As the leader of one of the world's foremost satellite technology companies, John MacDonald spent a lot of time looking at planet Earth from outer space.

Today, at an age when most people of his generation are retired, he's looking in the opposite direction.

MacDonald is co-founder and chair of Day4 Energy, a British Columbia-based solar panel manufacturing company with proprietary technology to offer a booming global market for green energy.

"It's been apparent to me for quite a long time that the world has to evolve to where renewable energy becomes a significant source of our electrical energy and solar, as l like to say, is the king of renewables. It's energy directly from the sun," the 72-year-old MacDonald said in a recent interview at Day4's bustling manufacturing plant in south Burnaby.

A lot of people, particularly Europeans looking for alternatives to fossil fuels, seem to agree.

Day4 commenced manufacturing in 2006 and since then, annual production has quadrupled and is expected to double again within a few months.

This expansion, predicated upon a fundamental reworking of conventional solar technology, is rapid enough to rank Day4 second on The Vancouver Sun's list of the Top 50 fastest-growing companies in B.C.

The B.C. public company's entire 2009 manufacturing output is already sold out, and its patents are already recognized in the United States, the European Union, China, India and Mexico.

The key to its success is a major improvement upon the conventional electrode, or silver wire grid, that sits upon the black background sheet of a solar panel.

Day4's electrode harvests electricity about 20-per-cent more efficiently, in a smaller space, than a conventional solar panel.

In an industry where the manufacturing cost per kilowatt of electricity produced is substantially higher than other types of green power, that's a notable advantage.

MacDonald, an Officer of the Order of Canada, was retired for only a couple of years from his position as chair and CEO of MacDonald Dettwiler, the Vancouver-based satellite imaging and surveillance company, when he had a meeting with prominent Russian physicist Leonid Rubin that convinced him to get back into the business world.

In Moscow for a meeting of the APEC business advisory council, MacDonald was treated by Rubin to a whirlwind look at Russian technological innovation.

MacDonald, himself a rare combination of physicist, engineer, educator and entrepreneur, describes his two-day tour of Russian laboratories and research facilities as "a drink from a technological firehose."

"We were sitting in a coffee shop behind the Bolshoi Theatre," MacDonald recalled in a recent interview at Day4 headquarters in south Burnaby.

"Leonid said to me, 'Of all the things you've seen, which one could we build a business around in Canada?'

"I said, 'It's obvious. Your solar energy project. If you do what you say you can do, and I see absolutely no technical reason why you can't, there's a market.'

"A month later he was in Vancouver. We incorporated the company. This was in May of 2001."

What Rubin did, in essence, was build a better mousetrap.

"This industry has been around for 30-40 years and while they have made huge improvements in the cells themselves, the method of interconnection has not changed in those 30 years. "What Leonid did, is figure out a better way to do it."

Leonid Rubin's son George, already living in Vancouver and a family friend of the MacDonald's, arranged the original meeting of the two men in Moscow.

George Rubin, a physicist who also had business degree, was the "obvious" choice to run the company's day-to-day business, MacDonald said.

By 2002, MacDonald and the Rubins were laying the groundwork for the company.

Leonid Rubin remained in Russia with his technical crew, seeking to turn the electrode prototype into something that could be produced at a commercial level.

"The technical guys were over in Russia and of course the costs were much less than what you could do it for in Canada. When that was done we brought the whole bunch of them over here," MacDonald said.

"They are all here now. Leonid is a landed immigrant along with his wife, and these guys are now the core of the R&D group."

"George and I did the planning and raising the money."

They opened the first manufacturing plant, with total annual capacity of 12 megawatts of solar panels, in the third quarter of 2006.

On July 15, 2008, Day4 announced completion of an expansion that quadrupled manufacturing, from 12 megawatts to 47 megawatts.

They aren't done yet.

The company expects another doubling of production, to 97 megawatts by year's end.

There was more good news. On July 30, Day4 announced successful trials for its next-generation electrode, which is 25 per cent more efficient than its current model.

The company's bottom line is still a work in progress, given the infusions of cash necessary to support expansion.

The company reported a 2.5-per-cent gross profit, $400,000 in second quarter 2008 compared to two per cent or $300,000 in the first quarter — and a negative gross margin of 21 per cent for fiscal 2007.

Day4's most recent quarterly report, for June 30, reported total second quarter revenue reached $15 million compared to $13.5 million in the first three months of the year — and $3.1 million in second quarter 2007.

The company noted that the 2008 second quarter jump was achieved despite unchanged production capacity, and pointed to an eight-per-cent efficiency gain in its manufacturing process.

In fiscal 2007, Day4's revenue increased 10 times, from $1.9 million in 2006 to $20.9 million last year.

The company hopes to be in the black on a net revenue basis, by the end of this year.

"This is a very scalable process and we can keep expanding it to meet the market," MacDonald said. "Of course these days with all that's going on in the financial world you have to take a deep breath, but the company is in good shape. I'm not worrying about it."

NRC Begins Special Inspection at River Bend Nuclear Power Plant

NRC Special Inspection at River Bend reviews failures of portable emergency diesel generators, nuclear safety measures, and Entergy Operations actions after Fukushima; off-site power loss readiness, remote COVID-19 oversight, and corrective action plans are assessed.

 

Key Points

An NRC review of generator test failures at River Bend, assessing nuclear safety, root causes, and corrective actions.

✅ Evaluates failures of portable emergency diesel generators

✅ Reviews causal analyses and adequacy of corrective actions

✅ Remote COVID-19 oversight; public report expected within 45 days

 

The Nuclear Regulatory Commission has begun a special inspection at the River Bend nuclear power plant, part of broader oversight that includes the Turkey Point renewal application, to review circumstances related to the failure of five portable emergency diesel generators during testing. The plant, operated by Entergy Operations, is located in St. Francisville, La., as nations like France outage risks continue to highlight broader reliability concerns.

The generators are used to supply power to plant systems in the event of a prolonged loss of off-site electrical power coupled with a failure of the permanently installed emergency generators, a concern underscored by incidents such as the SC nuclear plant leak that shut down production for weeks. These portable generators were acquired as part of the facility's safety enhancements mandated by the NRC following the 2011 accident at the Fukushima Dai-ichi facility in Japan, and amid constraints like France limiting output from warm rivers, the emphasis on resilience remains.

The three-member NRC team will develop a chronology of the test failures and evaluate the licensee's causal analyses and the adequacy of corrective actions, informed by lessons from cases like Davis-Besse closure stakes that underscore risk management.

Due to the COVID-19 pandemic, they will complete most of their work remotely, while other regions address constraints such as high river temperatures limiting output for nuclear stations. An inspection report documenting the team's findings, released as global nuclear project milestones continue across the sector, will be publicly available within 45 days of the end of the inspection.

Coronavirus impacts dismantling of Germany's Philippsburg nuclear plant

Philippsburg Demolition Delay: EnBW postpones controlled cooling-tower blasts amid the coronavirus pandemic, affecting decommissioning timelines in Baden-Wurttemberg and grid expansion for a transformer station to route renewable power and secure supply in southern Germany.

 

Key Points

EnBW's COVID-19 delay of Philippsburg cooling-tower blasts, affecting decommissioning and grid plans.

✅ Controlled detonation shifted to mid-May at earliest

✅ Demolition links to transformer station for north-south grid

✅ Supports security of supply in southern Germany

 

German energy company EnBW said the coronavirus outbreak has impacted plans to dismantle its Philippsburg nuclear power plant in Baden-Wurttemberg, southwest Germany, amid plans to phase out coal and nuclear nationally.

The controlled detonation of Phillipsburg's cooling towers will now take place in mid-May at the earliest, subject to coordination as Germany debates whether to reconsider its nuclear phaseout in light of supply needs.

However, EnBW said the exact demolition date depends on many factors - including the further development in the coronavirus pandemic and ongoing climate policy debates about energy choices.

Philippsburg 2, a 1402MWe pressurised water reactor unit permanently shut down on 31 December 2019, as part of Germany's broader effort to shut down its remaining reactors over time.

At the end of 2019, the Ministry of the Environment gave basic approval for decommissioning and dismantling of unit 2 of the Philippsburg nuclear power plant, inluding explosive demolition of the colling towers. Since then EnBW has worked intensively on getting all the necessary formal steps on the way and performing technical and logistical preparatory work, even as discussions about a potential nuclear resurgence continue nationwide.

“The demolition of the cooling towers is directly related to future security of supply in southern Germany. We therefore feel obliged to drive this project forward," said Jörg Michels head of the EnBW nuclear power division.

The timely removal of the cooling towers is important as the area currently occupied by nuclear plant components is needed for a transformer station for long-distance power lines, an issue underscored during the energy crisis when Germany temporarily extended nuclear power to bolster supply. These will transport electricity from renewable sources in the north to industrial centres in the south.

As of early 2020, there six nuclear reactors in operation in Germany, even as the country turned its back on nuclear in subsequent years. According to research institute Fraunhofer ISE, nuclear power provided about 14% of Germany's net electricity in 2019, less than half of the figure for 2000.

Should California Fund Biofuels or Electric Vehicles?

California Biofuels vs EV Subsidies examines tradeoffs in decarbonization, greenhouse gas reductions, clean energy deployment, charging infrastructure, energy security, lifecycle emissions, and transportation sector policy to meet climate goals and accelerate sustainable mobility.

 

Key Points

Policy tradeoffs weighing biofuels and EVs to cut GHGs, boost energy security, and advance clean transportation.

✅ Near-term blending cuts emissions from existing fleets

✅ EVs scale with a cleaner grid and charging buildout

✅ Lifecycle impacts and costs guide optimal subsidy mix

 

California is at the forefront of the transition to a greener economy, driven by its ambitious goals to reduce greenhouse gas emissions and combat climate change. As part of its strategy, the state is grappling with the question of whether it should subsidize out-of-state biofuels or in-state electric vehicles (EVs) to meet these goals. Both options come with their own sets of benefits and challenges, and the decision carries significant implications for the state’s environmental, economic, and energy landscapes.

The Case for Biofuels

Biofuels have long been promoted as a cleaner alternative to traditional fossil fuels like gasoline and diesel. They are made from organic materials such as agricultural crops, algae, and waste, which means they can potentially reduce carbon emissions in comparison to petroleum-based fuels. In the context of California, biofuels—particularly ethanol and biodiesel—are viewed as a way to decarbonize the transportation sector, which is one of the state’s largest sources of greenhouse gas emissions.

Subsidizing out-of-state biofuels can help California reduce its reliance on imported oil while promoting the development of biofuel industries in other states. This approach may have immediate benefits, as biofuels are widely available and can be blended with conventional fuels to lower carbon emissions right away. It also allows the state to diversify its energy sources, improving energy security by reducing dependency on oil imports.

Moreover, biofuels can be produced in many regions across the United States, including rural areas. By subsidizing out-of-state biofuels, California could foster economic development in these regions, creating jobs and stimulating agricultural innovation. This approach could also support farmers who grow the feedstock for biofuel production, boosting the agricultural economy in the U.S.

However, there are drawbacks. The environmental benefits of biofuels are often debated. Critics argue that the production of biofuels—particularly those made from food crops like corn—can contribute to deforestation, water pollution, and increased food prices. Additionally, biofuels are not a silver bullet in the fight against climate change, as their production and combustion still release greenhouse gases. When considering whether to subsidize biofuels, California must also account for the full lifecycle emissions associated with their production and use.

The Case for Electric Vehicles

In contrast to biofuels, electric vehicles (EVs) offer a more direct pathway to reducing emissions from transportation. EVs are powered by electricity, and when coupled with renewable energy sources like solar or wind power, they can provide a nearly zero-emission solution for personal and commercial transportation. California has already invested heavily in EV infrastructure, including expanding its network of charging stations and exploring how EVs can support grid stability through vehicle-to-grid approaches, and offering incentives for consumers to purchase EVs.

Subsidizing in-state EVs could stimulate job creation and innovation within California's thriving clean-tech industry, with other states such as New Mexico projecting substantial economic gains from transportation electrification, and the state has already become a hub for electric vehicle manufacturers, including Tesla, Rivian, and several battery manufacturers. Supporting the EV industry could further strengthen California’s position as a global leader in green technology, attracting investment and fostering growth in related sectors such as battery manufacturing, renewable energy, and smart grid technology.

Additionally, the environmental benefits of EVs are substantial. As the electric grid becomes cleaner with an increasing share of renewable energy, EVs will become even greener, with lower lifecycle emissions than biofuels. By prioritizing EVs, California could further reduce its carbon footprint while also achieving its long-term climate goals, including reaching carbon neutrality by 2045.

However, there are challenges. EV adoption in California remains a significant undertaking, requiring major investments in infrastructure as they challenge state power grids in the near term, technology, and consumer incentives. The cost of EVs, although decreasing, still remains a barrier for many consumers. Additionally, there are concerns about the environmental impact of lithium mining, which is essential for EV batteries. While renewable energy is expanding, California’s grid is still reliant on fossil fuels to some degree, and in other jurisdictions such as Canada's 2019 electricity mix fossil generation remains significant, meaning that the full emissions benefit of EVs is not realized until the grid is entirely powered by clean energy.

A Balancing Act

The debate between subsidizing out-of-state biofuels and in-state electric vehicles is ultimately a question of how best to allocate California’s resources to meet its climate and economic goals. Biofuels may offer a quicker fix for reducing emissions from existing vehicles, but their long-term benefits are more limited compared to the transformative potential of electric vehicles, even as some analysts warn of policy pitfalls that could complicate the transition.

However, biofuels still have a role to play in decarbonizing hard-to-abate sectors like aviation and heavy-duty transportation, where electrification may not be as feasible in the near future. Thus, a mixed strategy that includes both subsidies for EVs and biofuels may be the most effective approach.

Ultimately, California’s decision will likely depend on a combination of factors, including technological advancements, 2021 electricity lessons, and the pace of renewable energy deployment, and the state’s ability to balance short-term needs with long-term environmental goals. The road ahead is not easy, but California's leadership in clean energy will be crucial in shaping the nation’s response to climate change.

Are we ready for electric tractors?

Electric tractors are surging, with battery-powered models, grid-tethered JD GridCON, and solar-charged designs delivering autonomous guidance, high efficiency, low maintenance, quiet operation, robust PTO compatibility, and durability for sustainable, precision agriculture.

 

Key Points

Electric tractors use battery or grid power to run implements with high efficiency, low noise, and minimal maintenance.

✅ Battery, grid-tethered, or solar-charged power options

✅ Lower operating costs, reduced noise, fewer moving parts

✅ Autonomous guidance, PTO compatibility, and quick charging

 

Car and truck manufacturers are falling off the fossil fuel bandwagon in droves and jumping on the electric train.

Now add tractors to that list.

Every month, another e-tractor announcement comes across our desks. Environmental factors drive this trend, along with energy efficiency, lower maintenance, lower noise level and motor longevity, and even autonomous weed-zapping robots are emerging.

Let’s start with the Big Daddy of them all, the 400 horsepower JD GridCON. This tractor is not a hybrid and it has no hassle with batteries. The 300 kilowatts of power come to the GridCON through a 1,000 metre extension cord connected to the grid, including virtual power plants or an off-field generator. A reel on the tractor rolls the cable in and out. The cable is guided by a robotic arm to prevent the tractor from running over it.

It uses a 700 volt DC bus for electric power distribution onboard and for auxiliary implements. It uses a cooling infrastructure for off-board electrical use. Total efficiency of the drive train is around 85 percent. A 100 kilowatt electric motor runs the IVT transmission. There’s an auxiliary outlet for implements powered by an electric motor up to 200 kW.

GridCON autonomously follows prescribed routes in the field at speeds up to 12 m.p.h., leveraging concepts similar to fleet management solutions for coordination. It can also be guided manually with a remote control when manoeuvring the tractor to enter a field. Empty weight is 8.5 tonnes, which is about the same as a 6195R but with double the power. Deere engineers say it will save about 50 percent in operating costs compared to battery powered tractors.

Solectrac
Two California-built all-battery powered tractors are finally in full production. While the biggest is only 40 horsepower, these are serious tractors that may foretell the future of farm equipment.

The all-electric 40 h.p. eUtility tractor is based on a 1950s Ford built in India. Solectrac is able to buy the bare tractor without an engine, so it can create a brand new electric tractor with no used components for North American customers. One tractor has already been sold to a farmer in Ontario. | Solectrac photo
The tractors are built by Solectrac, owned by inventor Steve Heckeroth, who has been doing electric conversions on cars, trucks, race cars and tractors for 25 years. He said there are three main reasons to take electric tractors seriously: simplicity, energy efficiency and longevity.

“The electric motor has only one moving part, unlike small diesel engines, which have over 300 moving parts,” Heckeroth said, adding that Solectrac tractors are not halfway compromise hybrids but true electric machines that get their power from the sun or the grid, particularly in hydro-rich regions like Manitoba where clean electricity is abundant, whichever is closest.

Neither tractor uses hydraulics. Instead, Heckeroth uses electric linear actuators. The ones he installs provide 1,000 pounds of dynamic load and 3,000 lb. static loads. He uses linear actuators because they are 20 times more efficient than hydraulics.

The eUtility and eFarmer are two-wheel drive only, but engineers are working on compact four-wheel drive electric tractors. Each tractor carries a price tag of US$40,000. Because production numbers are still limited, both tractors are available on a first to deposit basis. One e-tractor has already been sold and delivered to a farmer in Ontario.

The eUtility is a 40 h.p. yard tractor that accepts all Category 1, 540 r.p.m. power take-off implements on the rear three-point hitch, except those requiring hydraulics. An optional hydraulic pump can be installed for $3,000 for legacy implements that require hydraulics. For that price, a dedicated electricity believer might instead consider converting the implement to electric.

“The eUtility is actually a converted new 1950s Ford tractor made in a factory in India that was taken over after the British were kicked out in 1948,” Heckeroth said.

“I am able to buy only the parts I need and then add the motor, controller and batteries. I had to go to India because it’s one of the few places that still makes geared transmissions. These transmissions work the best for electric tractors. Gear reduction is necessary to keep the motor in the most efficient range of about 2,000 r.p.m. It has four gears with a high and low range, which covers everything from creep to 25 m.p.h.

On his eUtility, a single 30 kWh onboard battery pack provides five to eight hours of run time, depending on loads. It can carry two battery packs. The Level 2 quick charge gives an 80 percent charge for one pack in three hours. Two packs can receive a full charge overnight with support from home batteries like Powerwall for load management.

The integrated battery management system protects the batteries during charging and discharging, while backup fuel cell chargers can keep storage healthy in remote deployments. Batteries are expected to last about 10 years, depending on the number of operating cycles and depth of discharge.

Exchangeable battery packs are available to keep the tractor running through the full work day. These smaller 20 kWh packs can be mounted on the rear hitch to balance the weight of the optional front loader or carried in the optional front loader to balance the weight of heavy implements mounted on the rear hitch.

The second tractor is the 20 kWh eFarmer, which features high visibility for row crop farms at a fraction of the cost of diesel fuel tractors. The 30 h.p. eFarmer is basically just a tube frame with the necessary components attached. A simple joystick controls steering, speed and brakes.

Harvest
Introduced to the North American public this spring by Motivo Engineering in California, the Harvest tractor is simply a big battery on wheels. The complex electrical system takes power in through a variety of renewable energy sources, such as solar panels with smart solar inverters enabling optimized PV integration, water wheels, wind turbines or even intermittent electrical grids. It stores electrical power on-board and delivers it when and where required, putting power out to a large number of electrical tools and farm implements. It operates in AC or DC modes.

Electricity use actually increased during 2018 Earth Hour, BC Hydro

Earth Hour BC highlights BC Hydro data on electricity use, energy savings, and participation in the Lower Mainland and Vancouver Island amid climate change and hydroelectric power dynamics.

 

Key Points

BC observance tracking BC Hydro electricity use and conservation during Earth Hour, amid hydroelectric power dominance.

✅ BC Hydro reports rising electricity use during Earth Hour 2018

✅ Savings fell from 2% in 2008 to near zero province-wide

✅ Hydroelectric grid yields low GHG emissions in BC

 

For the first time since it began tracking electricity use in the province during Earth Hour, BC Hydro said customers used more power during the 60-minute period when lights are expected to dim, mirroring all-time high electricity demand seen recently.

The World Wildlife Fund launched Earth Hour in Sydney, Australia in 2007. Residents and businesses there turned off lights and non-essential power as a symbol to mark the importance of combating climate change.

The event was adopted in B.C. the next year and, as part of that, BC Hydro began tracking the megawatt hours saved.

In 2008, residents and businesses achieved a two per cent savings in electricity use. But since then, BC Hydro says the savings have plummeted.

The event was adopted in B.C. the next year and, as part of that, BC Hydro began tracking the megawatt hours saved.

In 2008, residents and businesses achieved a two per cent savings in electricity use. But since then, BC Hydro says the savings have plummeted, as record-breaking demand in 2021 and beyond changed consumption patterns.

 

Lights on

For Earth Hour this year, which took place 8:30-9:30 p.m. on March 24, BC Hydro says electricity use in the Lower Mainland increased by 0.5 per cent, even as it activated a winter payment plan to help customers manage bills. On Vancouver Island it increased 0.6 per cent.

In the province's southern Interior and northern Interior, power use remained the same during the event.

On Friday, the utility released a report called: "lights out". Why Earth Hour is dimming in BC. which explores the decline of energy savings related to Earth Hour in the province.

The WWF says the way in which hydro companies track electricity savings during Earth Hour is not an accurate measure of participation, and tracking of emerging loads like crypto mining electricity use remains opaque, and noted that more countries than ever are turning off lights for the event.

For 2018, the WWF shifted the focus of Earth Hour to the loss of wildlife across the globe.

BC Hydro says in its report that the symbolism of Earth Hour is still important to British Columbians, but almost all power generation in B.C. is hydroelectric, though recent drought conditions have required operational adjustments, and only accounts for one per cent of greenhouse gas emissions.

Collectively, the storage facilities will enhance grid operations, increase efficiencies and improve overall reliability for surrounding communities, with virtual power plant programs offering a model for coordinating distributed resources.

They will also provide important backup generation during power outages, a service that is becoming increasingly important with the number and intensity of storms that have recently impacted the state.

As the grid manager and operator, DEF can maximize the versatility of battery energy storage systems (BESS) to include multiple customer and electric system benefits such as balancing energy demand, managing intermittent resources, increasing energy security and deferring traditional power grid upgrades.

These benefits help reduce costs for customers and increase operational efficiencies.

The 11-megawatt (MW) Trenton lithium-based battery facility will be located 30 miles west of Gainesville in Gilchrist County. The energy storage project will continue to improve power reliability using newer technologies.

The 5.5-MW Cape San Blas lithium-based battery facility will be located approximately 40 miles southeast of Panama City in Gulf County. The project will provide additional power capacity to meet our customers' rising energy demand in the area. This project is an economical alternative to replacing distribution equipment necessary to accommodate local load growth.

The 5.5-MW Jennings lithium-based battery facility will be located 1.5 miles south of the Florida-Georgia border in Hamilton County. The project will continue to improve power reliability through energy storage as an alternative solution to installing new and more costly distribution equipment.

Currently the company plans to complete all three projects by the end of 2020.

"These battery projects provide electric system benefits that will help improve local reliability for our customers and provide significant energy services to the power grid," said Catherine Stempien, Duke Energy Florida state president. "Duke Energy Florida will continue to identify opportunities in battery storage technology which will deliver efficiency improvements to our customers."

 

Additional renewables projects

As part of DEF's commitment to renewables, the company is investing an estimated $1 billion to construct or acquire a total of 700 MW of cost-effective solar power facilities and 50 MW of battery storage through 2022.

Duke Energy is leading the industry deployment of battery technology, with SDG&E's Emerald Storage project underscoring broader adoption across the sector today. Last fall, the company and University of South Florida St. Petersburg unveiled a Tesla battery storage system that is connected to a 100-kilowatt (kW) solar array – the first of its kind in Florida.

This solar-battery microgrid system manages the energy captured by the solar array, situated on top of the university's parking garage, and similar low-income housing microgrid financing efforts are expanding access. The solar array was constructed three years ago through a $1 million grant from Duke Energy. The microgrid provides a backup power source during a power outage for the parking garage elevator, lights and electric vehicle charging stations. Click here to learn more.

In addition to expanding its battery storage technology and solar investments, DEF is investing in transportation electrification to support the growing U.S. adoption of electric vehicles (EV), including EV charging infrastructure, 530 EV charging stations and a modernized power grid to deliver the diverse and reliable energy solutions customers want and need.
