Electric vehicles can now power your home for three days

O2 Tidal Turbine delivers tidal energy in Orkney, Scotland, supplying grid-connected renewable power via EMEC and enabling green hydrogen production, providing clean electricity with predictable generation from strong coastal currents.

Key Points

A 2 MW, grid-connected tidal device in Orkney that delivers clean power and enables EMEC green hydrogen production.

✅ 2 MW capacity; powers ~2,000 UK homes via EMEC grid

✅ Predictable renewable output from strong coastal currents

✅ Enables onshore electrolyzer to produce green hydrogen

“The world’s most powerful” tidal turbine has been hooked up to the onshore electricity grid in Orkney, a northerly archipelago in Scotland, and is ready to provide homes with clean, green electricity, even as a major UK offshore windfarm begins supplying power this week.

The tidal turbine, known as the O2, was developed by Scottish engineering firm Orbital Marine Power. On July 28, they announced O2 “commenced grid connected power generation” at the European Marine Energy Centre (EMEC) in Orkney, meaning it's all set up and providing energy to the local power grid, similar to another Scottish tidal project that recently powered nearly 4,000 homes.

The 74-meter-long (242-foot) turbine is said to be “the world’s most powerful” tidal turbine. It will lay in the waters off Orkney for the next 15 years with the capacity to meet the annual electricity demand of around 2,000 UK homes. The 2MW turbine is also set to power the EMEC’s land-based electrolyzer that will generate green hydrogen (hydrogen made without fossil fuels) that can also be used as a clean energy source, in a UK energy system that recently set a wind generation record for output.

“Our vision is that this project is the trigger to the harnessing of tidal stream resources around the world and, alongside investment in UK offshore wind, to play a role in tackling climate change whilst creating a new, low-carbon industrial sector,” Orbital CEO, Andrew Scott, said in a press release.

Tidal energy is harnessed by converting energy from the natural rise and fall of ocean tides and currents. The O2 turbine consists of two submerged blades with a 20-meter (65-foot) diameter attached to a turbine that will move with the shifting currents of Orkney’s coast to generate electricity. Electricity is then transferred from the turbine along the seabed via cables towards the local onshore electricity network, a setup also being used by a Nova Scotia tidal project to supply the grid today.

This method of harnessing energy is not just desirable because it doesn't release carbon emissions, but it’s more predictable than other renewable energy sources, such as solar or Scotland's wind farms that can be influenced by weather conditions. Tidal energy production is still in its infancy and there are relatively few large-scale tidal power plants in the world, but many argue that some parts of the world could potentially draw huge benefits from this innovative form of hydropower, especially coastal regions with strong currents such as the northern stretches of the UK and the Bay of Fundy in Atlantic Canada.

The largest tidal power operation in the world is the Sihwa Lake project on the west coast of South Korea, which harnesses enough power to support the domestic needs of a city with a population of 500,000 people. However, once fully operational, the MeyGen tidal power project in northern Scotland hopes to snatch its title.

BC Hydro Vehicle-to-Grid Pilot enables EVs to deliver V2G power, using bidirectional charging to provide grid services, clean energy resilience, and emergency power for microgrids, critical infrastructure, and storm response.

Key Points

BC Hydro's V2G pilot uses parked EVs as mobile batteries, supplying bidirectional power to the grid for resilience.

✅ Medium- and heavy-duty EV integration via 60 kW charger

✅ Supports critical infrastructure and storm response

✅ Cleaner, faster alternative to diesel generators

BC Hydro has unveiled an innovative pilot project designed to enable electric vehicles (EVs) to contribute electricity back to the power grid, with some owners able to sell electricity back to the grid through managed programs, effectively transforming these vehicles into mobile energy storage units that function as capacity on wheels for the electricity system.

The utility company recently announced the successful trial of the vehicle-to-grid program, allowing for the transfer of electricity from the batteries of medium- and heavy-duty EVs back to the electrical grid. This surplus electricity can be utilized in various ways, including supporting emergency response efforts by energizing critical infrastructure and to power buildings during natural disasters or major storms. It offers a cleaner, faster, and more flexible alternative to conventional methods like the use of diesel generators.

BC Hydro's President and CEO, Chris O'Riley, highlighted the significance of this initiative, stating, "The average car is parked 95 per cent of the time, and with the evolution of technology solutions like vehicle-to-grid, stationary vehicles hold the potential to become mobile batteries, powered by clean and affordable electricity."

The successful test was conducted using a Lion Electric school bus provided by Lynch Bus Lines, which was connected to a 60-kilowatt charger, illustrating BC Hydro's rollout of faster electric vehicle charging across the province. BC Hydro pointed out that the typical bus battery holds 66 kilowatts of electricity, sufficient to power 24 single-family homes with electric heating for two hours. Therefore, if 1,000 of these buses were converted to electric power, they could collectively supply electricity to 24,000 homes for two hours.

This groundbreaking project is a collaborative effort between BC Hydro, Powertech, and Coast to Coast Experience, with funding support from the provincial government amid study findings that B.C. may need to double its power output to meet transport electrification.

While this pilot marks the first of its kind in Canada, similar technology has already been successfully implemented in Europe and the United States, including California's efforts to leverage EVs for grid stability that offer promising potential for enhancing the energy landscape and sustainability in the region.

Separately, Nova Scotia Power plans to pilot electric vehicle to grid integration in Atlantic Canada, underscoring growing national interest in V2G approaches.

California Gas Car Ban 2035 signals a shift to electric vehicles, raising grid reliability concerns, charging demand, and renewable energy challenges across solar, wind, and storage, amid rolling blackouts and carbon-free power mandates.

Key Points

An order ending new gasoline car sales by 2035 in California, accelerating EV adoption and pressuring the power grid.

✅ 25% EV fleet could add 232.5 GWh/day charging demand by 2040

✅ Solar and wind intermittency strains nighttime home charging

✅ Grid upgrades, storage, and load management become critical

On September 23, California Gov. Gavin Newsom issued an executive order that will ban the sale of gasoline-powered cars in the Golden State by 2035. Ignoring the hard lessons of this past summer, when California’s solar- and wind-reliant electric grid underwent rolling blackouts, Newsom now adds a huge new burden to the grid in the form of electric vehicle charging, underscoring the need for a much bigger grid to meet demand. If California officials follow through and enforce Newsom’s order, the result will be a green new car version of a train wreck.

In parallel, the state is moving on fleet transitions, allowing electric school buses only from 2035, which further adds to charging demand.

Let’s run some numbers. According to Statista, there are more than 15 million vehicles registered in California. Per the U.S. Department of Energy, there are only 256,000 electric vehicles registered in the state—just 1.7 percent of all vehicles, a share that will challenge state power grids as adoption grows.

Using the Tesla Model3 mid-range model as a baseline for an electric car, you’ll need to use about 62 kilowatt-hours (KWh) of power to charge a standard range Model 3 battery to full capacity. It will take about eight hours to fully charge it at home using the standard Tesla NEMA 14-50 charger, a routine that has prompted questions about whether EVs could crash the grid by households statewide.

Now, let’s assume that by 2040, five years after the mandate takes effect, also assuming no major increase in the number of total vehicles, California manages to increase the number of electric vehicles to 25 percent of the total vehicles in the state. If each vehicle needs an average of 62 kilowatt-hours for a full charge, then the total charging power required daily would be 3,750,000 x 62 KWh, which equals 232,500,000 KWh, or 232.5 gigawatt-hours (GWh) daily.

Utility-scale California solar electric generation according to the energy.ca.gov puts utility-scale solar generation at about 30,000 GWh per year currently. Divide that by 365 days and we get 80 GWh/day, predicted to double, to 160 GWh /day. Even if we add homeowner rooftop solar, and falling prices for solar and home batteries in the wake of blackouts, about half the utility-scale, at 40 GWh/day we come up to 200 GW/h per day, still 32 GWh short of the charging demand for a 25% electric car fleet in California. Even if rooftop solar doubles by 2040, we are at break-even, with 240GWh of production during the day.

Bottom-line, under the most optimistic best-case scenario, where solar operates at 100% of rated capacity (it seldom does), it would take every single bit of the 2040 utility-scale solar and rooftop capacity just to charge the cars during the day. That leaves nothing left for air conditioning, appliances, lighting, etc. It would all go to charging the cars, and that’s during the day when solar production peaks.

But there’s a much bigger problem. Even a grade-schooler can figure out that solar energy doesn’t work at night, when most electric vehicles will be charging at homes, even as some officials look to EVs for grid stability through vehicle-to-grid strategies. So, where does Newsom think all this extra electric power is going to come from?

The wind? Wind power lags even further behind solar power. According to energy.gov, as of 2019, California had installed just 5.9 gigawatts of wind power generating capacity. This is because you need large amounts of land for wind farms, and not every place is suitable for high-return wind power.

In 2040, to keep the lights on with 25 percent of all vehicles in California being electric, while maintaining the state mandate requiring all the state’s electricity to come from carbon-free resources by 2045, California would have to blanket the entire state with solar and wind farms. It’s an impossible scenario. And the problem of intermittent power and rolling blackouts would become much worse.

And it isn’t just me saying this. The U.S. Environmental Protection Agency (EPA) agrees. In a letter sent by EPA Administrator Andrew Wheeler to Gavin Newsom on September 28, Wheeler wrote:

“[It] begs the question of how you expect to run an electric car fleet that will come with significant increases in electricity demand, when you can’t even keep the lights on today.

“The truth is that if the state were driving 100 percent electric vehicles today, the state would be dealing with even worse power shortages than the ones that have already caused a series of otherwise preventable environmental and public health consequences.”

California’s green new car wreck looms large on the horizon. Worse, can you imagine electric car owners’ nightmares when California power companies shut off the power for safety reasons during fire season? Try evacuating in your electric car when it has a dead battery.

Gavin Newsom’s “no more gasoline cars sold by 2035” edict isn’t practical, sustainable, or sensible, much like the 2035 EV mandate in Canada has been criticized by some observers. But isn’t that what we’ve come to expect with any and all of these Green New Deal-lite schemes?

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.

Canadian Electric Bus Fleet leads North America as Toronto's TTC deploys 59 battery-electric, zero-emission buses, advancing public transit decarbonization with charging infrastructure, federal funding, lower maintenance, and lifecycle cost savings for a low-carbon urban future.

Key Points

Canada's leading battery-electric transit push, led by Toronto's TTC, scaling zero-emission buses and charging.

✅ Largest battery-electric bus fleet in North America

✅ TTC trials BYD, New Flyer, Proterra for range and reliability

✅ Charging infrastructure, funding, and specs drive 2040 zero-emissions

The largest battery-powered electric bus fleet in North America is Canadian. Toronto's transit system is now running 59 electric buses from three suppliers, and Edmonton's first electric bus is now on the road as well. And Canadian pioneers such as Toronto offer lessons for other transit systems aiming to transition to greener fleets for the low-carbon economy of the future.

Diesel buses are some of the noisier, more polluting vehicles on urban roads. Going electric could have big benefits, even though 18% of Canada's 2019 electricity from fossil fuels remains a factor.

Emissions reductions are the main reason the federal government aims to add 5,000 electric buses to Canada's transit and school fleets by the end of 2024. New funding announced this week as part of the government's fall fiscal update could also give programs to electrify transit systems a boost.

"You are seeing huge movement towards all-electric," said Bem Case, the Toronto Transit Commission's head of vehicle programs. "I think all of the transit agencies are starting to see what we're seeing ... the broader benefits."

While Vancouver has been running electric trolley buses (more than 200, in fact), many cities (including Vancouver) are now switching their diesel buses to battery-electric buses in Metro Vancouver that don't require overhead wires and can run on regular bus routes.

The TTC got approval from its board to buy its first 30 battery-electric buses in November 2017. Its plan is to have a zero-emissions fleet by 2040.

That's a crucial part of Toronto's plan to meet its 2050 greenhouse gas targets, which requires 100 per cent of vehicles to transition to low-carbon energy by then.

But Case said the transition can't happen overnight. 

Finding the right bus
For one thing, just finding the right bus isn't easy.

"There's no bus, by any manufacturer, that's been in service for the entire life of a bus, which is 12 years," Case said.

"And so really, until then, we don't have enough experience, nor does anyone else in the industry, have enough experience to commit to an all-electric fleet immediately."

In fact, Case said, there are only three manufacturers that make suitable long-range buses — the kind needed in a city the size of Toronto.

Having never bought electric buses before, the city had no specifications for what it needed in an electric bus, so it decided to try all three suppliers: Winnipeg-based New Flyer; BYD, which is headquartered in Shenzhen, China, but built the TTC buses at its Newmarket, Ont. facility; and California-based Proterra.

They all had their strengths and weaknesses, based on their backgrounds as a traditional non-electric bus manufacturer, a battery maker and a vehicle technology and design startup, respectively.

"Each bus type has its own potential challenges." Case said all three manufacturers are working to resolve any adoption challenges as quickly as possible.

But the biggest challenge of all, Case said, is getting the infrastructure in place. 

"There's no playbook, really, for implementing charging infrastructure," he said.

Each bus type needed their own chargers, in some cases using different types of current. Each type has been installed in a different garage in partnership with local utility Toronto Hydro.

Buying and installing them represented about $70 million, or about half the cost of acquiring Toronto's first 60 electric buses. The $140 million project was funded by the federal Public Transit Infrastructure Fund.

Case said it takes about three hours to charge a battery that has been fully depleted. To maximize use of the bus, it's typically put on a long route in the morning, covering 200 to 250 kilometres. Then it's partially charged and put on a shorter run in the late afternoon.

"That way we get as much mileage on the buses as we can."

Cost and reliability?
Besides the infrastructure cost of chargers, each electric bus can cost $200,000 to $500,000 more per bus than an average $750,000 diesel bus. 

Case acknowledges that is "significantly" more expensive, but it is offset by fuel savings over time, as electricity costs are cheaper. Because the electric buses have fewer parts than diesel buses, maintenance costs are also about 25 per cent lower and the buses are expected to be more reliable.

As with many new technologies, the cost of electric buses is also falling over time.

Case expects they will eventually get to the point where the total life-cycle cost of an electric and a diesel bus are comparable, and the electric bus may even save money in the long run.

As of this fall, all but one of the 60 new electric buses have been put into service. The last one is expected to hit the road in early December.

Summer testing showed that air conditioning the buses reduced the battery capacity by about 15 per cent. 

But the TTC needs to see how much of the battery capacity is consumed by heating in winter, at least when the temperature is above 5 C. Below that, a diesel-powered heater kicks in.

Once testing is complete, the TTC plans to develop specifications for its electric bus fleet and order 300 more in 2023, for delivery between 2023 and 2025.

Potential benefits
Even with some diesel heating, the TTC estimates electric buses reduce fuel usage by 70 to 80 per cent. If its whole fleet were switched to electric buses, it could save $50 million to $70 million in fuel a year and 150 tonnes of greenhouse gases per bus per year, or 340,000 tonnes for the entire fleet.

Other than greenhouse gases, electric buses also generate fewer emissions of other pollutants. They're also quieter, creating a more comfortable urban environment for pedestrians and cyclists.

But the benefits could potentially go far beyond the local city.

"If the public agencies start electrifying their fleet and their service is very demanding, I think they'll demonstrate to the broader transportation industry that it is possible," Case said.

"And that's where you'll get the real gains for the environment."

Alex Milovanoff, a postdoctoral researcher in the University of Toronto's department of civil engineering, did a U of T EV study that suggested electrified transit has a crucial role to play in the low-carbon economy of the future.

His calculations show that 90 per cent of U.S. passenger vehicles — 300 million — would need to be electric by 2050 to reach targets under the global Paris Agreement to fight climate change.

And that would put a huge strain on resources, including both the mining of metals, such as lithium and cobalt, that are used in electric vehicle batteries and the electrical grid itself.

A better solution, he showed, was combining the transition to electric vehicles with a reduction in the number of private vehicles, and higher usage of transit, cycling and walking.

"Then that becomes a feasible picture," he said.

What's needed to make the transition
But in order to make that happen, governments need to make investments and navigate the 2035 EV mandate debate on timelines, he added.

That includes subsidies for buying electric buses and building charging stations so transit agencies don't need to make fares too high. But it also includes more general improvements to the range and reliability of transit infrastructure.

"Electrifying the bus fleet is only efficient if we have a large public transit fleet and if we have many buses on the road and if people take them," Milovanoff said.

In its fall economic update on Monday, the federal government announced $150 million over three years to speed up the installation of zero-emission vehicle infrastructure.

Josipa Petrunic, CEO of the Canadian Urban Transit Research and Innovation Consortium, a non-profit organization focused on zero-carbon mobility and transportation, said that in the past, similar funding has paid for high-powered charging systems for transit systems in B.C. and Ontario. But that's only a small part of what's needed, she said.

"Infrastructure Canada needs to come to the table with the cash for the buses and the whole rest of the system."

She said funding is needed for:

Feasibility studies to figure out how many and what kinds of buses are needed for different routes in different transit systems.

Targets and incentives to motivate transit systems to make the switch.

Incentives to encourage Canadian procurement to build the industry in Canada.

Technology to collect and share data on the performance of electric vehicles so transit systems can make the best-possible decisions to meet the needs of their riders.

Petrunic said that a positive side-effect of electrifying transit systems is that the infrastructure can support, in addition to buses, electric trucks for moving freight.

"It's not a lot given that we have 15,000 buses out there in the transit fleet," she said.

"But we should be able to get a lot further ahead if we match the city commitments to zero emissions with federal and provincial funding for jobs creating zero-emissions technologies."

EV Carpocalypse signals potential mismatch between electric vehicle production and demand, as charging infrastructure, utility coordination, and plug-in hybrid strategies lag forecasts, while state mandates and market-share plays drive cautious, data-informed scaling.

Key Points

EV Carpocalypse describes overbuilt EV supply versus demand amid charging rollout, mandates, and risk-managed scaling.

✅ Forecasts vs actual EV demand may diverge in near term

✅ Charging infrastructure and utilities lag vehicle output

✅ Mandates and PHEVs cushion adoption while data guides scaling

According to Forbes contributor David Kiley, and Wards Automotive columnist John McElroy, there may be an impending “carpocalypse” of electric vehicles on the way. Sounds very damning and it’s certainly not the upbeat tone I’ve taken on nearly every piece of EV demand content I’ve authored but the author, Kiley does bring up some interesting points worth considering. EV Adoption is happening, and it’s certainly doing so at ever faster rates as the market nears an EV inflection point today. The infrastructure (charging stations, utility cooperation) is being built out more slowly than vehicle manufacturers are producing cars but, as the GM president on EV hurdles has noted, the issue seems to be just that, maybe even the short and medium term plans for EV manufacturing are too aggressive.

#google#

With new EV and plug-in hybrid vehicle sales representing a mere .6% of new car cales in the US, a sign that EV sales remain behind gas cars even as new models proliferate, car makers are are going to be spending more than $100 billion to come out with more than a hundred models of battery electric vheicles which also includes PHEVs and the fear is these vehicles aren’t going to sell in the numbers that automakers and industry analysts may have expected. But forecasts are just that, forecasts, even as U.S. EV sales surge into 2024 suggest momentum. So there’s a valid argument to be made that they’ll either overshoot the true mark or come in way below the actual amount. With nine U.S. states mandating that 15% of new cars sold be EVs by 2025, you could say that at least automakers have supporters in state government helping to push the new technology into the hands of more drivers.

Still, it’s anyone’s guess as to what true adoption will be, and a brief Q1 2024 market share dip underscores lingering volatility. The use of big data and just in time manufacturing will ensure that manufacturers will miss the mark on EVs by less than they have in the past, and will able to cope with breaking even on these vehicles for the sake of gobbling up precious early stage market share. After all, many vendors have up to this point been very willing to break even or make a loss on their lease-only EVs or on EV or hybrid financing in order to gain that share and build out their brand awareness and technical prowess. With some stops and starts, demand will meet supply or supply may need to meet demand but either way, the EV adoption wave is coming to a driveway near you.
