Helping dairy farmers reduce emissions

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

Key Points

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

✅ Nanopores drive charge separation from ambient water molecules

✅ Works across materials: silicon, wood, bacterial films

✅ Predictable, continuous power unlike intermittent solar or wind

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

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

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

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

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

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

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

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

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

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

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

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.

EU Electricity Market Reform CFDs seek stable prices via contracts for difference, balancing renewables and nuclear, shielding consumers, and boosting competitiveness as France and Germany clash over scope, grid expansion, and hydrogen production.

Key Points

EU framework using contracts for difference to stabilize power prices, support renewables and nuclear, and protect users.

✅ Guarantees strike prices for new low-carbon generation

✅ Balances consumer protection with industrial competitiveness

✅ Disputed scope: nuclear inclusion, grids, hydrogen eligibility

Despite record temperatures this October, Europe is slowly shifting towards winter - its second since the Ukraine war started and prompted Russia to cut gas supplies to the continent amid an energy crisis that has reshaped policy.

After prices surged last winter, when gas and electricity bills “nearly doubled in all EU capitals”, the EU decided to take emergency measures to limit prices.

In March, the European Commission proposed a reform to revamp the electricity market “to boost renewables, better protect consumers and enhance industrial competitiveness”.

However, France and Germany are struggling to find a compromise as rolling back prices is tougher than it appears and the clock is ticking as European energy ministers prepare to meet on 17 October in Luxembourg.

The controversy around CFDs
At the heart of the issue are contracts for difference (CFDs).

By providing a guaranteed price for electricity, CFDs aim to support investment in renewable energy projects.

France - having 56 nuclear reactors - is lobbying for nuclear energy to be included in the CFDs, but this has caught the withering eye of Germany.

Berlin suspects Paris of wanting an exception that would give its industry a competitive advantage and plead that it should only apply to new investments.

France wants ‘to regain control of the price’
The disagreement is at the heart of the bilateral talks in Hamburg, which started on Monday, between the French and German governments.

French President Emmanuel Macron promised “to regain control of the price of electricity, at the French and European level” and outlined a new pricing scheme in a speech at the end of September.

As gas electricity is much more expensive than nuclear electricity, France might be tempted to switch to a national system rather than a European one after a deal with EDF on prices to be more competitive economically.

However, France is "confident" that it will reach an agreement with Germany on electricity market reforms, Macron said on Friday.

Siding with France are other pro-nuclear countries such as Hungary, the Czech Republic and Poland, while Germany can count on the support of Austria, Luxembourg, Belgium and Italy amid opposition from nine EU countries to treating market reforms as a price fix.

But even if a last-minute agreement is reached, the two countries’ struggles over energy are creeping into all current European negotiations on the subject.

Germany wants a massive extension of electricity grids on the continent so that it can import energy; France is banking on energy sovereignty and national production.

France wants to be able to use nuclear energy to produce clean hydrogen, while Germany is reluctant, and so on.

eRex Biomass Power Plant will deliver 300 MW in Japan, offering stable baseload renewable energy, coal-cost parity, and feed-in tariff independence through economies of scale, efficient fuel procurement, and utility-scale operations supporting RE100 demand.

Key Points

A 300 MW Japan biomass project targeting coal-cost parity and FIT-free, stable baseload renewable power.

✅ 300 MW capacity; enough for about 700,000 households

✅ Aims to skip feed-in tariff via economies of scale

✅ Targets coal-cost parity with stable, dispatchable output

Power supplier eRex will build its largest biomass power plant to date in Japan, hoping the facility's scale will provide healthy margins, a strategy increasingly seen among renewable developers pursuing diverse energy sources, and a means of skipping the government's feed-in tariff program.

The Tokyo-based electric company is in the process of selecting a location, most likely in eastern Japan. It aims to open the plant around 2024 or 2025 following a feasibility study. The facility will cost an estimated 90 billion yen ($812 million) or so, and have an output of 300 megawatts -- enough to supply about 700,000 households. ERex may work with a regional utility or other partner

The biggest biomass power plant operating in Japan currently has an output of 100 MW. With roughly triple that output, the new facility will rank among the world's largest, reflecting momentum toward 100% renewable energy globally that is shaping investment decisions.

Nearly all biomass power facilities in Japan sell their output through the government-mediated feed-in tariff program, which requires utilities to buy renewable energy at a fixed price. For large biomass plants that burn wood or agricultural waste, the rate is set at 21 yen per kilowatt-hour. But the program costs the Japanese public more than 2 trillion yen a year, and is said to hamper price competition.

ERex aims to forgo the feed-in tariff with its new plant by reaping economies of scale in operation and fuel procurement. The goal is to make the undertaking as economical as coal energy, which costs around 12 yen per kilowatt-hour, even as solar's rise in the U.S. underscores evolving benchmarks for competitive renewables.

Much of the renewable energy available in Japan is solar power, which fluctuates widely according to weather conditions, though power prediction accuracy has improved at Japanese PV projects. Biomass plants, which use such materials as wood chips and palm kernel shells as fuel, offer a more stable alternative.

Demand for reliable sources of renewable energy is on the rise in the business world, as shown by the RE100 initiative, in which 100 of the world's biggest companies, such as Olympus, have announced their commitment to get 100% of their power from renewable sources. ERex's new facility may spur competition.

Generation Impact Report reveals how Canada's electricity sector can recruit Millennials and Gen Z, highlighting workforce gaps, career pathways, innovative projects, secure pay, and renewable energy opportunities to attract young talent nationwide.

Key Points

An EHRC survey on youth views of electricity careers and recruitment strategies to build a skilled workforce.

✅ Surveyed 1,500 Canadians aged 18-36 nationwide

✅ Highlights barriers: low awareness of sector roles

✅ Emphasizes fulfilling work, secure pay, innovation

Young Canadians make up far less of the electricity workforce than other sectors, says Electricity Human Resources Canada, as noted in an EHRC investment announcement that highlights sector priorities, and its latest report aims to answer the question “Why?”.

The report, “Generation Impact: Future Workforce Perspectives”, was based on a survey of 1500 respondents across Canada between the ages of 18 and 36. This cohort’s perspectives on the electricity sector were mostly Positive or Neutral, and that Millennial and Gen Z Canadians are largely open to considering careers in electricity, especially as initiatives such as a Nova Scotia energy training program expand access.

The biggest barrier is a knowledge gap in electrical safety that limits awareness of the opportunities available.

To an industry looking to develop a pipeline of young talent, “Generation Impact” reveals opportunities for recruitment; key factors that Millennial and Gen Z Canadians seek in their ideal careers include fulfilling work, secure pay and the chance to be involved in innovative projects, including specialized arc flash training in Vancouver opportunities that build expertise.

“The electricity sector is already home to the kinds of fulfilling and innovative careers that many in the Millennial and Gen Z cohorts are looking for,” said Michelle Branigan, CEO of EHRC. “Now it’s just a matter of communicating effectively about the opportunities and benefits, including leadership in worker safety initiatives, our sector can offer.”

“Engaging young workers in Canada’s electricity sector is critical for developing the resiliency and innovation needed to support the transformation of Canada’s energy future, especially as working from home drives up electricity bills and reshapes demand,” said Seamus O’Regan, Canada’s Minister of Natural Resources. “The insights of this report will help to position the sector competitively to leverage the talent and skills of young Canadians.”

“Generation Impact” was funded in part by the Government of Canada’s Student Work Placement Program and Natural Resources Canada’s Emerging Renewable Power Program, in a context of rising residential electricity use that underscores workforce needs.

California Net Zero Grid Investment will fuel electrification, renewable energy buildout, EV adoption, and grid modernization, boosting utilities, solar, and storage, while policy, IRA incentives, and transmission upgrades drive reliability and long-term rate base growth.

Key Points

Funding to electrify sectors and modernize the grid, scaling renewables, EVs, and storage to meet 2045 net zero goals.

✅ $370B over 22 years to meet 2045 net zero target

✅ Utilities lead gains via grid modernization and rate base growth

✅ EVs, solar, storage scale; IRA credits offset costs

$370 billion: That’s the investment Edison International CEO Pedro Pizarro says is needed for California’s power grid to meet the state’s “net zero” goal for CO2 emissions by 2045.

Getting there will require replacing fossil fuels with electricity in transportation, HVAC systems for buildings and industrial processes. Combined with population growth and data demand potentially augmented by artificial intelligence, that adds up to an 82 percent increase in electricity demand over 22 years, or 3 percent annually, and a potential looming shortage if buildout lags.

California’s plans also call for phasing out fossil fuel generation in the state, despite ongoing dependence on fossil power during peaks. And presumably, its last nuclear plant—PG&E Corp’s (PCG) Diablo Canyon—will be eventually be shuttered as well. So getting there also means trebling the state’s renewable energy generation and doubling usage of rooftop solar.

Assuming this investment is made, it’s relatively easy to put together a list of beneficiaries. Electric vehicles hit 20 percent market share in the state in Q2, even as pandemic-era demand shifts complicate load forecasting. And while competition from manufacturers has increased, leading manufacturers like Tesla TSLA -3% Inc (TSLA) can look forward to rising sales for some time—though that’s more than priced in for Elon Musk’s company at 65 times expected next 12 months earnings.

In the past year, California regulators have dialed back net metering through pricing changes affecting compensation, a subsidy previously paying rooftop solar owners premium prices for power sold back to the grid. That’s hit share prices of SunPower Corp (SPWR) and Sunrun Inc (RUN) quite hard, by further undermining business plans yet to demonstrate consistent profitability.

Nonetheless, these companies too can expect robust sales growth, as global prices for solar components drop and Inflation Reduction Act tax credits at least somewhat offset higher interest rates. And the combination of IRA tax credits and U.S. tariff walls will continue to boost sales at solar manufacturers like JinkoSolar Holding (JKS).

The surest, biggest beneficiaries of California’s drive to Net Zero are the utilities, reflecting broader utility trends in grid modernization, with investment increasing earnings and dividends. And as the state’s largest pure electric company, Edison has the clearest path.

Edison is currently requesting California regulators OK recovery over a 30-year period of $2.4 billion in losses related to 2017 wildfires. Assuming a amicable decision by early next year, management can then turn its attention to upgrading the grid. That investment is expected to generate long-term rate base growth of 8 percent at year, fueling 5 to 7 percent annual earnings growth through 2028 with commensurate dividend increases.

That’s a strong value proposition Edison stock, with trades at just 14 times expected next 12 months earnings. The yield of roughly 4.4 percent at current prices was increased 5.4 percent this year and is headed for a similar boost in December.

When California deregulated electricity in 1996, it required utilities with rare exceptions to divest their power generation. As a result, Edison’s growth opportunity is 100 percent upgrading its transmission and distribution grid. And its projects can typically be proposed, sited, permitted and built in less than a year, limiting risk of cost overruns to ensure regulatory approval and strong investment returns.

Edison’s investment plan is also pretty much immune to an unlikely backtracking on Net Zero goals by the state. And the company has a cost argument as well: Dr Pizarro cites U.S. Department of Energy and Department of Transportation data to project inflation-adjusted savings of 40 percent in California’s total customer energy bills from full electrification.

There’s even a reason to believe 40 percent savings will prove conservative. Mainly, gasoline currently accounts for a bit more than half energy expenditures. And after a more than 10-year global oil and gas investment drought, supplies are likely get tighter and prices possibly much higher in coming years.

Of course, those savings will only show up after significant investment is made. At this point, no major utility system in the world runs on 100 percent renewable energy, and California’s blackout politics underscore how reliability concerns shape deployment. And the magnitude of storage technology needed to overcome intermittency in solar and wind generation is not currently available let alone affordable, though both cost and efficiency are advancing.

Taking EVs from 20 to 100 percent of California’s new vehicle sales calls for a similar leap in efficiency and cost, even with generous federal and state subsidy. And while technology to fully electrify buildings and homes is there, economically retrofitting statewide is almost certainly going to be a slog.

At the end of the day, political will is likely to be as important as future technological advance for how much of Pizarro’s $370 billion actually gets spent. And the same will be true across the U.S., with state governments and regulators still by and large calling the shots for how electricity gets generated, transmitted and distributed—as well as who pays for it and how much, even as California’s exported policies influence Western markets.

Ironically, the one state where investors don’t need to worry about renewable energy’s prospects is one of the currently reddest politically. That’s Florida, where NextEra Energy NEE +2.8% (NEE) and other utilities can dramatically cut costs to customers and boost reliability by deploying solar and energy storage.

You won’t hear management asserting it can run the Sunshine State on 100 percent renewable energy, as utilities and regulators do in some of the bluer parts of the country. But by demonstrating the cost and reliability argument for solar deployment, NextEra is also making the case why its stock is America’s highest percentage bet on renewables’ growth—particularly at a time when all things energy are unfortunately becoming increasingly, intensely political.
