Federal regulators received the first application in nearly three decades to build a new nuclear reactor, yet another sign that a long-dormant sector of the energy industry is springing back to life.

The applicant, NRG Energy of Princeton, N.J., alerted the Nuclear Regulatory Commission in advance, commission spokesman Scott Burnell said. The company wants to build two new reactors at its South Texas Project in Bay City.

The news has special significance in Pennsylvania: NRG's submission would be the first full, formal request for a construction and operating license since a meltdown at the Three Mile Island nuclear plant outside Harrisburg in 1979.

The Nuclear Regulatory Commission expects to receive up to six more this year from Duke Energy Corp., Dominion Resources Inc. and others, Burnell said.

That short list does not include PPL Corp. of Allentown, which is considering building a new reactor t its Susquehanna nuclear plant. In June, PPL sent a letter informing the Nuclear Regulatory Commission of its tentative plans to build a third reactor at the site, located about 75 miles northwest of the Lehigh Valley in Salem Township, Luzerne County.

The company, however, has yet to make a final decision on the matter.

"We're still in the stage of looking at the options and deciding," PPL spokesman George Lewis said. Energy companies see in nuclear plants an opportunity to affordably meet demand for electricity, which the Energy Information Administration is forecasting will grow by 42 percent by 2030.

High natural gas prices and the prospect of taxes or constraints on greenhouse gases are making gas- or coal-fired plants less attractive. At the same time, political support for nuclear energy is mounting. Indeed, Congress appears likely to remove a major hurdle to nuclear expansion - the immense financial risk. Both the Senate and the House recently passed bills that call for billions o dollars in government loan guarantees for the construction of new plants.

PPL Chief Executive Officer James Miller has characterized loan guarantees as "something we absolutely require." NRG announced last month it had selected reactor designs from Toshiba Corp.

The company wants to start construction on its new reactors, which could generate enough power for more than 2.1 million homes, by 2010. While NRG and other nuclear enthusiasts have predicted new reactors could come online by 2015, a March report from the nonpartisan Congressional Research Service predicted the process would take closer to 15 years to complete for several reasons, including the government's new review, testing and approval procedures.

Wind and solar make more electricity than nuclear for first time in UK

UK Renewables Surpass Nuclear Milestone as wind farms and solar panels outpace atomic output, cutting greenhouse gas emissions. BEIS data show low-carbon power generation rising while onshore wind subsidies and auction timelines face policy debate.

 

Key Points

It is the quarter when UK wind and solar generated more electricity than nuclear, signaling cleaner, low-carbon growth.

✅ BEIS reports wind and solar at 18.33 TWh vs nuclear 16.69 TWh

✅ Energy sector emissions fell 8% as coal use dropped

✅ Calls grow to reopen onshore wind support via CFD auctions

 

Wind farms and solar panels, with wind leading the power mix during key periods, produced more electricity than the UK’s eight nuclear power stations for the first time at the end of last year, official figures show.

Britain’s greenhouse gas emissions also continued to fall, dropping 3% in 2017, as coal use fell and the use of renewables climbed, though low-carbon generation stalled in 2019 according to later data.

Energy experienced the biggest drop in emissions of any UK sector, of 8%, while pollution from transport and businesses stayed flat.

Energy industry chiefs said the figures showed that the government should rethink its ban on onshore wind subsidies, a move that ministers have hinted could happen soon.

Lawrence Slade, chief executive of the big six lobby group Energy UK, said: “We need to keep up the pace ... by ensuring that the lowest cost renewables are no longer excluded from the market.”

Across the whole year, low-carbon sources of power – wind, solar, biomass and nuclear – provided a record 50.4% of electricity, up from 45.7% in 2016, when wind beat coal for the first time.

But in the fourth quarter of 2017, high wind speeds, new renewables installations and lower nuclear output saw wind and solar becoming the second biggest source of power for the first time.

Wind and solar generated 18.33 terawatt hours (TWh), with nuclear on 16.69TWh, and the UK later set a new record for wind power during 2019, the figures published by the Department for Business, Energy and Industrial Strategy show.

But renewables still have a long way to go to catch up with gas, the UK’s top source of electricity at 36.12TWh, which saw its share of generation fall slightly, though at times wind became the main source as capacity expanded.

Greenpeace said the figures showed the government should capitalise on its lead in renewables and “stop wasting time and money propping up nuclear power”.

Horizon Nuclear Power, a subsidiary of the Japanese conglomerate Hitachi, is in talks with Whitehall officials for a financial support package from the government, which it says it needs by midsummer.

By contrast, large-scale solar and onshore wind projects are not eligible for support, after the Conservative government cut subsidies in 2015.

However the energy minister, Claire Perry, recently told House Magazine that “we will have another auction that brings forward wind and solar, we just haven’t yet said when”.

Hydro One stock has too much political risk to recommend, Industrial Alliance says

Hydro One Avista merger faces regulatory scrutiny in Washington, Oregon, and Idaho, as political risk outweighs defensive utilities fundamentals like stable cash flow, rate base growth, EPS outlook, and a near 5% dividend yield.

 

Key Points

A planned Hydro One-Avista acquisition awaiting key state approvals amid elevated political and regulatory risk.

✅ Hold rating, $24 price target, 28.1% implied return

✅ EPS forecast: $1.27 in 2018; $1.38 in 2019

✅ Defensive utility: stable cash flow, 4-6% rate base growth

 

A seemingly positive development for Hydro One is overshadowed by ongoing political and regulatory risk, as seen after the CEO and board ouster, Industrial Alliance Securities analyst Jeremy Rosenfield says.

On October 4, staff from the Washington Utilities and Transportation Commission filed updated testimony in support of the merger of Hydro One and natural gas distributor Avista, which had previously received U.S. antitrust clearance from federal authorities.

The merger, which was announced in July of 2017 has received the green light from federal and key states, with Washington, Oregon and Idaho being exceptions, though the companies would later seek reconsideration from U.S. regulators in the process.

But Rosenfield says even though decisions from Oregon and Idaho are expected by December, there are still too many unknowns about Hydro One to recommend investors jump into the stock.

 

Hydro One stock defensive but risky

“We continue to view Hydro One as a fundamentally defensive investment, underpinned by (1) stable earnings and cash flows from its regulated utility businesses (2) healthy organic rate base and earning growth (4-6%/year through 2022) and (3) an attractive dividend (~5% yield, 70-80% target payout),” the analyst says. “In the meantime, and ahead of key regulatory approvals in the AVA transaction, we continue to see heightened political/regulatory risk as an overhand on the stock, outweighing Hydro One’s fundamentals in the near term.”

In a research update to clients today, Rosenfield maintained his “Hold” rating and one year price target of $24.00 on Hydro One, implying a return of 28.1 per cent at the time of publication.

Rosenfield thinks Hydro One will generate EPS of $1.27 per share in fiscal 2018, even though its Q2 profit plunged 23% as electricity revenue fell. He expects that number will improve to EPS of $1.38 a share the following year.

"Knowledge Gap" Is Contributing To On-the-job Electrical Injuries

BC Hydro Trades Electrical Safety addresses electric contact incidents among trade workers, emphasizing power line hazards, overhead lines clearance, the 3 m rule, jobsite planning, and safety training to prevent injuries during spring and summer.

 

Key Points

BC Hydro Trades Electrical Safety is guidance and training to reduce power-line contact risks for trade workers.

✅ Stay at least 3 m from overhead power lines and equipment

✅ Plan worksites and spot hazards before starting tasks

✅ Use BC Hydro electrical awareness training near electricity

 

A BC Hydro report finds serious electrical contact incidents are more common among trades workers, and research shows this is partly due to a knowledge gap in the electricity sector in Canada.

Trade workers were involved in more than 60 per cent of electric contact incidents that led to serious injuries over the last three years, according to BC Hydro.

One-in-five trade workers have also either made contact or had a close call with electric equipment.

A recent worksite electrocution case underscores the consequences of contact.

“New research finds many have had a close call with electricity on the job or have witnessed unsafe work near overhead lines or electrical equipment,” BC Hydro staff said in the report.

“A gap in electrical safety knowledge is a contributing factor in most of these incidents.”

Most electrical contact incidents take place in the spring and summer, when trade workers are working outdoors and are working in close proximity to power lines.

BC Hydro offered tips for trades workers who may work closely to possible electrical contact points:

  • Look up and down – Observe the site beforehand and plan work so you can avoid contact with power lines
  • Stay back – You and your tools should stay at least 3 m away from an overhead power line
  • Call for help – If you come across a fallen power line, or a tree branch or object contacts a line—stay back 10 metres and call 911. Never try and move it yourself. If you must work closer than 3 m to a power line at your worksite, call BC Hydro before you begin.
  • Learn about the risks – BC Hydro offers in-person and online electrical awareness training, such as arc flash training, for anyone who works near electricity.

The report found that 38 per cent of trades workers who participated in the report said they only feel “somewhat informed” about safety measures around working near electricity and 71 per cent were unable to identify the correct distance they should be away from active power lines or electrical equipment.

BC Hydro said trade workers should participate in its electrical awareness training courses, including arc flash training, to make sure all safety measures are taken.

New Mexico Could Reap $30 Billion Driving on Electricity

New Mexico EV Benefits highlight cheaper fuel, lower maintenance, cleaner air, and smarter charging, cutting utility bills, reducing NOx and carbon emissions, and leveraging incentives and renewable energy to accelerate EV adoption statewide.

 

Key Points

New Mexico EV Benefits are the cost, grid, and emissions gains from EV adoption and optimized off-peak charging.

✅ Electricity near $1.11 per gallon equivalent cuts fueling costs

✅ Fewer moving parts mean less maintenance and lifecycle costs

✅ Off-peak charging reduces utility bills and grid emissions

 

What would happen if New Mexicans ditched gasoline and started to drive on cleaner, cheaper electricity? A new report from MJ Bradley & Associates, commissioned by NRDC and Southwest Energy Efficiency Project, answers that question, demonstrating that New Mexico could realize $30 billion in avoided expenditures on gasoline and maintenance, reduced utility bills, and environmental benefits by 2050. The state is currently considering legislation to jump-start that transition by providing consumers incentives to support electric vehicle (EV) purchases and the installation of charging stations, drawing on examples like Nevada's clean-vehicle push to accelerate deployment, a policy that would require a few million dollars in lost tax revenue. The report shows an investment of this kind could yield tens of billions of dollars in net benefits.


$20 Billion in Driver Savings

EVs save families money because driving on electricity in New Mexico is the cost-equivalent of driving on $1.11 per gallon gasoline. Furthermore, EVs have fewer moving parts and less required maintenance—no oil changes, no transmissions, no mufflers, no timing belts, etc. That means that tackling the nation’s largest source of carbon pollution, transportation, could save New Mexicans over $20 billion by 2050 because EVs are cheaper to charge and maintain than gas powered cars, and an EV boom benefits all customers through lower rates.

Those are savings New Mexico can bank on because the price of electricity is significantly cheaper than the price of gasoline and also inherently more stable. Electricity is made from a diverse supply of domestic and increasingly clean resources, and 2021 electricity lessons continue to inform grid planning today. Unlike the volatile world oil market, New Mexico’s electric sector is regulated by the state’s utility commission. Adjusted for inflation, the price of electricity has been steady around the dollar-a-gallon equivalent mark in New Mexico for the last 20 years, while gas prices jump up or down radically and unpredictably.

$4.8 Billion in Reduced Electric Bills

While some warn that electric cars will challenge state power grids, New Mexico can charge millions of EVs without the need to make significant investments in the electric grid. This is because EVs can be charged when the grid is underutilized and renewable energy is abundant, like when people are sleeping overnight when wind energy generation often peaks. And the billions of dollars in new utility revenue from EV charging in excess of associated costs will be automatically returned to utility customers per an accounting mechanism that is already in state law that requires downward adjustment of rates when sales increase. Accordingly, widespread EV adoption could reduce every utility customer’s electric bill.

Thankfully, New Mexico’s electric industry is already acting to ensure utility customers in the state realize those benefits sooner rather than later. The state’s rural electric cooperatives have proposed an ambitious plan to leverage funds available as a result of the Volkswagen diesel scandal to build a state-wide public fast charging network that mirrors progress as Arizona goes EV across the Southwest. Additionally, New Mexico’s investor-owned utilities will soon propose transportation electrification investments as required by legislation NRDC supported last year that Governor Lujan Grisham signed into law.

$4.8 Billion in Societal Benefits from Reduced Pollution

The report estimates that widespread EV adoption would dramatically reduce emissions of greenhouse gases from passenger vehicles in New Mexico, and also cut emissions of NOx, a local pollutant that threatens the health off all New Mexicans, especially children and people with respiratory conditions. The report finds growing the state’s EV market to meet New Mexico’s long-term environmental goals would yield $4.8 billion in societal benefits.

The Bottom Line: New Mexico Should Act Now to Accelerate its EV Market

Adding it all up, that’s more than $30 billion in potential benefits to New Mexico by 2050. Here’s the catch: as of June 2019, there were only 2,500 EVs registered in New Mexico, which means the state needs to accelerate the EV market, as the American EV boom ramps up nationally, to capture those billions of dollars in potential benefits. Thankfully, with second generation, longer range, affordable EVs now available, the market is well positioned to expand rapidly as the state moves to adopt Clean Car Standards that will ensure EVs are available for purchase in the state.

Getting it right

New Mexico has enormous amounts to gain from a small investment in incentives that support EV adoption now. For that investment to pay off, it needs to send a clear and unambiguous signal. Unfortunately, the same legislation that would establish tax credits to increase consumer access to electric vehicles in New Mexico was recently amended so it would not be helpful for 80 percent of consumers who lease, instead of buying EVs. And it would penalize EV drivers at the same time—with a $100 annual increase in registration fees, even as Texas adds a $200 EV fee under a similar rationale, to make up for lost gas tax revenue. That’s significantly more than what drivers of new gasoline vehicles pay annually in gas taxes in the state. Consumer Reports recently analyzed the growing trend to unfairly penalize electric cars via disproportionately high registration fees. In doing so, it estimated that the “maximum justifiable fee” to replace gas tax revenue in New Mexico would be $53. Anything higher will only slow or stop benefits New Mexico can attain from moving to cleaner cars.

To be clear, everyone should pay their fair share to maintain the transportation system, but EVs are not the problem when it comes to lost gas tax revenue. We need a comprehensive solution that addresses the real sources of transportation revenue loss while not undermining efforts to reduce dependence on gasoline. Thankfully, that can be done.

Is this the start of an aviation revolution?

Harbour Air Electric Seaplanes pioneer sustainable aviation with battery-electric propulsion, zero-emission operations, and retrofitted de Havilland Beavers using magniX motors for regional commuter routes, cutting fuel burn, maintenance, and carbon footprints across British Columbia.

 

Key Points

Retrofitted floatplanes using magniX battery-electric motors to provide zero-emission, short-haul regional flights.

✅ Battery-electric magniX motors retrofit de Havilland DHC-2 Beavers

✅ Zero-emission, low-noise operations on short regional routes

✅ Lower maintenance and operating costs vs combustion engines

 

Aviation is one of the fastest rising sources of carbon emissions from transport, but can a small Canadian airline show the industry a way of flying that is better for the planet?

As air journeys go, it was just a short hop into the early morning sky before the de Havilland seaplane splashed back down on the Fraser River in Richmond, British Columbia. Four minutes earlier it had taken off from the same patch of water. But despite its brief duration, the flight may have marked the start of an aviation revolution.

Those keen of hearing at the riverside on that cold December morning might have been able to pick up something different amid the rumble of the propellers and whoosh of water as the six-passenger de Havilland DHC-2 Beaver took off and landed. What was missing was the throaty growl of the aircraft’s nine-cylinder radial engine.

In its place was an all-electric propulsion engine built by the technology firm magniX that had been installed in the aircraft over the course of several months. The four-minute test flight (the plane was restricted to flying in clear skies, so with fog and rain closing in the team opted for a short trip) was the first time an all-electric commercial passenger aircraft had taken to the skies.

“It was the first shot of the electric aviation revolution,” says Roei Ganzarski, chief executive of magniX, which worked with Canadian airline Harbour Air Seaplanes to convert one of the aircraft in their fleet of seaplanes so it could run on battery power rather than fossil fuels.

For Greg McDougall, founder of Harbour Air and pilot during the test flight, it marked the culmination of years of trying to put the environment at the forefront of its operations, backed by research investment across the program.

Harbour Air, which has a fleet of some 40 commuter floatplanes serving the coastal regions around Vancouver, Victoria and Seattle, was the first airline in North America to become carbon-neutral through offsets in 2007. A one-acre green roof on their new Victoria airline terminal followed. Then in 2017, 50 solar panels and four beehives housing 10,000 honeybees were added, but for McDougall, a Tesla owner with an interest in disruptive technology, the big goal was to electrify the fleet, with 2023 electric passenger flights as an early target for service.

McDougall searched for alternative motor options for a couple of years and had put the plan on the backburner when Ganzarski first approached him in February 2019. “He said, ‘We’ve got a motor we want to get certified and we want to fly it before the end of the year,’” McDougall recalls.

The two companies found their environmental values and teams were a good match and quickly formed a partnership. Eleven months later, the modest Canadian airline got what McDougall refers to as their “e-plane” off the ground, pulling ahead of other electric flight projects, including those by big-name companies Airbus, Boeing and Rolls-Royce, and startups such as Eviation that later stumbled.

The project came together in record time considering how risk-adverse the aviation industry is, says McDougall. “Someone had to take the lead,” he says. “The reason I live in British Columbia is because of the outdoors: protecting it is in our DNA. When it came to getting the benefits from electric flight it made sense for us to step in and pioneer the next step.”

As the threat posed by the climate crisis deepens, there has been renewed interest in developing electric passenger aircraft as a way of reducing emissions
Electric flight has been around since the 1970s, but it’s remained limited to light-weight experimental planes flying short distances and solar-powered aircraft with enormous wingspans yet incapable of carrying passengers. But as the threat posed by the climate crisis deepens, there has been renewed interest in developing electric passenger aircraft as a way of reducing emissions and airline operating costs, aligning with broader Canada-U.S. collaboration on electrification across transport.

Currently there are about 170 electric aircraft projects underway internationally –up by 50% since April 2018, according to the consulting firm Roland Berger. Many of the projects are futuristic designs aimed at developing urban air taxis, private planes or aircraft for package delivery. But major firms such as Airbus have also announced plans to electrify their own aircraft. It plans to send its E-Fan X hybrid prototype of a commercial passenger jet on its maiden flight by 2021. But only one of the aircraft’s four jet engines will be replaced with a 2MW electric motor powered by an onboard battery.

This makes Harbour Air something of an outlier. As a coastal commuter airline, it operates smaller floatplanes that tend to make short trips up and down the coastline of British Columbia and Washington State, which means its aircraft can regularly recharge their batteries after a point-to-point electric flight along these routes. The company sees itself in a position to retrofit its entire fleet of floatplanes and make air travel in the region as green as possible.

This could bring some advantages. The efficiency of a typical combustion engine for a plane like this is fairly low – a large proportion of the energy from the fuel is lost as waste heat as it turns the propeller that drives the aircraft forward. Electrical motors have fewer moving parts, meaning there’s less maintenance and less maintenance cost, and comparable benefits are emerging for electric ships operating on the B.C. coast as well.

Electrical motors have fewer moving parts, meaning there’s less maintenance and less maintenance cost
Erika Holtz, Harbour Air’s engineering and quality manager, sees the move to electric as the next major aviation advancement, but warns that one stumbling block has been the perception of safety. “Mechanical systems are much better known and trusted,” she says. In contrast people see electrical systems as a bit unknown – think of your home computer. “Turning it off and on again isn’t an option in aviation,” she adds.

But it’s the possibility of spurring lasting change in aviation that’s made working on the Harbour Air/magniX project so exciting for Holtz. Aviation technology has stagnated over the past decades, she says. “Although there have been incremental improvements in certain technologies, there hasn't been a major development change in aviation in 50 years.”

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.
