Rising fuel prices are zapping Nova Scotia Power's pocketbook and are behind the utility's latest application to hike rates.
Volatile world petroleum costs are impacting the price of fuel and putting pressure on the bottom line, suggested Rob Bennett, Nova Scotia Power's new president and chief executive officer.
"It's obvious that we need to recover these real costs we incur in the process of producing electricity for Nova Scotians and that's what the upcoming rate hearing is all about," he said during a speech to Bridgewater-area business leaders.
The Nova Scotia Utility and Review Board will hear Nova Scotia Power's request for a 12.1 per cent rate hike on September 15. The increase would become effective by January 1, 2009.
The company is producing multi-million-dollar profits but feels customers will be understanding of their request.
"The company has performed very well in the first half of this year but we will really need that momentum to carry us through to an average year's performance by the end of 2008 and that's primarily because we're seeing the impact of increasing fuel costs now in our business," he told this newspaper after his address.
"Nobody wants to see rates go up. Nobody is happy when prices increase but certainly people recognize that the cost of fuel in the world as we know it today has changed dramatically."
Seven weeks into his new position, Mr. Bennett has been speaking to chambers of commerce about the challenges ahead facing Nova Scotia Power. One of the steepest learning curves for him has been getting used to the public profile this latest rate hearing has assumed.
He said the utility wants to be fair and open to its customers and shareholders and be effective in the long term. That's where Mr. Bennett feels wind energy "holds the most immediate promise" with its accessibility and competitive pricing.
They are also eyeing the Bay of Fundy for tidal generation.
Mr. Bennett said to look for Nova Scotia Power to take the lead in helping its customers save money by using less electricity.
"The most important thing that I can reinforce with customers is the importance of conservation and energy efficiency," he said.
Philippines Nuclear Energy Policy aims to add nuclear power to the energy mix via executive order, meeting rising electricity demand with 24/7 baseload while balancing safety, renewables, and imported fuel dependence in the Philippines.
Key Points
A government plan to include nuclear power in the energy mix to meet demand, ensure baseload, and uphold safety.
✅ Executive order proposed by Energy Secretary Alfonso Cusi
✅ Balances safety, renewables, and energy security
Phillipines Presidential spokesman Salvador Panelo said Energy Secretary Alfonso Cusi made the proposal during last Monday's Cabinet meeting in Malacaaang. "Secretary Cusi likewise sought the approval of the issuance of a proposed executive order for the inclusion of nuclear power, including next-gen nuclear options in the country's energy mix as the Philippines is expected to the rapid growth in electricity and electricity demand, in which, 24/7 power is essential and necessary," Panelo said in a statement.
Panelo said Duterte would study the energy chief's proposal, as China's nuclear development underscores regional momentum. In the 1960s until the mid 80s, the late president Ferdinand Marcos adopted a nuclear energy program and built the Bataan Nuclear Plant.
The nuclear plant was mothballed after Corazon Aquino became president in 1986. There have been calls to revive the nuclear plant, saying it would help address the Philippines' energy supply issues. Some groups, however, said such move would be expensive and would endanger the lives of people living near the facility, citing Three Mile Island as a cautionary example.
Panelo said proposals to revive the Bataan Nuclear Plant were not discussed during the Cabinet meeting, even as debates like California's renewable classification continue to shape perceptions. Indigenous energy sources natural gas, hydro, coal, oil, geothermal, wind, solar, biomassand ethanol constitute more than half or 59.6%of the Philippines' energy mix.
Imported oil make up 31.7% while imported coal, reflecting the country's coal dependency, contribute about 8.7%.
In 2018, Duterte said safety should be the priority when deciding whether to tap nuclear energy for the country's power needs, as countries like India's nuclear restart proceed with their own safeguards.
Iran Combined-Cycle Power Plants drive energy efficiency, cut greenhouse gases, and expand megawatt capacity by converting thermal units; MAPNA-led upgrades boost grid reliability, reduce fuel use, and accelerate electricity generation growth nationwide.
Key Points
Upgraded thermal plants that reuse waste heat to boost efficiency, cut emissions, and add capacity to Iran's grid.
✅ 27 thermal plants converted; 160 more viable units identified
✅ Adds 12,600 MW capacity via heat recovery steam generators
✅ Combined-cycle share: 31.2% of 80.509 GW capacity
Iran has turned six percent of its thermal power plans into combined cycle plants in order to reduce greenhouse gases and save energy, with potential to lift thermal plants' PLF under rising demand, IRNA reported, quoting an energy official.
According to the MAPNA Group’s Managing Director Abbas Aliabadi, so far 27 thermal power plants have been converted to combined-cycle ones, aligning with Iran’s push to transmit power to Europe as a regional hub.
“The conversion of a thermal power plant to a combined cycle one takes about one to two years, however, it is possible for us to convert all the country’s thermal power plants into combined cycle plants over a five-year period.
Currently, a total of 478 thermal power plants are operating throughout Iran, of which 160 units could be turned into combined cycle plants. In doing so, 12,600 megawatts will be added to the country’s power capacity, supporting ongoing exports such as supplying a large share of Iraq's electricity under existing arrangements.
As reported by IRNA on Wednesday, Iran’s Nominal electricity generation capacity has reached 80,509 megawatts (80.509 gigawatts), and it is deepening energy cooperation with Iraq to bolster regional reliability. The country increased its electricity generation capacity by 500 megawatts (MW) compared to the last year (ended on March 20).
Currently, with a total generation capacity of 25,083 MW (31.2 percent) combined cycle power plants account for the biggest share in the country’s total power generation capacity followed by gas power plants generating 29.9 percent, amid global trends where renewables are set to eclipse coal and regional moves such as Israel's coal reduction signal accelerating shifts.

US Summer Electricity Outlook 2022 projects rising renewable energy generation as utility-scale solar and wind capacity additions surge, while coal declines and natural gas shifts amid higher fuel prices and regional supply constraints.
Key Points
An EIA forecast of summer 2022 power: more solar and wind, less coal, and shifting gas use amid higher fuel prices.
✅ Solar +10 million MWh; wind +8 million MWh vs last summer
✅ Coal generation -20 million MWh amid supply constraints, retirements
✅ Gas prices near $9/MMBtu; slight national gen decline
In our Summer Electricity Outlook, a supplement to our May 2022 Short-Term Energy Outlook, we expect the largest increases in U.S. electric power sector generation this summer will come from renewable energy sources such as wind and solar generation. These increases are the result of new capacity additions. We forecast utility-scale solar generation between June and August 2022 will grow by 10 million megawatthours (MWh) compared with the same period last summer, and wind generation will grow by 8 million MWh. Forecast generation from coal and natural gas declines by 26 million MWh this summer, although natural gas generation could increase in some electricity markets where coal supplies are constrained.
For recent context, overall U.S. power generation in January rose 9.3% year over year, the EIA reports.
Wind and solar power electric-generating capacity has been growing steadily in recent years. By the start of June, we estimate the U.S. electric power sector will have 65 gigawatts (GW) of utility-scale solar-generating capacity, a 31% increase in solar capacity since June 2021. Almost one-third of this new solar capacity will be built in the Texas electricity market. The electric power sector will also have an estimated 138 GW of wind capacity online this June, which is a 12% increase from last June.
Along with growth in renewables capacity, we expect that an additional 6 GW of new natural gas combined-cycle generating capacity will come online by June 2022, an increase of 2% from last summer. Despite this increase in capacity, we expect natural gas-fired electricity generation at the national level will be slightly (1.3%) lower than last summer.
We forecast the price of natural gas delivered to electric generators will average nearly $9 per million British thermal units between June and August 2022, which would be more than double the average price last summer. The higher expected natural gas prices and growth in renewable generation will likely lead to less natural gas-fired generation in some regions of the country.
In contrast to renewables and natural gas, the electricity industry has been steadily retiring coal-fired power plants over the past decade. Between June 2021 and June 2022, the electric power sector will have retired 6 GW (2%) of U.S. coal-fired generating capacity.
In previous years, higher natural gas prices would have resulted in more coal-fired electricity generation across the fleet. However, coal-fired power plants have been limited in their ability to replenish their historically low inventories in recent months as a result of mine closures, rail capacity constraints, and labor market tightness. These coal supply constraints, along with continued retirement of generating capacity, contribute to our forecast that U.S. coal-fired generation will decline by 20 million MWh (7%) this summer. In some regions of the country, these coal supply constraints may lead to increased natural gas-fired electricity generation despite higher natural gas prices.
BC Hydro pandemic electricity trends reveal weekend-like energy consumption patterns: later morning demand, earlier evenings, more cooking, streaming on smart TVs, and work-from-home routines, with tips to conserve using laptops and small appliances.
Key Points
Weekend-like shifts in power demand from work-from-home routines: later mornings, earlier evenings, and more streaming.
✅ Later morning electricity demand; earlier evening peaks
✅ More cooking and baking; increased streaming after dinner
✅ Conservation tips: laptops, small appliances, smart TVs
The latest report on electricity usage in British Columbia reveals the COVID-19 pandemic has created an atmosphere where every day feels like a Saturday, a pattern also reflected in BC electricity demand during peak seasons.
BC Hydro says overall power usage hasn't changed much, but similar Ontario electricity demand shifts suggest regional differences, while Manitoba demand fell more noticeably, and a survey of 500 people shows daily routines have shifted dramatically since mid-March when pandemic-related closures began.
The hydro report says, with nearly 40 per cent of B.C. residents working from home, trends in residential electricity use confirm almost half are sleeping in and eating breakfast later, while about a quarter say they are showering less.
Those patterns more closely resemble what hydro says is typical weekend power consumption, and could influence time-of-use rates as electricity demand occurs later in the morning and earlier in the evening.
The report also finds many people are cooking and baking more than before the pandemic, preparing the evening meal earlier, streaming or viewing more television after dinner even as Ottawa's electricity consumption dipped earlier in the pandemic, and 80 per cent are going to bed later.
Although electricity use is normal for this time of year, hydro says homebound residents can conserve by using laptops instead of desktops, small appliances such as Instant Pots instead of ovens, and streaming movies or TV shows on a smart televisions instead of game consoles, even as Hydro One peak rates continue to shape consumption patterns elsewhere.
2022 US Renewable Power Milestone highlights EIA data: wind and solar outpaced coal and nuclear, hydropower contributed, with falling levelized costs, grid integration, battery storage, and transmission upgrades shaping affordable, reliable clean power growth.
Key Points
The year US renewables, led by wind and solar, generated more power than coal and nuclear, per EIA.
✅ Wind and solar rose; levelized costs fell 70%-90% over decade
✅ Renewables surpassed coal and nuclear in 2022 per EIA
✅ Grid needs storage and transmission to manage intermittency
Electricity generated from renewables surpassed coal in the United States for the first time in 2022, as wind and solar surpassed coal nationwide, the U.S. Energy Information Administration has announced.
Growth in wind and solar significantly drove the increase in renewable energy and contributed 14% of the electricity produced domestically in 2022, with solar producing about 4.7% of U.S. power overall. Hydropower contributed 6%, and biomass and geothermal sources generated less than 1%.
“I’m happy to see we’ve crossed that threshold, but that is only a step in what has to be a very rapid and much cheaper journey,” said Stephen Porder, a professor of ecology and assistant provost for sustainability at Brown University.
California produced 26% of the national utility-scale solar electricity followed by Texas with 16% and North Carolina with 8%.
“This booming growth is driven largely by economics,” said Gregory Wetstone, president and CEO of the American Council on Renewable Energy, as renewables became the second-most prevalent U.S. electricity source in 2020 nationwide. “Over the past decade, the levelized cost of wind energy declined by 70 percent, while the levelized cost of solar power has declined by an even more impressive 90 percent.”
“Renewable energy is now the most affordable source of new electricity in much of the country,” added Wetstone.
The Energy Information Administration projected that the wind share of the U.S. electricity generation mix will increase from 11% to 12% from 2022 to 2023 and that solar will grow from 4% to 5% during the period, and renewables hit a record 28% share in April according to recent data. The natural gas share is expected to remain at 39% from 2022 to 2023, and coal is projected to decline from 20% last year to 17% this year.
“Wind and solar are going to be the backbone of the growth in renewables, but whether or not they can provide 100% of the U.S. electricity without backup is something that engineers are debating,” said Brown University’s Porder.
This presents challenges for engineers and policy-makers, Porder said, because existing energy grids were built to deliver power from a consistent source. Renewables such as solar and wind generate power intermittently. So battery storage, long-distance transmission and other steps will be needed to help address these challenges, he said.
Nighttime Thermoelectric Generator converts radiative cooling into renewable energy, leveraging outer space cold; a Stanford-UCLA prototype complements solar, serving off-grid loads with low-power output during peak evening demand, using simple materials on a rooftop.
Key Points
A device converting nighttime radiative cooling into electricity, complementing solar for low-power evening needs.
✅ Uses thermocouples to convert temperature gradients to voltage.
✅ Exploits radiative cooling to outer space for night power.
✅ Complements solar; low-cost parts suit off-grid applications.
Two years ago, one freezing December night on a California rooftop, a tiny light shone weakly with a little help from the freezing night air. It wasn't a very bright glow. But it was enough to demonstrate the possibility of generating renewable power after the Sun goes down.
Working with Stanford University engineers Wei Li and Shanhui Fan, University of California Los Angeles materials scientist Aaswath Raman put together a device that produces a voltage by channelling the day's residual warmth into cooling air, effectively generating electricity from thin air with passive heat exchange.
"Our work highlights the many remaining opportunities for energy by taking advantage of the cold of outer space as a renewable energy resource," says Raman.
"We think this forms the basis of a complementary technology to solar. While the power output will always be substantially lower, it can operate at hours when solar cells cannot."
For all the merits of solar energy, it's just not a 24-7 source of power, although research into nighttime solar cells suggests new possibilities for after-dark generation. Sure, we can store it in a giant battery or use it to pump water up into a reservoir for later, but until we have more economical solutions, nighttime is going to be a quiet time for renewable solar power.
Most of us return home from work as the Sun is setting, and that's when energy demands spike to meet our needs for heating, cooking, entertaining, and lighting.
Unfortunately, we often turn to fossil fuels to make up the shortfall. For those living off the grid, it could require limiting options and going without a few luxuries.
Shanhui Fan understands the need for a night time renewable power source well. He's worked on a number of similar devices, including carbon nanotube generators that scavenge ambient energy, and a recent piece of technology that flipped photovoltaics on its head by squeezing electricity from the glow of heat radiating out of the planet's Sun-warmed surface.
While that clever item relied on the optical qualities of a warm object, this alternative device makes use of the good old thermoelectric effect, similar to thin-film waste-heat harvesting approaches now explored.
Using a material called a thermocouple, engineers can convert a change in temperature into a difference in voltage, effectively turning thermal energy into electricity with a measurable voltage. This demands something relatively toasty on one side and a place for that heat energy to escape to on the other.
The theory is the easy part – the real challenge is in arranging the right thermoelectric materials in such a way that they'll generate a voltage from our cooling surrounds that makes it worthwhile.
To keep costs down, the team used simple, off-the-shelf items that pretty much any of us could easily get our hands on.
They put together a cheap thermoelectric generator and linked it with a black aluminium disk to shed heat in the night air as it faced the sky. The generator was placed inside a polystyrene enclosure sealed with a window transparent to infrared light, and linked to a single tiny LED.
For six hours one evening, the box was left to cool on a roof-top in Stanford as the temperature fell just below freezing. As the heat flowed from the ground into the sky, the small generator produced just enough current to make the light flicker to life.
At its best, the device generated around 0.8 milliwatts of power, corresponding to 25 milliwatts of power per square metre.
That might just be enough to keep a hearing aid working. String several together and you might just be able to keep your cat amused with a simple laser pointer. So we're not talking massive amounts of power.
But as far as prototypes go, it's a fantastic starting point. The team suggests that with the right tweaks and the right conditions, 500 milliwatts per square metre isn't out of the question.
"Beyond lighting, we believe this could be a broadly enabling approach to power generation suitable for remote locations, and anywhere where power generation at night is needed," says Raman.
While we search for big, bright ideas to drive the revolution for renewables, it's important to make sure we don't let the smaller, simpler solutions like these slip away quietly into the night.
