Thank you, Thomas Edison, for inventing the lightbulb. We all benefit every day from this source. Despite the importance of lightbulbs, consumers need more information.

The two most common types are incandescent and fluorescent. Incandescent bulbs glow when electric current passes through a filament. All lamps with a filament are considered incandescent even when they are modified with gasses such as halogen, krypton and xenon.

Fluorescent bulbs produce light when an electric arc passes between cathodes and excites mercury and other gases, producing radiant energy. Phosphor coatings convert energy into visible light. The compact fluorescent has been promoted as energy-saving, low heat and long-lasting. The ballast for the CFL is below the lamp and above the threaded base, increasing heat, which shortens the lamp life. Remember that fluorescent bulbs cannot start in cold weather.

All fluorescent lamps contain mercury and need to be thoughtfully discarded. If they break, open the windows and pick up the residue with tape. Do not contaminate your vacuum cleaner!

Fluorescent lighting color is described by the Kelvin rating. This is based on our perception of how cool or warm the light appears.

Use 2700 kelvins, or warm white, in homes, counseling offices and restaurants.

Use 3000 kelvins, or soft white, a peachy source almost like incandescent, in home furnishing stores and waiting rooms.

Use 3500 kelvins in the midlevel of warm to cool in commercial, retail stores and offices. This color temperature is terrific, especially when used with a silver parabolic lens that brightens the flatness of fluorescent light.

Use 4100 kelvins, or cool white, only if you want the feeling of an ice palace. This is the color temperature that is duplicated on an overcast day in the winter.

Use 5000 kelvins in hospitals, laboratories and doctors offices where a crisp light is needed.

Use 6500 kelvins, the bluest, in jewelry and accessory stores.

Torcheres and task lighting use halogen bulbs that provide high contrast, a brilliant color that duplicates sunlight. They provide more light than a typical incandescent. To preserve their longer life, protect the quartz casing from the skin oil on your hands, which will change the tension and cause a shorter lamp life. During installation, use a glove or a thin foam pad.

The tungsten redeposits onto the filament and is considered a self-cleaning bulb when the bulb is burned at full power. If the bulb is dimmed often, operate at full power occasionally to extend lamp life.

Halogen bulbs usually cost more but give more light per watt of energy used, last longer and enhance color. They are a bargain. But I do not use halogen reflectors in walkways they seem like interrogation lights and cast shadows on your face. Halogen bulbs are wonderful over work surfaces, coffee tables, dining tables and to directionally light artwork.

Xenon gas lamps burn cooler than halogen but the light they produce tends to be blue. The blue-tinted auto headlights you see at night are xenon. They have an average lamp life of 2,000 hours like halogen.

The nuclear power dispute driving a wedge between France and Germany

Franco-German Nuclear Power Divide shapes EU energy policy, electricity market reform, and decarbonization strategies, as Paris backs reactors and state subsidies while Berlin prioritizes renewables, hydrogen, and energy security after Russian gas shocks.

 

Key Points

A policy rift over nuclear shaping EU market reform, subsidies, and the balance between reactors and renewables.

✅ Nuclear in EU targets vs. renewables-first strategy

✅ Market design disputes over long-term power prices

✅ Energy security after Russian gas; hydrogen definitions

 

Near the French village of Fessenheim, facing Germany across the Rhine, a nuclear power station stands dormant. The German protesters that once demanded the site’s closure have decamped, in a sign of Europe's nuclear decline, and the last watts were produced three years ago. 

But disagreements over how the plant from 1977 should be repurposed persist, speaking to a much deeper divide over nuclear power, which Eon chief's warning to Germany underscored, between the two countries on either side of the river’s banks.

German officials have disputed a proposal to turn it into a centre to treat metals exposed to low levels of radioactivity, Fessenheim’s mayor Claude Brender says. “They are not on board with anything that might in some way make the nuclear industry more acceptable,” he adds.

France and Germany’s split over nuclear power is a tale of diverging mindsets fashioned over decades, including since the Chernobyl disaster in USSR-era Ukraine. But it has now become a major faultline in a touchy relationship between Europe’s two biggest economies.

Their stand-off over how to treat nuclear in a series of EU reforms has consequences for how Europe plans to advance towards cleaner energy. It will also affect how the bloc secures power supplies as the region weans itself off Russian gas, even though nuclear would do little for the gas issue, and how it provides its industry with affordable energy to compete with the US and China. 

“There can be squabbles between partners. But we’re not in a retirement home today squabbling over trivial matters. Europe is in a serious situation,” says Eric-André Martin, a specialist in Franco-German relations at French think-tank IFRI. 

France, which produces two-thirds of its power from nuclear plants and has plans for more reactors, is fighting for the low-carbon technology to be factored into its targets for reducing emissions and for leeway to use state subsidies to fund the sector.

For Germany, which closed its last nuclear plants this year and, having turned its back on nuclear, has been particularly shaken by its former reliance on Russian gas, there’s concern that a nuclear drive will detract from renewable energy advances.

But there is also an economic subtext in a region still reeling from an energy crisis last year, reviving arguments for a needed nuclear option for climate in Germany, when prices spiked and laid bare how vulnerable households and manufacturers could become.

Berlin is wary that Paris would benefit more than its neighbours if it ends up being able to guarantee low power prices from its large nuclear output as a result of new EU rules on electricity markets, amid talk of a possible U-turn on the phaseout, people close to talks between the two countries say.

Ministers on both sides have acknowledged there is a problem. “The conflict is painful. It’s painful for the two governments as well as for our [EU] partners,” Sven Giegold, state secretary at the German economy and climate action ministry, where debates about whether a nuclear resurgence is possible persist, tells the Financial Times. 

Agnès Pannier-Runacher, France’s energy minister, says she wants to “get out of the realm of the emotional and move past the considerable misunderstandings that have accumulated in this discussion”.

In a joint appearance in Hamburg last week, German chancellor Olaf Scholz and French president Emmanuel Macron made encouraging noises over their ability to break the latest deadlock: a disagreement over the design of the EU’s electricity market. Ministers had been due to agree a plan in June but will now meet on October 17 to discuss the reform, aimed at stabilising long-term prices.

But the French and German impasse on nuclear has already slowed down debates on key EU policies such as rules on renewable energy and how hydrogen should be produced. Smaller member states are becoming impatient. The delay on the market design is “a big Franco-German show of incompetence again”, says an energy ministry official from another EU country who requested anonymity.

3 Reasons Why Cheap Abundant Electricity Is Getting Closer To Reality

Renewable Energy Breakthroughs drive quantum dots solar efficiency, Air-gen protein nanowires harvesting humidity, and cellulose membranes for flow batteries, enabling printable photovoltaics, 24/7 clean power, and low-cost grid storage at commercial scale.

 

Key Points

Advances like quantum dot solar, Air-gen, and cellulose flow battery membranes that improve clean power and storage.

✅ Quantum dots raise solar conversion efficiency, are printable

✅ Air-gen harvests electricity from humidity with protein nanowires

✅ Cellulose membranes cut flow battery costs, aid grid storage

 

Science never sleeps. The quest to find new and better ways to do things continues in thousands of laboratories around the world. Today, the global economy is based on the use of electricity, and one analysis shows wind and solar potential could meet 80% of US demand, underscoring what is possible. If there was a way to harness all the energy from the sun that falls on the Earth every day, there would be enough of electricity available to meet the needs of every man, woman, and child on the planet with plenty left over. That day is getting closer all the time. Here are three reasons why.

Quantum Dots Make Better Solar Panels
According to Science Daily, researchers at the University of Queensland have set a new world record for the conversion of solar energy to electricity using quantum dots — which pass electrons between one another and generate electrical current when exposed to solar energy in a solar cell device. The solar devices they developed have beaten the existing solar conversion record by 25%.

“Conventional solar technologies use rigid, expensive materials. The new class of quantum dots the university has developed are flexible and printable,” says professor Lianzhou Wang, who leads the research team. “This opens up a huge range of potential applications, including the possibility to use it as a transparent skin to power cars, planes, homes and wearable technology. Eventually it could play a major part in meeting the United Nations’ goal to increase the share of renewable energy in the global energy mix.”

“This new generation of quantum dots is compatible with more affordable and large-scale printable technologies,” he adds. “The near 25% improvement in efficiency we have achieved over the previous world record is important. It is effectively the difference between quantum dot solar cell technology being an exciting prospect and being commercially viable.” The research was published on January 20 in the journal Nature Energy.

Electricity From Thin Air
Science Daily also reports that researchers at UMass Amherst also have interesting news. They claim they created a device called an Air-gen, short for air powered generator. (Note: recently we reported on other research that makes electricity from rainwater.) The device uses protein nanowires created by a microbe called Geobacter. Those nanowires can generate electricity from thin air by tapping the water vapor present naturally in the atmosphere. “We are literally making electricity out of thin air. The Air-gen generates clean energy 24/7. It’s the most amazing and exciting application of protein nanowires yet,” researchers Jun Yao and Derek Lovely say. There work was published February 17 in the journal Nature.

The new technology developed in Yao’s lab is non-polluting, renewable, and low-cost. It can generate power even in areas with extremely low humidity such as the Sahara Desert. It has significant advantages over other forms of renewable energy including solar and wind, Lovley says, because unlike these other renewable energy sources, the Air-gen does not require sunlight or wind, and “it even works indoors,” a point underscored by ongoing grid challenges that slow full renewable adoption.

Yao says, “The ultimate goal is to make large-scale systems. For example, the technology might be incorporated into wall paint that could help power your home. Or, we may develop stand-alone air-powered generators that supply electricity off the grid, and in parallel others are advancing bio-inspired fuel cells that could complement such devices. Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production. This is just the beginning of a new era of protein based electronic devices.”

Improved Membranes For Flow Batteries From Cellulose
Storing energy is almost as important to decarbonizing the environment as making it in the first place, with the rise of affordable solar batteries improving integration.  There are dozens if not hundreds of ways to store electricity and they all work to one degree or another. The difference between which ones are commercially viable and ones that are not often comes down to money.

Flow batteries — one approach among many, including fuel cells for renewable storage — use two liquid electrolytes — one positively charged and one negatively charged — separated by a membrane that allows electrons to pass back and forth between them. The problem is, the liquids are highly corrosive. The membranes used today are expensive — more than $1,300 per square meter.

Phys.org reports that Hongli Zhu, an assistant professor of mechanical and industrial engineering at Northeastern University, has successfully created a membrane for use in flow batteries that is made from cellulose and costs just $147.68 per square meter. Reducing the cost of something by 90% is the kind of news that gets people knocking on your door.

The membrane uses nanocrystals derived from cellulose in combination with a polymer known as polyvinylidene fluoride-hexafluoropropylene.  The naturally derived membrane is especially efficient because its cellular structure contains thousands of hydroxyl groups, which involve bonds of hydrogen and oxygen that make it easy for water to be transported in plants and trees.

In flow batteries, that molecular makeup speeds the transport of protons as they flow through the membrane. “For these materials, one of the challenges is that it is difficult to find a polymer that is proton conductive and that is also a material that is very stable in the flowing acid,” Zhu says.

Cellulose can be extracted from natural sources including algae, solid waste, and bacteria. “A lot of material in nature is a composite, and if we disintegrate its components, we can use it to extract cellulose,” Zhu says. “Like waste from our yard, and a lot of solid waste that we don’t always know what to do with.”

Flow batteries can store large amounts of electricity over long periods of time — provided the membrane between the storage tanks doesn’t break down. To store more electricity, simply make the tanks larger, which makes them ideal for grid storage applications where there is often plenty of room to install them. Slashing the cost of the membrane will make them much more attractive to renewable energy developers and help move the clean energy revolution forward.

The Takeaway
The fossil fuel crazies won’t give up easily. They have too much to lose and couldn’t care less if life on Earth ceases to exist for a few million years, just so long as they get to profit from their investments. But they are experiencing a death of a thousand cuts. None of the breakthroughs discussed above will end thermal power generation all by itself, but all of them, together with hundreds more just like them happening every day, every week, and every month, even as we confront clean energy's hidden costs across supply chains, are slowly writing the epitaph for fossil fuels.

And here’s a further note. A person of Chinese ancestry is the leader of all three research efforts reported on above. These are precisely the people being targeted by the United States government at the moment as it ratchets up its war on immigrants and anybody who cannot trace their ancestry to northern Europe. Imagine for a moment what will happen to America when researchers like them depart for countries where they are welcome instead of despised.

Nevada on track to reach RPS mandate of 50% renewable electricity by 2030: report

Nevada Renewable Portfolio Standard 2030 targets 50% clean energy, advancing solar, geothermal, and wind, cutting GHG emissions, phasing out coal, and expanding storage, EV infrastructure, and in-state renewables under PUCN oversight and tax abatements.

 

Key Points

A state mandate requiring 50% of electricity from renewables by 2030, driving solar, geothermal, wind, and storage.

✅ 50% clean power by 2030; 100% carbon-free target by 2050

✅ Growth in solar, geothermal, wind; coal phase-out; natural gas remains

✅ RETA incentives spur 6.1 GW capacity, jobs, and in-state investment

 

Nevada is on track to meet its Renewable Portfolio Standard of 50% of electricity generated by renewable energy sources by 2030, according to the Governor's Office of Energy's annual Status of Energy Report.

Based on compliance reports the Public Utilities Commission of Nevada has received, across all providers, about 20% of power is currently generated by renewable resources, and, nationally, renewables ranked second in 2020 as filings show Nevada's investor-owned utility and other power providers have plans to reach the state's ambitious RPS of 50% by 2030, according to the report released Jan. 28.

"Because transportation and electricity generation are Nevada's two largest contributors to greenhouse gas emissions, GOE's program work in 2021 underscored our focus on transportation electrification and reaching the state's legislatively required renewable portfolio standard," GOE Director David Bobzien said in a statement Jan. 28. "While electricity generated from renewable resources currently accounts for about 25% of the state's electricity, a share similar to projections that renewables will soon provide about one-fourth of U.S. electricity overall, we continue to collaborate with the Public Utilities Commission of Nevada, electricity providers, the renewable energy industry and conservation organizations to ensure Nevada reaches our target of 50% clean energy by 2030."

The state's RPS, enacted in 1997 and last modified in 2019, requires an increase in renewable energy, starting with 22% in 2020 and increasing to 50% by 2030. The increase in renewables will reduce GHG emissions and help the state reach its goal of 100% carbon-free power by 2050, while states like Rhode Island have a 100% by 2030 plan, highlighting varying timelines.

Renewable additions
The state added 1.332 GW of renewable capacity in 2021 as part of the Renewable Energy Tax Abatement program, at a time when U.S. renewable energy hit a record 28% in April, for a total renewable capacity of 6.117 GW, according to the report.

The RETA program awards partial sales and use tax and partial property-tax abatements to eligible renewable energy facilities, which increase Nevada's tax revenue and create jobs in a growing industry. Eligible projects must employ at least 50% Nevada workers, pay 175% of Nevada's average wage during construction, and offer health care benefits to workers and their dependents.

Since its adoption in 2010, the GOE has approved 60 projects, including large-scale solar PV, solar thermal, biomass, geothermal and wind projects throughout the state, according to the report. Projects granted abatements in 2021 include:

  • 100-MW Citadel Solar Project
  • 150-MW Dry Lake Solar + Storage Project
  • 714-MW Gemini Solar Project
  • 55-MW North Valley Power Geothermal Project
  • 113-MW Boulder Flats Solar Project
  • 200-MW Arrow Canyon Solar Project

"Nevada does not produce fossil fuels of any significant amount, and gasoline, jet fuel and natural gas for electricity or direct use must be imported," according to the report. "Transitioning to domestically produced renewable resources and electrified transportation can provide cost savings to Nevada residents and businesses, as seen in Idaho's largely renewable mix today, while reducing GHG emissions. About 86% of the fuel for energy that Nevada consumes comes from outside the state."

Phasing out coal plants
Currently, more than two-thirds of the state's electricity is produced by natural gas-fired power plants, with renewables covering most of the remaining generation, according to the report. Nevada continues to phase out its remaining coal power plants, as renewables surpassed coal nationwide in 2022, which provide less than 10% of produced electricity.

"Nevada has seen a significant increase in capturing its abundant renewable energy resources such as solar and geothermal," according to the report. "Renewable energy production continues to grow, powering Nevada homes and business and serves to diversify the state's economy by exporting solar and geothermal to neighboring states, as California neared 100% renewable electricity for the first time. Nevada has more than tripled its renewable energy production since 2011."

Green energy could drive Covid-19 recovery with $100tn boost

Renewable Energy Economic Recovery drives GDP gains, job growth, and climate targets by accelerating clean energy investment, green hydrogen, and grid modernization, delivering high ROI and a resilient, low-carbon transition through stimulus and policy alignment.

 

Key Points

A strategy to boost GDP and jobs by accelerating clean power and green hydrogen while meeting climate goals.

✅ Adds $98tn to global GDP by 2050; $3-$8 return per $1 invested

✅ Quadruples clean energy jobs to 42m; improves health and welfare

✅ Cuts CO2 70% by 2050; enables net-zero via green hydrogen

 

Renewable energy could power an economic recovery from Covid-19 through a green recovery that spurs global GDP gains of almost $100tn (£80tn) between now and 2050, according to a report.

The International Renewable Energy Agency’s new IRENA report found that accelerating investment in renewable energy could generate huge economic benefits while helping to tackle the global climate emergency.

The agency’s director general, Francesco La Camera, said the global crisis ignited by the coronavirus outbreak exposed “the deep vulnerabilities of the current system” and urged governments to invest in renewable energy to kickstart economic growth and help meet climate targets.

The agency’s landmark report found that accelerating investment in renewable energy would help tackle the climate crisis and would in effect pay for itself.

Investing in renewable energy would deliver global GDP gains of $98tn above a business-as-usual scenario by 2050, as clean energy investment significantly outpaces fossil fuels, by returning between $3 and $8 on every dollar invested.

It would also quadruple the number of jobs in the sector to 42m over the next 30 years, and measurably improve global health and welfare scores, according to the report.

“Governments are facing a difficult task of bringing the health emergency under control while introducing major stimulus and recovery measures, as a US power coalition demands action,” La Camera said. “By accelerating renewables and making the energy transition an integral part of the wider recovery, governments can achieve multiple economic and social objectives in the pursuit of a resilient future that leaves nobody behind.”

The report also found that renewable energy could curb the rise in global temperatures by helping to reduce the energy industry’s carbon dioxide emissions by 70% by 2050 by replacing fossil fuels, with measures like a fossil fuel lockdown hastening the shift.

Renewables could play a greater role in cutting carbon emissions from heavy industry and transport to reach virtually zero emissions by 2050, particularly by investing in green hydrogen.

The clean-burning fuel, which can replace the fossil fuel gas in steel and cement making, could be made by using vast amounts of clean electricity to split water into hydrogen and oxygen elements.

Andrew Steer, chief executive of the World Resources Institute, said: “As the world looks to recover from the current health and economic crises, we face a choice: we can pursue a modern, clean, healthy energy system, or we can go back to the old, polluting ways of doing business. We must choose the former.”

The call for a green economic recovery from the coronavirus crisis comes after a warning from Dr Fatih Birol, head of the International Energy Agency, that government policies must be put in place to avoid an investment hiatus in the energy transition, even as the solar and wind industry faces Covid-19 disruptions.

“We should not allow today’s crisis to compromise the clean energy transition, even as wind power growth persists despite Covid-19,” he said. “We have an important window of opportunity.”

Ignacio Galán, the chairman and CEO of the Spanish renewables giant Iberdrola, which owns Scottish Power, said the company would continue to invest billions in renewable energy as well as electricity networks and batteries to help integrate clean energy in the electricity.

“A green recovery is essential as we emerge from the Covid-19 crisis. The world will benefit economically, environmentally and socially by focusing on clean energy,” he said. “Aligning economic stimulus and policy packages with climate goals is crucial for a long-term viable and healthy economy.”

Hinkley C nuclear reactor roof lifted into place

Hinkley Point C dome lift marks a nuclear reactor milestone in Somerset, as EDF used Big Carl crane to place a 245-tonne steel roof, enabling 2027 startup amid costs, delays, and precision indoor welding.

 

Key Points

A 245-tonne dome lifted onto Hinkley Point C's first reactor, finishing the roof and enabling fit-out for a 2027 startup.

✅ 245-tonne steel dome lifted by Big Carl onto 44m-high reactor

✅ Indoor welding avoided weather defects seen at Flamanville

✅ Cost now £33bn; first power targeted by end of 2027

 

Engineers have lifted a steel roof onto a building which will house the first of two nuclear reactors at Hinkley Point in Somerset.

Hundreds of people helped with the delicate operation to get the 245-tonne steel dome into position.

It means the first reactor can be installed next year, ready to be switched on in June 2027.

Engineers at EDF said the "challenging job" was completed in just over an hour.

They first broke the ground on the new nuclear station in March 2017. Now, some 10,000 people work on what is Europe's largest building site.

Yet many analysts note that Europe is losing nuclear power even as demand for reliable energy grows.

They have faced delays from Covid restrictions and other recent setbacks, and the budget has doubled to £33bn, so getting the roof on the first of the two reactor buildings is a big deal.

EDF's nuclear island director Simon Parsons said it was a "fantastic night".

"Lifting the dome into place is a celebration of all the work done by a fantastic team. The smiles on people's faces this morning were something else.

"Now we can get on with the fitting of equipment, pipes and cables, including the first reactor which is on site and ready to be installed next year."

Nuclear minister Andrew Bowie hailed the "major milestone" in the building project, citing its role in the UK's green industrial revolution ambitions.

He said: "This is a key part of the UK Government's plans to revitalise nuclear."

But many still question whether Hinkley Point C will be worth all the money, especially after Hitachi's project freeze in Britain, with Roy Pumfrey of the Stop Hinkley campaign describing the project as "shockingly bad value".


Why lift the roof on?

The steel dome is bigger than the one on St Paul's Cathedral in London.

To lift it onto the 44-metre-high reactor building, they needed the world's largest land-based crane, dubbed Big Carl by engineers.

So why not just build the roof on top of the building?

The answer lies in a remote corner of Normandy in France, near a village called Flamanville.

EDF has been building a nuclear reactor there since 2007, ten years before they started in west Somerset.

The project is now a decade behind schedule and has still not been approved by French regulators.

Why? Because of cracks found in the precision welding on the roof of the reactor building.

In nuclear-powered France, they built the roof in situ, out in the open. 

Engineers have decided welding outside, exposed to wind and rain, compromised the high standards needed for a nuclear reactor.

So in Somerset they built a temporary workshop, which looks like a fair sized building itself. All the welding has been done inside, and then the completed roof was lifted into place.


Is it on time or on budget?

No, neither. When Hinkley C was first approved a decade ago, EDF said it would cost £14bn.

Four years later, in 2017, they finally started construction. By now the cost had risen to £19.5bn, and EDF said the plant would be finished by the end of 2025.

Today, the cost has risen to £33bn, and it is now hoped Hinkley C will produce electricity by the end of 2027.

"Nobody believes it will be done by 2027," said campaigner Roy Pumfrey.

"The costs keep rising, and the price of Hinkley's electricity will only get dearer," they added.

On the other hand, the increase in costs is not a problem for British energy bill payers, or the UK government.

EDF agreed to pay the full cost of construction, including any increases.

When I met Grant Shapps, then the UK Energy Secretary, at the site in April, he shrugged off the cost increases.

He said: "I think we should all be rather pleased it is not the British tax payer - it is France and EDF who are paying."

In return, the UK government agreed a set rate for Hinkley's power, called the Strike Price, back in 2013. The idea was this would guarantee the income from Hinkley Point for 35 years, allowing investors to get their money back.


Will it be worth the money?

Back in 2013, the Strike Price was set at £92.50 for each megawatt hour of power. At the time, the wholesale price of electricity was around £50/MWh, so Hinkley C looked expensive.

But since then, global shocks like the war in Ukraine have increased the cost of power substantially, and advocates argue next-gen nuclear could deliver smaller, cheaper, safer designs.

The Collapse of Electric Airplane Startup Eviation

Eviation Collapse underscores electric aviation headwinds, from Alice aircraft battery limits to FAA/EASA certification hurdles, funding shortfalls, and leadership instability, reshaping sustainability roadmaps for regional airliners and future zero-emission flight.

 

Key Points

Eviation Collapse is the 2025 shutdown of Eviation Aircraft, revealing battery, certification, and funding hurdles.

✅ Battery energy density limits curtailed Alice's range

✅ FAA/EASA certification timelines delayed commercialization

✅ Funding gaps and leadership churn undermined execution

 

The electric aviation industry was poised to revolutionize the skies through an aviation revolution with startups like Eviation Aircraft leading the charge to bring environmentally friendly, cost-efficient electric airplanes into commercial use. However, in a shocking turn of events, Eviation has faced an abrupt collapse, signaling challenges that may impact the future of electric flight.

Eviation’s Vision and Early Promise

Founded in 2015, Eviation was an ambitious electric airplane startup with the goal of changing the way the world thinks about aviation. The company’s flagship product, the Alice aircraft, was designed to be an all-electric regional airliner capable of carrying up to 9 passengers. With a focus on sustainability, reduced operating costs, and a quieter flight experience, Alice attracted attention as one of the most promising electric aircraft in development.

Eviation’s aircraft was aimed at replacing small, inefficient, and environmentally damaging regional aircraft, reducing emissions in the aviation industry. The startup’s vision was bold: to create an airplane that could offer all the benefits of electric power – lower operating costs, less noise, and a smaller environmental footprint. Their goal was not only to attract major airlines but also to pave the way for a more sustainable future in aviation.

The company’s early success was driven by substantial investments and partnerships. It garnered attention from aviation giants and venture capitalists alike, drawing support for its innovative technology. In fact, in 2019, Eviation secured a deal with the Israeli airline, El Al, for several aircraft, a deal that seemed to promise a bright future for the company.

Challenges in the Electric Aviation Industry

Despite its early successes and strong backing, Eviation faced considerable challenges that eventually contributed to its downfall. The electric aviation sector, as promising as it seemed, has always been riddled with hurdles – from battery technology to regulatory approvals, and compounded by Europe’s EV slump that dampened clean-transport sentiment, the path to producing commercially viable electric airplanes has proven more difficult than initially anticipated.

The first major issue Eviation encountered was the slow development of battery technology. While electric car companies like Tesla were able to scale their operations quickly during the electric vehicle boom due to advancements in battery efficiency, aviation technology faced a more significant obstacle. The energy density required for a plane to fly long distances with sufficient payload was far greater than what existing battery technology could offer. This limitation severely impacted the range of the Alice aircraft, preventing it from meeting the expectations set by its creators.

Another challenge was the lengthy regulatory approval process for electric aircraft. Aviation is one of the most regulated industries in the world, and getting a new aircraft certified for flight takes time and rigorous testing. Although Eviation’s Alice was touted as an innovative leap in aviation technology, the company struggled to navigate the complex process of meeting the safety and operational standards required by aviation authorities, such as the FAA and EASA.

Financial Difficulties and Leadership Changes

As challenges mounted, Eviation’s financial situation became increasingly precarious. The company struggled to secure additional funding to continue its development and scale operations. Investors, once eager to back the promising startup, grew wary as timelines stretched and costs climbed, amid a U.S. EV market share dip in early 2024, tempering enthusiasm. With the electric aviation market still in its early stages, Eviation faced stiff competition from more established players, including large aircraft manufacturers like Boeing and Airbus, who also began to invest heavily in electric and hybrid-electric aircraft technologies.

Leadership instability also played a role in Eviation’s collapse. The company went through several executive changes over a short period, and management’s inability to solidify a clear vision for the future raised concerns among stakeholders. The lack of consistent leadership hindered the company’s ability to make decisions quickly and efficiently, further exacerbating its financial challenges.

The Sudden Collapse

In 2025, Eviation made the difficult decision to shut down its operations. The company announced the closure after failing to secure enough funding to continue its development and meet its ambitious production goals. The sudden collapse of Eviation sent shockwaves through the electric aviation sector, where many had placed their hopes on the startup’s innovative approach to electric flight.

The failure of Eviation has left many questioning the future of electric aviation. While the industry is still in its infancy, Eviation’s downfall serves as a cautionary tale about the challenges of bringing cutting-edge technology to the skies. The ambitious vision of a sustainable, electric future in aviation may still be achievable, but the path to success will require overcoming significant technological, regulatory, and financial obstacles.

What’s Next for Electric Aviation?

Despite Eviation’s collapse, the electric aviation sector is far from dead. Other companies, such as Joby Aviation, Vertical Aerospace, and Ampaire, are continuing to develop electric and hybrid-electric aircraft, building on milestones like Canada’s first commercial electric flight that signal ongoing demand for green alternatives to traditional aviation.

Moreover, major aircraft manufacturers are doubling down on their own electric aircraft projects. Boeing, for example, has launched several initiatives aimed at reducing carbon emissions in aviation, while Harbour Air’s point-to-point e-seaplane flight showcases near-term regional progress, and Airbus is testing a hybrid-electric airliner prototype. The collapse of Eviation may slow down progress, but it is unlikely to derail the broader movement toward electric flight entirely.
