As of the end of 2007, China had 158 windfarms comprising 6,469 wind turbines and a total installed capacity of 5,906 megawatts (MW) operating in mainland China. Last year, China added 3,304 MW of wind power, an increase of 147.1% compared with 1,337 MW added in 2006.
Among the newly added market share, Chinese products made up 55.9%, surpassing foreign companies for the first time, according the Second China (Shanghai) International Wind Energy Exhibition & Symposium 2008 (CWEE2008) held at the end of April in Shanghai.
China has a theoretical wind-energy reserve of 3.2 terawatts (1 terawatt
1,024 gigawatts) at 10 meters in height. The total exploitable terrestrial wind energy is estimated at 800 gigawatts (GW) at 50 meters high, and the actual exploitable wind energy offshore is about 150 GW at 50 meters high. Based on the current growth trend, the total installed capacity of wind power in China is expected to reach 15 GW-20 GW in 2010, and 80 GW-100 GW in 2020.
ITER Nuclear Fusion advances tokamak magnetic confinement, heating deuterium-tritium plasma with superconducting magnets, targeting net energy gain, tritium breeding, and steam-turbine power, while complementing laser inertial confinement milestones for grid-scale electricity and 2025 startup goals.
Key Points
ITER Nuclear Fusion is a tokamak project confining D-T plasma with magnets to achieve net energy gain and clean power.
✅ Tokamak magnetic confinement with high-temp superconducting coils
✅ Deuterium-tritium fuel cycle with on-site tritium breeding
✅ Targets net energy gain and grid-scale, low-carbon electricity
It sounds like the stuff of dreams: a virtually limitless source of energy that doesn’t produce greenhouse gases or radioactive waste. That’s the promise of nuclear fusion, often described as the holy grail of clean energy by proponents, which for decades has been nothing more than a fantasy due to insurmountable technical challenges. But things are heating up in what has turned into a race to create what amounts to an artificial sun here on Earth, one that can provide power for our kettles, cars and light bulbs.
Today’s nuclear power plants create electricity through nuclear fission, in which atoms are split, with next-gen nuclear power exploring smaller, cheaper, safer designs that remain distinct from fusion. Nuclear fusion however, involves combining atomic nuclei to release energy. It’s the same reaction that’s taking place at the Sun’s core. But overcoming the natural repulsion between atomic nuclei and maintaining the right conditions for fusion to occur isn’t straightforward. And doing so in a way that produces more energy than the reaction consumes has been beyond the grasp of the finest minds in physics for decades.
But perhaps not for much longer. Some major technical challenges have been overcome in the past few years and governments around the world have been pouring money into fusion power research as part of a broader green industrial revolution under way in several regions. There are also over 20 private ventures in the UK, US, Europe, China and Australia vying to be the first to make fusion energy production a reality.
“People are saying, ‘If it really is the ultimate solution, let’s find out whether it works or not,’” says Dr Tim Luce, head of science and operation at the International Thermonuclear Experimental Reactor (ITER), being built in southeast France. ITER is the biggest throw of the fusion dice yet.
Its $22bn (£15.9bn) build cost is being met by the governments of two-thirds of the world’s population, including the EU, the US, China and Russia, at a time when Europe is losing nuclear power and needs energy, and when it’s fired up in 2025 it’ll be the world’s largest fusion reactor. If it works, ITER will transform fusion power from being the stuff of dreams into a viable energy source.
Constructing a nuclear fusion reactor ITER will be a tokamak reactor – thought to be the best hope for fusion power. Inside a tokamak, a gas, often a hydrogen isotope called deuterium, is subjected to intense heat and pressure, forcing electrons out of the atoms. This creates a plasma – a superheated, ionised gas – that has to be contained by intense magnetic fields.
The containment is vital, as no material on Earth could withstand the intense heat (100,000,000°C and above) that the plasma has to reach so that fusion can begin. It’s close to 10 times the heat at the Sun’s core, and temperatures like that are needed in a tokamak because the gravitational pressure within the Sun can’t be recreated.
When atomic nuclei do start to fuse, vast amounts of energy are released. While the experimental reactors currently in operation release that energy as heat, in a fusion reactor power plant, the heat would be used to produce steam that would drive turbines to generate electricity, even as some envision nuclear beyond electricity for industrial heat and fuels.
Tokamaks aren’t the only fusion reactors being tried. Another type of reactor uses lasers to heat and compress a hydrogen fuel to initiate fusion. In August 2021, one such device at the National Ignition Facility, at the Lawrence Livermore National Laboratory in California, generated 1.35 megajoules of energy. This record-breaking figure brings fusion power a step closer to net energy gain, but most hopes are still pinned on tokamak reactors rather than lasers.
In June 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) reactor maintained a plasma for 101 seconds at 120,000,000°C. Before that, the record was 20 seconds. Ultimately, a fusion reactor would need to sustain the plasma indefinitely – or at least for eight-hour ‘pulses’ during periods of peak electricity demand.
A real game-changer for tokamaks has been the magnets used to produce the magnetic field. “We know how to make magnets that generate a very high magnetic field from copper or other kinds of metal, but you would pay a fortune for the electricity. It wouldn’t be a net energy gain from the plant,” says Luce.
One route for nuclear fusion is to use atoms of deuterium and tritium, both isotopes of hydrogen. They fuse under incredible heat and pressure, and the resulting products release energy as heat
The solution is to use high-temperature, superconducting magnets made from superconducting wire, or ‘tape’, that has no electrical resistance. These magnets can create intense magnetic fields and don’t lose energy as heat.
“High temperature superconductivity has been known about for 35 years. But the manufacturing capability to make tape in the lengths that would be required to make a reasonable fusion coil has just recently been developed,” says Luce. One of ITER’s magnets, the central solenoid, will produce a field of 13 tesla – 280,000 times Earth’s magnetic field.
The inner walls of ITER’s vacuum vessel, where the fusion will occur, will be lined with beryllium, a metal that won’t contaminate the plasma much if they touch. At the bottom is the divertor that will keep the temperature inside the reactor under control.
“The heat load on the divertor can be as large as in a rocket nozzle,” says Luce. “Rocket nozzles work because you can get into orbit within minutes and in space it’s really cold.” In a fusion reactor, a divertor would need to withstand this heat indefinitely and at ITER they’ll be testing one made out of tungsten.
Meanwhile, in the US, the National Spherical Torus Experiment – Upgrade (NSTX-U) fusion reactor will be fired up in the autumn of 2022, while efforts in advanced fission such as a mini-reactor design are also progressing. One of its priorities will be to see whether lining the reactor with lithium helps to keep the plasma stable.
Choosing a fuel Instead of just using deuterium as the fusion fuel, ITER will use deuterium mixed with tritium, another hydrogen isotope. The deuterium-tritium blend offers the best chance of getting significantly more power out than is put in. Proponents of fusion power say one reason the technology is safe is that the fuel needs to be constantly fed into the reactor to keep fusion happening, making a runaway reaction impossible.
Deuterium can be extracted from seawater, so there’s a virtually limitless supply of it. But only 20kg of tritium are thought to exist worldwide, so fusion power plants will have to produce it (ITER will develop technology to ‘breed’ tritium). While some radioactive waste will be produced in a fusion plant, it’ll have a lifetime of around 100 years, rather than the thousands of years from fission.
At the time of writing in September, researchers at the Joint European Torus (JET) fusion reactor in Oxfordshire were due to start their deuterium-tritium fusion reactions. “JET will help ITER prepare a choice of machine parameters to optimise the fusion power,” says Dr Joelle Mailloux, one of the scientific programme leaders at JET. These parameters will include finding the best combination of deuterium and tritium, and establishing how the current is increased in the magnets before fusion starts.
The groundwork laid down at JET should accelerate ITER’s efforts to accomplish net energy gain. ITER will produce ‘first plasma’ in December 2025 and be cranked up to full power over the following decade. Its plasma temperature will reach 150,000,000°C and its target is to produce 500 megawatts of fusion power for every 50 megawatts of input heating power.
“If ITER is successful, it’ll eliminate most, if not all, doubts about the science and liberate money for technology development,” says Luce. That technology development will be demonstration fusion power plants that actually produce electricity, where advanced reactors can build on decades of expertise. “ITER is opening the door and saying, yeah, this works – the science is there.”
Ontario Industrial Electricity Pricing Reforms aim to cut regulatory burden for industrial ratepayers through an energy concierge service, IESO billing reviews, GA estimation enhancements, clearer peak demand data, and contract cost savings.
Key Points
Measures to reduce industrial power costs via an energy concierge, IESO and GA reviews, and better peak demand data.
✅ Energy concierge eases pricing and connection inquiries
✅ IESO to simplify bills and refine GA estimation
✅ Real-time peak data and contract savings under review
Ontario's government is pursuing burden reduction measures for industrial electricity ratepayers, including legislation to lower rates to help businesses compete, and stimulate growth and investment.
Over the next year, Ontario will help industrial electricity ratepayers focus on their businesses instead of their electricity management practices by establishing an energy concierge service to provide businesses with better customer service and easier access to information about electricity pricing and changes for electricity consumers as well as connection processes.
Ontario is also tasking the Independent Electricity System Operator (IESO) to review and report back on its billing, settlement and customer service processes, building on initiatives such as electricity auctions that aim to reduce costs.
Improve and simplify industrial electricity bills, including clarifying the recovery rate that affects charges;
Review how the monthly Global Adjustment (GA) charge is estimated and identify potential enhancements related to cost allocation across classes; and,
Improve peak demand data publication processes and assess the feasibility of using real-time data to determine the factors that allocate GA costs to consumers.
Further, as part of the government's continued effort to finding efficiencies in the electricity system, Ontario is also directing IESO to review generation contracts to find opportunities for cost savings.
These measures are based on industry feedback received during extensive industrial electricity price consultations held between April and July 2019, which underscored how high electricity rates have impacted factories across the province.
"Our government is focused on finding workable electricity pricing solutions that will provide the greatest benefit to Ontario," said Greg Rickford, Minister of Energy, Northern Development and Mines. "Reducing regulatory burden on businesses can free up resources that can then be invested in areas such as training, new equipment and job creation."
The government is also in the process of developing further changes to industrial electricity pricing policy, amid planned rate increases announced by the OEB, informed by what was heard during the industrial electricity price consultations.
"It's important that we get this right the first time," said Minister Rickford. "That's why we're taking a thoughtful approach and listening carefully to what businesses in Ontario have to say."
Helping industrial ratepayers is part of the government's balanced and prudent plan to build Ontario together through ensuring our province is open for business and building a more transparent and accountable electricity system.
NL Hydro electricity credit delivers a one-time on-bill rebate from the rate stabilization fund, linked to oil prices and the Holyrood plant, via the Public Utilities Board, with payment deferrals and interest relief for customers.
Key Points
A one-time on-bill credit from the rate stabilization fund to cut power costs as oil prices remain low.
✅ One-time on-bill credit via the Public Utilities Board
✅ Funded by surplus in the rate stabilization fund
✅ Deferrals and 15 months interest assistance available
Most people who pay electricity bills will get a one-time credit as early as July.
The provincial government on Thursday outlined a new directive to the Public Utilities Board to provide a one-time credit for customers whose electricity rates are affected by the price of oil, part of an effort to shield ratepayers from Muskrat Falls overruns through recent agreements.
Electricity customers who are not a part of the Labrador interconnected system, including those using diesel on the north coast of Labrador, will receive the credit.
The credit, announced at a press conference Thursday morning, will come from the rate stabilization fund and comes as many customers have begun paying for Muskrat Falls on their bills, which has an estimated surplus of about $50 million because low oil prices mean NL Hydro has spent less on fuel for the Holyrood thermal generating station.
Normally a surplus would be paid out over a year, but customers this year will get the credit in a lump sum, as early as July, with the amount varying based on electricity usage.
"Given the difficult times many are finding themselves in, we believe an upfront, one-time on-bill credit would be much more helpful for customers than a small monthly decrease over the next 12 months," said Natural Resources Minister Siobhan Coady at the provincial government's announcement Thursday morning.
"We have requested that the board of commissioners of the Public Utilities Board, even as Nova Scotia's regulator approved a 14% increase recently, adopt a policy so that a credit will be dispersed immediately," Ball said.
"This is to help people when they need it the most.… We're doing what we can to support you."
The provincial government estimates someone whose power costs an average of $200 a month would get a one-time credit of about $130. Details of the plan will be left to the PUB.
Deferred payments allowed Ball said the credit will make a "significant impact" on customers' July bills.
Both businesses and residential customers will also be able to defer payments, similar to Alberta's deferral program that shifted costs for unpaid bills, with up to $2.5 million in interest being waived on overdue accounts. Customers will be required to make agreed-upon monthly payments to their account, and there will be interest assistance for 15 months, beginning June 1.
Coady said customers can renegotiate their bills and defer payments, with the province picking up the tab for the interest.
"You can speak to a customer service agent and they will make accommodations, but you have to continue to make some version of a monthly payment," Coady
"The interest that may be accrued is going to be paid for by the provincial government, so if you're a business, a person, and you're having difficulty and you can't make what I would say is your normal payment, call your utility, make some arrangements."
Labrador's interconnected grid isn't affected by the price of oil, but those customers can take advantage of the interest relief.
Relief policies already put in place during the pandemic, like not disconnecting customers and providing options for more flexible bill payments, will continue, as utilities such as Hydro One reconnecting customers demonstrate in Ontario.
Credit not enough to support customers: PCs While Ball said his government is doing what they can to help ratepayers, the opposition doesn't believe the announcement does enough to support those who need it.
Tony Wakeham, the Progressive Conservative MHA for Stephenville-Port au Port, said in a statement Thursday the credit simply gives people's money back to them, after the NL Consumer Advocate called an 18% rate hike unacceptable, and Newfoundland Power stands to benefit.
"The Liberal government would like ratepayers to believe that they are getting electricity rate relief, but in reality, customers would have been entitled to receive the value of this credit anyway over a 12-month period. Furthermore, in providing a one-time credit, Newfoundland Power will also be able to collect an administrative fee, adding to their revenues," Wakeham said in the statement.
"People and businesses in this province are struggling to pay their utility bills, and the Liberal government should help them by putting extra money into their pockets, not by recycling an already existing program to the benefit of a large corporation."
Wakeham called on government to direct the PUB to lower Newfoundland Power's guaranteed rate of return to give cash refunds to customers, and for Newfoundland Power to waive its fees.
Offshore Wind Cost Competitiveness is rising as larger turbines boost megawatt output, cut LCOE, and trim maintenance and installation time, enabling projects in New England to rival natural gas pricing while scaling reliably.
Key Points
It describes how larger offshore turbines lower LCOE and O&M, making U.S. projects price competitive with natural gas.
✅ Larger turbines boost MW output and reduce LCOE.
✅ Lower O&M and faster installation cut lifecycle costs.
✅ Competes with gas in New England bids, per BNEF.
Massive offshore wind turbines keep getting bigger, as projects like the biggest UK offshore wind farm come online, and that’s helping make the power cheaper — to the point where developers say new projects in U.S. waters can compete with natural gas.
The price “is going to be a real eye-opener,” said Bryan Martin, chairman of Deepwater Wind LLC, which won an auction in May to build a 400-megawatt wind farm southeast of Rhode Island.
Deepwater built the only U.S. offshore wind farm, a 30-megawatt project that was completed south of Block Island in 2016. The company’s bid was selected by Rhode Island the same day that Massachusetts picked Vineyard Wind to build an 800-megawatt wind farm in the same area, while international investors such as Japanese utilities in UK projects signal growing confidence.

Bigger turbines that make more electricity have cut the cost per megawatt by about half, a trend aided by higher-than-expected wind potential in many markets, said Tom Harries, a wind analyst at Bloomberg New Energy Finance. That also reduces maintenance expenses and installation time. All of this is helping offshore wind vie with conventional power plants.
“You could not build a thermal gas plant in New England for the price of the wind bids in Massachusetts and Rhode Island,” Martin said Friday at the U.S. Offshore Wind Conference in Boston. “It’s very cost-effective for consumers.”
The Massachusetts project could be about $100 to $120 a megawatt hour, according to a February estimate from Harries, though recent UK price spikes during low wind highlight volatility. The actual prices there and in Rhode Island weren’t disclosed.
For comparison, a new U.S. combine-cycle gas turbine ranges from $40 to $60 a megawatt-hour, and a new coal plant is $67 to $113, according to BNEF data.
A new power plant in land-constrained New England would probably be higher than that, and during winter peaks the region has seen record oil-fired generation in New England that underscores reliability concerns. More importantly, gas plants get a significant portion of their revenue from being able to guarantee that power is always available, something wind farms can’t do, said William Nelson, a New York-based analyst with BNEF. Looking only at the price at which offshore turbines can deliver electricity is a “narrow mindset,” he said.
Iran Power Outage Protests surge as electricity blackouts, drought, and a looming heat wave spark unrest in Tehran, Shiraz, and more, with chants against leadership, strikes, and sanctions-driven economic pressures mounting.
Key Points
Protests across Iran over blackouts, drought, and economic strain challenge authorities and demand accountability.
✅ Rolling blackouts blamed on drought, heat wave, and surging demand.
✅ Chants target leadership amid strikes and wage, water shortages.
✅ Legitimacy questioned after low-turnout election and sanctions.
There have been protests in a number of cities in Iran amid rising public anger over widespread electricity blackouts.
Videos on social media appeared to show crowds in Shar-e Rey near Tehran, Shiraz, Amol and elsewhere overnight.
Some people can be heard shouting "Death to the dictator" and "Death to Khamenei" - a reference to Supreme Leader Ayatollah Ali Khamenei.
The government has apologised for the blackouts, which it has blamed on a severe drought and high demand.
Elsewhere, similar outages have had political repercussions, as a widespread power outage in Taiwan prompted a minister's resignation earlier this year.
President Hassan Rouhani explained in televised remarks on Tuesday morning that the drought meant most of the country's hydroelectric power plants were not operating, placing more pressure on thermal power plants, and that electricity consumption had surged as people used air conditioning to cope with the intense summer heat.
"I apologise to our dear people who have faced problems and suffering in the past few days and I urge them to co-operate [by cutting their electricity use]. People complain about power outages and they are right," Mr Rouhani said.
A video that has gone viral in recent days shows a woman complaining about the blackouts and corruption at a government office in the northern city of Gorgan and demanding that her comments be conveyed to "higher-ups like Mr Rouhani". "The only thing you have done is forcing hijab on us," she shouts.
The president has promised that the government will seek to resolve the problems within the next two or three weeks.
However, a power sector spokesman warned on Monday that consumption was exceeding the production capacity of Iran's power plants by 11GW, and said a "looming heat wave" could make the situation worse, as seen in Iraq's summer electricity crunch this year.
Iranians have also been complaining about water shortages and the non-payment of wages by some local authorities, while thousands of people working in Iran's oil industry have been on strike over pay and conditions, as officials discuss further energy cooperation with Iraq to ease supply pressures.
There was already widespread discontent at government corruption and the economic hardship caused by sanctions that were reinstated when the US abandoned a nuclear deal with Iran three years ago, even as Iran supplies about 40% of Iraq's electricity through cross-border sales.
Analysts say that after the historically low turnout in last month's presidential election, when more than half of the eligible voters stayed at home, the government is facing a serious challenge to its legitimacy.
Mr Rouhani will be succeeded next month by Ebrahim Raisi, a hard-line cleric close to Ayatollah Khamenei who won 62% of the vote after several prominent contenders were disqualified, while Iran finalizes power grid deals with Iraq to bolster regional ties.
The 60-year-old former judiciary chief has presented himself as the best person to combat corruption and solve Iran's economic problems, including ambitions to transmit electricity to Europe as a regional power hub.
But many Iranians and human rights activists have pointed to his human rights record, accusing him of playing a role in the executions of thousands of political prisoners in the 1980s and in the deadly crackdowns on mass anti-government protests in 2009 and 2019.
Alberta Solar Power is accelerating as renewable energy investment, PPAs, and utility-scale projects expand the grid, with independent power producers and foreign capital outperforming AESO forecasts in oil-and-gas-rich markets across Alberta and Calgary.
Key Points
Alberta Solar Power is a fast-growing provincial market, driven by PPAs and private investment, outpacing AESO forecasts.
✅ Utility-scale projects and PPAs expand capacity beyond AESO outlooks
✅ Private and foreign capital drive independent power producers
✅ Costs near $70/MWh challenge >$100/MWh assumptions
Solar power is beating expectations in oil and gas rich Alberta, where the renewable energy source is poised to expand dramatically amid a renewable energy surge in the coming years as international power companies invest in the province.
Fresh capital is being deployed in the Alberta’s electricity generation sector for both renewable and natural gas-fired power projects after years of uncertainty caused by changes and reversals in the province’s power market, said Duane Reid-Carlson, president of power consulting firm EDC Associates, who advises renewable power developers on electric projects in the province.
“From the mix of projects that we see in the queue at the (Alberta Electric System Operator) and the projects that have been announced, Alberta, a powerhouse for both green energy and fossil fuels, has no shortage of thermal and renewable projects,” Reid-Carlson said, adding that he sees “a great mix” of independent power companies and foreign firms looking to build renewable projects in Alberta.
Alberta is a unique power market in Canada because its electricity supply is not dominated by a Crown corporation such as BC Hydro, Hydro One or Hydro Quebec. Instead, a mix of private-sector companies and a few municipally owned utilities generate electricity, transmit and distribute that power to households and industries under long-term contracts.
Last week, Perimeter Solar Inc., backed by Danish solar power investor Obton AS, announced Sept. 30 that it had struck a deal to sell renewable energy to Calgary-based pipeline giant TC Energy Corp. with 74.25 megawatts of electricity from a new 130-MW solar power project immediately south of Calgary. Neither company disclosed the costs of the transaction or the project.
“We are very pleased that of all the potential off-takers in the market for energy, we have signed with a company as reputable as TC Energy,” Obton CEO Anders Marcus said in a release announcing the deal, which it called “the largest negotiated energy supply agreement with a North American energy company.”
Perimeter expects to break ground on the project, which will more than double the amount of solar power being produced in the province, by the end of this year.
A report published Monday by the Energy Information Administration, a unit of the U.S. Department of Energy, estimated that renewable energy powered 3 per cent of Canada’s energy consumption in 2018.
Between the Claresholm project and other planned solar installations, utility companies are poised to install far more solar power than the province is currently planning for, even as Alberta faces challenges with solar expansion today.
University of Calgary adjunct professor Blake Shaffer said it was “ironic” that the Claresholm Solar project was announced the exact same day as the Alberta Electric System Operator released a forecast that under-projected the amount of solar in the province’s electric grid.
The power grid operator (AESO) released its forecast on Sept. 30, which predicted that solar power projects would provide just 1 per cent of Alberta’s electricity supply by 2030 at 231 megawatts.
Shaffer said the AESO, which manages and operates the province’s electricity grid, is assuming that on a levelized basis solar power will need a price over $100 per megawatt hour for new investment. However, he said, based on recent solar contracts for government infrastructure projects, the cost is closer to $70 MW/h.
Most forecasting organizations like the International Energy Agency have had to adjust their forecasts for solar power adoption higher in the past, as growth of the renewable energy source has outperformed expectations.
Calgary-based Greengate Power has also proposed a $500-million, 400-MW solar project near Vulcan, a town roughly one-hour by car southeast of Calgary.
“So now we’re getting close to 700 MW (of solar power),” Shaffer said, which is three times the AESO forecast.
