Officials of Hawaiian Electric Company and Sensus Metering Systems announced a 15-year definitive agreement for mass deployment of Sensus Metering SystemsÂ’ FlexNet wireless smart grid solution.

The decision comes after two years of rigorous field testing of the FlexNet system, where thousands of smart electric meters were tested in a variety of settings, terrains and environments on Oahu.

Subject to Hawaii Public Utilities Commission approval of Hawaiian Electric’s AMI plan, approximately 430,000 residential and commercial electric customers will be transitioned to the Sensus FlexNet smart meters between 2009 and 2015. Just 19 tower network sites throughout Oahu, Maui, and Hawaii Island will provide the advanced, two-way radio frequency (“RF”) network coverage based on Sensus’ industry-leading primary use licensed frequency, which allows for secure, reliable transmissions over the widest possible range.

The FlexNet system provides Hawaiian Electric with two-way communications to SensusÂ’ iCon smart electric meters, which enables on-demand reads, remote connect/disconnect services, notifications of outages and restoration, and remote firmware upgrades. FlexNet also establishes the platform for additional customer and utility system related benefits in the future.

These features will support new pricing and demand-response initiatives to help customers manage their own electricity use by taking advantage of various pricing options, and programs designed to enhance energy conservation efforts.

“We have carefully evaluated the FlexNet AMI system over a series of pilot tests including meter deployment and performance, customer billing and outage management,” said Dr. Karl E. Stahlkopf, Hawaiian Electric Senior Vice President Energy Solutions & Chief Technology Officer. “The results demonstrate that Sensus clearly delivers the technology solution we require for urban and rural coverage, with the power and flexibility for future advanced applications that will benefit our customers and our operations.”

Stahlkopf further noted the deployment of the smart meters is a key action to help achieve the goals of the recently announced Hawaii Clean Energy Initiative agreement between Hawaiian Electric and the State of Hawaii to expand HawaiiÂ’s renewable energy portfolio and move towards a sustainable, clean energy future.

Peter Mainz, Sensus’ Chief Executive Officer, noted that the Hawaiian Electric field test was accomplished amid some challenging areas. “But as a technology leader, Sensus produced reliable results. Therefore, Hawaiian Electric’s decision to select FlexNet for company-wide deployment reaffirms our position as a leader in two-way AMI systems. Our partnership with the utility has also proven valuable in shaping the product and business direction for Sensus.”

Scientists generate 'electricity from thin air.' Humidity could be a boundless source of energy.

Air Humidity Energy Harvesting converts thin air into clean electricity using air-gen devices with nanopores, delivering continuous renewable energy from ambient moisture, as demonstrated by UMass Amherst researchers in Advanced Materials.

 

Key Points

A method using nanoporous air-gen devices to harvest continuous clean electricity from ambient atmospheric moisture.

✅ Nanopores drive charge separation from ambient water molecules

✅ Works across materials: silicon, wood, bacterial films

✅ Predictable, continuous power unlike intermittent solar or wind

 

Sure, we all complain about the humidity on a sweltering summer day. But it turns out that same humidity could be a source of clean, pollution-free energy, aligning with efforts toward cheap, abundant electricity worldwide, a new study shows.

"Air humidity is a vast, sustainable reservoir of energy that, unlike wind and solar power resources, is continuously available," said the study, which was published recently in the journal Advanced Materials.

While humidity harvesting promises constant output, advances like a new fuel cell could help fix renewable energy storage challenges, researchers suggest.

“This is very exciting,” said Xiaomeng Liu, a graduate student at the University of Massachusetts-Amherst, and the paper’s lead author. “We are opening up a wide door for harvesting clean electricity from thin air.”

In fact, researchers say, nearly any material can be turned into a device that continuously harvests electricity from humidity in the air, a concept echoed by raindrop electricity demonstrations in other contexts.

“The air contains an enormous amount of electricity,” said Jun Yao, assistant professor of electrical and computer engineering at the University of Massachusetts-Amherst and the paper’s senior author. “Think of a cloud, which is nothing more than a mass of water droplets. Each of those droplets contains a charge, and when conditions are right, the cloud can produce a lightning bolt – but we don’t know how to reliably capture electricity from lightning.

"What we’ve done is to create a human-built, small-scale cloud that produces electricity for us predictably and continuously so that we can harvest it.”

The heart of the human-made cloud depends on what Yao and his colleagues refer to as an air-powered generator, or the "air-gen" effect, which relates to other atmospheric power concepts like night-sky electricity studies in the field.

In broader renewable systems, flexible resources such as West African hydropower can support variable wind and solar output, complementing atmospheric harvesting concepts as they mature.

The study builds on research from a study published in 2020. That year, scientists said this new technology "could have significant implications for the future of renewable energy, climate change and in the future of medicine." That study indicated that energy was able to be pulled from humidity by material that came from bacteria; related bio-inspired fuel cell design research explores better electricity generation, the new study finds that almost any material, such as silicon or wood, also could be used.

The device mentioned in the study is the size of a fingernail and thinner than a single hair. It is dotted with tiny holes known as nanopores, it was reported. "The holes have a diameter smaller than 100 nanometers, or less than a thousandth of the width of a strand of human hair."

Iran turning thermal power plants to combined cycle to save energy

Iran Combined-Cycle Power Plants drive energy efficiency, cut greenhouse gases, and expand megawatt capacity by converting thermal units; MAPNA-led upgrades boost grid reliability, reduce fuel use, and accelerate electricity generation growth nationwide.

 

Key Points

Upgraded thermal plants that reuse waste heat to boost efficiency, cut emissions, and add capacity to Iran's grid.

✅ 27 thermal plants converted; 160 more viable units identified

✅ Adds 12,600 MW capacity via heat recovery steam generators

✅ Combined-cycle share: 31.2% of 80.509 GW capacity

 

Iran has turned six percent of its thermal power plans into combined cycle plants in order to reduce greenhouse gases and save energy, with potential to lift thermal plants' PLF under rising demand, IRNA reported, quoting an energy official.

According to the MAPNA Group’s Managing Director Abbas Aliabadi, so far 27 thermal power plants have been converted to combined-cycle ones, aligning with Iran’s push to transmit power to Europe as a regional hub.

“The conversion of a thermal power plant to a combined cycle one takes about one to two years, however, it is possible for us to convert all the country’s thermal power plants into combined cycle plants over a five-year period.

Currently, a total of 478 thermal power plants are operating throughout Iran, of which 160 units could be turned into combined cycle plants. In doing so, 12,600 megawatts will be added to the country’s power capacity, supporting ongoing exports such as supplying a large share of Iraq's electricity under existing arrangements.

Related cross-border work includes deals to rehabilitate Iraq's power grid that support future exchanges.

As reported by IRNA on Wednesday, Iran’s Nominal electricity generation capacity has reached 80,509 megawatts (80.509 gigawatts), and it is deepening energy cooperation with Iraq to bolster regional reliability. The country increased its electricity generation capacity by 500 megawatts (MW) compared to the last year (ended on March 20).

Currently, with a total generation capacity of 25,083 MW (31.2 percent) combined cycle power plants account for the biggest share in the country’s total power generation capacity followed by gas power plants generating 29.9 percent, amid global trends where renewables are set to eclipse coal and regional moves such as Israel's coal reduction signal accelerating shifts.

N.S. joins Western Climate Initiative for tech support for emissions plan

Nova Scotia Cap-and-Trade Program joins Western Climate Initiative to leverage emissions trading IT systems, track allowances, and manage compliance, while setting in-province caps, carbon pricing signals, and third-party verified reporting for industrial and fuel suppliers.

 

Key Points

A provincial emissions trading system using WCI services to cap GHGs, track allowances, and enforce verified compliance.

✅ Uses WCI IT system to manage allowances and registry

✅ Initial trading limited to in-province participants

✅ Third-party verification and annual reporting deadlines

 

Nova Scotia is yet to set targets for its new cap and trade regime to reduce greenhouse gases, but the province announced Monday that it has joined the Western Climate Initiative Inc. -- a non-profit corporation formed to provide administrative and technical services to states and provinces with emissions trading programs.

Environment Minister Iain Rankin said joining the initiative would allow the province to use its IT system to manage and track its new cap and trade program.

Rankin said the province can join without trading greenhouse gas emission allowances with other jurisdictions -- California, Quebec, and Ontario are currently linked through the program, with Hydro-Québec's U.S. sales highlighting cross-border dynamics. Nova Scotia currently has no plans to trade outside the province as it works on emissions caps Rankin said will be ready sometime in June.

Nova Scotia is yet to set targets for its new cap and trade regime to reduce greenhouse gases, but the province announced Monday that it has joined the Western Climate Initiative Inc. -- a non-profit corporation formed to provide administrative and technical services to states and provinces with emissions trading programs.

Environment Minister Iain Rankin said joining the initiative would allow the province to use its IT system to manage and track its new cap and trade program.

Rankin said the province can join without trading greenhouse gas emission allowances with other jurisdictions -- California, Quebec, and Ontario are currently linked through the program. Nova Scotia currently has no plans to trade outside the province as it works on emissions caps Rankin said will be ready sometime in June.

"By keeping our system internal it ensures that our greenhouse gas reductions are happening within our province," said Rankin. "But we do have that opportunity (to join) and if there are new entrants or we need more access to credits then that may shift our strategy."

The use of the system will cost Nova Scotia about US$314,000 for 2018-19, with an annual cost in subsequent years of about US$228,000 or more, if the province requests modifications.

"If we were to do something like that internally we would have to build a full database and hire more people, so this was an obvious choice for us," said Rankin.

Nova Scotia has already met the national reduction target of 30 per cent below 2005 levels and says it's on track to have 40 per cent of electricity generation from renewables by 2020, underscoring how cleaning up Canada's electricity supports climate pledges.

Stephen Thomas, energy campaign coordinator for the Ecology Action Centre, called the province's move an "important small step," stressing the importance of using the same administrative rules as the other jurisdictions involved.

But Thomas said Nova Scotia should go further and trade emissions with California, Quebec, and Ontario, and also put a price on carbon by auctioning credits as they do.

Thomas said Nova Scotia's system stands to be volatile because of the smaller number of participants -- about 20 including Nova Scotia Power, Northern Pulp, Lafarge, and large oil and gasoline companies such as ExxonMobil, Imperial and Irving.

"It's very likely to favour Nova Scotia Power as the largest single emitter with the most credits to sell here, and that would change if we had a linked system, at a time when Canada will need more electricity to hit net-zero according to the IEA," Thomas said.

He said it's important to have a linked system and a regional approach in Atlantic Canada, which has more emissions per person and more emissions per GDP than places like Ontario, Quebec and California, and where policies like Newfoundland's rate reduction plan can influence electricity strategy.

"Reducing emissions, because we are so emissions-intensive here, is a little bit cheaper," said Thomas. "So it's possible that Ontario, Quebec and California could pay Nova Scotia to reduce its emissions."

Under its program, Nova Scotia requires industrial facilities generating 50,000 tonnes or more of greenhouse gas emissions per year to report emissions.

Regulations also cover petroleum product suppliers that import or produce 200 litres of fuel or more per year for consumption and natural gas distributors whose products produce at least 10,000 tonnes of greenhouse gas emissions a year.

Companies were to have reported to the Environment Department by May 1 but Rankin said the deadline has been pushed back to June 1, a deadline that was to be followed in subsequent years in any event. Reports must be verified by a third party by Sept. 1 every year.

The Liberal government passed enabling legislation for cap and trade last fall.

As for the upcoming emissions caps, Rankin isn't tipping the province's hand yet, even as B.C.'s 2050 targets face a shortfall in some forecasts.

"Those caps will recognize the investments that have already been made and therefore will be the most cost-effective program that we can put together to meet the federal requirement," he said.

Germany shuts down its last three nuclear power plants

Germany Nuclear Phase-Out ends power generation from reactors, prioritizing energy security, renewables, and emissions goals amid the Ukraine war, natural gas shortages, decommissioning plans, and climate change debates across Europe and the national power grid.

 

Key Points

Germany Nuclear Phase-Out ends reactors, shifting to renewables to balance energy security, emissions, climate goals.

✅ Three reactors closed: Emsland, Isar II, Neckarwestheim II

✅ Pivot to renewables, efficiency, and grid resilience

✅ Continued roles in fuel fabrication and decommissioning

 

Germany is no longer producing any electricity from nuclear power plants, a move widely seen as turning its back on nuclear for good.

Closures of the Emsland, Isar II, and Neckarwestheim II nuclear plants in Germany were expected. The country announced plans to phase out nuclear power in 2011. However, in the fall of 2022, with the Ukraine war constraining access to energy, especially in Europe, Germany decided to extend nuclear power operations for an additional few months to bolster supplies.

“This was a highly anticipated action. The German government extended the lifetimes of these plants for a few months but never planned beyond that,” David Victor, a professor of innovation and public policy at UC San Diego, said.

Responses to the closures ranged from aghast that Germany would shut down a clean source of energy production, especially as Europe is losing nuclear power just when it really needs energy. In contrast, the global response to anthropogenic climate change continues to be insufficient to celebratory that the country will avoid any nuclear accidents like those that have happened in other parts of the world.

A collection of esteemed scientists, including two Nobel laureates and professors from MIT and Columbia, made a last-minute plea in an open letter published on April 14 on the nuclear advocacy group’s website, RePlaneteers, to keep the reactors operating, reviving questions about a resurgence of nuclear energy in Germany today.

“Given the threat that climate change poses to life on our planet and the obvious energy crisis in which Germany and Europe find themselves due to the unavailability of Russian natural gas, we call on you to continue operating the last remaining German nuclear power plants,” the letter states.

The open letter states that the Emsland, Isar II, and Neckarwestheim II facilities provided more than 10 million German households with electricity, even as some officials argued that nuclear would do little to solve the gas issue then. That’s a quarter of the population.

“This is hugely disappointing, when a secure low carbon 24/7 source of energy such as nuclear was available and could have continued operation for another 40 years,” Henry Preston, spokesperson for the World Nuclear Association. “Germany’s nuclear industry has been world-class. All three reactors shut down at the weekend performed extremely well.”

Despite the shutdown, some segments of nuclear industrial processes will continue to operate. “Germany’s nuclear sector will continue to be first class in the wider nuclear supply chain in areas such as fuel fabrication and decommissioning,” Preston said.

While the open letter did not succeed in keeping the nuclear reactors open, it does underscore a crucial reason why nuclear power has been part of global energy conversations recently, with some arguing it is a needed option for climate policy after a generational lull in the construction of nuclear power plants: climate change.

Generating electricity with nuclear reactors does not create any greenhouse gases. And as global climate change response efforts continue to fall short of emission targets, atomic energy is getting renewed consideration, and Germany has even considered a U-turn on its phaseout amid renewed debate.

N.L. lags behind Canada in energy efficiency, but there's a silver lining to the stats

Newfoundland and Labrador Energy Efficiency faces low rankings yet signs of progress: heat pumps, EV charging networks, stricter building codes, electrification to tap Muskrat Falls power and cut greenhouse gas emissions and energy poverty.

 

Key Points

Policies and programs improving N.L.'s energy use via electrification, EVs, heat pumps, and stronger building codes.

✅ Ranks last provincially but showing policy momentum

✅ Heat pump grants and EV charging network underway

✅ Stronger building codes and electrification can cut emissions

 

Ah, another day, another depressing study that places Newfoundland and Labrador as lagging behind the rest of Canada.

We've been in this place before — least-fit kids, lowest birthrate — and now we can add a new dubious distinction to the pile: a ranking of the provinces according to energy efficiency placed Newfoundland and Labrador last.

Efficiency Canada released its first-ever provincial scorecard Nov. 20, comparing energy efficiency policies among the provinces. With energy efficiency a key part of reducing greenhouse gas emissions, Newfoundland and Labrador sat in 10th place, noted for its lack of policies on everything from promoting EV uptake in Atlantic Canada to improving efficient construction codes.

But before you click away to a happier story (about, say, a feline Instagram superstar) one of the scorecard's authors says there's a silver lining to the statistics.

"It's not that Newfoundland and Labrador is doing anything badly; it's just that it could do more," said Brendan Haley, the policy director at Efficiency Canada, a new think tank based at Carleton University.

"There's just a general lack of attention to implementing efficiency policies relative to other jurisdictions, including New Brunswick's EV rebate programs on transportation."

Looking at the scorecard and comparing N.L. with British Columbia, which snagged the No. 1 spot, isn't a great look. B.C. scored 56 points out of a possible 100, while N.L. got just 15.

Haley pointed out that B.C.'s provincial government is charting progress toward 2032, when all new builds will have to be net-zero energy ready; that is, buildings that can produce as much clean energy as they consume.  

While it might not be feasible to emulate that to a T here, Haley said the province could be mandating better energy efficiency standards for new, large building projects, and, at the same time, promote electrification of such projects as a way to soak up some of that surplus Muskrat Falls electricity.

Staring down Muskrat's 'extraordinary' pressure on N.L. electricity rates

It's impossible to talk about energy efficiency in N.L. without considering that dam dilemma. As Muskrat Falls comes online, likely at the end of 2020, customer power rates are set to rise in order to pay for it, and the province is still trying to figure out the headache that is rate mitigation.

"There is a strategic choice to be made in Newfoundland and Labrador," Haley told CBC Radio's On The Go.

While having more customers using Muskrat Falls power can help with rate mitigation, including through initiatives like N.L.'s EV push to grow demand, Haley noted simply using its excess electricity for the sake of it isn't a great goal.

"That should not be an excuse, I think, to almost have a policy of wasting energy on purpose, or saying that we don't need programs that help save electricity anymore," he said.

Energy poverty
Lots of N.L. homeowners are currently feeling a chill from the spectre of rising electricity rates.

Of course, that draft could be coming from a poorly insulated and heated house, as Efficiency Canada noted 38 per cent of all households in N.L. live in what it calls "energy poverty," where they spend more than six per cent of their after-tax income on energy — that's the second highest such rate in the country.

That poverty speaks for a need for N.L.to boost efficiency incentives for vulnerable populations, although Haley noted the government is making progress. The province recently expanded its home energy savings program, doubling in the last budget year to $2 million, which gives grants to low income households for upgrades like insulation.

Can you guess what products are selling like hotcakes as Muskrat Falls looms? Heat pumps

And since Efficiency Canada compiled its scorecard, the province has introduced a $1-million heat pump program, in which 1,000 homeowners could receive $1,000 toward the purchase of a heat pump. 

That program began accepting applications Oct. 15, and one month in, has had 682 people apply, according to the Department of Municipal Affairs and Environment, along with thousands of inquiries.

Heat pump popularity
Even without that program, heat pump sales have skyrocketed in the province since 2017. That popularity doesn't come as much of a surprise to Darren Brake, the president of KSAB Construction in Corner Brook.

With more than two decades in the home building business, he's been seeing consumer demand for home energy efficiency rise to the point where a year ago, his company transitioned into only building third-party certified energy efficient homes.

"Everybody's really concerned about the escalating power costs and energy costs, I assume because of Muskrat Falls," he said.

"It's evolving now, as we speak. Everybody is all about that monthly payment."

Brake uses spray foam installation in every house he builds, to seal up any potential leaks. Without sealing the building envelope, he says, a heat pump is far less efficient. (Lindsay Bird/CBC)
And in the weakest housing market in the province in half a century, Brake has been steadily moving his, building and selling seven in the last year.

Brake's houses include heat pumps, but he said the real savings come from their heavily insulated walls, roof and floors. Homeowners looking to install a heat pump in their leaky old house, he said, won't see lower power bills in quite the same way.

"They are energy efficient, but it's more about the building envelope to make a home efficient and easy to heat. You can put a heat pump in an older home that leaks a lot of air, and you won't get the same results," he said.

Charging network coming
The other big piece to the efficiency puzzle — in the scorecard's eyes — is electric vehicles. Those could, again, use some of that Muskrat Falls energy, as well as curtail gas guzzling, but Efficiency Canada pointed to a lack of policies and incentives surrounding electrifying transportation, such as Nova Scotia's vehicle-to-grid pilot that illustrates innovation elsewhere.

Unlike Quebec or B.C., the province doesn't offer a rebate for buying EVs, even as N.W.T. encourages EVs through targeted measures, and while electric vehicles got loud applause at the House of Assembly last week, it was absent of any policy or announcement beyond the province unveiling a EV licence plate design to be used in the near future.

Electric-vehicle charging network planned for N.L. in 2020

But since the scorecard was tallied, NL Hydro has unveiled plans for a Level 3 charging network for EVs across the island, dependent on funding, with N.L.'s first fast-charging network seen as just the beginning for local drivers.

NL Hydro says while its request for proposals for an island-wide charging network closed earlier in November, there is no progress update yet, even as N.B.'s fast-charging rollout advances along the Trans-Canada. (Credit: iStock/Getty Images)
That cash appears to still be in limbo, as "we are still progressing through the funding process," said an NL Hydro spokesperson in an email, with no "additional details to release at this time."

Still, the promise of a charging network — plus the swift uptake on the heat pump program — could boost N.L.'s energy efficiency scorecard next time it's tallied, said Haley.

"It is encouraging to see the province moving forward on smart and efficient electrification," he said.

In Europe, A Push For Electricity To Solve The Climate Dilemma

EU Electrification Strategy 2050 outlines shifting transport, buildings, and industry to clean power, accelerating EV adoption, heat pumps, and direct electrification to meet targets, reduce emissions, and replace fossil fuels with renewables and low-carbon grids.

 

Key Points

EU plan to cut emissions 95% by 2050 by electrifying transport, buildings and industry with clean power.

✅ 60% of final energy from electricity by 2050

✅ EVs dominate transport; up to 63% electric share

✅ Heat pumps electrify buildings; industry to 50% direct

 

The European Union has one of the most ambitious carbon emission reduction goals under the global Paris Agreement on climate change – a 95% reduction by 2050.

It seems that everyone has an idea for how to get there. Some are pushing nuclear energy. Others are pushing for a complete phase-out of fossil fuels and a switch to renewables.

Today the European electricity industry came out with their own plan, amid expectations of greater electricity price volatility in Europe in the coming years. A study published today by Eurelectric, the trade body of the European power sector, concludes that the 2050 goal will not be possible without a major shift to electricity in transport, buildings and industry.

The study finds that for the EU to reach its 95% emissions reduction target, electricity needs to cover at least 60 percent of final energy consumption by 2050. This would require a 1.5 percent year-on-year growth of EU electricity use, with evidence that EVs could raise electricity demand significantly in other markets, while at the same time reducing the EU’s overall energy consumption by 1.3 percent per year.

Transport is one of the areas where electrification can deliver the most benefit, because an electric car causes far less carbon emissions than a conventional vehicle, with e-mobility emerging as a key driver of electricity demand even if that electricity is generated in a fossil fuel power plant.

In the most ambitious scenario presented by the study, up to 63 percent of total final energy consumption in transport will be electric by 2050, and some analyses suggest that mass adoption of electric cars could occur much sooner, further accelerating progress.

Building have big potential as well, according to the study, with 45 to 63 percent of buildings energy consumption could be electric in 2050 by converting to electric heat pumps. Industrial processes could technically be electrified with up to 50 percent direct electrification in 2050, according to the study. The relative competitiveness of electricity against other carbon-neutral fuels will be the critical driver for this shift, but grid carbon intensity differs across markets, such as where fossil fuels still supply a notable share of generation.
