Electric Vehicle Ownership Costs include lower maintenance, repair, and fuel expenses; Consumer Reports shows BEV and PHEV TCO beats ICE over 200,000 miles, with per-mile savings compounding through electricity prices and reduced service.

 

Key Points

Lifetime EV expenses, typically lower than ICE, due to cheaper electricity, reduced maintenance, and fewer repairs.

✅ BEV: $0.012/mi to 50k; $0.028/mi after; vs ICE up to $0.06/mi

✅ PHEV: $0.021/mi to 50k; $0.031/mi after; still below ICE

✅ Savings increase over 200k miles from fuel and service reductions

 

Electric vehicles are a relatively new technology, and the EV age is arriving ahead of schedule today. Even though we technically saw the first battery-powered vehicles more than 100 years ago, they haven’t really become viable transportation in the modern world until recently, and they are greener than ever in all 50 states as the grid improves.

As viable as they may now be, however, it still seems they’re unarguably more expensive than their conventional internal-combustion counterparts, prompting many to ask whether it’s time to buy an electric car today. Well, until now.

Lower maintenence costs and the lower price of electricity versus gasoline (see the typical cost to charge an electric vehicle in most regions) actually make electric cars much cheaper in the long run, despite their often higher purchase price, according to a new survey by Consumer Reports. The information was collected using annual reliability surveys conducted by CR in 2019 and 2020.

In the first 50,000 miles (80,500 km), battery electric vehicles cost just US$0.012 per mile for maintenence and repairs, while plug-in hybrid models bump that number up to USD$0.021. Compare these numbers to the typical USD$0.028 cost for internal combustion vehicles, and it becomes clear the more you drive, the more you will save, and across the U.S. plug-ins logged 19 billion electric miles in 2021 to prove the point. After 50,000 miles, the costs for BEV and PHEV vehicles is US$0.028 and US$0.031 respectively, while ICE vehicles jump to US$0.06 per mile.

To put it more practically, if you chose to buy a Model 3 instead of a BMW 330i, you’d see a total US$17,600 in savings over the lifetime of the vehicle, aligning with evidence that EVs are better for the planet and your budget as well, based on average driving. In the SUV sector, buying a Tesla Model Y instead of a Lexus crossover would save US$13,400 (provided the former’s roof doesn’t fly off) and buying a Nissan Leaf over a Honda Civic would save US$6,000 over the lifetime of the vehicles.

CR defines the vehicle’s “lifetime” as 200,000 miles (320,000 km). Ergo the final caveat: while it sounds like driving electric means big savings, you might only see those returns after quite a long period of ownership, though some forecasts suggest that within a decade adoption will be nearly universal for many drivers.

The American EV boom is about to begin. Does the US have the power to charge it?

EV Charging Infrastructure accelerates with federal funding, NEVI corridors, and Level 2/3 DC fast charging to cut range anxiety, support apartment dwellers, and scale to 500,000 public chargers alongside tax credits and state mandates.

 

Key Points

The network of public and private hardware, software, and policies enabling reliable Level 2/3 EV charging at scale.

✅ $7,500/$4,000 tax credits spur adoption and charger demand

✅ NEVI funding builds 500,000 public, reliable DC fast chargers

✅ Equity focus: apartment, curbside, bidirectional and inductive tech

 

Speaking in front of a line of the latest electric vehicles (EVs) at this month’s North American International Auto Show, President Joe Biden declared: “The great American road trip is going to be fully electrified.”

Most vehicles on the road are still gas guzzlers, but Washington is betting big on change, with EV charging networks competing to expand as it hopes that major federal investment will help reach a target set by the White House for 50% of new cars to be electric by 2030. But there are roadblocks – specifically when it comes to charging them all. “Range anxiety,” or how far one can travel before needing to charge, is still cited as a major deterrent for potential EV buyers.

The auto industry recently passed the 5% mark of EV market share – a watershed moment, arriving ahead of schedule according to analysts, before rapid growth. New policies at the state and local level could very well spur that growth: the Inflation Reduction Act, which passed this summer, offers tax credits of $4,000 to purchase a used EV and up to $7,500 for certain new ones. In August, California, the nation’s largest state and economy, announced rules that would ban all new gas-powered cars by 2035, as part of broader grid stability efforts in the state. New York plans to follow.

So now, the race is on to provide chargers to power all those new EVs.

The administration’s target of 500,000 public charging units by 2030 is a far cry from the current count of nearly 50,000, according to the Department of Energy’s estimate. And those new chargers will have to be fast – what’s known as Level 2 or 3 charging – and functional in order to create a truly reliable system, even as state power grids face added demands across regions. Today, many are not.

Last week, the White House approved plans for all 50 states, along with Washington DC, and Puerto Rico, to set up chargers along highways, unlocking $1.5bn in federal funding to that end, as US automakers’ charger buildout to complement public funds. The money comes from the landmark infrastructure bill passed last year, which invests $7.5bn for EV charging in total.

But how much of that money is spent is largely going to be determined at the local level, amid control over charging debates among stakeholders. “It’s a difference between policy and practice,” said Drew Lipsher, the chief development officer at Volta, an EV charging provider. “Now that the federal government has these policies, the question becomes, OK, how does this actually get implemented?” The practice, he said, is up to states and municipalities.

As EV demand spikes, a growing number of cities are adopting policies for EV charging construction. In July, the city of Columbus passed an “EV readiness” ordinance, which will require new parking structures to host charging stations proportionate to the number of total parking spots, with at least one that is ADA-accessible. Honolulu and Atlanta have passed similar measures.

One major challenge is creating a distribution model that can meet a diversity of needs.

At the moment, most EV owners charge their cars at home with a built-in unit, which governments can help subsidize. But for apartment dwellers or those living in multi-family homes, that’s less feasible. “When we’re thinking about the largest pieces of the population, that’s where we need to really be focusing our attention. This is a major equity issue,” said Alexia Melendez Martineau, the policy manager at Plug-In America, an EV consumer advocacy group.

Bringing power to people is one such solution. In Hoboken, New Jersey, Volta is working with the city to create a streetside charging network. “The network will be within a five-minute walk of every resident,” said Lipsher. “Hopefully this is a way for us to really import it to cities who believe public EV charging infrastructure on the street is important.” Similarly, in parts of Los Angeles – as in Berlin and London – drivers can get a charge from a street lamp.

And there may be new technologies that could help, exciting experts and EV enthusiasts alike. That could include the roads themselves charging EVs through a magnetizable concrete technology being piloted in Indiana and Detroit. And bidirectional charging, where, similar to solar panels, drivers can put their electricity back into the grid – or perhaps even to another EV, through what’s known as electric vehicle supply equipment (EVSE). Nissan approved the technology for their Leaf model this month.

What to know about DOE's hydrogen hubs

U.S. Clean Hydrogen Hubs aim to scale production, storage, transport, and use as DOE and the Biden administration fund regional projects under the infrastructure law, blending green and blue hydrogen, carbon capture, renewables, and pipelines.

 

Key Points

Federally funded regional projects to make, move, and use low-carbon hydrogen via green, blue, and pink routes.

✅ $7B DOE funding via infrastructure law

✅ Mix of green, blue, pink hydrogen pathways

✅ Targets 10M metric tons annually by 2030

 

New details are emerging about the Biden administration’s landmark plans to build out a U.S. clean hydrogen industry.

On Friday, the Department of Energy named the seven winners of $7 billion in federal funds to establish regional hydrogen hubs. The hubs — funded through the infrastructure law — are part of the administration’s efforts to jump-start an industry it sees as key to achieving climate goals like the goal of 100 percent clean electricity by 2035 set by the administration. The aim is to demonstrate everything from the production and storage of hydrogen to its transport and consumption.

“All across the country, from coast to coast, in the heartland, we’re building a clean energy future here in America, not somewhere else,” President Joe Biden said while announcing the hubs in Philadelphia.

From 79 initial proposals, DOE chose the following: the Mid-Atlantic Hydrogen Hub, Appalachian Hydrogen Hub, California Hydrogen Hub, Gulf Coast Hydrogen Hub, Heartland Hydrogen Hub, Midwest Hydrogen Hub and Pacific Northwest Hydrogen Hub.

Many of the winning proposals are backed by state government leaders and industry partners, and by Southeast cities that have ramped up clean energy purchases in recent years as well. The Midwest hub, for example, is a coalition of Illinois, Indiana and Michigan — supported by politicians like Illinois Gov. J.B. Pritzker (D), as well as such companies as Air Liquide, Ameren Illinois and Atlas Agro. The mid-Atlantic hub is supported by Democratic members of Congress representing the region, including Delaware Sens. Chris Coons and Tom Carper and Rep. Lisa Blunt Rochester.

The administration hopes the hubs will produce 10 million metric tons of “clean” hydrogen annually by 2030. But much about the projects remains unknown — including how trends like cheap batteries for solar could affect clean power supply — and dependent on negotiations with DOE.


A win for ‘blue’ hydrogen?
Nearly all hydrogen created in the U.S. today is extracted from natural gas through steam methane reformation. The emissions-intensive process produces what is known as “grey” hydrogen — or “blue” hydrogen when combined with carbon capture and storage.

Four recipients — the Appalachian, Gulf Coast, Heartland and Midwest hydrogen hubs — include blue hydrogen in their plans, though the infrastructure law only mandated one.

That has drawn the ire of environmentalists, who argue blue hydrogen is not emissions-free, partly because of the potential for methane leaks during the production process.

“This is worse than expected,” Clean Energy Group President Seth Mullendore said after the recipients were announced Friday. “The fact that more than half the hubs will be using fossil gas is outrageous.”

Critics have also pointed out that many of the industry partners backing the hub projects include oil and gas companies. The coalitions are a mix of private-sector groups — often including renewable energy developers — and government stakeholders. Proposals have also looped in universities, utilities, environmental groups, community organizations, labor unions and tribal nations, among others.

“The massive build out of hydrogen infrastructure is little more than an industry ploy to rebrand fracked gas,” said Food & Water Watch Policy Director Jim Walsh in a statement Friday. “In a moment when every political decision that we make must reject fossil expansion, the Biden administration is going in the opposite direction.”

The White House has emphasized that roughly two-thirds of the $7 billion pot is “associated” with the production of “green” hydrogen, which uses electricity from renewable sources. Two of the chosen proposals — in California and the Pacific Northwest — are making green hydrogen their focus, reflecting advances such as offshore green hydrogen being pursued by industry leaders, while three other hubs plan to include green hydrogen alongside hydrogen made with natural gas (blue) or nuclear energy (pink).

Many hubs plan to use several methods for hydrogen production, and globally, projects like Brazil's green hydrogen plant highlight the scale of investment, but the exact mix may change depending on which projects make it through the DOE negotiations process. The Midwest hub, for example, told E&E News it’s pursuing an “all-of-the-above” strategy and has projects for green, blue and “pink” hydrogen. The mid-Atlantic hub in southeastern Pennsylvania, Delaware and New Jersey will also generate hydrogen with nuclear reactors.

Energy Secretary Jennifer Granholm has described clean hydrogen as a fresh business opportunity, especially for the natural gas industry, which has supported the concept of sending hydrogen to market through its pipeline network. Lawmakers like Sen. Joe Manchin (D-W.Va.) — who said the Appalachian hub will make West Virginia the “new epicenter of hydrogen” — have pushed for continuing to use natural gas to make hydrogen in his state.

“Natural gas utilities are committed to exploring all options for emissions reduction as demonstrated by the 39 hydrogen pilot projects already underway and are eager to participate in a number of the hubs,” said American Gas Association President and CEO Karen Harbert in a statement Friday.

Green hydrogen also has faced criticism. Some groups argue that the renewable resources needed to produce green hydrogen are limited, even with sources such as wind, solar and hydropower technology, so funding should be reserved for applications that cannot be easily electrified, mostly industrial processes. There also is uncertainty about how the Treasury Department will handle hydrogen made from grid electricity — which can include power from fossil fuel plants — in its upcoming guidance on the first-ever tax credit for clean hydrogen production.

“Even the cleanest forms of hydrogen present serious problems,” Walsh said. “As groundwater sources are drying up across the country, there is no reason to waste precious drinking water resources on hydrogen when there are cheaper, cleaner energy sources that can facilitate a real transition off fossil fuels.”

But Angelina Galiteva, CEO of the hub in drought-prone California, said hydrogen will enable the state “to increase renewable penetration to reach all corners of the economy,” noting parallel initiatives such as Dubai's solar hydrogen plans that illustrate the potential.

“Transitioning to renewable clean hydrogen will pose significantly less stress on water resources than remaining on the current fossil path,” she said.

California Wants Cars to Run on Electricity. It’s Going to Need a Much Bigger Grid

California EV mandate will phase out new gas cars, raising power demand and requiring renewable energy, grid upgrades, fast chargers, time-of-use rates, and vehicle-to-grid to stabilize loads and reduce emissions statewide.

 

Key Points

California's order ends new gas-car sales by 2035, driving grid upgrades, charging infrastructure, and cleaner transport.

✅ 25% higher power demand requires new generation and storage

✅ Time-of-use pricing and midday charging reduce grid stress

✅ Vehicle-to-grid and falling battery costs enable reliability

 

Leaning on the hood of a shiny red electric Ford Mustang, California Gov. Gavin Newsom signed an executive order Wednesday to end the sale of new gas-burning cars in his state in 15 years, a move with looming challenges for regulators and industry.

Now comes the hard part.

Energy consultants and academics say converting all passenger cars and trucks to run on electricity in California could raise power demand by as much as 25%. That poses a major challenge to state power grids as California is already facing periodic rolling blackouts as it rapidly transitions to renewable energy.

California will need to boost power generation, scale up its network of fast charging stations, enhance its electric grid to handle the added load and hope that battery technology continues to improve enough that millions in America’s most populous state can handle long freeway commutes to schools and offices without problems.

“We’ve got 15 years to do the work,” said Pedro Pizarro, chief executive of Edison International, owner of Southern California Edison, a utility serving 15 million people in the state. “Frankly the state agencies are going to have to do their part. We’ve got to get to the permitting processes, the approvals; all of that work is going to have to get accelerated to meet [Wednesday’s] target.”

Switching from petroleum fuels to electricity to phase out the internal combustion engine won’t happen all at once—Mr. Newsom’s order applies to sales of new vehicles, so older gas-powered cars will be on the road in California for many years to come. But the mandate means the state will face a growing demand for megawatts.

California is already facing a shortfall of power supplies over the next couple of years. The problem was highlighted last month when a heat wave blanketed the western U.S. and the state’s grid operator instituted rolling blackouts on two occasions.

“It is too early to tell what kind of impact the order will have on our power grid, and we don’t have any specific analysis or projections,” said Anne Gonzalez, a spokeswoman for the California Independent System Operator, which runs the grid.

Currently, California faces a crunchtime in the early evening as solar power falls off and demand to power air conditioners remains relatively high. Car charging presents a new potential issue: what happens if surging demand threatens to crash the grid during peak hours?

Caroline Winn, the chief executive of San Diego Gas & Electric, a utility owned by Sempra Energy that serves 3.6 million people, said there will need to be rules and rates that encourage people to charge their cars at certain times of the day, amid broader control over charging debates.

“We need to get the rules right and the markets right, informed by lessons from 2021, in order to resolve this issue because certainly California is moving that way,” she said.

The grid will need to be upgraded to prepare for millions of new electric vehicles. The majority of people who own them usually charge them at home, which would mean changes to substations and distribution circuits to accommodate multiple homes in a neighborhood drawing power to fill up batteries. The state’s three main investor-owned utilities are spending billions of dollars to harden the grid to prevent power equipment from sparking catastrophic wildfires.


“We have a hell of a lot of work to do nationally. California is ahead of everybody and they have a hell of a lot of work to do,” said Chris Nelder, who studies EV-grid integration at the Rocky Mountain Institute, an energy and environment-policy organization that promotes clean-energy solutions.

Mr. Nelder believes the investment will be worth it, because internal combustion engines generate so much waste heat and emissions of uncombusted hydrocarbons that escape out of tailpipes. Improving energy efficiency by upgrading the electrical system could result in lower bills for customers. “We will eliminate a vast amount of waste from the energy system and make it way more efficient,” he said.

Some see the growth of electric vehicles as an opportunity more than a challenge. In the afternoon, when electricity demand is high but the sun is setting and solar power drops off quickly, batteries in passenger cars, buses and other vehicles could release power back into the electric grid to help grid stability across the system, said Matt Petersen, chairman of the Transportation Electrification Partnership, a public-private effort in Los Angeles to accelerate the deployment of electric vehicles.

The idea is known as “vehicle-to-grid” and has been discussed in a number of countries expanding EV use, including the U.K. and Denmark.

“We end up with rolling batteries that can discharge power when needed,” Mr. Petersen said, adding, “The more electric vehicles we add to the grid, the more renewable energy we can add to the grid.”

One big hurdle for the widespread deployment of electric cars is driving down the cost of batteries to make the cars more affordable. This week, Tesla Inc. Chief Executive Elon Musk said he expected to have a $25,000 model ready by about 2023, signaling a broader EV boom in the U.S.

Shirley Meng, director of the Sustainable Power and Energy Center at the University of California, San Diego, said she believed batteries would continue to provide better performance at a lower cost.

“I am confident the battery technology is ready,” she said. Costs are expected to fall as new kinds of materials and metals can be used in the underlying battery chemistry, dropping prices. “Batteries are good now, and they will be better in the next 10 years.”

John Eichberger, executive director of the Fuels Institute, a nonprofit research group launched by the National Association of Convenience Stores, said he hoped that the California Air Resources Board, which is tasked with developing new rules to implement Mr. Newsom’s order, will slow the timeline if the market and electric build-out is running behind.

“We need to think about these critical infrastructure issues because transportation is not optional,” he said. “How do we develop a system that can guarantee consumers that they can get the energy when they need it?”

NREL’s Electric Vehicle Infrastructure Projection Tool Helps Utilities, Agencies, and Researchers Predict Hour-by-Hour Impact of Charging on the Grid

EVI-Pro Lite EV Load Forecasting helps utilities model EV charging infrastructure, grid load shapes, and resilient energy systems, factoring home, workplace, and public charging behavior to inform planning, capacity upgrades, and flexible demand strategies.

 

Key Points

A NREL tool projecting EV charging demand and load shapes to help utilities plan the grid and right-size infrastructure.

✅ Visualizes weekday/weekend EV load by charger type.

✅ Tests home, workplace, and public charging access scenarios.

✅ Supports utility planning, demand flexibility, and capacity upgrades.

 

As electric vehicles (EVs) continue to grow in popularity, utilities and community planners are increasingly focused on building resilient energy systems that can support the added electric load from EV charging, including a possible EV-driven demand increase across the grid.

But forecasting the best ways to adapt to increased EV charging can be a difficult task as EV adoption will challenge state power grids in diverse ways. Planners need to consider when consumers charge, how fast they charge, and where they charge, among other factors.

To support that effort, researchers at the National Renewable Energy Laboratory (NREL) have expanded the Electric Vehicle Infrastructure Projection (EVI-Pro) Lite tool with more analytic capabilities. EVI-Pro Lite is a simplified version of EVI-Pro, the more complex, original version of the tool developed by NREL and the California Energy Commission to inform detailed infrastructure requirements to support a growing EV fleet in California, where EVs bolster grid stability through coordinated planning.

EVI-Pro Lite’s estimated weekday electric load by charger type for El Paso, Texas, assuming a fleet of 10,000 plug-in electric vehicles, an average of 35 daily miles traveled, and 50% access to home charging, among other variables, as well as potential roles for vehicle-to-grid power in future scenarios. The order of the legend items matches the order of the series stacked in the chart.

Previously, the tool was limited to letting users estimate how many chargers and what kind of chargers a city, region, or state may need to support an influx of EVs. In the added online application, those same users can take it a step further to predict how that added EV charging will impact electricity demand, or load shapes, in their area at any given time and inform grid coordination for EV flexibility strategies.

“EV charging is going to look different across the country, depending on the prevalence of EVs, access to home charging, and the kind of chargers most used,” said Eric Wood, an NREL researcher who led model development. “Our expansion gives stakeholders—especially small- to medium-size electric utilities and co-ops—an easy way to analyze key factors for developing a flexible energy strategy that can respond to what’s happening on the ground.”

Tools to forecast EV loads have existed for some time, but Wood said that EVI-Pro Lite appeals to a wider audience, including planners tracking EVs' impact on utilities in many markets. The tool is a user-friendly, free online application that displays a clear graphic of daily projected electric loads from EV charging for regions across the country.

After selecting a U.S. metropolitan area and entering the number of EVs in the light-duty fleet, users can change a range of variables to see how they affect electricity demand on a typical weekday or weekend. Reducing access to home charging by half, for example, results in higher electric loads earlier in the day, although energy storage and mobile charging can help moderate peaks in some cases. That is because under such a scenario, EV owners might rely more on public or workplace charging instead of plugging in at home later in the evening or at night.

“Our goal with the lite version of EVI-Pro is to make estimating loads across thousands of scenarios fast and intuitive,” Wood said. “And if utilities or stakeholders want to take that analysis even deeper, our team at NREL can fill that gap through partnership agreements, too. The full version of EVI-Pro can be tailored to develop detailed studies for individual planners, agencies, or utilities.”

These companies are using oceans and rivers to generate electricity

Tidal Energy harnesses ocean currents with tidal turbines to deliver predictable, renewable power. From Scotland's Orkney to New York's East River, clean baseload electricity complements wind and solar in decarbonizing grids.

 

Key Points

Tidal energy uses underwater turbines to capture predictable ocean currents, delivering reliable, low-carbon power.

✅ Predictable 2-way flows enable forecastable baseload

✅ Higher energy density than wind, slower flow speeds

✅ Costs remain high; scaling and deployment are challenging

 

As the world looks to curb climate change and reduce fossil fuel emissions, some companies are focusing on a relatively untapped but vast and abundant source of energy — tidal waves.

On opposite sides of the Atlantic, two firms are working to harness ocean currents in different ways to try to generate reliable clean energy.

Off the coast of Scotland, Orbital Marine Power operates what it says is the "most powerful tidal turbine in the world." The turbine is approximately the size of a passenger airplane and even looks similar, with its central platform floating on the water and two wings extending downwards on either side. At the ends of each wing, about 60 feet below the surface, are large rotors whose movement is dictated by the waves.

"The energy itself of tidal streams is familiar to people, it's kinetic energy, so it's not too dissimilar to something like wind," Andrew Scott, Orbital's CEO, told CNN Business. "The bits of technology that generate power look not too different to a wind turbine."

But there are some key differences to wind energy, primarily that waves are far more predictable than winds. The ebb and flow of tides rarely differs significantly and can be timed far more precisely.

Orbital Marine Power's floating turbines off the Scottish coast produce enough energy to power 2,000 homes a year, while another Scottish tidal project recently produced enough for nearly 4,000 homes.

Orbital Marine Power's floating turbines off the Scottish coast produce enough energy to power 2,000 homes a year.

"You can predict those motions years and decades [in] advance," Scott said. "But also from a direction perspective, they only really come from two directions and they're almost 180 degrees," he added, unlike wind turbines that must account for wind from several different directions at once.

Tidal waves are also capable of generating more energy than wind, Scott says.

"Seawater is 800 times the density of wind," he said. "So the flow speeds are far slower, but they generate far more energy."

The Orbital turbine, which is connected to the electricity grid in Scotland's Orkney, can produce up to two megawatts — enough to power 2,000 homes a year — according to the company.

Scott acknowledges that the technology isn't fully mainstream yet and some challenges remain including the high cost of the technology, but the reliability and potential of tidal energy could make it a useful tool in the fight against climate change, as projects like Sustainable Marine in Nova Scotia begin delivering power to the grid.

"It is becoming increasingly apparent that ... climate change is not going to be solved with one silver bullet," he said.


'Could be 24/7 power'
Around 3,000 miles away from Orbital's turbines, Verdant Power is using similar technology to generate power near Roosevelt Island in New York City's East River. Although not on the market yet, Verdant's turbines set up as part of a pilot project help supply electricity to New York's grid. But rather than float near the surface, they're mounted on a frame that's lowered to the bottom of the river.

"The best way to envision what Verdant Power's technology is, is to think of wind turbines underwater," the company's founder, Trey Taylor, told CNN Business. And river currents tend to provide the same advantages for energy generation as ocean currents, he explained (though the East River is also connected to the Atlantic).

"What's nice about our rivers and systems is that could be 24/7 power," he said, even as U.S. offshore wind aims to compete with gas. "Not to ding wind or solar, but the wind doesn't always blow and the sun doesn't always shine. But river currents, depending on the river, could be 24/7."

Verdant Power helps supply electricity to New York City
Over the course of eight months, Verdant has generated enough electricity to power roughly 60 homes — though Taylor says a full-fledged power plant built on its technology could generate enough for 6,000 homes. And by his estimate, the global capacity for tidal energy is enormous, with regions like the Bay of Fundy pursuing new attempts around Nova Scotia.


A costly technology
The biggest obstacle to reaching that goal at the moment is how expensive it is to set up and scale up tidal power systems.

"Generating electricity from ocean waves is not the challenge, the challenge is doing it in a cost-effective way that people are willing to pay for that competes with ... other sources of energy," said Jesse Roberts, Environmental Analysis Lead at the US government-affiliated Sandia National Laboratories. "The added cost of going out into the ocean and deploying in the ocean... that's very expensive to do," he added. According to 2019 figures from the US Department of Energy, the average commercial tidal energy project costs as much as $280 per megawatt hour. Wind energy, by comparison, currently costs roughly $20 per megawatt hour and is "one of the lowest-priced energy sources available today," with major additions like the UK's biggest offshore wind farm starting to supply the grid, according to the agency.

When operational, the Orbital turbine's wing blades drop below the surface of the water and generate power from ocean currents.

When operational, the Orbital turbine's wing blades drop below the surface of the water and generate power from ocean currents.

Roberts estimates that tidal energy is two or three decades behind wind energy in terms of adoption and scale.

The costs and challenges of operating underwater are something both Scott and Taylor acknowledge.
"Solar and wind are above ground. It's easy to work with stuff that you can see," Taylor said. "We're underwater, and it's probably easier to get a rocket to the moon than to get these to work underwater."
But the goal of tidal power is not so much to compete with those two energy sources as it is to grow the overall pie, alongside innovations such as gravity power that can help decarbonize grids.

"The low hanging fruit of solar and wind were quite obvious," Scott said. "But do they have to be the only solution? Is there room for other solutions? I think when the energy source is there, and you can develop technologies that can harness it, then absolutely."

Europe's Green Surge: Renewables Soar, Emissions Plummet, but Challenges Remain

EU Renewable Energy Transition accelerates wind and solar growth, slashes fossil fuels and carbon emissions via the ETS, strengthens energy security with LNG diversification, and advances grid resilience toward 2030 climate targets.

 

Key Points

EU shift to wind, solar, and efficiency that cuts fossil fuels while boosting energy security and grid stability

✅ Fossil fuels at 29% of EU power in 2023, coal and gas down sharply

✅ Renewables hit 44% share; wind 18%, solar 9% and rising

✅ ETS, LNG diversification, and efficiency cut demand and emissions

 

Europe's energy landscape is undergoing a dramatic transformation, fueled by a surge in renewable energy and a corresponding decline in fossil fuel dependence. This shift, documented in both a report from the energy think tank Ember and the European Commission's State of the Energy Union report, paints a picture of progress, but also highlights the challenges that lie ahead on the path to a sustainable future.

 

Fossil Fuels Facing an Unprecedented Decline:

Fossil fuels dipped to their lowest point in recorded history, making up only 29% of EU electricity generation in 2023. This represents a significant 19% decrease in both fossil fuel generation and carbon emissions compared to 2022, exceeding even the reductions witnessed during the pandemic. Coal, the dirtiest fossil fuel, saw the steepest decline, dropping by 26%, while gas generation fell by 15%. This decline is attributed to a combination of factors, including:

Increased deployment of renewables: As renewable energy sources like wind and solar become more affordable and efficient, they are increasingly displacing fossil fuels in the energy mix.

Carbon pricing: The EU's Emissions Trading System (ETS) puts a price on carbon emissions, incentivizing generators to switch to cleaner sources of energy.

Geopolitical tensions: The war in Ukraine and subsequent sanctions on Russia have accelerated Europe's efforts to diversify its energy sources away from Russian fossil fuels across the bloc.


Renewables Ascending to New Heights:

Renewable energy is now the dominant force in the EU, as renewables surpassed fossil fuels in the power mix, contributing a record-breaking 44% of the electricity mix. Wind energy leads the charge, generating 18% of electricity – the equivalent of France's entire demand – and surpassing gas for the first time. Solar power also continues to grow, reaching a 9% share, as solar reshapes electricity prices in Northern Europe and hydropower recovered from its 2022 dry spell. This remarkable growth is driven by factors such as:

Favorable policy frameworks: The EU has set ambitious renewable energy targets and implemented supportive policies, including feed-in tariffs and auctions.

Technological advancements: Advancements in wind turbine and solar panel technologies have made them more efficient and cost-effective.
Public support: There is growing public support for renewable energy, driven by concerns about climate change and energy security.

Beyond generation, energy efficiency is playing a critical role in reducing overall energy demand. Electricity demand in the EU fell by 3.4% in 2023, thanks to factors such as improved building insulation and more efficient appliances.

 

EU on Track to Quit Russian Fossil Fuels:

The report underscores Europe's progress in reducing dependence on Russian fossil fuels. Imports of Russian gas have plummeted to 40-45 billion cubic metres, compared to a staggering 155 bcm in 2021. This represents a remarkable 70% reduction in just one year. This shift has been achieved through a combination of increased LNG imports, diversification of gas suppliers, and accelerated deployment of renewable energy sources.

Overall greenhouse gas emissions decreased by 3% in 2022, putting the EU on track to achieve its ambitious 55% reduction target by 2030. These achievements demonstrate the EU's commitment to climate action and its ability to respond decisively to geopolitical challenges.

 

Success, But Not Complacency:

Despite the positive developments, the Commission warns against complacency. Energy markets remain volatile, fossil fuel subsidies are rising in some countries, and critical infrastructure vulnerabilities persist, while some advocates call for a fossil fuel lockdown to accelerate the transition. The bloc needs to accelerate renewable energy expansion to reach the legally binding 42.5% target by 2030. Additionally, ensuring affordability and security of energy supply will be crucial to maintaining public support for the transition.

 

Challenges and Opportunities:

While some countries like Denmark, Finland, and the Netherlands fall short of EU climate and energy goals, others like Spain, Portugal, and Belgium showcase success with renewables. The Commission is taking action with a plan to support the wind industry, where investments in European wind continue, even as it faces challenges from high inflation and increasing competition from China. Additionally, ensuring timely updates to national energy and climate plans is crucial for achieving the EU's overall objectives.

 

NGOs Urge Faster Action:

NGOs like the Climate Action Network (CAN) express concern about the adequacy of national plans, highlighting the gap between ambition and concrete action. They urge member states to accelerate efforts to meet the 2030 targets and avoid a "lost decade" in climate action. CAN emphasizes the need for more ambitious national energy and climate plans, increased investment in renewables, and accelerated energy efficiency measures.

Europe's energy transition is progressing rapidly, with renewables taking center stage and emissions declining. However, significant challenges remain, necessitating continued commitment, national-level action, and a focus on affordability, security, and sustainability. As 2030 approaches, Europe's green surge must translate into concrete results to secure a climate-neutral future.

 

Looking ahead, several key areas will define the success of Europe's energy transition:

  • Accelerating renewable energy deployment: The EU needs to maintain its momentum in building wind, solar, and other renewable energy sources. This requires sustained clean energy investment, streamlined permitting processes, and addressing grid integration challenges.
  • Ensuring affordability and security of supply: The energy transition must be just and inclusive, ensuring that energy remains affordable for all citizens and businesses. Additionally, diversifying energy sources and enhancing grid resilience are crucial to guarantee energy security.
  • Enhancing energy efficiency: Reducing energy demand remains crucial to achieving climate goals and reducing reliance on fossil fuels. This requires continued investments in building energy efficiency, promoting energy-efficient appliances and technologies, and encouraging behavioral changes.
  • International cooperation: Climate change and energy security are global challenges. The EU must continue to lead by example as renewables exceed 30% globally and collaborate with other countries on technological advancements, policy innovations, and financial support for developing nations undergoing their own energy transitions.

Europe's green surge is a testament to its ambition and collective action. By addressing the remaining challenges and seizing the opportunities ahead, the EU can pave the way for a sustainable and secure energy future for itself and the world.
