Food Waste to Green Hydrogen uses biological production to create clean energy, enabling waste-to-energy, decarbonization, and renewable hydrogen for electricity, industrial processes, and transport fuels, developed at Purdue University Northwest with Purdue Research Foundation licensing.

 

Key Points

A biological process converting food waste into renewable hydrogen for clean energy, electricity, industry, and transport.

✅ Enables rapid, scalable waste-to-hydrogen deployment

✅ Supports grid power, industrial heat, and mobility fuels

✅ Backed by patents, DOE grants, and licensing deals

 

West Lafayette, Indiana-based Purdue Research Foundation recently completed a licensing agreement with an international energy company – the name of which was not disclosed – for the commercialization of a new process discovered at Purdue University Northwest (PNW) for the biological production of green hydrogen from food waste. A second licensing agreement with a company in Indiana is under negotiation.


Food waste into green hydrogen
Researchers say that this new process, which uses food waste to biologically produce hydrogen, can be used as a clean energy source for producing electricity, as well as for chemical and industrial processes like green steel production or as a transportation fuel.

Robert Kramer, professor of physics at PNW and principal investigator for the research, says that more than 30% of all food, amounting to $48 billion, is wasted in the United States each year. That waste could be used to create hydrogen, a sustainable energy source alongside municipal solid waste power options. When hydrogen is combusted, the only byproduct is water vapor.

The developed process has a high production rate and can be implemented quickly to support large H2 energy systems in practice. The process is robust, reliable, and economically viable for local energy production and processes.

The research team has received five grants from the US Department of Energy and the Purdue Research Foundation totaling around $800,000 over the last eight years to develop the science and technology that led to this process, much like advances in advanced nuclear reactors drive clean energy innovation.

Two patents have been issued, and a third patent is currently in the final stages of approval. Over the next nine months, a scale-up test will be conducted, reflecting how power-to-gas storage can integrate with existing infrastructure. Based upon test results, it is anticipated that construction could start on the first commercial prototype within a year.

Last week, a facility designed to turn non-recyclable plastics into green hydrogen was approved in the UK, as other innovations like the seawater power concept progress globally. It is the second facility of its kind there.

Is residential solar worth it?

Home Solar Cost vs Utility Bills compares electricity rates, ROI, incentives, and battery storage, explaining payback, financing, and grid fees while highlighting long-term savings, rate volatility, and backup power resilience for homeowners.

 

Key Points

Compares home solar pricing and financing to utility rates, outlining savings, incentives, ROI, and backup power value.

✅ Average retail rates rose 59% in 20 years; volatility persists

✅ Typical 7.15 kW system costs $18,950 before incentives

✅ Federal ITC and state rebates improve ROI and payback

 

When shopping for a home solar system, sometimes the quoted price can leave you wondering why someone would move forward with something that seems so expensive. 

When compared with the status quo, electricity delivered from the utility, the price may not seem so high after all. First, pv magazine will examine the status quo, and how much you can expect to pay for power if you don’t get solar panels. Then, we will examine the average cost of solar arrays today and introduce incentives that boost home solar value.

The cost of doing nothing

Generally, early adopters have financially benefited from going solar by securing price certainty and stemming the impact of steadily increasing utility-bill costs, particularly for energy-insecure households who pay more for electricity.

End-use residential electric customers pay an average of $0.138/kWh in the United States, according to the Energy Information Administration (EIA). In California, that rate is $0.256/kWh, it averages $0.246/kWh across New England, $0.126/kWh in the South Atlantic region, and $0.124/kWh in the Mountain West region.

EIA reports that the average home uses 893 kWh per month, so based on the average retail rate of $0.138/kWh, that’s an electric bill of about $123 monthly, or $229 monthly in California.

Over the last 20 years, EIA data show that retail electricity prices have increased 59% across the United States, with evidence indicating that renewables are not making electricity more expensive, suggesting other factors have driven costs higher, or 2.95% each year.

This means based on historical rates, the average US homeowner can expect to pay $39,460 over the next 20 years on electricity bills. On average, Californians could pay $73,465 over 20 years.

Recent global events show just how unstable prices can be for commodities, and energy is no exception here, with solar panel sales doubling in the UK as homeowners look to cut soaring bills. What will your utility bill cost in 20 years?

These estimated bills also assume that energy use in the home is constant over 20 years, but as the United States electrifies its homes, adds more devices, and adopts electric vehicles, it is fair to expect that many homeowners will use more electricity going forward.

Another factor that may exacerbate rate raising is the upgrade of the national transmission grid. The infrastructure that delivers power to our homes is aging and in need of critical upgrades, and it is estimated that a staggering $500 billion will be spent on transmission buildout by 2035. This half-trillion-dollar cost gets passed down to homeowners in the form of raised utility bill rates.

The benefit of backup power may increase as time goes on as well. Power outages are on the rise across the United States, and recent assessments of the risk of power outages underscore that outages related to severe weather events have doubled in the last 20 years. Climate change-fueled storms are expected to continue to rise, so the role of battery backup in providing reliable energy may increase significantly.

The truth is, we don’t know how much power will cost in 20 years. Though it has increased 59% across the nation in the last 20 years, there is no way to be certain what it will cost going forward. That is where solar has a benefit over the status quo. By purchasing solar, you are securing price certainty going forward, making it easier to budget and plan for the future.

So how do these costs compare to going solar?

Cost of solar

As a general trend, prices for solar have fallen. In 2010, it cost about $40,000 to install a residential solar system, and since then, prices have fallen by as much as 70%, and about 37% in the last five years. However, prices have increased slightly in 2022 due to shipping costs, materials costs, and possible tariffs being placed on imported solar goods, and these pressures aren’t expected to be alleviated in the near-term.

When comparing quotes, the best metric for an apples-to-apples comparison is the cost per watt. Price benchmarking by the National Renewable Energy Laboratory shows the average cost per watt for the nation was $2.65/W DC in 2021, and the average system size was 7.15 kW. So, an average system would cost about $18,950. With 12.5 kWh of battery energy storage, the average cost was $4.26/W, representing an average price tag of $30,460 with batteries included.

The prices above do not include any incentives. Currently, the federal government applies a 26% investment tax credit to the system, bringing down system costs for those who qualify to $14,023 without batteries, and $22,540 with batteries. Compared to the potential $39,460 in utility bills, buying a solar system outright in cash appears to show a clear financial benefit.

Many homeowners will need financing to buy a solar system. Shorter terms can achieve rates as low as 2.99% or less, but financing for a 20-year solar loan typically lands between 5% to 8% or more. Based on 20-year, 7% annual percentage rate terms, a $14,000 system would total about $26,000 in loan payments over 20 years, and the system with batteries included would total about $42,000 in loan payments.

Often when you adopt solar, the utility will still charge you a grid access fee even if your system produces 100% of your needs. These vary from utility to utility but are often around $10 a month. Over 20 years, that equates to about $2,400 that you’ll still need to pay to the utility, plus any costs for energy you use beyond what your system provides.

Based on these average figures, a homeowner could expect to see as much as $12,000 in savings with a 20-year financed system. Homeowners in regions whose retail energy price exceeds the national average could see savings in multiples of that figure.

Though in this example batteries appear to be marginally more expensive than the status quo over a 20-year term, they improve the home by adding the crucial service of backup power, and as battery costs continue to fall they are increasingly being approved to participate in grid services, potentially unlocking additional revenue streams for homeowners.

Another thing to note is most solar systems are warranted for 25 years rather than the 20 used in the status quo example. A panel can last a good 35 years, and though it will begin to produce less in old age, any power produced by a panel you own is money back in your pocket.

Incentives and home value

Many states have additional incentives to boost the value of solar, too, and federal proposals to increase solar generation tenfold could remake the U.S. electricity system. Checking the Database of State Incentives for Renewables (DSIRE) will show the incentives available in your state, and a solar representative should be able to walk you through these benefits when you receive a quote. State incentives change frequently and vary widely, and in some cases are quite rich, offering thousands of dollars in additional benefits.

Another factor to consider is home value. A study by Zillow found that solar arrays increase a home value by 4.1% on average. For a $375,000 home, that’s an increase of $15,375 in value. In most states home solar is exempt from property taxes, making it a great way to boost value without paying taxes for it.

Bottom line

We’ve shared a lot of data on national averages and the potential cost of power going forward, but is solar for you? In the past, early adopters have been rewarded for going solar, and celebrate when they see $0 electric bills paid to the utility company.

Each home is different, each utility is different, and each homeowner has different needs, so evaluating whether solar is right for your home will take a little time and analysis. Representatives from solar companies will walk you through this analysis, and it’s generally a good rule of thumb to get at least three quotes for comparison.

A great resource for starting your research is the Solar Calculator developed by informational site SolarReviews. The calculator offers a quote and savings estimate based on local rates and incentives available to your area. The website also features reviews of installers, equipment, and more.

Some people will save tens of thousands of dollars in the long run with solar, while others may witness more modest savings. Solar will also provide the home clean, local energy, and U.S. solar generation is projected to reach 20% by 2050 as capacity expands, making an impact both on mitigating climate change and in supporting local jobs.

One indisputable benefit of solar is that it will offer greater clarity into what your electricity bills will cost over the next couple of decades, rather than leaving you exposed to whatever rates the utility company decides to charge in the future.

US Crosses the Electric-Car Tipping Point for Mass Adoption

EV Tipping Point signals the S-curve shift to mainstream adoption as new car sales pass 5%, with the US joining Europe and China; charging infrastructure, costs, and supply align to accelerate electric car market penetration.

 

Key Points

The EV tipping point is when fully electric cars reach about 5% of new sales, triggering rapid S-curve adoption.

✅ 5% of new car sales marks start of mass adoption

✅ Follows S-curve seen in phones, LEDs, internet

✅ Barriers ease: charging, cost declines, model availability

 

Many people of a certain age can recall the first time they held a smartphone. The devices were weird and expensive and novel enough to draw a crowd at parties. Then, less than a decade later, it became unusual not to own one.

That same society-altering shift is happening now with electric vehicles, according to a Bloomberg analysis of adoption rates around the world. The US is the latest country to pass what’s become a critical EV tipping point: an EV inflection point when 5% of new car sales are powered only by electricity. This threshold signals the start of mass EV adoption, the period when technological preferences rapidly flip, according to the analysis.

For the past six months, the US joined Europe and China — collectively the three largest car markets — in moving beyond the 5% tipping point, as recent U.S. EV sales indicate. If the US follows the trend established by 18 countries that came before it, a quarter of new car sales could be electric by the end of 2025. That would be a year or two ahead of most major forecasts.

How Fast Is the Switch to Electric Cars?
19 countries have reached the 5% tipping point, and an earlier-than-expected shift is underway—then everything changes

Why is 5% so important? 
Most successful new technologies — electricity, televisions, mobile phones, the internet, even LED lightbulbs — follow an S-shaped adoption curve, with EVs going from zero to 2 million in five years according to market data. Sales move at a crawl in the early-adopter phase, then surprisingly quickly once things go mainstream. (The top of the S curve represents the last holdouts who refuse to give up their old flip phones.)

Electric cars inline tout
In the case of electric vehicles, 5% seems to be the point when early adopters are overtaken by mainstream demand. Before then, sales tend to be slow and unpredictable, and still behind gas cars in most markets. Afterward, rapidly accelerating demand ensues.

It makes sense that countries around the world would follow similar patterns of EV adoption. Most impediments are universal: there aren’t enough public chargers, grid capacity concerns linger, the cars are expensive and in limited supply, buyers don’t know much about them. Once the road has been paved for the first 5%, the masses soon follow.

Thus the adoption curve followed by South Korea starting in 2021 ends up looking a lot like the one taken by China in 2018, which is similar to Norway after its first 5% quarter in 2013. The next major car markets approaching the tipping point this year include Canada, Australia, and Spain, suggesting that within a decade many drivers could be in EVs worldwide.

UK leads G20 for share of electricity sourced from wind

UK Wind Power Leadership in 2020 highlights record renewable energy growth, G20-leading wind share, rapid coal phase-out, and rising solar integration, advancing decarbonization targets under the Paris Agreement and momentum ahead of COP26.

 

Key Points

The UK led the G20 in wind power share in 2020, displacing coal, expanding solar, and cutting power-sector emissions.

✅ G20-leading wind share; second for combined wind and solar

✅ Fastest coal decline among G20 from 2015 to 2020

✅ Emissions risk rising as post-pandemic demand returns

 

Nearly a quarter of the UK’s electricity came from wind turbines in 2020 – making the country the leader among the G20 for share of power sourced from the renewable energy, a new analysis finds.

The UK also moved away from coal power at a faster rate than any other G20 country from 2015 to 2020, according to the results.

And it ranked second in the G20, behind Germany, for the proportion of electricity sourced from both wind and solar in 2020, after first surpassing coal in 2016.

“It’s crazy how much wind power has grown in the UK and how much it has offset coal, and how it’s starting to eat at gas,” Dave Jones, Ember’s global lead analyst, told The Independent.

But it is important to bear in mind that “we’re only doing a great job by the standards of the rest of the world”, he added, noting that low-carbon generation stalled in 2019 in the UK.

Ember’s Global Electricity Review notes that the world’s power sector emissions were two per cent higher in 2020 than in 2015 – the year that countries agreed to slash their greenhouse gas pollution as part of the Paris Agreement.

Power generated from coal fell by a record amount from 2019 to 2020, the analysis finds. However, this decline was greatly facilitated by lockdowns introduced to stop the spread of Covid-19, as global electricity demand was temporarily stifled before rebounding, the analysts say.

Coal is the most polluting of the fossil fuels. The UK government hopes to convince all countries to stop building new coal-fired power stations at Cop26, a climate conference that is to be held in Glasgow later this year.

UN chief Antonio Guterres has also called for all countries to end their “deadly addiction to coal”.

At a summit held earlier this month, he described ending the use of coal in electricity generation as the “single most important step” to meeting the Paris Agreement’s goal of limiting global warming to well below 2C above pre-industrial levels by 2100.

“There is definitely a concern that, in the pandemic year of 2020, coal hasn’t fallen as fast as it needed to,” said Mr Jones, even as the UK set coal-free power records recently.

“There is concern that, once electricity demand returns, we won’t be seeing that decline in coal anymore.”

New Brunswick announces rebate program for electric vehicles

New Brunswick EV Rebates deliver stackable provincial and federal incentives for electric vehicles, used EVs, and home chargers, supporting NB Power infrastructure, lower GHG emissions, and climate goals with fast chargers across the province.

 

Key Points

Stackable provincial and federal incentives up to $10,000 for EV purchases, plus support for home charging.

✅ $5,000 new EVs; $2,500 used; stackable with federal $5,000

✅ 50% home charger rebate up to $750 through NB Power

✅ Supports GHG cuts, charging network growth, climate targets

 

New Brunswickers looking for an electric vehicle (EV) can now claim up to $10,000 in rebates from the provincial and federal governments.

The three-year provincial program was announced Thursday and will give rebates of $5,000 on new EVs and $2,500 on used ones. It closely mirrors the federal program and is stackable, meaning new owners will be able to claim up to $5,000 from the feds as well.

Minister of Environment and Climate Change Gary Crossman said the move is hoped to kickstart the province’s push toward a target of having 20,000 EVs on the road by 2030.

“This incentive has to make a positive difference,” Crossman said.

“I truly believe people have been waiting for it, they’ve been asking about it, and this will make a difference from today moving forward to put new or used cars in their hands.”

The first year of the program will cost $1.95 million, which will come from the $36 million in the Climate Change Fund and will be run by NB Power, whose public charging network has been expanding across the province. The department says if the full amount is used this year it could represent a reduction of 850 tonnes of greenhouse gasses (GHGs) annually.

Both the Liberal and Green parties welcomed the move calling it long overdue, but Green MLA Kevin Arseneau said it’s not a “miracle solution.”

“Yes, we need to electrify cars, but this kind of initiative without proper funding of public transportation, urban planning for biking … without this kind of global approach this is just another swipe of a sword in water,” he said.

Liberal environment critic Francine Landry says she hopes this will make the difference for those considering the purchase of an EV and says the government should consider further methods of incentivization like waiving registration fees.

The province’s adoption of EVs has not been overly successful so far, reflecting broader Atlantic EV buying interest trends across the region. At the end of 2020, there were 646 EVs registered in the province, far short of the 2,500 target set out in the Climate Action Plan. That was up significantly from the 437 at the end of 2019, but still a long way from the goal.

New Brunswick has a fairly expansive network of charging stations across the province, claiming to be the first “fully-connected province” in the country, and had hoped that the available infrastructure, including plans for new fast-charging stations on the Trans-Canada, would push adoption of non-emitting vehicles.

“In 2017 we had 11 chargers in the province, so we’ve come a long way from an infrastructure standpoint which I think is critical to promoting or having an electric vehicle network, or a number of electric vehicles operating in the province, and neighbouring N.L.’s fast-charging network shows similar progress,” said Deputy Minister of Natural Resources Tom Macfarlane at a meeting of the standing committee on climate change and environmental stewardship in January of 2020.

There are now 172 level two chargers and 83 fast chargers, while Labrador’s EV infrastructure still lags in neighbouring N.L. today. Level two chargers take between six and eight hours to charge a vehicle, while the fast chargers take about half an hour to get to 80 per cent charge.

The newly announced program will also cover 50 per cent of costs for a home charging station up to $750, similar to B.C. charger rebates that support home infrastructure, to further address infrastructure needs.

The New Brunswick Lung Association is applauding the rebate plan.

President and CEO Melanie Langille said about 15,000 Canadians, including 40 people from New Brunswick, die prematurely each year from air pollution. She said vehicle emissions account for about 30 per cent of the province’s air pollution.

“Electric vehicles are critical to reducing our greenhouse gas emissions,” said Langille. “New Brunswick has one of the highest per capita GHG emissions in Canada. But, because our electricity source in New Brunswick is primarily from non-emitting sources and regional initiatives like Nova Scotia’s vehicle-to-grid pilot are advancing grid integration, switching to an EV is an effective way for New Brunswickers to lower their GHG emissions.”

Langille said the lung association has been part of an electric vehicles advisory group in the province since 2014 and its research has shown this type of program is needed.

“The major barrier that is standing in the way of New Brunswickers adopting electric vehicles is the upfront costs,” Langille said. “So today’s announcement, and that it can be stacked on top of the existing federal rebates, is a huge step forward for us.”

The Age of Electric Cars Is Dawning Ahead of Schedule

EV Price Parity is nearing reality in Europe as subsidies, falling battery costs, higher energy density, and expanding charging infrastructure push Tesla, Volkswagen, and Renault to compete under EU CO2 regulations and fleet targets.

 

Key Points

EV price parity means EVs match ICE cars on total ownership cost as subsidies fade and batteries get cheaper.

✅ Battery pack costs trending toward $100/kWh

✅ EU CO2 rules and incentives accelerate adoption

✅ Charging networks reduce range anxiety and TCO

 

An electric Volkswagen ID.3 for the same price as a Golf. A Tesla Model 3 that costs as much as a BMW 3 Series. A Renault Zoe electric subcompact whose monthly lease payment might equal a nice dinner for two in Paris.

As car sales collapsed in Europe because of the pandemic, one category grew rapidly: electric vehicles, a shift that some analysts say could put most drivers within a decade on battery power. One reason is that purchase prices in Europe are coming tantalizingly close to the prices for cars with gasoline or diesel engines.

At the moment this near parity is possible only with government subsidies that, depending on the country, can cut more than $10,000 from the final price. Carmakers are offering deals on electric cars to meet stricter European Union regulations on carbon dioxide emissions. In Germany, an electric Renault Zoe can be leased for 139 euros a month, or $164.

Electric vehicles are not yet as popular in the United States, largely because government incentives are less generous, but an emerging American EV boom could change that trajectory. Battery-powered cars account for about 2 percent of new car sales in America, while in Europe the market share is approaching 5 percent. Including hybrids, the share rises to nearly 9 percent in Europe, according to Matthias Schmidt, an independent analyst in Berlin.

As electric cars become more mainstream, the automobile industry is rapidly approaching the tipping point, an inflection point for the market, when, even without subsidies, it will be as cheap, and maybe cheaper, to own a plug-in vehicle than one that burns fossil fuels. The carmaker that reaches price parity first may be positioned to dominate the segment.

A few years ago, industry experts expected 2025 would be the turning point. But technology is advancing faster than expected, and could be poised for a quantum leap. Elon Musk is expected to announce a breakthrough at Tesla’s “Battery Day” event on Tuesday that would allow electric cars to travel significantly farther without adding weight.

The balance of power in the auto industry may depend on which carmaker, electronics company or start-up succeeds in squeezing the most power per pound into a battery, what’s known as energy density. A battery with high energy density is inherently cheaper because it requires fewer raw materials and less weight to deliver the same range.

“We’re seeing energy density increase faster than ever before,” said Milan Thakore, a senior research analyst at Wood Mackenzie, an energy consultant which recently pushed its prediction of the tipping point ahead by a year, to 2024.

Some industry experts are even more bullish. Hui Zhang, managing director in Germany of NIO, a Chinese electric carmaker with global ambitions, said he thought parity could be achieved in 2023.

Venkat Viswanathan, an associate professor at Carnegie Mellon University who closely follows the industry, is more cautious, though EV revolution skeptics argue the revolution is overstated. But he said: “We are already on a very accelerated timeline. If you asked anyone in 2010 whether we would have price parity by 2025, they would have said that was impossible.”

This transition will probably arrive at different times for different segments of the market. High-end electric vehicles are pretty close to parity already. The Tesla Model 3 and the gas-powered BMW 3 Series both sell for about $41,000 in the United States.

A Tesla may even be cheaper to own than a BMW because it never needs oil changes or new spark plugs and electricity is cheaper, per mile, than gasoline. Which car a customer chooses is more a matter of preference, particularly whether an owner is willing to trade the convenience of gas stations for charging points that take more time. (On the other hand, owners can also charge their Teslas at home.)

Consumers tend to focus on sticker prices, and it will take longer before unsubsidized electric cars cost as little to drive off a dealer’s lot as an economy car, even for shoppers weighing whether it’s the right time to buy an electric car now.

The race to build a better battery
The holy grail in the electric vehicle industry has been to push the cost of battery packs — the rechargeable system that stores energy — below $100 per kilowatt-hour, the standard measure of battery power. That is the point, more or less, at which propelling a vehicle with electricity will be as cheap as it is with gasoline.

Current battery packs cost around $150 to $200 per kilowatt-hour, depending on the technology. That means a battery pack costs around $20,000. But the price has dropped 80 percent since 2008, according to the United States Department of Energy.

All electric cars use lithium-ion batteries, but there are many variations on that basic chemistry, and intense competition to find the combination of materials that stores the most power for the least weight.

For traditional car companies, this is all very scary. Internal combustion engines have not changed fundamentally for decades, but battery technology is still wide open. There are even geopolitical implications. China is pouring resources into battery research, seeing the shift to electric power as a chance for companies like NIO to make their move on Europe and someday, American, markets. In less than a decade, the Chinese battery maker CATL has become one of the world’s biggest manufacturers.


Everyone is trying to catch Tesla
The California company has been selling electric cars since 2008 and can draw on years of data to calculate how far it can safely push a battery’s performance without causing overheating or excessive wear. That knowledge allows Tesla to offer better range than competitors who have to be more careful. Tesla’s four models are the only widely available electric cars that can go more than 300 miles on a charge, according to Kelley Blue Book.

On Tuesday, Mr. Musk could unveil a technology offering 50 percent more storage per pound at lower cost, according to analysts at the Swiss bank UBS. If so, competitors could recede even further in the rearview mirror.

“The traditional car industry is still behind,” said Peter Carlsson, who ran Tesla’s supplier network in the company’s early days and is now chief executive of Northvolt, a new Swedish company that has contracts to manufacture batteries for Volkswagen and BMW.

“But,” Mr. Carlsson said, “there is a massive amount of resources going into the race to beat Tesla. A number, not all, of the big carmakers are going to catch up.”

The traditional carmakers’ best hope to avoid oblivion will be to exploit their expertise in supply chains and mass production to churn out economical electrical cars by the millions.

A key test of the traditional automakers’ ability to survive will be Volkswagen’s new battery-powered ID.3, which will start at under €30,000, or $35,000, after subsidies and is arriving at European dealerships now. By using its global manufacturing and sales network, Volkswagen hopes to sell electric vehicles by the millions within a few years. It plans to begin selling the ID.4, an electric sport utility vehicle, in the United States next year. (ID stands for “intelligent design.”)

But there is a steep learning curve.

“We have been mass-producing internal combustion vehicles since Henry Ford. We don’t have that for battery vehicles. It’s a very new technology,” said Jürgen Fleischer, a professor at the Karlsruhe Institute of Technology in southwestern Germany whose research focuses on battery manufacturing. “The question will be how fast can we can get through this learning curve?”

It’s not just about the batteries
Peter Rawlinson, who led design of the Tesla Model S and is now chief executive of the electric car start-up Lucid, likes to wow audiences by showing up at events dragging a rolling carry-on bag containing the company’s supercompact drive unit. Electric motor, transmission and differential in one, the unit saves space and, along with hundreds of other weight-saving tweaks, will allow the company’s Lucid Air luxury car — which the company unveiled on Sept. 9 — to travel more than 400 miles on a charge, Mr. Rawlinson said.

His point is that designers should focus on things like aerodynamic drag and weight to avoid the need for big, expensive batteries in the first place. “There is kind of a myopia,” Mr. Rawlinson said. “Everyone is talking about batteries. It’s the whole system.”

“We have been mass-producing internal combustion vehicles since Henry Ford,” said Jürgen Fleischer, a professor at the Karlsruhe Institute of Technology. “We don’t have that for battery vehicles.”

A charger on every corner would help
When Jana Höffner bought an electric Renault Zoe in 2013, driving anywhere outside her home in Stuttgart was an adventure. Charging stations were rare, and didn’t always work. Ms. Höffner drove her Zoe to places like Norway or Sicily just to see if she could make it without having to call for a tow.

Ms. Höffner, who works in online communication for the state of Baden-Württemberg, has since traded up to a Tesla Model 3 equipped with software that guides her to the company’s own network of chargers, which can fill the battery to 80 percent capacity in about half an hour. She sounds almost nostalgic when she remembers how hard it was to recharge back in the electric-vehicle stone age.

“Now, it’s boring,” Ms. Höffner said. “You say where you want to go and the car takes care of the rest.”

The European Union has nearly 200,000 chargers, far short of the three million that will be needed when electric cars become ubiquitous, according to Transport & Environment, an advocacy group. The United States remains far behind, with less than half as many as Europe, even as charging networks jostle under federal electrification efforts.

But the European network is already dense enough that owning and charging an electric car is “no problem,” said Ms. Höffner, who can’t charge at home and depends on public infrastructure.

IEA: Clean energy investment significantly outpaces fossil fuels

Clean Energy Investment is surging as renewables, electric vehicles, grids, storage, and nuclear outpace fossil fuels, driven by energy security, affordability, and policies like the Inflation Reduction Act, the IEA's World Energy Investment report shows.

 

Key Points

Investment in renewables, EVs, grids, and storage now surpasses fossil fuels amid cost and security pressures.

✅ $1.7T to clean tech vs just over $1T to fossil fuels this year.

✅ For every $1 in fossil, about $1.7 goes to clean energy.

✅ Solar investment poised to overtake oil production spending.

 

Investment in clean energy technologies is significantly outpacing spending on fossil fuels as affordability and security concerns, underpinned by analyses showing renewables cheapest new power in many markets, triggered by the global energy crisis strengthen the momentum behind more sustainable options, according to the International Energy Agency's (IEA) latest World Energy Investment report.

About $2.8 trillion (€2.6 trillion) is set to be invested globally in energy this year, of which over $1.7 trillion (€1.59 trillion) is expected to go to clean technologies - including renewables, electric vehicles, nuclear power, grids, storage, low-emissions fuels, efficiency improvements and heat pumps – according to report.

The remainder, slightly more than $1 trillion (€937.7 billion), is going to coal, gas and oil, despite growing calls for a fossil fuel lockdown to meet climate goals.

Annual clean energy investment is expected to rise by 24% between 2021 and 2023, driven by renewables and electric vehicles, with renewables breaking records worldwide over the same period.

But more than 90% of this increase comes from advanced economies and China, which the IEA said presents a serious risk of new dividing lines in global energy if clean energy transitions don’t pick up elsewhere.

“Clean energy is moving fast – faster than many people realise. This is clear in the investment trends, where clean technologies are pulling away from fossil fuels,” said IEA executive director Fatih Birol. “For every dollar invested in fossil fuels, about 1.7 dollars are now going into clean energy. Five years ago, this ratio was one-to-one. One shining example is investment in solar, which is set to overtake the amount of investment going into oil production for the first time.”

Led by solar, low-emissions electricity technologies are expected to account for almost 90% of investment in power generation, reflecting the global renewables share above 30% in electricity markets.

Consumers are also investing in more electrified end-uses. Global heat pump sales have seen double-digit annual growth since 2021. Electric vehicle sales are expected to leap by a third this year after already surging in 2022.

Clean energy investments have been boosted by a variety of factors in recent years, including periods of strong economic growth and volatile fossil fuel prices that raised concerns about energy security, and insights from the IRENA decarbonisation report that underscore broader benefits, especially following Russia’s invasion of Ukraine.

Furthermore, enhanced policy support through major actions like the US Inflation Reduction Act and initiatives in Europe's green surge, Japan, China and elsewhere have played a role.

In Ireland, more than a third of electricity is expected to be green within four years, illustrating national progress.

The biggest shortfalls in clean energy investment are in emerging and developing economies, the IEA added. It pointed to some bright spots, such as dynamic investments in solar in India and in renewables in Brazil and parts of the Middle East. However, investment in many countries is being held back by factors including higher interest rates, unclear policy frameworks and market designs, weak grid infrastructure, financially strained utilities and a high cost of capital.

"Much more needs to be done by the international community, especially to drive investment in lower-income economies, where the private sector has been reluctant to venture," according to the IEA.
