The proverbial light bulb went on for me a year ago when both my husband and I woke up with splitting headaches after leaving our ensuite bathroom light on all night.

Our headaches were identical, both feeling pain behind our eyes and in our temples.

I don’t usually suffer from headaches and I didn’t end up with a cold of flu to explain the head pain. The only answer we both came up with was the Compact Fluorescent Lights (CFLs) shining from our ensuite must have irritated us. We had felt a feeling of being ‘unwell’ before, while reading at the kitchen table where we had also switched to CFL lighting.

The ‘green’ marketing machine has promoted CFLs like no other energy saving product out there. We bought in and switched most of our lighting in our household under the idea we were helping the environment.

Our headaches and our realization came months before new tests revealed what dirty electricity these bulbs might be giving off. The mercury-based bulbs, that have been pushed on us by government advertising and rebates by BC Hydro as the saviour to Earth as we know it, give off UV radiation.

They may emit up to 200 times the dirty energy, or radiation, of the incandescent bulbs most of us have got rid of, say some scientists.

The rub is the Canadian government wants to eliminate incandescent bulbs by 2012, leaving our workplaces, malls, offices, grocery stores and homes full of CFL lighting. At Trinity Western University, for example, they have changed out almost all of the incandescent light bulbs in the dorms to energy-saving CFLs.

Energy-saving light bulbs are the most common way to go green at home, according to Statistics CanadaÂ’s latest Households and the Environment survey, with 84 per cent of households in 2007 having at least one CFL bulb.

Even David Suzuki promotes CFLs, with a picture of one right on the front page of his website.

I e-mailed my concerns about the harmful radiation coming from CFLs. The Suzuki Foundation replied that it supports the bulbs because they are much more energy efficient, thereby better for Mother Earth.

“New studies have shown that CFLs can be problematic for people with certain skin conditions. This can be easily avoided by not using the bulbs where one would be spending more than an hour a day within 30 cm of the bulb or by using an encapsulated bulb,” writes Ryan Kadowaki, of the David Suzuki Foundation.

“Health Canada is currently testing CFLs to ensure they are not posing any health risks. There are currently no peer-reviewed scientific studies linking CFLs with the medical problems mentioned on the show.”

The show he is referring to is Global TVÂ’s 16 by 9, which had several scientists run tests, showing the bulbs emitting 200 times the dirty electricity compared to incandescents.

Then a memo from BC Hydro to the B.C. Utilities Commission stated that the switch over to CFL bulbs is causing people to turn up the heat in fall and winter.

In the report and speaking to CBC, BC Hydro said CFLs do increase greenhouse gas emmissions because of the loss of heat coming from incandescent light bulbs throughout peopleÂ’s homes.

Then on March 5, BC Hydro posted a ‘fact and myth’ page promoting the use of CFLs.

CFLs do add greenhouse gas emissions because of the loss of heat from incandescent bulbs, the website says. But incandescent light bulbs are so inefficient at producing light, that 95 per cent of the electricity they use goes towards producing heat, said BC Hydro.

Even after this report about loss of heating, the David Suzuki Foundation disputes the claim that incandescents heat homes, saying the heat coming from these bulbs is minimal, given most of our lighting is in the ceiling and heat rises.

The Suzuki Foundation admits that CFLs arenÂ’t the ideal bulb to have in the house, but until LED technology puts out household bulbs and lighting, CFLs are the best interim solution to help the environment, said Nicolas Harp, climate and energy policy director for the David Suzuki Foundation.

When I was doing a story on the hype around banning plastic bags six months ago, I phoned the Recycling Council of B.C. to ask where bags get recycled (turns out at a Burnaby plant). I also wanted to know how many end up in the landfill. The spokesperson said it was CFL bulbs ending up in the landfill that people should be more concerned about — not plastic bags.

The reason?

The amount of mercury ending up in the landfill from CFL bulbs. Oh, and by the way, if one of these CFLs happen to break inside your home, Health Canada advises you to ventilate the room and not inhale the mercury and then wear rubber gloves and not touch the bulbs.

Health Canada also warns that people with lupus, light sensitivity and people prone to headaches may find ill effects from the UV radiation coming from CFLs.

So to recap, according to tests done by some scientists, CFLs emit 200 times the radiation as the old bulbs, cause some people headaches, others with skin conditions, red rashes and possible aches and pains depending on sensitivity levels.

They put more mercury into the environment than any other type of bulb — but the government wants every mall, office and home to be full of CFLs by 2012?

Come to your own conclusions and make your own decisions.

As for me, IÂ’ve switched back to incandescents in hopes LED lights will come out soon.

California's Next Electricity Headache Is a Looming Shortage

California Electricity Reserve Mandate requires 3.3 GW of new capacity to bolster grid reliability amid solar power volatility, peak demand, and wildfire-driven blackouts, as CPUC directs PG&E, Edison, and Sempra to procure resource adequacy.

 

Key Points

A CPUC order for utilities to add 3.3 GW of reserves, safeguarding grid reliability during variable renewables and peaks

✅ 3.3 GW procurement to meet resource adequacy targets

✅ Focus on grid reliability during peak evening demand

✅ Prioritizes renewables, storage; limits new fossil builds

 

As if California doesn’t have enough problems with its electric service, now state regulators warn the state may be short on power supplies by 2021 if utilities don’t start lining up new resources now.

In the hopes of heading off a shortfall as America goes electric, the California Public Utilities Commission has ordered the state’s electricity providers to secure 3.3 additional gigawatts of reserve supplies. That’s enough to power roughly 2.5 million homes. Half of it must be in place by 2021 and the rest by August 2023.

The move comes as California is already struggling to accommodate increasingly large amounts of solar power that regularly send electricity prices plunging below zero and force other generators offline so the region’s grid doesn’t overload. The state is also still reeling from a series of deliberate mass blackouts that utilities imposed last month to keep their power lines from sparking wildfires amid strong winds. And its largest power company, PG&E Corp., went bankrupt in January.

Now as natural gas-fired power plants retire under the state’s climate policies, officials are warning the state could run short on electricity on hot evenings, when solar production fades and commuters get home and crank up their air conditioners. “We have fewer resources that can be quickly turned on that can meet those peaks,” utilities commission member Liane Randolph said Thursday before the panel approved the order to beef up reserves.

The 3.3 gigawatts that utilities must line up is in addition to a state rule requiring them to sign contracts for 15% more electricity than they expect to need. Some critics question the need for added supplies, particularly after the state went on a plant-building boom in the 2000s.

But California’s grid managers say the risk of a shortfall is real and could be as high as 4.7 gigawatts, especially during heat waves that test the grid again. Mark Rothleder, with the California Independent System Operator, said the 15% cushion is a holdover from the days before big solar and wind farms made the grid more volatile. Now it may need to be increased, he said.

“We’re not in that world anymore,” said Rothleder, the operator’s vice president of state regulatory affairs. “The complexity of the system and the resources we have now are much different.”

The state’s three major utilities, PG&E, Edison International and Sempra Energy, will be largely responsible for securing new supplies. The commission banned fossil fuels from being used at any new power generators built to meet the requirement — though it left the door open for expansions at existing ones.

Some analysts argue California is exporting its energy policies to Western states, making electricity more costly and less reliable.

PG&E said in an emailed statement that it was pleased the commission didn’t adopt an earlier proposal to require 4 gigawatts of additional resources. Edison similarly said it was “supportive.” Sempra didn’t immediately respond with comment.

 

Extending Deadlines

The pending plant closures are being hastened by a 2020 deadline requiring California’s coastal generators to stop using aging seawater-cooling systems. Some gas-fired power plants have said they’ll simply close instead of installing costly new cooling systems. So the commission on Thursday also asked California water regulators to extend the deadline for five plants.

The Sierra Club, meanwhile, called on regulators to turn away from fossil fuels altogether, saying their decision Thursday “sets California back on its progress toward a clean energy future.”

The move to push back the deadline also faces opposition from neighboring towns. Redondo Beach Mayor Bill Brand, whose city is home to one of the plants in line for an extension, told the commission it wasn’t necessary, since California utilities already have plenty of electricity reserves.

“It’s just piling on to that reserve margin,” Brand said.

Its Electric Grid Under Strain, California Turns to Batteries

California Battery Storage is transforming grid reliability as distributed energy, solar-plus-storage, and demand response mitigate rolling blackouts, replace peaker plants, and supply flexible capacity during heat waves and evening peaks across utilities and homes.

 

Key Points

California Battery Storage uses distributed and utility batteries to stabilize power, shift solar, and curb blackouts.

✅ Supplies flexible capacity during peak demand and heat waves

✅ Enables demand response and replaces gas peaker plants

✅ Aggregated assets form virtual power plants for grid support

 

Last month as a heat wave slammed California, state regulators sent an email to a group of energy executives pleading for help to keep the lights on statewide. “Please consider this an urgent inquiry on behalf of the state,” the message said.

The manager of the state’s grid was struggling to increase the supply of electricity because power plants had unexpectedly shut down and demand was surging. The imbalance was forcing officials to order rolling blackouts across the state for the first time in nearly two decades.

What was unusual about the emails was whom they were sent to: people who managed thousands of batteries installed at utilities, businesses, government facilities and even homes. California officials were seeking the energy stored in those machines to help bail out a poorly managed grid and reduce the need for blackouts.

Many energy experts have predicted that batteries could turn homes and businesses into mini-power plants that are able to play a critical role in the electricity system. They could soak up excess power from solar panels and wind turbines and provide electricity in the evenings when the sun went down or after wildfires and hurricanes, which have grown more devastating because of climate change in recent years. Over the next decade, the argument went, large rows of batteries owned by utilities could start replacing power plants fueled by natural gas.

But that day appears to be closer than earlier thought, at least in California, which leads the country in energy storage. During the state’s recent electricity crisis, more than 30,000 batteries supplied as much power as a midsize natural gas plant. And experts say the machines, which range in size from large wall-mounted televisions to shipping containers, will become even more important because utilities, businesses and homeowners are investing billions of dollars in such devices.

“People are starting to realize energy storage isn’t just a project or two here or there, it’s a whole new approach to managing power,” said John Zahurancik, chief operating officer at Fluence, which makes large energy storage systems bought by utilities and large businesses. That’s a big difference from a few years ago, he said, when electricity storage was seen as a holy grail — “perfect, but unattainable.”

On Friday, Aug. 14, the first day California ordered rolling blackouts, Stem, an energy company based in the San Francisco Bay Area, delivered 50 megawatts — enough to power 20,000 homes — from batteries it had installed at businesses, local governments and other customers. Some of those devices were at the Orange County Sanitation District, which installed the batteries to reduce emissions by making it less reliant on natural gas when energy use peaks.

John Carrington, Stem’s chief executive, said his company would have provided even more electricity to the grid had it not been for state regulations that, among other things, prevent businesses from selling power from their batteries directly to other companies.

“We could have done two or three times more,” he said.

The California Independent System Operator, which manages about 80 percent of the state’s grid, has blamed the rolling blackouts on a confluence of unfortunate events, including extreme weather impacts on the grid that limited supply: A gas plant abruptly went offline, a lack of wind stilled thousands of turbines, and power plants in other states couldn’t export enough electricity. (On Thursday, the grid manager urged Californians to reduce electricity use over Labor Day weekend because temperatures are expected to be 10 to 20 degrees above normal.)

But in recent weeks it has become clear that California’s grid managers also made mistakes last month, highlighting the challenge of fixing California’s electric grid in real time, that were reminiscent of an energy crisis in 2000 and 2001 when millions of homes went dark and wholesale electricity prices soared.

Grid managers did not contact Gov. Gavin Newsom’s office until moments before it ordered a blackout on Aug. 14. Had it acted sooner, the governor could have called on homeowners and businesses to reduce electricity use, something he did two days later. He could have also called on the State Department of Water Resources to provide electricity from its hydroelectric plants.

Weather forecasters had warned about the heat wave for days. The agency could have developed a plan to harness the electricity in numerous batteries across the state that largely sat idle while grid managers and large utilities such as Pacific Gas & Electric scrounged around for more electricity.

That search culminated in frantic last-minute pleas from the California Public Utilities Commission to the California Solar and Storage Association. The commission asked the group to get its members to discharge batteries they managed for customers like the sanitation department into the grid. (Businesses and homeowners typically buy batteries with solar panels from companies like Stem and Sunrun, which manage the systems for their customers.)

“They were texting and emailing and calling us: ‘We need all of your battery customers giving us power,’” said Bernadette Del Chiaro, executive director of the solar and storage association. “It was in a very last-minute, herky-jerky way.”

At the time of blackouts on Aug. 14, battery power to the electric grid climbed to a peak of about 147 megawatts, illustrating how virtual power plants can rapidly scale, according to data from California I.S.O. After officials asked for more power the next day, that supply shot up to as much as 310 megawatts.

Had grid managers and regulators done a better job coordinating with battery managers, the devices could have supplied as much as 530 megawatts, Ms. Del Chiaro said. That supply would have exceeded the amount of electricity the grid lost when the natural gas plant, which grid managers have refused to identify, went offline.

Officials at California I.S.O. and the public utilities commission said they were working to determine the “root causes” of the crisis after the governor requested an investigation.

Grid managers and state officials have previously endorsed the use of batteries, using AI to adapt as they integrate them at scale. The utilities commission last week approved a proposal by Southern California Edison, which serves five million customers, to add 770 megawatts of energy storage in the second half of 2021, more than doubling its battery capacity.

And Mr. Zahurancik’s company, Fluence, is building a 400 megawatt-hour battery system at the site of an older natural gas power plant at the Alamitos Energy Center in Long Beach. Regulators this week also approved a plan to extend the life of the power plant, which was scheduled to close at the end of the year, to support the grid.

But regulations have been slow to catch up with the rapidly developing battery technology.

Regulators and utilities have not answered many of the legal and logistical questions that have limited how batteries owned by homeowners and businesses are used. How should battery owners be compensated for the electricity they provide to the grid? Can grid managers or utilities force batteries to discharge even if homeowners or businesses want to keep them charged up for their own use during blackouts?

During the recent blackouts, Ms. Del Chiaro said, commercial and industrial battery owners like Stem’s customers were compensated at the rates similar to those that are paid to businesses to not use power during periods of high electricity demand. But residential customers were not paid and acted “altruistically,” she said.

California scorns fossil fuel but can't keep the lights on without it

California fossil fuel grid reliability plan addresses heat wave demand, rolling blackouts, and grid stability by temporarily procuring gas generation while accelerating renewables, storage, and transmission to meet clean energy and carbon-neutral targets by 2045.

 

Key Points

A stop-gap policy to prevent blackouts by buying fossil power while fast-tracking renewables, storage, and grid upgrades.

✅ Temporary procurement of gas to avoid rolling blackouts

✅ Accelerates renewables, storage, transmission permitting

✅ Aims for carbon neutrality by 2045 without new gas plants

 

California wants to quit fossil fuels. Just not yet Faced with a fragile electrical grid and the prospect of summertime blackouts, the state agreed to put aside hundreds of millions of dollars to buy power from fossil fuel plants that are scheduled to shut down as soon as next year.

That has prompted a backlash from environmental groups and lawmakers who say Democratic Gov. Gavin Newsom’s approach could end up extending the life of gas plants that have been on-track to close for more than a decade and could threaten the state’s goal to be carbon neutral by 2045.

“The emphasis that the governor has been making is ‘We’re going to be Climate Leaders; we’re going to do 100 percent clean energy; we’re going to lead the nation and the world,’” said V. John White, executive director of the Sacramento-based Center for Energy Efficiency and Renewable Technologies, a non-profit group of environmental advocates and clean energy companies. “Yet, at least a part of this plan means going the opposite direction.”

That plan was a last-minute addition to the state’s energy budget, which lawmakers in the Democratic-controlled Legislature reluctantly passed. Backers say it’s necessary to avoid the rolling blackouts like the state experienced during a heat wave in 2020. Critics see a muddled strategy on energy, and not what they expected from a nationally ambitious governor who has made climate action a centerpiece of his agenda.

The legislation, which some Democrats labeled as “lousy” and “crappy,” reflects the reality of climate change. Heat waves are already straining power capacity, and the transition to cleaner energy isn’t coming fast enough to meet immediate needs in the nation’s most populous state.

Officials have warned that outages would be possible this summer, as the grid faces heat wave tests again, with as many as 3.75 million California homes losing power in a worst-case scenario of a West-wide heat wave and insufficient electrical supplies, particularly in the evenings.

It’s also an acknowledgment of the political reality that blackout politics are hazardous to elected officials, even in a state dominated by one party.

Newsom emphasized that the money to prop up the power grid, part of a larger $4.3 billion energy spending package, is meant as a stop-gap measure. The bill allows the Department of Water Resources to spend $2.2 billion on “new emergency and temporary generators, new storage systems, clean generation projects, and funding on extension of existing generation operations, if any occur,” the governor said in a statement after signing the bill.

“Action is needed now to maintain reliable energy service as the State accelerates the transition to clean energy,” Newsom said.

Following the signing, the governor called for the state California Air Resources Board to add a set of ambitious goals to its 2022 Scoping Plan, which lays out California’s path for reducing carbon emissions.

Among Newsom’s requested changes is a move away from fossil fuels, asking state agencies to prepare for an energy transition that avoids the need for new natural gas plants.

Alex Stack, a spokesman for the governor, said in a statement that California has been a global leader in reducing pollution and exporting energy policies across Western states, and pointed to Newsom’s recent letter to the Air Resources Board as well as one sent to President Joe Biden outlining how states can work with the federal government to combat climate change.

“California took action to streamline permitting for clean energy projects to accelerate the build out of clean energy that is needed to meet our climate goals and help maintain reliability in the face of extreme heat, wildfires, and drought,” Stack said.

But the prospect of using state money on fossil fuel power, even in the short term, has raised ire among the state’s many environmental advocacy groups, and raised questions about whether California will be able to achieve its goals.

“What is so frustrating about an energy bill like this is that we are at crunch time to meet these goals,” said Mary Creasman, CEO of California Environmental Voters. “And we’re investing a scale of funding into things that exacerbate those goals.”

With climate change-induced drought and high temperatures continuing to ravage the West, California anticipates the demand on the grid will only continue to grow. Despite more than a decade of bold posturing and efforts to transition to solar, wind and hydropower, the state worries it doesn’t have enough renewable energy sources on hand to keep the power on in an emergency right now, amid a looming shortage that will test reliability.

The specter of power outages poses a hazard to Newsom, and Democrats in general, especially ahead of November. While the governor is widely expected to sail to reelection, rolling blackouts are a serious political liability — in 2003, they were the catalyst for recalling Democratic Gov. Gray Davis. A lack of power isn’t just about people sweating in the dark, said Steven Maviglio, a longtime Democratic consultant who served as communications director for Davis, it can affect businesses, travel and have an outsized impact on the economy.

It behooves any state official to keep the power on, but, unlike Davis, Newsom is under serious pressure to make sure the state also adheres to its climate goals.

“Gavin Newsom’s brand is based on climate change and clean air, so it’s a little more difficult for him to say ‘well that’s not as important as keeping the power on,’” Maviglio said.

The same bill effectively ends local government control over those projects, for the time being. It hopes to speed up the state’s production of renewable energy sources by giving exclusive authority over the siting of those projects to a single state agency for the next seven years.

Environmental advocates say the state is now scrambling to address an issue they’ve long known was coming. In 2010, California officials set a schedule to retire a number of coastal gas plants that rely on what’s known as once-through cooling systems, which are damaging to the environment, especially marine life, even as regulators weigh more power plants to maintain reliability today. Many of those plants have been retired since 2010, but others have received extensions.

The remaining plants have various deadlines for when they must cease operations, with the soonest being the end of 2023.

Also at issue is the embattled Diablo Canyon nuclear power plant, California’s largest electricity source. The Pacific Gas & Electric-owned plant is scheduled to close in 2025, but the strain on the grid has officials considering the possibility of seeking an extension. Newsom said earlier this spring he would be open to extending the life of the plant. Doing so would also require federal approval.

The International Brotherhood of Electrical Workers 1245, a labor union, sees the energy package as a way to preserve Diablo Canyon, and jobs at the plant.

“The value to 1245 PG&E members at Diablo Canyon is clear — funding to keep the plant open,” the union said of the bill.

Assemblymember Al Muratsuchi (D-Los Angeles) criticized the bill as “crappy” when it came to the floor in late June, describing it as “a rushed, unvetted and fossil-fuel-heavy response” to the state’s need to bolster the grid.

“The state has had over 12 years to procure and bring online renewable energy generation to replace these once through cooling gas power plants,” Muratsuchi said. “Yet, the state has reneged on its promise to shut down these plants, not once, but twice already.”

Not all details of the state’s energy budget are final. Lawmakers still have $3.8 billion to allocate when they return on Aug. 1 for the final stretch of the year.

Creasman, at California Environmental Voters, said she wants lawmakers to set specific guidelines for how and where it will spend the $2.2 billion when they return in August to dole out the remaining money in the budget. Newsom and legislators also need to ensure that this is the last time California has to spend money on fossil fuel, she said.

“Californians deserve to see what the plan is to make sure we’re not in this position again of having to choose between making climate impacts worse or keeping our lights on,” Creasman said. “That’s a false choice.”

Africa's Electricity Unlikely To Go Green This Decade

Africa 2030 Energy Mix Forecast finds electricity generation doubling, with fossil fuels dominant, non-hydro renewables under 10%, hydro vulnerable to droughts, and machine-learning analysis of planned power plants shaping climate and investment decisions.

 

Key Points

An analysis predicting Africa's 2030 power mix, with fossil fuels dominant, limited renewables growth, and hydro risks.

✅ ML model assesses 2,500 planned plants' commissioning odds

✅ Fossil fuels ~66% of generation; non-hydro RE <10% by 2030

✅ Policy shifts and finance reallocation to scale solar and wind

 

New research today from the University of Oxford predicts that total electricity generation across the African continent will double by 2030, with fossil fuels continuing to dominate the energy mix posing potential risk to global climate change commitments.

The study, published in Nature Energy, uses a state-of-the art machine-learning technique to analyse the pipeline of more than 2,500 currently-planned power plants and their chances of being successfully commissioned. It shows the share of non-hydro renewables in African electricity generation is likely to remain below 10% in 2030, although this varies by region.

'Africa's electricity demand is set to increase significantly as the continent strives to industrialise and improve the wellbeing of its people, which offers an opportunity to power this economic development and expand universal electricity access through renewables' says Galina Alova, study lead author and researcher at the Oxford Smith School of Enterprise and the Environment.

'There is a prominent narrative in the energy planning community that the continent will be able to take advantage of its vast renewable energy resources and rapidly decreasing clean technology prices to leapfrog to renewables by 2030 but our analysis shows that overall it is not currently positioned to do so.'

The study predicts that in 2030, fossil fuels will account for two-thirds of all generated electricity across Africa. While an additional 18% of generation is set to come from hydro-energy projects across Africa. These have their own challenges, such as being vulnerable to an increasing number of droughts caused by climate change.

The research also highlights regional differences in the pace of the transition to renewables across Sub-Saharan Africa, with southern Africa leading the way. South Africa alone is forecast to add almost 40% of Africa's total predicted new solar capacity by 2030.

'Namibia is committed to generate 70% of its electricity needs from renewable sources, including all the major alternative sources such as hydropower, wind and solar generation, by 2030, as specified in the National Energy Policy and in Intended Nationally Determined Contributions under Paris Climate Change Accord,' says Calle Schlettwein, Namibia Minister of Water (former Minister of Finance and Minister of Industrialisation). 'We welcome this study and believe that it will support the refinement of strategies for increasing generation capacity from renewable sources in Africa and facilitate both successful and more effective public and private sector investments in the renewable energy sector.'

Minister Schlettwein adds: 'The more data-driven and advanced analytics-based research is available for understanding the risks associated with power generation projects, the better. Some of the risks that could be useful to explore in the future are the uncertainties in hydrological conditions and wind regimes linked to climate change, and economic downturns such as that caused by the COVID-19 pandemic.'

The study further suggests that a decisive move towards renewable energy in Africa would require a significant shock to the current system. This includes large-scale cancellation of fossil fuel plants currently being planned. In addition, the study identifies ways in which planned renewable energy projects can be designed to improve their success chances for example, smaller size, fitting ownership structure, and availability of development finance for projects.

'The development community and African decision makers need to act quickly if the continent wants to avoid being locked into a carbon-intense energy future' says Philipp Trotter, study author and researcher at the Smith School. 'Immediate re-directions of development finance from fossil fuels to renewables are an important lever to increase experience with solar and wind energy projects across the continent in the short term, creating critical learning curve effects.'

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.
