Introduction:The Role of Renewable Electricity
In recent years, the aviation industry has been actively seeking ways to reduce its environmental impact and transition towards more sustainable practices. One promising solution that has gained significant attention is sustainable aviation fuel (SAF).
SAF offers the potential to significantly reduce greenhouse gas emissions from aircraft, making it an essential component of the industry’s efforts to achieve carbon-neutral growth.
This article explores the crucial role of renewable electricity in the production and development of sustainable aviation fuel.
The Need for Sustainable Aviation Fuel:
Aviation is a vital mode of transportation, enabling global connectivity and economic growth.
However, traditional jet fuels derived from fossil fuels contribute significantly to carbon dioxide (CO2) emissions and other harmful pollutants. The urgent need to address climate change has propelled the search for alternative, sustainable options. Sustainable aviation fuel, made from renewable resources, offers a promising solution by significantly reducing lifecycle greenhouse gas emissions.
Renewable Electricity as a Key Enabler:
Renewable electricity plays a pivotal role in the production of sustainable aviation fuel. One of the most common methods of producing SAF is through the process of electrolysis, where water is split into hydrogen and oxygen using electricity.
This hydrogen can then be combined with carbon dioxide captured from various sources, such as biomass or industrial emissions, to produce synthetic hydrocarbon fuels. The use of renewable electricity ensures that the entire process is powered by clean energy sources, minimizing the carbon footprint of the fuel production.
Integration of Renewable Energy Sources:
The integration of renewable energy sources into the production of sustainable aviation fuel presents numerous advantages. Renewable electricity generated from sources like solar, wind, hydro, and geothermal energy not only reduces carbon emissions but also helps to address concerns related to energy security and price volatility.
By utilizing diverse renewable energy technologies, the aviation industry can establish a sustainable and resilient supply chain for producing SAF.
Collaborative Efforts:
To realize the full potential of renewable electricity in sustainable aviation fuel production, collaboration among stakeholders is essential.
Governments, industry leaders, researchers, and renewable energy providers need to work together to create a supportive policy framework, develop innovative technologies, and invest in infrastructure. Public-private partnerships can facilitate the scaling up of renewable electricity capacity and accelerate the commercialization of sustainable aviation fuel.
Challenges and Opportunities:
While renewable electricity offers significant opportunities for sustainable aviation fuel, several challenges need to be addressed. Scaling up renewable energy capacity to meet the increasing demand for SAF requires substantial investment and robust infrastructure development.
Additionally, optimizing the efficiency of electrolysis and developing advanced carbon capture technologies are critical for enhancing the sustainability of the entire process. Collaboration with other sectors, such as the power industry, can help overcome these challenges and drive the adoption of renewable electricity in sustainable aviation fuel production.

Impressive Levels of Stupidity
Without doubt, stupidity is part of Trumpism, but it’s only a part.
Meanness is also essential. People with any real compassion for others don’t have what it takes to be a member of the MAGA base.

As Aristotle said (plus or minus): Only people who do not seek power and qualified to hold it.
In retrospect, the United States hadn’t gotten burned too badly until Donald Trump came along.

Good Monday everyone.
You know … there is an old saying. When one door closes … another one opens. Well this week in wind energy … a whole lot of doors were swinging.
Let us start in Washington. For months … the Pentagon had quietly stopped reviewing wind energy project applications. More than a hundred and fifty onshore wind projects … stuck in limbo. The Defense Department claimed that drones in Ukraine had changed the game. Wind turbines … they said … could blind radar to incoming threats. So they hit the brakes.
But on Thursday … a federal judge said … not so fast. Judge Karin Immergut … a Trump appointee no less … issued a preliminary injunction. Resume the reviews … she ordered. Follow the law Congress wrote. The law gives the Pentagon seventy-five days for a preliminary review. As of late July … not a single one had been completed since the halt began in May. When government lawyers were asked to name one project they had reviewed … they could not name a single one. The judge told them plainly. If you want to change the rules … go ask Congress.
Now … while one arm of the government was being told to do its job … another arm was writing checks. German energy giant RWE … handed back its American offshore wind leases. New York. California. Louisiana. In return … the U.S. Department of the Interior cut RWE a check for one-point-two-two billion dollars. RWE is the fifth developer to walk away from American offshore wind under this administration. The company had spent more than a billion dollars on those leases. Years of planning. Investment. Partnership with federal agencies. But RWE said there is simply no path forward to permit these projects … for the foreseeable future.
So where does the $1.22B go? Nine hundred million dollars into Louisiana LNG. Three hundred million into natural gas turbine reservations. Fifteen gas peaking projects across the country. A company that came to America to build wind farms … is now building gas plants instead.
But here is the thing about RWE. They are not leaving the wind business. They are leaving American offshore wind. Globally … RWE operates eighteen offshore wind farms. Four more under construction. And nearly seven gigawatts secured in the United Kingdom’s latest auction. America said no. The rest of the world said … come on in.
And speaking of Europe … TotalEnergies … the French oil major … just bought Shell’s entire onshore renewables business in Europe. Four gigawatts of solar and wind. Five hundred megawatts already running or under construction in Italy and the Netherlands. Three-and-a-half gigawatts more in the pipeline across Italy … the United Kingdom … and Spain. And in the same breath … TotalEnergies sold a fifty percent stake in a one-point-two gigawatt European portfolio to KKR … for an enterprise value of one-point-eight billion euros. Build it. Sell half. Keep operating it. That is the model.
Now let us fly east … to India. GE Vernova just landed a hundred-and-sixty-three megawatt wind order from American developer Enfinity Global. Forty-three turbines. Three-point-eight megawatts each. Headed for the Fatehgarh wind farm in Rajasthan. Deliveries start late this year. And those turbines will be built at GE Vernova’s factory in Pune … which can turn out fifteen hundred megawatts a year. India is pushing for five hundred gigawatts of renewable energy.
Meanwhile … up in Denmark … a Danish wind tower maker named Welcon is raising its voice. Swedish utility Vattenfall just won two offshore wind tenders in Denmark. But when asked whether they would use European-made turbines … Vattenfall would not say.
Welcon’s chief executive Jens Risvig Pedersen said … and I quote …
“It would be completely absurd not to buy European products for the two new Danish offshore wind farms. That would simply shut down the European industry.”
The Danish trade union Dansk Metal agreed. Chinese turbines … they said … should not be financed with Danish taxpayer money. Vattenfall says it has not decided yet. But the debate is on.
And finally … a milestone that happened so quietly … nobody noticed. The world just crossed three terawatts of installed solar power. It took ten years to build the first terawatt. Less than three years for the second. And not even two more years for the third. Seventy-four countries now have at least one gigawatt of solar installed. That is up from forty-two in twenty-twenty. BloombergNEF expects nine terawatts by twenty thirty-six.
But here is the catch. Without batteries … solar hits a ceiling. Places like Australia and California already have so much solar that electricity prices go negative during the day. You heard that right. They pay people to use power. The answer is battery storage. But batteries are not able to keep up with the pace of solar.
Now … if you step back from all of this … something interesting emerges. Nobody in these stories is arguing about whether wind works. Not the judge in Oregon. Not RWE. Not even the Pentagon. The debate has moved on. The question is no longer … can you build a wind farm. The question is … who gets to decide where one goes.
Think about that. A federal judge did not rule that wind turbines are safe or good or necessary. She ruled that the government cannot ignore its own laws. The science was not on trial. The process was.
RWE did not surrender its leases because offshore wind failed. It surrendered them because one government made permitting impossible … while eighteen other wind farms in its global portfolio kept spinning.
And TotalEnergies did not buy four gigawatts of European renewables out of charity. It bought them because Shell … an oil company … decided those assets no longer fit its strategy. One oil major’s exit is another’s entrance. The assets did not lose value. They changed hands.
That is the story underneath all these headlines. Wind energy has crossed a threshold that most industries never reach. It is no longer competing on technology. It is competing on governance. The turbines work. The economics work. The engineering works. What varies … country by country … is whether the rules of the road are clear enough for capital to show up.
And capital … as we saw this week … will always find the door that is open.
That is the state of the wind industry for the 10th of August … twenty twenty-six. Join us for the Uptime Wind Energy podcast tomorrow.
