Harbour Air Electric Seaplanes pioneer zero-emission aviation with battery-powered de Havilland Beaver flights, pursuing Transport Canada certification for safe, fossil fuel-free service across Vancouver Island routes connecting Vancouver, Victoria, Nanaimo, and beyond.

Key Points

Battery-powered, zero-emission floatplanes by Harbour Air pursuing Transport Canada certification to carry passengers.

✅ 29-minute test flight on battery power alone

✅ New lighter, longer-lasting battery supplier partnership

✅ Aiming to electrify entire 42-aircraft Beaver/Otter fleet

Float plane operator Harbour Air is getting closer to achieving its goal of flying to and from Vancouver Island without fossil fuels, following its first point-to-point electric flight milestone.

A recent flight of the company’s electric de Havilland Beaver test plane saw the aircraft remain aloft for 29 minutes on battery power alone, a sign of an emerging aviation revolution underway.

Harbour Air president Randy Wright says the company has joined with a new battery supplier to provide a lighter and longer-lasting power source, a high-flying example of research investment in the sector.

The company hopes to get Transport Canada certification to start carrying passengers on electric seaplanes by 2023, as projects like the electric-ready Kootenay Lake ferry come online.

"This is all new to Transport, so they've got to make sure it's safe just like our aircraft that are running today,” Wright said Wednesday. “They're working very hard at this to get this certified because it's a first in the world."

Parallel advances in marine electrification, such as electric ships on the B.C. coast, are informing clean-transport goals across the province.

Before the pandemic, Harbour Air flew approximately 30,000 commercial flights annually, along corridors also served by BC Ferries hybrid ships today, between Vancouver, Victoria, Nanaimo, Whistler, Seattle, Tofino, Salt Spring Island, the Sunshine Coast and Comox.

Wright says the company plans to eventually electrify its entire fleet of 42 de Havilland Beaver and Otter aircraft, reflecting a broader shift that includes CIB-backed electric ferries in B.C.

Sicily Green Hydrogen accelerates decarbonization via renewable energy, wind farm electrolysis, hydrogen storage, and distribution from Enel Green Power and Sapio at the NextHy industrial lab in Carlentini and Sortino Sicily hub.

Key Points

Sicily Green Hydrogen is an Enel-Sapio plan to produce hydrogen via wind electrolysis for industrial decarbonization.

✅ 4 MW electrolyzer powered by Carlentini wind farm

✅ Estimated 200+ tons annual green H2 production capacity

✅ Market distribution managed by Sapio across Sicily

This green hydrogen will be produced at the Sicilian industrial plant, an innovative hub that puts technology at the service of the energy transition, echoing hydrogen innovation funds that support similar goals worldwide

Activating a supply of green hydrogen produced using renewable energy from the Carlentini wind farm in eastern Sicily is the focus of the agreement signed by Enel Green Power and Sapio. The agreement provides for the sale to Sapio of the green hydrogen that will be produced, stored in clean energy storage facilities and made available from 2023 at the Carlentini and Sortino production sites, home to Enel Green Powers futuristic NextHy innitiative. Sapio will be responsible for developing the market and handling the distribution of renewable hydrogen to the end customer.

In contexts where electrification is not easily achievable, green hydrogen is the key solution for decarbonization as it is emission-free and offers a potential future for power companies alongside promising development prospects, commented Salvatore Bernabei, CEO of Enel Green Power. For this reason we are excited about the agreement with Sapio. It is an agreement that looks to the future by combining technological innovation and sustainable production.

Sapio is strongly committed to contributing to the EUs achievement of the UN SDGs, commented Alberto Dossi, President of the Sapio Group, and with this project we are taking a firm step towards sustainable development in our country. The agreement with EGP also gives us the opportunity to integrate green hydrogen into our business model, as jurisdictions propose hydrogen-friendly electricity rates to grow the hydrogen economy, which is based on our strong technological expertise in hydrogen and its distribution over 100 years in business. In this way we will also be able to give further support to the industrial activities we are already carrying out in Sicily.

The estimated 200+ tons of production capacity of the Sicilian hub is the subject of the annual supply foreseen in the agreement. Once fully operational, the green hydrogen will be produced mainly by a 4 MW electrolyzer, which is powered exclusively by the renewable energy of the existing wind farm, and to a lesser extent by the state-of-the-art electrolysis systems tested in the platform. Launched by Enel Green Power in September 2021, NextHys Hydrogen Industrial Lab is a unique example of an industrial laboratory in which production activity is constantly accompanied by technological research. In addition to the sectors reserved for full-scale production, there are also areas dedicated to testing new electrolyzers, components such as valves and compressors, and innovative storage solutions based on liquid and solid means of storage: in line with Enels open-ended approach, this activity will be open to the collaboration of more than 25 entities including partners, stakeholders and innovative startups. The entire complex is currently undergoing an environmental impact assessment at the Sicily Regions Department of Land and Environment.

It is an ambitious project with a sustainable energy source at its heart that will be developed at every link in the chain: thanks to the agreement with Sapio, in fact, at NextHy green hydrogen will now not only be produced, stored and moved on an industrial scale, but also purchased and used by companies that have understood that green hydrogen is the solution for decarbonizing their production processes. In this context, this experimental approach that is open to external contributions will allow the Enel Green Power laboratory team to test the project on an industrial scale, so as to create the best conditions for a commercial environment that can make the most of all present and future technologies for the generation, storage and transport of green hydrogen, including green hydrogen microgrids that demonstrate scalable integration. It is an initiative consistent with Enels Open Innovability spirit: meeting the challenges of the energy transition by focusing on innovation, ideas and their transformation into reality.

Vehicle-to-Home (V2H) Power enables EVs to act as backup generators and home batteries, using bidirectional charging, inverters, and rooftop solar to cut energy costs, stabilize the grid, and provide resilient, outage-proof electricity.

Key Points

Vehicle-to-Home (V2H) Power lets EV batteries run household circuits via bidirectional charging and an inverter.

✅ Cuts energy bills using solar, time-of-use rates, and storage

✅ Provides resilient backup during outages, storms, and blackouts

✅ Enables grid services via V2G/V2H with smart chargers

When the power went out at Nate Graham’s New Mexico home last year, his family huddled around a fireplace in the cold and dark. Even the gas furnace was out, with no electricity for the fan. After failing to coax enough heat from the wood-burning fireplace, Graham’s wife and two children decamped for the comfort of a relative’s house until electricity returned two days later.

The next time the power failed, Graham was prepared. He had a power strip and a $150 inverter, a device that converts direct current from batteries into the alternating current needed to run appliances, hooked up to his new Chevy Bolt, an electric vehicle. The Bolt’s battery powered his refrigerator, lights and other crucial devices with ease. As the rest of his neighborhood outside Albuquerque languished in darkness, Graham’s family life continued virtually unchanged. “It was a complete game changer making power outages a nonissue,” says Graham, 35, a manager at a software company. “It lasted a day-and-a-half, but it could have gone much longer.”

Today, Graham primarily powers his home appliances with rooftop solar panels and, when the power goes out, his Chevy Bolt. He has cut his monthly energy bill from about $220 to $8 per month. “I’m not a rich person, but it was relatively easy,” says Graham “You wind up in a magical position with no [natural] gas, no oil and no gasoline bill.”

Graham is a preview of what some automakers are now promising anyone with an EV: An enormous home battery on wheels that can reverse the flow of electricity to power the entire home through the main electric panel.

Beyond serving as an emissions-free backup generator, the EV has the potential of revolutionizing the car’s role in American society, with California grid programs piloting vehicle-to-grid uses, transforming it from an enabler of a carbon-intensive existence into a key step in the nation’s transition into renewable energy.

Home solar panels had already been chipping away at the United States’ centralized power system, forcing utilities to make electricity transfer a two-way street. More recently, home batteries have allowed households with solar arrays to become energy traders, recharging when electricity prices are low, replacing grid power when prices are high, and then sell electricity back to the grid for a profit during peak hours.

But batteries are expensive. Using EVs makes this kind of home setup cheaper and a real possibility for more Americans as the American EV boom accelerates nationwide.

So there may be a time, perhaps soon, when your car not only gets you from point A to point B, but also serves as the hub of your personal power plant.

I looked into new vehicles and hardware to answer the most common questions about how to power your home (and the grid) with your car.

Why power your home with an EV battery

America’s grid is not in good shape. Prices are up and reliability is down, and many state power grids face new challenges from rising EV adoption. Since 2000, the number of major outages has risen from less than two dozen to more than 180 per year, based on federal data, the Wall Street Journal reports. The average utility customer in 2020 endured about eight hours of power interruptions, double the previous decade.

Utilities’ relationship with their customers is set to get even rockier. Residential electricity prices, which have risen 21 percent since 2008, are predicted to keep climbing as utilities spend more than $1 trillion upgrading infrastructure, erecting transmission lines for renewable energy and protecting against extreme weather, even though grids can handle EV loads with proper management and planning.

U.S. homeowners, increasingly, are opting out. About 8 percent of them have installed solar panels. An increasing number are adding home batteries from companies such as LG, Tesla and Panasonic. These are essentially banks of battery cells, similar to those in your laptop, capable of storing energy and discharging electricity.

EnergySage, a renewable energy marketplace, says two-thirds of its customers now request battery quotes when soliciting bids for home solar panels, and about 15 percent install them. This setup allows homeowners to declare (at least partial) independence from the grid by storing and consuming solar power overnight, as well as supplying electricity during outages.

But it doesn’t come cheap. The average home consumes about 20 kilowatt-hours per day, a measure of energy over time. That works out to about $15,000 for enough batteries on your wall to ensure a full day of backup power (although the net cost is lower after incentives and other potential savings).

How an EV battery can power your home

Ford changed how customers saw their trucks when it rolled out a hybrid version of the F-150, says Ryan O’Gorman of Ford’s energy services program. The truck doubles as a generator sporting as many as 11 outlets spread around the vehicle, including a 240-volt outlet typically used for appliances like clothes dryers. During disasters like the 2021 ice storm that left millions of Texans without electricity, Ford dealers lent out their hybrid F-150s as home generators, showing how mobile energy storage can bring new flexibility during outages.

The Lightning, the fully electric version of the F-150, takes the next step by offering home backup power. Under each Lightning sits a massive 98 kWh to 131 kWh battery pack. That’s enough energy, Ford estimates, to power a home for three days (10 days if rationing). “The vehicle has an immense amount of power to move that much metal down the road at 80 mph,” says O’Gorman.

Electric Vehicle Ownership Costs include lower maintenance, repair, and fuel expenses; Consumer Reports shows BEV and PHEV TCO beats ICE over 200,000 miles, with per-mile savings compounding through electricity prices and reduced service.

Key Points

Lifetime EV expenses, typically lower than ICE, due to cheaper electricity, reduced maintenance, and fewer repairs.

✅ BEV: $0.012/mi to 50k; $0.028/mi after; vs ICE up to $0.06/mi

✅ PHEV: $0.021/mi to 50k; $0.031/mi after; still below ICE

✅ Savings increase over 200k miles from fuel and service reductions

Electric vehicles are a relatively new technology, and the EV age is arriving ahead of schedule today. Even though we technically saw the first battery-powered vehicles more than 100 years ago, they haven’t really become viable transportation in the modern world until recently, and they are greener than ever in all 50 states as the grid improves.

As viable as they may now be, however, it still seems they’re unarguably more expensive than their conventional internal-combustion counterparts, prompting many to ask whether it’s time to buy an electric car today. Well, until now.

Lower maintenence costs and the lower price of electricity versus gasoline (see the typical cost to charge an electric vehicle in most regions) actually make electric cars much cheaper in the long run, despite their often higher purchase price, according to a new survey by Consumer Reports. The information was collected using annual reliability surveys conducted by CR in 2019 and 2020.

In the first 50,000 miles (80,500 km), battery electric vehicles cost just US$0.012 per mile for maintenence and repairs, while plug-in hybrid models bump that number up to USD$0.021. Compare these numbers to the typical USD$0.028 cost for internal combustion vehicles, and it becomes clear the more you drive, the more you will save, and across the U.S. plug-ins logged 19 billion electric miles in 2021 to prove the point. After 50,000 miles, the costs for BEV and PHEV vehicles is US$0.028 and US$0.031 respectively, while ICE vehicles jump to US$0.06 per mile.

To put it more practically, if you chose to buy a Model 3 instead of a BMW 330i, you’d see a total US$17,600 in savings over the lifetime of the vehicle, aligning with evidence that EVs are better for the planet and your budget as well, based on average driving. In the SUV sector, buying a Tesla Model Y instead of a Lexus crossover would save US$13,400 (provided the former’s roof doesn’t fly off) and buying a Nissan Leaf over a Honda Civic would save US$6,000 over the lifetime of the vehicles.

CR defines the vehicle’s “lifetime” as 200,000 miles (320,000 km). Ergo the final caveat: while it sounds like driving electric means big savings, you might only see those returns after quite a long period of ownership, though some forecasts suggest that within a decade adoption will be nearly universal for many drivers.

Home Solar Cost vs Utility Bills compares electricity rates, ROI, incentives, and battery storage, explaining payback, financing, and grid fees while highlighting long-term savings, rate volatility, and backup power resilience for homeowners.

Key Points

Compares home solar pricing and financing to utility rates, outlining savings, incentives, ROI, and backup power value.

✅ Average retail rates rose 59% in 20 years; volatility persists

✅ Typical 7.15 kW system costs $18,950 before incentives

✅ Federal ITC and state rebates improve ROI and payback

When shopping for a home solar system, sometimes the quoted price can leave you wondering why someone would move forward with something that seems so expensive. 

When compared with the status quo, electricity delivered from the utility, the price may not seem so high after all. First, pv magazine will examine the status quo, and how much you can expect to pay for power if you don’t get solar panels. Then, we will examine the average cost of solar arrays today and introduce incentives that boost home solar value.

The cost of doing nothing

Generally, early adopters have financially benefited from going solar by securing price certainty and stemming the impact of steadily increasing utility-bill costs, particularly for energy-insecure households who pay more for electricity.

End-use residential electric customers pay an average of $0.138/kWh in the United States, according to the Energy Information Administration (EIA). In California, that rate is $0.256/kWh, it averages $0.246/kWh across New England, $0.126/kWh in the South Atlantic region, and $0.124/kWh in the Mountain West region.

EIA reports that the average home uses 893 kWh per month, so based on the average retail rate of $0.138/kWh, that’s an electric bill of about $123 monthly, or $229 monthly in California.

Over the last 20 years, EIA data show that retail electricity prices have increased 59% across the United States, with evidence indicating that renewables are not making electricity more expensive, suggesting other factors have driven costs higher, or 2.95% each year.

This means based on historical rates, the average US homeowner can expect to pay $39,460 over the next 20 years on electricity bills. On average, Californians could pay $73,465 over 20 years.

Recent global events show just how unstable prices can be for commodities, and energy is no exception here, with solar panel sales doubling in the UK as homeowners look to cut soaring bills. What will your utility bill cost in 20 years?

These estimated bills also assume that energy use in the home is constant over 20 years, but as the United States electrifies its homes, adds more devices, and adopts electric vehicles, it is fair to expect that many homeowners will use more electricity going forward.

Another factor that may exacerbate rate raising is the upgrade of the national transmission grid. The infrastructure that delivers power to our homes is aging and in need of critical upgrades, and it is estimated that a staggering $500 billion will be spent on transmission buildout by 2035. This half-trillion-dollar cost gets passed down to homeowners in the form of raised utility bill rates.

The benefit of backup power may increase as time goes on as well. Power outages are on the rise across the United States, and recent assessments of the risk of power outages underscore that outages related to severe weather events have doubled in the last 20 years. Climate change-fueled storms are expected to continue to rise, so the role of battery backup in providing reliable energy may increase significantly.

The truth is, we don’t know how much power will cost in 20 years. Though it has increased 59% across the nation in the last 20 years, there is no way to be certain what it will cost going forward. That is where solar has a benefit over the status quo. By purchasing solar, you are securing price certainty going forward, making it easier to budget and plan for the future.

So how do these costs compare to going solar?

Cost of solar

As a general trend, prices for solar have fallen. In 2010, it cost about $40,000 to install a residential solar system, and since then, prices have fallen by as much as 70%, and about 37% in the last five years. However, prices have increased slightly in 2022 due to shipping costs, materials costs, and possible tariffs being placed on imported solar goods, and these pressures aren’t expected to be alleviated in the near-term.

When comparing quotes, the best metric for an apples-to-apples comparison is the cost per watt. Price benchmarking by the National Renewable Energy Laboratory shows the average cost per watt for the nation was $2.65/W DC in 2021, and the average system size was 7.15 kW. So, an average system would cost about $18,950. With 12.5 kWh of battery energy storage, the average cost was $4.26/W, representing an average price tag of $30,460 with batteries included.

The prices above do not include any incentives. Currently, the federal government applies a 26% investment tax credit to the system, bringing down system costs for those who qualify to $14,023 without batteries, and $22,540 with batteries. Compared to the potential $39,460 in utility bills, buying a solar system outright in cash appears to show a clear financial benefit.

Many homeowners will need financing to buy a solar system. Shorter terms can achieve rates as low as 2.99% or less, but financing for a 20-year solar loan typically lands between 5% to 8% or more. Based on 20-year, 7% annual percentage rate terms, a $14,000 system would total about $26,000 in loan payments over 20 years, and the system with batteries included would total about $42,000 in loan payments.

Often when you adopt solar, the utility will still charge you a grid access fee even if your system produces 100% of your needs. These vary from utility to utility but are often around $10 a month. Over 20 years, that equates to about $2,400 that you’ll still need to pay to the utility, plus any costs for energy you use beyond what your system provides.

Based on these average figures, a homeowner could expect to see as much as $12,000 in savings with a 20-year financed system. Homeowners in regions whose retail energy price exceeds the national average could see savings in multiples of that figure.

Though in this example batteries appear to be marginally more expensive than the status quo over a 20-year term, they improve the home by adding the crucial service of backup power, and as battery costs continue to fall they are increasingly being approved to participate in grid services, potentially unlocking additional revenue streams for homeowners.

Another thing to note is most solar systems are warranted for 25 years rather than the 20 used in the status quo example. A panel can last a good 35 years, and though it will begin to produce less in old age, any power produced by a panel you own is money back in your pocket.

Incentives and home value

Many states have additional incentives to boost the value of solar, too, and federal proposals to increase solar generation tenfold could remake the U.S. electricity system. Checking the Database of State Incentives for Renewables (DSIRE) will show the incentives available in your state, and a solar representative should be able to walk you through these benefits when you receive a quote. State incentives change frequently and vary widely, and in some cases are quite rich, offering thousands of dollars in additional benefits.

Another factor to consider is home value. A study by Zillow found that solar arrays increase a home value by 4.1% on average. For a $375,000 home, that’s an increase of $15,375 in value. In most states home solar is exempt from property taxes, making it a great way to boost value without paying taxes for it.

Bottom line

We’ve shared a lot of data on national averages and the potential cost of power going forward, but is solar for you? In the past, early adopters have been rewarded for going solar, and celebrate when they see $0 electric bills paid to the utility company.

Each home is different, each utility is different, and each homeowner has different needs, so evaluating whether solar is right for your home will take a little time and analysis. Representatives from solar companies will walk you through this analysis, and it’s generally a good rule of thumb to get at least three quotes for comparison.

A great resource for starting your research is the Solar Calculator developed by informational site SolarReviews. The calculator offers a quote and savings estimate based on local rates and incentives available to your area. The website also features reviews of installers, equipment, and more.

Some people will save tens of thousands of dollars in the long run with solar, while others may witness more modest savings. Solar will also provide the home clean, local energy, and U.S. solar generation is projected to reach 20% by 2050 as capacity expands, making an impact both on mitigating climate change and in supporting local jobs.

One indisputable benefit of solar is that it will offer greater clarity into what your electricity bills will cost over the next couple of decades, rather than leaving you exposed to whatever rates the utility company decides to charge in the future.

Arvato Ontario Solar Power Plant advances sustainability with rooftop photovoltaic panels, PPA financing, and green electricity, generating 800,000 kWh annually to cut logistics emissions, reduce energy costs, and support carbon-neutral supply chain operations.

Key Points

A rooftop PV system under a PPA, supplying low-cost green power to Arvato's Ontario, CA distribution center.

✅ 1,160 panels produce 800,000 kWh of renewable power yearly

✅ PPA model avoids upfront costs and lowers electricity rates

✅ Cuts center emissions by 72%; 45% roof coverage

Arvato continues to invest consistently in the sustainability of its distribution centers. To this end, the first solar power plant in the focus market has now been commissioned on the roof of the distribution center in Ontario, California. The solar power plant has 1,160 solar panels and generates more than 800,000 kilowatt hours (kWh) of green electricity annually. This reduces electricity costs and, with advances in battery storage, further cuts the logistics center's greenhouse gas emissions. Previously, the international supply chain and e-commerce service provider had converted five other distribution centers in the USA to green electricity.

The project started as early as November 2019 with an intensive site investigation. An extensive catalogue of measures and criteria had to be worked through to install and commission the solar power plant on the roof system. After a rigorous process involving numerous stakeholders, the new solar modules were installed in August 2022, similar to utility-scale deployments like the largest solar array in Washington seen recently. However, further approvals and permits were required before the solar system could be officially commissioned, a common step for solar power plants worldwide. Once official permission for the operation was granted, the switch could be flipped in February 2023, and production of environmentally friendly solar electricity could begin.

The photovoltaic system is operated under a Purchase Power Agreement (PPA), a model widely used in corporate renewable energy projects today. This unique financing mechanism is available in twenty-six U.S. states, including California. While a third-party developer installs, owns and operates the solar panels, Arvato purchases the electricity generated. This allows companies in the U.S. to support clean energy projects while buying low-cost electricity without having to finance upfront costs. "The PPA and the resulting benefits were quite critical to the success of this project," says Christina Greenwell, Microsoft AOC F&L Client Services Manager at Arvato, who managed the project from start to finish. "It allows us to reduce our electricity costs while supporting Bertelsmann's ambitious goal of becoming carbon neutral by 2030."

The 1,160 solar panels were added to an existing system of 920 panels owned by the logistics center's landlord. In total, the panels now cover 45 percent of the roof space at the Ontario distribution center. The emissions generated by the distribution center are now reduced by 72 percent with the new solar panels and clean power generation. As Bertelsmann plans to switch all its sites worldwide to 100 percent green electricity, renewable energy certificates will, as seen when Bimbo Canada signed agreements to offset 100 percent of its electricity for its operations, offset the remaining emissions.

"The new solar power plant is a significant step on our path to carbon neutrality and demonstrates our commitment to finding innovative solutions that reduce our carbon footprint," said Mitat Aydindag, President of North America at Arvato. "All employees at the site are pleased that our Ontario distribution center is now a pioneer and is providing effective support in achieving our ambitious climate goal in 2030."

Similar facility-level efforts include the Bright Feeds Berlin solar project underscoring momentum across industrial operations.
