Ontario Making it Easier to Build Electric Vehicle Charging Stations

Microgrid solar outage algorithms optimize renewable energy during blackouts using grid-forming inverters, islanding control, demand forecasting, and energy storage from batteries and EVs, improving reliability by up to 35% for resilient power sharing.

Key Points

Algorithms that island homes, forecast demand, and prioritize critical loads using storage and grid-forming inverters.

✅ Disconnects inverters to form resilient neighborhood microgrids

✅ Forecasts solar, wind, and demand; allocates energy fairly

✅ Uses EVs and batteries; boosts reliability by up to 35%

Some people who have solar panels on their roof are under the impression that they can use them to power their home in the case of an outage, but that simply is not the case. Homes do remain connected to the grid during outages, as U.S. power outage risks grow, but the devices tasked with managing solar panels are normally turned off due to safety concerns. This permanent grid connection essentially prevents homeowners from drawing on the power that their own renewable energy resources generate.

This could be about to change, however, thanks to the efforts of a team of University of California San Diego engineers who have come up with algorithms that would enable homes to share and use their power in outages by disconnecting solar inverters from the grid. Their algorithms work with the existing technology and would have the added benefit of boosting the system’s reliability by as much as 35 percent.

The genius of their work lies in the ability of the algorithm to prioritize the distribution of power from the renewable resources in outages. Their equation considers forecasts for wind and solar power generation to address clean energy intermittency challenges and the available energy storage, including batteries and electric vehicles. It combines this information with the projected energy usage of residents and the amount of energy the homes are able to produce. It can be programmed to prioritize in several different ways, the most vital of which is by favoring those who need power urgently, such as those using life support equipment. It could also prioritize those who are willing to pay extra or reward those who typically generate an energy surplus during normal operations.

Learning lessons from past outages

Lead author Abdulelah H. Habib said the engineers were inspired to find a way to use the renewable power in outages by the events of Hurricane Sandy. This storm affected more than eight million people on the nation’s East Coast, some of whom were left without power for as long as two weeks.

According to the researchers, most customers prefer sharing community-scale storage systems over having systems in each home because of the lower costs. One of the paper’s senior authors, Raymond de Callafon, said that homes that are connected together are not only more resilient in power outages but they also happen to be more resilient to price fluctuations.

Each home needs to be equipped with special circuit breakers that can be remotely controlled, while utilities would need to install some communications methods so the power systems within a particular residential cluster can communicate amongst themselves. They also need a “grid forming inverter” to help them connect to one another and manage excess solar on networks safely.

One stumbling block that will have to be overcome is the current regulations. Most states do not allow individual homeowners to sell power to other homeowners, so there would have to be some adjustments to make this a reality.

Solar power growing in popularity

Solar power’s popularity is currently on the rise, and reductions in cost as the technology improves are only expected to drive this growth even further. REC CEO Steve O’Neil told CNBC that the installation rates of solar double every two years, a trend that informs residential solar economics for homeowners even though just two percent of the planet’s electricity comes from converting sunlight to energy. This means there is plenty of room for expansion. The world’s current solar capacity is 305 gigawatts, compared to just 50 gigawatts in 2010.

In addition, he pointed out that the price of solar energy has dropped by 70 percent since the year 2010 and continues to fall; it costs around eight cents per kilowatt hour at the moment. Another factor that could boost adoption is storage improvements, driven by affordable solar batteries that expand capacity, which will allow solar energy to be used even on overcast days.

UK Renewable Grid Connection Delays threaten the 2035 zero-carbon electricity target as National Grid queues stall wind and solar projects, investors, and infrastructure, slowing clean energy deployment, curtailing capacity build-out, and risking net-zero progress.

Key Points

Prolonged National Grid queues delaying wind and solar connections, jeopardizing the UK's 2035 clean power target.

✅ Up to 15-year waits for grid connections

✅ Over £200bn projects stuck in the queue

✅ Threatens zero-carbon electricity by 2035

The UK currently has a 2035 target for 100% of its electricity to be produced without carbon emissions, while Ireland's green electricity progress offers a nearby benchmark within the next four years.

But meeting the target will require a big increase in the number of renewable projects across the country. It is estimated as much as five times more solar and four times as much wind is needed, with growth in UK offshore wind expected to play a key role here.

The government and private investors have spent £198bn on renewable power infrastructure since 2010, alongside European wind investments recorded last year. But now energy companies are warning that significant delays to connect their green energy projects to the system will threaten their ability to bring more green power online.

A new wind farm or solar site can only start supplying energy to people's homes once it has been plugged into the grid.

Energy companies like Octopus Energy, one of Europe's largest investors in renewable energy, say they have been told by National Grid that they need to wait up to 15 years for some connections, even as a new 10 GW contract aims to speed UK grid additions - far beyond the government's 2035 target.

'Longest grid queues in Europe'
There are currently more than £200bn worth of projects sitting in the connections queue, the BBC has calculated.

Around 40% of them face a connection wait of at least a year, according to National Grid's own figures. That represents delayed investments worth tens of billions of pounds, reflecting stalled grid spending that slows renewable rollouts.

"We currently have one of the longest grid queues in Europe," according to Zoisa North-Bond, chief executive of Octopus Energy Generation.

The problem is so many new renewable projects are applying for connections, the grid cannot keep up with required network expansion such as new pylons in Scotland being discussed nationwide.

The system was built when just a few fossil fuel power plants were requesting a connection each year, but now there are 1,100 projects in the queue, a challenge mirrored by U.S. grid hurdles in moving toward 100% renewables today.

EV Adoption Limits highlight that electric vehicles alone cannot meet emissions targets; life cycle assessment, carbon budgets, clean grids, public transit, and battery materials constraints demand broader decarbonization strategies, city redesign, and active travel.

Key Points

EV Adoption Limits show EVs alone cannot hit climate targets; modal shift, clean grids, and travel demand are essential.

✅ 350M EVs by 2050 still miss 2 C goals without major mode shift

✅ Grid demand rises 41%, requiring clean power and smart charging

✅ Battery materials constraints need recycling, supply diversification

Today there are more than seven million electric vehicles (EVs) in operation around the world, compared with only about 20,000 a decade ago. It’s a massive change – but according to a group of researchers at the University of Toronto’s Faculty of Applied Science & Engineering, it won’t be nearly enough to address the global climate crisis. 

“A lot of people think that a large-scale shift to EVs will mostly solve our climate problems in the passenger vehicle sector,” says Alexandre Milovanoff, a PhD student and lead author of a new paper published in Nature Climate Change. 

“I think a better way to look at it is this: EVs are necessary, but on their own, they are not sufficient.” 

Around the world, many governments are already going all-in on EVs. In Norway, for example, where EVs already account for half of new vehicle sales, the government has said it plans to eliminate sales of new internal combustion vehicles by 2025. The Netherlands aims to follow suit by 2030, with France and Canada's EV goals aiming to follow by 2040. Just last week, California announced plans to ban sales of new internal combustion vehicles by 2035.

Milovanoff and his supervisors in the department of civil and mineral engineering – Assistant Professor Daniel Posen and Professor Heather MacLean – are experts in life cycle assessment, which involves modelling the impacts of technological changes across a range of environmental factors. 

They decided to run a detailed analysis of what a large-scale shift to EVs would mean in terms of emissions and related impacts. As a test market, they chose the United States, which is second only to China in terms of passenger vehicle sales. 

“We picked the U.S. because they have large, heavy vehicles, as well as high vehicle ownership per capita and high rate of travel per capita,” says Milovanoff. “There is also lots of high-quality data available, so we felt it would give us the clearest answers.” 

The team built computer models to estimate how many electric vehicles would be needed to keep the increase in global average temperatures to less than 2 C above pre-industrial levels by the year 2100, a target often cited by climate researchers. 

“We came up with a novel method to convert this target into a carbon budget for U.S. passenger vehicles, and then determined how many EVs would be needed to stay within that budget,” says Posen. “It turns out to be a lot.” 

Based on the scenarios modelled by the team, the U.S. would need to have about 350 million EVs on the road by 2050 in order to meet the target emissions reductions. That works out to about 90 per cent of the total vehicles estimated to be in operation at that time. 

“To put that in perspective, right now the total proportion of EVs on the road in the U.S. is about 0.3 per cent,” says Milovanoff. 

“It’s true that sales are growing fast, but even the most optimistic projections of an electric-car revolution suggest that by 2050, the U.S. fleet will only be at about 50 per cent EVs.” 

The team says that, in addition to the barriers of consumer preferences for EV deployment, there are technological barriers such as the strain that EVs would place on the country’s electricity infrastructure, though proper grid management can ease integration. 

According to the paper, a fleet of 350 million EVs would increase annual electricity demand by 1,730 terawatt hours, or about 41 per cent of current levels. This would require massive investment in infrastructure and new power plants, some of which would almost certainly run on fossil fuels in some regions. 

The shift could also impact what’s known as the demand curve – the way that demand for electricity rises and falls at different times of day – which would make managing the national electrical grid more complex, though vehicle-to-grid strategies could help smooth peaks. Finally, there are technical challenges stemming from the supply of critical materials for batteries, including lithium, cobalt and manganese. 

The team concludes that getting to 90 per cent EV ownership by 2050 is an unrealistic scenario. Instead, what they recommend is a mix of policies, rather than relying solely on a 2035 EV sales mandate as a singular lever, including many designed to shift people out of personal passenger vehicles in favour of other modes of transportation. 

These could include massive investment in public transit – subways, commuter trains, buses – as well as the redesign of cities to allow for more trips to be taken via active modes such as bicycles or on foot. They could also include strategies such as telecommuting, a shift already spotlighted by the COVID-19 pandemic. 

“EVs really do reduce emissions, which are linked to fewer asthma-related ER visits in local studies, but they don’t get us out of having to do the things we already know we need to do,” says MacLean. “We need to rethink our behaviours, the design of our cities, and even aspects of our culture. Everybody has to take responsibility for this.” 

The research received support from the Hatch Graduate Scholarship for Sustainable Energy Research and the Natural Sciences and Engineering Research Council of Canada.

U.S. Renewable Energy Forecast 2024 will see wind and solar power surpass one-fourth of electricity generation, EIA projects, as coal declines, natural gas dips, and clean energy capacity, grid integration, and policy incentives expand.

Key Points

EIA outlook: renewables at 26% of U.S. power in 2024, led by wind and solar as coal declines and gas share dips.

✅ Wind and solar hit 18% combined, surpassing coal's 17%.

✅ Natural gas dips to 37% as demand rebounds modestly.

✅ Coal plant closures accelerate amid costs, emissions, and age.

Renewable energy is poised to reach a milestone, after a record 28% in April this year, as a new government report projects that wind, solar and other renewable sources will exceed one-fourth of the country’s electricity generation for the first time, in 2024.

This is one of the many takeaways from the federal government’s Short Term Energy Outlook, a monthly report whose new edition is the first to include a forecast for 2024. The report’s authors in the Energy Information Administration are expecting renewables to increase in market share, while natural gas and coal would both decrease.

From 2023 to 2024, renewables would rise from 24 percent to 26 percent of U.S. electricity generation; coal’s share would drop from 18 percent to 17 percent; gas would remain the leader but drop from 38 percent to 37 percent; and nuclear would be unchanged at 19 percent.

It was a big deal in 2020 when generation from renewables passed coal for the first time in 130 years over a full year. Coal made a comeback in 2021 and then retreated again in 2022 as renewables surpassed coal in generation. The ups and downs were largely the result of fluctuations in electricity demand during and then after the Covid-19 pandemic.

The new report indicates that coal doesn’t have another comeback in the works. This fuel, which was the country’s leading electricity source less than a decade ago, is declining as many coal-fired power plants are old and economically uncompetitive. Coal plants continue to close, and developers aren’t building new ones because of concerns about high costs and emissions, a trend underscored when renewables became the second-most prevalent source in 2020 across the U.S.

The growth in renewable energy is coming from wind and solar power, with wind responsible for about one-third of the growth and solar accounting for two-thirds, the report says, and combined output from wind and solar has already exceeded nuclear for the first time in the U.S. Other renewable sources, like hydropower and biomass, would be flat.

In fact, the growth of wind and solar is projected to be so swift that the combination of just those two sources would be 18 percent of the U.S. total by 2024, which would surpass coal’s 17 percent.

A key variable is overall electricity consumption. EIA is projecting that this will fall 1 percent in 2023 compared to 2022, due a mild summer. Then, consumption will increase 1 percent in 2024.

If demand was rising more, then natural gas power would likely gain market share because of gas power plants’ ability to vary their output as needed to respond to changes in demand.

I asked Eric Gimon, a senior fellow at the think tank Energy Innovation, what he thinks of these latest numbers.

He said wind and solar have gotten so big that it almost makes sense to track them as their own categories as opposed to lumping them into the larger category of renewables. He expects that the government will do this sometime soon.

Also, he thinks the projected increases for wind and solar, while substantial, are still smaller than those resources are likely to grow.

“My experience over the last 10 years is that the EIA tends to have flattish forecasts,” he said, meaning the federal office has underestimated the actual growth.

Some energy analysts have criticized EIA for being slow to recognize the growth of renewables. But much of the criticism is about the Annual Energy Outlook, which has numbers going out to mid-century, even as the U.S. is moving toward 30% from wind and solar by the end of the decade. The Short Term Energy Outlook, with numbers going one year into the future, has been more reliable.

Gimon said EIA is “kind of like your conservative uncle” in its forecasts, so it’s notable that the office expects to see a significant uptick in wind and solar.

Even so, he thinks the latest Short Term Energy Outlook should be read as the lower end of the range of potential increase for wind and solar.

For him to be right, the wind and solar industries will need to figure out solutions to the challenges they’ve been having in obtaining parts; they will need to make progress in dealing with local opposition to many projects and in having enough interstate power lines to deliver the electricity. And, new policies like the Inflation Reduction Act will need to have their desired effect of encouraging projects through the use of tax incentives.

It’s not much of a stretch to imagine that clean energy industries will make some progress on all of those fronts.

Bioo Soil-Generated Electricity turns biological batteries and photosynthesis into renewable energy, powering IoT sensors for smart farming and lighting, using microbe-powered soil electrochemistry to cut battery waste, reduce costs, and scale sustainable agritech infrastructure.

Key Points

Bioo Soil-Generated Electricity powers IoT sensors and lighting using soil microbes, delivering clean renewable energy.

✅ Microbe-driven soil batteries replace disposable chemical cells

✅ Powers IoT agritech sensors for moisture, pH, and temperature

✅ Cuts maintenance and costs while enabling sustainable farming

SCENES shines a spotlight on youth around the world that are breaking down barriers and creating change. The character-driven short films will inspire and amaze, as these young change-makers tell their remarkable stories.

Pablo Vidarte is a born inventor. At the age of eight, he was programming video games. By 16, he was challenging NASA and competing with the Spanish army to enhance the efficiency of external combustion engines. "I wanted to perfect a system that NASA did in 2002 oriented to powering cars. I was able to increase that efficiency by 60 per cent, which was pretty cool," Pablo explained. Aged 18, he created his first company specialising in artificial intelligence. A year later, he founded Bioo, a revolutionary startup that generates electricity from plants' photosynthesis.

"Imagine, being in the middle of a park or a street and being able to touch a plant and turn on the lights of that specific area," Pablo told Scenes. "Imagine storing the memories of humanity itself in nature. Imagine storing voice messages in a library that is an open field where you can go and touch the plants and communicate and interact with them. That's what we do at Bioo," he added.

The creation of Bioo, however, was not a walk in the park. Pablo relied on nanotechnology engineers and biologists volunteering their time to turn his idea of biological batteries, inspired by biological design, into a reality. It took a year for a prototype to be created and an investor to come on board. Today, Bioo is turning plants into biological switches, generating renewable energy from nature, and transforming the environment.

"We realised that we were basically killing the planet, and then we invented things like solar panels and solutions like peer-to-peer energy that we're able to prevent things from getting worse, but the next step is to be able to reverse the whole equation to revive that planet that we're starting to lose," the 25-year-old explained.

Batteries creating electricity from soil
Bioo has designed biological batteries that generate electricity from the energy released when organic soil decomposes. Like traditional batteries, they have an anode and a cathode, but instead of using materials like lithium to power them, organic matter is used as fuel. When microorganisms break down the organic soil, electrons are released. These electrons are then transported from the anode to the cathode, and a current of electricity is created. The batteries come in the shape of a rectangular box and can be dug into any fertile soil. They produce up to 200Wh a year per square metre, and just as some tidal projects use underwater kites to harvest energy, these systems tap natural processes.

Bioo's batteries are limited to low-power applications, but they have grown in popularity and are set to transform the agriculture industry.

Cost savings for farmers
Farmers can monitor their crops using a large network of sensors. The sensors allow them to analyse growing conditions, such as soil moisture, PH levels and air temperature. Almost 90 per cent of the power used to run the sensors come from chemical batteries, which deplete, underscoring the renewable energy storage problem that new solutions target.

"The huge issue is that chemical batteries need to be replaced every single year. But the problem is that you literally need an army of people replacing batteries and recalibrating them," Pablo explains. "What we do, it's literally a solution that is hidden, and that's nourishing from the soil itself and has the same cost as using chemical batteries. So the investment is basically returned in the first year," Pablo added.

Bioo has partnered with Bayer, a leading agricultural producer, to trial their soil-powered sensors on 50 million hectares of agricultural land. If successful, the corporation could save €1.5 billion each year. Making it a game-changer for farmers around the world.

A BioTech World
In addition to agriculture, Bioo's batteries are now being installed in shopping centres, offices and hospitals to generate clean power for lighting, while other companies are using ocean and river power to diversify clean generation portfolios.

Pablo's goal is to create a more environmentally efficient world, so shares his technology with international tech companies as green hydrogen projects scale globally. "I wanted to do something that could really mean a change for our world. Our ambition right now is to create a biotech world, a world that is totally interconnected with nature," he said.

As Bioo continues to develop its technology, Pablo believes that soil-generated electricity will become a leader in the global energy market, aligning with progress toward cheap, abundant electricity becoming a reality worldwide.

Tesla Q2 2020 earnings highlight resilient electric vehicles as production and deliveries outpace legacy automakers, while Gigafactory Austin advances, solar installations slump, and energy storage, Megapack, and free cash flow expand despite COVID-19 disruptions.

Key Points

Tesla posted a fourth consecutive profit, strong cash, EV resilience, solar slump, and rising energy storage.

✅ Fourth straight profit and $418M free cash flow

✅ EV output and deliveries fell just 5% year over year

✅ Solar hit record low; storage rose 61% to 419 MWh

Tesla survived the throes of the coronavirus pandemic relatively unscathed, chalking up its fourth sequential quarterly profit for the first time on Wednesday.

On the energy front, however, things were much more complicated: Tesla reported its worst-ever quarter for solar installations but huge growth in its battery business, amid expectations for cheaper, more powerful batteries expected in coming years. CEO Elon Musk nevertheless predicted the energy business will one day rival its car division in scale.

But today, Tesla's bottom line is all about electric vehicles, and the temporary halt of activity at Tesla's Fremont factory due to local health orders didn’t put much of a dent in vehicle production and delivery. Both figures declined 5 percent compared to the same quarter in 2019. In contrast, Q2 vehicle sales at legacy carmakers Ford, GM and Fiat Chrysler declined by one-third or more year-over-year, even as the U.S. EV market share dipped in early 2024 for context.

The costs of factory closures and a $101 million CEO award milestone for Elon Musk didn’t stop Tesla from achieving $418 million in free cash flow, a major improvement over the prior quarter. Cash and cash equivalents grew by $535 million to $8.6 billion during the quarter.

Musk praised his employees for “exceptional execution.” 

“There were so many challenges, too numerous to name, but they got it done,” he said on an investor call Wednesday.

Musk also confirmed that Tesla will build a new Gigafactory in Austin, Texas, five minutes from the airport. The 2,000-acre campus will abut the Colorado River and is “basically going to be an ecological paradise,” he said. The new Texas factory will build the Cybertruck, Semi, Model 3 and Model Y for the Eastern half of North America. Fremont, California will produce the S and X, and make Model 3 and Model Y for the West, in a state where EVs exceed 20% of sales according to recent data.

Return of the Tesla solar slump

This was the first entire quarter affected by the coronavirus response, which threw the rooftop solar industry into turmoil by cutting off in-person sales. Other installers scrambled to shift to digital-first sales strategies, but Tesla had already done so months before lockdowns were imposed.

Q2, then, offers a test case on whether Tesla’s pivot to passive online sales made it better able to deal with stay-at-home orders than its peers. The other publicly traded solar installers have not yet reported their Q2 performance, but Tesla delivered its worst-ever quarterly solar figures: Installations totaled just 27 megawatts. That’s a 7 percent decline from Q2 2019, its previous worst quarter ever for solar.

Musk did not address that weak performance in his remarks to investors, opting instead to highlight the company’s late-June decision to offer the cheapest solar pricing in the country. “We’re the company to go to,” he said of rooftop solar. “It’s only going to get better later this year.”

But the sales slump indicates Tesla’s online sales model could not withstand a historically tough season for residential solar.

"Every single residential installer in the country is going to have a bad Q2 because of the initial impacts of COVID on the market," said Austin Perea, senior solar analyst at Wood Mackenzie. "It's hard to disaggregate the impacts of COVID from their own individual strategies."

Tesla's 23 percent decline in quarter-over-quarter solar installations was not as bad as the expected Q2 decline across the rooftop solar industry, Perea added.

On the vehicle side, Tesla’s sales declined less than did those of major automakers. It’s possible that the same pattern will hold for solar; a less severe drop than those seen by Sunrun or Vivint could be claimed as a victory of sorts. But this quarter made clear that Q2 2019 was not the bottom for Tesla’s solar operation, which once led the residential market as SolarCity but significantly diminished since Tesla acquired it in 2016.

Tesla currently stands in third place for residential solar installers. But No. 1 installer Sunrun said this month that it will acquire No. 2 installer Vivint Solar, making Tesla the second-largest installer by default. That major consolidation in the rooftop solar market went unremarked upon in Tesla's investor call.

Solar and energy storage revenue currently equate to just 7 percent of the company's automotive revenue. But Musk reiterated his prediction that this won’t always be the case. “Long term, Tesla Energy will be roughly the same size as Tesla Automotive,” he said on Wednesday's call.

The grid storage business offered more reason for optimism: Capacity deployed grew 61 percent from the first quarter, rising to 419 megawatt-hours. The prepackaged, large-format Megapack product turned its first profit that quarter.

"Difficult to predict" performance in the second half of 2020
Tesla withdrew its financial guidance last quarter in light of the upheaval across the global economy. It refrained from setting new guidance now.

“Although we have successfully ramped vehicle production back to prior levels, it remains difficult to predict whether there will be further operational interruptions or how global consumer sentiment will evolve, given risks to the EV boom noted by analysts, in the second half of 2020,” the earnings report notes.

The company asserted it will still deliver 500,000 vehicles this year regardless of externalities, a goal that aligns with broader EV sales momentum in 2024 trends. It already has sufficient production capacity installed to reach that, Tesla said. But with 179,387 cars delivered so far, Tesla faces an uphill climb to ship more cars in the second half.

Wall Street maintained its buoyant confidence in Tesla's share price, despite rising competition in China noted by rivals. It closed at $1,592 before the earnings announcement, rising to $1,661 in after-hours trading.
