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.

Germany's Coal Reliance reflects an energy crisis, soaring natural gas prices, and a nuclear phase-out, as Destatis data show higher coal-fired electricity despite growing wind and solar generation, impacting grid stability and emissions.

Key Points

Germany's coal reliance is more coal power due to gas spikes and a nuclear phase-out, despite wind and solar growth.

✅ Coal share near one-third of electricity, per Destatis

✅ Gas-fired output falls as prices soar after Russia's invasion

✅ Wind and solar rise; grid stability and recession risks persist

Germany is relying on highly-polluting coal for almost a third of its electricity, as the impact of government policies, reflecting an energy balancing act for the power sector, and the war in Ukraine leads producers in Europe’s largest economy to use less gas and nuclear energy.

In the first six months of the year, Germany generated 82.6 kWh of electricity from coal, up 17 per cent from the same period last year, according to data from Destatis, the national statistics office, published on Wednesday. The leap means almost one-third of German electricity generation now comes from coal-fired plants, up from 27 per cent last year. Production from natural gas, which has tripled in price to €235 per megawatt hour since Russia’s invasion in late February, fell 18 per cent to only 11.7 per cent of total generation.

Destatis said that the shift from gas to coal was sharper in the second quarter. Coal-fired electricity increased by an annual rate of 23 per cent in the three months to June, while electricity generation from natural gas fell 19 per cent.

The figures highlight the challenge facing European governments in meeting clean energy goals after the Kremlin announced this week that the Nordstream 1 pipeline that takes Russian gas to Germany would remain closed until Europe removed sanctions on the country’s oil.

Germany has been trying to reduce its reliance on coal, which releases almost twice as many emissions as gas and more than 60 times those of nuclear energy, according to estimates from the Intergovernmental Panel on Climate Change, though grid expansion challenges have slowed renewable build-out in recent years.

Chancellor Olaf Scholz said the opposition CDU bore “complete responsibility” for the exit from coal and nuclear power that formed part of his predecessor Angela Merkel’s Energiewende policies, amid a continuing nuclear option debate in climate policy, which in turn raised reliance on Russian gas. At the beginning of this year, more than 50 per cent of Germany’s gas imports came from Russia, a figure that fell slightly over the opening half of 2022.

But CDU leader Friedrich Merz accused the government of “madness” over its decision to idle the country’s three remaining nuclear power stations from the end of this year, though officials have argued that nuclear would do little to solve the gas issue in the short term.

Electricity generation from nuclear energy has already halved after three of the six nuclear power plants that were still in operation at the end of 2021 were closed during the first half of this year. Berlin said on Monday it would keep on standby two of its remaining three nuclear power stations, a move to extend nuclear power during the energy crisis, which were all due to close at the end of the year.

The German government has warned of the risk of electricity shortages this winter. “We cannot be sure that, in the event of grid bottlenecks in neighbouring countries, there will be enough power plants available to help stabilise our electricity grid in the short term,” said German economy minister Robert Habeck on Monday.

However Scholz said that, after raising gas storage levels to 86 per cent of capacity, Germany would “probably get through this winter, despite all the tension”.

One bright spot from the data was the increase in use of renewable energy, highlighting a recent renewables milestone in Germany. The proportion of electricity generated from wind power generation rose by 18 per cent to 25 per cent of all electricity generation, while solar energy production increased 20 per cent.

Ángel Talavera, head of Europe economics at the consultancy Oxford Economics, said that the success in moving away from gas towards other energy sources “means that the risks of hard energy rationing over the winter are less severe now, even with little to no Russian gas flows”.

However, economists still expect a recession in the eurozone’s largest economy, amid a deteriorating German economy outlook over the near term, as a large part of the impact comes via higher prices and because industries and households still rely on gas for heating.

Separate official data also published on Wednesday showed that German industrial production slid 0.3 per cent between June and July. Production at Germany’s most energy intensive industries fell almost 7 per cent in the five months after Russia’s invasion of Ukraine.

“The demand destruction caused by the surge in prices will still send the German economy into recession over the winter,” said Talavera.

Georgia Power June bill credit delivers PSC-approved savings, lower fuel rates, and COVID-19 relief for residential customers, driven by natural gas prices and 2018 earnings, with typical 1,000 kWh users seeing June bill reductions.

Key Points

A PSC-approved one-time credit and lower fuel rates reducing June bills for Georgia Power residential customers.

✅ $11.29 credit for 1,000 kWh usage on June bills

✅ Fuel rate cut saves $10.26 per month from June to September 2020

✅ PSC-approved $51.5M credit based on Georgia Power's 2018 results

Georgia Power announced that the typical residential customer using 1,000-kilowatt hours will receive an $11.29 credit on their June bill, reflecting a lump-sum credit model also used elsewhere.

This reflects implementation of a one-time $51.5 million credit for customers, similar to Gulf Power's bill decrease efforts, approved by the Georgia Public Service Commission, as a result of

Georgia Power's 2018 financial results.

Pairing the June credit with new, lower fuel rates recently announced, the typical residential customer would see a reduction of $21.55 in June, even as some regions face increases like Pennsylvania's winter price hikes elsewhere.

The amount each customer receives will vary based on their 2018 usage. Georgia Power will apply the credit to June bills for customers who had active accounts as of Dec. 31, 2018, and are still active or receiving a final bill as of June 2020, and the company has issued pandemic scam warnings to help customers stay informed.

Fuel rate lowered 17.2 percent

In addition to the approved one-time credit in June, the Georgia PSC recently approved Georgia Power’s plan to reduce its fuel rates by 17.2 percent and total billings by approximately $740 million over a two-year period. The implementation of a special interim reduction will provide customers additional relief during the COVID-19 pandemic through even lower fuel rates over the upcoming 2020 summer months. The lower fuel rate and special interim reduction will lower the total bill of a typical residential customer using an average of 1,000-kilowatt hours by a total of $10.26 per month from June through September 2020.

The reduction in the company’s fuel rate is driven primarily by lower natural gas prices, even as FPL proposed multiyear rate hikes in Florida, as a result of increased natural gas supplies, which the company is able to take advantage of to benefit customers due to its diverse generation sources.

February bill credit due to tax law savings

Georgia Power completed earlier this year the third and final bill credit associated with the Tax Cuts and Jobs Act of 2017, resulting in credits totaling $106 million. The typical residential customer using an average of 1,000 kilowatt-hours per month received a credit of approximately $22 on their February Georgia Power bill, a helpful offset as U.S. electric bills rose 5% in 2022 according to national data.

Smart grids, renewable electricity generation, automation, carbon capture and storage, and electric vehicles are transforming the traditional electricity industry. Technological innovation is reshaping and reinventing the skills and occupations required to support the electrical grid of the 21st century, even as pandemic-related grid warnings underscore resilience needs.

Canada has been a global leader in embracing and capitalizing on drivers of disruption and will continue to navigate the rapidly changing landscape of electricity by rethinking and reshaping traditional occupational standards and skills profiles.

In an effort to proactively address the needs of our current and future labour market, building on regional efforts like Nova Scotia energy training to enhance participation, Electricity Human Resources Canada (EHRC) is pleased to announce the launch of funding for the new National Occupational Standards (NOS) and Career Portal project. This project will explore the transformational impact of technology, digitalization and innovation on the changing nature of work in the sector.

Through this research a total of 15 National Occupational Standards and Essential Skills Profiles will be revised or developed to better prepare jobseekers, including young Canadians interested in electricity to transition into the electricity sector. Occupations to be covered include:

• Electrical Engineering Technician/ Technologist

• Power Protection and Control Technician/ Technologist

• Power Systems Operator

• Solar Photovoltaic Installer

• Power Station Operator

• Wind Turbine Technician

• Geothermal Heat Pump Installer

• Solar Thermal Installer

• Utilities Project Manager

• Heat Pump Designer

• Small System Designer (Solar)

• Energy Storage Technician

• Smart Grid Specialist

• 2 additional occupations TBD

The labour market intelligence gathered during the research will examine current occupations or job functions facing change or requiring re-skilling or up-skilling, including specialized courses such as arc flash training in Vancouver that bolster safety competencies, as well as entirely emerging occupations that will require specialized skills.

This project is funded in part by the Government of Canada’ Sectoral Initiative Program and supports its goal to address current and future skills shortages through the development and distribution of sector-specific labour market information.

“Canada’s workforce must evolve with the changing economy. This is critical to building the middle class and ensuring continued economic growth. Our government is committed to an evidence-based approach and is focused on helping workers to gain valuable work experience and the skills they need for a fair chance at success. By collaborating with partners like Electricity Human Resources Canada, we can ensure that we are empowering workers today, and planning for the jobs of tomorrow.” – The Honourable Patty Hajdu, Minister of Employment, Workforce Development and Labour

“By encouraging the adoption of new technologies and putting in place the appropriate support for workers, Canada can minimize both skills shortages and technological unemployment. A long-term strategic and national approach to human resource planning and training is therefore critical to ensuring that we continue to maintain the level of growth, reliability, safety and productivity in the system – with a workforce that is truly inclusive and diverse.” – Michelle Branigan, CEO, EHRC.

“The accelerated pace of change in our sector, including advancements in technology and innovation will also have a huge impact on our workforce. We need to anticipate what those impacts will be so employers, employees and job seekers alike can respond to the changing structure of the sector and future job opportunities.” – Jim Kellett, Board Chair, EHRC.

Ontario Comprehensive Electricity Plan delivers Global Adjustment reductions for industrial and commercial non-RPP customers, lowering electricity rates, shifting renewable energy costs, and enhancing competitiveness across Ontario businesses in 2022, with additional 4 percent savings.

Key Points

Ontario's plan lowers Global Adjustment by shifting renewable costs, cutting industrial and commercial bills 15-17%.

✅ Shifts above-market non-hydro renewable costs to the Province

✅ Reduces GA for industrial and commercial non-RPP customers

✅ Additional 4% savings on 2022 bills after GA deferral

As of January 1, 2022, industrial and commercial electricity customers will benefit from the full savings introduced through the Ontario government’s Comprehensive Electricity Plan, which supports stable electricity pricing for industrial and commercial companies, announced in Budget 2020, and first implemented in January 2021. This year customers could see an additional four percent savings compared to their bills last year, bringing the full savings from the Comprehensive Electricity Plan to between 15 and 17 per cent, making Ontario a more competitive place to do business.

“Our Comprehensive Electricity Plan has helped reverse the trend of skyrocketing electricity prices that drove jobs out of Ontario,” said Todd Smith, Minister of Energy. “Over 50,000 customers are benefiting from our government’s plan which has reduced electricity rates on clean and reliable power, allowing them to focus on reinvesting in their operations and creating jobs here at home.”

Starting on January 1, 2021, the Comprehensive Electricity Plan reduced overall Global Adjustment (GA) costs for industrial and commercial customers who do not participate in the Regulated Price Plan (RPP) by shifting the forecast above-market costs of non-hydro renewable energy, such as wind, solar and bioenergy, from the rate base to the Province, alongside energy-efficiency programs that complement demand reduction efforts.

“Since taking office, our government has listened to job creators and worked to lower the costs of doing business in the province. Through these significant reductions in electricity prices through the Comprehensive Electricity Plan, customers all across Ontario will benefit from significant savings in their business operations in 2022,” said Vic Fedeli, Minister of Economic Development, Job Creation and Trade. “By continuing to reduce electricity costs, lowering taxes, and cutting red tape our government has reduced the cost of doing business in Ontario by nearly $7 billion annually to ensure that we remain competitive, innovative and poised for economic recovery.”

As part of its COVID response, including electricity relief for families and small businesses, Ontario had deferred a portion of GA between April and June 2020 for industrial and non-RPP commercial customers, with more than 50,000 customers benefiting. Those same businesses paid back these deferred GA costs over 12 months, between January 2021 and December 2021, while the province prepared to extend disconnect moratoriums for residential customers.

During the pandemic, residential electricity use rose even as overall consumption dropped, underscoring shifts in load patterns.

Now that the GA deferral repayment period is over, industrial and non-RPP commercial customers will benefit from the full cost reductions provided to them by the Comprehensive Electricity Plan, alongside temporary off-peak rate relief that supported families and small businesses. This means that, beginning January 1, 2022, these businesses could see an additional four per cent savings on their bills compared to 2021, as new ultra-low overnight pricing options emerge depending on their location and consumption.
