The Tennessee Valley Authority board made a commitment to cap its carbon emissions growth by 2020 in an effort to muzzle its contributions to climate change.
Proposals to find ways to increase renewable energy sources like solar power and to persuade customers to use less electricity — including by offering incentives — were approved, too.
The actions, which came as the agency recognizes its 75th anniversary, could mark a return to the leadership role TVA took in energy conservation in the 1970s but later dropped.
Nuclear power was listed among the "clean" energy sources that officials said would be looked to increasingly.
"The real objective is to reduce the carbon footprint," TVA CEO and President Tom Kilgore said after the meeting at the Marriott Shoals Hotel and Spa.
"Nuclear (power) does not produce carbon. I cannot argue that it doesn't produce radioactive waste that has to be dealt with."
But, with population growth in the region, large additional sources of energy are needed, he said, adding that nuclear power can provide that without putting more carbon in the air.
TVA, which is self-financing, is the largest public power producer in the country, providing virtually all of the electricity used in Tennessee and parts of six other states.
good move, but no nukes
John McFadden, head of the nonprofit Tennessee Environmental Council in Nashville, said in a phone interview that he was "glad" about TVA's turn toward energy conservation and cleaner power, a move that some utilities made several years ago.
"It's obvious it's something we've really needed to do for a long time," he said. "All you have to do is look at the mountaintops in the Great Smoky Mountains and see all the dead trees.
"And Knoxville is the asthma capital.Â…
"They should have been leading the country in this."
Nuclear power, however, should not be in the mix, he added.
"We have no long-term plan to deal with nuclear waste," he said.
"You can't sell a kilowatt hour of nuclear power for what it costs to produce it. That's why the federal government is having to subsidize the nuclear industry."
TVA is still carrying billions of dollars of debt from its first spurt of nuclear plant building that took place in the 1970s and 1980s, he said.
One new TVA goal is a reduction within five years — in part through customers' energy efficiency — of 1,400 megawatts of electricity use at peak times. This would be the equivalent of building a nuclear reactor to provide energy on days during the summer and winter when energy use spikes.
"We do think it's a goal that's very achievable," said Joe Hoagland, TVA vice president for energy efficiency and demand response.
Pilot programs could include financial incentives to buy energy-efficient appliances and lights.
Making the 2020 date to halt growth in carbon emissions was viewed as more challenging. Most of TVA's electricity comes from coal, which releases carbon that adds to climate change.
Weather remains a stumbling block on another front.
TVA official Bill McCollum said drought could continue to hamper hydroelectric energy generation at its dams this summer.
"We still need significantly more than the normal amount of rainfall between now and June," McCollum said.
When its clean, relatively inexpensive hydroelectric production falls behind, TVA must buy more costly electricity from other producers.
UK Wind Power Surpasses Gas as offshore wind and solar drive record electricity generation, National Grid milestones, and net zero progress, despite grid capacity bottlenecks, onshore planning reforms, demand from heat pumps and transport electrification.
Key Points
A milestone where wind turbines generated more UK electricity than gas, advancing progress toward a net zero grid.
✅ Offshore wind delivered the majority of UK wind generation
✅ Grid connection delays stall billions in green projects
✅ Planning reforms may restart onshore wind development
Wind turbines have generated more electricity than gas, as wind becomes the main source for the first time in the UK.
In the first three months of this year a third of the country's electricity came from wind farms, as the UK set a wind generation record that underscored the trend, research from Imperial College London has shown.
National Grid has also confirmed that April saw a record period of solar energy generation, and wind and solar outproduced nuclear in earlier milestones.
"There are still many hurdles to reaching a completely fossil fuel-free grid, but wind out-supplying gas for the first time is a genuine milestone event," said Iain Staffell, energy researcher at Imperial College and lead author of the report.
The research was commissioned by Drax Electrical Insights, which is funded by Drax energy company.
The majority of the UK's wind power has come from offshore wind farms, and the country leads the G20 for wind's electricity share according to recent analyses. Installing new onshore wind turbines has effectively been banned since 2015 in England.
Under current planning rules, companies can only apply to build onshore wind turbines on land specifically identified for development in the land-use plans drawn up by local councils. Prime Minister Rishi Sunak agreed in December to relax these planning restrictions to speed up development.
Scientists say switching to renewable power is crucial to curb the impacts of climate change, which are already being felt, including in the UK, which last year recorded its hottest year since records began.
Solar and wind have seen significant growth in the UK, with wind surpassing coal in 2016 as a milestone. In the first quarter of 2023, 42% of the UK's electricity came from renewable energy, with 33% coming from fossil fuels like gas and coal.
But BBC research revealed on Thursday that billions of pounds' worth of green energy projects are stuck on hold due to delays with getting connections to the grid, as peak power prices also climbed amid system pressures.
Some new solar and wind sites are waiting up to 10 to 15 years to be connected because of a lack of capacity in the electricity system.
And electricity only accounts for 18% of the UK's total power needs. There are many demands for energy which electricity is not meeting, such as heating our homes, manufacturing and transport.
Currently the majority of UK homes use gas for their heating - the government is seeking to move households away from gas boilers and on to heat pumps which use electricity.
Consumers Energy Virtual Energy Coaching connects Michigan small businesses with remote efficiency experts to cut utility costs, optimize energy usage, and access rebates and incentives, delivering safe COVID-19-era support and long-term savings through tailored assessments.
Key Points
A remote coaching service helping small businesses improve energy efficiency, access rebates, and cut utility costs.

"By developing lasting customer relationships and delivering consistent solutions through conversation, the Energy Coaching Program offers the next level of support for small business customers," said Hollie Whitmire, Franklin Energy program manager. "Energy coaching is suitable for all small businesses, but it's ideal for businesses that are new to energy efficiency or for those that have had low engagement with energy efficiency offerings and emerging new utility rate designs in years past."
Through a series of three calls, eligible small businesses can speak with an energy coach to help them connect to the right program offering available through Consumers Energy's energy efficiency programs for businesses, including demand response models like the Ontario Peak Perks program that support load management. From answering questions to reviewing energy usage, conducting assessments, identifying savings opportunities, and more, the energy coach is available to help small businesses put money back into their pocket now, when it matters most.
"Consumers Energy is committed to helping Michigan's small business community prosper, now more than ever, with examples such as Entergy's COVID-19 relief fund underscoring industry support," said Lauren Youngdahl Snyder, Consumers Energy's vice president of customer experience. "We are excited to work with Franklin Energy to develop an innovative solution for our small business customers. The Virtual Energy Coaching Service lets us engage our customers in a safe and effective manner, as seen with utilities waiving fees in Texas during the crisis, and has the potential to last even past the COVID-19 pandemic."
Japan Electricity Crunch exposes vulnerabilities in a liberalised power market as LNG shortages, JEPX price spikes, snow-hit solar, and weak hedging strain energy security and retail providers amid cold snap demand and limited reserve capacity.
Key Points
A winter demand shock and LNG shortfalls sent JEPX to records, exposing gaps in hedging, data, and energy security.
✅ JEPX wholesale prices spiked to an all-time high
✅ LNG inventories and procurement proved insufficient
✅ Snow disabled solar; new entrants lacked hedging
Japan's worst electricity crunch since the aftermath of the Fukushima crisis has exposed vulnerabilities in the country's recently liberalised power market, although some of the problems appear self-inflicted.
Power prices in Japan hit record highs last month, mirroring UK peak power prices during tight conditions, as a cold snap across northeast Asia prompted a scramble for supplies of liquefied natural gas (LNG), a major fuel for the country's power plants. Power companies urged customers to ration electricity to prevent blackouts, although no outages occurred.
The crisis highlighted how many providers were unprepared for such high demand. Experts say LNG stocks were not topped up ahead of winter and snow disabled solar power farms, while China's power woes strained solar supply chains.
The hundreds of small power companies that sprang up after the market was opened in 2016 have struggled the most, saying the government does not disclose the market data they need to operate. The companies do not have their own generators, instead buying electricity on the wholesale market.
Prices on the Japan Electric Power Exchange (JEPX) hit a record high of 251 yen ($2.39) per kilowatt hour in January, equating to $2,390 per megawatt hour of electricity, above record European price surges seen recently and the highest on record anywhere in the world. One megawatt hour is roughly what an average home in the U.S. would consume over 35 days.
But the vast majority of the new, smaller companies are locked into low, fixed rates they set to lure customers from bigger players, crushing them financially during a price spike like the one in January.
More than 50 small power providers wrote on Jan. 18 to Japan's industry minister, Hiroshi Kajiyama, who oversees the power sector, asking for more accessible data on supply and demand, reserve capacity and fuel inventories.
"By organising and disclosing this information, retail electricity providers will be able to bid at more appropriate prices," said the companies, led by Looop Co.
They also called on Kajiyama to require transmission and distribution companies to pass on some of the unexpected profits from price spikes to smaller operators.
The industry ministry said it had started releasing more timely market data, and is reviewing the cause of the crunch and considering changes, echoing calls by Fatih Birol to keep electricity options open amid uncertainty.
Japan reworked its power markets after the Fukushima nuclear disaster in 2011, liberalizing the sector in 2016 while pushing for more renewables.
But Japan is still heavily reliant on LNG and coal, and only four of 33 nuclear reactors are operating. The power crisis has led to growing calls to restart more reactors.
Kazuno Power, a small retail provider controlled by a municipality of the same name in northern Japan, where abundant renewable energy is locally produced, buys electricity from hydropower stations and JEPX.
During the crunch, the company had to pay nearly 10 times the usual price, Kazuno Power president Takao Takeda said in an interview. Like most other new providers, it could not pass on the costs, lost money, and folded. The local utility has taken over its customers.
"There is a contradiction in the current system," Takeda said. "We are encouraged to locally produce power for local consumption as well as use more renewable energy, but prices for these power supplies are linked to wholesale prices, which depend on the overall power supply."
The big utilities, which receive most of their LNG on long-term contracts, blamed the power shortfall on a tight spot market and glitches at generation units.
"We were not able to buy as much supply as we wanted from the spot market because of higher demand from South Korea and China, where power cuts have tightened supply," Kazuhiro Ikebe, the head of the country's electricity federation, said recently.
Ikebe is also president of Kyushu Electric Power, which supplies the southern island of Kyushu.
Utilities took extreme measures - from burning polluting fuel oil in coal plants to scavenging the dregs from empty LNG tankers - to keep the grid from breaking down.
"There is too much dependence on JEPX for procurement," said Bob Takai, the local head of European Energy Exchange, where electricity pricing reforms are being discussed, and which started offering Japan power futures last year. He added that new entrants were not hedging against sharp price moves.
Three people, who requested anonymity because of the sensitivity of the matter, were more blunt. One called the utilities arrogant in assuming they could find LNG cargoes in a pinch. Prices were already rising as China snapped up supplies, the sources noted.
"You had volatility caused by people saying 'Oh, well, demand is going to be weak because of coronavirus impacts' and then saying 'we can rely more on solar than in the past,' but solar got snowed out," said a senior executive from one generator. "We have a problem of who is charge of energy security in Japan."
Inventories of LNG, generally about two weeks worth of supplies, were also not topped up enough to prepare for winter, a market analyst said.
The fallout from the crunch has become more apparent in recent days, with new power companies like Rakuten Inc suspending new sales and Tokyo Gas, along with traditional electricity utilities, issuing profit downgrades or withdrawing their forecasts.
Although prices have fallen sharply as temperatures warmed up slightly and more generation units have come back online, the power generator executive said, "we are not out of the woods yet."
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.
BC Hydro Holiday Energy Saving Tips highlight electricity usage trends and power conservation during Christmas cooking. Use efficient appliances, lower the thermostat, and track consumption with MyHydro to reduce bills while hosting guests.
Key Points
Guidelines from BC Hydro to cut holiday electricity usage via efficient cooking, smart thermostats, and MyHydro tracking.
✅ Use microwave, toaster oven, or slow cooker to save power.
✅ Batch-bake cookies and pies to minimize oven cycles.
✅ Set thermostat to 18 C and monitor use with MyHydro.
BC Hydro is reminding British Columbians to conserve power over the holidays after a report commissioned by the utility found the arrival of guests for Christmas dinner results in a 15% increase in electricity usage, and it expects holiday usage to rise as gatherings ramp up.
Cooking appears to be the number one culprit for the uptick in peoples’ hydro bills. According to BC Hydro press release, British Columbians use about 8,000 megawatt hours more of electricity by mid-day Christmas — that's about 1.5 million turkeys roasted in electric ovens — while Ontario electricity demand shifted as people stayed home during the pandemic. article continues below
About 95% of British Columbians said they would make meals at home from scratch over the holiday season, mirroring the uptick in residential electricity use observed during the pandemic. The survey found that inviting friends or family over trumped any plans people had to buy pre-made meals or order take-out. Six in 10 respondents said they would also rather bake holiday treats than pick them up pre-made from the store.
The survey also showed people in B.C. are taking steps to reduce their electricity usage, echoing earlier findings that many British Columbians changed daily electricity habits during the pandemic. When participants were asked whether they were conscious of how much electricity they used when visiting friends or family, 80% said they would be taking steps to limit their usage.
And while cooking meals from scratch over the holidays may contribute to a spike in a person's electricity bill, some studies have found that, when comparing their overall environmental impact against that of ready-made meals, a roasted dinner has a lower negative impact.
Still, there are many ways to improve your energy efficiency and save some money over the holiday season, and conserving can also help the grid during events like the recent atypical storm response noted by BC Hydro. BC Hydro recommends:
• using smaller appliances whenever possible, such as a microwave, crockpot or toaster oven as they use less than half the power of a regular electric oven;
• baking cookies or pies in batches to save energy;
• turning down the household thermostat to 18 C when possible to reduce costs during peak hydro rates where applicable;
• and tracking how much electricity you use through the MyHydro tool alongside potential time-of-use rates for smarter scheduling
Europe 2023 Energy Shortfall underscores how weak hydro and nuclear offset record solar and wind, tightening grids as natural gas supplies shrink and demand rebounds, heightening risks of electricity shortages across key economies.
Key Points
A regional gap as weak hydro and nuclear offset record solar and wind, straining supply as gas stays tight.
✅ Hydro and nuclear output fell sharply in early 2023
✅ Record solar and wind could not offset the deficit
✅ Industrial demand rebound pressures limited gas supplies
Shortfalls in Europe's hydro and nuclear output have more than offset record electricity generation from wind and solar power sites over the first quarter of 2023, leaving the region vulnerable to acute energy shortages for the second straight year.
European countries fast-tracked renewable energy capacity development in 2022 in the wake of Russia's invasion of Ukraine last February, which upended natural gas flows to the region and sent power prices soaring.
Europe lifted renewable energy supply capacity by a record 57,290 megawatts in 2022, or by nearly 9%, according to the International Energy Agency (IRENA), amid a scramble to replace imported Russian gas with cleaner, home-grown energy.
However, steep drops in both hydro and nuclear output - two key sources of non-emitting energy - mean Europe's power producers have limited ways to lift overall electricity generation, as the region is losing nuclear power at a critical moment, just as the region's economies start to reboot after last year's energy shock.
POWER PLATEAU Europe's total electricity generation over the first quarter of 2023 hit 1,213 terawatt hours, or roughly 6.4% less than during the same period in 2022, according to data from think tank Ember.
At the same time, European power hits records during extreme heat as plants struggle to cool, exacerbating supply risks.
As Europe's total electricity demand levels were in post-COVID-19 expansion mode in early 2022 before Russia's so-called special operation sent power costs to record highs amid debates over how electricity is priced in Europe, it makes sense that overall electricity use was comparatively stunted in early 2023.
However, efforts are now underway to revive activity at scores of European factories, industrial plants and production lines that were shuttered or curtailed in 2022, so Europe's collective electricity consumption totals are set to trend steadily higher over the remainder of 2023.
With Russian natural gas unavailable in the previous quantities due to sanctions and supply issues, Europe's power producers will need to deploy alternative energy sources, including renewables poised to eclipse coal globally, to feed that increase in power demand.
And following the large jump in renewable capacity brought online in 2022, utilities can deploy more low-emissions energy than ever before across Europe's electricity grids.
