Green carbon dioxide recycling emerging in B.C.

Attosecond Electron Transport uses ultrafast lasers and single-cycle light pulses to drive tunneling in bowtie gold nanoantennas, enabling sub-femtosecond switching in optoelectronic nanostructures and surpassing picosecond silicon limits for next-gen computing.

Key Points

A light-driven method that manipulates electrons with ultrafast pulses to switch currents within attoseconds.

✅ Uses single-cycle light pulses to drive electron tunneling

✅ Achieves 600 attosecond current switching in nano-gaps

✅ Enables optoelectronic, plasmonic devices beyond silicon

When it comes to data transfer and computing, the faster we can shift electrons and conduct electricity the better – and scientists have just been able to transport electrons at sub-femtosecond speeds (less than one quadrillionth of a second) in an experimental setup.

The trick is manipulating the electrons with light waves that are specially crafted and produced by an ultrafast laser. It might be a long while before this sort of setup makes it into your laptop, but similar precision is seen in noninvasive interventions where targeted electrical stimulation can boost short-term memory for limited periods, and the fact they pulled it off promises a significant step forward in terms of what we can expect from our devices.

Right now, the fastest electronic components can be switched on or off in picoseconds (trillionths of a second), a pace that intersects with debates over 5G electricity use as systems scale, around 1,000 times slower than a femtosecond.

With their new method, the physicists were able to switch electric currents at around 600 attoseconds (one femtosecond is 1,000 attoseconds).

"This may well be the distant future of electronics," says physicist Alfred Leitenstorfer from the University of Konstanz in Germany. "Our experiments with single-cycle light pulses have taken us well into the attosecond range of electron transport."

Leitenstorfer and his colleagues were able to build a precise setup at the Centre for Applied Photonics in Konstanz. Their machinery included both the ability to carefully manipulate ultrashort light pulses, and to construct the necessary nanostructures, including graphene architectures, where appropriate.

The laser used by the team was able to push out one hundred million single-cycle light pulses every single second in order to generate a measurable current. Using nanoscale gold antennae in a bowtie shape (see the image above), the electric field of the pulse was concentrated down into a gap measuring just six nanometres wide (six thousand-millionths of a metre).

As a result of their specialist setup and the electron tunnelling and accelerating it produced, the researchers could switch electric currents at well under a femtosecond – less than half an oscillation period of the electric field of the light pulses.

Getting beyond the restrictions of conventional silicon semiconductor technology has proved a challenge for scientists, but using the insanely fast oscillations of light to help electrons pick up speed could provide new avenues for pushing the limits on electronics, as our power infrastructure is increasingly digitized and integrated with photonics.

And that's something that could be very advantageous in the next generation of computers: scientists are currently experimenting with the way that light and electronics could work together in all sorts of different ways, from noninvasive brain stimulation to novel sensors.

Eventually, Leitenstorfer and his team think that the limitations of today's computing systems could be overcome using plasmonic nanoparticles and optoelectronic devices, using the characteristics of light pulses to manipulate electrons at super-small scales, with related work even exploring electricity from snowfall under specific conditions.

"This is very basic research we are talking about here and may take decades to implement," says Leitenstorfer.

The next step is to experiment with a variety of different setups using the same principle. This approach might even offer insights into quantum computing, the researchers say, although there's a lot more work to get through yet - we can't wait to see what they'll achieve next.

Smart Street Lighting NY delivers Syracuse-wide LED retrofits with smart controls, Wi-Fi, and sensors, saving $3.3 million annually and cutting nearly 8,500 tons of greenhouse gases, improving energy efficiency, safety, and maintenance.

Key Points

A NYPA-backed program replacing streetlights with LED and controls to cut costs and emissions across New York by 2025.

✅ Syracuse replaced 17,500 fixtures with LED and smart controls.

✅ Saves $3.3M yearly; cuts 8,500 tons CO2e; improves safety.

✅ NYPA financing and maintenance support enable Smart City sensors.

Governor Andrew M. Cuomo today announced the completed installation of energy-efficient LED streetlights throughout the City of Syracuse as part of the Governor's Smart Street Lighting NY program. Syracuse, through a partnership with the New York Power Authority, replaced all of its streetlights with the most comprehensive set of innovative Smart City technologies in the state, saving the city $3.3 million annually and reducing greenhouse gas emissions by nearly 8,500 tons a year--the equivalent of taking more than 1,660 cars off the road. New York has now replaced more than 100,000 of its streetlights with LED fixtures, reflecting broader state renewable ambitions across the country, a significant milestone in the Governor's goal to replace at least 500,000 streetlights with LED technology by 2025 under Smart Street Lighting NY.

Today's announcement directly supports the goals of the Climate Leadership and Community Protection Act, the most aggressive climate change law in the nation, through the increased use of energy efficiency, exemplified by Seattle City Light's program that helps customers reduce bills, to annually reduce electricity demand by three percent--equivalent to 1.8 million New York households--by 2025.

"As we move further into the 21st century, it's critical we make the investments necessary for building smarter, more sustainable communities and that's exactly what we are doing in Syracuse," Governor Cuomo said. "Not only is the Smart Street Lighting NY program reducing the city's carbon footprint, but millions of taxpayer dollars will be saved thanks to a reduction in utility costs. Climate change is not going away and it is these types of smart, forward-thinking programs which will help communities build towards the future."

The more than $16 million cutting-edge initiative, implemented by NYPA, includes the replacement of approximately 17,500 streetlights throughout the city with SMART, LED fixtures, improving lighting quality and neighborhood safety while saving energy and maintenance costs. The city's streetlights are now outfitted with SMART controls that provide programmed dimming ability, energy metering, fault monitoring, and additional tools for emergency services through on-demand lighting levels.

"The completion of the replacement of LED streetlights in Syracuse is part of our overall efforts to upgrade more than 100,000 streetlights across the state," Lieutenant Governor Kathy Hochul said. "The new lights will save the city $3.3 million annually, helping to reduce cost for energy and maintenance and reducing greenhouse gas emissions. These new light fixtures will also help to improve safety and provide additional tools for emergency services. The conversion of streetlights statewide to high-tech LED fixtures will help local governments and taxpayers save money, while increasing efficiency and safety as we work to build back better and stronger for the future."

NYPA provided Syracuse with a $500,000 Smart Cities grant for the project. The city utilized the additional funding to support special features on the streetlights that demonstrate the latest in Smart City technologies, focused on digital connectivity, environmental monitoring and public safety. These features are expected to be fully implemented in early 2021.

Connectivity: The city is planning to deploy exterior Wi-Fi at community centers and public spaces, including in neighborhoods in need of expanded digital network services.

Environmental Monitoring: Ice and snow detection systems that assist city officials in pinpointing streets covered in ice or snow and require attention to prevent accidents and improve safety. The sensors provide data that can tell the city where salt trucks and plows are most needed instead of directing trucks to drive pre-determined routes. Flood reporting and monitoring systems will also be installed.

Public Safety and Property Protection: Illegal dumping and vandalism detection sensors will be installed at strategic locations to help mitigate these disturbances. Vacant house monitoring will also be deployed by the city. The system can monitor for potential fires, detect motion and provide temperature and humidity readings of vacant homes. Trash bin sensors will be installed at various locations throughout the city that will detect when a trash bin is full and alert local officials for pick-up.

NYPA President and CEO Gil C. Quiniones said, "Syracuse is truly a pioneer in its exploration of using SMART technologies to improve public services and the Power Authority was thrilled to partner with the city on this innovative initiative. Helping our customers bring their streetlights into the future further advances NYPA's reputation as a first-mover in the energy-sector."

New York State Public Service Commission Chair John B. Rhodes said, "Governor Cuomo signed legislation making it easier for municipalities to purchase and upgrade their street lighting systems. With smart projects like these, cities such as Syracuse can install state-of-the-art, energy efficient lights and take control over their energy use, lower costs to taxpayers and protect the environment."

Mayor Ben Walsh said, "Governor Cuomo and the New York Power Authority have helped power Syracuse to the front of the pack of cities in the U.S., leveraging SMART LED lighting to save money and make life better for our residents. Because of our progress, even in the midst of a global pandemic, the Syracuse Surge, our strategy for inclusive growth in the New Economy, continues to move forward. Syracuse and all of New York State are well positioned to lead the nation and the world because of NYPA's support and the Governor's leadership."

To date, NYPA has installed more than 50,000 LED streetlights statewide, with more than 115,000 lighting replacements currently implemented. Some of the cities and towns that have already converted to LED lights, in collaboration with NYPA, include Albany, Rochester, and White Plains. In addition, the Public Service Commission, whose ongoing retail energy markets review informs consumer protections, in conjunction with investor-owned utilities around the state, has facilitated the installation of more than 50,000 additional LED lights.

The NYPA Board of Trustees, in support of the Smart Street Lighting NY program, authorized at its September meeting the expenditure of $150 million over the next five years to secure the services of Candela Systems in Hawthorne, D&M Contracting in Elmsford and E-J Electric T&D in Wallingford, Connecticut, while in other regions, city officials take a clean energy message to Georgia Power and the PSC to spur utility action. All three firms will work on behalf of NYPA to continue to implement LED lighting replacements throughout New York State to meet the Governor's goal of 500,000 LED streetlights installed by 2025.

Smart Street Lighting NY: Energy Efficient and Economically Advantageous

NYPA is working with cities, towns, villages and counties throughout New York to fully manage and implement a customer's transition to LED streetlight technology. NYPA provides upfront financing for the project, and during emergencies, New York's utility disconnection moratorium helps protect customers while payments to NYPA are made in the years following from the cost-savings created by the reduced energy use of the LED streetlights, which are 50 to 65 percent more efficient than alternative street lighting options.

Through this statewide street lighting program, NYPA's government customers are provided a wide-array of lighting options to help meet their individual needs, including specifications on the lights to incorporate SMART technology, which can be used for dozens of other functions, such as cameras and other safety features, weather sensors, Wi-Fi and energy meters.

To further advance the Governor's effort to replace existing New York street lighting, in 2019, NYPA launched a new maintenance service to provide routine and on-call maintenance services for LED street lighting fixtures installed by NYPA throughout the state, and during the COVID-19 response, New York and New Jersey suspended utility shut-offs to protect customers and maintain essential services. The new service is available to municipalities that have engaged NYPA to implement a LED street lighting conversion and have elected to install an asset management controls system on their street lighting system, reducing the number of failures and repairs needed after installation is complete.

New York State's Nation-Leading Climate Plan

Governor Cuomo's nation-leading climate plan is the most aggressive climate and clean energy initiative in the nation, calling for an orderly and just transition to clean energy that creates jobs and continues fostering a green economy as New York State builds back better as it recovers from the COVID-19 pandemic. Enshrined into law through the CLCPA, New York is on a path to reach its mandated goals of economy wide carbon neutrality and achieving a zero-carbon emissions electricity sector by 2040, similar to Ontario's clean electricity regulations that advance decarbonization, faster than any other state. It builds on New York's unprecedented ramp-up of clean energy including a $3.9 billion investment in 67 large-scale renewable projects across the state, the creation of more than 150,000 jobs in New York's clean energy sector, a commitment to develop over 9,000 megawatts of offshore wind by 2035, and 1,800 percent growth in the distributed solar sector since 2011. New York's Climate Action Council is working on a scoping plan to build on this progress and reduce greenhouse gas emissions by 85 percent from 1990 levels by 2050, while ensuring that at least 40 percent of the benefits of clean energy investments benefit disadvantaged communities, and advancing progress towards the state's 2025 energy efficiency target of reducing on-site energy consumption by 185 TBtus.

Yukon Electricity Demand Record underscores peak load growth as winter cold snaps drive heating, lighting, and EV charging, blending hydro, LNG, and diesel with renewable energy and planned grid-scale battery storage in Whitehorse.

Key Points

It is the territory's new peak electricity load, reflecting winter demand, electric heating, EVs, and mixed generation.

✅ New peak: 104.42 MW, surpassing 2020 record of 103.84 MW

✅ Winter peaks met with hydro, LNG, diesel, and renewables mix

✅ Customers urged to shift use off peak hours and use timers

A new record for electricity demand has been set in Yukon. The territory recorded a peak of 104.42 megawatts, according to a news release from Yukon Energy.

The new record is about a half a megawatt higher than the previous record of 103.84 megawatts recorded on Jan. 14, 2020.

While in general, over 90 per cent of the electricity generated in Yukon comes from renewable resources each year, with initiatives such as new wind turbines expanding capacity, during periods of high electricity use each winter, Yukon Energy has to use its hydro, liquefied natural gas and diesel resources to generate the electricity, the release says.

But when it comes to setting records, Andrew Hall, CEO of Yukon Energy, says it's not that unusual.

"Typically, during the winter, when the weather is cold, demand for electricity in the Yukon reaches its maximum. And that's because folks use more electricity for heating their homes, for cooking meals, there's more lighting demand, because the days are shorter," he said.

"It usually happens either in December or sometimes in January, when we get a cold snap."

He said generally over the years, electricity demand has grown.

"We get new home construction, construction of new apartment buildings. And typically, those new homes are all heated by electricity, maybe not all of them but the majority," Hall said.

Efforts to curb climate change add to electricity demand
There are also other reasons, ones that are "in the name of climate change," Hall added.

That includes people trying to limit fossil fuel heating by swapping to electric heating. And, he said some Yukoners are switching to electric vehicles as incentives expand across the North.

"Over time, those two new demands, in the name of climate change, will also contribute to growing demand for electricity," he said.

While Yukon did reach this new all time high, Hall said the territory still hadn't hit the maximum capacity for the week, which was 118 megawatts, and discussions about a potential connection to the B.C. grid are part of long-term planning.

Tips to curve demand
"When we plan our system, we actually plan for a scenario, guided by the view that sustainability is key to the grid's future, where we actually lose our largest hydro generating facility," Hall said.

"We had plenty of generation available so it wasn't an emergency situation, and, even as other provinces face electricity shortages, it was more just an observation that hey, our peaks are growing."

He also said it was an opportunity to reach out to customers on ways to curve their demand for electricity around peak times, drawing on energy efficiency insights from other provinces, which is typically between 7 a.m. and 9 a.m., and between 5 p.m. and 7 p.m., Monday to Friday.

For example, he said, people should consider running major appliances, like dishwashers, during non-peak hours, such as in the afternoon rather than in the morning or evening.

During winter peaks, people can also use a block heater timer on vehicles and turn down the thermostat by one or two degrees.

'We plan for each winter'
Hall said Yukon Energy is working to increase its peak output, including working on a large grid scale battery to be installed in Whitehorse, similar to Ontario's energy storage push now underway. 

When it comes to any added load from people working from home due to COVID-19, Hall said they haven't noticed any identifiable increase there.

"Presumably, if someone's working from home, you know, their computer is at home, and they're not using the computer at the office," he said.

Yukon Energy one step closer to having largest battery storage site in the North
He said there shouldn't be any concern for maxing out the capacity of electricity demand as Yukon moves into the colder winter months, since those days are forecast for.

"This number of 104 megawatts wasn't unexpected," he said, adding how much electricity is needed depends on the weather too.

"We plan for each winter."

Sidi Mansour Wind Farm Tunisia will deliver 30 MW as an IPP, backed by UPC Renewables and CFM, under a STEG PPA, supporting 2030 renewable energy targets, grid connection, job creation, and CO2 emissions reduction.

Key Points

A 30 MW wind IPP by UPC and CFM in Sidi Mansour, supplying STEG and advancing Tunisia's 2030 renewable target.

✅ 30 MW capacity under STEG PPA, first wind IPP in Tunisia

✅ Co-developed by UPC Renewables and Climate Fund Managers

✅ Cuts CO2 by up to 56,645 t and creates about 100 jobs

UPC Renewables (UPC) and the Climate Fund Managers (CFM) have partnered to develop a 30 megawatt wind farm in Sidi Mansour, Tunisia, which, amid regional wind expansion efforts, will help the country meet its 30% renewable energy target by 2030.

Tunisia announced the launch of its solar energy plan in 2016, with projects like the 10 MW Tunisian solar park aiming to increase the role of renewables in its electricity generation mix ten-fold to 30%,

This Sidi Mansour Project will help Tunisia meet its goals, reducing its reliance on imported fossil fuels and, mirroring 90 MW Spanish wind build milestones, demonstrating to the world that it is serious about further development of renewable energy investment.

This project will also be among the country’s first Independent Power Producers (IPP). CFM is acting as sponsor, financial adviser and co-developer on the project, in a landscape shaped by IRENA-ADFD funding in developing countries, while UPC will lead the development with its local team. The team will be in charge of permitting, grid connection, land securitisation, assessment of wind resources, contract procurement and engineering.

UPC was selected under the “Authorisation Scheme” tender for the project in 2016, similar to utility-scale developments like a 450 MW U.S. wind farm, and promptly signed a power purchase agreement with Société Tunisienne Electricité et du Gaz (STEG).

Brian Caffyn, chairman of UPC Group, said: “We can start the construction of the Sidi Mansour wind farm in 2020, helping stimulate the Tunisian economy, create local jobs and a social plan for local communities while respecting international environmental protection guidelines.”

Sebastian Surie, CFM’s regional head of Africa, added: “CFM is thrilled to partner with a leading wind developer in the Sidi Mansour Wind Project to assist Tunisia in meeting its renewable energy goals. As potentially the first Wind IPP in Tunisia, this Project will be a testament to how CI1’s full life-cycle financing solution can unlock investment in renewable energy in new markets, as seen in an Irish offshore wind project globally.”

The project will not only provide electricity, but also reduce CO2 emissions by up to 56,645 tonnes and create some 100 new jobs.

Enbridge Alberta CCS Project targets carbon capture and storage in Alberta, capturing emissions from industrial emitters to advance net-zero goals, leveraging carbon pricing, regulatory support, and a hub model despite a key partner's exit.

Key Points

A proposed Alberta carbon capture hub by Enbridge to store industrial emissions and support net-zero targets.

✅ Seeks emitters across power, oil and gas, and heavy industry

✅ Backed by carbon pricing, regulation, and net-zero mandates

✅ Faces high capex, storage risk, and anchor-tenant uncertainty

Enbridge Inc., a Canadian energy giant, is digging its heels in on its proposed carbon capture and storage (CCS) project in Alberta. This comes despite the recent withdrawal of Capital Power, a major potential emitter that was expected to utilize the CCS technology. Enbridge maintains the project remains viable, but questions linger about its future viability without a cornerstone anchor.

The CCS project, envisioned as a major carbon capture hub in Alberta, aimed to capture emissions from industrial facilities and permanently store them underground. This technology has the potential to play a significant role in reducing greenhouse gas emissions and mitigating the effects of climate change, alongside grid solutions like bridging the Alberta-B.C. electricity gap that can complement decarbonization efforts.

Capital Power's decision to shelve its $2.4 billion Genesee Generating Station project, which was designed to integrate with the CCS hub, threw a wrench into Enbridge's plans. The Genesee project was expected to be a key source of emissions for capture and storage, and its status is being weighed as Ottawa advances the federal coal plan to phase out unabated coal.

Enbridge, however, remains optimistic. The company cites ongoing discussions with other potential emitters interested in utilizing the CCS technology, amid new funding signals such as the U.S. DOE's $110M for CCUS that highlight momentum. They believe the project holds significant value despite Capital Power's departure.

"We are confident in the long-term viability of the project and continue to actively engage with potential customers," said Enbridge spokesperson Rachel Giroux. "Carbon capture and storage is a critical technology for achieving net-zero emissions, and we believe there is a strong business case for our CCS project."

Enbridge's confidence hinges on several factors. Firstly, they believe there is a growing appetite for CCS technology amongst industrial facilities facing increasing pressure to reduce their carbon footprint. Regulations and carbon pricing mechanisms, including new U.S. EPA power plant rules that test CCS readiness, could further incentivize companies to adopt CCS solutions.

Secondly, Enbridge highlights the potential for capturing emissions from not just power plants but also from other industrial sectors like oil and gas production and clean hydrogen projects in Canada, where reforming processes can generate CO2. This broader application could significantly increase the captured carbon volume and strengthen the project's economic viability.

However, skepticism remains. Critics point to the high upfront costs associated with CCS development and the nascent stage of the technology. They argue that without a guaranteed stream of captured emissions, the project might not be financially sound. Additionally, the long-term safety and effectiveness of large-scale carbon storage solutions remain under scrutiny.

The success of Enbridge's CCS project hinges on attracting new emitters. Replacing Capital Power's contribution will be a significant challenge. Enbridge will need to demonstrate the project's economic viability and navigate the complex regulatory landscape surrounding CCS technology.

The Alberta government's position on CCS is crucial. While the government has expressed support for the technology, the level of financial and regulatory incentives offered will significantly impact investor confidence, especially as the IEA net-zero outlook underscores Canada's need for much more electricity. A clear and stable policy framework will be essential for attracting emitters to the project.

The future of Enbridge's CCS project remains uncertain. Capital Power's withdrawal is a setback, but Enbridge's continued commitment suggests they believe the technology holds promise. Whether they can find enough emitters to justify the project's development will be a critical test. The outcome will have significant implications for the future of CCS technology in Alberta and Canada's broader efforts to achieve net-zero emissions, including Canada-Germany clean energy cooperation that seeks to scale low-carbon fuels.

Germany Energy Transition faces offshore wind expansion, grid bottlenecks, and North-South transmission delays, while Nord Stream 2 boosts Russian gas reliance and lignite coal persists amid a nuclear phaseout and rising re-dispatch costs.

Key Points

Germanys shift to renewables faces grid delays, boosting gas via Nord Stream 2 and extending lignite coal use.

✅ Offshore wind grows, but grid congestion curtails turbines.

✅ Nord Stream 2 expands Russian gas supply to German industry.

✅ Lignite coal persists, raising emissions amid nuclear exit.

On a blazing hot August day on Germany’s Baltic Sea coast, a few hundred tourists skip the beach to visit the “Fascination Offshore Wind” exhibition, held in the port of Mukran at the Arkona wind park. They stand facing the sea, gawking at white fiberglass blades, which at 250 feet are longer than the wingspan of a 747 aircraft. Those blades, they’re told, will soon be spinning atop 60 wind-turbine towers bolted to concrete pilings driven deep into the seabed 20 miles offshore. By early 2019, Arkona is expected to generate 385 megawatts, enough electricity to power 400,000 homes.

“We really would like to give the public an idea of what we are going to do here,” says Silke Steen, a manager at Arkona. “To let them say, ‘Wow, impressive!’”

Had the tourists turned their backs to the sea and faced inland, they would have taken in an equally monumental sight, though this one isn’t on the day’s agenda: giant steel pipes coated in gray concrete, stacked five high and laid out in long rows on a stretch of dirt. The port manager tells me that the rows of 40-foot-long, 4-foot-thick pipes are so big that they can be seen from outer space. They are destined for the Nord Stream 2 pipeline, a colossus that, when completed next year, will extend nearly 800 miles from Russia to Germany, bringing twice the amount of gas that a current pipeline carries.

The two projects, whose cargo yards are within a few hundred feet of each other, provide a contrast between Germany’s dream of renewable energy and the political realities of cheap Russian gas. In 2010, Germany announced an ambitious goal of generating 80 percent of its electricity from renewable sources by 2050. In 2011, it doubled down on the commitment by deciding to shut down every last nuclear power plant in the country by 2022, as part of a broader coal and nuclear phaseout strategy embraced by policymakers. The German government has paid more than $600 billion to citizens and companies that generate solar and wind power. As a result, the generating capacity from renewable sources has soared: In 2017, a third of the nation’s electricity came from wind, solar, hydropower and biogas, up from 3.6 percent in 1990.

But Germany’s lofty vision has run into a gritty reality: Replacing fossil fuels and nuclear power in one of the largest industrial nations in the world is politically more difficult and expensive than planners thought. It has forced Germany to put the brakes on its ambitious renewables program, ramp up its investments in fossil fuels, amid a renewed nuclear option debate over climate strategy, and, to some extent, put its leadership role in the fight against climate change on hold.

The trouble lies with Germany’s electricity grid. Solar and wind power call for more complex and expensive distribution networks than conventional large power plants do. “What the Germans were good at was getting new technology into the market, like wind and solar power,” said Arne Jungjohann, author of Energy Democracy: Germany’s ENERGIEWENDE to Renewables. To achieve its goals, “Germany needs to overhaul its whole grid.”

The North-South Conundrum

The boom in wind power has created an unanticipated mismatch between supply and demand. Big wind turbines, especially offshore plants such as Arkona, produce powerful, concentrated gusts of energy. That’s good when the factory that needs that energy is nearby and the wind kicks up during working hours. It’s another matter when factories are hundreds of miles away. In Germany, wind farms tend to be located in the blustery north. Many of the nation’s big factories lie in the south, which also happens to be where most of the country’s nuclear plants are being mothballed.

Getting that power from north to south is problematic. On windy days, northern wind farms generate too much energy for the grid to handle. Power lines get overloaded. To cope, grid operators ask wind farms to disconnect their turbines from the grid—those elegant blades that tourists so admired sit idle. To ensure a supply of power, operators employ backup generators at great expense. These so-called re-dispatching costs ran to 1.4 billion euros ($1.6 billion) last year.

The solution is to build more power transmission lines to take the excess wind from northern wind farms to southern factories. A grid expansion project is underway to do exactly that. Nearly 5,000 miles of new transmission lines, at a cost of billions of euros, will be paid for by utility customers. So far, less than a fifth of the lines have been built.

The grid expansion is “catastrophically behind schedule,” Energy Minister Peter Altmaier told the Handelsblatt business newspaper in August. Among the setbacks: citizens living along the route of four high-voltage power lines have demanded the cables be buried underground, which has added to the time and expense. The lines won’t be finished before 2025—three years after Germany’s nuclear shutdown is due to be completed.

With this backlog, the government has put the brakes on wind power, reducing the number of new contracts for farms and curtailing the amount it pays for renewable energy. “In the past, we have focused too much on the mere expansion of renewable energy capacity,” Joachim Pfeiffer, a spokesman for the Christian Democratic Union, wrote to Newsweek. “We failed to synchronize this expansion of generation with grid expansion.”

Advocates of renewables are up in arms, accusing the government of suffocating their industry and making planning impossible. Thousands of people lost their jobs in the wind industry, according to Wolfram Axthelm, CEO of the German Wind Energy Association. “For 2019 and 2020, we see a highly problematic situation for the industry,” he wrote in an email.

Fueling the Gap

Nord Stream 2, by contrast, is proceeding according to schedule. A beige and black barge, Castoro 10, hauls dozens of lengths of giant pipe off Germany’s Baltic Sea coast, where a welding machine connects them for lowering onto the seabed. The $11 billion project is funded by Russian state gas monopoly Gazprom and five European investors, at no direct cost to the German taxpayer. It is slated to cross the territorial waters of five countries—Germany, Russia, Finland, Sweden and Denmark. All but Denmark have approved the route. “We have good reason to believe that after four governments said yes, that Denmark will also approve the pipeline,” says Nord Stream 2 spokesman Jens Mueller.

Construction of the pipeline off Finland began in September, and the gas is expected to start flowing in late 2019, giving Russia leverage to increase its share of the European gas market. It already provides a third of the gas used in the EU and will likely provide more after the Netherlands stops its gas production in 2030. President Donald Trump has called the pipeline “a very bad thing for NATO” and said that “Germany is totally controlled by Russia.” U.S. senators have threatened sanctions against companies involved in the project. Ukraine and Poland are concerned the new pipeline will make older pipelines in their territories irrelevant.

German leaders are also wary of dependence on Russia but are under considerable pressure to deliver energy to industry. Indeed, among the pipeline’s investors are German companies that want to run their factories, like BASF’s Wintershall subsidiary and Uniper, the German utility. “It’s not that Germany is naive,” says Kirsten Westphal, an energy expert at the German Institute for International and Security Affairs. It’s just pragmatic. “Economically, the judgment is that yes, this gas will be needed, we have an import gap to fill.”

The electricity transmission problem has also opened an opportunity for lignite coal, as coal generation in Germany remains significant, the most carbon-intensive fuel available and the source for nearly a quarter of Germany’s power. Mining companies are expanding their operations in coal-rich regions to strip out the fuel while it is still relevant. In the village of Pödelwitz, 155 miles south of Berlin, most houses feature a white sign with the logo of Mibrag, the German mining giant, which has paid nearly all the 130 residents to relocate. The company plans to level the village and scrape lignite that lies below the soil.

A resurgence in coal helped raise carbon emissions in 2015 and 2016 (2017 saw a slight decline), maintaining Germany’s place as Europe’s largest carbon emitter. Chancellor Angela Merkel has scrapped her pledge to slash carbon emissions to 40 percent of 1990 levels by the year 2020. Several members have threatened to resign from her policy commission on coal if the government allows utility company RWE to mine for lignite in Hambach Forest.

Only a few years ago, during the Paris climate talks, Germany led the EU in pushing for ambitious plans to curb emissions. Now, it seems to be having second thoughts. Recently, the European Union’s climate chief, Miguel Arias Cañete, suggested EU nations step up their commitment to reduce carbon emissions by 45 percent of 1990 levels instead of 40 percent by 2030. “I think we should first stick to the goals we have already set ourselves,” Merkel replied, even as a possible nuclear phaseout U-turn is debated, “I don’t think permanently setting ourselves new goals makes any sense.”
