Electric vehicles can now power your home for three days

First Glasgow Electric Buses will transform the Caledonia depot with 160 charging points, zero-emission operations, grid upgrades, and rapid charging, supported by Transport Scotland funding and Alexander Dennis manufacturing for cleaner urban routes by 2023.

Key Points

Electric single-deckers at Caledonia depot with 160 chargers and upgrades, delivering zero-emission service by 2023

✅ 160 charging points; 4-hour rapid recharge capability

✅ Grid upgrades to power a fleet equal to a 10,000-person town

✅ Supported by Transport Scotland; built by Alexander Dennis

First Bus will install 160 charging points and replace half its fleet with electric buses at its Caledonia depot in Glasgow.

The programme is expected to be completed in 2023, similar to Metro Vancouver's battery-electric rollout milestones, with the first 22 buses arriving by autumn.

Charging the full fleet will use the same electricity as it takes to power a town of 10,000 people.

The scale of the project means changes are needed to the power grid, a challenge highlighted in global e-bus adoption analysis, to accommodate the extra demand.

First Glasgow managing director Andrew Jarvis told BBC Scotland: "We've got to play our part in society in changing how we all live and work. A big part of that is emissions from vehicles.

"Transport is stubbornly high in terms of emissions and bus companies need to play their part, and are playing their part, in that zero emission journey."

First Bus currently operates 337 buses out of its largest depot with another four sites across Glasgow.

The new buses will be built by Alexander Dennis at its manufacturing sites in Falkirk and Scarborough.

The transition requires a £35.6m investment by First with electric buses costing almost double the £225,000 bill for a single decker running on diesel.

But the company says maintenance and running costs, as seen in St. Albert's electric fleet results, are then much lower.

The buses can run on urban routes for 16 hours, similar to Edmonton's first e-bus performance, and be rapidly recharged in just four hours.

This is a big investment which the company wouldn't be able to achieve on its own.

Government grants only cover 75% of the difference between the price of a diesel and an electric bus, similar to support for B.C. electric school buses programmes, so it's still a good bit more expensive for them.

But they know they have to do it as a social responsibility, and large-scale initiatives like US school bus conversions show the direction of travel, and because the requirements for using Low Emissions Zones are likely to become stricter.

The SNP manifesto committed to electrifying half of Scotland's 4,000 or so buses within two years.

Some are questioning whether that's even achievable in the timescale, though TTC's large e-bus fleet offers lessons, given the electricity grid changes that would be necessary for charging.

But it's a commitment that environmental groups will certainly hold them to.

Transport Scotland is providing £28.1m of funding to First Bus as part of the Scottish government's commitment to electrify half of Scotland's buses in the first two years of the parliamentary term.

Net Zero Secretary Michael Matheson said: "It's absolute critical that we decarbonise our transport system and what we have set out are very ambitious plans of how we go about doing that.

"We've set out a target to make sure that we decarbonise as many of the bus fleets across Scotland as possible, at least half of it over the course of the next couple of years, and we'll set out our plans later on this year of how we'll drive that forward."

Transport is the single biggest source of greenhouse gas emissions in Scotland which are responsible for accelerating climate change.

In 2018 the sector was responsible for 31% of the country's net emissions.

Electric bus
First Glasgow has been trialling two electric buses since January 2020.

Driver Sally Smillie said they had gone down well with passengers because they were much quieter than diesel buses.

She added: "In the beginning it was strange for them not hearing them coming but they adapt very easily and they check now.

"It's a lot more comfortable. You're not feeling a gear change and the braking's smoother. I think they're great buses to drive."

Electric Fleet Grid Planning aligns utilities, charging infrastructure, distribution upgrades, and substation capacity to meet megawatt loads from medium- and heavy-duty EV trucks and buses, enabling managed charging, storage, and corridor fast charging.

Key Points

A utility plan to upgrade feeders and substations for EV fleets, coordinating charging, storage, and load management.

✅ Plans distribution, substation, and transformer upgrades

✅ Supports managed charging and on-site storage

✅ Aligns utility investment with fleet adoption timelines

As more electric buses and trucks enter the market, future fleets will require a lot of electricity for charging and will challenge state power grids over time. While some utilities in California and elsewhere are planning for an increase in power demand, many have yet to do so and need to get started.

This issue is critical, because freight trucks emit more than one-quarter of all vehicle emissions. Recent product developments offer growing opportunities to electrify trucks and buses and slash their emissions (see our recent white paper). And just last week, a group of 15 states plus D.C. announced plans to fully electrify truck sales by 2050. Utilities will need to be ready to power electric fleets.

Electric truck fleets need substantial power
Power for trucks and buses is generally more of an issue than for cars because trucks typically have larger batteries and because trucks and buses are often parts of fleets with many vehicles that charge at the same location. For example, a Tesla Model 3 battery stores 54-75 kWh; a Proterra transit bus battery stores 220-660 kWh. In Amsterdam, a 100-bus transit fleet is powered by a set of slow and fast chargers that together have a peak load of 13 MW (megawatts). This is equivalent to the power used by a typical large factory. And they are thinking of expanding the fleet to 250 buses.

California utilities are finding that grid capacity is often adequate in the short term, but that upgrade needs likely will grow in the medium term.
Many other fleets also will need a lot of "juice." For example, a rough estimate of the power needed to serve a fleet of 200 delivery vans at an Amazon fulfillment center is about 4 MW. And for electric 18-wheelers, chargers may need up to 2 MW of power each; a recent proposal calls for charging stations every 100 miles along the U.S. West Coast’s I-5 corridor, highlighting concerns about EVs and the grid as each site targets a peak load of 23.5 MW.

Utilities need distribution planning
These examples show the need for more power at a given site than most utilities can provide without planning and investment. Meeting these needs often will require changes to primary and secondary power distribution systems (feeders that deliver power to distribution transformers and to end customers) and substation upgrades. For large loads, a new substation may be needed. A paper recently released by the California Electric Transportation Coalition estimates that for loads over 5 MW, distribution system and substation upgrades will be needed most of the time. According to the paper, typical utility costs are $1 million to $9 million for substation upgrades, $150,000 to $6 million for primary distribution upgrades, and $5,000 to $100,000 for secondary distribution upgrades. Similarly, Black and Veatch, in a paper on Electric Fleets, also provides some general guidance, shown in the table below, while recognizing that each site is unique.

California policy pushes utilities toward planning
In California, state agencies and a statewide effort called CALSTART have been funding demonstration projects and vehicle and charger purchases for several years to support grid stability as electrification ramps up. The California Air Resources Board voted in June to phase in zero-emission requirements for truck sales, mandating that, beginning in 2024, manufacturers must increase their zero-emission truck sales to 30-50 percent by 2030 and 40-75 percent by 2035. By 2035, more than 300,000 trucks will be zero-emission vehicles.

California utilities operate programs that work with fleet owners to install the necessary infrastructure for electric vehicle fleets. For example, Southern California Edison operates the Charge Ready Transport program for medium- and heavy-duty fleets. Normally, when customers request new or upgraded service from the utility, there are fees associated with the new upgrade. With Charge Ready, the utility generally pays these costs, and it will sometimes pay half the cost of chargers; the customer is responsible for the other half and for charger installation costs. Sites with at least two electric vehicles are eligible, but program managers report that at least five vehicles are often needed for the economics to make sense for the utility.

One way to do this is to develop and implement a phased plan, with some components sized for future planned growth and other components added as needed. Southern California Edison, for example, has 24 commitments so far, and has a five-year goal of 870 sites, with an average of 10 chargers per site. The utility notes that one charger usually can serve several vehicles and that cycling of charging, some storage, and other load management techniques through better grid coordination can reduce capacity needs (a nominal 10 MW load often can be reduced below 5 MW).

Through this program, utility representatives are regularly talking with fleet operators, and they can use these discussions to help identify needed upgrades to the utility grid. For example, California transit agencies are doing the planning to meet a California Air Resources Board mandate for 100 percent electric or fuel cell buses by 2040; utilities are talking with the agencies and their consultants as part of this process. California utilities are finding that grid capacity is often adequate in the short term, but that upgrade needs likely will grow in the medium term (seven to 10 years out). They can manage grid needs with good planning (school buses generally can be charged overnight and don’t need fast chargers), load management techniques and some energy storage to address peak needs.

Customer conversations drive planning elsewhere
We also spoke with a northeastern utility (wishing to be unnamed) that has been talking with customers about many issues, including fleets. It has used these discussions to identify a few areas where grid upgrades might be needed if fleets electrify. It is factoring these findings into a broader grid-planning effort underway that is driven by multiple needs, including fleets. Even within an integrated planning effort, this utility is struggling with the question of when to take action to prepare the electric system for fleet electrification: Should it act on state or federal policy? Should it act when the specific customer request is submitted, or is there something in between? Recognizing that any option has scheduling and cost allocation implications, it notes that there are no easy answers.

Many utilities need to start paying attention
As part of our research, we also talked with several other utilities and found that they have not yet looked at how fleets might relate to grid planning. However, several of these companies are developing plans to look into these issues in the next year. We also talked with a major truck manufacturer, also wishing to remain unnamed, that views grid limitations as a key obstacle to truck electrification. 

Based on these cases, it appears that fleet electrification can have a substantial impact on electric grids and that, while these impacts are small at present, they likely will grow over time. Fleet owners, electric utilities, and utility regulators need to start planning for these impacts now, so that grid improvements can be made steadily as electric fleets grow. Fleet and grid planning should happen in parallel, so that grid upgrades do not happen sooner or later than needed but are in place when needed, including the move toward a much bigger grid as EV adoption accelerates. These grid impacts can be managed and planned for, but the time to begin this planning is now.

Canada Distributed Energy faces disruption as solar, smart grids, microgrids, and storage scale utility-scale renewables, challenging centralized utilities and accelerating decarbonization, grid modernization, and distributed generation across provinces like Alberta.

Key Points

Canada Distributed Energy shifts from centralized grids to local solar, wind, and storage for reliable low-carbon power.

✅ Morgan Solar and Enbridge launch Alberta Solar One, 13.7 MW.

✅ Optical films boost panel efficiency, lowering cost per watt.

✅ Strong utilities slow adoption of microgrids and smart grids.

By Nick Waddell

Disruption is coming to electricity generation but Canada has become a laggard when it comes to not just adoption of alternative energy sources but in moving to a more distributed model of electricity generation. That’s according to Mike Andrade, CEO of Morgan Solar, whose new solar project in conjunction with Enbridge has just come online in Alberta, a province known as a powerhouse for both green and fossil energy in Canada.

“There’s a lot of inertia to Canada’s electrical system and I don’t think that bodes well,” said Andrade, who spoke on BNN Bloomberg on Thursday. 

“Canada is one of the poorest places for uptake of solar, as NEB data on solar demand indicates,” Andrade said, “I believe a lot of it has to do with the fact that we have strong provincial utilities that have their mandates and their chosen technologies.”

Alberta Solar One, a 13.7 MW power facility near Lethbridge, Alberta, had its unveiling this week amid red-hot solar growth in Alberta that shows no sign of slowing. It’s a 36,500-panel farm constructed by Enbridge in a quick six-month turnaround as part of the power company’s pledge to become a carbon-free generator by 2050. Along with solar, Enbridge has made big investments in offshore and onshore wind farms in the United States, while also producing so-called green hydrogen at an Ontario plant.

Private company Morgan Solar considers the Alberta Solar One project as the first utility-scale validation of its technology, which uses optical films to redirect light onto photovoltaic cells to further power production. 

“We use an advanced modelling system and a variety of tools to design very simple optical systems that can be easily inserted into a panel,” Andrade said. “They cost less and bring down the cost per watt. It captures light that would otherwise miss the cells and so you get more power per cell area than any other commercial technology at this point.”

Like renewables in general, solar energy has been thrust into the spotlight as governments worldwide aim to make good on their climate change and emissions pledges, with analyses showing zero-emissions electricity by 2035 is possible in Canada, and convert power generation from fossil fuels to alternative sources. 

The market has paid attention, too, driving up values on renewable energy stocks across the board, including solar stocks, as provinces like Alberta explore selling renewable energy into broader markets. Last year, the Invesco Solar ETF, which tracks the MAC Global Solar Energy Index, soared 234 per cent, while Canadian companies with solar assets like Algonquin Power and Northland Power have been winners over the past few years.

Canadian cleantech companies involved in the solar power sector have also fared well, with names like UGE International (UGE International Stock Quote, Chart, News, Analyst. Financials TSXV:UGE), Aurora Solar and 5N Plus (5N Plus Stock Quote, Chart, News, Analysts, Financials TSX:VNP) having attracted investor attention of late.

Currently, part of the push in alternative energy involves the move from centralized to a more distributed picture of power generation, where solar panels, wind turbines and small modular nuclear reactors can operate close to or within sources of consumption like cities.

But Andrade says Canada has a lot of catching up to do on that front, especially as its current system seems devoted to maintaining the precedence of large, centralized power production — along with the utility companies that generate it.

“Canada is going to be left with this big, old fashioned hub and spoke model, and that’s increasingly going to be out-competed by a distributed grid, call them smart grids or micro grids,” Andrade said.

“That’s the future that solar is going to drive along with storage, and I personally don’t think Canada is prepared for it, not because we can’t do it but because regulatory and incumbency is holding us back from doing that,” he said.

“We pay our utilities, saying, ‘You invest capital and we’ll give you a fixed return on capital.’ Well, guess what? You’re going to get large, centralized capital projects which are going to get big central generation hub and spoke distribution,” Andrade said.

Ahead of the Canadian federal government’s tabling next week of its first budget in two years, many in the energy sector will be taking notes on the Liberal government’s investments in the so-called green recovery after the economic downturn, with renewable energy proponents hoping for further support, noting Alberta’s renewable energy surge could power thousands of jobs, to shift Canada’s resource sector away from fossil fuels.

By comparison, President Biden in the US recently unveiled his $2-billion infrastructure plan which put precedence on greening the country’s power grid, encouraging the adoption of electric vehicles and supporting renewable resource development, and Canadian studies suggest 2035 zero-emission power is practical and profitable as well across the national grid. 

On disruption in power generation, Andrade said there are parallels to be drawn from information technology, which has historically made a point of discarded outdated models along the way.

“I was at IBM, and they had the mainframe business and that got blown up. I also worked with Nortel and Celestica and they got blown up —and it wasn’t due to having better central hub and spoke systems. They got beat up by this distributed system,” Andrade said. 

“The same thing is going to happen here and the disruption is coming in electricity generation as well,” he said.

Electric vehicles may cost more upfront but often save money long-term. A new MIT study shows the total cost of EV ownership is lower than gas cars when factoring in fuel, maintenance, and emissions.

Total cost of EV ownership is the focus of new MIT research showing electric vehicles offer both financial and environmental benefits over time.

✅ Electric vehicles cost more upfront but save money over their lifetime through lower fuel and maintenance costs

✅ MIT study confirms EVs have lower emissions and total ownership costs than most gas-powered cars

✅ New interactive tool helps consumers compare climate and cost impacts of EVs, hybrids, and traditional vehicles

Electric vehicles are better for the climate than gas‑powered cars, but many Americans are still reluctant to buy them. One reason: The larger upfront cost.

New data published Thursday shows that despite the higher sticker price, electric cars may actually save drivers money in the long-run.

To reach this conclusion, a team at the Massachusetts Institute of Technology calculated both the carbon dioxide emissions and full lifetime cost — including purchase price, maintenance and fuel — for nearly every new car model on the market.

They found electric cars were easily more climate friendly than gas-burning ones. Over a lifetime, they were often cheaper, too.

Jessika Trancik, an associate professor of energy studies at M.I.T. who led the research, said she hoped the data would “help people learn about how those upfront costs are spread over the lifetime of the car.”

For electric cars, lower maintenance costs and the lower costs of charging compared with gasoline prices tend to offset the higher upfront price over time. (Battery-electric engines have fewer moving parts that can break compared with gas-powered engines and they don’t require oil changes. Electric vehicles also use regenerative braking, which reduces wear and tear.)

As EV adoption continues to boom, more consumers are realizing the long-term savings and climate benefits. Ontario’s investment in EV charging stations reflects how infrastructure is beginning to catch up with demand. Despite regional energy pricing differences, EV charging costs remain lower than gasoline in nearly every U.S. city.

The cars are greener over time, too, despite the more emissions-intensive battery manufacturing process. Dr. Trancik estimates that an electric vehicle’s production emissions would be offset in anywhere from six to 18 months, depending on how clean the energy grid is where the car is charging.

In some areas, EVs are even being used to power homes, enhancing their value as a sustainable investment. Recent EPA rules aim to boost EV sales, further signaling government support. California leads the nation in EV charging infrastructure, setting a model for nationwide adoption.

The new data showed hybrid cars, which run on a combination of fuel and battery power, and can sometimes be plugged in, had more mixed results for both emissions and costs. Some hybrids were cheaper and spewed less planet-warming carbon dioxide than regular cars, but others were in the same emissions and cost range as gas-only vehicles.

Traditional gas-burning cars were usually the least climate friendly option, though long-term costs and emissions spanned a wide range. Compact cars were usually cheaper and more efficient, while gas-powered SUVs and luxury sedans landed on the opposite end of the spectrum.

Dr. Trancik’s team released the data in an interactive online tool to help people quantify the true costs of their car-buying decisions — both for the planet and their budget. The new estimates update a study published in 2016 and add to a growing body of research underscoring the potential lifetime savings of electric cars.

Take the Tesla Model 3, the most popular electric car in the United States. The M.I.T. team estimated the lifetime cost of the most basic model as comparable to a Nissan Altima that sells for $11,000 less upfront. (That’s even though Tesla’s federal tax incentive for electric vehicles has ended.)

Toyota’s Hybrid RAV4 S.U.V. also ends up cheaper in the long run than a similar traditional RAV4, a national bestseller, despite a higher retail price.

Hawaii, Alaska and parts of New England have some of the highest average electricity costs, while parts of the Midwest, West and South tend to have lower rates. Gas prices are lower along the Gulf Coast and higher in California. But an analysis from the Union of Concerned Scientists still found that charging a vehicle was more cost effective than filling up at the pump across 50 major American cities. “We saw potential savings everywhere,” said David Reichmuth, a senior engineer for the group’s Clean Transportation Program.

Still, the upfront cost of an electric vehicle continues to be a barrier for many would-be owners.

The federal government offers a tax credit for some new electric vehicle purchases, but that does nothing to reduce the initial purchase price and does not apply to used cars. That means it disproportionately benefits wealthier Americans. Some states, like California, offer additional incentives. President-elect Joseph R. Biden Jr. has pledged to offer rebates that help consumers swap inefficient, old cars for cleaner new ones, and to create 500,000 more electric vehicle charging stations, too.

EV sales projections for 2024 suggest continued acceleration, especially as costs fall and policy support expands. Chris Gearhart, director of the Center for Integrated Mobility Sciences at the National Renewable Energy Laboratory, said electric cars will become more price competitive in coming years as battery prices drop. At the same time, new technologies to reduce exhaust emissions are making traditional cars more expensive. “With that trajectory, you can imagine that even immediately at the purchase price level, certain smaller sedans could reach purchase price parity in the next couple of years,” Dr. Gearhart said.

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.
