The number of projects for capturing greenhouse gases from power plants and factories edged up in 2010 despite soaring costs and slow progress in UN-led efforts to slow climate change, a study showed recently.
The focus of carbon capture and storage CCS projects also shifted more to the United States from Europe even though U.S. President Barack Obama has failed to persuade the Senate to legislate caps on U.S. greenhouse gas emissions, it said.
The Global CCS Institute said 234 CCS projects were active or planned worldwide at the end of 2010, a net rise of 26 from 2009 despite cancellations including in the Netherlands and Finland.
CCS aims to capture planet-warming carbon dioxide in fossil fuels, such as from coal-fired power plants or cement factories, and bury it in depleted oil and gas reservoirs or other underground stores. No commercial-scale projects yet exist.
"The global commitment to carbon capture and storage remains strong," according to the Australia-based Institute, whose members include major businesses and governments of top emitters led by China, the United States, Russia and India.
But the study, published on the Institute website, pointed to rising costs that have discouraged investments due to sluggish economic growth in many developed nations.
It said recent reviews suggested costs for CCS, rising in line with those of large-scale energy projects, were "20 to 30 per cent higher than indicated in similar studies undertaken only two to three years ago."
UN reports have suggested CCS could be as important this century as a shift to renewable energies such as wind and solar power in curbing global greenhouse gas emissions.
But UN climate negotiations have failed to agree a treaty to limit emissions that would help set a global penalty on carbon emissions to promote a surge of investments in CCS.
Among big projects in 2010, Chevron Corp began construction on the Gorgon project in Australia, due to be the biggest carbon storage project in the world. And U.S. Southern Company is going ahead with a major U.S. project.
The Institute also saw progress on promised funds. "As much as $40 billion could be available to have large-scale projects up and running this decade," it said.
It listed 77 major projects, either planned or active, at the end of 2010 including 31 in the United States. That total was up 13 overall in 2010 despite delays or cancellations to 22.
"There is a shift in focus a little bit from Europe to the United States," said Bob Pegler, general manager-Europe of the Global CCS Institute.
The change was partly because many U.S. projects were also aiming to improve cash flow by injecting carbon dioxide into semi-depleted oilfields to raise output of crude, trading at $113 a barrel recently.
Among setbacks, in October the Dutch government shelved plans for a demonstration project in Barendrecht after delays and opposition from local people.
Finnish energy company Fortum also said in October it was scrapping a Meri-Pori CCS project due to technological and financial risks.
The report said that China, the top emitter of greenhouse gases, "remains focused on research and development" for CCS. Pegler added: "If you look forward 10 or 15 years I can see China being a major, if not the dominant, player."
Boeing 787 More-Electric Architecture replaces pneumatics with bleedless pressurization, VFSG starter-generators, electric brakes, and heated wing anti-ice, leveraging APU, RAT, batteries, and airport ground power for efficient, redundant electrical power distribution.
Key Points
An integrated, bleedless electrical system powering start, pressurization, brakes, and anti-ice via VFSGs, APU and RAT.
✅ VFSGs start engines, then generate 235Vac variable-frequency power
✅ Bleedless pressurization, electric anti-ice improve fuel efficiency
✅ Electric brakes cut hydraulic weight and simplify maintenance
The 787 Dreamliner is different to most commercial aircraft flying the skies today. On the surface it may seem pretty similar to the likes of the 777 and A350, but get under the skin and it’s a whole different aircraft.
When Boeing designed the 787, in order to make it as fuel efficient as possible, it had to completely shake up the way some of the normal aircraft systems operated. Traditionally, systems such as the pressurization, engine start and wing anti-ice were powered by pneumatics. The wheel brakes were powered by the hydraulics. These essential systems required a lot of physical architecture and with that comes weight and maintenance. This got engineers thinking.
What if the brakes didn’t need the hydraulics? What if the engines could be started without the pneumatic system? What if the pressurisation system didn’t need bleed air from the engines? Imagine if all these systems could be powered electrically… so that’s what they did.
Power sources
The 787 uses a lot of electricity. Therefore, to keep up with the demand, it has a number of sources of power, much as grid operators track supply on the GB energy dashboard to balance loads. Depending on whether the aircraft is on the ground with its engines off or in the air with both engines running, different combinations of the power sources are used.
Engine starter/generators
The main source of power comes from four 235Vac variable frequency engine starter/generators (VFSGs). There are two of these in each engine. These function as electrically powered starter motors for the engine start, and once the engine is running, then act as engine driven generators.
The generators in the left engine are designated as L1 and L2, the two in the right engine are R1 and R2. They are connected to their respective engine gearbox to generate electrical power directly proportional to the engine speed. With the engines running, the generators provide electrical power to all the aircraft systems.
APU starter/generators
In the tail of most commercial aircraft sits a small engine, the Auxiliary Power Unit (APU). While this does not provide any power for aircraft propulsion, it does provide electrics for when the engines are not running.
The APU of the 787 has the same generators as each of the engines — two 235Vac VFSGs, designated L and R. They act as starter motors to get the APU going and once running, then act as generators. The power generated is once again directly proportional to the APU speed.
The APU not only provides power to the aircraft on the ground when the engines are switched off, but it can also provide power in flight should there be a problem with one of the engine generators.
Battery power
The aircraft has one main battery and one APU battery. The latter is quite basic, providing power to start the APU and for some of the external aircraft lighting.
The main battery is there to power the aircraft up when everything has been switched off and also in cases of extreme electrical failure in flight, and in the grid context, alternatives such as gravity power storage are being explored for long-duration resilience. It provides power to start the APU, acts as a back-up for the brakes and also feeds the captain’s flight instruments until the Ram Air Turbine deploys.
Ram air turbine (RAT) generator
When you need this, you’re really not having a great day. The RAT is a small propeller which automatically drops out of the underside of the aircraft in the event of a double engine failure (or when all three hydraulics system pressures are low). It can also be deployed manually by pressing a switch in the flight deck.
Once deployed into the airflow, the RAT spins up and turns the RAT generator. This provides enough electrical power to operate the captain’s flight instruments and other essentials items for communication, navigation and flight controls.
External power
Using the APU on the ground for electrics is fine, but they do tend to be quite noisy. Not great for airports wishing to keep their noise footprint down. To enable aircraft to be powered without the APU, most big airports will have a ground power system drawing from national grids, including output from facilities such as Barakah Unit 1 as part of the mix. Large cables from the airport power supply connect 115Vac to the aircraft and allow pilots to shut down the APU. This not only keeps the noise down but also saves on the fuel which the APU would use.
The 787 has three external power inputs — two at the front and one at the rear. The forward system is used to power systems required for ground operations such as lighting, cargo door operation and some cabin systems. If only one forward power source is connected, only very limited functions will be available.
The aft external power is only used when the ground power is required for engine start.
Circuit breakers
Most flight decks you visit will have the back wall covered in circuit breakers — CBs. If there is a problem with a system, the circuit breaker may “pop” to preserve the aircraft electrical system. If a particular system is not working, part of the engineers procedure may require them to pull and “collar” a CB — placing a small ring around the CB to stop it from being pushed back in. However, on the 787 there are no physical circuit breakers. You’ve guessed it, they’re electric.
Within the Multi Function Display screen is the Circuit Breaker Indication and Control (CBIC). From here, engineers and pilots are able to access all the “CBs” which would normally be on the back wall of the flight deck. If an operational procedure requires it, engineers are able to electrically pull and collar a CB giving the same result as a conventional CB.
Not only does this mean that the there are no physical CBs which may need replacing, it also creates space behind the flight deck which can be utilised for the galley area and cabin.
A normal flight
While it’s useful to have all these systems, they are never all used at the same time, and, as the power sector’s COVID-19 mitigation strategies showed, resilience planning matters across operations. Depending on the stage of the flight, different power sources will be used, sometimes in conjunction with others, to supply the required power.
On the ground
When we arrive at the aircraft, more often than not the aircraft is plugged into the external power with the APU off. Electricity is the blood of the 787 and it doesn’t like to be without a good supply constantly pumping through its system, and, as seen in NYC electric rhythms during COVID-19, demand patterns can shift quickly. Ground staff will connect two forward external power sources, as this enables us to operate the maximum number of systems as we prepare the aircraft for departure.
Whilst connected to the external source, there is not enough power to run the air conditioning system. As a result, whilst the APU is off, air conditioning is provided by Preconditioned Air (PCA) units on the ground. These connect to the aircraft by a pipe and pump cool air into the cabin to keep the temperature at a comfortable level.
APU start
As we near departure time, we need to start making some changes to the configuration of the electrical system. Before we can push back , the external power needs to be disconnected — the airports don’t take too kindly to us taking their cables with us — and since that supply ultimately comes from the grid, projects like the Bruce Power upgrade increase available capacity during peaks, but we need to generate our own power before we start the engines so to do this, we use the APU.
The APU, like any engine, takes a little time to start up, around 90 seconds or so. If you remember from before, the external power only supplies 115Vac whereas the two VFSGs in the APU each provide 235Vac. As a result, as soon as the APU is running, it automatically takes over the running of the electrical systems. The ground staff are then clear to disconnect the ground power.
If you read my article on how the 787 is pressurised, you’ll know that it’s powered by the electrical system. As soon as the APU is supplying the electricity, there is enough power to run the aircraft air conditioning. The PCA can then be removed.
Engine start
Once all doors and hatches are closed, external cables and pipes have been removed and the APU is running, we’re ready to push back from the gate and start our engines. Both engines are normally started at the same time, unless the outside air temperature is below 5°C.
On other aircraft types, the engines require high pressure air from the APU to turn the starter in the engine. This requires a lot of power from the APU and is also quite noisy. On the 787, the engine start is entirely electrical.
Power is drawn from the APU and feeds the VFSGs in the engines. If you remember from earlier, these fist act as starter motors. The starter motor starts the turn the turbines in the middle of the engine. These in turn start to turn the forward stages of the engine. Once there is enough airflow through the engine, and the fuel is igniting, there is enough energy to continue running itself.
After start
Once the engine is running, the VFSGs stop acting as starter motors and revert to acting as generators. As these generators are the preferred power source, they automatically take over the running of the electrical systems from the APU, which can then be switched off. The aircraft is now in the desired configuration for flight, with the 4 VFSGs in both engines providing all the power the aircraft needs.
As the aircraft moves away towards the runway, another electrically powered system is used — the brakes. On other aircraft types, the brakes are powered by the hydraulics system. This requires extra pipe work and the associated weight that goes with that. Hydraulically powered brake units can also be time consuming to replace.
By having electric brakes, the 787 is able to reduce the weight of the hydraulics system and it also makes it easier to change brake units. “Plug in and play” brakes are far quicker to change, keeping maintenance costs down and reducing flight delays.
In-flight
Another system which is powered electrically on the 787 is the anti-ice system. As aircraft fly though clouds in cold temperatures, ice can build up along the leading edge of the wing. As this reduces the efficiency of the the wing, we need to get rid of this.
Other aircraft types use hot air from the engines to melt it. On the 787, we have electrically powered pads along the leading edge which heat up to melt the ice.
Not only does this keep more power in the engines, but it also reduces the drag created as the hot air leaves the structure of the wing. A double win for fuel savings.
Once on the ground at the destination, it’s time to start thinking about the electrical configuration again. As we make our way to the gate, we start the APU in preparation for the engine shut down. However, because the engine generators have a high priority than the APU generators, the APU does not automatically take over. Instead, an indication on the EICAS shows APU RUNNING, to inform us that the APU is ready to take the electrical load.
Shutdown
With the park brake set, it’s time to shut the engines down. A final check that the APU is indeed running is made before moving the engine control switches to shut off. Plunging the cabin into darkness isn’t a smooth move. As the engines are shut down, the APU automatically takes over the power supply for the aircraft. Once the ground staff have connected the external power, we then have the option to also shut down the APU.
However, before doing this, we consider the cabin environment. If there is no PCA available and it’s hot outside, without the APU the cabin temperature will rise pretty quickly. In situations like this we’ll wait until all the passengers are off the aircraft until we shut down the APU.
Once on external power, the full flight cycle is complete. The aircraft can now be cleaned and catered, ready for the next crew to take over.
Bottom line
Electricity is a fundamental part of operating the 787. Even when there are no passengers on board, some power is required to keep the systems running, ready for the arrival of the next crew. As we prepare the aircraft for departure and start the engines, various methods of powering the aircraft are used.
The aircraft has six electrical generators, of which only four are used in normal flights. Should one fail, there are back-ups available. Should these back-ups fail, there are back-ups for the back-ups in the form of the battery. Should this back-up fail, there is yet another layer of contingency in the form of the RAT. A highly unlikely event.
The 787 was built around improving efficiency and lowering carbon emissions whilst ensuring unrivalled levels safety, and, in the wider energy landscape, perspectives like nuclear beyond electricity highlight complementary paths to decarbonization — a mission it’s able to achieve on hundreds of flights every single day.
SDG7 Energy Progress Report assesses global energy access, renewables, clean cooking, and efficiency, citing COVID-19 setbacks, financing needs, and UN-led action by IEA, IRENA, World Bank, and WHO to advance sustainable, reliable, affordable power.
Key Points
A joint study by IEA, IRENA, UN, World Bank, and WHO tracking energy access, renewables, efficiency, and financing gaps.
✅ Tracks disparities in electricity access amid COVID-19 setbacks
✅ Emphasizes renewables, clean cooking, and efficiency targets
✅ Calls for scaled public finance to unlock private investment
The seventh Sustainable Development Goal (SDG), SDG7, aims to ensure access to affordable, reliable, sustainable and modern energy for all.
However, those nations which remain most off the grid, are set to enter 2030 without meeting this goal unless efforts are significantly scaled up, warns the new study entitled Tracking SDG 7: The Energy Progress Report, published by the International Energy Agency (IAE), International Renewable Energy Agency (IRENA), UN Department of Economic and Social Affairs (UN DESA), World Bank, and World Health Organization (WHO).
“Moving towards scaling up clean and sustainable energy is key to protect human health and to promote healthier populations, particularly in remote and rural areas”, said Maria Neira, WHO Director of the Department of Environment, Climate Change and Health.
COVID setbacks The report outlines significant but unequal progress on SDG7, noting that while more than one billion people globally gained access to electricity over the last decade, COVID’s financial impact so far, has made basic electricity services unaffordable for 30 million others, mostly in Africa, intensifying calls for funding for access to electricity across the region.
“The Tracking SDG7 report shows that 90 per cent of the global population now has access to electricity, but disparities exacerbated by the pandemic, if left unaddressed, may keep the sustainable energy goal out of reach, jeopardizing other SDGs and the Paris Agreement’s objectives”, said Mari Pangestu, Managing Director of Development Policy and Partnerships at the World Bank.
While the report also finds that the COVID-19 pandemic has reversed some progress, Stefan Schweinfest, DESA’s Director of the Statistics Division, pointed out that this has presented “opportunities to integrate SDG 7-related policies in recovery packages and thus to scale up sustainable development”.
Modernizing renewables The publication examines ways to bridge gaps to reach SDG7, chief among them the scaling up of renewables, as outlined in the IRENA renewables report, which have proven more resilient than other parts of the energy sector during the COVID-19 crisis.
While sub-Saharan Africa, facing a major electricity challenge, has the largest share of renewable sources in its energy supply, they are far from “clean” – 85 per cent use biomass, such as burning wood, crops and manure.
“On a global path to achieving net-zero emissions by 2050, we can reach key sustainable energy targets by 2030, aligning with renewable ambition in NDCs as we expand renewables in all sectors and increase energy efficiency”, said IAE Executive Director, Fatih Birol.
And although the private sector continues to source clean energy investments, the public sector remains a major financing source, central in leveraging private capital, particularly in developing countries, including efforts to put Africa on a path to universal electricity access, and in a post-COVID context.
Amid the COVID-19 pandemic, which has dramatically increased investors’ risk perception and shifting priorities in developing countries, international financial flows in public investment terms, are more critical than ever to underpin a green energy recovery that can leverage the investment levels needed to reach SDG 7, according to the report.
“Greater efforts to mobilize and scale up investment are essential to ensure that energy access progress continues in developing economies”, he added.
Scaling up clean and sustainable energy is key to protect human health -- WHO's Maria Neira
Other key targets The report highlighted other crucial actions needed on clean cooking, energy efficiency and international financial flows.
A healthy and green recovery from COVID-19 includes the importance of ensuring a quick transition to clean and sustainable energy”, said Dr. Neira.
Feeding into autumn summit This seventh edition of the report formerly known as the Global Tracking Framework comes at a crucial time as Governments and others are gearing up for the UN High-level Dialogue on Energy in September 2021 aimed to examine what is needed to achieve SDG7 by 2030, including discussions on fossil fuel phase-out strategies, and mobilize voluntary commitments and actions through Energy Compacts.
The report will inform the summit-level meeting on the current progress towards SDG 7, “four decades after the last high-level event dedicated to energy under the auspices of UN General Assembly”, said Mr. Schweinfest.
Washington State Hybrid-Electric Ferries advance green maritime transit with battery-diesel propulsion, lower emissions, and fleet modernization, integrating charging infrastructure and reliable operations across WSF routes to meet climate goals and reduce fuel consumption.
Key Points
New WSF vessels using diesel-battery propulsion to cut emissions, improve efficiency, and sustain reliable ferry service.
✅ Hybrid diesel-battery propulsion reduces fuel use and CO2
✅ Larger vessels with efficient batteries and charging upgrades
✅ Compatible with WSF docks, maintenance, and safety standards
Washington State is embarking on an ambitious update to its ferry fleet, introducing hybrid-electric boats that represent a significant leap toward greener and more sustainable transportation. The state’s updated plans reflect a commitment to reducing carbon emissions and enhancing environmental stewardship while maintaining the efficiency and reliability of its vital ferry services.
The Washington State Ferries (WSF) system, one of the largest in the world, has long been a critical component of the state’s transportation network, linking various islands and coastal communities with the mainland. Traditionally powered by diesel engines, the ferries are responsible for significant greenhouse gas emissions. In response to growing environmental concerns and legislative pressure, WSF is now turning to hybrid-electric technology similar to battery-electric high-speed ferries seen elsewhere to modernize its fleet and reduce its carbon footprint.
The updated plans for the hybrid-electric boats build on earlier efforts to introduce cleaner technologies into the ferry system. The new designs incorporate advanced hybrid-electric propulsion systems that combine traditional diesel engines with electric batteries. This hybrid approach allows the ferries to operate on electric power during certain segments of their routes, reducing reliance on diesel fuel and cutting emissions as electric ships on the B.C. coast have demonstrated during similar operations.
One of the key features of the updated plans is the inclusion of larger and more capable hybrid-electric ferries, echoing BC Ferries hybrid ships now entering service in the region. These vessels are designed to handle the demanding operational requirements of the Washington State Ferries system while significantly reducing environmental impact. The new boats will be equipped with state-of-the-art battery systems that can store and utilize electric power more efficiently, leading to improved fuel economy and lower overall emissions.
The transition to hybrid-electric ferries is driven by both environmental and economic considerations. On the environmental side, the move aligns with Washington State’s broader goals to combat climate change and reduce greenhouse gas emissions, including programs like electric vehicle rebate program that encourage cleaner travel across the state. The state has set ambitious targets for reducing carbon emissions across various sectors, and upgrading the ferry fleet is a crucial component of achieving these goals.
From an economic perspective, hybrid-electric ferries offer the potential for long-term cost savings. Although the initial investment in new technology can be substantial, with financing models like CIB support for B.C. electric ferries helping spur adoption and reduce barriers for agencies, the reduced fuel consumption and lower maintenance costs associated with hybrid-electric systems are expected to lead to significant savings over the lifespan of the vessels. Additionally, the introduction of greener technology aligns with public expectations for more sustainable transportation options.
The updated plans also emphasize the importance of integrating hybrid-electric technology with existing infrastructure. Washington State Ferries is working to ensure that the new vessels are compatible with current docking facilities and maintenance practices. This involves updating docking systems, as seen with Kootenay Lake electric-ready ferry preparations, to accommodate the specific needs of hybrid-electric ferries and training personnel to handle the new technology.
Public response to the hybrid-electric ferry initiative has been largely positive, with many residents and environmental advocates expressing support for the move towards greener transportation. The new boats are seen as a tangible step toward reducing the environmental impact of one of the state’s most iconic transportation services. The project also highlights Washington State’s commitment to innovation and leadership in sustainable transportation, alongside global examples like Berlin's electric flying ferry that push the envelope in maritime transit.
However, the transition to hybrid-electric ferries is not without its challenges. Implementing new technology requires careful planning and coordination, including addressing potential technical issues and ensuring that the vessels meet all safety and operational standards. Additionally, there may be logistical challenges associated with integrating the new ferries into the existing fleet and managing the transition without disrupting service.
Despite these challenges, the updated plans for hybrid-electric boats represent a significant advancement in Washington State’s efforts to modernize its transportation system. The initiative reflects a growing trend among transportation agencies to embrace sustainable technologies and address the environmental impact of traditional transportation methods.
In summary, Washington State’s updated plans for hybrid-electric ferries mark a crucial step towards a more sustainable and environmentally friendly transportation network. By incorporating advanced hybrid-electric technology, the state aims to reduce carbon emissions, improve fuel efficiency, and align with its broader climate goals. While challenges remain, the initiative demonstrates a commitment to innovation and underscores the importance of transitioning to greener technologies in the quest for a more sustainable future.
Site C Dam Controversy highlights Peace River risks, BC Hydro claims, Indigenous rights under Treaty 8, environmental assessment findings, and potential impacts to agriculture and the Peace-Athabasca Delta across Alberta and the Northwest Territories.
Key Points
Debate over BC Hydro's Site C dam: clean energy vs Indigenous rights, Peace-Athabasca Delta impacts, and agriculture.
✅ Potential drying of Peace-Athabasca Delta and wildlife habitat
✅ Treaty 8 rights and First Nations legal challenges
✅ Loss of prime Peace Valley farmland; alternatives in renewables
One of the leading opponents of the Site C dam in northeastern B.C. is sharing her concerns with northerners this week.
Proponents of the Site C dam say it will be a cost-effective source of clean electricity, even as a major Alberta wind farm was scrapped elsewhere in Canada, and that it will be able to produce enough energy to power the equivalent of 450,000 homes per year in B.C. But a number of Indigenous groups and environmentalists are against the project.
Wendy Holm is an economist and agronomist who did an environmental assessment of the dam focusing on its potential impacts on agriculture.
On Tuesday she spoke at a town hall presentation in Fort Smith, N.W.T., organized by the Slave River Coalition. She is also speaking at an event in Yellowknife on Friday, as small modular reactors in Yukon receive study as a potential long-term option.
Worried about downstream impacts, Northern leaders urge action on Site C dam
"I learned that people outside of British Columbia are as concerned with this dam as we are," Holm said.
"There's just a lot of concern with what's happening on the Peace River and this dam and the implications for Alberta, where hydro's share has diminished in recent decades, and the Northwest Territories."
If completed, BC Hydro's Site C energy project will be the third dam on the Peace River in northeast B.C. and the largest public works project in B.C. history. The $10.7-billion project was approved by both the provincial and federal governments as B.C. moves to streamline clean energy permitting for future projects.
Amy Lusk, co-ordinator of the Slave River Coalition, said many issues were discussed at the town hall, but she also left with a sense of hope.
"I think sometimes in our little corner of the world, we are up against so much when it comes to industrial development and threats to our water," she said.
"To kind of take away that message of, this is not a done deal, and that we do have a few options in place to try and stop this and not to lose hope, I think was a very important message for the community."
Drying of the Peace-Athabasca Delta
Holm said her main concern for the Northwest Territories is how it could affect the Peace-Athabasca Delta. She said the two dams already on the river are responsible for two-thirds of the drying that's happening in the delta.
"These are very real issues and very present in the minds of northerners who want to stay connected to a traditional lifestyle, want to have access to those wild foods," she said.
Lusk said northerners are fed up with defending waters "time after time after time."
BC Hydro, however, said studies commissioned during the environmental assessment of Site C show the project will have no measurable effect on the delta, which is located 1,100 kilometres away.
Holm said the fight against the Site C dam is also important when it comes to First Nations treaty rights.
The West Moberly and Prophet River First Nations applied for an injunction to halt construction on Site C, as well as a treaty infringement lawsuit against the B.C. government. They argue the dam would cause irreparable harm to their territories and way of life, which are rights protected under Treaty 8.
Agricultural land
While the project is located in B.C., Holm said its impacts on prime horticulture land would also affect northerners, something that's important given issues of food security and nutrition.
"This is some of the best agriculture land in all of Canada," she said of the Peace Valley.
According to BC Hydro, around 2.6 million hectares of land in the Peace agricultural region would remain available for agricultural production while 3,800 hectares would be unavailable. It has also proposed a number of mitigation efforts, including a $20-million agricultural compensation fund.
Holm said renewable energy, including tidal energy for remote communities, will be cheaper and less destructive than the dam, and there's a connection between the dams on the Peace River and water sharing with the U.S.
"When you run out of water there's nothing else you can use. You can't use orange juice to irrigate your fields or to run your industries or to power your homes," she said.
EU Solar Impact on Electricity Prices highlights how rising solar PV penetration drives negative pricing, shifts peak hours, pressures wholesale markets, and challenges grid balancing, interconnection, and flexibility amid changing demand and renewables growth.
Key Points
Explains how rising solar PV cuts wholesale prices, shifts negative-price hours, and strains grid flexibility.
✅ Negative pricing events surge with higher solar penetration.
✅ Grid balancing, interconnectors, and flexibility become critical.
The latest EU electricity market report has confirmed the affect deeper penetration of solar is having on wholesale electricity prices more broadly.
The Quarterly Report on European Electricity Markets for the final three months of last year noted the number of periods of negative electricity pricing doubled from 2019, to almost 1,600 such events, as global renewables set new records in deployment across markets.
Having experienced just three negative price events in 2019, the Netherlands recorded almost 100 last year “amid a dramatic increase in solar PV capacity,” in the nation, according to the report.
Whilst stressing the exceptional nature of the Covid-19 pandemic on power consumption patterns, the quarterly update also noted a shift in the hours during which negative electric pricing occurred in renewables poster child Germany. Previously such events were most common at night, during periods of high wind speed and low demand, but 2020 saw a switch to afternoon negative pricing. “Thus,” stated the report, “solar PV became the main driver behind prices falling into negative territory in the German market in 2020, as Germany's solar boost accelerated, and also put afternoon prices under pressure generally.”
The report also highlighted two instances of scarce electricity–in mid September and on December 9–as evidence of the problems associated with accommodating a rising proportion of intermittent clean energy capacity into the grid, and called for more joined-up cross-border power networks, amid pushback from Russian oil and gas across the continent.
Rising solar generation–along with higher gas output, year on year–also helped the Netherlands generate a net surplus of electricity last year, after being a net importer “for many years.” The EU report also noted a beneficial effect of rising solar generation capacity on Hungary‘s national electricity account, and cited a solar “boom” in that country and Poland, mirroring rapid solar PV growth in China in recent years.
With Covid-19 falls in demand helping renewables generate more of Europe's electricity (39%) than fossil fuels (36%) for the first time, as renewables surpassed fossil fuels across Europe, the market report observed the 5% of the bloc's power produced from solar closed in on the 6% accounted for by hard coal. In the final three months of the year, European solar output rose 12%, year on year, to 18 TWh and “the increase was almost single-handedly driven by Spain,” the study added.
With coal and lignite-fired power plunging 22% last year across the bloc, it is estimated the European power sector reduced its carbon footprint 14% as part of Europe's green surge although the quarterly report warned cold weather, lower wind speeds and rising gas prices in the opening months of this year are likely to see carbon emissions rebound.
There was good news on the transport front, though, with the report stating the scale of the European “electrically-charged vehicle” fleet doubled in 2020, to 2 million, with almost half a million of the new registrations arriving in the final months of the year. That meant cars with plug sockets accounted for a remarkable 17% of new purchases in Q4, twice the proportion seen in China and a slice of the pie six times bigger than such products claimed in the U.S.
Canada Clean Electricity Regulations 2050 balance net-zero goals with grid reliability and affordability, setting emissions caps, enabling offset credits, and flexible provincial pathways, including support for non-grid facilities during the clean energy transition.
Key Points
A federal plan for a net-zero grid by 2050 with emissions caps, offsets, and flexible provincial compliance.
✅ Emissions cap targeting 181 Mt CO2 from the power sector by 2050
✅ Offset credits and annual limits enable compliance flexibility
✅ Support for remote, non-grid facilities and regional pathways
In December 2024, the Government of Canada announced a significant policy shift regarding its clean electricity objectives. The initial target to achieve a net-zero electricity grid by 2035 has been extended to 2050. This decision reflects the government's response to feedback from provinces and energy industry stakeholders, who expressed concerns about the feasibility of meeting the 2035 deadline.
Revised Clean Electricity Regulations
The newly finalized Clean Electricity Regulations (CER) outline the framework for Canada's transition to a net-zero electricity grid by 2050, advancing the goal of 100 per cent clean electricity nationwide.
Emissions Reduction Targets: The regulations set a cap on emissions from the electricity sector, targeting a reduction of 181 megatonnes of CO₂ by 2050. This is a decrease from the previous goal of 342 megatonnes, reflecting a more gradual approach to emissions reduction.
Flexibility Mechanisms: To accommodate the diverse energy landscapes across provinces, the CER introduces flexibility measures. These include annual emissions limits and the option to use offset credits, allowing provinces to tailor their strategies while adhering to national objectives.
Support for Non-Grid Connected Facilities: Recognizing the unique challenges of remote and off-grid communities, the regulations provide accommodations for certain non-grid connected facilities, ensuring that all regions can contribute to the national clean electricity goals.
Implications for Canada's Energy Landscape
The extension of the net-zero electricity target to 2050 signifies a strategic recalibration of Canada's energy policy. This adjustment acknowledges the complexities involved in transitioning to a clean energy future, including:
Grid Modernization: Upgrading the electrical grid to accommodate renewable energy sources and ensure reliability is a critical component of the transition, especially as Ontario's EV wave accelerates across the province.
Economic Considerations: Balancing environmental objectives with economic impacts is essential. The government aims to create over 400,000 clean energy jobs, fostering economic growth while reducing emissions, supported by ambitious EV goals in the transport sector.
Regional Variations: Provinces have diverse energy profiles and resources, and British Columbia's power supply challenges highlight planning constraints. The CER's flexibility mechanisms are designed to accommodate these differences, allowing for tailored approaches that respect regional contexts.
Public and Industry Reactions
The policy shift has elicited varied responses:
Environmental Advocates: Some environmental groups express concern that the extended timeline may delay critical climate action, while debates over Quebec's push for EV dominance underscore policy trade-offs. They emphasize the need for more ambitious targets to address the escalating impacts of climate change.
Industry Stakeholders: The energy sector generally welcomes the extended timeline, viewing it as a pragmatic approach that allows for a more measured transition, particularly amid criticism of the 2035 EV mandate in transportation policy. The flexibility provisions are particularly appreciated, as they provide the necessary leeway to adapt to evolving market and technological conditions.
Looking Forward
As Canada moves forward with the implementation of the Clean Electricity Regulations, the focus will be on:
Monitoring Progress: Establishing robust mechanisms to track emissions reductions and ensure compliance with the new targets.
Stakeholder Engagement: Continuing dialogue with provinces, industry, and communities to refine strategies and address emerging challenges, including coordination on EV sales regulations as complementary measures.
Innovation and Investment: Encouraging the development and deployment of clean energy technologies through incentives and support programs.
The extension of Canada's net-zero electricity target to 2050 represents a strategic adjustment aimed at achieving a balance between environmental goals and practical implementation considerations. The Clean Electricity Regulations provide a framework that accommodates regional differences and industry concerns, setting the stage for a sustainable and economically viable energy future.
