Doyle Sailmakers, a local company with an international reach, may be on the verge of turning ocean currents into electric currents, Gov. Deval Patrick learned on a visit to the Salem sail loft recently.

Doyle is working with a New Hampshire company to fashion an efficient underwater turbine to harness steady, underwater currents for power. The design of the turbine's blades relies on Doyle's deep understanding of how sails power boats.

The potential for a sailmaker to help bolster the state's green economy and jobs was not lost on Patrick.

"What I learned today is there are some very, very intriguing new technologies being developed here," Patrick said.

Patrick, Salem Mayor Kim Driscoll and state Rep. John Keenan, D-Salem, and their respective entourages visited Doyle's headquarters in a new industrial park on Swampscott Road.

Doyle Sailmakers started in August 1982 in Marblehead at a time when there were 10 or 12 sailmakers in town, owner Robbie Doyle said. Several years ago, it moved to Salem, where it employs 35 people locally, down two or three from a few years ago.

In addition, there are 70 Doyle sail lofts around the world, and the company not only makes and services sails for local day sailors, its sails propel some of the world's largest and most expensive super yachts.

The sailmaker's motto, "Better Engineered Sails," may take on a whole new meaning if the company can create efficient underwater power turbines.

The governor and officials toured the cavernous sail loft, gingerly stepping on slick floors as workers knelt to work on sails spread around the 32,000-square-foot facility.

"I have never had so many blue blazers in my facility at once," said Doyle's wife, Janet.

While Patrick liked what he saw, he did not come bearing state help right away.

"I don't know yet what we can do, but one of the conversations we were having is what their needs are to help them get to the next stage," Patrick said.

The state has, through the Regional Greenhouse Gas Initiative, some resources the state can tap to invest in green technologies, Patrick said.

Massachusetts is one of 10 states that sell power plant emission allowances through auctions and invest the proceeds in energy-efficient and renewable energy projects, according to RGGI's website.

"Doyle grew and expanded and helped... embrace that technology because of a city investment and a state investment to actually put them here," Driscoll said. "They used to be in Marblehead, a much smaller company, a much smaller footprint. Now they are here, building sails, building airships, talking about other innovation."

Driscoll pointed out the building that houses the sail loft used to house Maynard Plastics. Several years ago, the facility was sold and carved into industrial condominiums.

"Now it's 10 different companies," many of which focus on innovation, Driscoll said. Driscoll met with Doyle a week ago, and, after she did so, she decided to take Patrick out to see what they were working on.

"You could see they are not designing it as a renewable energy product," Driscoll said. "They are designing it as an economic way to deliver electricity that happens to have a lot of renewable benefits."

So how did a sail company come to design an underwater power turbine?

Part of the reason, Doyle said, is the company takes an engineering approach to sail making. Doyle studied applied physics at Harvard University, and Doyle's son, Tyler, is the company's chief engineer.

About a year ago, Robert Houvener, president and founder of ScaleTera Renewable Energy LLC of Hollis, N.H., approached Doyle to create a new, more efficient water turbine using sail material.

The idea was to build big blades out of sail fabric that might withstand ocean currents.

"It turned out it was not cost-effective," Robbie Doyle said. But Doyle kept on working on the project.

"I loved everything I saw," Tyler said. "I had been working on wind turbines for the year or two before that." Tyler had been put off by the wind turbine's enormous cost for not a lot of power.

"The second you looked at the economics of this project, it just made so much more sense," Tyler said.

Turbines helped mills power the industrial revolution by harnessing power from swift-flowing rivers. However, traditional water turbines require high-speed currents of 8 to 10 knots and building structures that can stand up to that type of force, making them too expensive to build.

Doyle's technology requires slower but steady currents of about 3 knots. The turbines can be assembled in standard shipyards and don't rely on special, and expensive, ships and facilities.

The goal is to someday harness the currents of the Gulf Stream, the swift Atlantic Ocean currents off the East Coast or the Bosphorus Strait in Turkey.

"We had never built a propeller blade in our life," Robbie Doyle said, "but, again, it's just like a twisted sail, it's no different."

If all goes according to plan, Robbie Doyle said it could be a billion dollars-plus business in six years.

"We just have to come up with a technology, which we've done," Doyle said. "Now we just have to build it."

P.E.I. government exploring ways for communities to generate their own electricity

P.E.I. Community Energy Independence empowers local microgrids through renewable generation, battery storage, and legislative reform, enabling community-owned power, stable electricity rates, and grid-friendly distributed generation across Island communities with wind, biomass, and net metering models.

 

Key Points

A program enabling communities to generate and store renewable power under supportive laws and grid-friendly models.

✅ Legislative review of Electric Power and Renewable Energy Acts

✅ Community microgrids with wind, biomass, and battery storage

✅ Grid integration without raising rates via Maritime Electric

 

The P.E.I. government is taking steps to review energy legislation and explore new options when it comes to generating power across Island communities.

Energy Minister Steven Myers said one of those options will be identifying ways for Island communities to generate their own energy, aligning with a federal electrification study now examining how electricity can reduce or eliminate fossil fuels. 

He said the move would provide energy independence, create jobs and economic development, and save the communities on their energy bills, as seen with an electricity bill credit in Newfoundland that eased costs for consumers.

But the move will require sweeping legislative changes, that may include the merging of the Electric Power Act and the Renewable Energy Act, similar to an electricity market overhaul in Connecticut seen in other jurisdictions.  

Myers said creating energy independence should ensure a steady supply of electricity while also ensuring costs remain reasonable for P.E.I. residents, even as a Nova Scotia electricity rate hike highlights regional cost pressures.   

"We have communities that are looking to generate their own electricity for their own needs," said Myers, adding the province will not dictate what energy sources communities can invest in. 

He also said the province wants to find new community-based models that will complement existing services.

"How do we do that in a way that we don't impact the grid, that we don't impact the service that Maritime Electric is delivering, mindful of a seasonal rate backlash in New Brunswick that illustrates consumer concerns, that we don't drive up the rates for all other Islanders."

Last fall, a group of P.E.I. MLAs traveled to Samsø, a small Danish island, where they learned about renewable and sustainable energy systems being used there.

The province is looking at storage options so it can store power generated during the day to be used in the evening when electricity use is at its highest. (CBC)
Samsø produces 100 per cent of its electricity from wind and biomass, and utilities like HECO meeting renewable goals early show how quickly transitions can occur. The P.E.I. government said the Island produces 25 per cent of its electricity from wind. 

Following the trip, Myers said he was impressed by the control the island had over its energy production and would like to see if a similar model could work on P.E.I. 

Myers said the legislative review will also look at different ways to store energy on the Island. 

He said that will allow communities to sell that excess energy into the provincial electricity grid, and those revenues could be redirected into that community's priorities. 

'For the survival and the future of their community'
"This is kind of a model that we had suggested that would be in place that would allow people in their own community to produce a revenue stream for themselves that they could then turn into projects like rinks, or parks, or tennis courts or whatever it is that community thinks is the most important thing for the survival and the future of their community," said Myers.

The province said Maritime Electric, Summerside Electric and the P.E.I. Energy Corporation will be involved in the review, recognizing that a Nova Scotia ruling on rate-setting powers underscores regulatory limits 

Government also wants to hear from Islanders and will be accepting written submissions beginning Monday. Myers said the province is also planning to host public consultations, but because of COVID-19, those will be held virtually in mid-June.

Myers calls this a major move, one that will take time. He said he doesn't expect the legislation to be made public until the spring of 2021.

"I want to make sure we take our time and do the proper consultation."

Trump's Proposal on Ukraine's Nuclear Plants Sparks Controversy

Ukraine Nuclear Plant Ownership Proposal outlines U.S. management of Ukrainian reactors amid the Russia-Ukraine war, citing nuclear safety, energy security, and IAEA oversight; Kyiv rejects ownership transfer, especially regarding Zaporizhzhia under Russian control.

 

Key Points

U.S. control of Ukraine's nuclear plants for safety; Kyiv rejects transfer, citing sovereignty risks at Zaporizhzhia.

✅ U.S. proposal to manage Ukraine's reactors amid war

✅ Kyiv refuses ownership transfer; open to investment

✅ Zaporizhzhia under Russian control raises safety risks

 

In the midst of the ongoing conflict between Russia and Ukraine, U.S. President Donald Trump has proposed a controversial idea: Ukraine should give its nuclear power plants to the United States for safekeeping and management. This suggestion came during a phone call with Ukrainian President Volodymyr Zelenskyy, wherein Trump expressed the belief that American ownership of these nuclear plants could offer them the best protection amid the ongoing war. But Kyiv, while open to foreign support, has firmly rejected the idea of transferring ownership, especially as the Zaporizhzhia nuclear plant remains under Russian occupation.

Ukraine’s nuclear energy infrastructure has always been a vital component of its power generation. Before the war, the country’s four nuclear plants supplied nearly half of its electricity. As Russia's military forces target Ukraine's energy infrastructure, including power plants and coal mines, international watchdogs like the IAEA have warned of nuclear risks as these nuclear facilities have become crucial to maintaining the nation’s energy stability. The Zaporizhzhia plant, in particular, has attracted international concern due to its size and the ongoing threat of a potential nuclear disaster.

Trump’s Proposal and Ukraine’s Response

Trump’s proposal of U.S. ownership came as a response to the ongoing threats posed by Russia’s occupation of the Zaporizhzhia plant. Trump argued that the U.S., with its expertise in running nuclear power plants, could safeguard these facilities from further damage and potential nuclear accidents. However, Zelenskyy quickly clarified that the discussion was only focused on the Zaporizhzhia plant, which is currently under Russian control. The Ukrainian president emphasized that Kyiv would not entertain the idea of permanently transferring ownership of its nuclear plants, even though they would welcome investment in their restoration and modernization, particularly after the war.

The Zaporizhzhia nuclear plant has been a focal point of geopolitical tensions since Russia's occupation in 2022. Despite being in "cold shutdown" to prevent further risk of explosions, the facility remains a major concern due to its potential to cause a nuclear disaster. Ukrainian officials, along with international observers, have raised alarm about the safety risks posed by the plant, including mines at Zaporizhzhia reported by UN watchdogs, which is situated in a war zone and under the control of Russian forces who are reportedly neglecting proper safety protocols.

The Fear of a Nuclear Provocation

Ukrainians have expressed concerns that Trump’s proposal could embolden Russia to escalate tensions further, even as a potential agreement on power-plant attacks has been discussed by some parties. Some fear that any attempt to reclaim the plant by Ukraine could trigger a Russian provocation, including a deliberate attack on the plant, which would have catastrophic consequences for both Ukraine and the broader region. The analogy is drawn with the destruction of the Nova Kakhovka dam, which Ukraine accuses Russia of sabotaging, an act that severely disrupted water supplies to the Zaporizhzhia plant. Ukrainian military officials, including Ihor Romanenko, a former deputy head of Ukraine’s armed forces, warned that Trump’s suggestion might be an exploitation of Ukraine’s vulnerable position in the ongoing war.

Despite these fears, there are some voices within Ukraine, including former employees of the Zaporizhzhia plant, who believe that a deliberate attack by Russian forces is unlikely. They argue that the Russian military needs the plant in functioning condition for future negotiations, with Russia building new power lines to reactivate the site as part of that calculus, and any damage could reduce its value in such exchanges. However, the possibility of Russian negligence or mismanagement remains a significant risk.

The Strategic Role of Ukraine's Nuclear Plants

Ukraine's nuclear plants were a cornerstone of the country’s energy sector long before the conflict began. In recent years, as Ukraine lost access to coal resources in the Donbas region due to Russian occupation, nuclear power became even more vital, alongside a growing focus on wind power to improve resilience. The country’s reliance on these plants grew as Russia launched a sustained campaign to destroy Ukraine’s energy infrastructure, including attacks on nuclear power stations.

The Zaporizhzhia plant, in particular, holds strategic importance not only due to its size but also because of its location in southeastern Ukraine, an area that has been at the heart of the conflict. Despite being in Russian hands, the plant’s reactors have been safely shut down, reducing the immediate risk of a nuclear explosion. However, the plant’s future remains uncertain, as Russia’s long-term control over it could disrupt Ukraine’s energy security for years to come.

Wider Concerns About Aging Nuclear Infrastructure

Beyond the geopolitical tensions, there are broader concerns about the aging infrastructure of Ukraine's nuclear power plants. International watchdogs, including the environmentalist group Bankwatch, have criticized these facilities as “zombie reactors” due to their outdated designs and safety risks. Experts have called for Ukraine to decommission some of these reactors, fearing that they are increasingly unsafe, especially in the context of a war.

However, Ukrainian officials, including Petro Kotin, head of Energoatom (Ukraine's state-owned nuclear energy company), argue that these reactors are still functional and critical to Ukraine's energy needs. The ongoing conflict, however, complicates efforts to modernize and secure these facilities, which are increasingly vulnerable to both physical damage and potential nuclear hazards.

The Global Implications

Trump's suggestion to take control of Ukraine's nuclear power plants has raised significant concerns on the international stage. Some fear that such a move could set a dangerous precedent for nuclear security and sovereignty. Others see it as an opportunistic proposal that exploits Ukraine's wartime vulnerability.

While the future of Ukraine's nuclear plants remains uncertain, one thing is clear: these facilities are now at the center of a geopolitical struggle that could have far-reaching consequences for the energy security of Europe and the world. The safety of these plants and their role in Ukraine's energy future will remain a critical issue as the war continues and as Ukraine navigates its relations with both the U.S. and Russia, with the grid even having resumed electricity exports at times.

Three Mile Island at center of energy debate: Let struggling nuclear plants close or save them

Three Mile Island Nuclear Debate spotlights subsidies, carbon pricing, wholesale power markets, grid reliability, and zero-emissions goals as Pennsylvania weighs keeping Exelon's reactor open amid natural gas competition and flat electricity demand.

 

Key Points

Debate over subsidies, carbon pricing, and grid reliability shaping Three Mile Island's zero-emissions future.

✅ Zero emissions credits vs market integrity

✅ Carbon pricing to value clean baseload power

✅ Closure risks jobs, tax revenue, and reliability

 

Three Mile Island is at the center of a new conversation about the future of nuclear energy in the United States nearly 40 years after a partial meltdown at the Central Pennsylvania plant sparked a national debate about the safety of nuclear power.

The site is slated to close in just two years, a closure plan Exelon has signaled, unless Pennsylvania or a regional power transmission operator delivers some form of financial relief, says Exelon, the Chicago-based power company that operates the plant.

That has drawn the Keystone State into a growing debate: whether to let struggling nuclear plants shut down if they cannot compete in the regional wholesale markets where energy is bought and sold, or adopt measures to keep them in the business of generating power without greenhouse gas emissions.

""The old compromise — that in order to have a reliable, affordable electric system you had to deal with a significant amount of air pollution — is a compromise our new customers today don't want to hear about.""
-Joseph Dominguez, Exelon executive vice president
Nuclear power plants produce about two-thirds of the country's zero-emissions electricity, a role many view as essential to net-zero emissions goals for the grid.

The debate is playing out as some regions consider putting a price on planet-warming carbon emissions produced by some power generators, which would raise their costs and make nuclear plants like Three Mile Island more viable, and developments such as Europe's nuclear losses highlight broader energy security concerns.

States that allow nuclear facilities to close need to think carefully because once a reactor is powered down, there's no turning back, said Jake Smeltz, chief of staff for Pennsylvania State Sen. Ryan Aument, who chairs the state's Nuclear Energy Caucus.

"If we wave goodbye to a nuclear station, it's a permanent goodbye because we don't mothball them. We decommission them," he told CNBC.

Three Mile Island's closure would eliminate more than 800 megawatts of electricity output. That's roughly 10 percent of Pennsylvania's zero-emissions energy generation, by Exelon's calculation. Replacing that with fossil fuel-fired power would be like putting roughly 10 million cars on the road, it estimates.

A closure would also shed about 650 well-paying jobs, putting the just transition challenge in focus for local workers and communities, tied to about $60 million in wages per year. Dauphin County and Londonderry Township, a rural area on the Susquehanna River where the plant is based, stand to lose $1 million in annual tax revenue that funds schools and municipalities. The 1,000 to 1,500 workers who pack local hotels, stores and restaurants every two years for plant maintenance would stop visiting.

Pennsylvanians and lawmakers must now decide whether these considerations warrant throwing Exelon a lifeline. It's a tough sell in the nation's second-largest natural gas-producing state, which already generates more energy than it uses. And time is running out to reach a short-term solution.

"What's meaningful to us is something where we could see the results before we turn in the keys, and we turn in the keys the third quarter of '19," said Joseph Dominguez, Exelon's executive vice president for governmental and regulatory affairs and public policy.

The end of the nuclear age?

The problem for Three Mile Island is the same one facing many of the nation's 60 nuclear plants: They are too expensive to operate.

Financial pressure on these facilities is mounting as power demand remains stagnant due to improved energy efficiency, prices remain low for natural gas-fired generation and costs continue to fall for wind and solar power.

Three Mile Island is something of a special case: The 1979 incident left only one of its two reactors operational, but it still employs about as many people as a plant with two reactors, making it less efficient. In the last three regional auctions, when power generators lock in buyers for their future energy generation, no one bought power from Three Mile Island.

But even dual-reactor plants are facing existential threats. FirstEnergy Corp's Beaver Valley will sell or close its nuclear plant near the Pennsylvania-Ohio border next year as it exits the competitive power-generation business, and facilities like Ohio's Davis-Besse illustrate what's at stake for the region.

Five nuclear power plants have shuttered across the country since 2013. Another six have plans to shut down, and four of those would close well ahead of schedule. An analysis by energy research firm Bloomberg New Energy Finance found that more than half the nation's nuclear plants are facing some form of financial stress.

Today's regional energy markets, engineered to produce energy at the lowest cost to consumers, do not take into account that nuclear power generates so much zero-emission electricity. But Dominguez, the Exelon vice president, said that's out of step with a world increasingly concerned about climate change.

"What we see is increasingly our customers are interested in getting electricity from zero air pollution sources," Dominguez said. "The old compromise — that in order to have a reliable, affordable electric system you had to deal with a significant amount of air pollution — is a compromise our new customers today don't want to hear about."

Strange bedfellows

Faced with the prospect of nuclear plant closures, Chicago and New York have both allowed nuclear reactors to qualify for subsidies called zero emissions credits. Exelon lobbied for the credits, which will benefit some of its nuclear plants in those states.

Even though the plants produce nuclear waste, some environmental groups like the Natural Resources Defense Council supported these plans. That's because they were part of broader packages that promote wind and solar power, and the credits for nuclear are not open-ended. They essentially provide a bridge that keeps zero-emissions power from nuclear reactors on the grid as renewable energy becomes more viable.

Lawmakers in Pennsylvania, Ohio and Connecticut are currently exploring similar options. Jake Smeltz, chief of staff to state Sen. Aument, said legislation could surface in Pennsylvania as soon as this fall. The challenge is to get people to consider the attributes of the sources of their electricity beyond just cost, according to Smeltz.

"Are the plants worth essentially saving? That's a social choice. Do they provide us with something that has benefits beyond the electrons they make? That's the debate that's been happening in other states, and those states say yes," he said.

Subsidies face opposition from anti-nuclear energy groups like Three Mile Island Alert, as well as natural gas trade groups and power producers who compete against Exelon by operating coal and natural gas plants.

"Where we disagree is to have an out-of-market subsidy for one specific company, for a technology that is now proven and mature in our view, at the expense of consumers and the integrity of competitive markets," NRG Energy Mauricio Gutierrez told analysts during a conference call this month.

Smeltz notes that power producers like NRG would fill in the void left by nuclear plants as they continue to shut down.

"The question that I think folks need to answer is are these programs a bailout or is the opposition to the program a payout? Because at the end of the day someone is going to make money. The question is who and how much?" Smeltz said.

Changing the market

Another critic is PJM Interconnection, the regional transmission organization that operates the grid for 13 states, including Pennsylvania, and Washington, D.C.

The subsidies distort price formation and inject uncertainty into the markets, says Stu Bresler, senior vice president in charge of operations and markets at PJM.

The danger PJM sees is that each new subsidy creates a precedent for government intervention. The uncertainty makes it harder for investors to determine what sort of power generation is a sound investment in the region, Bresler explained. Those investors could simply decide to put their capital to work in other energy markets where the regulatory outlook is more stable, ultimately leading to underinvestment in places where government intervenes, he added.

PJM believes longer-term, regional approaches are more appropriate. It has produced research that outlines how coal plants and nuclear energy, which provide the type of stable energy that is still necessary for reliable power supply, could play a larger role in setting prices. It is also preparing to release a report on how to put a price on carbon emissions in all or parts of the regional grid.

"If carbon emissions are the concern and that is the public policy issue with which policymakers are concerned, the simple be-all answer from a market perspective is putting a price on carbon," Bresler said.

Three Mile Island could be viable if natural gas prices rose from below $3 per million British thermal units to about $5 per mmBtu and if a "reasonable" price were applied to carbon, according to Exelon's Dominguez. He is encouraged by the fact that conversations around new pricing models and carbon pricing are gaining traction.

"The great part about this is everybody understands we have a major problem. We're losing some of the lowest-cost, cleanest and most reliable resources in America," Dominguez said.

Wind Denmark - summer's autumn weather provides extraordinarily low electricity prices

Western Denmark Negative Electricity Prices stem from wind energy oversupply, grid congestion, and limited interconnector capacity via Nord Pool and TenneT, underscoring electrification needs, renewable integration, special regulation, and system flexibility.

 

Key Points

They are sub-zero power prices from wind oversupply, weak interconnectors, low demand, and balancing needs.

✅ Caused by high wind output, low demand, and export bottlenecks

✅ Limited Nord Pool interconnector capacity depresses prices

✅ Special regulation and district heating absorb excess power

 

A downturn in the cable connection to Norway and Sweden, together with low electricity consumption and high electricity production, has pushed down European electricity prices to a negative level in Western Denmark.

A sign that the electrification of society is urgently needed, says Soren Klinge, head of electricity market at Wind Denmark today.

The heavy winds during the first weekend of July, unlike periods when cheap wind power wanes in the UK, have not only had consequences for the Danes who had otherwise been looking forward to spending their first days at home in the garden or at the beach. It has also pushed down prices in the electricity market to a negative level, which especially the West Danish wind turbine owners have had to notice.

'The electricity market is currently affected by an unfortunate coincidence of various factors that have a negative impact on the electricity price: a reduced export capacity to the other Nordic countries, a low electricity consumption and a high electricity generation, reflecting broader concerns over dispatchable power shortages in Europe today. Unfortunately, the coincidence of these three factors means that the price base falls completely out of the market. This is another sign that the electrification of society is urgently needed, 'explains Soren Klinge, electricity market manager at Wind Denmark.

According to the European power exchange Nord Pool Spot, where UK peak power prices are also tracked, the cable connection to Sweden is expected to return to full capacity from 19 July. The connection between Jutland and Norway is only expected to return to full capacity in early September.

2000 MWh / hour in special regulation

During the windy weather on Monday morning, July 6, up to 2000 MWh / hour was activated at national level in the form of so-called special regulation. Special regulation is the designation that the German system operator TenneT switches off Danish electricity generation at cogeneration plants and wind turbines in order to help with the balancing of the German power system during such events. In addition, electric boilers at the cogeneration plants also contribute by using the electricity from the electricity grid and converting it to district heating for the benefit of Danish homes and businesses.

'The Danish wind turbines are probably the source of most of the special regulation, because there are very few cogeneration units to down-regulate electricity generation. Of course, it is positive to see that we have a high degree of flexibility in the wind-based power system at home. That being said, Denmark does not really get ahead with the green transition, even as its largest energy company plans to stop using coal by 2023, until we are able to raise electricity consumption based on renewable energy.

No time to be silent on NZ's electricity future

New Zealand Renewable Energy Strategy examines decarbonisation, GHG emissions, and net energy as electrification accelerates, expanding hydro, geothermal, wind, and solar PV while weighing intermittency, storage, materials, and energy security for a resilient power system.

 

Key Points

A plan to expand electricity generation, balancing decarbonisation, net energy limits, and energy security.

✅ Distinguishes decarbonisation targets from renewable capacity growth

✅ Highlights net energy limits, intermittency, and storage needs

✅ Addresses materials, GHG build-out costs, and energy security

 

The Electricity Authority has released a document outlining a plan to achieve the Government’s goal of more than doubling the amount of electricity generated in New Zealand over the next few decades.

This goal is seen as a way of both reducing our greenhouse gas (GHG) emissions overall, as everything becomes electrified, and ensuring we have a 100 percent renewable energy system at our disposal. Often these two goals are seen as being the same – to decarbonise we must transition to more renewable energy to power our society.

But they are quite different goals and should be clearly differentiated. GHG emissions could be controlled very effectively by rationing the use of a fossil fuel lockdown approach, with declining rations being available over a few years. Such a direct method of controlling emissions would ensure we do our bit to remain within a safe carbon budget.

If we took this dramatic step we could stop fretting about how to reduce emissions (that would be guaranteed by the rationing), and instead focus on how to adapt our lives to the absence of fossil fuels.

Again, these may seem like the same task, but they are not. Decarbonising is generally thought of in terms of replacing fossil fuels with some other energy source, signalling that a green recovery must address more than just wind capacity. Adapting our lives to the absence of fossil fuels pushes us to ask more fundamental questions about how much energy we actually need, what we need energy for, and the impact of that energy on our environment.

MBIE data indicate that between 1990 and 2020, New Zealand almost doubled the total amount of energy it produced from renewable energy sources - hydro, geothermal and some solar PV and wind turbines.

Over this same time period our GHG emissions increased by about 25 percent. The increase in renewables didn’t result in less GHG emissions because we increased our total energy use by almost 50 percent, mostly by using fossil fuels. The largest fossil fuel increases were used in transport, agriculture, forestry and fisheries (approximately 60 percent increases for each).

These data clearly demonstrate that increasing renewable energy sources do not necessarily result in reduced GHG emissions.

The same MBIE data indicate that over this same time period, the amount of Losses and Own Use category for energy use more than doubled. As of 2020 almost 30 percent of all energy consumed in New Zealand fell into this category.

These data indicate that more renewable energy sources are historically associated with less energy actually being available to do work in society.

While the category Losses and Own Use is not a net energy analysis, the large increase in this category makes the call for a system-wide net energy analysis all the more urgent.

Net energy is the amount of energy available after the energy inputs to produce and deliver the energy is subtracted. There is considerable data available indicating that solar PV and wind turbines have a much lower net energy surplus than fossil fuels.

And there is further evidence that when the intermittency and storage requirements are engineered into a total renewable energy system, the net energy of the entire system declines sharply. Could the Losses and Other Uses increase over this 30-year period be an indication of things to come?

Despite the importance of net energy analysis in designing a national energy system which is intended to provide energy security and resilience, there is not a single mention of net energy surplus in the EA reference document.

So over the last 30 years, New Zealand has doubled its renewable energy capacity, and at the same time increased its GHG emissions and reduced the overall efficiency of the national energy system.

And we are now planning to more than double our renewable energy system yet again over the next 30 years, even as zero-emissions electricity by 2035 is being debated elsewhere. We need to ask if this is a good idea.

How can we expand New Zealand’s solar PV and wind turbines without using fossil fuels? We can’t.

How could we expand our solar PV and wind turbines without mining rare minerals and the hidden costs of clean energy they entail, further contributing to ecological destruction and often increasing social injustices? We can't.

Even if we could construct, deliver, install and maintain solar PV and wind turbines without generating more GHG emissions and destroying ecosystems and poor communities, this “renewable” infrastructure would have to be replaced in a few decades. But there are at least two major problems with this assumed scenario.

The rare earth minerals required for this replacement will already be exhausted by the initial build out. Recycling will only provide a limited amount of replacements.

The other challenge is that a mostly “renewable” energy system will likely have a considerably lower net energy surplus. So where, in 2060, will the energy come from to either mine or recycle the raw materials, and to rebuild, reinstall and maintain the next iteration of a renewable energy system?

There is currently no plan for this replacement. It is a serious misnomer to call these energy technologies “renewable”. They are not as they rely on considerable raw material inputs and fossil energy for their production and never ending replacement.

New Zealand is, of course, blessed with an unusually high level of hydro electric and geothermal power. New Zealand currently uses over 170 GJ of total energy per capita, 40 percent of which is “renewable”. This provides approximately 70 GJ of “renewable” energy per capita with our current population.

This is the average global per capita energy level from all sources across all nations, as calls for 100% renewable energy globally emphasize. Several nations operate with roughly this amount of total energy per capita that New Zealand can generate just from “renewables”.

It is worth reflecting on the 170 GJ of total energy use we currently consume. Different studies give very different results regarding what levels are necessary for a good life.

For a complex industrial society such as ours, 100 GJ pc is said to be necessary for a high levels of wellbeing, determined both subjectively (life satisfaction/ happiness measures), and objectively (e.g. infant mortality levels, female morbidity as an index of population health, access to nutritious food and educational and health resources, etc). These studies do not take into account the large amount of energy that is wasted either through inefficient technologies, or frivolous use, which effective decarbonization strategies seek to reduce.

Other studies that consider the minimal energy needed for wellbeing suggest a much lower level of per capita energy consumption is required. These studies take a different approach and focus on ensuring basic wellbeing is maintained, but not necessarily with all the trappings of a complex industrial society. Their results indicate a level of approximately 20 GJ per capita is adequate.

In either case, we in New Zealand are wasting a lot of energy, both in terms of the efficiency of our technologies (see the Losses and Own Use info above), and also in our uses which do not contribute to wellbeing (think of the private vehicle travel that could be done by active or public transport – if we had good infrastructure in place).

We in New Zealand need a national dialogue about our future. And energy availability is only one aspect. We need to discuss what our carrying capacity is, what level of consumption is sustainable for our population, and whether we wish to make adjustments in either our per capita consumption or our population. Both together determine whether we are on the sustainable side of carrying capacity. Currently we are on the unsustainable side, meaning our way of life cannot endure. Not a good look for being a good ancestor.

The current trajectory of the Government and Electricity Authority appears to be grossly unsustainable. At the very least they should be able to answer the questions posed here about the GHG emissions from implementing a totally renewable energy system, the net energy of such a system, and the related environmental and social consequences.

Public dialogue is critical to collectively working out our future. Allowing the current profit-driven trajectory to unfold is a recipe for disasters for our children and grandchildren.

Being silent on these issues amounts to complicity in allowing short-term financial interests and an addiction to convenience jeopardise a genuinely secure and resilient future. Let’s get some answers from the Government and Electricity Authority to critical questions about energy security.

Paris Finalises Energy Roadmap for 2025–2035 with Imminent Decree

France 2025–2035 Energy Roadmap accelerates carbon neutrality via renewables expansion, energy efficiency, EV adoption, heat pumps, hydrogen, CCS, nuclear buildout, and wind and solar targets, cutting fossil fuels and emissions across transport, housing, industry.

 

Key Points

A national plan to cut fossil use and emissions, boost renewables, and scale efficiency and clean technologies.

✅ Cuts fossil share to 30% by 2035 with efficiency gains

✅ Scales solar PV and wind; revives nuclear with EPR 2

✅ Electrifies transport and industry with EVs, hydrogen, CCS

 

Paris is on the verge of finalising its energy roadmap for the period 2025–2035, with an imminent decree expected to be published by the end of the first quarter of 2025. This roadmap is part of France's broader strategy to achieve carbon neutrality by 2050, aligning with wider moves toward clean electricity regulations in other jurisdictions.

Key Objectives of the Roadmap

The energy roadmap outlines ambitious targets for reducing greenhouse gas emissions across various sectors, including transport, housing, food, and energy. The primary goals are:

  • Reducing Fossil Fuel Dependency: Building on the EU's plan to dump Russian energy, the share of fossil fuels in final energy consumption is to fall from 60% in 2022 to 42% in 2030 and 30% in 2035.

  • Enhancing Energy Efficiency: A target of a 28.6% reduction in energy consumption between 2012 and 2030 is set, focusing on conservation and energy efficiency measures.

  • Expanding Decarbonised Energy Production: The roadmap aims to accelerate the development of renewable energies and the revival.

Sector-Specific Targets

  • Transport: The government aims to cut emissions by 31, focusing on the growth of electric vehicles, increasing public transport, and expanding charging infrastructure.

  • Housing: Emissions from buildings are to be reduced by 44%, with plans to replace 75% of oil-fired and install 1 million heat pumps.

  • Agriculture and Food: The roadmap includes measures to reduce emissions from agriculture by 9%, promoting organic farming and reducing the use of nitrogen fertilizers.

  • Industry: A 37% reduction in emissions is targeted through the use of electricity, biomass, hydrogen, and CO₂ capture and storage technologies informed by energy technology pathways outlined in ETP 2017.

Renewable Energy Targets

The roadmap sets ambitious targets for renewable energy production that align with Europe's ongoing electricity market reform efforts:

  • Photovoltaic Power: A sixfold increase in photovoltaic power between 2022

  • Offshore Wind Power: Reaching 18 gigawatts up from 0.6 GW

  • Onshore Wind Power: Doubling capacity from 21 GW to 45 GW over the same period.

  • Nuclear Power: The commissioning of the evolutionary power and the construction of six EPR 2 reactors, underpinned by France's deal on electricity prices with EDF to support long-term investment, with the potential for eight more.
     

Implementation and Governance

The final version of the roadmap will be adopted by decree, alongside a proposed electricity pricing scheme to address EU concerns, rather than being enshrined in law as required by the Energy Code. The government had previously abandoned the energy-climate planning. The decree is expected to be published at the end of the Multiannual Energy Program (PPE) and in the second half of the third National Low-Carbon Strategy (SNBC).

Paris's finalisation of its energy roadmap for 2025–2035 marks a significant step towards achieving carbon neutrality by 2050. The ambitious targets set across various sectors reflect a comprehensive approach to reducing greenhouse gas emissions and transitioning to a more sustainable energy system amid the ongoing EU electricity reform debate shaping market rules. The imminent decree will provide the legal framework necessary to implement these plans and drive the necessary changes across the country.
