If youÂ’re a recent convert to smartphones, youÂ’re probably still discovering all the amazing things that your new BlackBerry, Android phone or iPhone can do. But one thing you most likely found out right away: the more you do, the shorter your phoneÂ’s battery lasts.

While a standard cellphone’s charge can easily go three days or more, many smartphone owners are dismayed to learn that their new mobile toy requires charging every 24 hours, or even more often. It was great that I could use one device — my iPhone — to check my calendar and respond to multiple incoming calls during the recent Consumer Electronics Show, but I paid the price when its battery died at 2 p.m.

The answer was not to desperately search for an electrical outlet to recharge the phone (though IÂ’ve done that) or to consider giving up the phone (done that, too), but rather to figure out a strategy to reduce energy consumption while still having it available for essential tasks. Whether youÂ’re using a laptop or a smartphone, the devices can be tweaked to get the most out of its lithium-ion batteries.

All things being equal, the CDMA mobile standard used by Verizon uses more power than a GSM network, principally used by AT&T and T-Mobile. If battery life is critical, you might want to consider GSM as long as its coverage meets your needs.

The brighter your screen, the more juice youÂ’re using. If youÂ’re in a dimly lit room, turn down your LCD screenÂ’s brightness. If your device has an auto-dimming feature that detects the light in a room, use it. Similarly, if you use your smartphone or laptop to play music, lower the volume.

If you have a BlackBerry, the companyÂ’s holster will automatically turn off the screen when you insert the phone.

It is great that you can use Bluetooth technology to connect your smartphone to a headset, or use Wi-Fi to speed up the downloading of e-mail messages. But when youÂ’re not using that headset or not near a Wi-Fi hot spot, turn off those features on the phone or laptop.

The reason is that portable devices will continue to look for Wi-Fi or a Bluetooth headset, using power.

Similarly, put your phone to sleep when it is in standby. On an iPhone, you do so through the “Settings” icon. On a BlackBerry, use the “Manage Connections” icon.

Your smartphone is also continually looking for a cellphone signal. If youÂ’re in a weak signal area, your phone must work even harder to find one, decreasing battery life. If you know that there is no coverage in your area, turn off your portable deviceÂ’s mobile capabilities.

If your GSM 3G network is not available or the signal is weak, the battery will drain faster looking for one. Consider turning off the phoneÂ’s 3G network or using the slower EDGE network instead. It will make Web access slower but wonÂ’t affect phone call quality.

Mobile smartphones can check for e-mail messages and instant messages automatically. Or they can be set to “push” notifications as soon as they arrive in your server’s mailbox.

Both strategies can be power hogs. To increase your battery life, turn off push and increase the interval between when the phone checks for new messages. Or better, set up your phone to check for messages manually.

The simplest way to cut power to a minimum is to put your smartphone into “airplane mode.” You turn your BlackBerry or iPhone into a music player and personal organizer, and you won’t be able to receive e-mail messages or make or receive phone calls, but you will stretch your battery.

“In airplane mode and running just the alarm clock, your iPhone battery will last up to a week,” said Kyle Wiens, co-founder of ifixit.com, an online iPhone and Mac laptop repair company.

The hotter your laptop feels, the more battery power it is using. And one of the biggest users of power is Flash animation, the technology behind many online videos and animated ads. To improve battery life, disable Flash when not using wall power. BashFlash and ClicktoFlash for Macs and Flashblock for PC are programs that will automatically restrict Flash.

There are a number of applications that can help monitor battery life and shut off various functions that cut down on a mobile deviceÂ’s effective power.

Battery Go and myBatteryLife tell iPhone owners how much charge they have left and how that power translates into minutes of talk time, music, video and Web surfing.

NB BattStat alerts BlackBerry owners to the amount of battery charge remaining, as well as the batteryÂ’s temperature. (Hot batteries lose power more quickly.) The device can be set to vibrate or sound when a predetermined low battery level is reached.

Radio Saver will monitor your BlackBerryÂ’s mobile coverage and shut off the deviceÂ’s mobile circuitry when you are out of range of a cellular signal.

Best BatterySaver allows owners of mobile phones using the Symbian operating system (including models from Nokia and Sony Ericsson) to create battery-saving profiles. For example, certain features can be automatically turned on when the phone is connected to a wall plug, or Bluetooth can be automatically disconnected when the battery charge drops below a certain level.

For laptops, programs like Battery Health Monitor (Mac) and Laptop Battery Power Monitor (PC) keep track of battery charge and estimate how many more times youÂ’ll be able to recharge your battery.

The older generation of nickel cadmium batteries suffered from memory issues; if you didnÂ’t fully charge and discharge one, it would hold a progressively smaller amount of juice.

TodayÂ’s lithium-ion batteries donÂ’t suffer from memory loss, so it is safe to top off a battery.

Lithium-ion batteries cannot be overcharged; a deviceÂ’s circuitry cuts off the power when they are full. However, manufacturers still recommend that a laptop not be continually connected to power once the battery is at its capacity. If a laptop wonÂ’t be used for several months, it should be stored with the battery in a 50 percent charge state.

All batteries can be fully charged and discharged for a fixed number of cycles; lithium ion batteries typically last between 300 and 500 cycles. Information on the number of cycles can be obtained at manufacturersÂ’ Web sites, or at batteryuniversity.com.

No matter how well you husband your batteryÂ’s resources, there comes a time when youÂ’ll need to send your battery to its final resting place.

Like most things nearing the end of their life, your battery will stay awake less and sleep more. “If your battery lasts only an hour after you’ve charged it,” said Anthony Magnabosco, owner of Milliamp.com, a battery replacement company, “you know its time is up.”

Germany's Energy Crisis Deepens as Local Utilities Cry for Help

Germany energy liquidity crisis is straining municipal utilities as gas and power prices surge, margin calls rise, and Russian supply cuts bite, forcing state support, interventions, and emergency financing to stabilize households and businesses.

 

Key Points

A cash squeeze on German municipal utilities as soaring gas and power prices trigger margin calls and funding gaps.

✅ Margin calls and spot-market purchases strain cash flow

✅ State liquidity lines and EU collateral support proposed

✅ Gazprom cuts, Uniper distress heighten default risks

 

Germany’s fears that soaring power prices and gas prices could trigger a deeper crisis is starting to get real. 

Several hundred local utilities are coming under strain and need support, according to the head of Germany’s largest energy lobby group. The companies, generally owned by municipalities, supply households and small businesses directly and are a key part of the country’s power and gas network.

“The next step from the government and federal states must be to secure liquidity for these municipal companies,” Kerstin Andreae, chairwoman of the German Association of Energy and Water Industries, told Bloomberg in Berlin. “Prices are rising, and they have no more money to pay the suppliers. This is a big problem.”

Germany’s energy crunch intensified over the weekend after Russia’s Gazprom PJSC halted its key gas pipeline indefinitely, a stark wake-up call for policymakers to reduce fossil fuel dependence. European energy prices have surged again amid concerns over shortages this winter and fears of a worst-case energy scenario across the bloc. 

Many utilities are running into financial issues as they’re forced to cover missing Russian deliveries with expensive supplies on the spot market. German energy giant Uniper SE, which supplies local utilities, warned it will likely burn through a 7 billion-euro ($7 billion) government safety net and will need more help already this month.

Some German local utilities have already sought help, according to a government official, who asked not to be identified in line with briefing rules.  

With Europe’s largest economy already bracing for recession, Chancellor Olaf Scholz’s administration is battling on several fronts, testing the government’s financial capacity. The ruling coalition agreed Sunday on a relief plan worth about 65 billion euros -- part of an emerging energy shield package to contain the fallout of surging costs for households and businesses. 

Starting in October, local utilities will have to pay a levy for the gas acquired, which will further increase their financial burden, Andreae said.

Margin Calls
European gas prices are more than four times higher than usual for this time of year, underscoring why rolling back electricity prices is tougher than it appears for policymakers, as Russia cuts supplies in retaliation for sanctions related to its invasion of Ukraine. When prices peak, energy companies have to pay margin calls, extra collateral required to back their trades.

The problem has hit local utilities in other countries as well. In Austria, the government approved a 2 billion-euro loan for Vienna’s municipal utility last month. 

The European Union is also planning help, floating gas price cap strategies among other tools. The bloc’s emergency measures will include support for electricity producers struggling to find enough cash to guarantee trades, according to European Commission President Ursula von der Leyen.

The situation has worsened in Germany as some of the country’s big gas importers are reluctant to sell more supplies to some of municipal companies amid fears they could default on payments, Andreae said.

German official says nuclear would do little to solve gas issue

Germany Nuclear Phase-Out drives policy amid gas supply risks, Nord Stream 1 shutdown fears, Russia dependency, and energy security planning, as Robert Habeck rejects extending reactors, favoring coal backup, storage, and EU diversification strategies.

 

Key Points

Ending Germany's last reactors by year end despite gas risks, prioritizing storage, coal backup, and EU diversification.

✅ Reactors' legal certification expires at year end

✅ Minimal gas savings from extending nuclear capacity

✅ Nord Stream 1 cuts amplify energy security risks

 

Germany’s vice-chancellor has defended the government’s commitment to ending the use of nuclear power at the end of this year, amid fears that Russia may halt natural gas supplies entirely.

Vice-Chancellor Robert Habeck, who is also the economy and climate minister and is responsible for energy, argued that keeping the few remaining reactors running would do little to address the problems caused by a possible natural gas shortfall.

“Nuclear power doesn’t help us there at all,” Habeck, said at a news conference in Vienna on Tuesday. “We have a heating problem or an industry problem, but not an electricity problem – at least not generally throughout the country.”

The main gas pipeline from Russia to Germany shut down for annual maintenance on Monday, as Berlin grew concerned that Moscow may not resume the flow of gas as scheduled.

The Nord Stream 1 pipeline, Germany’s main source of Russian gas, is scheduled to be out of action until July 21 for routine work that the operator says includes “testing of mechanical elements and automation systems”.

But German officials are suspicious of Russia’s intentions, particularly after Russia’s Gazprom last month reduced the gas flow through Nord Stream 1 by 60 percent.

Gazprom cited technical problems involving a gas turbine powering a compressor station that partner Siemens Energy sent to Canada for overhaul.

Germany’s main opposition party has called repeatedly to extend nuclear power by keeping the country’s last three nuclear reactors online after the end of December. There is some sympathy for that position in the ranks of the pro-business Free Democrats, the smallest party in Chancellor Olaf Scholz’s governing coalition.

In this year’s first quarter, nuclear energy accounted for 6 percent of Germany’s electricity generation and natural gas for 13 percent, both significantly lower than a year earlier. Germany has been getting about 35 percent of its gas from Russia.

Habeck said the legal certification for the remaining reactors expires at the end of the year and they would have to be treated thereafter as effectively new nuclear plants, complete with safety considerations and the likely “very small advantage” in terms of saving gas would not outweigh the complications.

Fuel for the reactors also would have to be procured and Scholz has said that the fuel rods are generally imported from Russia.

Opposition politicians have argued that Habeck’s environmentalist Green party, which has long strongly supported the nuclear phase-out, is opposing keeping reactors online for ideological reasons, even as some float a U-turn on the nuclear phaseout in response to the energy crisis.

Reducing dependency on Russia
Germany and the rest of Europe are scrambling to fill the gas storage in time for the northern hemisphere winter, even as Europe is losing nuclear power at a critical moment and reduce their dependence on Russian energy imports.

Prior to the Russian invasion of Ukraine, Berlin had said it considered nuclear energy dangerous and in January objected to European Union proposals that would let the technology remain part of the bloc’s plans for a climate-friendly future that includes a nuclear option for climate change pathway.

“We consider nuclear technology to be dangerous,” government spokesman Steffen Hebestreit told reporters in Berlin, noting that the question of what to do with radioactive waste that will last for thousands of generations remains unresolved.

While neighbouring France aimed to modernise existing reactors, Germany stayed on course to switch off its remaining three nuclear power plants at the end of this year and phase out coal by 2030.

Last month, Germany’s economy minister said the country would limit the use of natural gas for electricity production and make a temporary recourse to coal generation to conserve gas.

“It’s bitter but indispensable for reducing gas consumption,” Robert Habeck said.

India’s Kakrapur 3 achieves criticality

Kakrapar Unit 3 700MWe PHWR achieved first criticality, showcasing indigenously designed nuclear power, NPCIL operations, Make in India manufacturing, advanced safety systems, grid integration, and closed-fuel-cycle strategy for India's expansion of pressurised heavy water reactors.

 

Key Points

India's first indigenous 700MWe PHWR at Kakrapar reached criticality, advancing NPCIL's Make in India nuclear power.

✅ First indigenous 700MWe PHWR achieves criticality

✅ NPCIL-built, Make in India components and contractors

✅ Advanced safety: passive decay heat removal, containment spray

 

Unit 3 of India’s Kakrapar nuclear plant in Gujarat achieved criticality on 22 July, as milestones at nuclear projects worldwide continue to be reached. It is India’s first indigenously designed 700MWe pressurised heavy water reactor (PHWR) to achieve this milestone.

Prime Minister Narendra Modi congratulated nuclear scientists, saying the reactor is a shining example of the 'Make in India' campaign and of the government's steps to get nuclear back on track in recent years, and a trailblazer for many such future achievements. 

India developed its own nuclear power generation technology as it faced sanctions from the international community following its first nuclear weapons test in in 1974. It has not signed the Nuclear Non-Proliferation Treaty, while China's nuclear energy development is on a steady track according to experts. India has developed a three-stage nuclear programme based on a closed-fuel cycle, where the used fuel of one stage is reprocessed to produce fuel for the next stage.

Kakrapar 3 was developed and is operated by state-owned Nuclear Power Corporation of India Ltd (NPCIL), while in Europe KHNP considered for a Bulgarian project as countries weigh options. The first two units are 220MWe PHWRs commissioned in 1993 and 1995. NPCIL said in a statement that the components and equipment for Kakrapur 3 were “manufactured by lndian industries and the construction and erection was undertaken by various lndian contractors”.

The 700MWe PHWRs have advanced safety features such as steel lined inner containment, a passive decay heat removal system, a containment spray system, hydrogen management systems etc, the statement added.

Fuel loading was completed by mid-March, a crucial step in Abu Dhabi during its commissioning as well. “Thereafter, many tests and procedures were carried out during the lockdown period following all COVlD-19 guidelines.”

“As a next step, various experiments / tests will be conducted and power will be increased progressively, a path also followed by Barakah Unit 1 reaching 100% power before commercial operations.” Kakrapur 3 will be connected to the western grid and will be India’s 23rd nuclear power reactor.

Kakrapur 3 “is the front runner in a series of 16 indigenous 700MWe PHWRs which have been accorded administrative approval and financial sanction by the government and are at various stages of implementation”. Five similar units are under construction at Kakarapur 4, Rajasthan 7&8 and Gorakhpur1&2.

DAE said in January 2019 that India planned to put 21 new nuclear units with a combined generating capacity of 15,700MWe into operation by 2031, including ten indigenously designed PHWRs, while Bangladesh develops nuclear power with IAEA assistance.

BC announces grid development, job creation

BC Hydro Power Pathway accelerates electrification with clean energy investments, new transmission lines, upgraded substations, and renewable projects like wind and solar, strengthening the grid, supporting decarbonization, and creating jobs across British Columbia's growing economy.

 

Key Points

A $36B, 10-year BC Hydro plan to expand clean power infrastructure, accelerate electrification, and support jobs.

✅ $36B for new lines, substations, dam upgrades, and distribution

✅ Supports 10,500-12,500 jobs per year across B.C.

✅ Adds wind and solar, leveraging hydro to balance renewables

 

BC Hydro is gearing up for a decade of extensive construction to enhance British Columbia's electrical system, supporting a burgeoning clean economy and community growth while generating new employment opportunities.

Premier David Eby emphasized the necessity of expanding the electrical system for industrial growth, residential needs, and future advancements. He highlighted the role of clean, affordable energy in reducing pollution, securing well-paying jobs, and fostering economic growth.

At the B.C. Natural Resources Forum in Prince George, Premier Eby unveiled a $36-billion investment plan for infrastructure projects in communities and regions and green energy solutions to provide clean, affordable electricity for future generations.

The Power Pathway: Building BC’s Energy Future, BC Hydro’s revised 10-year capital plan, involves nearly $36 billion in investments across the province from 2024-25 to 2033-34. This marks a 50% increase from the previous plan of $24 billion and includes a substantial rise in electrification and emissions-reduction projects (nearly $10 billion, up from $1 billion).

These upcoming construction projects are expected to support approximately 10,500 to 12,500 jobs annually. The plan is set to bolster and sustain BC Hydro’s capital investments as significant projects like Site C are near completion.

The plan addresses the increasing demand for electricity due to population and housing growth, industrial development, such as a major hydrogen project, and the transition from fossil fuels to clean electricity. Key projects include constructing new high-voltage transmission lines from Prince George to Terrace, building or expanding substations in high-growth areas, and upgrading dams and generating facilities for enhanced safety and efficiency.

Minister of Energy, Mines, and Low Carbon Innovation Josie Osborne stated that this plan aims to build a clean energy future and support EV charging expansion while creating construction jobs. With BC Hydro’s capital plan allocating almost $4 billion annually for the next decade, it will drive economic growth and ensure access to clean, affordable electricity.

BC Hydro aims to add new clean, renewable energy sources like wind and solar, while acknowledging power supply challenges that must be managed as capacity grows. B.C.’s hydroelectric dams, functioning as batteries, enable the integration of intermittent renewables into the grid, providing reliable backup.

Chris O’Riley, president and CEO of BC Hydro, said the grid is one of the world’s cleanest. The new $36 billion capital plan encompasses investments in generation assets, large transmission infrastructure, and local distribution networks.

In partnership with BC Hydro, Premier Eby also announced a new streamlined approval process to expedite electrification for high-demand industries and support job creation, complementing measures like the BC Hydro rebate and B.C. Affordability Credit that help households.

Minister of Environment and Climate Change Strategy George Heyman highlighted the importance of rapid electrification in collaboration with the private sector to achieve CleanBC climate goals by 2030, including corridor charging via the BC's Electric Highway, and maintain the competitiveness of B.C. industries. The new process will streamline approvals for industrial electrification projects, enhancing efficiency and funding certainty.

Analysis: Out in the cold: how Japan's electricity grid came close to blackouts

Japan Electricity Crunch exposes vulnerabilities in a liberalised power market as LNG shortages, JEPX price spikes, snow-hit solar, and weak hedging strain energy security and retail providers amid cold snap demand and limited reserve capacity.

 

Key Points

A winter demand shock and LNG shortfalls sent JEPX to records, exposing gaps in hedging, data, and energy security.

✅ JEPX wholesale prices spiked to an all-time high

✅ LNG inventories and procurement proved insufficient

✅ Snow disabled solar; new entrants lacked hedging

 

Japan's worst electricity crunch since the aftermath of the Fukushima crisis has exposed vulnerabilities in the country's recently liberalised power market, although some of the problems appear self-inflicted.

Power prices in Japan hit record highs last month, mirroring UK peak power prices during tight conditions, as a cold snap across northeast Asia prompted a scramble for supplies of liquefied natural gas (LNG), a major fuel for the country's power plants. Power companies urged customers to ration electricity to prevent blackouts, although no outages occurred.

The crisis highlighted how many providers were unprepared for such high demand. Experts say LNG stocks were not topped up ahead of winter and snow disabled solar power farms, while China's power woes strained solar supply chains.

The hundreds of small power companies that sprang up after the market was opened in 2016 have struggled the most, saying the government does not disclose the market data they need to operate. The companies do not have their own generators, instead buying electricity on the wholesale market.

Prices on the Japan Electric Power Exchange (JEPX) hit a record high of 251 yen ($2.39) per kilowatt hour in January, equating to $2,390 per megawatt hour of electricity, above record European price surges seen recently and the highest on record anywhere in the world. One megawatt hour is roughly what an average home in the U.S. would consume over 35 days.

But the vast majority of the new, smaller companies are locked into low, fixed rates they set to lure customers from bigger players, crushing them financially during a price spike like the one in January.

More than 50 small power providers wrote on Jan. 18 to Japan's industry minister, Hiroshi Kajiyama, who oversees the power sector, asking for more accessible data on supply and demand, reserve capacity and fuel inventories.

"By organising and disclosing this information, retail electricity providers will be able to bid at more appropriate prices," said the companies, led by Looop Co.

They also called on Kajiyama to require transmission and distribution companies to pass on some of the unexpected profits from price spikes to smaller operators.

The industry ministry said it had started releasing more timely market data, and is reviewing the cause of the crunch and considering changes, echoing calls by Fatih Birol to keep electricity options open amid uncertainty.

Japan reworked its power markets after the Fukushima nuclear disaster in 2011, liberalizing the sector in 2016 while pushing for more renewables.

But Japan is still heavily reliant on LNG and coal, and only four of 33 nuclear reactors are operating. The power crisis has led to growing calls to restart more reactors.

Kazuno Power, a small retail provider controlled by a municipality of the same name in northern Japan, where abundant renewable energy is locally produced, buys electricity from hydropower stations and JEPX.

During the crunch, the company had to pay nearly 10 times the usual price, Kazuno Power president Takao Takeda said in an interview. Like most other new providers, it could not pass on the costs, lost money, and folded. The local utility has taken over its customers.

"There is a contradiction in the current system," Takeda said. "We are encouraged to locally produce power for local consumption as well as use more renewable energy, but prices for these power supplies are linked to wholesale prices, which depend on the overall power supply."

The big utilities, which receive most of their LNG on long-term contracts, blamed the power shortfall on a tight spot market and glitches at generation units.

"We were not able to buy as much supply as we wanted from the spot market because of higher demand from South Korea and China, where power cuts have tightened supply," Kazuhiro Ikebe, the head of the country's electricity federation, said recently.

Ikebe is also president of Kyushu Electric Power, which supplies the southern island of Kyushu.

Utilities took extreme measures - from burning polluting fuel oil in coal plants to scavenging the dregs from empty LNG tankers - to keep the grid from breaking down.

"There is too much dependence on JEPX for procurement," said Bob Takai, the local head of European Energy Exchange, where electricity pricing reforms are being discussed, and which started offering Japan power futures last year. He added that new entrants were not hedging against sharp price moves.

Three people, who requested anonymity because of the sensitivity of the matter, were more blunt. One called the utilities arrogant in assuming they could find LNG cargoes in a pinch. Prices were already rising as China snapped up supplies, the sources noted.

"You had volatility caused by people saying 'Oh, well, demand is going to be weak because of coronavirus impacts' and then saying 'we can rely more on solar than in the past,' but solar got snowed out," said a senior executive from one generator. "We have a problem of who is charge of energy security in Japan."

Inventories of LNG, generally about two weeks worth of supplies, were also not topped up enough to prepare for winter, a market analyst said.

The fallout from the crunch has become more apparent in recent days, with new power companies like Rakuten Inc suspending new sales and Tokyo Gas, along with traditional electricity utilities, issuing profit downgrades or withdrawing their forecasts.

Although prices have fallen sharply as temperatures warmed up slightly and more generation units have come back online, the power generator executive said, "we are not out of the woods yet."

Canadian gold mine cleans up its act with electricity

Electric mining equipment enables zero-emission, diesel-free operations at Goldcorp's Borden mine, using Sandvik battery-electric drills and LHD trucks to cut ventilation costs, noise, and maintenance while improving underground air quality.

 

Key Points

Battery-powered mining equipment replaces diesel, cutting emissions and ventilation costs in underground operations.

✅ Cuts diesel use, heat load, and noise in underground headings.

✅ Reduces ventilation infrastructure and operating expense.

✅ Improves air quality, worker health, and equipment uptime.

 

Mining operations get a lot of flack for creating environmental problems around the world. Yet they provide much of the basic material that keeps the global economy humming. Some mining companies are drilling down in their efforts to clean up their acts, exploring solutions such as recovering mine heat for power to reduce environmental impact.

As the world’s fourth-largest gold mining company Goldcorp has received its share of criticism about the impact it has on the environment.

In 2016, the Canadian company decided to do something about it. It partnered with mining-equipment company Sandvik and began to convert one of its mines into an all-electric operation, a process that is expected to take until 2021.

The efforts to build an all-electric mine began with the Sandvik DD422iE in Goldcorp’s Borden mine in Ontario, Canada.

Goldcorp's Borden mine in Borden, Ontario, CanadaGoldcorp's Borden mine in Borden, Ontario, Canada

The machine weighs 60,000 pounds and runs non-stop on a giant cord. It has a 75-kwh sodium nickel chloride battery to buffer power demands, a crucial consideration as power-hungry Bitcoin facilities can trigger curtailments during heat waves, and to move the drill from one part of the mine to another.

This electric rock-chewing machine removes the need for the immense ventilation systems needed to clean the emissions that diesel engines normally spew beneath the surface in a conventional mining operation, though the overall footprint depends on electricity sources, as regions with Clean B.C. power imports illustrate in practice.

These electric devices improve air quality, dramatically reduce noise pollution, and remove costly maintenance of internal combustion engines, Goldcorp says.

More importantly, when these electric boring machines are used across the board, it will eliminate the negative health effects those diesel drills have on miners.

“It would be a challenge to go back,” says big drill operator Adam Ladouceur.

Mining with electric equipment also removes second- or third-highest expenditure in mining, the diesel fuel used to power the drills, said Goldcorp spokesman Pierre Noel, even as industries pursue dedicated energy deals like Bitcoin mining in Medicine Hat to manage power costs. (The biggest expense is the cost of labor.)

Aside from initial cost, the electric Borden mine will save approximately $7 million ($9 million Canadian) annually just on diesel, propane and electricity.

Along with various sizes of electric drills and excavating tools, Goldcorp has started using electric powered LHD (load, haul, dump) trucks to crush and remove the ore it extracts, and Sandvik is working to increase the charging speed for battery packs in the 40-ton electric trucks which transport the ore out of the mines, while utilities add capacity with new BC generating stations coming online.
