You may not think about your water heater until you get a sales pitch urging you to replace it.

Some door-to-door sellers are going to homes and saying the rented water heater is unsafe and needs to be upgraded.

They may create the impression they're with the same firm that rents your current water heater.

Before acting, ask a few questions, such as:

• Who do you represent? What is the company's name?

• How long do I have to keep my water heater? (Some have 15-year contracts.)

• What will it cost to get out early? Is there a termination fee if I move or sell my house?

• What about installation costs? New gas water heaters often require extra venting to conform to standards adopted in 2007. Do I pay for venting or do you?

• Will you replace my hot water tank with a tankless unit? What are the benefits and the costs?

Tankless systems heat the water only when there is demand, unlike a conventional system that heats the water all day to maintain the tank at a consistent temperature.

As I said before, tankless units promise an endless supply of hot water. But that doesn't mean instant hot water.

You have to wait for the water to be heated in the basement and travel to your faucet.

Some models have a small buffer tank you can keep heated to speed the delivery of hot water. This eliminates the "cold water sandwich," which can drive you crazy when shivering in the shower.

There are those who feel the technology was oversold.

"Not a day goes by where I don't receive a call from an unhappy homeowner," said Paul MacDonald, national sales manager of Bradford White-Canada in Mississauga, which supplies storage and tankless water heater models.

"We're inundated with problems relating to improper selection or installation of tankless heaters."

Large households with high water use – running soaker tubs, multi-headed showers, washing machines and dishwashers at the same time – may be disappointed with a tankless unit.

If you want to go tankless, you can offset part of the cost with government and utility rebates.

You can get $315 from the federal ecoEnergy program and $315 from a matching provincial program. But you must get a certified energy audit before and after installation.

Enbridge offers a $300 on-bill rebate for an Energy Star-qualified gas tankless water heater if it's installed by August 31 of this year.

These rebates apply to the purchase or rental of a tankless water heater.

Bill Baird, Direct Energy's senior director of field operations, gave a cost breakdown to rent a tankless water heater. The monthly fee is $33.50, compared with $20.81 for an equivalent-sized power-vented rental tank for a family of three to four people who don't require high water flow.

When installing a tankless unit, you have to upgrade the gas and water lines going to the house, and change the venting.

About two-thirds of the installations done by Direct Energy are covered by the monthly rental fee. The remaining households will pay charges in the $500 to $600 range.

If you live in an area with high mineral content in the water, you'll need regular maintenance or water softeners – which may or may not be included in the rental fees.

Trump's Vision of U.S. Energy Dominance Faces Real-World Constraints

U.S. Energy Dominance envisions deregulation, oil and gas growth, LNG exports, pipelines, and geopolitical leverage, while facing OPEC pricing power, infrastructure bottlenecks, climate policy pressures, and accelerating renewables in global markets.

 

Key Points

U.S. policy to grow fossil fuel output and exports via deregulation, bolstering energy security, geopolitical influence.

✅ Deregulation to expand drilling, pipelines, and export capacity

✅ Exposed to OPEC pricing, global shocks, and cost competitiveness

✅ Faces infrastructure, ESG finance, and renewables transition risks

 

Former President Donald Trump has consistently advocated for “energy dominance” as a cornerstone of his energy policy. In his vision, the United States would leverage its abundant natural resources to achieve energy self-sufficiency, flood global markets with cheap energy, and undercut competitors like Russia and OPEC nations. However, while the rhetoric resonates with many Americans, particularly those in energy-producing states, the pursuit of energy dominance faces significant real-world challenges that could limit its feasibility and impact.

The Energy Dominance Vision

Trump’s energy dominance strategy revolves around deregulation, increased domestic production of oil and gas, and the rollback of climate-oriented restrictions. During his presidency, he emphasized opening federal lands to drilling, accelerating the approval of pipelines, and, through an executive order, boosting uranium and nuclear energy initiatives, as well as withdrawing from international agreements like the Paris Climate Accord. The goal was not only to meet domestic energy demands but also to establish the U.S. as a major exporter of fossil fuels, thereby reducing reliance on foreign energy sources.

This approach gained traction during Trump’s first term, with the U.S. achieving record levels of oil and natural gas production. Energy exports surged, making the U.S. a net energy exporter for the first time in decades. Yet, critics argue that this policy prioritizes short-term economic gains over long-term sustainability, while supporters believe it provides a roadmap for energy security and geopolitical leverage.

Market Realities

The energy market is complex, influenced by factors beyond the control of any single administration, with energy crisis impacts often cascading across sectors. While the U.S. has significant reserves of oil and gas, the global market sets prices. Even if the U.S. ramps up production, it cannot insulate itself entirely from price shocks caused by geopolitical instability, OPEC production cuts, or natural disasters.

For instance, despite record production in the late 2010s, American consumers faced volatile gasoline prices during an energy crisis driven by $5 gas and external factors like tensions in the Middle East and fluctuating global demand. Additionally, the cost of production in the U.S. is often higher than in countries with more easily accessible reserves, such as Saudi Arabia. This limits the competitive advantage of U.S. energy producers in global markets.

Infrastructure and Environmental Concerns

A major obstacle to achieving energy dominance is infrastructure. Expanding oil and gas production requires investments in pipelines, export terminals, and refineries. However, these projects often face delays due to regulatory hurdles, legal challenges, and public opposition. High-profile pipeline projects like Keystone XL and Dakota Access have become battlegrounds between industry proponents and environmental activists, and cross-border dynamics such as support for Canadian energy projects amid tariff threats further complicate permitting, highlighting the difficulty of reconciling energy expansion with environmental and community concerns.

Moreover, the transition to cleaner energy sources is accelerating globally, with many countries committing to net-zero emissions targets. This trend could reduce the demand for fossil fuels in the long run, potentially leaving U.S. producers with stranded assets if global markets shift more quickly than anticipated.

Geopolitical Implications

Trump’s energy dominance strategy also hinges on the belief that U.S. energy exports can weaken adversaries like Russia and Iran. While increased American exports of liquefied natural gas (LNG) to Europe have reduced the continent’s reliance on Russian gas, achieving total energy independence for allies is a monumental task. Europe’s energy infrastructure, designed for pipeline imports from Russia, cannot be overhauled overnight to accommodate LNG shipments.

Additionally, the influence of major producers like Saudi Arabia and the OPEC+ alliance remains significant, even as shifts in U.S. policy affect neighbors; in Canada, some viewed Biden as better for the energy sector than alternatives. These countries can adjust production levels to influence prices, sometimes undercutting U.S. efforts to expand its market share.

The Renewable Energy Challenge

The growing focus on renewable energy adds another layer of complexity. Solar, wind, and battery storage technologies are becoming increasingly cost-competitive with fossil fuels. Many U.S. states and private companies are investing heavily in clean energy to align with consumer preferences and global trends, amid arguments that stepping away from fossil fuels can bolster national security. This shift could dampen the domestic demand for oil and gas, challenging the long-term viability of Trump’s energy dominance agenda.

Moreover, international pressure to address climate change could limit the expansion of fossil fuel infrastructure. Financial institutions and investors are increasingly reluctant to fund projects perceived as environmentally harmful, further constraining growth in the sector.

While Trump’s call for U.S. energy dominance taps into a desire for economic growth and energy security, it faces numerous challenges. Global market dynamics, infrastructure bottlenecks, environmental concerns, and the transition to renewable energy all pose significant barriers to achieving the ambitious vision.

For the U.S. to navigate these challenges effectively, a balanced approach that incorporates both traditional energy sources and investments in clean energy is likely needed. Striking this balance will require careful policymaking that considers not just immediate economic gains but also long-term sustainability and global competitiveness.

China's Data Centers Alone Will Soon Use More Electricity Than All Of Australia

Cloud Data Centers Environmental Impact highlights massive electricity use, carbon emissions, and cooling demands, with coal-heavy grids in China; big tech shifts to renewable energy, green data centers, and cooler climates to boost sustainability.

 

Key Points

Energy use, emissions, and cooling load of cloud systems, and shifts to renewables to reduce climate impact.

✅ Global data centers use 3-5% of electricity, akin to airlines

✅ Cooling drives energy demand; siting in cool climates saves power

✅ Shift from coal to renewables lowers CO2 and improves PUE

 

A hidden environmental price makes storing data in the cloud a costly convenience.

Between 3 to 5% of all electricity used globally comes from data centers that house massive computer systems, with computing power forecasts warning consumption could climb, an amount comparable to the airline industry, says Ben Brock Johnson, Here & Now’s tech analyst.

Instead of stashing information locally on our own personal devices, the cloud allows users to free up storage space by sending photos and files to data centers via the internet.

The cloud can also use large data sets to solve problems and host innovative technologies that make cities and homes smarter, but storing information at data centers uses energy — a lot of it.

"Ironically, the phrase 'moving everything to the cloud' is a problem for our actual climate right now," Johnson says.

A new study from Greenpeace and North China Electric Power University reports that in five years, China's data centers alone will consume as much power as the total amount used in Australia in 2018. The industry's electricity consumption is set to increase by 66% over that time.

Buildings storing data produced 99 million metric tons of carbon last year in China, the study finds, with SF6 in electrical equipment compounding warming impacts, which is equivalent to 21 million cars.

The amount of electricity required to run a data center is a global problem, but in China, 73% of these data centers run on coal, even as coal-fired electricity is projected to fall globally this year.

The Chinese government started a pilot program for green data centers in 2015, which Johnson says signals the country is thinking about the environmental consequences of the cloud.

"Beijing’s environmental awareness in the last decade has really come from a visible impact of its reliance on fossil fuels," he says. "The smog of Chinese cities is now legendary and super dangerous."

The country's solar power innovations have allowed the country to surpass the U.S. in cleantech, he says.

Chinese conglomerate Alibaba Group has launched data centers powered by solar and hydroelectric power.

"While I don't know how committed the government is necessarily to making data centers run on clean technology," Johnson says. "I do think it is possible that a larger evolution of the government's feelings on environmental responsibility might impact this newer tech sector."

In the U.S., there has been a big push to make data centers more sustainable amid warnings that the electric grid is not designed for mounting climate impacts.

Canada has made notable progress decarbonizing power, with nationwide electricity gains supporting cleaner data workloads.

Apple now says all of its data centers use clean energy. Microsoft is aiming for 70% renewable energy by 2023, aligning with declining power-sector emissions as producers move away from coal.

Amazon is behind the curve, for once, with about 50%, Johnson says. Around 1,000 employees are planning to walk out on Sept. 20 in protest of the company’s failure to address environmental issues.

"Environmental responsibility fits the brand identities these companies want to project," he says. "And as large tech companies become more competitive with each other, as Apple becomes more of a service company and Google becomes a device company, they want to convince users more and more to think of them as somehow different even if they aren't."

Google and Facebook are talking about building data centers in cooler places like Finland and Sweden instead of hot deserts like Nevada, he says.

In Canada, cleaning up electricity is critical to meeting climate pledges, according to recent analysis.

Computer systems heat up and need to be cooled down by air conditioning units, so putting a data center in a warm climate will require greater cooling efforts and use more energy.

In China, 40% of the electricity used at data centers goes toward cooling equipment, according to the study.

The more data centers consolidate, Johnson says they can rely on fewer servers and focus on larger cooling efforts.

But storing data in the cloud isn't the only way tech users are unknowingly using large amounts of energy: One Google search requires an amount of electricity equivalent to powering a 60-watt light bulb for 17 seconds, magazine Yale Environment 360 reports.

"In some ways, we're making strides even as we are creating a bigger problem," he says. "Which is like, humanity's MO, I guess."

Federal net-zero electricity regulations will permit some natural gas power generation

Canada Clean Electricity Regulations allow flexible, technology-neutral pathways to a 2035 net-zero grid, permitting limited natural gas with carbon capture, strict emissions standards, and exemptions for emergencies and peak demand across provinces and territories.

 

Key Points

Federal draft rules for a 2035 net-zero grid, allowing limited gas with CCS under strict performance and compliance standards.

✅ Performance cap: 30 tCO2 per GWh annually for gas plants

✅ CCS must sequester 95% of emissions to comply

✅ Emergency and peak demand exemptions permitted

 

After facing pushback from Alberta and Saskatchewan, and amid looming power challenges nationwide, Canada's draft net-zero electricity regulations — released today — will permit some natural gas power generation. 

Environment Minister Steven Guilbeault released Ottawa's proposed Clean Electricity Regulations on Thursday.

Provinces and territories will have a minimum 75-day window to comment on the draft regulations. The final rules are intended to pave the way to a net-zero power grid in Canada, aligning with 2035 clean electricity goals established nationally. 

Calling the regulations "technology neutral," Guilbeault said the federal government believes there's enough flexibility to accommodate the different energy needs of Canada's diverse provinces and territories, including how Ontario is embracing clean power in its planning. 

"What we're talking about is not a fossil fuel-free grid by 2035; it's a net zero grid by 2035," Guilbeault said. 

"We understand there will be some fossil fuels remaining … but we're working to minimize those, and the fossil fuels that will be used in 2035 will have to comply with rigorous environmental and emission standards," he added. 

Some analysts argue that scrapping coal-fired electricity can be costly and ineffective, underscoring the trade-offs in transition planning.

While non-emitting sources of electricity — hydroelectricity, wind and solar and nuclear — should not have any issues complying with the regulations, natural gas plants will have to meet specific criteria.

Those operations, the government said, will need to emit the equivalent of 30 tonnes of carbon dioxide per gigawatt hour or less annually to help balance demand and emissions across the grid.

Federal officials said existing natural gas power plants could comply with that performance standard with the help of carbon capture and storage systems, which would be required to sequester 95 per cent of their emissions.

"In other words, it's achievable, and it is achievable by existing technology," said a government official speaking to reporters Thursday on background and not for attribution.

The regulations will also allow a certain level of natural gas power production without the need to capture emissions. Capturing emissions will be exempted during emergencies and peak periods when renewables cannot keep up with demand. 

Some newer plants might not have to comply with the rules until the 2040s, because the regulations apply to plants 20 years after they are commissioned, which dovetails with net-zero by 2050 commitments from electricity associations. 

The two-decade grace period does not apply to plants that open after the regulations are expected to be finalized in 2025.

Changes Coming For Ontario Electricity Consumers

Ontario Electricity Billing Changes include OEB-backed shifts to time-of-use or tiered pricing, landlord blanket elections, LDC implementation guidance, a customer choice webpage with a bill calculator, and ENDM rate mitigation messaging.

 

Key Points

They are OEB measures enabling TOU-to-tiered switching, landlord elections, LDC guidance, and ENDM bill messages.

✅ Option to switch from TOU to tiered pricing

✅ Landlord blanket elections on tenant turnover

✅ ENDM-led bill info and rate mitigation messaging

 

By David Stevens, Aird & Berlis LLP

Electricity consumers in Ontario may see a couple of electricity rate changes in their bills in the coming months.

First, as we have already discussed, as of November 1, 2020, regulated price plan customers will have the option to switch to "tiered pricing" instead of time-of-use (TOU) pricing structures. Those who switch to "tiered pricing" will see changes in their electricity bills.

The Ontario Energy Board (OEB) has now issued final amendments to the Standard Supply Service Code to support the customer election process necessary to switch from TOU pricing to tiered pricing. The main change from what was already published in previous OEB notices is that landlords will be permitted to make a "blanket election" between TOU pricing and tiered pricing that will apply each time a tenant's account reverts back to the landlord on turnover of the rental unit. In its most recent notice, the OEB acknowledges that implementing the new customer billing option as of Nov. 1 (less than two months from now) will be challenging and directs Local Distribution Companies (LDCs) who cannot meet this date to be immediately in touch with the OEB. Finally, the OEB indicates that there will be a dedicated "customer choice webpage for consumers, including a bill calculator" in place by early October.

Second, as of January 1, 2021 low-volume consumers will see additional messaging on their bills to inform them of available rate mitigation programs.

A recent proposal posted on Ontario's Regulatory Registry indicates that the Ministry of Energy, Northern Development and Mines (ENDM) proposes that LDCs and Utility Sub-Meter Providers will be required to include a new on-bill message for low-volume consumers that "will direct customers to ENDM's new web page for further information about how the province provides financial support to electricity consumers." This new requirement is planned to be in place as of January 1, 2021. In conjunction with this requirement, the ENDM plans to launch a new web page that will provide "up-to-date information about electricity bills," including information about rate mitigation programs available to consumers. Parties are invited to submit comments on the ENDM proposal by October 5, 2020.

WY Utility's First Wind Farm Faces Replacement

Foote Creek I Wind Farm Repowering upgrades Wyoming turbines with new nacelles, towers, and blades, cutting 68 units to 12 while sustaining 41.6 MW, under PacifiCorp and Rocky Mountain Power's Energy Vision 2020 plan.

 

Key Points

Replacement at Foote Creek Rim I, cutting to 12 turbines while sustaining about 41.6 MW using modern 2-4.2 MW units.

✅ 12 turbines replace 68, output steady near 41.6 MW

✅ New nacelles, towers, blades; taller 500 ft turbines

✅ Part of PacifiCorp Energy Vision 2020 and Gateway West

 

A Wyoming utility company has filed a permit to replace its first wind farm—originally commissioned in 1998, composed of over 65 turbines—amid new gas capacity competing with nuclear in Ohio, located at Foote Creek Rim I. The replacement would downsize the number of turbines to 12, which would still generate roughly the same energy output.

According to the Star Tribune, PacifiCorp’s new installation would involve new nacelles, new towers and new blades. The permit was filed with Carbon County.

 

New WY Wind Farm

The replacement wind turbines will stand more than twice as tall as the old: Those currently installed stand 200 feet tall, whereas their replacements will tower closer to 500 feet. Though this move is part of the company’s overall plan to expand its state wind fleet as some utilities respond to declining coal returns in the Midwest, the work going into the Foote Creek site is somewhat special, noted David Eskelsen, spokesperson for Rocky Mountain Power, the western arm of PacifiCorp.

“Foote Creek I repowering is somewhat different from the repowering projects announced in the (Energy Vision) 2020 initiative,” he said. “Foote Creek is a complete replacement of the existing 68 foundations, towers, turbine nacelles and rotors (blades).”

Currently, the turbines at Foote Creek have 600 kilowatts capacity each; the replacements’ maximum production ranges from 2 megawatts to 4.2 megawatts each, with the total output remaining steady at 41.4 megawatts, a scale similar to a 30-megawatt wind expansion in Eastern Kings, though there will be a slight capacity increase to 41.6 megawatts, according to the Star Tribune.

As part of the wind farm repowering initiative, PacifiCorp is to become full owner and operator of the Foote Creek site. When the farm was originally built, an Oregon-based water and electric board was 21 percent owner; 37 percent of the project’s output was tied into a contract with the Bonneville Power Administration.

Otherwise, PacifiCorp is moving to further expand its state wind fleet in line with initiatives like doubling renewable electricity by 2030 in Saskatchewan, with the addition of three new wind farms—to be located in Carbon, Albany and Converse counties—which may add up to 1,150 megawatts of power.

According to PacifiCorp, the company has more than 1,000 megawatts of owned wind generation capability, along with long-term purchase agreements for more than 600 megawatts from other wind farms owned by other entities. Energy Vision 2020 refers to a $3.5 billion investment and company move that is looking to upgrade the company's existing wind fleet with newer technology, adding 1,150 megawatts of new wind resources by 2020 and a a new 140-mile Gateway West transmission segment in Wyoming, comparable to a transmission project in Missouri just energized.

Gaza’s sole electricity plant shuts down after running out of fuel

Gaza Power Plant Shutdown underscores the Gaza Strip's fuel ban, Israeli blockade, and electricity crisis, cutting megawatts, disrupting hospitals and quarantine centers, and exposing fragile energy supply, GEDCO warnings, and public health risks.

 

Key Points

An abrupt halt of Gaza's sole power plant due to a fuel ban, deepening the electricity crisis and straining hospitals.

✅ Israeli fuel ban halts Gaza's only power plant

✅ Available supply drops far below 500 MW demand

✅ Hospitals and COVID-19 quarantine centers at risk

 

The only electricity plant in the Gaza Strip shut down yesterday after running out of fuel banned from entering the besieged enclave by the Israeli occupation, Gaza Electricity Distribution Company announced.

“The power plant has shut down completely,” the company said in a brief statement, as disruptions like China power cuts reveal broader grid vulnerabilities.

Israel banned fuel imports into Gaza as part of punitive measures over the launching incendiary balloons from the Strip.

On Sunday, GEDCO warned that the industrial fuel for the electricity plant would run out, mirroring Lebanon's fuel shortage challenges, on Tuesday morning.

Since 2007, the Gaza Strip suffered under a crippling Israeli blockade that has deprived its roughly two million inhabitants of many vital commodities, including food, fuel and medicine, and regional strains such as Iraq's summer electricity needs highlight broader power insecurity.

As a result, the coastal enclave has been reeling from an electricity crisis, similar to when the National Grid warned of short supply in other contexts.

The Gaza Strip needs some 500 megawatts of electricity – of which only 180 megawatts are currently available – to meet the needs of its population, while Iran supplies about 40% of Iraq's electricity in the region.

Spokesman of the Ministry of Health in Gaza, Ashraf Al Qidra, said the lack of electricity undermines offering health services across Gaza’s hospitals.

He also warned that the lack of electricity would affect the quarantine centres used for coronavirus patients, reinforcing the need to keep electricity options open during the pandemic.

Gaza currently has three sources of electricity: Israel, which provides 120 megawatts and is advancing coal use reduction measures; Egypt, which supplies 32 megawatts; and the Strip’s sole power plant, which generates between 40 and 60 megawatts.
