Les énergies renouvelables représentent 23% de la production d’électricité américaine

 

Aux États-Unis, la production d’électricité est en pleine mutation. En 2023, les énergies renouvelables ont répondu à 23% de la demande d’électricité, une avancée notable par rapport aux années précédentes. Cette progression est principalement due à l’augmentation de la capacité de production éolienne et solaire, qui, ensemble, ont commencé à éroder la part du charbon, désormais tombée sous les 16%. Parallèlement, la production d’électricité à partir de gaz naturel a atteint un niveau record, couvrant 43% du mix énergétique, selon BloombergNEF. La production d’électricité américaine d’origine nucléaire quant à elle s’approche des 17% .

Il faut dire que depuis la promulgation de l’Inflation Reduction Act (IRA) par Joe Biden en 2022, le gouvernement fait tout pour accélérer la transition énergétique du pays et prévoit d’y investir plus de 300 milliards de dollars dans les dix prochaines années.

 

 

Le modèle français : un mix énergétique prédominé par le nucléaire

 

Le modèle de transition énergétique français est bien distinct de celui de la plupart des pays, des États-Unis par exemple ou de l’Allemagne, jusqu’alors fortement dépendants du charbon. L’avantage de la France est d’avoir massivement investi dans le nucléaire civil dès les années 70. Malgré une période de recul du nucléaire, qui avait été fortement induit par certains lobbies, de l’éolien en particulier (on se rappellera notamment de Dominique Voynet, fervente anti-nucléaire qui s’était vantée d’avoir torpillé le nucléaire français), la France a repris le cap de l’énergie atomique. C’est d’ailleurs cette stratégie qui lui a permis de battre de nouveaux records d’exportation d’électricité en décembre 2023 et d’être le premier pays producteur d’électricité en Europe.

Le modèle français est donc bien différent de celui des États-Unis : il repose à près de 70% sur l’énergie nucléaire et à 14% sur l’hydroélectricité permise grâce à ses massifs montagneux notamment, le reste étant d’origine éolienne ou solaire. Le charbon quant à lui ne représentait plus que 0,17% de la production d’électricité en France en 2023. La France ne rejette par conséquent pas les énergies renouvelables. Elle mise sur un mix énergétique prédominé par l’énergie d’origine nucléaire, et c’est justement ce qui lui permet de se distinguer de la plupart des pays. Pour donner un ordre de grandeur, la production d’électricité français émet 10 fois moins que celle de l’Allemagne et huit fois moins que celle de l’Italie.

Americans filing their taxes could face privacy threats, reports the Washington Post: "We just need your OK on a couple of things," TurboTax says as you prepare your tax return. Alarm bells should be ringing in your head at the innocuous tone. This is where America's most popular tax-prep website asks you to sign away the ironclad privacy protections of your tax return, including the details of your income, home mortgage and student loan payments. With your permission to blab your money secrets, the company earns extra income from showing you advertisements for the next three years for things like credit cards and mortgage offers targeted to your financial situation. You have the legal right to say no when TurboTax asks for your permission to "share your data" or use your tax information to "improve your experience...." The article complains that granting permission allows TurboTax to share details with "sibling" companies "such as your salary, the amount of your tax refund, whether you received a tax break for student loans and the day you printed your tax return..." "You'll see that permission request once near the beginning of the tax prep process. If you skip it then, you'll see the same screen again near the end. You'll have to say yes or no..." This is part of the corporate arms race for your personal data. Everyone including the grocery store, your apps and the manufacturer of your car are gobbling information to profit from details of your life. With TurboTax, though, you have the power to refuse to participate... TurboTax and the online tax prep service from H&R Block have been asking every year to blab your tax return. We've cautioned you about it for each of the past two tax filing seasons. (I focused only on TurboTax this year.)

JetBlue Airways and Spirit Airlines announced on Monday that they would walk away from their planned $3.8 billion merger after federal antitrust regulators successfully challenged the deal in court. JetBlue said it would pay Spirit $69 million to exit the deal. From a report: A federal judge in Boston blocked the proposed merger on Jan. 16, siding with the Justice Department in determining that the merger would reduce competition in the industry and give airlines more leeway to raise ticket prices. The judge, William G. Young of the U.S. District Court for the District of Massachusetts, noted that Spirit played a vital role in the market as a low-cost carrier and that travelers would have fewer options if JetBlue absorbed it. "We are proud of the work we did with Spirit to lay out a vision to challenge the status quo, but given the hurdles to closing that remain, we decided together that both airlines' interests are better served by moving forward independently," JetBlue's chief executive, Joanna Geraghty, said in a statement on Monday. "We wish the very best going forward to the entire Spirit team." JetBlue and Spirit appealed Judge Young's decision. JetBlue filed an appellate brief last week arguing that the deal should be allowed to go through. But in a regulatory filing on Jan. 26, JetBlue said it might terminate the deal. Spirit said in its own filing the same day that it believed "there is no basis for terminating" the agreement.

The U.S. government announced Tuesday sanctions against the founder of the notorious spyware company Intellexa and one of his business partners. From a report: This is the first time the U.S. government has targeted specific people, in addition to companies, with sanctions related to the misuse of commercial spyware. And it signifies an escalation of the White House and U.S. government's efforts to curb the spyware industry. "Today's actions represent a tangible step forward in discouraging the misuse of commercial surveillance tools, which increasingly present a security risk to the United States and our citizens," said Brian E. Nelson, U.S Treasury's under secretary for terrorism and financial intelligence, was quoted as saying in a press release. "The United States remains focused on establishing clear guardrails for the responsible development and use of these technologies while also ensuring the protection of human rights and civil liberties of individuals around the world." The U.S. Treasury imposed sanctions on Tal Dilian, the founder of Intellexa and a veteran of the spyware industry; and Sara Aleksandra Fayssal Hamou, who is not as well-known as Dilian. Hamou, according to the Treasury, has a leadership role in Intellexa, is an expert in off-shoring, and provided the company managerial services, such as renting office space in Greece.

A new report warns that a boom in computer chip manufacturing in the US could fuel demand for dirty energy, despite companies' environmental claims. The solution for manufacturers, surprisingly, might be to act more like other big tech companies chasing climate goals. From a report: New semiconductor factories being built in the US by four of the biggest manufacturers -- Intel, TSMC, Samsung, and Micron -- could use more than twice as much electricity as the city of Seattle once they're operational. These companies claim to run on renewable energy, but according to an analysis by nonprofit Stand.earth, that's not entirely true. Semiconductors happen to make up a big chunk of a device's carbon footprint. And unless companies turn to clean energy, they could wind up driving up greenhouse gas emissions as domestic chip manufacturing makes a comeback. The CHIPS and Science Act, which passed in 2022, set aside $52.7 billion in funding for domestic chip manufacturing. Now, the four companies scrutinized in the report have plans to build megafactories in Arizona, Ohio, Oregon, Idaho, Texas, and New York. Each of those megafactories alone could use as much electricity as a medium-sized town, according to the report. Cumulatively, nine facilities could eventually add 2.1 gigawatts in new electricity demand. "We're not slowing down on any of our sustainability commitments, even with our recently announced investments," Intel said in an email.

The U.S. Securities and Exchange Commission on Wednesday approved a rule that will require some public companies to report their greenhouse gas emissions and climate risks, after last-minute revisions that weakened the directive in the face of strong pushback from companies. From a report: The rule was one of the most anticipated in recent years from the nation's top financial regulator, drawing more than 24,000 comments from companies, auditors, legislators and trade groups over a two-year process. It brings the U.S. closer to the European Union and California, which moved ahead earlier with corporate climate disclosure rules. The SEC rule passed 3-2, with three Democratic commissioners supporting it and two Republicans opposed. Since the SEC proposed a rule two years ago, experts had said it was likely to face litigation almost immediately. SEC Chairman Gary Gensler, one of the Democrats, acknowledged that was a factor the agency considered as it worked toward a final rule. "We've seriously considered what people have said about our legal authorities," Gensler said on Wednesday.

An anonymous reader shares a report: In the 1960s, secret test flights of advanced government spy planes generated U.F.O. sightings. More recently, government and commercial drones, new kinds of satellites and errant weather balloons have led to a renaissance in unusual observations. But, according to a new report, none of these sightings were of alien spacecraft. The new congressionally mandated Pentagon report found no evidence that the government was covering up knowledge of extraterrestrial technology and said there was no evidence that any U.F.O. sightings represented alien visitation to Earth. The 63-page document is the most sweeping rebuttal the Pentagon has issued in recent years to counter claims that it has information on extraterrestrial visits or technology. But amid widespread distrust of the government, the report is unlikely to calm a growing obsession with aliens. Maj. Gen. Patrick Ryder, a Defense Department spokesman, said the Pentagon approached the report with an open mind and no preconceived notions, but simply found no evidence to back up claims of secret programs, hidden alien technology or anything else extraterrestrial. The new report suggests that the public's belief that the government is hiding what it knows will probably continue. The report adds: Nevertheless the public is unlikely to be swayed. Many people dismiss the government's claims that nothing interesting is going on in Pentagon videos that appear to show strange objects, citing accounts by Navy pilots that they observed objects whose movements cannot be easily explained. The new report notes that in the past, particularly in the 1950s, there was interest in U.F.O.s, but today the attention on unexplained sightings is greater than ever before. Politico adds: The Pentagon has disclosed that the government once considered a program to recover and reverse-engineer any captured alien spacecraft, an effort that never came to fruition but fueled conspiracy theories about a cover-up.

Roughly $138 billion in U.S. student loan debt has now been cancelled, reports CNN. "That's about one-third of the $430 billion that would've been canceled under the president's one-time forgiveness plan, which was struck down by the Supreme Court last year." It's 9% of all outstanding federal student loan debt, according to the article, "wiping out debts for about 3.9 million borrowers — by using a number of existing programs that aim to offer debt relief for certain groups of struggling borrowers..." What President Biden has been doing — before and after the Supreme Court ruling — is using existing student loan forgiveness programs to deliver relief to certain groups of borrowers, like public-sector workers (through the Public Service Loan Forgiveness program) and borrowers who were defrauded by their college (through the borrower defense to repayment program). His administration also made discharges for borrowers who are totally and permanently disabled. None of these programs expire, meaning they will help qualifying borrowers now and in the future. In some cases, Biden's administration has expanded the reach of these programs, making more borrowers eligible. And in other cases, it has made an effort to correct past administrative errors made to borrowers' student loan accounts by conducting a one-time recount of borrowers' past payments. This effort helps make sure people receive the loan forgiveness they may already qualify for by having made at least 20 years of payments in an income-driven plan, which calculates monthly payment amounts based on a borrower's income and family size, rather than the amount owed. The recount is expected to be completed by July... Last year, the administration created a new income-driven repayment plan. Known as SAVE, the new plan offers the most generous terms for low-income borrowers. Those who originally borrowed $12,000 or less will see their remaining debt canceled after making payments for at least 10 years... [The administration] is working on implementing another path toward a broad student loan forgiveness program, this time relying on a different legal authority in hopes that this attempt holds up in court. This proposal is currently making its way through a lengthy rulemaking process and has yet to be finalized.

Slashdot reader ArchieBunker shared this article from NBC News: Exposure to leaded gasoline lowered the IQ of about half the population of the United States, a new study estimates. The peer-reviewed study, published Monday in the journal Proceedings of the National Academy of Sciences, focuses on people born before 1996 — the year the U.S. banned gas containing lead. Overall, the researchers from Florida State University and Duke University found, childhood lead exposure cost America an estimated 824 million points, or 2.6 points per person on average. Certain cohorts were more affected than others. For people born in the 1960s and the 1970s, when leaded gas consumption was skyrocketing, the IQ loss was estimated to be up to 6 points and for some, more than 7 points. Exposure to it came primarily from inhaling auto exhaust. "Lead is a neurotoxin, and no amount of it is safe.

The US could further tighten controls on China's access to sophisticated semiconductor technologies, Commerce Secretary Gina Raimondo said, signaling Washington may intensify its campaign to prevent Beijing catching up in military capabilities. From a report: "We cannot allow China to have access for their military advancement to our most sophisticated technology," she told reporters in Manila on Monday. "So yes, we will do whatever it takes to protect our people including expanding our controls." Raimondo, who is leading a trade delegation to the Philippines and Thailand, was asked if the US is planning to add new restrictions on the sale of semiconductors to China. The Biden administration is mulling fresh sanctions on several Chinese tech companies, including memory chipmaker ChangXin Memory Technologies Inc., while pushing allies to do more to curb the export of advanced tech to China, Bloomberg has reported in recent days. Washington has taken aim at China's chip industry for years, imposing sweeping controls on the export of advanced semiconductor-making machines and sophisticated chips like those used to develop artificial intelligence. Japan and the Netherlands, the two key countries where chip-making equipment is developed, joined the US effort last year.

After weeks of testing, an electronic system for filing returns directly to the IRS is now available for taxpayers from 12 selected states. From a report: The new system, called Direct File, is a free online tool. Taxpayers in the selected states who have very simple W-2s and claim a standard deduction may be eligible to use it this tax season to file their federal income taxes. The program will also offer a Spanish version, which will be available starting at 1 p.m. Eastern Time on Tuesday. The Treasury Department estimates that one-third of all federal income tax returns filed could be prepared using Direct File and that 19 million taxpayers may be eligible to use the tool this tax season. "Direct File will offer millions of Americans a free and simple way to file their taxes, with no expensive and unnecessary filing fees and no upselling, putting hundreds of dollars back in the pocket of working families each year, consistent with President Biden's pledge to lower costs," said National Economic Advisor Lael Brainard. Certain taxpayers in Florida, New Hampshire, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, Arizona, Massachusetts, California and New York can participate. Direct File can only be used to file federal income taxes, taxpayers from states that require filing state taxes will need to do so separately.

A six-week audit by the Federal Aviation Administration of Boeing's production of the 737 Max jet found dozens of problems (non-paywalled link) throughout the manufacturing process at the plane maker and one of its key suppliers, according to a slide presentation reviewed by The New York Times. From the report: The air-safety regulator initiated the examination after a door panel blew off a 737 Max 9 during an Alaska Airlines flight in early January. Last week, the agency announced that the audit had found "multiple instances" in which Boeing and the supplier, Spirit AeroSystems, failed to comply with quality-control requirements, though it did not provide specifics about the findings. The presentation reviewed by The Times, though highly technical, offers a more detailed picture of what the audit turned up. Since the Alaska Airlines episode, Boeing has come under intense scrutiny over its quality-control practices, and the findings add to the body of evidence about manufacturing lapses at the company. For the portion of the examination focused on Boeing, the F.A.A. conducted 89 product audits, a type of review that looks at aspects of the production process. The plane maker passed 56 of the audits and failed 33 of them, with a total of 97 instances of alleged noncompliance, according to the presentation. The F.A.A. also conducted 13 product audits for the part of the inquiry that focused on Spirit AeroSystems, which makes the fuselage, or body, of the 737 Max. Six of those audits resulted in passing grades, and seven resulted in failing ones, the presentation said. At one point during the examination, the air-safety agency observed mechanics at Spirit using a hotel key card to check a door seal, according to a document that describes some of the findings. That action was "not identified/documented/called-out in the production order," the document said.

The head of the National Transportation Safety Board (NTSB) says investigators still do not know who worked on a Boeing 737 MAX 9 door plug involved in a Jan. 5 Alaska Airlines midair emergency and that video footage was overwritten. From a report: NTSB Chair Jennifer Homendy said in a letter to senators that investigators sought security camera footage when the door plug was opened and closed in September but were informed the material was overwritten. "The absence of those records will complicate the NTSB's investigation moving forward," Homendy said. "To date, we still do not know who performed the work to open, reinstall, and close the door plug on the accident aircraft." The NTSB said previously four key bolts were missing from the door plug that blew out on the plane. Last week, Homendy said she spoke to Boeing CEO David Calhoun "and asked for the names of the people who performed the work. He stated he was unable to provide that information and maintained that Boeing has no records of the work being performed." Boeing said it "will continue supporting this investigation in the transparent and proactive fashion we have supported all regulatory inquiries into this accident. We have worked hard to honor the rules about the release of investigative information." A Boeing official, speaking on condition of anonymity, told Reuters the planemaker standard practice is to overwrite security videos after 30 days.

The Federal Trade Commission (FTC) filed a legal complaint against two companies based in Cyprus on Wednesday that it claims are behind a wave of malicious pop-ups that trick people into downloading a fake piece of antivirus software that generated tens of millions of dollars for its operators, according to court records. From a report: The scam also involved misrepresenting results on malware repository VirusTotal as infections on the user's own computer. (Update: after the publication of this piece the FTC announced that Restoro and Reimage will pay $26 million to settle the FTC's charges.) The move is the latest from the FTC in a series of actions in the privacy and cybersecurity space. In January, the FTC banned a data broker called X-Mode from selling sensitive location data after I revealed it was harvesting location data from Muslim prayer and dating apps. In this case, the FTC says it went "undercover" against the two related companies, called Restoro and Reimage, to buy the deceiving software and have phone calls with company representatives. "Since at least January 2018, Defendants have operated a tech support scheme that has bilked tens of millions of dollars from consumers, particularly older consumers," the FTC's complaint reads. The complaint is seeking a permanent injunction against the two companies as well as monetary relief.

U.S. Supreme Court justices on Monday appeared skeptical of a challenge on free speech grounds to how President Joe Biden's administration encouraged social media platforms to remove posts that federal officials deemed misinformation, including about elections and COVID-19. From a report: The justices heard oral arguments in the administration's appeal of a lower court's preliminary injunction constraining how White House and certain other federal officials communicate with social media platforms. The Republican-led states of Missouri and Louisiana, along with five individual social media users, sued the administration. They argued that the government's actions violated the U.S. Constitution's First Amendment free speech rights of users whose posts were removed from platforms such as Facebook, YouTube, and Twitter, now called X. The case tests whether the administration crossed the line from mere communication and persuasion to strong arming or coercing platforms - sometimes called "jawboning" - to unlawfully censor disfavored speech, as lower courts found.

The Justice Department is poised to sue Apple as soon as Thursday, accusing the world's second most valuable tech company of violating antitrust laws by blocking rivals from accessing hardware and software features of its iPhone. From a report: The suit, which is expected to be filed in federal court, according to people familiar with the matter, escalates the Biden administration's antitrust fights against most of the biggest US technology giants. The Justice Department is already suing Alphabet's Google for monopolization, while the Federal Trade Commission is pursuing antitrust cases against Meta and Amazon. The coming case will mark the third time that the Justice Department has sued Apple for antitrust violations in the past 14 years, but it is the first case accusing the iPhone maker of illegally maintaining its dominant position.

The Justice Department sued Apple on Thursday, alleging the tech giant blocked software developers and mobile gaming companies from offering better options on the iPhone, resulting in higher prices for consumers. WSJ: The government's antitrust complaint, filed in a New Jersey federal court, alleges Apple used its control of the iPhone to prevent competitors from offering innovative services such as digital wallets and limited the functionality of hardware products that compete with Apple's own devices. The suit also claims that Apple makes it difficult for users to switch to devices that don't use Apple's operating system, such as Android smartphones. "Consumers should not have to pay higher prices because companies violate the antitrust laws," Attorney General Merrick Garland said in a statement. Apple said it plans to vigorously defend against the lawsuit. "This lawsuit threatens who we are and the principles that set Apple products apart in fiercely competitive markets," an Apple spokesman said in a statement. "If successful, it would hinder our ability to create the kind of technology people expect from Apple -- where hardware, software, and services intersect." The case against Apple is the last shoe to drop on the big four tech giants by U.S. antitrust officials.

An anonymous reader shares a report: On Monday, the Biden administration announced that six new countries had joined an international coalition to fight the proliferation of commercial spyware, sold by companies such as NSO Group or Intellexa. Now, some investors have announced that they too are committed to fighting spyware. But at least one of those investors, Paladin Capital Group, has previously invested in a company that developed malware, according to a leaked 2021-dated slide deck obtained by TechCrunch, although the firm tells TechCrunch it "got out" of the firm some time ago. In the last couple of years, the U.S. government has led an effort to limit or at least restrain the use of spyware across the world by putting surveillance tech makers like NSO Group, Candiru, and Intellexa on blocklists, as well as imposing export controls on those companies and visa restrictions on people involved in the industry. More recently, the government has imposed economic sanctions not only on companies, but also directly on the executive who founded Intellexa. These actions have put others in the spyware industry on alert. In a call with reporters on Monday that TechCrunch attended, a senior Biden administration official said that a representative from Paladin participated in meetings at the White House on March 7, as well as this week in Seoul, where governments gathered for the Summit for Democracy to discuss spyware. Paladin, one of the biggest investors in cybersecurity startups, and several other venture firms published a set of voluntary investment principles, noting that they would invest in companies that "enhance the defense, national security, and foreign policy interests of free and open societies." "For us, it was an important first step in having an investor outline both recognition that investments should not be going towards companies that are undertaking selling products, and selling to clients that can undermine free and fair societies," the senior administration official said in the call, where journalists agreed not to quote the officials by name.

The U.S. Department of Transportation has announced it will conduct a review of the data practices of the country's ten largest airlines, amid concerns over potential misuse of customer information for upselling, overcharging, targeted advertising, and third-party data sales, as well as the security of systems handling sensitive data such as passport numbers. From a report: The probe will look at air carriers' policies and procedures to determine if they are safeguarding personal info properly, unfairly or deceptively monetizing it, or sharing it with third parties, the agency said yesterday. If they're indeed doing anything "problematic," they can look forward to scrutiny, fines, and new rules, says the DOT. "Airline passengers should have confidence that their personal information is not being shared improperly with third parties or mishandled by employees," said US Transportation Secretary Pete Buttigieg. "This review of airline practices is the beginning of a new initiative by DOT to ensure airlines are being good stewards of sensitive passenger data." The ten airlines going under the magnifying glass are Delta, United, American, Southwest, Alaska, JetBlue, Spirit, Frontier, Hawaiian and Allegiant.
