The former Nanticoke Generating Station site, located on the northern shore of Lake Erie, has been transformed into a 44-megawatt clean energy facility that hosts 192,431 solar panels across 260 acres.
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.
6.5 million people are employed in the clean-energy sector.
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
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.
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
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.”

lobbying for the Keystone XL pipeline, for example.
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.
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.”

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.
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.”

“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.

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.”

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 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.”
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
“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.

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.
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.
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.”
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.
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.”
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.
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.
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

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
data from the US Department of Energy, PV Magazine calculates that 14%

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.
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.”
