B.C. Hydro predicts 'bottleneck' as electric-vehicle demand ramps-up

Connected Home Energy Technologies integrate solar panels, smart meters, EV charging, battery storage, and IoT energy management to cut costs, optimize demand response, and monitor usage in real time for safer, lower-carbon homes.

Key Points

Devices and systems managing home energy: solar PV, smart meters, EV chargers, and storage to cut costs and emissions.

✅ Real-time visibility via apps, smart meters, and IoT sensors

✅ Integrates solar PV, batteries, and EV charging with the grid

✅ Enables demand response, lower bills, and lower carbon

Driven by advances in tech and the advent of high-speed internet connections, many of us now have easy access to a raft of information about the buildings we live in.

Thanks to the proliferation of hardware and software within the home, this trend shows no sign of letting up and comes in many different forms, from indoor air quality monitors to “smart” doorbells which provide us with visual, real-time notifications when someone is attempting to access our property.

Residential renewable electricity generation is also starting to gain traction, with a growing number of people installing solar panels in the hope of reducing bills and their environmental footprint.

In the U.S. alone, the residential solar market installed 738 megawatts of capacity in the third quarter of 2020, a 14% jump compared to the second quarter, according to a recent report from the Solar Energy Industries Association and Wood Mackenzie.

Earlier this month, California-headquartered SunPower — which specializes in the design, production and delivery of solar panels and systems — announced it was rolling out an app which will enable homeowners to assess and manage their energy generation, usage and battery storage settings with their mobile, as California looks to EVs for grid stability amid broader electrification.

The service will be available to customers using its SunPower Eqiunox system and represents yet another instance of how connected technologies can provide us with valuable information about how buildings operate.

Similar offerings in this increasingly crowded marketplace include so-called “smart” meters, which allow consumers to see how much energy they are using and money they are spending in real time.

Elsewhere products such as Hive, from Centrica, enable users to install a range of connected kit — from plugs and lighting to thermostats and indoor cameras — that can be controlled via an app on their cellphone and, in some cases, their voice. 

Connected car charging
Solar panels represent one way that sustainable tech can be integrated into homes. Other examples include the installation of charging points for electric vehicles, as EV growth challenges state grids in many markets.

With governments around the world looking to phase-out the sale of diesel and gasoline vehicles and encourage consumers to buy electric, and Model 3's utility impact underscoring likely shifts in demand, residential charging systems could become an integral part of the built environment in the years ahead.

Firms offering home-based, connected, charging include Pod Point and BP Pulse. Both of these services include apps which provide data such as how much energy has been used, the cost of charging and charge history.  

Another firm, Wallbox, recently announced it was launching its first electric vehicle charger for North American homes.

The company, which is based in Spain, said the system was compatible with all types of electric vehicles, would allow customers to schedule charges, and could be voice-controlled through Google Assistant and Amazon Alexa, while mobile energy storage promises added flexibility for strained grids.

Away from the private sector, governments are also making efforts to encourage the development of home charging infrastructure.

Over the weekend, U.K. authorities said the Electric Vehicle Homecharge Scheme — which gives drivers as much as £350 (around $487) toward a charging system — would be extended and expanded, targeting those who live in leasehold and rented properties, even as UK grid capacity for EVs remains under scrutiny.

Mike Hawes, chief executive of the Society of Motor Manufacturers and Traders, described the government’s announcement as “welcome and a step in the right direction.”

“As we race towards the phase out of sales of new petrol and diesel cars and vans by 2030, we need to accelerate the expansion of the electric vehicle charging network, and proper grid management can ensure EVs are accommodated at scale,” he added.

“An electric vehicle revolution will need the home and workplace installations this announcement will encourage, but also a massive increase in on-street public charging and rapid charge points on our strategic road network.”

Change afoot, but challenges ahead
As attempts to decarbonize buildings and society ramp up, the way our homes look and function could be on the cusp of quite a big shift.

“Grid-connected home generation technologies such as solar electric panels will be important in the shift to a 100% renewable electricity grid, but decarbonising the electricity supply is only one part of the transition,” Peter Tyldesley, chief executive of the Centre for Alternative Technology, told CNBC via email.

With reference to Britain, Tyldesley went on to explain how his organization envisaged “just under 10% of electricity in a future zero carbon society coming from solar PV, utilising 15-20% of … U.K. roof area.” This, he said, compared to over 75% of electricity coming from wind power. 

Heating, Tyldesley went on to state, represented “the bigger challenge.”

“To decarbonise the U.K.’s housing stock at the scale and speed needed to get to zero carbon, we’ll need to refurbish possibly a million houses every year for the next few decades to improve their insulation and airtightness and to install heat pumps or other non-fossil fuel heating,” he said.

“To do this, we urgently need a co-ordinated national programme with a commitment to multi-year government investment,” he added.

On the subject of buildings becoming increasingly connected, providing us with a huge amount of data about how they function, Tyldesley sought to highlight some of the opportunities this could create. 

“Studies of the roll out of smart metering technology have shown that consumers use less energy when they are able to monitor their consumption in real time, so this kind of technology can be a useful part of behaviour change programmes when combined with other forms of support for home efficiency improvements,” he said.

“The roll out of smart appliances can go one step further — responding to signals from the grid and, through vehicle-to-grid power, helping to shift consumption away from peak times towards periods when more renewable energy is available,” he added.

Clean Energy Buyers Alliance 2030 Goal targets a 90% carbon-free U.S. grid, accelerating power-sector decarbonization via corporate renewable energy procurement, market and policy reforms, and customer demand to enable net-zero electrification across industries.

Key Points

The Alliance's plan to reach a 90% carbon-free U.S. electricity system by 2030 via customer-driven markets and policy.

✅ Corporate buyers scale renewable PPAs and aggregation

✅ Market and policy reforms unlock clean power access

✅ Goal aligns with net-zero and widespread electrification

The Clean Energy Buyers Association (CEBA) and the Clean Energy Buyers Institute (CEBI), which together make up the Clean Energy Buyers Alliance, have announced a profound new aspiration for impact: a 90% carbon-free U.S. electricity system by 2030 and a global community of energy customers driving the global energy transition forward.

Alongside the two organizations’ bold new vision of the future – customer-driven clean energy for all – the Alliance will super-charge the work of its predecessor organizations, the Renewable Energy Buyers Alliance (REBA) and the REBA Institute, which represent the most iconic global companies with more than $6 trillion dollars in annual revenues and 14 million employees.

“This is the decisive decade for climate action and especially for decarbonization of the power sector,” said Miranda Ballentine, CEO of CEBA and CEBI. “To achieve a net-zero economy worldwide by 2050, the United States must lead. And the power sector must accelerate toward a 2030 timeline as electrification of other industries will be driving up power use.”

In the U.S. alone, more than 60% of electricity is consumed by the commercial and industrial sectors. Institutional energy customers have accelerated the deployment of clean energy solutions over the last 10 years to achieve increasingly ambitious greenhouse gas reduction targets, even as a federal coal plan remains under debate, and further cement the critical role of customers in decarbonizing the energy system. The Clean Energy Buyers Association Deal Tracker shows that 7.9 GW of new corporate renewable energy project announcements in the first three quarters of this year are equivalent to 40% of all new carbon free energy capacity added in the U.S. so far in 2021.

“With our new vision of customer-driven clean energy for all, we are also unveiling new organization brands,” Ballentine continued. “I’m excited to announce that REBA will become CEBA—the Clean Energy Buyers Association—and will focus on activating our community of energy customers and partners to deploy market and policy solutions for a carbon-free energy system. The REBA Institute will become the Clean Energy Buyers Institute (CEBI) and will focus on solving the toughest market and policy barriers to achieving a carbon-free energy system in collaboration with policymakers, leading philanthropies, and energy market stakeholders. Together, CEBA and CEBI will make up the new Clean Energy Buyers Alliance.”

To decarbonize the U.S. electricity system 90% by 2030, a goal aligned with California's 100% carbon-free mandate efforts, and to activate a community of customers driving clean energy around the world, the Clean Energy Buyers Alliance will drive three critical transformations to:

Unlock markets so that energy customers can use their buying power and market-influence, building on a historic U.S. climate deal this year, to accelerate electricity decarbonization.

Catalyze communities of energy customers to actively choose clean energy through Mission Innovation collaborations and to do more together than they could on their own.

Decarbonize the grid for all, since not every energy customer can or will use their buying power to choose clean energy.

“The Clean Energy Buyers Alliance is setting the bar for what energy buyers, utilities and governments should and need to be doing to achieve a carbon-free energy future,” said Michael Terrell, CEBA board chair and Director of Energy at Google. “This ambitious approach is a critical step in tackling climate change. The time for meaningful climate action is now and we must collectively be bolder and more ambitious in our actions in both the public and private sectors – starting today.”

This new vision of customer-driven clean energy for all is an unprecedented opportunity for every member of the Clean Energy Buyers Alliance community – from energy customers to providers to manufacturers – to all parties up and down the energy supply chain to lead the evolution of a new energy economy, which will require incentives to double investment in clean energy to rise to $4 trillion by 2030.

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.

France Plug-In Electric Car Sales September 2023 show rapid EV adoption: 45,872 plug-ins, 30% market share, BEV 19.6%, PHEV 10.2%, with Tesla Model Y leading registrations amid sustained year-over-year growth.

Key Points

France registered 45,872 plug-ins in September 2023, a 30% share, with BEVs at 19.6% and PHEVs at 10.2%.

✅ Tesla Model Y led BEVs with 5,035 registrations in September

✅ YTD plug-in share 25%; BEV 15.9%, PHEV 9.1% across passenger cars

✅ Total market up 9% YoY to 153,916; plug-ins up 35% YoY

New passenger car registrations in France increased in September by nine percent year-over-year to 153,916, mirroring global EV market growth trends, taking the year-to-date total to 1,286,247 (up 16 percent year-over-year).

The market has been expanding every month this year (recovering slightly from the 2020-2022 collapse and the period when EU EV share grew during lockdowns across the bloc) and also is becoming more and more electrifying thanks to increasing plug-in electric car sales.

According to L’Avere-France, last month 45,872 new passenger plug-in electric cars were registered in France (35 percent more than a year ago), which represented almost 30 percent of the market, aligning with the view that the age of electric cars is arriving ahead of schedule. That's a new record share for rechargeable cars and a noticeable jump compared to just over 24 percent a year ago.

What's even more impressive is that passenger all-electric car registrations increased to over 30,000 (up 34 percent year-over-year), taking a record share of 19.6 percent of the market. That's basically one in five new cars sold, and in the U.S., plug-ins logged 19 billion electric miles in 2021 as a benchmark.

Plug-in hybrids are also growing (up 35% year-over-year), and with 15,699 units sold, accounted for 10.2 percent of the market (a near record value).

Plug-in car sales in France – September 2023

So far this year, more than 341,000 new plug-in electric vehicles have been registered in France, including over 321,000 passenger plug-in cars (25 percent of the market), while in the U.S., EV sales are soaring into 2024 as well.

Plug-in car registrations year-to-date (YOY change):

• Passenger BEVs: 204,616 (up 45%) and 15.9% market share
• Passenger PHEVs: 116,446 (up 31%) and 9.1% market share
• Total passenger plug-ins: 321,062 (up 40%) and 25% market share
• Light commercial BEVs: 20,292 (up 111%)
• Light commercial PHEVs: 281 (down 38%)
• Total plug-ins: 341,635 (up 43%)

For reference, in 2022, more than 346,000 new plug-in electric vehicles were registered in France (including almost 330,000 passenger cars, which was 21.5 percent of the market).

We can already tell that the year 2023 will be very positive for electrification in France, with a potential to reach 450,000 units or so, though new EV incentive rules could reshape the competitive landscape.

Models
In terms of individual models, the Tesla Model Y again was the most registered BEV with 5,035 new registrations in September. This spectacular result enabled the Model Y to become the fifth best-selling model in the country last month (Tesla, as a brand, was seventh).

The other best-selling models are usually small city cars - Peugeot e-208 (3,924), Dacia Spring (2,514), Fiat 500 electric (2,296), and MG4 (1,945), amid measures discouraging Chinese EVs in France. Meanwhile, the best-selling electric Renault - the Megane-e - was outside the top five BEVs, which reveals to us how much has changed since the Renault Zoe times.

After the first nine months of the year, the top three BEVs are the Tesla Model Y (27,458), Dacia Spring (21,103), and Peugeot e-208 (19,074), slightly ahead of the Fiat 500 electric (17,441).

Faroe Islands Tidal Kites harness predictable ocean energy with underwater turbines by Minesto, flying figure-eight paths in fjords to amplify tidal power and deliver renewable electricity to SEV's grid near Vestmanna at megawatt scale.

Key Points

Subsea turbines that fly figure-eight paths to harvest tidal currents, delivering reliable renewable power to the grid.

✅ Figure-eight control amplifies speed vs. ambient current

✅ Predictable baseload complementing wind and hydro

✅ 1.2 MW Dragon-class units planned for Faroese fjords

Known as "sea dragons" or "tidal kites", they look like aircraft, but these are in fact high-tech tidal turbines, part of broader ocean and river power efforts generating electricity from the power of the ocean.

The two kites - with a five-metre (16ft) wingspan - move underwater in a figure-of-eight pattern, absorbing energy from the running tide. They are tethered to the fjord seabed by 40-metre metal cables.

Their movement is generated by the lift exerted by the water flow - just as a plane flies by the force of air flowing over its wings.

Other forms of tidal power use technology similar to terrestrial wind turbines, and emerging kite-based wind power shows the concept's versatility, but the kites are something different.

The moving "flight path" allows the kite to sweep a larger area at a speed several times greater than that of the underwater current. This, in turn, enables the machines to amplify the amount of energy generated by the water alone.

An on-board computer steers the kite into the prevailing current, then idles it at slack tide, maintaining a constant depth in the water column. If there were several kites working at once, the machines would be spaced far enough apart to avoid collisions.

The electricity is sent via the tethering cables to others on the seabed, and then to an onshore control station near the coastal town of Vestmanna.

The technology has been developed by Swedish engineering firm Minesto, founded back in 2007 as a spin-off from the country's plane manufacturer, Saab.

The two kites in the Faroe Islands have been contributing energy to Faroe's electricity company SEV, and the islands' national grid, on an experimental basis over the past year.

Each kite can produce enough electricity to power approximately 50 to 70 homes.

But according to Minesto chief executive, Martin Edlund, larger-scale beasts will enter the fjord in 2022.

"The new kites will have a 12-metre wingspan, and can each generate 1.2 megawatts of power [a megawatt is 1,000 kilowatts]," he says. "We believe an array of these Dragon-class kites will produce enough electricity to power half of the households in the Faroes."

The 17 inhabited Faroe islands are an autonomous territory of Denmark. Located halfway between Shetland and Iceland, in a region where U.K. wind lessons resonate, they are home to just over 50,000 people.

Known for their high winds, persistent rainfall and rough seas, the islands have never been an easy place to live. Fishing is the primary industry, accounting for more than 90% of all exports.

The hope for the underwater kites is that they will help the Faroe Islands achieve its target of net-zero emission energy generation by 2030, with advances in wave energy complementing tidal resources along the way.

While hydro-electric power currently contributes around 40% of the islands' energy needs, wind power contributes around 12% and fossil fuels - in the form of diesel imported by sea - still account for almost half.

Mr Edlund says that the kites will be a particularly useful back-up when the weather is calm. "We had an unusual summer in 2021 in Faroes, with about two months with virtually no wind," he says.

"In an island location there is no possibility of bringing in power connections from another country, and tidal energy for remote communities can help, when supplies run low. The tidal motion is almost perpetual, and we see it as a crucial addition to the net zero goals of the next decade."

Minesto has also been testing its kites in Northern Ireland and Wales, where offshore wind in the UK is powering rapid growth, and it plans to install a farm off the coast of Anglesey, plus projects in Taiwan and Florida.

The Faroe Islands' drive towards more environmental sustainability extends to its wider business community, with surging offshore wind investment providing global momentum. The locals have formed a new umbrella organisation - Burðardygt Vinnulív (Faroese Business Sustainability Initiative).

It currently has 12 high-profile members - key players in local business sectors such as hotels, energy, salmon farming, banking and shipping.

The initiative's chief executive - Ana Holden-Peters - believes the strong tradition of working collaboratively in the islands has spurred on the process. "These businesses have committed to sustainability goals which will be independently assessed," she says.

"Our members are asking how they can make a positive contribution to the national effort. When people here take on a new idea, the small scale of our society means it can progress very rapidly."

One of the islands' main salmon exporters - Hiddenfjord - is also doing its bit, by ceasing the air freighting of its fresh fish. Thought to be a global first for the Atlantic salmon industry, it is now exporting solely via sea cargo instead.

According to the firm's managing director Atli Gregersen this will reduce its transportation CO2 emissions by more than 90%. However it is a bold move commercially as it means that its salmon now takes much longer to get to key markets.

For example, using air freight, it could get its salmon to New York City within two days, but it now takes more than a week by sea.

What has made this possible is better chilling technology that keeps the fresh fish constantly very cold, but without the damaging impact of deep freezing it. So the fish is kept at -3C, rather than the -18C or below of typical commercial frozen food transportation.

"It's taken years to perfect a system that maintains premium quality salmon transported for sea freight rather than plane," says Mr Gregersen. "And that includes stress-free harvesting, as well as an unbroken cold-chain that is closely monitored for longer shelf life.

"We hope, having shown it can be done, that other producers will follow our lead - and accept the idea that salmon were never meant to fly."

Back in the Faroe Island's fjords, a firm called Ocean Rainforest is farming seaweed.

The crop is already used for human food, added to cosmetics, and vitamin supplements, but the firm's managing director Olavur Gregersen is especially keen on the potential of fermented seaweed being used as an additive to cattle feed.

He points to research which appears to show that if cows are given seaweed to eat it reduces the amount of methane gas that they exhale.

"A single cow will burp between 200 and 500 litres of methane every day, as it digests," says Mr Gregersen. "For a dairy cow that's three tonnes per animal per year.

"But we have scientific evidence to show that the antioxidants and tannins in seaweed can significantly reduce the development of methane in the animal's stomach. A seaweed farm covering just 10% of the largest planned North Sea wind farm could reduce the methane emissions from Danish dairy cattle by 50%."

The technology that Ocean Rainforest uses to farm its four different species of seaweed is relatively simple. Tiny algal seedlings are affixed to a rope which dangles in the water, and they grow rapidly. The line is lifted using a winch and the seaweed strands simply cut off with a knife. The line goes back into the water, and the seaweed starts growing again.

Currently, Ocean Rainforest is harvesting around 200 tonnes of seaweed per annum in the Faroe Islands, but plans to scale this up to 8,000 tonnes by 2025. Production may also be expanded to other areas in Europe and North America.

U.S. Renewable Energy Share 2022 leads electricity generation trends, as wind and solar outpace nuclear and coal, per EIA data, with hydropower gains and grid growth highlighting rapid, sustainable capacity expansion nationwide.

Key Points

Renewables supplied over 25% of U.S. electricity in 2022, as wind and solar outpaced nuclear with double-digit growth.

✅ Renewables provided 25.52% of U.S. power Jan-Apr 2022.

✅ Wind and solar beat nuclear by 17.96% in April.

✅ Solar up 28.93%, wind up 24.25%; hydropower up 9.99%.

During the first four months of 2022, electrical generation by renewable energy sources accounted for over 25% of the nation’s electricity, projected to soon be about one-fourth as growth continues. In April alone, renewables hit a record April share of 29.3% — an all-time high.

And for the first time ever, the combination of just wind power and solar produce more electricity in April than the nation’s nuclear power plants — 17.96% more.

This is according to a SUN DAY Campaign analysis of data in EIA’s Electric Power Monthly report. The report also reveals that during the first third of this year, solar (including residential) generation climbed by 28.93%, while wind increased by 24.25%. Combined, solar and wind grew by 25.46% and accounted for more than one-sixth (16.67%) of U.S. electrical generation (wind: 12.24%, solar: 4.43%).

Hydropower also increased by 9.99% during the first four months of 2022. However, wind alone provided 70.89% more electricity than did hydropower. Together with contributions from geothermal and biomass, the mix of renewable energy sources expanded by 18.49%, and building on its second-most U.S. source in 2020 status helped underscore momentum as it provided about 25.5% of U.S. electricity during the first four months of 2022.

For the first third of the year, renewables surpassed coal and nuclear power by 26.13% and 37.80% respectively. In fact, electrical generation by coal declined by 3.94% compared to the same period in 2021 while nuclear dropped by 1.80%.

“Notwithstanding headwinds such as the COVID pandemic, grid access problems, and disruptions in global supply chains, solar and wind remain on a roll,” noted the SUN DAY Campaign’s executive director Ken Bossong. “Moreover, by surpassing nuclear power by ever greater margins, they illustrate the foolishness of trying to revive the soon-to-retire Diablo Canyon nuclear plant in California and the just-retired Palisades reactor in Michigan rather than focusing on accelerating renewables’ growth.”
