The dream of a solar-powered home energized Rick Mielbrecht.

"Until I saw the price tag," he said. The retired San Joaquin Delta College instructor figured he would be dead by the time he saved enough on his utility bill to offset the $30,000 cost.

But there may be another way.

Mielbrecht signed on with a startup company that says it will manufacture solar panels and loan them to customers, who will buy their energy from the company at a fixed rate for up to 25 years. Some see this as a way to dodge future hikes in utility rates.

The Delaware-based company, Citizenre, says it is a way to make solar power mainstream as California strives to reduce its greenhouse gas emissions.

Existing solar providers, such as Stockton-based BTA Solar, say plenty of people are willing to buy solar units outright, adding that companies are coming from out of the area to court prospective buyers. Those who do invest in the purchase of solar panels can make the cost less colossal. Cash incentives can cover about 25 percent of purchased solar panels, and federal tax credits also are available.

Still, the idea of relatively little money down - Citizenre requires a $500 security deposit - has prompted about 24,000 people across the nation to sign up for renting solar panels, including nearly a dozen Stocktonians who attended a meeting organized by Mielbrecht.

Citizenre has its critics, who point out that the company has not actually built any of the solar equipment that it promises to one day install on residential rooftops. It has not even decided where its manufacturing facility will be located. This leaves other solar providers skeptical whether Citizenre can deliver.

Jeffrey Wolfe, chief executive officer of national solar firm GroSolar, earlier this year said Citizenre is "not going to be able to stand up to their promises."

Solar power harvests energy from the sun and converts it for use in the home. This can reduce global warming, since much of the state's conventional energy comes from the burning of fossil fuels.

Power plants emit gases that scientists say are contributing to climate change, future consequences of which include rising sea levels, more intense floods and droughts, and the demise of some animal species. Homes with permanent solar systems are more desirable to potential buyers than homes without, said Terri Steele of the California Center for Sustainable Energy.

Citizenre officials said those who can afford to buy solar panels should go ahead and do so. "Our goal is just to have the solar out there," company representative Mike Hackley said. "This is a new option that we offer."

Feds "changing goalposts" with 2035 net-zero electricity grid target: Sask. premier

Canada Clean Electricity Regulations outline a 2035 net-zero grid target, driving decarbonization via wind, solar, hydro, SMRs, carbon capture, and efficiency, balancing reliability, affordability, and federal-provincial collaboration while phasing out coal and limiting fossil-fuel generation.

 

Key Points

Federal rules to cap CO2 from power plants and deliver a reliable, affordable net-zero grid by 2035.

✅ Applies to fossil-fired units; standards effective by Jan 1, 2035.

✅ Promotes wind, solar, hydro, SMRs, carbon capture, and efficiency.

✅ Balances reliability, affordability, and emissions cuts; ongoing consultation.

 

Saskatchewan’s premier said the federal government is “changing goalposts” with its proposed target for a net-zero electricity grid.

“We were looking at a net-zero plan in Saskatchewan and across Canada by the year 2050. That’s now been bumped to 2035. Well there are provinces that quite frankly aren’t going to achieve those types of targets by 2035,” Premier Scott Moe said Wednesday.

Ottawa proposed the Clean Electricity Regulations – formerly the Clean Electricity Standard – as part of its target for Canada to transition to net-zero emissions by 2050.

The regulations would help the country progress towards an updated proposed goal of a net-zero electricity grid by 2035.

“They’re un-consulted, notional targets that are put forward by the federal government without working with industries, provinces or anyone that’s generating electricity,” Moe said.

The Government of Canada was seeking feedback from stakeholders on the plan’s regulatory framework document earlier this year, up until August 2022.

“The clean electricity standard is something that’s still being consulted on and we certainly heard the views of Saskatchewan – not just Saskatchewan, many other provinces – and I think that’s something that’s being reflected on,” Jonathan Wilkinson, Canada’s minister of natural resources, said during an event near Regina Wednesday.

“We also recognize that the federal government has a role to play in helping provinces to make the kinds of changes that would need to be made in order to actually achieve a clean grid,” Wilkinson added.

The information received during the consultation will help inform the development of the proposed regulations, which are expected to be released before the end of the year, according to the federal government.


NET-ZERO ELECTRICITY GRID
The federal government said its Clean Electricity Regulations (CER) is part of a suite of measures, as the country moves towards a broad “decarbonization” of the economy, with Alberta's clean electricity path illustrating provincial approaches as well.

Net-zero emissions would mean Canada’s economy would either emit no greenhouse gas emissions or offset its emissions.

The plan encourages energy efficiency, abatement and non-emitting generation technologies such as carbon capture and storage and electricity generation options such as solar, wind, geothermal, small modular nuclear reactors (SMRs) and hydro, among others.

The government suggests consumer costs could be lowered by using some of these energy efficiency techniques, alongside demand management and a shift to lower-cost wind and solar power, echoing initiatives like the SaskPower 10% rebate aimed at affordability.

The CER focuses on three principles, each tied to affordability debates like the SaskPower rate hike in Saskatchewan:

 Maximize greenhouse gas reductions to achieve the 2035 target
 Ensure a reliable electrical grid to support Canadians and the economy
 Maintain electrical affordability

“Achieving a net-zero electricity supply is key to reaching Canada’s climate targets in two ways,” the government said in its proposed regulations.

“First, it will reduce [greenhouse gas] emissions from the production of electricity. Second, using clean electricity instead of fossil fuels in vehicles, heating and industry will reduce emissions from those sectors too.

The regulations would regulate carbon dioxide emissions from electricity generating units that combust any amount of fossil fuel, have a capacity above a small megawatt threshold and sell electricity onto a regulated electricity system.

New rules would also be implemented for the development of new electricity generation units firing fossil fuels in or after 2025 and existing units. All units would be subject to emission standards by Jan. 1, 2035, at the latest.

The federal government launched consultations on the proposed regulations in March 2022.

Canada also has a 2030 emissions reduction plan that works towards meeting its Paris Agreement target to reduce emissions by 40-45 per cent from 2005 levels by 2030. This plan includes regulations to phase out coal-fired electricity by 2030.


COLLABORATION
The province recently introduced the Saskatchewan First Act, in an attempt to confirm its own jurisdiction and sovereignty when it comes to natural resources.

The act would amend Saskatchewan’s constitution to exert exclusive legislative jurisdiction under the Constitution of Canada.

The province is seeking jurisdiction over the exploration of non-renewable resources, the development, conservation and management of non-renewable natural and forestry resources, and the operation of sites and facilities for the generation and production of electrical energy.

While the federal government and Saskatchewan have come head-to-head publicly over several policy concerns in the past year, both sides remain open to collaborating on issues surrounding natural resources.

“We do have provincial jurisdiction in the development of these natural resources. We’d like to work collaboratively with the federal government on developing some of the most sustainable potash, uranium, agri-food products in the world,” Moe said.

Minister Wilkinson noted that while both the federal and provincial governments aim to respect each other’s jurisdiction, there is often some overlap, particularly in the case of environmental and economic policies, with Alberta's electricity sector changes underscoring those tensions as well.

“My view is we should endeavour to try to figure out ways that we can work together, and to ensure that we’re actually making progress for Saskatchewanians and for Canadians,” Wilkinson said.

“I think that Canadians expect us to try to figure out ways to work together, and where there are some disputes that can’t get resolved, ultimately the Supreme Court will decide on the issue of jurisdiction as they did in the case on the price on pollution.”

Moe said Saskatchewan is always open to working with the federal government, but not at the expense of its “provincial, constitutional autonomy.”

Huge offshore wind turbine that can power 18,000 homes

Siemens Gamesa SG 14-222 DD advances offshore wind with a 14 MW direct-drive turbine, 108 m blades, a 222 m rotor, optional 15 MW boost, powering about 18,000 homes; prototype 2021, commercial launch 2024.

 

Key Points

A 14 MW offshore wind turbine with 108 m blades and a 222 m rotor, upgradable to 15 MW, targeting commercial use in 2024.

✅ 14 MW direct-drive, upgradable to 15 MW

✅ 108 m blades, 222 m rotor diameter

✅ Powers about 18,000 European homes annually

 

Siemens Gamesa Renewable Energy (SGRE) has released details of a 14-megawatt (MW) offshore wind turbine, as offshore green hydrogen production gains attention, in the latest example of how technology in the sector is increasing in scale.

With 108-meter-long blades and a rotor diameter of 222 meters, the dimensions of the SG 14-222 DD turbine are significant.

In a statement Tuesday, SGRE said that one turbine would be able to power roughly 18,000 average European households annually, while its capacity can also be boosted to 15 MW if needed. A prototype of the turbine is set to be ready by 2021, and it’s expected to be commercially available in 2024, as forecasts suggest a $1 trillion business this decade.

As technology has developed over the last few years, the size of wind turbines has increased, and renewables are set to shatter records globally.

Last December, for example, Dutch utility Eneco started to purchase power produced by the prototype of GE Renewable Energy’s Haliade-X 12 MW wind turbine. That turbine has a capacity of 12 MW, a height of 260 meters and a blade length of 107 meters.

The announcement of Siemens Gamesa’s new turbine plans comes against the backdrop of the coronavirus pandemic, which is impacting renewable energy companies around the world, even as wind power sees growth despite Covid-19 in many markets.

Earlier this month, the European company said Covid-19 had a “direct negative impact” of 56 million euros ($61 million) on its profitability between January and March, amid factory closures in Spain and supply chain disruptions. This, it added, was equivalent to 2.5% of revenues during the quarter.

The pandemic has, in some parts of the world, altered the sources used to power society. At the end of April, for instance, it was announced that a new record had been set for coal-free electricity generation in Great Britain, where UK offshore wind growth has accelerated, with a combination of factors — including coronavirus-related lockdown measures — playing a role.

On Tuesday, the CEO of another major wind turbine manufacturer, Danish firm Vestas, sought to emphasize the importance of renewable energy in the years and months ahead, and the lessons the U.S. can learn from the U.K. on wind deployment.

“I think we have actually, throughout this crisis, also shown to all society that renewables can be trusted,” Henrik Andersen said during an interview on CNBC’s Street Signs.

“But we both know ... that that transformation of energy sources is not going to happen overnight, it’s not going to happen from a quarter to a quarter, it’s going to happen by consistently planning year in, year out.”

NTPC bags order to supply 300 MW electricity to Bangladesh

NTPC Bangladesh Power Supply Tender sees NVVN win 300 MW, long-term cross-border electricity trade to BPDB, enabled by 500 MW HVDC interconnection; rivals included Adani, PTC, and Sembcorp in the competitive bidding process.

 

Key Points

It is NTPC's NVVN win to supply 300 MW to Bangladesh's BPDB for 15 years via a 500 MW HVDC link.

✅ NVVN selected as L1 for short and long-term supply

✅ 300 MW to BPDB; delivery via India-Bangladesh HVDC link

✅ Competing bidders: Adani, PTC, Sembcorp

 

NTPC, India’s biggest electricity producer in a nation that is now the third-largest electricity producer globally, on Tuesday said it has won a tender to supply 300 megawatts (MW) of electricity to Bangladesh for 15 years.

Bangladesh Power Development Board (BPDP), in a market where Bangladesh's nuclear power is expanding with IAEA assistance, had invited tenders for supply of 500 MW power from India for short term (1 June, 2018 to 31 December, 2019) and long term (1 January, 2020 to 31 May, 2033). NTPC Vidyut Vyapar Nigam (NVVN), Adani Group, PTC and Singapore-bases Sembcorp submitted bids by the scheduled date of 11 January.

Financial bid was opened on 11 February, the company said in a statement, amid rising electricity prices domestically. “NVVN, wholly-owned subsidiary of NTPC Limited, emerged as successful bidder (L1), both in short term and long term for 300 MW power,” it said.

Without giving details of the rate at which power will be supplied, NTPC said supply of electricity is likely to commence from June 2018 after commissioning of 500 MW HVDC inter-connection project between India and Bangladesh, and as the government advances nuclear power initiatives to bolster capacity in the sector. India currently exports approximately 600 MW electricity to Bangladesh even as authorities weigh coal rationing measures to meet surging demand domestically.

NY Governor Cuomo Announces Green New Deal Included in 2019 Executive Budget

New York Green New Deal accelerates clean energy and climate action, targeting carbon neutrality with renewable energy, offshore wind, solar, energy storage, and green jobs while advancing environmental justice and economy-wide decarbonization.

 

Key Points

New York's plan for 100% clean power by 2040 and 70% renewables by 2030, with a just transition and green jobs.

✅ 100% carbon-free electricity by 2040; 70% renewables by 2030

✅ 9,000 MW offshore wind and 3,000 MW energy storage targets

✅ Just transition focuses on jobs, equity, and affordability

 

New York Governor Andrew M. Cuomo announced the Green New Deal, a nation-leading clean energy and jobs agenda that will aggressively put New York State on a path to net-zero electricity and economy-wide carbon neutrality, is included in the 2019 Executive Budget. The landmark plan provides for a just transition to clean energy that spurs growth of the green economy and prioritizes the needs of low- to moderate-income New Yorkers.

"Climate change is a reality, and the consequences of delay are a matter of life and death. We know what we must do. Now we have to have the vision, the courage, and the competence to get it done," Governor Cuomo said. "While the federal government shamefully ignores the reality of climate change and fails to take meaningful action, we are launching the first-in-the-nation Green New Deal to seize the potential of the clean energy economy, set nation's most ambitious goal for carbon-free power, and ultimately eliminate our entire carbon footprint."

During Governor Cuomo's first two terms, New York banned fracking of natural gas, committed to phasing out coal power by 2020, mandated 50 percent renewable power by 2030, and established the U.S. Climate Alliance to uphold the Paris Agreement, reflecting the view that decarbonization is irreversible under a clean energy economy. Under the Reforming the Energy Vision agenda, New York has held the largest renewable energy procurements in U.S. history, solar has increased nearly 1,500 percent, and offshore wind is poised to transform the State's electricity supply to be cleaner and more sustainable. Through Governor Cuomo's Green New Deal, New York will take the bold next steps to secure a clean energy future that protects the environment for generations to come while growing the clean energy economy.

 

100 Percent Clean Power by 2040 Coupled with New Nation-leading Renewable Energy Mandates

The Green New Deal will statutorily mandate New York's power be 100 percent carbon-free by 2040, the most aggressive goal in the United States and five years ahead of a target recently adopted by California state policymakers. The cornerstone of this new mandate is a significant increase of New York's successful Clean Energy Standard mandate from 50 percent to 70 percent renewable electricity by 2030. This globally unprecedented ramp-up of renewable energy will include:

  • Quadrupling New York's offshore wind target to 9,000 megawatts by 2035, up from 2,400 megawatts by 2030
  • Doubling distributed solar deployment to 6,000 megawatts by 2025, up from 3,000 megawatts by 2023
  • More than doubling new large-scale land-based wind and solar resources through the Clean Energy Standard
  • Maximizing the contributions and potential of New York's existing renewable resources
  • Deploying 3,000 megawatts of energy storage by 2030, up from 1,500 megawatts by 2025
  • Develop an Implementation Plan to Make New York Carbon Neutral

The Green New Deal will create the State's first statutory Climate Action Council, comprised of the heads of relevant State agencies and other workforce, environmental justice, and clean energy experts to develop a comprehensive plan to make New York carbon neutral by significantly and cost-effectively reducing emissions from all major sources, including electricity, transportation, buildings, industry, commercial activity, and agriculture. The Climate Action Council will consider a range of possible options, including the feasibility of working with the U.S. Climate Alliance to create a new multistate emissions reduction program that covers all sectors of the economy, including transportation and industry, and exploring ways to leverage the successful Regional Greenhouse Gas Initiative to drive transformational investment in the clean energy economy and support a just transition.

At the national level, a historic climate deal is reshaping incentives and standards for clean energy deployment across the country.

The Green New Deal will also include an ambitious strategy to move New York's statewide building stock to carbon neutrality. The agenda includes:

Advancing legislative changes to strengthen building energy codes and establish appliance efficiency standards

Directing State agencies to ensure that their facilities uphold the strongest energy efficiency and sustainability standards

Developing a Net Zero Roadmap to chart a course to statewide carbon neutrality in buildings

A Multibillion Dollar Green New Deal Investment in the Clean Tech Economy that will Reduce Greenhouse Gas Emissions

Demonstrating New York's immediate commitment to implementing the nation's most ambitious clean energy agenda and creating high-quality clean energy jobs, Governor Cuomo is announcing $1.5 billion in competitive awards to support 20 large-scale solar, wind and energy storage projects across upstate New York. These investments will add over 1,650 megawatts of capacity and generate over 3,800,000 megawatt-hours of renewable energy annually - enough to power nearly 550,000 homes and create over 2,600 short and long-term jobs. Combined with the renewable energy projects previously announced under the Clean Energy Standard, New York has now awarded more than $2.9 billion to 46 projects statewide, enough to power over one million households.

The Green New Deal also includes new investments to jumpstart New York's offshore wind energy industry and support the State's world-leading target of 9,000 megawatts by 2035. New York will invest up to $200 million in port infrastructure to match private sector investment in regional development of offshore wind. This multi-location investment represents the nation's largest infrastructure commitment to offshore wind and solidifies New York's position as the hub of the burgeoning U.S. offshore wind industry.

These new investments build upon a $250 million commitment to electric vehicle infrastructure by the New York Power Authority's EVolve program, $3.5 billion in private investment in distributed solar driven by NYSERDA's NY-Sun program, and NY Green Bank transactions mobilizing nearly $1.75 billion in private capital for clean energy projects.

 

A Just Transition to a Clean Energy Economy

Deliver Climate Justice for Underserved Communities: The Green New Deal will help historically underserved communities prepare for a clean energy future and adapt to climate change by:

Giving communities a seat at the table by codifying the Environmental Justice and Just Transition Working Group into law and incorporating it into the planning process for the Green New Deal's implementation.

Directing the State's low-income energy task force to identify reforms to achieve greater impact of the public energy funds expended each year in order to increase the effect of funds and initiatives that target energy affordability to underserved communities.

Directing each of the State's ten Regional Economic Development Councils to develop an environmental justice strategy for their region.

Finance a Property Tax Compensation Fund to Help Communities Transition to the Clean Energy Economy: Governor Cuomo is introducing legislation to finance the State's $70 million Property Tax Compensation Fund to continue helping communities directly affected by the transition away from dirty and obsolete energy industries and toward the new clean energy economy. Specifically, this funding will protect communities impacted by the retirement of conventional power generation facilities.

Protect Labor Rights: To ensure creation of high-quality clean energy jobs, large-scale renewable energy projects supported by the Green New Deal will require prevailing wage, and the State's offshore wind projects will be supported by a requirement for a Project Labor Agreement.

Develop the Clean Tech Workforce: To prepare New York's workforce for the transition, New York State will take new steps to support workforce development, including establishing a New York State Advisory Council on Offshore Wind Economic and Workforce Development, as well as investing in an offshore wind training center that will provide New Yorkers with the skills and safety training required to construct this clean energy technology in New York.   

Richard Kauffman, Chairman of Energy and Finance for New York, said, "Governor Cuomo's Green New Deal will advance New York State further into the clean energy future, and we won't let the Trump Administration push us backwards. Governor Cuomo's new commitments ensure New York is the undisputed national clean energy and climate leader, and we will continue to build upon the foundations of the REV agenda to achieve a sustainable economy and healthy environment for generations of New Yorkers to come."

Alicia Barton, President and CEO, NYSERDA, said, "Climate scientists have made frighteningly clear that averting the worst effects of climate change will require bold action, not incremental steps, and Governor Cuomo's Green New Deal boldly goes where no others have before. His unwavering climate agenda includes the most aggressive clean energy target in U.S. history, the largest commitments to renewable energy and to offshore wind in the nation, a massive mobilization of clean energy jobs and an unprecedented investment in offshore wind port infrastructure. Together these actions make New York the clear national leader in the fight against climate change, and will show the world that New York can and will achieve a clean energy future for the sake of future generations."

DEC Commissioner Basil Seggos said, "The threat of climate change calls for bold action like Governor Cuomo's comprehensive agenda to make New York State carbon neutral. The Green New Deal ensures New York is continuing our nation-leading efforts to capitalize on the economic potential of the clean energy economy, while making sure those most vulnerable to climate change are benefitting from the state's efforts and investments. I look forward to working with my agency and authority partners on the Climate Action Council to develop and implement meaningful solutions to reduce greenhouse gas emissions from all sectors of our economy."  

John B. Rhodes, CEO, Department of Public Service, said, "With this nation-leading Green New Deal, Governor Cuomo puts New York on the path to fully clean electricity and to carbon neutrality with the strongest renewable energy goals in the nation. This will deliver the energy system that New York needs - cost-effective, reliable, and 100% clean.”

A new material made from carbon nanotubes can generate electricity by scavenging energy from its environment

Carbon Nanotube Solvent Electricity enables wire-free electrochemistry as organic solvents like acetonitrile pull electrons, powering alcohol oxidation and packed bed reactors, energy harvesting, and micro- and nanoscale robots via redox-driven current.

 

Key Points

Solvent-driven electron extraction from carbon nanotube particles generates current for electrochemistry.

✅ 0.7 V per particle via solvent-induced electron flow

✅ Packed bed reactors drive alcohol oxidation without wires

✅ Scalable for micro- and nanoscale robots; energy harvesting

 

MIT engineers have discovered a new way of generating electricity, alongside advances in renewable power at night that broaden what's possible, using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.

The liquid, an organic solvent, draws electrons out of the particles, generating a current, unlike devices based on a cheap thermoelectric material that rely on heat, that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say.

"This mechanism is new, and this way of generating energy is completely new," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. "This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires."

In a new study describing this phenomenon, the researchers showed that they could use this electric current to drive a reaction known as alcohol oxidation—an organic chemical reaction that is important in the chemical industry.

Strano is the senior author of the paper, which appears today in Nature Communications. The lead authors of the study are MIT graduate student Albert Tianxiang Liu and former MIT researcher Yuichiro Kunai. Other authors include former graduate student Anton Cottrill, postdocs Amir Kaplan and Hyunah Kim, graduate student Ge Zhang, and recent MIT graduates Rafid Mollah and Yannick Eatmon.

Unique properties
The new discovery grew out of Strano's research on carbon nanotubes—hollow tubes made of a lattice of carbon atoms, which have unique electrical properties. In 2010, Strano demonstrated, for the first time, that carbon nanotubes can generate "thermopower waves." When a carbon nanotube is coated with layer of fuel, moving pulses of heat, or thermopower waves, travel along the tube, creating an electrical current that exemplifies turning thermal energy into electricity in nanoscale systems.

That work led Strano and his students to uncover a related feature of carbon nanotubes. They found that when part of a nanotube is coated with a Teflon-like polymer, it creates an asymmetry, distinct from conventional thermoelectric materials approaches, that makes it possible for electrons to flow from the coated to the uncoated part of the tube, generating an electrical current. Those electrons can be drawn out by submerging the particles in a solvent that is hungry for electrons.

To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.

When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.

"The solvent takes electrons away, and the system tries to equilibrate by moving electrons," Strano says. "There's no sophisticated battery chemistry inside. It's just a particle and you put it into solvent and it starts generating an electric field."

Particle power
The current version of the particles can generate about 0.7 volts of electricity per particle. In this study, the researchers also showed that they can form arrays of hundreds of particles in a small test tube. This "packed bed" reactor, unlike thin-film waste-heat harvesters for electronics, generates enough energy to power a chemical reaction called an alcohol oxidation, in which an alcohol is converted to an aldehyde or a ketone. Usually, this reaction is not performed using electrochemistry because it would require too much external current.

"Because the packed bed reactor is compact, it has more flexibility in terms of applications than a large electrochemical reactor," Zhang says. "The particles can be made very small, and they don't require any external wires in order to drive the electrochemical reaction."

In future work, Strano hopes to use this kind of energy generation to build polymers using only carbon dioxide as a starting material. In a related project, he has already created polymers that can regenerate themselves using carbon dioxide as a building material, in a process powered by solar energy and informed by devices that generate electricity at night as a complement. This work is inspired by carbon fixation, the set of chemical reactions that plants use to build sugars from carbon dioxide, using energy from the sun.

In the longer term, this approach could also be used to power micro- or nanoscale robots. Strano's lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors. The idea of being able to scavenge energy from the environment, including approaches that produce electricity 'out of thin air' in ambient conditions, to power these kinds of robots is appealing, he says.

"It means you don't have to put the energy storage on board," he says. "What we like about this mechanism is that you can take the energy, at least in part, from the environment."

Warning: Manitoba Hydro can't service new 'energy intensive' customers

Manitoba Hydro capacity constraints challenge clean energy growth as industrial demand, hydrogen projects, EV batteries, and electrification strain the grid; limited surplus, renewables, storage, and transmission bottlenecks hinder new high-load connections.

 

Key Points

Limited surplus power blocks new energy-intensive loads until added generation and transmission expand Manitoba's grid.

✅ No firm commitments for new energy-intensive industrial customers

✅ Single large load could consume remaining surplus capacity

✅ New renewables need transmission; gas, nuclear face trade-offs

 

Manitoba Hydro lacks the capacity to provide electricity to any new "energy intensive" industrial customers, the Crown corporation warns in a confidential briefing note that undercuts the idea this province can lure large businesses with an ample supply of clean, green energy, as the need for new power generation looms for the utility.

On July 28, provincial economic development officials unveiled an "energy roadmap" that said Manitoba Hydro must double or triple its generating capacity, as electrical demand could double over the next two decades in order to meet industrial and consumer demand for electricity produced without burning fossil fuels.

Those officials said 18 potential new customers with high energy needs were looking at setting up operations in Manitoba — and warned the province must be careful to choose businesses that provide the greatest economic benefit as well as the lowest environmental impact.

In a briefing note dated Sept. 13, obtained by CBC News, Manitoba Hydro warns it doesn't have enough excess power to hook up any of these new heavy electricity-using customers to the provincial power grid.

There are actually 57 proposals to use large volumes of electricity, Hydro says in the note, including eight projects already in the detailed study phase and nine where the proponents are working on construction agreements.

"Manitoba Hydro is unable to offer firm commitments to prospective customers that may align with Manitoba's energy roadmap and/or provincial economic development objectives," Hydro warns in the note, explaining it is legally obliged to serve all existing customers who need more electricity.

"As such, Manitoba Hydro cannot reserve electric supply for particular projects."

Hydro says in the note its "near-term surplus electricity supply" is so limited amid a Western Canada drought that "a single energy-intensive connection may consume all remaining electrical capacity."

Adding more electrical generating capacity won't be easy, even with new turbine investments underway, and will not happen in time to meet demands from customers looking to set up shop in the province, Hydro warns.

The Crown corporation goes on to say it's grappling with numerous requests from existing and prospective energy-intensive customers, mainly for producing hydrogen, manufacturing electric vehicle batteries and switching from fossil fuels to electricity, such as to use electricity for heat in buildings.

In a statement, Hydro said it wants to ensure Manitobans know the corporation is not running out of power — just the ability to meet the needs of large new customers, and continues to provide clean energy to neighboring provinces today.

"The size of loads looking to come to Manitoba are significantly larger than we typically see, and until additional supply is available, that limits our ability to connect them," Hydro spokesperson Bruce Owen said in a statement.

Adding wind power or battery storage, for example, would require the construction of more transmission lines, and deals such as SaskPower's purchase depend on that interprovincial infrastructure as well.

Natural gas plants are relatively inexpensive to build but do not align with efforts to reduce carbon emissions. Nuclear power plants require at least a decade of lead time to build, and tend to generate local opposition.

Hydro has also ruled out building another hydroelectric dam on the Nelson River, where the Conawapa project was put on hold in 2014.
