On the outskirts of Seville, Spain, 600 rotating mirrors send shafts of light to a collector atop a soaring 115-meter-tall tower.

Its scalding 250-degree-Celsius steam drives a turbine generating a peak capacity of 11 megawatts (MW) of electricity for the national grid. This "power tower" is the first of nine to be built by Spanish engineering giant Abengoa Solar, which all told will produce enough electricity for 153,000 homes by 2013.

From power towers to parabolic trough plants and from photovoltaic farms to roof-mounted solar panels, solar energy is booming in Spain. This month, Europe's first commercial solar-thermal parabolic trough plant — 24-kilometer curved mirror complex dubbed Andasol that focuses light on collector tubes with synthetic oil bubbling to 400 degrees C — revs up in Andalusia. Vast acres of solar farms using photovoltaics made from semiconductors to convert sunlight to electricity now span southern Spain.

Celebrated ground-mounted photovoltaic (PV) plants include La Magascona and Jumilla with their array of 120,000 modules on 120 single-axis "follow-the-sun" trackers.

Even carmakers want a piece of the Spanish sun. In July General Motors said it will build the world's biggest rooftop solar power station in Spain, carpeting 185,800 square meters of the roof at its Zaragoza automobile plant with 85,000 flexible solar panels. And the 50-megawatt Andasol plant is also the world's largest facility employing molten salts to store renewable energy: 28,500 tons of molten potassium and sodium nitrate salt in two tanks that bank excess solar heat for more than seven hours.

Plentiful sunshine isn't the only reason entrepreneurs and industry have flocked to Spain.

The Spanish advantage includes abundant land, strong demand for air conditioning, mammoth infrastructural firms to fast-track projects, and, most importantly, generous subsidies. The nation's feed-in tariffs guarantee 25 years of up to triple the market price for solar energy, making it the world's hottest solar market, trailing only subsidy-richer Germany as well as the U.S. with its historical lead in developing solar technology.

"Feed-in tariffs shift competition to manufacturers, creating an incentive for innovation," says Wilson Rickerson, a Boston-based energy consultant. "Manufacturers that can produce the most efficient and cost-effective ways of generating energy gain most."

In fact, money committed for Spanish PV projects (mostly ground-based) shot up nearly 500 percent from 2006 to 2007 to a total of $3.45 billion, according to London-based New Energy Finance, a renewable energy market research firm.

But obscuring the light are a few clouds. This month Spain slashed the maximum capacity of solar farms that can claim subsidies from 1,200 MW to just 500 MW. Installed PV capacity has already tripled to 1,500 MW in under a year, should double again by 2010 to 3,000 MW, and more than triple to 10,000 MW by 2020. Spain also cut PV feed-in tariffs by about a third to around 33 eurocents per kilowatt hour. Solar-thermal executives fear the same fate within 24 months as new plants add solar power.

That's led many companies to mull other markets. Though Spain backpedaled on severe cuts after panel makers balked, companies like Energias de Portugal Renovables are pulling out because of profit worries and, in August, BP shelved plans for the world's largest solar panel plant in Spain. Critics have warned that when subsidies dry up, so will solar's appeal.

"PV project developers rushed to Spain because subsidies guaranteed returns well above the cost of generating power," explains Nathaniel Bullard, a solar associate at New Energy Finance. "Cuts will drive developers to other markets with high subsidies."

Companies are already eyeing the area's "Club Med" countries where similar feed-in tariffs exist, such as France, Greece and Italy; swathes of sunny Latin America are a possibility; and the U.S. is the ultimate objective as the world's largest electricity market with abundant potential in its sun-soaked Southwest. Healthy tax credits for solar energy in the U.S., extended for eight years in October are also a draw. Abengoa is already building the world's largest solar plant, 280-MW Solana, in Arizona.

"We've been in Spain since 1999 where 80 percent of our revenues originate because its south has double Germany's sunshine and attractive feed-in tariffs," says Henner Gladen, chief technology officer at solar-thermal firm Solar Millennium. That share should fall as the company's new U.S. projects gain ground. "And China, Australia, the Middle East and Africa are the markets of tomorrow."

Spain is already charging into North Africa, which is bathed in 40 percent more sunlight. With World Bank backing, Abengoa is breaking ground on the first hybrid solar-thermal and natural gas burning power plants in Morocco and Algeria, online by 2010. "With abundant radiation and land in its deserts, our neighbor, North Africa, is this region's Southwest," says Michael Geyer, director of international business development at Abengoa, noting that Algeria already has feed-in tariffs. Solar-thermal plants are also planned for Egypt, Israel, Jordan, Libya and the United Arab Emirates.

Most importantly, the initial African power plants and Spain's solar-thermal test bed pave the way for energy export from planned solar farms in the Sahara Desert across a high-voltage direct current trans-sea line to Europe, pending political will and public funds. French President Nicolas Sarkozy resurrected the idea this year in a Plan Solaire.

Studies show that harnessing just 0.3 percent of the sunshine on North African and Middle Eastern deserts could power those regions and Europe. Optimists, such as Nikolai Ulrich, head of renewables Europe at Germany's Nordbank, foresee energy export from Africa within seven years. Imminent milestones include talks in Algeria and Tunisia for transmission lines to Italy, planned for next year. Spain has an edge, because it has been swapping electricity with Morocco over their own two-way line for about a dozen years.

And Spain's solar revolution at home may only slow — not stall. Spain has ample sun, legislation that calls for solar on all new buildings, and PVs poised to deliver low-cost electricity. "Spain is a leader in CSP [concentrated solar power] and hybrid solar/natural gas systems," says Paolo Frankl, head of renewable energy at the International Energy Agency. "And in Spain I expect a shift from ground-mounted plants to solar installations in industrial sites, buildings and other infrastructure like highways. Competition helps innovation."

There's a Russia-Sized Mystery in China's Electricity Sector

China Power Demand-Emissions Gap highlights surging grid demand outpacing renewables, with coal filling shortages despite record solar, wind, EV charging, and hydrogen growth, threatening decarbonization targets and net-zero pathways through 2030.

 

Key Points

China's power demand outpaces renewables, keeping coal dominant and raising emissions risk through the 2020s.

✅ Record solar and wind still lag fast grid demand growth

✅ Coal fills gaps as EV charging and hydrogen loads rise

✅ Forecasts diverge: CEC bullish vs IEA, BNEF conservative

 

Here’s a new obstacle that could prevent the world finally turning the corner on climate change: Imagine that over the coming decade a whole new economy the size of Russia were to pop up out of nowhere. With the world’s fourth-largest electricity sector and largest burden of power plant emissions after China, the U.S. and India, this new economy on its own would be enough to throw out efforts to halt global warming — especially if it keeps on growing through the 2030s.

That’s the risk inherent in China’s seemingly insatiable appetite for grid power, as surging electricity demand is putting systems under strain worldwide.

From the cracking pace of renewable build-out last year, you might think the country had broken the back of its carbon addiction. A record 55 gigawatts of solar power and 48 gigawatts of wind were connected — comparable to installing the generation capacity of Mexico in less than 12 months. This year will see an even faster pace, with 93 GW of solar and 50 GW of wind added, according to a report last week from the China Electricity Council, an industry association.

That progress could in theory see the country’s power sector emissions peak within months, rather than the late-2020s date the government has hinted at. Combined with a smaller quantity of hydro and nuclear, low-emissions sources will probably add about 310 terawatt-hours to zero-carbon generation this year. That 3.8% increase would be sufficient to power the U.K.

Countries that have reached China’s levels of per-capita electricity consumption (already on a par with most of Europe) typically see growth rates at less than half that level, even as global power demand has surged past pre-pandemic levels in recent years. Grid supply could grow at a faster pace than Brazil, Iran, South Korea or Thailand managed over the past decade without adding a ton of additional carbon to the atmosphere.

There’s a problem with that picture, however. If electricity demand grows at an even more headlong pace, there simply won’t be enough renewables to supply the grid. Fossil fuels, overwhelmingly coal, will fill the gap, a reminder of the iron law of climate dynamics in energy transitions.

Such an outcome looks distinctly possible. Electricity consumption in 2021 grew at an extraordinary rate of 10%, and will increase again by between 5% and 6% this year, according to the CEC. That suggests the country is on pace to match the CEC’s forecasts of bullish grid demand over the coming decade, with generation hitting 11,300 terawatt-hours in 2030. External analysts, such as the International Energy Agency and BloombergNEF, envisage a more modest growth to around 10,000 TWh. 

The difference between those two outlooks is vast — equivalent to all the electricity produced by Russia or Japan. If the CEC is right and the IEA and BloombergNEF are wrong, even the furious rate of renewable installations we’re seeing now won’t be enough to rein in China’s power-sector emissions.

Who’s correct? On one hand, it’s fair to say that power planners usually err on the side of overestimation. If your forecast for electricity demand is too high, state-owned generators will be less profitable than they otherwise would have been — but if it’s too low, you’ll see power cuts and shutdowns like China witnessed last autumn, with resulting power woes affecting supply chains beyond its borders.

On the other hand, the decarbonization of China’s economy itself should drive electricity demand well above what we’ve seen in the past, with some projections such as electricity meeting 60% of energy use by 2060 pointing to a profound shift. Some 3.3 million electric vehicles were sold in 2021 and BloombergNEF estimates a further 5.7 million will be bought in 2022. Every million EVs will likely add in the region of 2 TWh of load to the grid. Those sums quickly mounts up in a country where electric drivetrains are taking over a market that shifts more than 25 million new cars a year.

Decarbonizing industry, a key element on China’s road to zero emissions, could also change the picture. The IEA sees the country building 25 GW of electolysers to produce hydrogen by 2030, enough to consume some 200 TWh on their own if run close to full-time.

That’s still not enough to justify the scale of demand being forecast, though. China is already one of the least efficient countries in the world when it comes to translating energy into economic growth, and despite official pressure on the most wasteful, so called “dual-high” industries such as steel, oil refining, glass and cement, its targets for more thrifty energy usage remain pedestrian.

The countries that have decarbonized fastest are those, such as Germany, the U.K and the U.S., where Americans are using less electricity, that have seen power demand plateau or even decline, giving new renewable power a chance to swap out fossil-fired generators without chasing an ever-increasing burden on the grid. China’s inability to do this as its population peaks and energy consumption hits developed-country levels isn’t a sign of strength.

Instead, it’s a sign of a country that’s chronically unable to make the transition away from polluting heavy industry and toward the common prosperity and ecological civilization that its president keeps promising. Until China reins in that credit-fueled development model, the risks to its economy and the global climate will only increase.

Wartsila to Power USA’s First Battery-Electric High-Speed Ferries

San Francisco Battery-Electric Ferries will deliver zero-emission, high-speed passenger service powered by Wartsila electric propulsion, EPMS, IAS, batteries, and shore power, advancing maritime decarbonization under the REEF program and USCG Subchapter T standards.

 

Key Points

They are the first US zero-emission high-speed passenger ferries using integrated electric propulsion and shore power

✅ Dual 625 kW motors enable up to 24-knot service speeds

✅ EPMS, IAS, DC hub, and shore power streamline operations

✅ Built to USCG Subchapter T for safety and compliance

 

Wartsila, a global leader in sustainable marine technology, has been selected to supply the electric propulsion system for the United States' first fully battery-electric, zero-emission high-speed passenger ferries. This significant development marks a pivotal step in the decarbonization of maritime transport, aligning with California's ambitious environmental goals, including recent clean-transport investments across ports and corridors.

A Leap Toward Sustainable Maritime Transport

The project, commissioned by All American Marine (AAM) on behalf of San Francisco Bay Ferry, involves the construction of three 150-passenger ferries, reflecting broader U.S. advances like the Washington State Ferries hybrid upgrade now underway. These vessels will operate on new routes connecting the rapidly developing neighborhoods of Treasure Island and Mission Bay to downtown San Francisco. The ferries are part of the Rapid Electric Emission Free (REEF) Ferry Program, a comprehensive initiative by San Francisco Bay Ferry to transition its fleet to zero-emission propulsion technology. The first vessel is expected to join the fleet in early 2027.

Wärtsilä’s Role in the Project

Wärtsilä's involvement encompasses the supply of a comprehensive electric propulsion system, including the Energy and Power Management System (EPMS), integrated automation system (IAS), batteries, DC hub, transformers, electric motors, and shore power supply. This extensive scope underscores Wärtsilä’s expertise in providing integrated solutions for emission-free marine transportation. The company's extensive global experience in developing and supplying integrated systems and solutions for zero-emission high-speed vessels, as seen with electric ships on the B.C. coast operating today, was a key consideration in the selection process.

Technical Specifications of the Ferries

The ferries will be 100 feet (approximately 30 meters) in length, with a beam of 26 feet and a draft of 5.9 feet. Each vessel will be powered by dual 625-kilowatt electric motors, enabling them to achieve speeds of up to 24 knots. The vessels will be built to U.S. Coast Guard Subchapter T standards, ensuring compliance with stringent safety regulations.

Environmental and Operational Benefits

The transition to battery-electric propulsion offers numerous environmental and operational advantages. Electric ferries produce zero emissions during operation, as demonstrated by Berlin's electric ferry deployments, significantly reducing the carbon footprint of maritime transport. Additionally, electric propulsion systems are generally more efficient and require less maintenance compared to traditional diesel engines, leading to lower operational costs over the vessel's lifespan.

Broader Implications for Maritime Decarbonization

This project is part of a broader movement toward sustainable maritime transport in the United States. San Francisco Bay Ferry has also approved the purchase of two larger 400-passenger battery-electric ferries for transbay routes, further expanding its commitment to zero-emission operations. The agency has secured approximately $200 million in funding from local, state, and federal sources, echoing infrastructure bank support seen in B.C., to support these initiatives, including vessel construction and terminal electrification.

Wartsila’s involvement in this project highlights the company's leadership in the maritime industry's transition to sustainable energy solutions, including hybrid-electric pathways like BC Ferries' new hybrids now in service. With a proven track record in supplying integrated systems for zero-emission vessels, Wärtsilä is well-positioned to support the global shift toward decarbonized maritime transport.

As the first fully battery-electric high-speed passenger ferries in the United States, these vessels represent a significant milestone in the journey toward sustainable and environmentally responsible maritime transportation, paralleling regional advances such as the Kootenay Lake electric-ready ferry entering service. The collaboration between Wärtsilä, All American Marine, and San Francisco Bay Ferry exemplifies the collective effort required to realize a zero-emission future for the maritime industry.

The deployment of these battery-electric ferries in San Francisco Bay not only advances the city's environmental objectives but also sets a precedent for other regions to follow. With continued innovation and collaboration, the maritime industry can look forward to a future where sustainable practices are the standard, not the exception.

U.S. residential electricity bills increased 5% in 2022, after adjusting for inflation

U.S. Residential Electricity Bills rose on stronger demand, inflation, and fuel costs, with higher retail prices, kWh consumption, and extreme weather driving 2022 spikes; forecasts point to stable summer usage and slight price increases.

 

Key Points

They are average household power costs shaped by prices, kWh use, weather, and upstream fuel costs.

✅ 2022 bills up 13% nominal, 5% real vs. 2021

✅ Retail price rose 11%; consumption up 2% to 907 kWh

✅ Fuel costs to plants up 34%, pressuring rates

 

In nominal terms, the average monthly electricity bill for residential customers in the United States increased 13% from 2021 to 2022, rising from $121 a month to $137 a month. After adjusting for inflation—which reached 8% in 2022, a 40-year high—electricity bills increased 5%. Last year had the largest annual increase in average residential electricity spending since we began calculating it in 1984. The increase was driven by a combination of more extreme temperatures, which increased U.S. consumption of electricity for both heating and cooling, and higher fuel costs for power plants, which drove up retail electricity prices nationwide.

Residential electricity customers’ monthly electricity bills are based on the amount of electricity consumed and the retail electricity price. Average U.S. monthly electricity consumption per residential customer increased from 886 kilowatthours (kWh) in 2021 to 907 kWh in 2022, even as U.S. electricity sales have declined over the past seven years. Both a colder winter and a hotter summer contributed to the 2% increase in average monthly electricity consumption per residential customer in 2022 because customers used more space heating during the winter and more air conditioning during the summer, with some states, such as Pennsylvania, facing sharp winter rate increases.

Although we don’t directly collect retail electricity prices, we do collect revenues from electricity providers that allow us to determine prices by dividing by consumption, and industry reports show major utilities spending more on electricity delivery than on power production. In 2022, the average U.S. residential retail electricity price was 15.12 cents/kWh, an 11% increase from 13.66 cents/kWh in 2021. After adjusting for inflation, U.S. residential electricity prices went up by 2.5%.

Higher fuel costs for power plants drove the increase in residential retail electricity prices. The cost of fossil fuels—including natural gas prices, coal, and petroleum—delivered to U.S. power plants increased 34%, from $3.82 per million British thermal units (MMBtu) in 2021 to $5.13/MMBtu in 2022. The higher fuel costs were passed along to residential customers and contributed to higher retail electricity prices, and Germany power prices nearly doubled over a year in a related trend.

In the first three months of 2023, the average U.S. residential monthly electricity bill was $133, or 5% higher than for the same time last year, according to data from our Electric Power Monthly. The increase was driven by a 13% increase in the average U.S. residential retail electricity price, which was partly offset by a 7% decrease in average monthly electricity consumption per residential customer, and industry outlooks also see U.S. power demand sliding 1% on milder weather. This summer, we expect that typical household electricity bills will be similar to last year’s, with customers paying about 2% more on average. The slight increase in electricity costs forecast for this summer stems from higher retail electricity prices but similar consumption levels as last summer.

4 ways the energy crisis hits U.S. electricity, gas, EVs

U.S. Energy Crunch disrupts fuel and power markets, driving natural gas price spikes, coal resurgence, utility mix shifts, supply chain strains for EV batteries, and inflation pressures, complicating climate policy, OPEC outreach and LNG trade

 

Key Points

Supply-demand gaps raise fuel costs, revive coal, strain EV materials, and complicate U.S. climate policy and plans.

✅ Natural gas spikes shift generation from gas to coal

✅ Supply chain shortages hit nickel, silicon, and chips

✅ Policy tensions between price relief and decarbonization

 

A global energy crunch is creating pain for people struggling to fill their tanks and heat their homes, as well as roiling the utility industry’s plans to change its mix of generation and complicating the Biden administration’s plans to tackle climate change.

The ripple effects of a surge in natural gas prices include a spike in coal use and emissions that counter clean energy targets. High fossil fuel prices also are translating into high prices and a supply crunch for key minerals like silicon used in clean energy projects. On a call with investors yesterday, a Tesla Inc. executive said the company is having a hard time finding enough nickel for batteries.

The crisis could pose political problems for the Biden administration, which spent the last few months fending off criticism about rising fuel prices and inflation (Energywire, Oct. 14).

“Energy issues at this moment are as salient to the American public as they have been in quite some time,” said Christopher Borick, who directs the Muhlenberg College Institute of Public Opinion in Pennsylvania, where Biden stopped yesterday to pitch his infrastructure plan.

While gasoline prices have gotten headlines all summer, natural gas prices have risen faster than motor fuels, more than doubling from an average $1.92 per thousand cubic feet in September 2020 to $5.16 last month. By comparison, gasoline prices have risen about 55 percent in the last year, to $3.36 per gallon nationwide this week, according to AAA.

The roots of the problem go back to the beginning of the pandemic and the recession in 2020. Oil and gas prices fell so fast then that many producers, particularly in the U.S., simply stopped drilling.

Oil companies began predicting a few months later that the abrupt shutdown would eventually lead to shortages and price spikes when the economy recovered. Those predictions turned out to be accurate.

With the economy beginning to recover, demand for gas has gone up, but there’s not enough supply to go around.

While the U.S. energy crunch isn’t as severe as Europe’s energy crisis today, and analysts predict that gas prices will gradually fall next year, consumers could be in for a rough couple of months.

Here’s four ways the global energy crisis is impacting the United States, from the electricity sector to the political landscape:

What are the political repercussions?
For the Biden administration, the energy price hikes come amid fears of rising inflation and persistent supply bottlenecks at the nation’s ports as its climate ambitions face headwinds in Congress.

“The confluence of energy prices, logistical challenges and the need to move on climate have raised this to the top tier,” said Borick, who in the past has polled on energy and environmental issues in Pennsylvania.

Borick noted the administration is facing counterpressures: Even as it pushes to decarbonize the nation’s electric system, it wants to keep gas prices in check. High gasoline prices have been linked to declining political approval ratings, including for presidents, even if much of the price hikes are beyond their control.

White House press secretary Jen Psaki said earlier this month that the administration can take steps to address what it called “short-term supply issues,” but also needs to focus on the long term — and climate.

In hopes of capping prices, the White House has spoken with members of OPEC about increasing oil production — though OPEC has little control over natural gas prices. And earlier this month, the administration talked to U.S. oil and gas producers about helping to bring down prices.

That comes even as environmentalists have pushed Biden to ban federal fossil fuel leasing and drilling and stop new projects.

The moves to curb prices have prompted ridicule from Republicans, who have accused Biden of declaring war on U.S. energy by canceling the Keystone XL pipeline.

“The Biden administration won’t say it out loud, yet let’s admit it: There is a crisis,” Sen. John Barrasso (R-Wyo.) said this week on the Senate floor. “It is one that Joe Biden and his administration has created. It is a crisis of Joe Biden’s own making.”

The situation has also resurfaced comparisons to former President Carter, who struggled politically in the 1970s with gasoline shortages and other energy pressures. Some political scientists say, though, the comparison between the two isn’t apples to apples.

"In 1979, the crisis began with the Iranian Revolution, producing a supply shortage. In the USA, some states rationed the supply. That’s not occurring now. Oil prices were also regulated, another difference, “ said Terry Madonna, a senior fellow in residence for political affairs at Millersville University.

A Morning Consult poll released yesterday carried warning signs for Democrats with worries about the economy on the rise across the political spectrum.

Voters, however, were evenly split on how Biden is handling energy. Forty-two percent of respondents approve of Biden’s energy policy, compared with 45 percent who disapproved. The margin of error is 2 percentage points.

Will the electricity mix change?
Higher gas prices are giving coal a boost in some markets.

Atlanta-based Southern Co. told CNBC earlier this week, for instance, that coal was about 17 percent of the company’s power mix last year. That has changed in 2021.

“The unintended consequence of high gas prices is that coal becomes more economic, and so my sense is … our coal production has bumped up above 20 percent,” Southern CEO Tom Fanning said. “Now, how long that’ll persist, I don’t know.”

Fanning said “what we’re seeing right now, and the real challenge in America, is this notion of energy in transition.”

But the U.S. power sector has been evolving for years, with more renewables and less coal on the grid, and experts say the current energy crunch won’t change long-term utility trends in the industry.

“In general, I wouldn’t place too much emphasis on short-term fluctuations,” Jay Apt, a professor at Carnegie Mellon University, said in an email. “There is still a robust supply chain for most components needed for low-pollution power, including renewables.”

In fact, elevated fossil fuel prices, and high natural gas prices in particular, could accelerate the move toward wind, solar and batteries in some areas. That’s because power plants that run on coal and natural gas can be affected by rising and volatile fuel prices, as illustrated by the recent move in commodities globally. That means higher costs to run the facilities, even if power prices often climb along with gas prices.

“If I were a utility planner, this would cause me to double down on new generation from [wind] and solar and storage as opposed to building additional natural gas plants where, you know, I could be having these super high and volatile operating costs,” said Bri-Mathias Hodge, an associate professor in the Department of Electrical, Computer and Energy Engineering at the University of Colorado, Boulder.

Ed Hirs, an energy fellow at the University of Houston, said the current global situation doesn’t change the U.S. power sector’s overall move toward generation with lower operating costs.

For example, he said nuclear and coal plants can require hundreds of employees, and both have fuel costs. Hirs said a gas facility also needs fuel and may need dozens of employees. Wind and solar facilities often need a smaller number of workers and don’t require fuel in their operations, he noted.

“Eventually the cheap wins out,” Hirs said.

That isn’t even factoring in climate change — the reason world leaders are seeking to slash greenhouse gas emissions. Indeed, lowering emissions remains a priority among many states and big companies in the U.S.

Over the next 10 to 15 years, Hirs said, a key question will be whether battery technology can compete economically in terms of backing up renewables. He said a national carbon price, if enacted, would aid renewables and enhance returns on batteries.

“The real battle is going to be between natural gas and battery storage,” Hirs said.

Apt and M. Granger Morgan, who’s also a Carnegie Mellon professor, noted in a Hill piece last month that the U.S. gets about 40 percent of its power from carbon-free sources, including nuclear.

“Modelers and many power system operators agree that it is possible that renewables can cost-effectively make up roughly 80% of electricity generation,” the professors wrote, adding that other sources could include “storage and gas turbines powered with hydrogen, synfuels, or natural gas with carbon capture.”

What about EVs and renewables?
As for electric vehicles, executives with Tesla said on a call yesterday that supply-chain problems are the major brake on production for both vehicles and batteries.

Chief Financial Officer Zachary Kirkhorn said that the company’s factories aren’t running at full capacity because of an ongoing shortage of semiconductor chips. Customers are waiting longer for vehicles, he said, and wait lists are growing.

The challenges extend to raw materials. In batteries, Kirkhorn said, the company is having trouble finding enough nickel, and in vehicles, it is scrounging for aluminum. He said the problem is "not small," and that prices may rise as supply contracts come up for renewal.

The supply problems are creating "cost headwinds," he said, and so are rising labor costs. Tesla is not immune from the worker shortages that are plaguing the entire U.S. economy.

The production woes aren’t limited to Tesla: Automakers around the world have have had their output crimped by the chip shortage that accompanied the economic rebound after pandemic lockdowns. Unlike many other automakers, Tesla hasn’t been forced to pause its factory lines.

Tesla said it is poised to greatly expand its production of batteries for the electric grid — with a caveat.

Last month, Tesla broke ground on a new California factory to make Megapack, its 3 megawatt-per-hour lithium-ion batteries for use by power companies. That future factory’s capacity, 40 gigawatt per hour a year, is vastly more than the 3 GWh it made in the last calendar year.

However, today’s supply-chain problems are braking the making of both Megapack and Powerwall, Tesla’s battery for homes, Kirkhorn said. He added that production will increase "as soon as parts allow us."

Other advocates for EVs and renewable power expressed little concern about the supply crunch’s meaning for their industries, noting that higher prices alone don’t automatically trigger a broader green revolution on their own.

Those problems likely wouldn’t change the immediate course of the energy transition, researchers said.

"Short-term trends, week to week or even month to month, don’t matter much for investors or policy makers," wrote John Graham, a former budget official with the Bush administration and professor at Indiana University’s O’Neill School of Public and Environmental Affairs, in an email to E&E News.

The crunch may give policymakers a glimpse of the future, however, according to one minerals analyst.

"This isn’t going to be an outlier. I think increasingly you’re going to see pockets of the world start to feel these strains," said Andrew Miller, product director at Benchmark Mineral Intelligence, which focuses its research on battery minerals and battery supply chains.

The U.S. and its allies are only now beginning to develop their own supply chains for batteries and other key clean energy technologies, he noted. "The issue you’re facing, and this is one coming over time, is to have the platform in place. You have to have the supply chain of raw materials," he said.

"I think you’re going to see the most turbulence over the coming decade. … It’s not going to be a smooth transition,” added Miller.

How long will gas prices stay high?
The gap between natural gas demand and supply has led to severe price spikes in Europe, where utilities and other gas buyers have to compete against China for cargoes of liquefied natural gas, according to a research note from IHS Markit Ltd.

Here in the U.S., the causes are the same, but the results aren’t as extreme. Less than 10 percent of domestic gas production is exported as LNG, so American customers don’t have to compete as much against overseas buyers.

Instead, gas-hungry sectors of the economy have run into another problem, IHS analyst Matthew Palmer said in an interview. Gas producers have been cautious about increasing their output, largely because of pressure from investors to limit their spending.

“That theme has really put a governor on production,” he said.

The disconnect will likely mean higher home gas bills and higher electric prices this winter, although deep freeze events or warm weather could disrupt the trend, he said. The U.S. Energy Information Administration is predicting that average heating bills for homes that use gas furnaces will rise 30 percent this winter.

This comes as U.S. gas supply remains high, according to a biennial assessment from the Potential Gas Committee, a group of volunteer geoscientists, engineers and other experts.

Including reserves, future gas supply in the U.S. stands at a record 3,863 trillion cubic feet, up 25 tcf from levels reported in 2019, the group said Tuesday at an event co-hosted with the American Gas Association.

Of that total, so-called technically recoverable resources — or those in the ground but not yet recovered — are 3,368 tcf, the PGC said, down less than 0.2 percent from the last assessment.

The amount of technically recoverable gas went relatively unchanged from year-end 2018 for several reasons, including a lack of company activity in exploration efforts last year due to COVID, said Alexei Milkov, the group’s executive director.

Another factor is that basins mature and shale plays “cannot increase in resources forever,” said Milkov, also a professor of geology and geological engineering at the Colorado School of Mines.

Still, Milkov added, “We cannot tell you right now if we are on a new plateau, or if we are going to start seeing more growth in gas resources again, right, because it’s a complex issue.”

The EIA predicts that gas production will increase and prices will begin to drop in 2022.

David Flaherty, CEO of the Republican polling firm Magellan Strategies in Colorado, said prices could particularly hit seniors. But he said he expected the energy crunch to ease in the U.S. well before the election.

“By early summer, this is likely to be behind us,” he said.

Ontario Energy Board Sets New Electricity Rate Plan Prices and Support Program Thresholds

OESP Eligibility 2024 updates Ontario electricity affordability: TOU, Tiered, Ultra-Low-Overnight price plans, online bill calculator, higher income thresholds, monthly credits for low-income households, and a winter disconnection ban for residential customers.

 

Key Points

Raises income thresholds and credits to help low-income Ontarians cut electricity costs and choose suitable price plans.

✅ TOU, Tiered, and ULO price plans with online bill calculator

✅ Income eligibility thresholds raised up to 35% on March 1, 2024

✅ Winter disconnection ban for residences: Nov 15, 2023 to Apr 30, 2024

 

Residential, small business and farm customers can choose their price plan, either Time-Of-Use (TOU), Tiered or the ultra-low overnight rates price plan available to many customers. The OEB has an online bill calculator to help customers who are considering a switch in price plans and monitoring changes for electricity consumers this year. 

The Government of Ontario announced on Friday, October 19, 2023, that it is raising the income eligibility thresholds that enable Ontarians to qualify for the Ontario Electricity Support Program (OESP) by up to 35 percent. OESP is part of Ontario’s energy affordability framework and other support for electric bills meant to reduce the cost of electricity for low-income households by applying a monthly credit directly on to electricity bills.. The higher income eligibility thresholds will begin on March 1, 2024.

The amount of OESP bill credit is determined by the number of people living in a home and the household’s combined income, and can help offset typical bill increases many customers experience. The current income thresholds cap income eligibility at $28,000 for one-person households and $52,000 for five-person households, and temporary measures like the off-peak price freeze have also influenced bills in recent periods.

The new income eligibility thresholds, which will be in effect beginning March 1, 2024, will allow many more families to access the program as rates are about to change across Ontario.

In addition, under the OEB’s winter disconnection ban, which follows the Nov. 1 rate increase, electricity distributors cannot disconnect residential customers for non-payment from November 15, 2023, to April 30, 2024.

New Mexico Governor to Sign 100% Clean Electricity Bill ‘As Quickly As Possible’

New Mexico Energy Transition Act advances zero-carbon electricity, mandating public utilities deliver carbon-free electricity by 2045, with renewable targets of 50 percent by 2030 and 80 percent by 2040 to accelerate grid decarbonization.

 

Key Points

A state law requiring utilities to deliver carbon-free electricity by 2045, with 2030 and 2040 renewable targets.

✅ 100 percent carbon-free power from utilities by 2045

✅ Interim renewable targets: 50 percent by 2030, 80 percent by 2040

✅ Aligns with clean energy commitments in HI, CA, and DC

 

The New Mexico House of Representatives passed the Energy Transition Act Tuesday afternoon, sending the carbon-free electricity bill, a move aligned with proposals for a Clean Electricity Standard at the federal level, to Gov. Michelle Lujan Grisham.

Her opinions on it are known: she campaigned on raising the share of renewable energy, a priority echoed in many state renewable ambitions nationwide, and endorsed the ETA in a recent column.

"The governor will sign the bill as quickly as possible — we're hoping it is enrolled and engrossed and sent to her desk by Friday," spokesperson Tripp Stelnicki said in an email Tuesday afternoon.

Once signed, the legislation will commit the state to achieving zero-carbon electricity from public utilities by 2045. The bill also imposes interim renewable energy targets of 50 percent by 2030 and 80 percent by 2040, similar to Minnesota's 2040 carbon-free bill in its timeline.

The Senate passed the bill last week, 32-9. The House passed it 43-22.

The legislation would enter New Mexico into the company of Hawaii, California, where climate risks to grid reliability are shaping policy, and Washington, D.C., which have committed to eliminating carbon emissions from their grids. A dozen other states have proposed similar goals. Meanwhile, the Green New Deal resolution has prompted Congress to discuss the bigger task of decarbonizing the nation overall.

Though grid decarbonization has surged in the news cycle in recent months, even as some states consider moves in the opposite direction, such as a Wyoming bill restricting clean energy that would limit utility choices, New Mexico's bill arose from a years-long effort to rally stakeholders within the state's close-knit political community.
