Grow ops are contributing to global warming and taking a bite out of the nationÂ’s power grid.

"People growing marijuana indoors use 1 per cent of the U.S. electricity supply," the San Francisco Business Times reports, "and they create 17 million metric tons of carbon dioxide every year not counting the smoke exhaled" according to a report by Evan Mills, an energy analyst at Lawrence Berkeley National Laboratory.

In order to produce some 17,000 metric tons of marijuana this year, Mills estimates authorized growers will use $5-billion US worth of energy. That works out to the output of seven big electric power plants.

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.

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

Hydroelectricity Under Pumped Storage Capacity

Pumped Storage Hydroelectricity balances renewable energy, stabilizes the grid, and provides large-scale energy storage using reservoirs and reversible turbines, delivering flexible peak power, frequency control, and rapid response to variable wind and solar generation.

 

Key Points

A reversible hydro system that stores energy by pumping water uphill, then generates flexible peak power.

✅ Balances variable wind and solar with rapid ramping

✅ Stores off-peak electricity in upper reservoirs

✅ Enhances grid stability, frequency control, and reserves

 

The expense of hydroelectricity is moderately low, making it a serious wellspring of sustainable power. The hydro station burns-through no water, dissimilar to coal or gas plants. The commonplace expense of power from a hydro station bigger than 10 megawatts is 3 to 5 US pennies for every kilowatt hour, and Niagara Falls powerhouse upgrade projects show how modernization can further improve efficiency and reliability. With a dam and supply it is likewise an adaptable wellspring of power, since the sum delivered by the station can be shifted up or down quickly (as meager as a couple of moments) to adjust to changing energy requests.

When a hydroelectric complex is developed, the task creates no immediate waste, and it for the most part has an extensively lower yield level of ozone harming substances than photovoltaic force plants and positively petroleum product fueled energy plants, with calls to invest in hydropower highlighting these benefits. In open-circle frameworks, unadulterated pumped storage plants store water in an upper repository with no normal inflows, while pump back plants use a blend of pumped storage and regular hydroelectric plants with an upper supply that is renewed to a limited extent by common inflows from a stream or waterway.

Plants that don't utilize pumped capacity are alluded to as ordinary hydroelectric plants, and initiatives focused on repowering existing dams continue to expand clean generation; regular hydroelectric plants that have critical capacity limit might have the option to assume a comparable function in the electrical lattice as pumped capacity by conceding yield until required.

The main use for pumped capacity has customarily been to adjust baseload powerplants, however may likewise be utilized to decrease the fluctuating yield of discontinuous fuel sources, while emerging gravity energy storage concepts broaden long-duration options. Pumped capacity gives a heap now and again of high power yield and low power interest, empowering extra framework top limit.

In specific wards, power costs might be near zero or once in a while negative on events that there is more electrical age accessible than there is load accessible to retain it; despite the fact that at present this is infrequently because of wind or sunlight based force alone, expanded breeze and sun oriented age will improve the probability of such events.

All things considered, pumped capacity will turn out to be particularly significant as an equilibrium for exceptionally huge scope photovoltaic age. Increased long-distance bandwidth, including hydropower imports from Canada, joined with huge measures of energy stockpiling will be a critical piece of directing any enormous scope sending of irregular inexhaustible force sources. The high non-firm inexhaustible power entrance in certain districts supplies 40% of yearly yield, however 60% might be reached before extra capaciy is fundamental.

Pumped capacity plants can work with seawater, despite the fact that there are extra difficulties contrasted with utilizing new water. Initiated in 1966, the 240 MW Rance flowing force station in France can incompletely function as a pumped storage station. At the point when elevated tides happen at off-top hours, the turbines can be utilized to pump more seawater into the repository than the elevated tide would have normally gotten. It is the main enormous scope power plant of its sort.

Alongside energy mechanism, pumped capacity frameworks help control electrical organization recurrence and give save age. Warm plants are substantially less ready to react to abrupt changes in electrical interest, and can see higher thermal PLF during periods of reduced hydro generation, conceivably causing recurrence and voltage precariousness.

Pumped storage plants, as other hydroelectric plants, including new BC generating stations, can react to stack changes in practically no time. Pumped capacity hydroelectricity permits energy from discontinuous sources, (for example, sunlight based, wind) and different renewables, or abundance power from consistent base-load sources, (for example, coal or atomic) to be put something aside for times of more popularity.

The repositories utilized with siphoned capacity are tiny when contrasted with ordinary hydroelectric dams of comparable force limit, and creating periods are regularly not exactly a large portion of a day. This technique produces power to gracefully high top requests by moving water between repositories at various heights.

Now and again of low electrical interest, the abundance age limit is utilized to pump water into the higher store. At the point when the interest gets more noteworthy, water is delivered once more into the lower repository through a turbine. Pumped capacity plans at present give the most monetarily significant methods for enormous scope matrix energy stockpiling and improve the every day limit factor of the age framework. Pumped capacity isn't a fuel source, and shows up as a negative number in postings.

The city of Medicine Hat, Alberta, is taking bold steps toward enhancing its energy infrastructure and reducing electricity consumption with the help of innovative technology. Recently, several grant winners have been selected to improve the city's electricity grid distribution and leverage artificial intelligence (AI) to adapt to electricity demands while optimizing energy use. These projects promise to not only streamline energy delivery but also contribute to more sustainable practices by reducing energy waste.

Advancing the Electricity Grid

Medicine Hat’s electricity grid is undergoing a significant transformation, thanks to a new set of initiatives funded by government grants that advance a smarter electricity infrastructure vision for the region. The city has long been known for its commitment to sustainable energy practices, and these new projects are part of that legacy. The winners of the grants aim to modernize the city’s electricity grid to make it more resilient, efficient, and adaptable to the changing demands of the future, aligning with macrogrid strategies adopted nationally.

At the core of these upgrades is the integration of smart grid technologies. A smart grid is a more advanced version of the traditional power grid, incorporating digital communications and real-time data to optimize the delivery and use of electricity. By connecting sensors, meters, and control systems across the grid, along with the integration of AI data centers where appropriate, the grid can detect and respond to changes in demand, adjust to faults or outages, and even integrate renewable energy sources more efficiently.

One of the key aspects of the grant-funded projects involves automating the grid. Automation allows for the dynamic adjustment of power distribution in response to changes in demand or supply, reducing the risk of blackouts or inefficiencies. For instance, if an area of the city experiences a surge in energy use, the grid can automatically reroute power from less-used areas or adjust the distribution to avoid overloading circuits. This kind of dynamic response is crucial for maintaining a stable and reliable electricity supply.

Moreover, the enhanced grid will be able to better incorporate renewable energy sources such as solar and wind power, reflecting British Columbia's clean-energy shift as well, which are increasingly important in Alberta’s energy mix. By utilizing a more flexible and responsive grid, Medicine Hat can make the most of renewable energy when it is available, reducing reliance on non-renewable sources.

Using AI to Reduce Energy Consumption

While improving the grid infrastructure is an essential first step, the real innovation comes in the form of using artificial intelligence (AI) to reduce energy consumption. Several of the grant winners are focused on developing AI-driven solutions that can predict energy demand patterns, optimize energy use in real-time, and encourage consumers to reduce unnecessary energy consumption.

AI can be used to analyze vast amounts of data from across the electricity grid, such as weather forecasts, historical energy usage, and real-time consumption data. This analysis can then be used to make predictions about future energy needs. For example, AI can predict when the demand for electricity will peak, allowing the grid operators to adjust supply ahead of time, ensuring a more efficient distribution of power. By predicting high-demand periods, AI can also assist in optimizing the use of renewable energy sources, ensuring that solar and wind power are utilized when they are most abundant.

In addition to grid management, AI can help consumers save energy by making smarter decisions about how and when to use electricity. For instance, AI-powered smart home devices can learn household routines and adjust heating, cooling, and appliance usage to reduce energy consumption without compromising comfort. By using data to optimize energy use, these technologies not only reduce costs for consumers but also decrease overall demand on the grid, leading to a more sustainable energy system.

The AI initiatives are also expected to assist businesses in reducing their carbon footprints. By using AI to monitor and optimize energy use, industrial and commercial enterprises can cut down on waste and reduce energy-related operational costs, while anticipating digital load growth signaled by an Alberta data centre agreement in the province. This has the potential to make Medicine Hat a more energy-efficient city, benefiting both residents and businesses alike.

A Sustainable Future

The integration of smart grid technology and AI-driven solutions is positioning Medicine Hat as a leader in sustainable energy practices. The city’s approach is focused not only on improving energy efficiency and reducing waste but also on making electricity consumption more manageable and adaptable in a rapidly changing world. These innovations are a crucial part of Medicine Hat's long-term strategy to reduce carbon emissions and meet climate goals while ensuring reliable and affordable energy for its residents.

In addition to the immediate benefits of these projects, the broader impact is likely to influence other municipalities across Canada, including insights from Toronto's electricity planning for rapid growth, and beyond. As the technology matures and proves successful, it could set a benchmark for other cities looking to modernize their energy grids and adopt sustainable, AI-driven solutions.

By investing in these forward-thinking technologies, Medicine Hat is not only future-proofing its energy infrastructure but also taking decisive steps toward a greener, more energy-efficient future. The collaboration between local government, technology providers, and the community marks a significant milestone in the city’s commitment to innovation and sustainability.

Sudbury, Ont., eco groups say sustainability is key to grid's future

Sudbury Electrification and Grid Expansion is driving record power demand, EV charging, renewable energy planning, IESO forecasts, smart grid upgrades, battery storage, and industrial electrification, requiring cleaner power plants and transmission capacity in northern Ontario.

 

Key Points

Rising electricity demand and clean energy upgrades in Sudbury to power EVs, industry, and a smarter, expanded grid.

✅ IESO projects system size may need to more than double

✅ EVs and smart devices increase peak and off-peak load

✅ Battery storage and V2G can support reliability and resiliency

 

Sudbury, Ont., is consuming more power than ever, amid an electricity supply crunch in Ontario, according to green energy organizations that say meeting the demand will require cleaner energy sources.

"This is the welfare of the entire city on the line and they are putting their trust in electrification," said David St. Georges, manager of communications at reThink Green, a non-profit organization focused on sustainability in Sudbury.

According to St. Georges, Sudbury and northern Ontario can meet the growing demand for electricity to charge clean power for EVs and smart devices. 

According to the Independent Electricity System Operator (IESO), making a full switch from fossil fuels to other renewable energy sources could require more power plants, while other provinces face electricity shortages of their own.

"We have forecasted that Ontario's electricity system will need significant expansion to meet this, potentially more than doubling in size," the IESO told CBC News in an emailed statement.

Electrification in the industrial sector is adding greater demand to the electrical grid as electric cars challenge power grids in many regions. Algoma Steel in Sault Ste. Marie and ArcelorMittal Dofasco in Hamilton both aim to get electric arc furnaces in operation. Together, those projects will require 630 megawatts.

"That's like adding four cities the size of Sudbury to the grid," IESO said.

Devin Arthur, chapter president of the Electric Vehicle society in Greater Sudbury, said the city is coming full circle with fully electrifying its power grid, reflecting how EVs are a hot topic in Alberta and beyond.

"We're going to need more power," he said.

"Once natural gas was introduced, that kind of switched back, and everyone was getting out of electrification and going into natural gas and other sources of power."

Despite Sudbury's increased appetite for electricity, Arthur added it's also easier to store now as Ontario moves to rely on battery storage solutions.

"What that means is you can actually use your electric vehicle as a battery storage device for the grid, so you can actually sell power from your vehicle that you've stored back to the grid, if they need that power," he said.

Harneet Panesar, chief operating officer for the Ontario Energy Board, told CBC the biggest challenge to going green is seeing if it can work around older infrastructure, while policy debates such as Canada's 2035 EV sales mandate shape the pace of change.

"You want to make sure that you're building in the right spot," he said.

"Consumers are shifting from combustion engines to EV drivetrains. You're also creating more dependency. At a very high level, I'm going to say it's probably going to go up in terms of the demand for electricity."

Fossil fuels are the first to go for generating electricity, said St. Georges.

"But we're not there yet, because it's not a light switch solution. It takes time to get to that, which is another issue of electrification," he said.

"It's almost impossible for us not to go that direction."

Closure of 3 Southern California power plants likely to be postponed

California Gas Plant Extensions keep Ormond Beach, AES Alamitos, and Huntington Beach on standby for grid reliability during heat waves, as regulators balance renewables, battery storage, and power, pending State Water Resources Control Board approval.

 

Key Points

State plan extending three coastal gas plants to 2026, adding capacity as California expands renewables and storage.

✅ Extends Ormond Beach, AES Alamitos, AES Huntington Beach

✅ Mitigates blackout risk during extreme heat and peak demand

✅ Pending State Water Resources Control Board approval

 

Temperatures in many California cities are cooling down this week, but a debate is simmering on how to generate enough electricity to power the state through extreme weather events while transitioning away from a reliance on fossil fuels as clean energy progress indicates statewide.

The California Energy Commission voted Wednesday to extend the life of three gas power plants along the state’s southern coast through 2026, even as natural-gas electricity records persist nationwide, postponing a shutoff deadline previously set for the end of this year. The vote would keep the decades-old facilities _ Ormond Beach Generating Station, AES Alamitos and AES Huntington Beach — open so they can run during emergencies.

The state is at a greater risk of blackouts during major events when many Californians simultaneously crank up their air conditioning, such as a blistering heat wave, illustrated by widespread utility shutoffs in recent years.

“We need to move faster in incorporating renewable energy. We need to move faster at incorporating battery storage. We need to build out chargers faster,” commissioner Patricia Monahan said amid an ongoing debate over the classification of nuclear power in California. “We’re working with all the energy institutions to do that, but we are not there yet.”

The plan, put together by the state’s Department of Water Resources, still needs final approval from the State Water Resources Control Board, which may vote on the issue next week. Democratic Gov. Gavin Newsom signed legislation last year creating an energy reserve the state could use as a last resort if there is likely to be an energy shortage, a challenge mirrored by Ontario electricity shortfall concerns elsewhere. The law allowed the Department of Water Resources to fund or secure power sources in those instances, after PG&E shutdown reasons drew attention to grid vulnerabilities.

The commission acknowledged it was a difficult decision. Environmentalists say the state needs to transition to more short- and long-term solutions that will help it move away from fossil fuels and to rely more on renewable energy sources like solar and wind, similar to Ontario's clean power push in recent years. They’re also concerned about the health impacts associated with pollution from gas plants.

Ukraine Leans on Imports to Keep the Lights On

Ukraine Electricity Imports surge to record levels as EU neighbors bolster grid stability amid Russian strikes, supporting energy security, preventing blackouts, and straining cross-border transmission capacity while Ukraine rebuilds damaged infrastructure and diversifies with renewables.

 

Key Points

Emergency EU power purchases stabilizing Ukraine’s grid after war damage.

✅ Record 19,000 MWh per day from EU interconnectors

✅ Supports grid stability and blackout prevention

✅ Cost and transmission upgrades challenge sustainability

 

Russia's ongoing war in Ukraine has extended far beyond the battlefield, with critical infrastructure becoming a target. Ukraine's once-robust energy system has sustained significant damage amid energy ceasefire violations and Russian missile and drone strikes. To cope with these disruptions and maintain power supplies for Ukrainian citizens, the country is turning to record-breaking electricity imports from neighboring European nations.

Prior to the war, Ukraine enjoyed a self-sufficient energy sector, even exporting electricity to neighboring countries. However, targeted attacks on power plants and transmission lines have crippled generation capacity. The situation is particularly dire in eastern and southern Ukraine, where ongoing fighting has caused extensive damage.

Faced with this energy crisis, Ukraine is looking to Europe for a lifeline. The country's energy ministry has announced plans to import a staggering amount of electricity – exceeding 19,000 megawatt-hours (MWh) per day – to prepare for winter and stabilize supplies. This surpasses the previous record set in March 2024 and represents a significant increase in Ukraine's reliance on external power sources.

Several European nations are stepping up to support Ukraine. Countries like Poland, Slovakia, Romania, Hungary, which maintains quiet energy ties with Russia today, and Moldova have agreed to provide emergency electricity supplies. These imports will help stabilize Ukraine's power grid and prevent widespread blackouts, especially during peak consumption hours.

The reliance on imports, however, presents its own set of challenges. Firstly, the sheer volume of electricity needed puts a strain on the capacity of neighboring grids. Upgrading and expanding transmission infrastructure will be crucial to ensure a smooth flow of electricity. Secondly, the cost of imported electricity can be higher than domestically generated power amid price hikes and instability globally, placing additional pressure on Ukraine's already strained finances.

Beyond these immediate concerns, the long-term implications of relying on external energy sources need to be considered. Ukraine's long-term goal is to rebuild its own energy infrastructure and regain energy independence. International assistance, including energy security support measures, will be crucial in this endeavor. Financial aid and technical expertise can help Ukraine repair damaged power plants, diversify its energy mix through further investment in renewables, and develop more resilient grid infrastructure.

The war in Ukraine has underscored the importance of energy security. A nation's dependence on a single source of energy, be it domestic or foreign, leaves it vulnerable to disruption, as others consider national security and fossil fuels in their own policies. For Ukraine, diversification and building a more resilient energy infrastructure are key takeaways from this crisis.

The international community also has a role to play. Supporting Ukraine's energy sector not only helps the nation weather the current crisis but also strengthens European energy security as a whole, where concerns over Europe's energy nightmare remain pronounced. A stable and independent Ukraine, less reliant on Russian energy, contributes to a more secure and prosperous Europe.

As the war in Ukraine continues, the battle for energy security rages on. While the immediate focus is on keeping the lights on through imports, the long-term goal for Ukraine is to rebuild a stronger, more resilient energy sector that can power the nation's future. The international community's support will be crucial in helping Ukraine achieve this goal.
