How To Build A Wind Turbine Generator At Home

How To Build A Wind Turbine Generator At Home – This should be a great time to be active in the wind energy sector, especially in Europe. Governments here have long promoted offshore wind projects, and those efforts have gained momentum since Russia began cutting natural gas supplies in its war against Ukraine.

“We want clean, cheap energy and local electricity,” EU President Ursula von der Leyen said in August.

But European wind turbine manufacturers, a jewel of the region’s green energy industry and a source of manufacturing expertise, are reporting losses and layoffs. Their problems stem from ongoing supply chain issues and competition from Chinese manufacturers, which could ultimately hamper Europe’s and even the world’s push to rapidly develop zero-emission energy sources.

This month, Madrid-based Siemens Gamesa Renewable Energy, a leading maker of offshore wind turbines, reported a loss of 940 million euros ($965 million) for the year. The company announced a cost-cutting program that is expected to result in the loss of 2,900 jobs, or about 11 percent of its workforce.

Vestas Wind Systems, the world’s largest turbine maker, recently reported a third-quarter loss of 147 million euros (about $151 million).

General Electric, a major manufacturer of wind turbines in the United States and Europe, is also struggling with its clean energy business. The company said last month that the renewable energy unit is expected to post a $2 billion loss this year.

The industry faces a number of challenges, including rising material and freight costs, as well as logistical challenges, some of which are a legacy of the pandemic. As a result, pre-negotiated prices for turbines, which can cost millions of dollars and reach hundreds of billions for large offshore wind farms, can lead to significant losses for manufacturers in supply.

“Every time we sell a turbine, we lose 8 percent,” Vestas CEO Henrik Andersen said in an interview.

At the same time, the race to build bigger, more powerful turbines led manufacturers to spend millions of dollars on new models, but not sell enough cars to cover the costs.

There are signs of growing competition from China, where domestic turbine manufacturers that have been operating in the Chinese market for years are starting to sell their machines abroad. Some Western turbine makers fear a repeat of the bitter experience with solar panels, a technology first developed in the West but now largely dominated by Chinese and other Asian manufacturers.

“They’re in trouble,” Andrei Liko, senior wind analyst at consultancy Wood Mackenzie, said of Western turbine manufacturers. “We’re talking about a huge loss for the industry.”

The poor financial performance raises questions about the future of the wind industry in the West and whether the highly ambitious plans of governments and energy companies to develop large wind farms in Europe and the United States will come to fruition.

Siemens Gamesa CEO Jochen Eckholt said in an interview that it needs to find money to manufacture, build and install turbines, including on the East Coast of the United States, to help countries meet their climate goals for reducing carbon emissions. enough

Siemens Gamesa’s major shareholder, Siemens Energy, is offering to buy a third of the turbine maker in a bid to cut costs and tighten control, lamenting recent losses.

European officials have also criticized parts of the Biden administration’s anti-inflation law that encourage domestic investment, fearing that important clean energy incentives will drive manufacturers away from the continent. However, European renewable energy leaders whose companies plan to expand in the United States saw a lot in Biden’s program.

Mr. Eckholt said in a recent telephone interview with reporters that Europe would be wise to take such measures. “I think it’s also very important that we maintain an adequate knowledge, manufacturing and labor base in Europe,” he said.

While Chinese manufacturers have had modest success outside their home country, analysts say they have used China’s large trade volume to improve manufacturing skills and train a large workforce to rival their Western rivals.

“Europe is now facing the real possibilities of the European Union. “The energy transition will be driven by China,” warned Siemens Gamesa in a recently published document asking for help from European governments.

According to Mr. Lico, Chinese companies already produce 70 percent of the components that make up the turbines used in the West. “China is the hub of the global wind supply chain,” he said, referring to component manufacturers.

Vestas’ Mr. Anderson attributes much of the industry’s problems to competitors selling cars at low prices to win orders. “I think the industry needs to wake up to our responsibilities here,” he said, adding that some equipment manufacturers are “selling turbines at profitable prices.”

The problems stem from European governments demanding more wind farms. The European Union recently increased its wind generation targets by the end of this decade, nearly tripling the amount it had at the end of last year.

While companies have built huge wind farms off Europe’s coasts and governments have leased large amounts of underwater land this year, particularly in Scotland, leaders say political leaders need to speed up approvals. These projects could take a decade to produce clean energy. In addition to dampening industry profitability, the delay delays environmental benefits and offers little benefit to countries seeking alternative energy sources to Russian gas.

Executives say a tax levy recently announced in Britain and proposed by the European Union to benefit electricity producers, including wind farm operators, will increase uncertainty for their customers.

“Pardon the language,” said Mr. Anderson. “Adjusting the targets for 2030 and 2040 may be a bit silly, as it will not solve the current energy crisis in Europe.” Ninilady 1500w Wind Turbine 12v 24v 48v 3 Phase Ac Wind Generator With Hybrid Mppt Controller 5 Blades Windmill (48v With Hybrid Controller)

To achieve this goal, the current rate of installation needs to be significantly accelerated, analysts say. Getting up to speed can be difficult for an industry in retreat.

Europe faces a dilemma: support domestic turbine production, prolong dependence on fossil fuels, or switch to alternative sources of equipment, Mr Liko said. This is “a matter of first priority,” he said.

Power for my off-grid cabin comes from solar and wind energy stored in four 6-volt golf cart battery banks connected to a 12-volt system. A charge controller and battery monitor ensure that my system is not under- or over-charged. The whole dog is under $1000, I have lights, fans, a TV and stereo, a fridge, and a disco ball that goes up for special occasions.
