

The U.S. Navy has established a test site in Hawaii, in Kaneohe Bay with hopes the technology can someday be used to produce clean, renewable power for offshore fueling stations for the fleet and provide electricity to coastal communities in fuel-starved places around the world.
Hawaii would seem a natural site for such technology. It is blessed with powerful waves.

Jose Zayas, a director of the Wind and Water Power Technologies Office at the U.S. Energy Department, which helps fund the Hawaii site, said the United States could get 20 to 28% of its energy needs from waves without encroaching on sensitive waters such as marine preserves.

Though small in scale, the test project near Kaneohe Bay represents the vanguard of U.S. wave energy development. It consists of two buoys anchored a half-mile to a mile offshore.
One of them, the Azura, which extends 12 feet above the surface and 50 feet below, converts the waves’ vertical and horizontal movements into up to 18 KW of electricity. The company involved, Northwest Energy Innovations of Portland, Oregon, plans a version that can generate at least 500 KW.

Green growth through wind and solar

After a boom in China, installing more wind and solar farms than anywhere else, China is reducing the pace of growth in an industry that has helped lower the costs of green energy worldwide.
There is a need to consolidate the industry, clean out the weaklings and improve the grid. Overall China will forge ahead.

China to Slow Green Growth for First Time After Record Boom – 23 September 2016

http://www.bloomberg.com/news/articles/2016-09-22/china-to-rein-in-green-growth-for-first-time-after-record-boom

A slowdown

Installations of new wind and solar farms are expected to drop 11% in 2017 from a record high in 2016.
China’s electricity demand is stagnating along with a pause in the nation’s economic expansion. The government has started re-calibrating subsidies for the business, a move that’s likely to hit the industry’s leading manufacturers, Xinjiang Goldwind Science & Technology Co. and Trina Solar Ltd.
China has been the single largest developer of the technology for eight years. Its demand for panels and turbines has pushed manufacturers to build factories throughout Asia, and the scale of its projects helped bring down the cost of electricity from low-polluting sources everywhere.
China’s wind and solar capacity will grow 41.8 GW in 2017, down from a record 46.9 GW in 2016.
I also believe that In the long run, there is no question where China is headed: China is committed to a low-carbon future.

Consolidation in wind and solar

Based largely in China, the solar manufacturing industry, has been opening new factories in Asia and elsewhere. Now the market is bracing for a glut, pressuring companies to cut prices and often leading to a merciless cut-out-the-weakest.
China needs to digest the wind and solar plants and connect those properly to the grid. A large percentage of the generated power is lost as the grid cannot or does not want to absorb it.

There is a new trend few have noticed in China: the government is now heavily promoting both wind and especially solar farms that are able to deliver 24/24 with storage capacities. That will be the technology of the future. I know some manufacturers of thermal solar who are doing brisk business as they deliver solar plants with storage, producing power in a more grid-friendly way.
The grid problems experienced in China are also becoming an issue in some European countries.
