Iran boosts nuclear processing program

Summerland Solar+Storage Project brings renewable energy to a municipal utility with photovoltaic panels and battery storage, generating 1,200 megawatts from 3,200 panels on Cartwright Mountain to boost grid resilience and local clean power.

Key Points

A municipal solar PV and battery system enabling Summerland Power to self-generate electricity on Cartwright Mountain.

✅ 3,200 panels, 20-year batteries, 35-year panel lifespan

✅ Estimated $7M cost, $6M in grants, utility reserve funding

✅ Site near grid lines; 2-year timeline with 18-month lead

A proposed solar energy project, to be constructed on municipally-owned property on Cartwright Mountain, will allow Summerland Power to produce some of its own electricity, similar to how Summerside's wind power supplies a large share locally.

On Monday evening, municipal staff described the Solar+Storage project, aligning with insights from renewable power developers that combining resources yields better projects.

The project will include around 3,200 solar panels and storage batteries, giving Summerland Power the ability to generate 1,200 megawatts of electrical power.

This is the amount of energy used by 100 homes over the course of a year.

The solar panels have an estimated life expectancy of 35 years, while the batteries have a life expectancy of 20 years.

“It’s a really big step for a small utility like ours,” said Tami Rothery, sustainability/alternative energy coordinator for Summerland. “We’re looking forward to moving towards a bright, sunny energy future.”

She said the price of solar panels has been dropping, with lower-cost solar contracts reported in Alberta, and the quality and efficiency of the panels has increased in recent years.

The total cost of the project is around $7 million, with $6 million to come from grant funding and the remainder to come from the municipality’s electrical utility reserve fund, while policy changes such as Nova Scotia's solar charge delay illustrate evolving market conditions.

The site, a former public works yard and storage area, was selected from 108 parcels of land considered by the municipality.

She said the site, vacant since the 1970s, is close to main electrical lines and will not be highly visible once the panels are in place, much like unobtrusive rooftop solar arrays in urban settings.

Access to the site is restricted, resulting in natural security to the solar installation.

Jeremy Storvold, general manager of Summerland’s electrical utility, said the site is 2.5 kilometres from the Prairie Valley electrical substation and close to the existing public works yard.

However, some in the audience on Monday questioned the location of the proposed solar installation, suggesting the site would be better suited for affordable housing in the community.

The timeline for the project calls for roughly two years before the work will be completed, since there is an 18-month lead time in order to receive good quality solar panels, reflecting the surge in Alberta's solar growth that is straining supply chains.

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.

Alberta Coal Phase-Out signals a clean energy transition, replacing coal with natural gas and renewables, cutting greenhouse gas emissions, leveraging a carbon levy, and supporting workers in Alberta's evolving electricity market.

Key Points

Alberta Coal Phase-Out moves power from coal to lower-emission natural gas and renewables to reduce grid emissions.

✅ Last coal plant closed: Genesee Generating Station, Sept 30, 2023

✅ Shift to natural gas and renewables lowers emissions

✅ Carbon levy and incentives accelerated clean power build-out

The closure of the Genesee Generating Station on September 30, 2023, marked a significant milestone in Alberta's energy history, as the province moved to retire coal power by 2023 ahead of its 2030 provincial deadline. The Genesee, located near Calgary, was the province's last remaining coal-fired power plant. Its closure represents the culmination of a multi-year effort to transition Alberta's electricity sector away from coal and towards cleaner sources of energy.

For decades, coal was the backbone of Alberta's electricity grid. Coal-fired plants were reliable and relatively inexpensive to operate. However, coal also has a significant environmental impact. The burning of coal releases greenhouse gases, including carbon dioxide, a major contributor to climate change. Coal plants also produce air pollutants such as sulfur dioxide and nitrogen oxide, which can cause respiratory problems and acid rain, and in some regions electricity is projected to get dirtier as gas use expands.

In recognition of these environmental concerns, the Alberta government began to develop plans to phase out coal-fired power generation in the early 2000s. The government implemented a number of policies to encourage the shift from coal to cleaner energy such as natural gas and renewable energy. These policies included providing financial incentives for the construction of new natural gas plants and renewable energy facilities, as well as imposing a carbon levy on coal-fired generation.

The phase-out of coal was also driven by economic factors. The cost of natural gas has declined significantly in recent years, making it a more competitive fuel source for electricity generation as producers switch to gas under evolving market conditions. Additionally, the Alberta government faced increasing pressure from the federal government to reduce greenhouse gas emissions.

The transition away from coal has not been without its challenges. Coal mining and coal-fired power generation have long been important parts of Alberta's economy. The closure of coal plants has resulted in job losses in the affected communities. The government has implemented programs to help workers transition to new jobs in the clean energy sector.

Despite these challenges, the closure of the Genesee Generating Station is a positive development for Alberta's environment and climate. Coal-fired power generation is one of the largest sources of greenhouse gas emissions in Alberta, and recent wind generation outpacing coal underscores the sector's transformation. The closure of the Genesee is expected to result in a significant reduction in emissions, helping Alberta to meet its climate change targets.

The transition away from coal also presents opportunities for Alberta. The province has vast natural gas resources, which can be used to generate electricity with lower emissions than coal. Alberta is also well-positioned to develop renewable energy sources, such as wind power and solar power. These renewable energy sources can help to further reduce emissions and create new jobs in the clean energy sector.

The closure of the Genesee Generating Station is a significant milestone in Alberta's energy history. It represents the end of an era for coal-fired power generation in the province, a shift mirrored by the UK's last coal station going offline earlier this year. However, it also marks the beginning of a new era for Alberta's energy sector. By transitioning to cleaner sources of energy, Alberta can reduce its environmental impact and create a more sustainable energy future.

Rising Greenhouse Gas Concentrations drive climate change, with CO2, methane, and nitrous oxide surging; WMO data show higher radiative forcing, elevated pre-industrial baselines, and persistent atmospheric concentrations despite Paris Agreement emissions pledges.

Key Points

Increasing atmospheric CO2, methane, and nitrous oxide levels that raise radiative forcing and drive warming.

✅ WMO data show CO2 at 407.8 ppm in 2018, above decade average

✅ Methane and nitrous oxide surged, elevating total radiative forcing

✅ Concentrations differ from emissions; sinks absorb about half

The World Meteorological Organization (WMO) says the increase in CO2 was just above the average rise recorded over the last decade.

Levels of other warming gases, such as methane and nitrous oxide, have also surged by above average amounts.

Since 1990 there's been an increase of 43% in the warming effect on the climate of long lived greenhouse gases.

The WMO report looks at concentrations of warming gases in the atmosphere rather than just emissions.

The difference between the two is that emissions refer to the amount of gases that go up into the atmosphere from the use of fossil fuels, such as burning coal for coal-fired electricity generation and from deforestation.

Concentrations are what's left in the air after a complex series of interactions between the atmosphere, the oceans, the forests and the land. About a quarter of all carbon emissions are absorbed by the seas, and a similar amount by land and trees, while technologies like carbon capture are being explored to remove CO2.

Using data from monitoring stations in the Arctic and all over the world, researchers say that in 2018 concentrations of CO2 reached 407.8 parts per million (ppm), up from 405.5ppm a year previously.

This increase was above the average for the last 10 years and is 147% of the "pre-industrial" level in 1750.

The WMO also records concentrations of other warming gases, including methane and nitrous oxide, and some countries have reported declines in certain potent gases, as noted in US greenhouse gas controls reports, though global levels remain elevated. About 40% of the methane emitted into the air comes from natural sources, such as wetlands, with 60% from human activities, including cattle farming, rice cultivation and landfill dumps.

Methane is now at 259% of the pre-industrial level and the increase seen over the past year was higher than both the previous annual rate and the average over the past 10 years.

Nitrous oxide is emitted from natural and human sources, including from the oceans and from fertiliser-use in farming. According to the WMO, it is now at 123% of the levels that existed in 1750.

Last year's increase in concentrations of the gas, which can also harm the ozone layer, was bigger than the previous 12 months and higher than the average of the past decade.

What concerns scientists is the overall warming impact of all these increasing concentrations. Known as total radiative forcing, this effect has increased by 43% since 1990, and is not showing any indication of stopping.

There is no sign of a slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris agreement on climate change and the ongoing global energy transition efforts," said WMO Secretary-General Petteri Taalas.

"We need to translate the commitments into action and increase the level of ambition for the sake of the future welfare of mankind," he added.

"It is worth recalling that the last time the Earth experienced a comparable concentration of CO2 was three to five million years ago. Back then, the temperature was 2-3C warmer, sea level was 10-20m higher than now," said Mr Taalas.

The UN Environment Programme will report shortly on the gap between what actions countries are taking to cut carbon, for example where Australia's emissions rose 2% recently, and what needs to be done to keep under the temperature targets agreed in the Paris climate pact.

Preliminary findings from this study, published during the UN Secretary General's special climate summit last September, indicated that emissions continued to rise during 2018, although global emissions flatlined in 2019 according to the IEA.

Both reports will help inform delegates from almost 200 countries who will meet in Madrid next week for COP25, following COP24 in Katowice the previous year, the annual round of international climate talks.

Champlain Hudson Power Express Converter Station brings Canadian hydropower via HVDC to Queens, converting 1,250 MW to AC for New York City's grid, replacing a retired fossil site with a zero-emission, grid-scale clean energy hub.

Key Points

A Queens converter turning 1,250 MW HVDC hydropower into AC for NYC's grid, repurposing an Astoria fossil site.

✅ 340-mile underwater/underground HVDC link from Quebec to Queens

✅ 1,250 MW DC-AC conversion feeding directly into NY grid by 2026

✅ Replaces Astoria oil site; supports NY's 70% renewables by 2030

New York Governor Kathy Hochul has announced the start of construction on the converter station of the Champlain Hudson Power Express transmission line, a project to bring electricity generated from Canadian hydropower to New York City.

The 340 mile (547 km) transmission line is a proposed underwater and underground high-voltage direct current power transmission line to deliver the power from Quebec, Canada, to Queens, New York City. The project is being developed by Montreal-based public utility Hydro-Quebec (QBEC.UL) and its U.S. partner Transmission Developers, while neighboring New Brunswick has signed NB Power deals to bring more Quebec electricity into the province.

The converter station for the line will be the first-ever transformation of a fossil fuel site into a grid-scale zero-emission facility in New York City, its backers say.

Workers have already removed six tanks that previously stored 12 million gallons (45.4 million liters) of heavy oil for burning in power plants and nearly four miles (6.44 km) of piping from the site in the Astoria, Queens neighborhood, echoing Hydro-Quebec's push to wean the province off fossil fuels as regional power systems decarbonize.

The facility is expected to begin operating in 2026, even as the Ontario-Quebec power deal was not renewed elsewhere in the region. Once the construction is completed, it will convert 1,250 megawatts of energy from direct current to alternating current power that will be fed directly into the state's power grid, helping address transmission constraints that have impeded incremental Quebec-to-U.S. power deliveries.

“Renewable energy plays a critical role in the transformation of our power grid while creating a cleaner environment for our future generations,” Hochul said. The converter station is a step towards New York’s target for 70% of the state’s electricity to come from renewable sources by 2030, as neighboring Quebec has closed the door on nuclear power and continues to lean on hydropower.

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

Key Points

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

✅ Uses single-cycle light pulses to drive electron tunneling

✅ Achieves 600 attosecond current switching in nano-gaps

✅ Enables optoelectronic, plasmonic devices beyond silicon

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

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

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

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

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

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

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

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

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

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

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

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

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