Puna Geothermal Venture marked 15 years in business recently.

The company taps the might of Kilauea volcano to generate electricity, providing nearly one-fifth of the Big Island's power.

PGV is looking to increase production by eight megawatts of power. That would up the company's total capacity to 41 megawatts.

Lieutenant Governor James "Duke" Aiona says geothermal production fits with Hawaii's clean energy initiative. It calls for the state to knock down its fossil fuel consumption to 30 percent.

PGV's plant sells 30 megawatts of renewable energy to Hawaii Electric Light Company on a continuous basis. That provides nearly 20 percent of the Big Island's electricity needs.

Solar-powered pot: Edmonton-area producer unveils largest rooftop solar array

Freedom Cannabis solar array powers an Acheson cannabis facility with 4,574 rooftop panels, a 1,830-kilowatt system by Enmax, cutting greenhouse gas emissions, lowering energy costs, and advancing renewable energy, sustainability, and operational efficiency in Edmonton.

 

Key Points

A 1,830-kW rooftop solar system with 4,574 panels, cutting GHG emissions and energy costs at the Acheson facility.

✅ 1,830-kW array offsets 1,000+ tonnes GHG annually

✅ Supplies ~8% of annual power; saves $200k-$300k per year

✅ 4,574 rooftop panels installed by Enmax in Acheson

 

Electricity consumption is one of the biggest barriers to going green in the cannabis industry, where the energy demands of cannabis cultivation often complicate sustainability, but an Edmonton-area pot producer has come up with a sunny solution.

Freedom Cannabis unveiled the largest rooftop solar system used by a cannabis facility in Canada at its 126,000-square foot Acheson location, 20 kilometres west of Edmonton, as solar power in Alberta continues to surge, on Tuesday.

The "state-of-the-art" 1,830-kilowatt solar array—made up of 4,574 panels—was supplied by Enmax and will offset more than 1,000 tonnes of greenhouse gas emissions each year, reflecting how new Alberta solar facilities are undercutting natural gas on price, the company said.

That will supply roughly eight per cent of the building's annual power consumption and reduce costs by $200,000 to $300,000 annually.

"This strategy will supplement our operating costs for power by up to eight to 10 per cent, so it is something that in time will save us costs on power requirements," said Troy Dezwart, co-founder of Freedom Cannabis.

Dezwart said sustainability was an important issue to the company from its outset, aligning with an Alberta renewable energy surge that is expected to power thousands of jobs.

"We're fortunate enough to be able to have these types of options and pursue them," said Dezwart.

The entire system cost Freedom Cannabis $2.6 million to build, but nearly a million of that came from a provincial rebate program that has since been cancelled by the UCP government, even as a federal green electricity deal with an Edmonton company signals ongoing support.

The company cited a 2017 report that found cannabis growers in the U.S. used enough electricity to power 1.7-million homes, and said cannabis-related power consumption is expected to increase by 1,250 per cent in Ontario over the next five years, even though Canadian solar demand has been lagging overall.

“It’s more important than ever for businesses to manage their energy footprint, and solar is an important part of that solution,” Enmax director Jason Atkinson, said. “This solar installation will help reduce operating costs and offset a significant portion of GHG emissions for decades to come.”

Freedom says it has other initiatives underway to reduce its footprint, in a region planning the Edmonton airport solar farm among other projects, including water remediation and offering 100 per cent recyclable cannabis packaging tins.

The company's first crops are expected to go to market in December.

Report: Duke Energy to release climate report under investor pressure

Duke Energy zero-coal 2050 plan outlines a decarbonized energy mix, aligning with Paris goals, cutting greenhouse gas emissions, driven by investor pressure, shifting to natural gas, extending nuclear power, and phasing out coal.

 

Key Points

An investor-driven scenario to end coal by 2050, shift to natural gas, extend nuclear plants, and manage climate risk.

✅ Eliminates coal from the generation mix by 2050

✅ Prioritizes natural gas transitions without CCS breakthroughs

✅ Extends nuclear plant licenses to limit carbon emissions

 

One of America’s largest utility companies, Duke Energy, is set to release a report later this month that sketches a drastically changed electricity mix in a carbon-constrained future.

The big picture: Duke is the latest energy company to commit to releasing a report about climate change in response to investor pressure, echoing shifts such as Europe's oil majors going electric across the sector, conveyed by non-binding but symbolically important shareholder resolutions. Duke provides electricity to more than seven million customers in the Carolinas, the Midwest and Florida.

Gritty details: The report is expected to find that coal, currently 33% of Duke’s mix, gone entirely from its portfolio by 2050 in a future scenario where the world has taken steps to cut greenhouse gas emissions, and where global coal-fired electricity use is falling markedly, to a level consistent with keeping global temperatures from rising two degrees Celsius. That’s the big ambition of the 2015 Paris climate deal, but the current commitments aren’t close to reaching that.

What they're saying: “What’s difficult about this is we are trying to overlay what we understand currently about technology,” Lynn Good, Duke CEO, told Axios in an interview on the sidelines of a major energy conference here.

She went on to say that this scenario of zero coal by 2050 doesn’t assume any breakthroughs in technology that captures carbon emissions from coal-fired power plants. “We don’t see that technology today, and we need to make economic decisions to get those units moving and replacing them with natural gas.”

Good also stressed the benefits of its several nuclear power plants, highlighting the role of sustaining U.S. nuclear power in decarbonization, which emit no carbon emissions. She said Duke isn’t considering investing in new nuclear plants, but plans to seek federal relicensing of current plants.

“If I turn them off, the resource that would replace them today is natural gas, so carbon will go up,” Good said. “Our objective is to continue to keep those plants as long as possible.”

What’s next: A spokesman said the other details of their 2050 scenario estimates will be available when the report is officially released by month’s end.

Axios reports that Duke Energy will release a report later this month that detail the utility's efforts to mitigate climate change risks and plan carbon-free electricity investments across its operations. The report includes a scenario that eliminates coal entirely from the company's power mix by 2050. Coal currently makes up about a third of Duke's generation.

Duke CEO Lynn Good told the news outlet the scenario ending coal-fired generation assumes no technological advances in emissions capture, seemingly leaving open the possibility.

Last year, a report by the Union of Concerned Scientists concluded one in four of the remaining operating coal-fired plants in the U.S. are slated for closure or conversion to natural gas, amid falling power-sector carbon emissions across the country. Duke's report is expected to be released by the end of the month.

Duke's report on its carbon plans comes at the behest of shareholders, a trend utility companies have seen growing among investors who are increasingly concerned about companies' sustainability and their financial exposure to climate policy.

Last year, a majority of shareholders of Pennsylvania utility PPL Corp. called on company management to publish a report on how climate change policies and technological innovations will affect the company's bottom line. Almost 60% of shareholders voted in favor of the non-binding proposal.

The vote, reportedly a first for the power sector, followed a similar decision by shareholders of Occidental Petroleum, which was supported by about 66% of shareholders.

Duke's Good told Axios that right now the utility does not see the coal technology on the horizon that would keep it operating plants. “We don't see that technology today, and we need to make economic decisions to get those units moving and replacing them with natural gas," Good said. However, it does not mean the utility is making near-term efforts to erase coal from its power mix. However, some utilities are taking those steps as they prepare for en energy landscape with more carbon regulations.

In addition to the 25% of coal plants heading for closure or conversion, the UCS report also said that another 17% of the nation’s operating coal plants are uneconomic compared with natural gas-fired generation, and could face retirement soon. But there is plenty of ongoing research into "clean coal" possibilities, and the federal government has expressed an interest in smaller, modular coal units.

Canada expected to miss its 2035 clean electricity goals

Canada 2035 Clean Electricity Target faces a 48.4GW shortfall as renewable capacity lags; accelerating wind, solar PV, grid upgrades, and coherent federal-provincial policy is vital to reach zero-emissions power and strengthen transmission and distribution.

 

Key Points

Canada's plan to supply nearly 100% of electricity from zero-emitting sources by 2035, requiring renewable buildout.

✅ Average adds 2.6GW; shortfall totals 48.4GW by 2035

✅ Expand wind, solar PV, storage, and grid modernization

✅ Align federal-province policy; retire or convert thermal plants

 

GlobalData’s latest report, ‘Canada Power Market Size and Trends by Installed Capacity, Generation, Transmission, Distribution and Technology, Regulations, Key Players and Forecast, 2022-2035’, discusses the power market structure of Canada and, amid looming power challenges, provides historical and forecast numbers for capacity, generation and consumption up to 2035. Detailed analysis of the country’s power market regulatory structure, competitive landscape and a list of major power plants are provided. The report also gives a snapshot of the power sector in the country on broad parameters of macroeconomics, supply security, generation infrastructure, transmission and distribution infrastructure, electricity import and export scenario, degree of competition, regulatory scenario, and future potential. An analysis of the deals in the country’s power sector is also included in the report.

Canada is expected to fall short of its 2035 clean electricity target after reviewing the country’s current renewable capacity activity. The country has targeted to produce nearly 100% of its electricity from zero-emitting sources by 2035, while electricity associations' net-zero goals extend to 2050; however, the country is adding only 2.6GW of annual renewable capacity additions on average every year, which would mean a cumulative shortfall of 48.4GW.

Canada has good governmental support, but it is not doing enough to ensure its targets are met. If the country is to meet its target to produce nearly 100% of electricity from zero-emitting sources by 2035, the country should both increase the capacity and efficiency of renewable power plants, as well as provide comprehensive end-to-end policies at both the federal and provincial levels, as debates over whether Ontario is embracing clean power continue across provinces. It should also involve communities and businesses in raising awareness of the benefits of adopting renewable energy.

The country has a large amount of proven natural gas and oil reserves that are proving too tempting an opportunity, and the Canadian Government is planning to increase the capacity of its gas-based plants under net-zero regulations permit some gas in the power mix, to secure real-time demand and supply. However, the country’s dependency on gas-based plants creates a major challenge to achieve its 2035 clean electricity target.

If the Canadian Government is to meet its 2035 targets, it should draw on examples from its European counterparts and add renewable capacity at a rapid pace, while balancing demand and emissions in key provinces. One advantage for Canada here is that it does not have land constraints, which is common in other major renewable power-generating countries. This could give the country an estimated 6.1GW of renewable capacity every year on average during the 2021-2035 period: enough capacity to meet its target. Most of these installations are expected to be for wind and solar PV.

Changing provincial governments are not helpful when it comes to implementing long-term projects, especially as Ontario faces looming electricity shortfalls that heighten planning risks, and continued stopping and starting of projects like this will only be damaging to renewable goals. Another way the country can achieve its target is by converting thermal power plants into clean energy plants and providing a roadmap or timeline for provinces to retire thermal power plants completely, even as scrapping coal can be costly for some systems.

Canada’s GDP (at constant prices) increased from $1,617.3bn in 2010 to $1,924.5bn in 2021, at a CAGR of 1.6%. The GDP (at constant prices) of the country declined sharply from $1,943.8bn in 2019 to $1,840.5bn in 2020 because of Covid-19 pandemic. After the recommencement of regular industrial and trade activities, the GDP grew by 4.6% in 2021 from 2020. The GDP is expected to cross pre-pandemic levels by the end of 2022.

Christmas electricity spike equivalent to roasting 1.5 million turkeys: BC Hydro

BC Hydro Holiday Energy Saving Tips highlight electricity usage trends and power conservation during Christmas cooking. Use efficient appliances, lower the thermostat, and track consumption with MyHydro to reduce bills while hosting guests.

 

Key Points

Guidelines from BC Hydro to cut holiday electricity usage via efficient cooking, smart thermostats, and MyHydro tracking.

✅ Use microwave, toaster oven, or slow cooker to save power.

✅ Batch-bake cookies and pies to minimize oven cycles.

✅ Set thermostat to 18 C and monitor use with MyHydro.

 

BC Hydro is reminding British Columbians to conserve power over the holidays after a report commissioned by the utility found the arrival of guests for Christmas dinner results in a 15% increase in electricity usage, and it expects holiday usage to rise as gatherings ramp up.

Cooking appears to be the number one culprit for the uptick in peoples’ hydro bills. According to BC Hydro press release, British Columbians use about 8,000 megawatt hours more of electricity by mid-day Christmas — that's about 1.5 million turkeys roasted in electric ovens — while Ontario electricity demand shifted as people stayed home during the pandemic.
 article continues below 

About 95% of British Columbians said they would make meals at home from scratch over the holiday season, mirroring the uptick in residential electricity use observed during the pandemic. The survey found that inviting friends or family over trumped any plans people had to buy pre-made meals or order take-out. Six in 10 respondents said they would also rather bake holiday treats than pick them up pre-made from the store. 

The survey also showed people in B.C. are taking steps to reduce their electricity usage, echoing earlier findings that many British Columbians changed daily electricity habits during the pandemic. When participants were asked whether they were conscious of how much electricity they used when visiting friends or family, 80% said they would be taking steps to limit their usage.


And while cooking meals from scratch over the holidays may contribute to a spike in a person's electricity bill, some studies have found that, when comparing their overall environmental impact against that of ready-made meals, a roasted dinner has a lower negative impact.

Still, there are many ways to improve your energy efficiency and save some money over the holiday season, and conserving can also help the grid during events like the recent atypical storm response noted by BC Hydro. BC Hydro recommends:

• using smaller appliances whenever possible, such as a microwave, crockpot or toaster oven as they use less than half the power of a regular electric oven;

• baking cookies or pies in batches to save energy;

• turning down the household thermostat to 18 C when possible to reduce costs during peak hydro rates where applicable;

• and tracking how much electricity you use through the MyHydro tool alongside potential time-of-use rates for smarter scheduling

Senate Democrats push for passage of energy-related tax incentives

Senate Renewable Energy Tax Credits face Finance Committee scrutiny, with Democrats urging action on tax extenders, clean energy incentives, and climate policy, while Republicans cite prior wins in wind, biodiesel, and EV credits.

 

Key Points

Legislative incentives debated in the Senate Finance Committee to extend and align clean energy tax benefits.

✅ Democrats press hearings and action on energy tax policy

✅ Focus on clean energy, EVs, wind, biodiesel, and resilience

✅ Grassley cites prior extenders; disputes push for bigger subsidies

 

A group of 27 Democratic senators is calling for action in the Senate Finance Committee on extending energy-related tax credits and examining new tax proposals, especially those that incentivize renewable energy projects and align with FERC action on aggregated DERs across the grid.

Sen. Ron Wyden, D-Ore., the ranking Democrat on the Senate Finance Committee, who recently introduced a wildfire-resilient grid bill with Sen. Merkley, led the group of Democrats in writing a letter Tuesday to Sen. Charles Grassley, R-Iowa, who chairs the committee.

“Despite numerous opportunities, including in the recent tax extenders package, the Finance Committee has failed to take action on the dozens of energy tax proposals pending before it,” they wrote. “It is critical that the Committee move to address these issues in a timely manner, along with much needed policy changes that heed warnings on regulatory rollbacks to combat the damage and growing dangers caused by global climate change.”

The number of Americans ages 65 and over is projected to nearly double by 2060. And most would prefer to age in place and hiresenior caregivers if needed.

They pointed out that the Senate Finance Committee hasn’t held a single hearing on energy tax policy during the previous congressional term, and has yet to hold one in the current one.

“The sole energy tax-related recommendation of the Committee’s temporary policy task forces was ignored in the tax extender legislation passed in December 2019, along with nearly all proposals put forward in members’ legislation this Congress,” they wrote. “This Committee must fulfill its role in examining members’ energy tax proposals and in bolstering our nation’s efforts to combat climate change, including a clean electricity standard approach that sets firm targets.”

They noted that In 2019, the global average temperature was the second highest ever recorded and the past decade was the hottest ever. The lawmakers pointed to raging wildfires and increased flooding in the western part of the U.S., as well as challenges in California’s power system during the transition, causing unprecedented destruction over the past several years. They called for tax incentives for renewable energy to help combat climate change.

“Gaps in the tax code have disadvantaged complementary technologies that could improve climate resiliency and provide additional emissions reductions,” they wrote. “While power sector emissions continue to decrease, emissions from transportation, heavy industry and agriculture have stayed level or increased over the past 10 years, even amid $5 gas not spurring a green shift in consumer behavior. The United States is not on pace to meet its international climate commitments, to say nothing of the reductions necessary to stave off the worst potential outcomes of global warming.”

Grassley reacted to the letter, noting that he had worked to get tax extenders legislation passed, even as some states consider bans on clean energy use by utilities. "I begged Democrats for a year to help me get an extenders package passed, about half of which were green energy policies, so this rings hollow," he said in a statement Tuesday. "We wouldn’t have a wind energy credit or a biodiesel credit but for me, let alone an extension of either. Democrats were holding up these green energy provisions in an attempt to get a big expansion of taxpayer subsidies for rich Tesla owners."

Quebec shatters record for electricity consumption once again

Hydro Quebec Power Consumption Record surges amid extreme cold, peak demand, and grid stress, as Hydro-Quebec urges energy conservation, load management, and reduced heating during morning and evening peaks across Montreal and southern Quebec.

 

Key Points

Quebec's grid hit 40,300 MW during an extreme cold snap, setting a new record and prompting conservation appeals.

✅ Lower thermostats 1-2 C in unused rooms during peak hours

✅ Delay dishwashers, dryers, and hot water use to off-peak

✅ Peak windows: 6-9 a.m. and 4-8 p.m.; import power if needed

 

Hydro Quebec says it has once again set a new record for power consumption, echoing record-breaking demand in B.C. in 2021 as extreme cold grips much of the province.

An extreme cold warning has been in effect across southern Quebec since Friday morning, straining the system, just as Calgary's electricity use soared during a frigid February, as Quebecers juggle staying warm and working from home.

Hydro Québec recorded consumption levels reaching 40,300 megawatts as of 8 a.m. Friday, breaking a previous record of 39,000 MW (with B.C. electricity demand hit an all-time high during a similar cold snap) that was broken during another cold snap on Jan 11. 

The publicly owned utility is now asking Quebecers to reduce their electricity consumption as much as possible today and tomorrow, a move consistent with clean electricity goals under federal climate pledges, predicting earlier in the morning the province would again reach an all-time high.

Reducing heating by just one or two degrees, especially in rooms that aren't being used, is one step that people can take to limit their consumption. They can also avoid using large appliances like the dishwasher and clothing dryer as often, and shortening the use of hot water. 

"They're small actions, but across millions of clients, it makes a difference," said Cendrix Bouchard, a spokesperson with Hydro Québec, while speaking with Tout un matin.

"We understand that asking this may pose challenges for some who are home throughout the day because they are working remotely, but if people are able to contribute, we appreciate it."

The best time to try and limit electricity usage is in the morning and evening, when electricity usage tends to peak, Bouchard said.

The province can import electricity from other regions if Quebec's system reaches its limits, even as the utility pursues selling to the United States as part of its long-term strategy, he added.

Temperatures dropped to –24 C in Montreal at 7 a.m., with a wind chill of –29 C. 

It will get colder across the south of the province through the evening and wind chills are expected to make it feel as cold as – 40 until Saturday morning, Environment Canada warned.

Those spending time outdoors are at a higher risk of frostbite and hypothermia.

"Frostbite can develop within minutes on exposed skin, especially with wind chill," Environment Canada said.

Conserving energy
Hydro-Québec has signed up 160,000 clients to a flexible billing plan similar to BC Hydro's winter payment plan that allows them to pay less for energy — as long as they use it during non-peak periods.

Quebec's energy regulator, the Régie de l'énergie, also forces crypto-currency mining operations to shut down for some hours  on peak-demand days, a topic where BC Hydro's approach to crypto mining has also drawn attention, Bouchard said.

Hydro-Québec says the highest consumption periods are usually between 6 a.m.-9 a.m. and 4 p.m.-8 p.m.
