A giant solar wing ripped as it was being unfurled by astronauts aboard the International Space Station, creating another problem for NASA at the orbiting outpost.

The next shuttle flight could be delayed if this latest problem isn't resolved quickly, said NASA's space station program manager, Mike Suffredini. Atlantis is supposed to lift off in early December with a European laboratory.

"We don't clearly know what we're dealing with yet, and as soon as we know what we're dealing with, then we can talk about what our next steps are," Suffredini said.

The astronauts immediately halted the wing extension when they spotted the damage. By then, the solar panel was already extended almost 30 of its 35 metres. Space station commander Peggy Whitson said the sun angle prevented her and the others from seeing the 75-centimetre tear sooner.

"It's just the way it goes," Mission Control said consolingly.

The torn solar wing can still provide power. NASA's bigger concern is the structural problem posed by a partially deployed panel.

The damage was especially agonizing for the 10 space travellers because it came on the heels of an otherwise hugely successful day. Two of shuttle Discovery's crew had just wrapped up a seven-hour spacewalk and were still revelling in the smooth extension of the first of two retracted solar wings on a newly installed beam.

During the spacewalk – the third of their mission – Scott Parazynski and Douglas Wheelock installed a massive beam holding a pair of solar wings, which were folded up like an accordion. It took three days to move the beam from one location on the space station to another almost 45 metres away, and was considered one of the hardest construction jobs ever attempted in orbit.

Parazynski also dealt with the other problem on the space station, inspecting one of two rotary joints that keep the station's solar panels turned toward the sun.

Steel shavings were found during a spacewalk over the weekend in the joint on the right side of the station, and Parazynski was asked to look at the left joint for comparison. Everything inside that joint was shiny and looked pristine.

Until NASA figures out what's grinding inside the gears and fixes it, the right joint will remain in a parked position as much as possible, limiting power collection.

NASA plans to take a closer look at the malfunctioning joint during a spacewalk, although that work might be upstaged by the solar wing trouble.

At Mission Control's request, Whitson retracted the torn solar wing just a bit to ease tension on it. She said there appeared to be quite a lot of deformation to the entire area, with several sections bowed backward and kinked in various places.

The astronauts beamed down pictures of the damage so engineers could determine how bad it was and what, if anything, could be done about it.

Suffredini said the wing can provide 97 per cent power since the power line doesn't appear to be damaged. He said spacewalking astronauts could cut whatever might be snagging the solar wing, like a hinge, and possibly sew up the tear. For almost any repair, the wing probably would have to be retracted in order for the crew to reach the damage.

"We have a lot of options. We're in a good config (configuration) to sit here and work through this problem," he said.

Discovery's space station construction mission has already been extended a day because of the solar joint problem, with landing set for next November 7. Suffredini hinted that another two days could be added to the flight if the newest problem is deemed serious enough.

Electric shock: China power demand drops as coronavirus shutters plants

China Industrial Power Demand 2020 highlights COVID-19 disruption to electricity consumption as factory output stalls; IHS Markit estimates losses equal to Chile's usage, impacting thermal coal, LNG, and Hubei's industrial load.

 

Key Points

An analysis of COVID-19's hit to China's electricity use, cutting industry demand and fuel needs for coal and LNG.

✅ 73 billion kWh loss equals Chile's annual power use

✅ Cuts translate to 30m tonnes coal or 9m tonnes LNG

✅ Hubei peak load 21 percent below plan amid shutdowns

 

China’s industrial power demand in 2020 may decline by as much as 73 billion kilowatt hours (kWh), according to IHS Markit, as the outbreak of the coronavirus has curtailed factory output and prevented some workers from returning to their jobs.

The cut represents about 1.5% of industrial power consumption in China. But, as the country is the world’s biggest electricity consumer and analyses of China's electricity appetite routinely underscore its scale, the loss is equal to the power used in the whole of Chile and it illustrates the scope of the disruption caused by the outbreak.

The reduction is the energy equivalent of about 30 million tonnes of thermal coal, at a time when China aims to reduce coal power production, or about 9 million tonnes of liquefied natural gas (LNG), IHS said. The coal figure is more than China’s average monthly imports last year while the LNG figure is a little more than one month of imports, based on customs data.

China has tried to curtail the spread of the coronavirus that has killed more than 1,400 and infected over 60,000 by extending the Lunar New Year holiday for an extra week and encouraging people to work from home, measures that contributed to a global dip in electricity demand as well.

Last year, industrial users consumed 4.85 trillion kWh electricity, accounting for 67% of the country’s total, even as India's electricity demand showed sharp declines in the region.

Xizhou Zhou, the global head of power and Renewables at IHS Markit, said that in a severe case where the epidemic goes on past March, China’s economic growth will be only 4.2% during 2020, down from an initial forecast of 5.8%, while power consumption will climb by only 3.1%, down from 4.1% initially, even as power cuts and blackouts raise concerns.

“The main uncertainty is still how fast the virus will be brought under control,” said Zhou, adding that the impact on the power sector will be relatively modest from a full-year picture in 2020, even though China's electric power woes are already clouding solar markets.

In Hubei province, the epicenter of the virus outbreak, the peak power load at the end of January was 21% less than planned, mirroring how Japan's power demand was hit during the outbreak, data from Wood Mackenzie showed.

Industrial operating rates point to a firm reduction in power consumption in China.

Utilization rates at plastic processors are between 30% and 60% and the low levels are expected to last for another two week, according to ICIS China.

Weaving machines at textile plants are operating at below 10% of capacity, the lowest in five years, ICIS data showed. China is the world’s biggest textile and garment exporter.

Wind has become the ‘most-used’ source of renewable electricity generation in the US

U.S. Wind Generation surpassed hydroelectric output in 2019, EIA data shows, becoming the top renewable electricity source, driven by PTC incentives, expanded capacity, and utility-scale projects across states, boosting the national electricity mix.

 

Key Points

U.S. Wind Generation is the nation's top renewable, surpassing hydro as EIA-tracked capacity grows under PTC incentives.

✅ EIA: wind topped hydro in 2019, over 300M MWh generated

✅ PTC credits spurred growth in utility-scale wind projects

✅ 103 GW installed; 77% added in the last decade

 

Last year saw wind power surging in the U.S. to overtake hydroelectric generation for the first time, according to data from the U.S. Energy Information Administration (EIA).

Released Wednesday, the figures from the EIA’s “Electric Power Monthly” report show that yearly wind generation hit a little over 300 million megawatt hours (MWh) in 2019. This was roughly 26 million MWh more than hydroelectric production.

Wind now represents the “most-used renewable electricity generation source” in the U.S., the EIA said, and renewables hit a 28% monthly record in April in later data.

Overall, total renewable electricity generation — which includes sources such as solar's 4.7% share in 2022 as one example, geothermal and landfill gas — at utility scale facilities hit more than 720 million MWh in 2019, compared to just under 707 million MWh in 2018. To put things in perspective, generation from coal came to more than 966 million MWh in 2019, while renewables surpassed coal in 2022 nationally according to later analyses.

According to the EIA’s “Today in Energy” briefing, which was also published Wednesday, generation from wind power has grown “steadily” across the last decade, and by 2020, renewables became the second-most prevalent source in the U.S. power mix.

This, it added, was partly down to the extension of the Production Tax Credit, or PTC, amid favorable government plans supporting solar and wind growth. According to the EIA, the PTC is a system which gives operators a tax credit per kilowatt hour of renewable electricity production. It applies for the first 10 years of a facility’s operation.

At the end of 2019, the country was home to 103 gigawatts (GW) of wind capacity, with 77% of this being installed in the last decade, and wind capacity surpassed hydro in 2016 according to industry data. The U.S. is home 80 GW of hydroelectric capacity, according to the EIA.

“The past decade saw a steady increase in wind capacity across the country and we capped the decade with a monumental achievement for the industry in reaching more than 100 GW,” Tom Kiernan, the American Wind Energy Association’s CEO, said in a statement issued Thursday.

“And more wind energy is coming, as the industry is well into investing $62 billion in new projects over the next few years that put us on the path to achieving 20 percent of the nation’s electricity mix in 2030,” Kiernan went on to state.

“As a result, wind is positioned to remain the largest renewable energy generator in the country for the foreseeable future.”

N.L. premier says Muskrat Falls costs are too great for optimism about benefits

Muskrat Falls financial impact highlights a hydro megaproject's cost overruns, rate mitigation challenges, and inquiry findings in Newfoundland and Labrador, with power exports, Churchill River generation, and subsea cables shaping long-term viability.

 

Key Points

It refers to the project's burden on provincial finances, driven by cost overruns, rate hikes, and debt risks.

✅ Costs rose to $12.7B from $6.2B; inquiry cites suppressed risks.

✅ Rate mitigation needed to offset power bill shocks.

✅ Exports via subsea cables may improve long-term viability.

 

Newfoundland and Labrador's premier says the Muskrat Falls hydro megaproject is currently too much of a massive financial burden for him to be optimistic about its long-term potential.

"I am probably one of the most optimistic people in this room," Liberal Premier Dwight Ball told the inquiry into the project's runaway cost and scheduling issues, echoing challenges at Manitoba Hydro that have raised similar concerns.

"I believe the future is optimistic for Newfoundland Labrador, of course I do. But I'm not going to sit here today and say we have an optimistic future because of the Muskrat Falls project."

Ball, who was re-elected on May 16, has been critical of the project since he was opposition leader around the time it was sanctioned by the former Tory government.

He said Friday that despite his criticism of the Labrador dam, which has seen costs essentially double to more than $12.7 billion, he didn't set out to celebrate a failed project.

He said he still wants to see Muskrat Falls succeed someday through power sales outside the province, but there are immediate challenges -- including mitigating power-rate hikes once the dam starts providing full power and addressing winter reliability risks for households.

"We were told the project would be $6.2 billion, we're at $12.7 (billion). We were never told this project would be nearly 30 per cent of the net debt of this province just six, seven years later," the premier said.

"I wanted this to be successful, and in the long term I still want it to be successful. But we have to deal with the next 10 years."

The nearly complete dam will harness Labrador's lower Churchill River to provide electricity to the province as well as Nova Scotia and potentially beyond through subsea cables, while the legacy of Churchill Falls continues to shape regional power arrangements.

Ball's testimony wraps up a crucial phase of hearings in the extensive public inquiry.

The inquiry has heard from dozens of witnesses, with current and former politicians, bureaucrats, executives and consultants, amid debates over Quebec's electricity ambitions in the region, shedding long-demanded light on what went on behind closed doors that made the project go sideways.

Some witnesses have suggested that estimates were intentionally suppressed, and many high-ranking officials, including former premiers, have denied seeing key information about risk.

On Thursday, Ball testified to his shock when he began to understand the true financial state of the project after he was elected premier in 2015.

On Friday, Ball said he has more faith in future of the offshore oil and gas industry, and emerging options like small nuclear reactors, for example, than a mismanaged project that has put immense pressure on residents already struggling to make ends meet.

After his testimony, Ball said he takes some responsibility for a missed opportunity to mitigate methylmercury risks downstream from the dam through capping the reservoir, in parallel with debates over biomass power in electricity generation, something he had committed to doing before it is fully flooded this summer.

Still to come is a third phase of hearings on future best practices for issues like managing large-scale projects and independent electricity planning, two public feedback sessions and closing submissions from lawyers.

The final report from the inquiry is due before Dec. 31.

Charting a path to net zero electricity emissions by the middle of the century

Clean Energy Standard charts a federal path to decarbonize the power sector, scaling renewables, wind, solar, nuclear, and carbon capture to slash emissions, create green jobs, and reach net-zero targets amid the climate crisis.

 

Key Points

A federal policy to expand clean power and cut emissions with renewables, nuclear, and carbon capture toward net-zero.

✅ Mandates annual increases in clean electricity supply

✅ Includes renewables, nuclear, hydro, and carbon capture

✅ Targets rapid emissions cuts and net-zero by mid-century

 

The world has been put on notice. Last year, both the UN Intergovernmental Panel on Climate Change and the U.S. National Climate Assessment warned that we need to slash greenhouse gas emissions to avoid disastrous impacts of global warming. Their direct language forecasting devastating effects on our health, economics, environment, and ways of life has made even more urgent the responsibility we all have to act boldly to combat the climate crisis.

This week, we’re adding one important tool for addressing the climate crisis to the national conversation.

Together, we’re taking that bold action. The Climate reports made clear that to limit the global temperature rise and stave off devastating impacts to our climate—human-caused CO2 emissions must fall rapidly by 2030 and that we, as a global community, underscored at the Katowice climate talks, must reach net-zero emissions by the middle of the century. The Clean Energy Standard is federal legislation that offers a pathway toward decarbonizing our power sector and helping our nation accomplish a goal of net-zero emissions by the 2050s.

Under this plan, any company selling retail electricity will have a mandate to increase the amount of clean energy provided to its customers. It will incentivize clean electricity investment to put the U.S. on a sustainable path.

To deal most effectively with a crisis, all tools must be on the table. Our plan focuses solely on emissions, and there is a place for all technologies that can put us on the path to net zero. That will mean drastic increases in wind and solar energy for sure, as states like California pursue a 100% carbon-free electricity mandate to accelerate deployment, but nuclear power, hydro power, and fossil fuels with carbon capture and storage all have important roles to play.

We’re doing this because the science is clear – tackling our climate crisis requires serious and rapid action to control greenhouse gas emissions, and the push for decarbonization is irreversible according to many. Inaction on the climate crisis puts our families at risk, and we’re not wasting any time. This is also an opportunity to create good-paying green jobs that can last generations and uplift the middle class.

We are doing this for the environment, but also for jobs and economic competitiveness. The green economy is the future and we’re ready to see it grow, with states like New York advancing a Green New Deal that drives innovation. The United States can lead, or we can follow, and we want our nation to lead.

And, because as a New Mexican and a Minnesotan, we know that the impacts of climate change go far beyond the headlines and political discourse. It means devastation within tamarack forests and an increase in deadly fires. It means hotter summers and shorter winters with extreme temperature swings throughout the year. It means devastating flash floods with increasingly intense rain. It’s impacting our pocketbooks when farmers and small businesses who work the land in rural communities are unable to make ends meet.

States across the country are already acting to combat the climate crisis – including Minnesota's 2050 carbon-free electricity plan and New Mexico. But in order to truly address climate change, we have to be in this together as Americans. If the problem is far-reaching, our solutions must be equally as holistic.

It's why we've worked with green groups and activists, unions, and communities across the country - from urban to rural - to create a solution that understands the different starting points communities face in reaching net zero emissions, but doesn't shrink from the absolute need to reach that standard.

There is not one solution to climate change – it will take a collective group of individuals prepared to boldly act. And we are ready to take on that fight.

In Congress, we have formed the House Select Committee on the Climate Crisis and the Senate Democrats’ Special Committee on the Climate Crisis to hear from everyday Americans how climate change is affecting them – and how we can come together to find solutions that build on the historic climate deal passed this year. We have heard the stories of young people worried about their futures. And we realize there is a sense of urgency to act.

Over the coming weeks and months, we will be building support from communities across the country to make this plan a reality. We will continue working with stakeholders to ensure every voice is heard. Most importantly, we will continue listening to you and your communities.

Emissions rise 2% in Australia amid increased pollution from electricity and transport

Australia's greenhouse gas emissions rose in Q2 as electricity and transport pollution increased, despite renewable energy growth. Net zero targets, carbon dioxide equivalent metrics, and land use changes underscore mixed trends in decarbonisation.

 

Key Points

About 499-500 Mt CO2-e annually, with a 2% quarterly rise led by electricity and transport.

✅ Q2 emissions rose to 127 Mt from 124.4 Mt seasonally adjusted

✅ Electricity sector up to 41.6 Mt; transport added nearly 1 Mt

✅ Land use remains a net sink; renewables expanded capacity

 

Australia’s greenhouse gas emissions rose in the June quarter by about 2% as pollution from the electricity sector and transport increased.

Figures released on Tuesday by the Morrison government showed that on a year to year basis, emissions for the 12 months to last June totalled 498.9m tonnes of carbon dioxide equivalent. That tally was down 2.1%, or 10.8m tonnes compared with the same period a year earlier.

However, on a seasonally adjusted quarterly basis, emissions increased to 127m tonnes, or just over 2%, from the 124.4m tonnes reported in the March quarter. For the year to March, emissions totalled 494.2m tonnes, underscoring the pickup in pollution in the more recent quarter even as global coal power declines worldwide.

A stable pollution rate, if not a rising one, is also implied by the government’s release of preliminary figures for the September quarter. They point to 125m tonnes of emissions in trend terms for the July-September months, bringing the year to September total to about 500m tonnes, the latest report said.

The government has made much of Australia “meeting and beating” climate targets. However, the latest statistics show mostly emissions are not in decline despite its pledge ahead of the Glasgow climate summit that the country would hit net zero by 2050, and AEMO says supply can remain uninterrupted as coal phases out over the next three decades.

“Nothing’s happening except for the electricity sector,” said Hugh Saddler, an honorary associate professor at the Australian National University. Once Covid curbs on the economy eased, such as during the current quarter, emission sources such as from transport will show a rise, he predicted.

Falling costs for new wind and solar farms, with the IEA naming solar the cheapest in history worldwide, are pushing coal and gas out of electricity generation, as well as pushing down power prices. In seasonally adjusted terms, though, emissions for that sector rose from 39.7m tonnes the March quarter to 41.6m in the June one.

Most other sectors were steady, with pollution from transport adding almost 1m tonnes in the June quarter.

On an annual basis, a 500m tonnes tally is the lowest since records began in the 1990s, and IEA reported global emissions flatlined in 2019 for context. That lower trajectory, though, is lower due much to the land sector remaining a net sink even as some experts raise questions about the true trends when it comes to land clearing.

According to the government, this sector – known as land use, land-use change and forestry – amounted to a net reduction of emissions of 24.4m tonnes, or almost negative 5% of the national total, in the year to June.

“The magnitude of this net sink has decreased by 0.6% (0.2 Mt CO2-e) on the previous 12 months due to an increase in emissions from agricultural soils, partially offset by a continuing decline in land clearing emissions,” the latest report said.

For its part, the government also touted the increase of renewable energy, as seen in Canada's electricity progress too, as central to driving emissions lower.

“Since 2017, Australia’s consumption of renewable energy has grown at a compound annual rate of 4.6%, with more than $40bn invested in Australia’s renewable energy sector,” Angus Taylor, the federal energy minister said, while UK net zero policy changes show a different approach. “Last year, Australia deployed new solar and wind at eight times the global per capita average.”

ANU’s Saddler said the main driver had been the 2020 Renewable Energy Target that the Coalition government had cut, and had anyway been implemented “a very considerable time ago”.

Tim Baxter, the Climate Council’s senior researcher, said “the time for leaning on the achievements of others is long since past”.

“We need a federal government willing to step up on emissions reductions and take charge with real policy, not wishlists,” he said, referring to the government’s net zero plan to rely on technologies to cut pollution in pursuit of a sustainable electric planet in practice, some of which don’t exist now.
