Saudis look to nuclear for local power demand

Saudi Arabia Wind Power Market set to lead the Middle East, driven by Vision 2030 renewables goals, REPDO tenders, and PIF backing, adding 6.2GW wind capacity by 2028 alongside solar PV diversification.

Key Points

It is the emerging national segment leading Middle East wind growth, targeting 6.2GW by 2028 under Vision 2030 policies.

✅ Adds 6.2GW, 46% of regional wind capacity by 2028

✅ REPDO tenders and PIF funding underpin pipeline

✅ Targets: 16GW wind, 40GW solar under Vision 2030

Saudi Arabia will become a regional heavyweight in the Middle East's wind power market adding over 6GW in the next 10 years, according to new research by Wood Mackenzie Power & Renewables.

The report – 'Middle East Wind Power Market Outlook, 2019-2028’ – said developers will build 6.2GW of wind capacity in the country or 46% of the region’s total wind capacity additions between 2019 and 2028.

Wood Mackenzie Power & Renewables senior analyst Sohaib Malik said: “The integration of renewables in Vision 2030’s objectives underlines strong political commitment within Saudi Arabia.

“The level of Saudi ambition for wind and solar PV varies significantly, despite the cost parity between both technologies during the first round of tenders in 2018.”

Saudi Arabia has set a 16GW target for wind by 2030 and 40GW for solar, plans to solicit 60 GW of clean energy over the next decade, Wood Mackenzie added.

“Moving forward, the Renewable Energy Project Development Office will award 850MW of wind capacity in 2019, which is expected to be commissioned in 2021-2022, and increase the local content requirement in future tendering rounds,” Malik said.

However, Saudi Arabia will fall short of its current 2030 renewables target, despite growth projections and regional leadership, the report said.

Some 70% of the renewables capacity target is to be supported by the Public Investment Fund (PIF), the Saudi sovereign wealth fund, while the remaining capacity is to be awarded through REPDO.

“A central concern is the PIF’s lack of track record in the renewables sector and its limited in-house sectoral expertise,” said Malik

“REPDO, on the other hand, completed two renewables request for proposals after pre-developing the sites,” he said.

PIF is estimated to have $230bn of assets – targeted to reach $2 trillion under Vision 2030 – driven by investments in a variety of sectors ranging from electric vehicles to public infrastructure, Wood Mackenzie said.

“There is little doubt about the fund’s financial muscle, however, its past investment strategy focused on established firms in traditional industries,” Malik added.

“Aspirations to develop a value chain for wind and PV technologies locally is a different ball game and requires the PIF to acquire new capabilities for effective oversight of these ventures,” he said.

The report noted that regional volatility is expected to remain, with strong positive growth, driven by Jordan and Iran in 2018 expected to reverse in 2019, and policy shifts, as in Canada’s scaled-back projections, can influence outcomes.

Post-2020 Wood Mackenzie Power & Renewables sees regional demand returning to steady growth as global renewables set more records elsewhere.

“In 2018, developers added 185MW and 63MW of wind capacity in Jordan and Iran, respectively, compared to 53MW of capacity across the entire region in 2017, following a record year for renewables in 2016,” said Malik.

“The completion of the 89MW Al Fujeij and the 86MW Al Rajef projects in 2018 indicates that Jordan has 375MW of the region’s operational 675MW wind capacity.

“Iran followed with 278MW of installed capacity at the end of 2018. A slowdown in 2019 is expected, as project development activity softens in Iran.

“Additionally, delays in awarding the 400MW Dumat Al Jandal project in Saudi Arabia will limit annual capacity additions to 184MW.”

He added that a maturing project pipeline in the region supports the 2020-2021 outlook, even as wind power grew despite Covid-19 globally.

“Saudi Arabian demand serves as the foundation for regional demand. Regional demand diversification is also occurring, with Lebanon set to add 200-400MW to its existing permitted capacity pipeline of 202MW in 2019,” he said

“These developments pave the way for the addition of 2GW of wind capacity between 2019 and 2021.”

Wood Mackenzie Power & Renewables added that the outlook for solar in the region is “much more positive” than wind.

“Compared to only 6GW of wind power capacity, developers will add 53GW of PV capacity through 2024,” said Malik.

He added: “Solar PV, supported by trends such as China’s rapid PV growth in 2016, has become a natural choice for many countries in the region, which is endowed with world class solar energy resources.

“The increased focus on solar energy is demonstrated by ambitious PV targets across the region.”

Canada Oil Recession Outlook analyzes the Russia-Saudi price war, OPEC discord, COVID-19 demand shock, WTI and WCS collapse, Alberta oilsands exposure, U.S. shale stress, and GDP risks from blockades and fiscal responses.

Key Points

An outlook on how the oil price war and COVID-19 demand shock could tip Canada into recession and strain producers.

✅ WTI and WCS prices plunge on OPEC-Russia discord

✅ Alberta oilsands face break-even pressure near 30 USD WTI

✅ RBC flags global recession; GDP hit from blockades, virus

A war between Russia and Saudi Arabia for market share for oil may have been triggered by the COVID-19 pandemic in China, but the oil price crash contagion that it will spread could have impacts that last longer than the virus.

The prospects for Canada are not good.

Plunging oil prices, reduced economic activity from virus containment, and the fallout from weeks of railway blockades over the Coastal GasLink pipeline all add up to “a one-two-three punch that I think is almost inevitably going to put Canada in a position where its growth has to be negative,” said Dan McTeague, a former Liberal MP and current president of Canadians for Affordable Energy. The situation “certainly has the makings” of a recession, said Ken Peacock, chief economist for the Business Council of British Columbia.

“At a minimum, it’s going to be very disruptive and we’re going to have maybe one negative quarter,” Peacock said. “Whether there’s a second one, where it gets labeled a recession, is a different question. But it’s going to generate some turmoil and challenges over the next two quarters – there’s no doubt about that.”

RBC Economics on March 13 announced it now predicts a global recession and cut its growth projections for Canada's economy in 2020 by half a per cent.

Oil price futures plunged 30% last week, dragging stock markets and currencies, including the Canadian dollar, down with them, even as a deep freeze strained U.S. energy systems. That drop came on top of a 17% decline in February, due to falling demand for oil due to the virus.

The latest price plunge – the worst since the 1991 Gulf War – was the result of Russia and the Organization of Petroleum Exporting Countries (OPEC), led by Saudi Arabia, failing to agree on oil production cuts.

The COVID-19 outbreak in China – the world’s second-largest oil consumer – had resulted in a dramatic drop in oil demand in that country, and a sudden glut of oil, with the U.S. energy crisis affecting electricity, gas and EV markets.

OPEC has historically been able to moderate global oil prices by controlling output. But when Russia refused to co-operate with OPEC and agree to production cuts, Saudi Arabia’s state-owned company, Aramco, announced it plans to boost its oil output from 9.7 million barrels per day (bpd) to 12.3 million bpd in April.

In response to that announcement, West Texas Intermediate (WTI) prices dropped 18% to below US$34 per barrel while the Canadian Crude Index fell 24% to US$21. Western Canadian Select dropped 39% to US$15.73.

The effect on Alberta oilsands producers was severe and immediate. Cenovus Energy Inc. (TSX:CVE) saw roughly $2 billion in market cap erased on March 9, when its stock dropped by 52%, which came on top of a 12% drop March 6.

The company responded the very next day by announcing it would cut spending by 32% in 2020, suspend its oil-by-rail program and defer expansion projects.

MEG Energy Corp. (TSX:MEG), which suffered a 56% share price drop on March 9, also announced a 20% reduction in its 2020 capital spending plan.

Peter Tertzakian, chief economist for ARC Energy Research Institute, wrote last week that Russia’s plan is to try to hurt U.S. shale oil producers, who have more than doubled U.S. oil production over the past decade.

Anas Alhajji, a global oil analyst, expects that plan could work. Even before the oil price shock, he had predicted the great shale boom in the U.S. was coming to an end.

“Shale production will decline, and the myth of ‘explosive growth’ will end,” he told Business in Vancouver. “The impact is global and Canadian producers might suffer even more if the oil that Saudi Arabia sends to the U.S. is medium and heavy. This might last longer than what people think.”

The question for Alberta is how Canadian producers can continue to operate through a period of cheap oil. Alberta producers do not compete on the global market. They serve a niche market of U.S. heavy oil refiners, and Biden-era policy is seen as potentially more favourable for Canada’s energy sector than alternatives.

“On the positive side, the industry is battle-hardened,” Tertzakian wrote. “Over the past five years, innovative companies have already learned to endure some of the lowest prices in the world.”

But he added that they need WTI prices of US$30 per barrel just to break even.

“But that’s an average break-even threshold for an industry with a wide variation in costs. That means at that level about half the companies can’t pay their bills and half are treading water.”

Just prior to the oil price plunge, the International Energy Agency (IEA) updated its 2020 forecast for global oil consumption from an 825,000 bpd increase in oil consumption to a 90,000 bpd decrease, due to the COVID-19 virus and consequent economic contraction and reduction in travel.

The IEA predicts global oil demand won’t return to “normal” until the second half of 2020. But even if demand does return to pre-virus levels, that doesn’t mean oil prices will – not if Saudi Arabia can sustain increased oil production at low prices, and evolving clean grid priorities could influence the trajectory too.

The oil plunge was greeted in Alberta with alarm. Alberta Premier Jason Kenney warned Alberta is in “uncharted territory” as consumers are urged to lock in rates and said his government might have to review its balanced budget and resort to emergency deficit spending.

While British Columbians – who pay some of the highest gasoline prices in North America – will enjoy lower gasoline prices at a time when prices are usually starting a seasonal spike, B.C.’s economy could feel knock-on effects from a recession in Alberta.

“We sell a lot of inputs, do a lot of trade with Alberta, so it’s important for B.C., Alberta’s economic health,” Peacock said, “and recent tensions over electricity purchase talks underscore that.”

Last week, the Trudeau government announced $1 billion in emergency funding to cope with the virus and waived a one-week waiting period for unemployment insurance.

Germany renewable energy milestone 2019 saw wind, solar, hydropower, and biomass outproduce coal and nuclear, as low gas prices and high CO2 costs under the EU ETS reshaped the electricity mix, per Fraunhofer ISE.

Key Points

It marks H1 2019 when renewables supplied 47.3% of Germany's electricity, surpassing coal and nuclear.

✅ Driven by high CO2 prices and cheap natural gas

✅ Wind and solar output rose; coal generation declined sharply

✅ Flexible gas plants outcompeted inflexible coal units

In Lippendorf, Saxony, the energy supplier EnBW is temporarily taking part of a coal-fired power plant offline. Not because someone ordered it — it simply wasn't paying off. Gas prices are low, CO2 prices are high, and with many hours of sunshine and wind, renewable methods are producing a great deal of electricity as part of Germany's energy transition now reshaping operations. And in the first half of the year there was plenty of sun and wind.

The result was a six-month period in which renewable energy sources, a trend echoed by the EU wind and solar record across the bloc, produced more electricity than coal and nuclear power plants together. For the first time 47.3% of the electricity consumers used came from renewable sources, while 43.4% came from coal-fired and nuclear power plants.

In addition to solar and wind power, renewable sources also include hydropower and biomass. Gas supplied 9.3%, reflecting how renewables are crowding out gas across European power markets, while the remaining 0.4% came from other sources, such as oil, according to figures published by the Fraunhofer Institute for Solar Energy Systems in July.

Fabian Hein from the think tank Agora Energiewende stresses that the situation is only a snapshot in time, with grid expansion woes still shaping outcomes. For example, the first half of 2019 was particularly windy and wind power production rose by around 20% compared to the first half of 2018.

Electricity production from solar panels rose by 6%, natural gas by 10%, while the share of nuclear power in German electricity consumption has remained virtually unchanged despite a nuclear option debate in climate policy.

Coal, on the other hand, declined. Black coal energy production fell by 30% compared to the first half of 2018, lignite fell by 20%. Some coal-fired power plants were even taken off the grid, even as coal still provides about a third of Germany's electricity. It is difficult to say whether this was an effect of the current market situation or whether this is simply part of long-term planning, says Hein.

Activists storm German mine in anti-coal protest

It is clear, however, that an increased CO2 price has made the ongoing generation of electricity from coal more expensive. Gas-fired power plants also emit CO2, but less than coal-fired power plants. They are also more efficient and that's why gas-fired power plants are not so strongly affected by the CO2 price

The price is determined at a European level and covers power plants and energy intensive industries in Europe. Other areas, such as heating or transport are not covered by the CO2 price scheme. Since a reform of CO2 emissions trading in 2017, the price has risen sharply. Whereas in September 2016 it was just over €5 ($5.6), by the end of June 2019 it had climbed to over €26.

Ups and downs

Gas as a raw material is generally more expensive than coal. But coal-fired power plants are more expensive to build. This is why operators want to run them continuously. In times of high demand, and therefore high prices, gas-fired power plants are generally started up, as seen when European power demand hit records during recent heatwaves, since it is worth it at these times.

Gas-fired power plants can be flexibly ramped up and down. Coal-fired power plants take 11 hours or longer to get going. That's why they can't be switched on quickly for short periods when prices are high, like gas-fired power plants. In the first half of the year, however, coal-fired power plants were also ramped up and down more often because it was not always worthwhile to let the power plant run around the clock.

Because gas prices were particularly low in the first half of 2019, some gas-fired power plants were more profitable than coal-fired plants. On June 29, 2019, the gas price at the Dutch trading point TTF was around €10 per megawatt hour. A year earlier, it had been almost €20. This is partly due to the relatively mild winter, as there is still a lot of gas in reserve, confirmed a spokesman for the Federal Association of the Energy and Water Industries (BDEW). There are also several new export terminals for liquefied natural gas. Additionally, weaker growth and trade wars are slowing demand for gas. A lot of gas comes to Europe, where prices are still comparatively high, reported the Handelsblatt newspaper.

The increase in wind and solar power and the decline in nuclear power have also reduced CO2 emissions. In the first half of 2019, electricity generation emitted around 15% less CO2 than in the same period last year, reported BDEW. However, the association demands that the further expansion of renewable energies should not be hampered. The target of 65% renewable energy can only be achieved if the further expansion of renewable energy sources is accelerated.

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.

CO2 Removal Technologies address climate change via negative emissions, including carbon capture, reforestation, soil carbon, biochar, BECCS, DAC, and mineralization, helping meet Paris Agreement targets while managing costs, land use, and infrastructure demands.

Key Points

Methods to extract or sequester atmospheric CO2, combining natural and engineered approaches to limit warming.

✅ Includes reforestation, soil carbon, biochar, BECCS, DAC, mineralization

✅ Balances climate goals with costs, land, energy, and infrastructure

✅ Key to Paris Agreement targets under 1.5-2.0 °C warming

The world is, on average, 1.1 degrees Celsius warmer today than it was in 1850. If this trend continues, our planet will be 2 – 3 degrees hotter by the end of this century, according to the Intergovernmental Panel on Climate Change (IPCC).

The main reason for this temperature rise is higher levels of atmospheric carbon dioxide, which cause the atmosphere to trap heat radiating from the Earth into space. Since 1850, the proportion of CO2 in the air has increased, with record greenhouse gas concentrations documented, from 0.029% to 0.041% (288 ppm to 414 ppm).

This is directly related to the burning of coal, oil and gas, which were created from forests, plankton and plants over millions of years. Back then, they stored CO2 and kept it out of the atmosphere, but as fossil fuels are burned, that CO2 is released. Other contributing factors include industrialized agriculture and slash-and-burn land clearing techniques, and emissions from SF6 in electrical equipment are also concerning today.

Over the past 50 years, more than 1200 billion tons of CO2 have been emitted into the planet's atmosphere — 36.6 billion tons in 2018 alone, though global emissions flatlined in 2019 before rising again. As a result, the global average temperature has risen by 0.8 degrees in just half a century.

Atmospheric CO2 should remain at a minimum
In 2015, the world came together to sign the Paris Climate Agreement which set the goal of limiting global temperature rise to well below 2 degrees — 1.5 degrees, if possible.

The agreement limits the amount of CO2 that can be released into the atmosphere, providing a benchmark for the global energy transition now underway. According to the IPCC, if a maximum of around 300 billion tons were emitted, there would be a 50% chance of limiting global temperature rise to 1.5 degrees. If CO2 emissions remain the same, however, the CO2 'budget' would be used up in just seven years.

According to the IPCC's report on the 1.5 degree target, negative emissions are also necessary to achieve the climate targets.

Using reforestation to remove CO2
One planned measure to stop too much CO2 from being released into the atmosphere is reforestation. According to studies, 3.6 billion tons of CO2 — around 10% of current CO2 emissions — could be saved every year during the growth phase. However, a study by researchers at the Swiss Federal Institute of Technology, ETH Zurich, stresses that achieving this would require the use of land areas equivalent in size to the entire US.

Reforestation has potential to tackle the climate crisis by capturing CO2. But it would require a large amount of space

More humus in the soil
Humus in the soil stores a lot of carbon. But this is being released through the industrialization of agriculture. The amount of humus in the soil can be increased by using catch crops and plants with deep roots as well as by working harvest remnants back into the ground and avoiding deep plowing. According to a study by the German Institute for International and Security Affairs (SWP) on using targeted CO2 extraction as a part of EU climate policy, between two and five billion tons of CO2 could be saved with a global build-up of humus reserves.

Biochar shows promise
Some scientists see biochar as a promising technology for keeping CO2 out of the atmosphere. Biochar is created when organic material is heated and pressurized in a zero or very low-oxygen environment. In powdered form, the biochar is then spread on arable land where it acts as a fertilizer. This also increases the amount of carbon content in the soil. According to the same study from the SWP, global application of this technology could save between 0.5 and two billion tons of CO2 every year.

Storing CO2 in the ground
Storing CO2 deep in the Earth is already well-known and practiced on Norway's oil fields, for example. However, the process is still controversial, as storing CO2 underground can lead to earthquakes and leakage in the long-term. A different method is currently being practiced in Iceland, in which CO2 is sequestered into porous basalt rock to be mineralized into stone. Both methods still require more research, however, with new DOE funding supporting carbon capture, utilization, and storage.

Capturing CO2 to be held underground is done by using chemical processes which effectively extract the gas from the ambient air, and some researchers are exploring CO2-to-electricity concepts for utilization. This method is known as direct air capture (DAC) and is already practiced in other parts of Europe.  As there is no limit to the amount of CO2 that can be captured, it is considered to have great potential. However, the main disadvantage is the cost — currently around €550 ($650) per ton. Some scientists believe that mass production of DAC systems could bring prices down to €50 per ton by 2050. It is already considered a key technology for future climate protection.

Carbon capture facilities are still very expensive and take up a huge amount of space

Another way of extracting CO2 from the air is via biomass. Plants grow and are burned in a power plant to produce electricity. CO2 is then extracted from the exhaust gas of the power plant and stored deep in the Earth, with new U.S. power plant rules poised to test such carbon capture approaches.

The big problem with this technology, known as bio-energy carbon capture and storage (BECCS) is the huge amount of space required. According to Felix Creutzig from the Mercator Institute on Global Commons and Climate Change (MCC) in Berlin, it will therefore only play "a minor role" in CO2 removal technologies.

CO2 bound by rock minerals
In this process, carbonate and silicate rocks are mined, ground and scattered on agricultural land or on the surface water of the ocean, where they collect CO2 over a period of years. According to researchers, by the middle of this century it would be possible to capture two to four billion tons of CO2 every year using this technique. The main challenges are primarily the quantities of stone required, and building the necessary infrastructure. Concrete plans have not yet been researched.

Not an option: Fertilizing the sea with iron
The idea is use iron to fertilize the ocean, thereby increasing its nuturient content, which would allow plankton to grow stronger and capture more CO2. However, both the process and possible side effects are very controversial. "This is rarely treated as a serious option in research," concludes SWP study authors Oliver Geden and Felix Schenuit.

Bay of Fundy Tidal Energy advances as Nova Scotia permits Jupiter Hydro to test floating barge platforms with helical turbines in Minas Passage, supporting renewable power, grid-ready pilots, and green jobs in rural communities.

Key Points

A Nova Scotia tidal energy project using helical turbines to generate clean power and create local jobs.

✅ Permits enable 1-2 MW prototypes near Minas Passage

✅ Floating barge platforms with patented helical turbines

✅ PPA at $0.50/kWh with Nova Scotia Power

An Alberta-based company has been granted permission to try to harness electricity from the powerful tides of the Bay of Fundy.

Nova Scotia has issued two renewable energy permits to Jupiter Hydro.

Backers have long touted the massive energy potential of Fundy's tides -- they are among the world's most powerful -- but large-scale commercial efforts to harness them have borne little fruit so far, even as a Scottish tidal project recently generated enough power to supply nearly 4,000 homes elsewhere.

The Jupiter application says it will use three "floating barge type platforms" carrying its patented technology. The company says it uses helical turbines mounted as if they were outboard motors.

"Having another company test their technology in the Bay of Fundy shows that this early-stage industry continues to grow and create green jobs in our rural communities," Energy and Mines Minister Derek Mombourquette said in a statement.

The first permit allows the company to test a one-megawatt prototype that is not connected to the electricity grid.

The second -- a five-year permit for up to two megawatts -- is renewable if the company meets performance standards, environmental requirements and community engagement conditions.

Mombourquette also authorized a power purchase agreement that allows the company to sell the electricity it generates to the Nova Scotia grid through Nova Scotia Power for 50 cents per kilowatt hour.

On its web site, Jupiter says it believes its approach "will prove to be the most cost effective marine energy conversion technology in the world," even as other regional utilities consider initiatives like NB Power's Belledune concept for turning seawater into electricity.

The one megawatt unit would have screws which are about 5.5 metres in diameter.

The project is required to obtain all other necessary approvals, permits and authorizations.

It will be located near the Fundy Ocean Research Center for Energy in the Minas Passage and will use existing electricity grid connections.

A study commissioned by the Offshore Energy Research Association of Nova Scotia says by 2040, the tidal energy industry could contribute up to $1.7 billion to Nova Scotia's gross domestic product and create up to 22,000 full-time jobs, a transition that some argue should be planned by an independent body to ensure reliability.

Last month, Nova Scotia Power said it now generates 30 per cent of its power from renewables, as the province moves to increase wind and solar projects after abandoning the Atlantic Loop.

The utility says 18 per cent came from wind turbines, nine per cent from hydroelectric and tidal turbines and three per cent by burning biomass across its fleet.

However, over half of the province's electrical generation still comes from the burning of coal or petroleum coke, even as environmental advocates push to reduce biomass use in the mix. Another 13 per cent come from burning natural gas and five per cent from imports.
