The project has just been completed by PCL Construction, a company that was commissioned to design, engineer and build it, as well as supply the photovoltaic solar panels and racking system. Behind the idea and funding are Ontario Power Generation, the Six Nations of the Grand River Development Corporation and the Mississaugas of the Credit First Nation.

The opening of the solar facility coincides with the one-year anniversary of the demolition of the Nanticoke 650-feet smokestacks. It has also been almost five years since the station burned its last piece of coal.

In its heyday, the Nanticoke Generating Station was the largest coal-fired plant in North America, providing 15% of Ontario’s electricity. After serving the province for more than 40 years, it stopped using coal as fuel in 2013. Two years later, the site was safely closed while the switchyards, operated by Hydro One Networks, remain in operation as a significant hub for the electricity grid in the southwestern part of the region.

Official information indicates that some parts of the former facility, such as the powerhouse, still need to be torn down. Following the last demolition scheduled for September 2019, the site will undergo a restoration process in 2020.

Since 2014, Ontario Power Generation stopped using coal to generate electricity in Canada’s most populous province, a move that resulted in the equivalent of taking 7 million cars off the road.

Canada’s green energy sector has grown so quickly and has become such an important part of the economy that it now employs more people than the oil sands.

About $25-billion has been invested in Canada’s clean-energy sector in the past five years, and employment is up 37 percent, according to a new report from climate think tank Clean Energy Canada to be released Tuesday. That means the 23,700 people who work in green energy organizations outnumber the 22,340 whose work relates to the oil sands, the report says.

Worldwide, 6.5 million people are employed in the clean-energy sector.

“Clean energy has moved from being a small niche or boutique industry to really big business in Canada,” said Merran Smith, director of Clean Energy Canada. The investment it has gleaned since 2009 is roughly the same as has been pumped into agriculture, fishing and forestry combined, she said. The industry will continue to show huge growth potential, beyond most other business sectors, she added.

While investment has boomed, the energy-generating capacity of wind, solar, run-of-river hydro and biomass plants has expanded by 93 percent since 2009, the report says.

Clean Energy Canada says the industry’s growth has been accelerated by supportive policies in a handful of provinces. However, despite its increased importance to the national economy, clean energy is still not a priority in Ottawa, it says.

Government backing is crucial for this industry, Ms. Smith said, as it has been for our other strategic industries. “Every major industrial sector in Canada – from the aerospace industry to the oil sands – has gotten off the ground with support from the federal government. But in the clean-energy sector, the federal government is really missing in action.”

Not only does the oil industry still get more substantial subsidies, she said, it also eats up a good deal of the country’s diplomatic relations efforts – through the lobbying for the Keystone XL pipeline, for example.

The report acknowledges that Ottawa has set some groundwork for clean energy, by supporting clean-energy demonstration and research projects, cutting energy waste and discouraging the construction of conventional coal-power plants. But it says the federal government needs to do a lot more. Ottawa should create tax supports for renewable technologies, pump infrastructure money into new electrical transmission lines and clean-energy projects, and put a price on carbon, it says.

As for the provinces, Alberta and Saskatchewan in particular should follow Ontario, Quebec and British Columbia in getting into the renewable-energy game, Ms. Smith said. Still, the necessity for this shift is beginning to gain some traction, she said, noting that Alberta Finance Minister Robin Campbell said last week that the province has to “get off the oil train.”

That’s a view shared by Kent Brown, chief executive officer of BluEarth Renewables Inc., a company that focuses on clean energy from the heart of the oil patch in Calgary. This new sector is now “a huge piece of the economy,” Mr. Brown said. “It creates a lot of meaningful jobs.”

BluEarth, which runs a portfolio of hydro, solar and wind projects in British Columbia, Alberta, Ontario and Nova Scotia, has created 35 new jobs in the past four years. That’s a small contribution but one that is being duplicated by hundreds of other firms across the clean-tech sector.

Clean-power generation is also not a slave to commodity prices and the subsequent boom and bust cycle that regularly hits the oil and gas sector, said Mr. Brown, who initially worked in the oil patch but developed a “deep dissatisfaction” with the lack of sustainability of the petroleum sector. While Alberta will remain a key oil player, it can also be a “true leader” renewables, he said.

The Clean Energy Canada report notes that much of the investment for Canada’s clean-tech expansion currently comes outside the country. Of the five largest investors since 2009, just one, Manulife Financial Corp., is Canadian. Two Japanese companies are in that top-five list, along with two German banking groups.

“The fact that foreign investors are coming to Canada to invest in our clean energy, tells us that we have a fantastic resource,” Ms. Smith said. “We need Bay Street to wake up and recognize this is where the puck is going.”

3,800 modules will be installed on top of Genesis place

Above the streets and atop Genesis Place lay hundreds of solar panels collecting sun to help power the recreation centre during the day and not just prevent emissions, but help pay for its own construction.

The City of Airdrie will soon be the proud owner of Canada’s largest municipal rooftop solar system.

Airdrie is a city in Alberta, Canada within the Calgary Region. It is located north of Calgary within the Calgary–Edmonton Corridor at the intersection of Queen Elizabeth II Highway and Highway 567.

Chris Reason, project manager for Capital Projects at the City of Airdrie, describes just how many solar panels will be gathering sunlight energy for Genesis Place.

“3,800 modules will be installed on top of Genesis place. It’s a phenomenal amount of panels if you’re new to the solar world. We’ve gone up to Leduc and we’ve looked at their solar panel system and we fell in love with it and we absolutely had to have our own.”

Global energy-related carbon emissions rose to a record high last year as energy demand and coal use increased, mainly in Asia, the International Energy Agency (IEA) says

Coal power plant
Coal-fired generation puts out about twice the amount of carbon dioxide – around 2,000 pounds for every megawatt-hour generated. Most of the emissions of human-caused (anthropogenic) greenhouse gases (GHG) come primarily from burning fossil fuels—coal, hydrocarbon gas liquids, natural gas, and petroleum—for energy use.

Several publications including the Washington Post, report “grim findings” from the International Energy Agency (IEA)’s latest annual report on global carbon emissions.

The report finds that not only are planet-warming CO2 emissions still increasing, but the world’s growing thirst for energy has led to higher emissions from coal-fired power plants than ever before.

The report adds that energy demand around the world grew by 2.3 percent over the past year (2018), marking the most rapid increase in a decade.

“We have seen an extraordinary increase in global energy demand in 2018, growing at its fastest pace this decade,” says Fatih Birol, the IEA’s executive director.

To meet that demand, largely fuelled by a booming economy, countries turned to an array of sources, including renewables. But nothing filled the void quite like fossil fuels, which satisfied nearly 70 percent of the skyrocketing electricity demand, according to the agency, which analyzes energy trends on behalf of 30 member countries, including the U.S.

Asia is now responsible for the majority of coal-fired power generation globally, and the average age of power plants there is now just 12 years, meaning they have decades to go before reaching their planned end of production in about 30 to 50 years.

Last year can also be considered another golden year for gas. But despite major growth in renewables, global emissions are still rising, demonstrating once again that more urgent action is needed on all fronts.”

Growth in emissions last year — 560m tonnes — is equivalent to the entire annual emissions from the aviation sector.

It was the second consecutive year of rising emissions, after a period during which CO2 emissions were mostly flat between 2014 and 2016.

“It seems like a vicious cycle,” said Mr. Birol, pointing out that in India air conditioning had become a big factor in power demand. “Heating and cooling are one of the biggest drivers of energy demand growth.”

Meanwhile, a new analysis shows that around three-quarters of U.S. coal production is now more expensive than solar and wind energy in providing electricity to American households.

“Even without major policy shift we will continue to see coal retire pretty rapidly,” said Mike O’Boyle, the co-author of the report for Energy Innovation, a renewables analysis firm. “Our analysis shows that we can move a lot faster to replace coal with wind and solar. The fact that so much coal could be retired right now shows we are off the pace.”

The study’s authors used public financial filings and data from the Energy Information Agency to work out the cost of energy from coal plants compared with wind and solar options within a 35-mile radius.

They found that 211 gigawatts of current U.S. coal capacity, 74 percent of the coal fleet, is providing electricity that’s more expensive than wind or solar.

By 2025 the picture becomes even clearer, with nearly the entire US coal system out-competed on cost by wind and solar, even when factoring in the construction of new wind turbines and solar panels.

Oxford PV perovksite-silicon tandem cell

Oxford PVTM – The Perovskite CompanyTM, the leader in the field of perovskite solar cells, announced a new, certified, world record for its perovskite-based solar cell.

Oxford PV’s 1 cm2 perovskite-silicon tandem solar cell has achieved a 28% conversion efficiency, certified by the National Renewable Energy Laboratory. The achievement edges out Oxford PV’s own previous certified record of 27.3% efficiency for its perovskite-silicon solar cell, announced earlier this year. 

Dr. Chris Case, Chief Technology Officer at Oxford PV commented, “Today’s record demonstrates the unprecedented pace of our technology development. We are continuing to push our perovskite-silicon solar cell technology, with a roadmap that extends beyond 30% efficiency. The solar cells we are developing are not only efficient but also stable. Similar devices from our research and development facility have passed at least 2000 hours of damp heat reliability testing, in line with IEC 61215 protocol.”

Frank P. Averdung, Chief Executive Officer at Oxford PV added, “2018 has been a significant year for Oxford PV. Alongside the pace of our technology advancements in both efficiency and stability, our pilot line is routinely producing commercial sized tandem solar cells for validation by our development partner – a major manufacturer of silicon solar cells and modules.  With new collaborations with key industry players strengthening our manufacturing capabilities, the foundations are in place, to move perovskite photovoltaics into commercial phase.”

Climate Change

A new study has revealed that the language used by the global climate change watchdog, the Intergovernmental Panel on Climate Change (IPCC), is overly conservative – and therefore the threats are much greater than the Panel’s reports suggest.

Published in the journal BioScience, the team of scientists from the University of Adelaide, Flinders University, the University of Bristol (UK), and the Spanish National Research Council has analysed the language used in the IPCC’s Fifth Assessment Report (from 2014).

“We found that the main message from the reports—that our society is in climate emergency—is lost by overstatement of uncertainty and gets confused among the gigabytes of information,” says lead author Dr. Salvador Herrando-Pérez, from the University of Adelaide’s Environment Institute and Australian Centre for Ancient DNA.

“The IPCC supports the overwhelming scientific consensus about human impact on climate change, so we would expect the reports’ vocabulary to be dominated by greater certainty on the state of climate science—but this is not the case.”

The IPCC assigns a level of certainty to climate findings using five categories of confidence and ten categories of probability. The team found the categories of intermediate certainty predominated, with those of highest certainty barely reaching 8% of the climate findings evaluated.

“The accumulation of uncertainty across all elements of the climate-change complexity means that the IPCC tends to be conservative,” says co-author Professor Corey Bradshaw, Matthew Flinders Fellow in Global Ecology at Flinders University. “The certainty is in reality much higher than even the IPCC implies, and the threats are much worse.”

“Uncertainty is to science what the score is to music—but it’s a two-edged sword: what the IPCC and the majority of the scientific community regard as a paradigm of rigour and transparency is exactly what the ‘merchants of doubt’ put forward as a weakness,” says Dr. Herrando-Pérez.

“However, climatic uncertainties are nothing but an expression of the climate risks we face, and should inspire action rather than indifference.”

The team says the IPCC reports should incorporate a clear connection between the certainty of thousands of scientific findings and the certainty that humans are vastly altering the Earth’s climate. The team recommends a new IPCC working group of communication specialists to oversee the language and effective dissemination, and convey the message accurately.

“Our evolutionary history tells us Earth will ultimately survive more aridity, more hurricanes, more floods, more sea-level rise, more extinctions and degraded ecosystems, but our society as we know it today might not unless we clearly articulate the magnitude of the threat it poses,” says Dr. Herrando-Pérez.

Key Points

  • The novel wind and solar energy-harvesting flags have been developed using flexible piezoelectric strips and flexible photovoltaic cells.
  • The aim of the study is to allow cheap and sustainable energy harvesting solutions which can be deployed and left to generate energy with little or no need for maintenance.
  • The research has been published in the journal Applied Energy.

Piezoelectric strips allow the flag to generate power through movement, whilst the photovoltaics is the best known method of harnessing electric power by using solar cells.

The study, conducted by researchers at The University of Manchester, is the most advanced of its kind to date and the first to simultaneously harvest wind and solar energies using inverted flags. The research has been published in the journal Applied Energy.

The newly developed energy harvesting flags are capable of powering remote sensors and small-scale portable electronics which can be used for environmental sensing such as to monitor pollution, sound levels and heat for example.

The aim of the study is to allow cheap and sustainable energy harvesting solutions which can be deployed and left to generate energy with little or no need for maintenance. The strategy is known as “deploy-and-forget” and this is the anticipated for model that so called smart cities will adopt when using remote sensors.

Jorge Silva-Leon, from Manchester’s School of Mechanical, Aerospace & Civil Engineering and lead-author of the study, says: “Under the action of the wind, the flags we built bend from side to side in a repetitive fashion, also known as Limit-Cycle Oscillations. This makes them perfectly suited for uniform power generation from the deformation of piezoelectric materials. Simultaneously, the solar panels bring a double benefit: they act as a destabilizing mass which triggers the onset of flapping motions at lower wind speeds, and of course are able to generate electricity from the ambient light.

Dr Andrea Cioncolini, co-author of the study, added: “Wind and solar energies typically have intermittencies that tend to compensate each other. The sun does not usually shine during stormy conditions, whereas calm days with little wind are usually associated with shiny sun. This makes wind and solar energies particularly well suited for simultaneous harvesting, with a view at compensating their intermittency.”

The team used and developed unique research techniques such as fast video-imaging and object tracking with advanced data-analysis to prove their flags worked. The developed harvesters were tested in wind speeds varying from 0 m/s (calm) to about 26 m/s (storm/whole gale) and 1.8 kLux constant light exposure, simulating a wide range of environmental conditions. Under these operation conditions, total power outputs of up to 3-4 milli-Watts were generated.

Dr Mostafa Nabawy, co-author of the study, says: “Our piezo/solar inverted flags were capable of generating sufficient power for a range of low power sensors and electronics that operate in the micro-Watt to milli-Watt power range within a number of potential practical applications in avionics, land and sea remote locations, and smart cities. We hope to develop the concept further in order to support more power-demanding applications such as an eco-energy generating charging-station for mobile devices.”

Dr Alistair Revell, co-author of work, highlights current and future research directions saying: “We are currently making use of a novel computational framework for modelling and simulation developed at The University of Manchester, building on a long tradition of Computational Fluid Dynamics in the group. The use of computers to model fluid-structure interactions is increasingly referred to as virtual engineering, and plays a key part in device development by reducing the number of models which need to be physically manufactured and tested.”

On Saturday, March 16, California set a new solar energy record. Just before 3 o’clock in the afternoon, solar output peaked at 10,765 megawatts, the highest amount ever, though just a smidgen more than the previous record set last June. According to the California Independent System Operator (CAISO), demand at that time, not including behind-the-meter solar, was around 18 gigawatts. Los Angeles and Sacramento are not part of the CAISO grid.

That meant solar was meeting 59% of the grid’s power needs at that moment.That’s wonderful news, but what should get solar proponents really excited is that CAISO was a net exporter of electricity to other systems at the time the record was set. As PV Magazine points out, CAISO is required by its existing contracts with out-of-state energy suppliers to import a certain amount of electricity even when it doesn’t need it.

When that happens, some of the locally generated electricity has to be exported, and in extreme cases, the generation is just shut off or dumped, a process known as curtailment in the industry. Since it is more difficult to decrease output on a moment-to-moment basis from traditional energy sources like hydro or gas-fired generating stations, the electricity curtailed most often comes from renewable energy facilities, especially solar.

Depending on market considerations at the time, sometimes CAISO actually has to pay other utility operators to take its excess electricity, particularly during the mid-afternoon when solar output is at its peak. But that didn’t happen in this instance. Growing battery storage capability in California is one of the reasons why.

The data from CAISO only tells part of the solar record story, however, since behind-the-meter solar — which is estimated to be half as much as grid-scale solar — is not included in those numbers. That means at that time on Saturday, March 16, total available solar energy within the CAISO system was closer to 16 gigawatts.

Based on data from the US Department of Energy, PV Magazine calculates that 14% of California’s annual demand for electricity was met from in-state solar resources last year and that number is expected to be far greater this year as California once again adds more solar generating capacity than any other state.

Opponents of solar and other renewables like to point out the cost of electricity in California has gone up steadily in the past decade, which they attribute entirely to the expense of building wind and solar generating facilities. What they ignore completely is the money utility customers have been forced to expend to keep unprofitable conventional generating facilities running and the burden that existing contracts impose on everyone.

They also totally exclude any intangible but very real health and environmental impacts from drilling for, transporting, and burning fossil fuels to make electricity. In today’s superheated political sphere, half-truths and outright lies are considered business as usual. Despite their distortions, renewable energy is rapidly displacing conventional generating plants, something that means we can all breathe a little bit easier.

Members of the European Parliament voted last week on a non-binding resolution endorsing a net-zero greenhouse gas emissions target for 2050 and increasing the European Union’s 2030 target.

European Parliament

Amidst a wide-ranging text adopted by 369 votes to 116 (and 40 abstentions), Members of the European Parliament (MEPs) expressed their support for only two of eight strategic pathways “for the economic, technological and social transformation needed for the Union to comply with the long-term temperature goal of the Paris Agreement” — the only two pathways which, according to the MEPs, “would enable the Union to reach net-zero GHG emissions by 2050 at the latest.”

The text adopted states that achieving net-zero greenhouse gas emissions by 2050 “requires swift action and considerable efforts at local, regional, national, and EU level, also involving all non-public actors.”

If the European Union is to achieve this target of “net-zero GHG emissions by 2050 at the latest” then, according to the adopted text, the 2030 ambition level must be raised “and aligned with net-zero 2050 scenarios.” Specifically, MEPs supports an update to the European Union’s Nationally Determined Contribution (NDC) — the mechanism embodying “efforts by each country to reduce national emissions and adapt to the impacts of climate change” (according to the United Nations Framework Convention on Climate Change) — to an economy-wide target of 55% domestic greenhouse gas emissions reductions by 2030 (compared with 1990 levels).

“With people turning out in record numbers for the climate, MEPs have shown they take citizens’ concerns seriously, and want to step up climate action,” said Imke Lübbeke, Head of Climate and Energy at WWF European Policy Office. “Their support for net zero greenhouse gas emissions in the EU by 2050 latest, and higher cuts by 2030, is an encouraging sign to EU Member States, who are currently considering the EU’s long-term climate plans and preparing their national climate and energy plans.”

The MEPs also welcomed demonstrations and student strikes across the EU, welcoming “the calls from these activists for greater ambition and swift action in order not to overshoot the 1.5°C climate limit.”
