Is your refrigerator running?

I’m not kidding – is it?

My old refrigerator provided constant (and unpleasant) white noise throughout our house while we fretted over whether it was more “green” to keep it (and thus not contribute more waste to landfill) or to replace it with a more energy-efficient model. The refrigerator made the decision for us by dying a sudden death; its Energy Star replacement is silent and has cut our electricity bills significantly. Refrigerators – and dishwashers, washers and dryers – have gotten sleeker and more functional in recent years, the manufacturers motivated in part by late ’90s legislation that mandated 30 percent increases in energy efficiency. (Though the recent appearance of televisions in refrigerator doors gives me pause.)

But another energy-sucking appliance has fallen behind: the air conditioner.

There are many alternatives to air conditioning, from ceiling fans (there are lots of stylish ones these days, including the high design group available at Modern Fan to good old-fashioned awnings, which you may be surprised to learn can reduce household cooling energy by as much as 26 percent in hot climates and 33 percent in cold climates.

Major corporations like Credit Suisse and Morgan Stanley have ventured back even further, using blocks of ice — albeit really huge blocks of ice — to cool their corporate headquarters.

Quaint, no? But so incredibly logical. And of course, the D.I.Y. crowd are tinkering away in their respective garages to create geeky but wonderful alternatives like the one I found on the quirky site instructables.com: an air conditioner made from an ice cream box, an 80-millimeter fan and a 12-volt transformer.

But most of us simply trudge off to Best Buy or Circuit City as soon as temperatures spike and buy the most powerful thing we can afford, more concerned with sweating less than with altering the course of global warming. Air conditioners, those clunky, typically inefficient creatures, have gotten short shrift in the realm of energy efficient appliances: consumers have been well-educated about the cost- and energy-saving benefits of Energy Star-rated dishwashers, dryers and frontloading washers, but as common as central air is, the lowly air conditioner exists in our collective imagination as the hulking, droning, aesthetically challenging thing that it often still is.

A more human-centered design approach has resulted in some interesting alternatives, often focusing on maintaining a comfortable temperature for the individual rather than the whole house (or office). This approach abandons the premise of central air conditioning in favor of what is sometimes termed “personal climate control.” Both at home, where we tend to stay in certain areas for extended periods of time, and at work, where temperature control is often among the top five worker complaints, this idea makes good sense.

DeLonghi delivers a near-anthropomorphic version with the Pinguino, a compact, portable unit designed to cool only the room you are occupying.

Herman Miller, a furniture company known for its commitment to energy and waste reduction, earth-friendly materials and sustainable architecture (its Michigan headquarters were designed by the green building pioneer William McDonough), offers an even smaller device for workspaces designed to keep its owner cool - or warm, depending on the season.

Part of the company Be Collection, the tiny C2 heats and cools but uses less than 1.5 amps of AC current, which is approximately 90 percent less energy than a typical space heater.

The award for the oddest but well-intentioned attempt (and most appropriate for use in long-haul trucks and insane asylums of yore) goes to the Sleep Genie by Sun Frost. Acknowledging the challenge of cooling in hotter climates, Sun Frost proposes installing a very small air conditioner within a very small area, like the insulated space around oneÂ’s bed shown here.

Great. You may be cooler, but now youÂ’re claustrophobic.

Sun FrostÂ’s concept is not inherently different from DeLonghiÂ’s or Herman MillerÂ’s, though its execution speaks to a larger issue: a general lack of innovation. Instead of re-imagining what an air conditioner could be (something portable, something that took a different form, something that ran on an alternative energy source), they simply took the existing form and shrank it.

This seems to me indicative of so much thatÂ’s happening right now with other big-ticket items like homes and cars. Lower gas prices, for example, do not solve the problem of decreasing supply and increased demand for oil. Home designs that neglect to address things like natural light and ventilation are not contributing to quality of life, let alone reducing heating and cooling costs. The gas/driving issue requires a tremendous commitment to not only alternative fuels but alternative behaviors (i.e., walking, carpooling, mass transit); as for housing, the challenges are formidable, yet a quick look back to vernacular precedents like shotgun houses that encourage ventilation, and window orientation that encourages passive heating and cooling, would help point things in the right direction.

Victims of California's mega-fire will sue electricity company

PG&E Wildfire Lawsuit alleges utility negligence, inadequate infrastructure maintenance, and faulty transmission lines, as victims seek compensation. Regulators investigate the blaze, echoing class actions after Victoria's Black Saturday mega-fires and utility oversight failures.

 

Key Points

PG&E Wildfire Lawsuit alleges utility negligence and power line faults, seeking victim compensation amid investigations.

✅ Alleged failure to maintain transmission infrastructure

✅ Spark reports and regulator filings before blaze erupted

✅ Class action parallels with Australia's Black Saturday

 

Victims of California's most destructive wildfire have filed a lawsuit accusing Pacific Gas & Electric Co. of causing the massive blaze, a move that follows the utility's 2018 Camp Fire guilty plea in a separate case.

The suit filed on Tuesday in state court in California accuses the utility of failing to maintain its infrastructure and properly inspect and manage its power transmission lines, amid prior reports that power lines may have sparked fires in California.

The utility's president said earlier the company doesn't know what caused the fire, but is cooperating with the investigation by state agencies, and other utilities such as Southern California Edison have faced wildfire lawsuits in California.

PG&E told state regulators last week that it experienced a problem with a transmission line in the area of the fire just before the blaze erupted.

A landowner near where the blaze began said PG&E notified her the day before the wildfire that crews needed to come onto her property because some wires were sparking, and the company later promoted its wildfire assistance program for victims seeking aid.

A massive class action after Australia's last mega-fire, Victoria's Black Saturday in 2009, saw $688.5 million paid in compensation to thousands of claimants affected by the Kilmore-Kinglake and Murrindindi-Marysville fires, partly by electricity company SP Ausnet, and partly by government agencies, while in California PG&E's bankruptcy plan won support from wildfire victims addressing compensation claims.

Tracking Progress on 100% Clean Energy Targets

100% Clean Energy Targets drive renewable electricity, decarbonization, and cost savings through state policies, CCAs, RECs, and mandates, with timelines and interim goals that boost jobs, resilience, and public health across cities, counties, and utilities.

 

Key Points

Policies for cities and states to reach 100% clean power by set dates, using mandates, RECs, and interim goals.

✅ Define eligible clean vs renewable resources

✅ Mandate vs goal framework with enforcement

✅ Timelines with interim targets and escape clauses

 

“An enormous amount of authority still rests with the states for determining your energy future. So we can build these policies that will become a postcard from the future for the rest of the country,” said David Hochschild, chair of the California Energy Commission, speaking last week at a UCLA summit on state and local progress toward 100 percent clean energy.

According to a new report from the UCLA Luskin Center for Innovation, 13 states, districts and territories, as well as more than 200 cities and counties, with standout clean energy purchases by Southeast cities helping drive momentum, have committed to a 100 percent clean electricity target — and dozens of cities have already hit it.

This means that one of every three Americans, or roughly 111 million U.S. residents representing 34 percent of the population, live in a community that has committed to or has already achieved 100 percent clean electricity, including communities like Frisco, Colorado that have set ambitious targets.

“We’re going to look back on this moment as the moment when local action and state commitments began to push the entire nation toward this goal,” said J.R. DeShazo, director of the UCLA Luskin Center for Innovation.

Not all 100 percent targets are alike, however. The report notes that these targets vary based on 1) what resources are eligible, 2) how binding the 100 percent target is, and 3) how and when the target will be achieved.

These distinctions will carry a lot of weight as the policy discussion shifts from setting goals to actually meeting targets. They also have implications for communities in terms of health benefits, cost savings and employment opportunities.

 

100% targets come in different forms

One key attribute is whether a target is based on "renewable" or "clean" energy resources. Some 100 percent targets, like Hawaii’s and Rhode Island’s 2030 plan, are focused exclusively on renewable energy, or sources that cannot be depleted, such as wind, solar and geothermal. But most jurisdictions use the broader term “clean energy,” which can also include resources like large hydroelectric generation and nuclear power.

States also vary in their treatment of renewable energy certificates, used to track and assign ownership to renewable energy generation and use. Unbundled RECs allow for the environmental attributes of the renewable energy resource to be purchased separately from the physical electricity delivery.

The binding nature of these targets is also noteworthy. Seven states, as well as Puerto Rico and the District of Columbia, have passed 100 percent clean energy transition laws. Of the jurisdictions that have passed 100 percent legislation, all but one specifies that the target is a “mandate,” according to the report. Nevada is the only state to call the target a “goal.”

Governors in four other states have signed executive orders with 100 percent clean energy goals.

Target timelines also vary. Washington, D.C. has set the most ambitious target date, with a mandate to achieve 100 percent renewable electricity by 2032. Other states and cities have set deadline years between 2040 and 2050. All "100 percent" state laws, and some city and county policies, also include interim targets to keep clean energy deployment on track.

In addition, some locations have included some form of escape clause. For instance, Salt Lake City, which last month passed a resolution establishing a goal of powering the county with 100 percent clean electricity by 2030, included “exit strategies” in its policy in order to encourage stakeholder buy-in, said Mayor Jackie Biskupski, speaking last week at the UCLA summit.

“We don’t think they’ll get used, but they’re there,” she said.

Other locales, meanwhile, have decided to go well beyond 100 percent clean electricity. The State of California and 44 cities have set even more challenging targets to also transition their entire transportation, heating and cooling sectors to 100 percent clean energy sources, and proposals like requiring solar panels on new buildings underscore how policy can accelerate progress across sectors.

Businesses are simultaneously electing to adopt more clean and renewable energy. Six utilities across the United States have set their own 100 percent clean or carbon-free electricity targets. UCLA researchers did not include populations served by these utilities in their analysis of locations with state and city 100 percent clean commitments.

 

“We cannot wait”

All state and local policies that require a certain share of electricity to come from renewable energy resources have contributed to more efficient project development and financing mechanisms, which have supported continued technology cost declines and contributed to a near doubling of renewable energy generation since 2008.

Many communities are switching to clean energy in order to save money, now that the cost calculation is increasingly in favor of renewables over fossil fuels, as more jurisdictions get on the road to 100% renewables worldwide. Additional benefits include local job creation, cleaner air and electricity system resilience due to greater reliance on local energy resources.

Another major motivator is climate change. The electricity sector is responsible for 28 percent of U.S. greenhouse gas emissions, second only to transportation. Decarbonizing the grid also helps to clean up the transportation sector as more vehicles move to electricity as their fuel source.

“The now-constant threat of wildfires, droughts, severe storms and habitat loss driven by climate change signals a crisis we can no longer ignore,” said Carla Peterman, senior vice president of regulatory affairs at investor-owned utility Southern California Edison. “We cannot wait and we should not wait when there are viable solutions to pursue now.”

Prior to joining SCE on October 1, Peterman served as a member of the California Public Utilities Commission, which implements and administers renewable portfolio standard (RPS) compliance rules for California’s retail sellers of electricity. California’s target requires 60 percent of the state’s electricity to come from renewable energy resources by 2030, and all the state's electricity to come from carbon-free resources by 2045.  

 

How CCAs are driving renewable energy deployment

One way California communities are working to meet the state’s ambitious targets is through community-choice aggregation, especially after California's near-100% renewable milestone underscored what's possible, via which cities and counties can take control of their energy procurement decisions to suit their preferences. Investor-owned utilities no longer purchase energy for these jurisdictions, but they continue to operate the transmission and distribution grid for all electricity users.                           

A second paper released by the Luskin Center for Innovation in recent days examines how community-choice aggregators are affecting levels of renewable energy deployment in California and contributing to the state’s 100 percent target.

The paper finds that 19 CCAs have launched in California since 2010, growing to include more than 160 towns, cities and counties. Of those communities, 64 have a 100 percent renewable or clean energy policy as their default energy program.

Because of these policies, the UCLA paper finds that “CCAs have had both direct and indirect effects that have led to increases in the clean energy sold in excess of the state’s RPS.”

From 2011 to 2018, CCAs directly procured 24 terawatt-hours of RPS-eligible electricity, 11 TWh of which have been voluntary or in excess of RPS compliance, according to the paper.

The formation of CCAs has also had an indirect effect on investor-owned utilities. As customers have left investor-owned utilities to join CCAs, the utilities have been left holding contracts for more renewable energy than they need to comply with California’s clean energy targets, amid rising solar and wind curtailments that complicate procurement decisions. UCLA researchers estimate that this indirect effect of CCA formation has left IOUs holding 13 terawatt-hours in excess of RPS requirements.

The paper concludes that CCAs have helped to accelerate California’s ability to meet state renewable energy targets over the past decade. However, the future contributions of CCAs to the RPS are more uncertain as communities make new power-purchasing decisions and utilities seek to reduce their excess renewable energy contracts.

“CCAs offer a way for communities to put their desire for clean energy into action. They're growing fast in California, one of only eight states where this kind of mechanism is allowed," said UCLA's Kelly Trumbull, an author of the report. "State and federal policies could be reformed to better enable communities to meet local demand for renewable energy.”

Electricity rates are about to change across Ontario

Ontario Electricity Rate Changes lower OEB Regulated Price Plan costs, adjust Time-of-Use winter hours and tiered thresholds, and modify the Ontario Electricity Rebate, affecting off-peak, mid-peak, and on-peak pricing for households and small businesses.

 

Key Points

OEB updates lowering RPP prices, shifting TOU hours, adjusting tiers, and modifying the Ontario Electricity Rebate.

✅ Winter TOU: Off-peak 7 p.m.-7 a.m.; weekends, holidays all day.

✅ Tiered pricing adds 400 kWh at lower rate for residential users.

✅ Ontario Electricity Rebate falls to 11.7% from 17% on Nov 1.

 

Electricity rates are about to change for consumers across Ontario.

On November 1, households and small businesses will see their electricity rates go down under the Ontario Energy Board's (OEB) Regulated Price Plan framework.

Customer's on the OEB's tiered pricing plan will also see their bills lowered on November 1, a shift from the 2021 increase when fixed pricing ended, as winter time-of-use hours and the seasonal change in the killowatt-hour threshold take effect.

Off-peak time-of-use hours will run from 7 p.m. to 7 a.m. during weekdays, including the ultra-low overnight rates option for some customers, and all day on weekends and holidays. On-peak hours will be from 7 a.m. to 11 a.m. and 5 p.m. to 7 p.m. on weekdays, and mid-peak hours from 11 a.m. to 5 p.m. on weekdays.

The winter-tier threshold provides residential customers with an extra 400 kilowatt-hours per month at a lower price during the colder weather, alongside the off-peak price freeze in effect.

The Ontario Electricity Rebate - a pre-tax credit that shows up at the bottom of electricity bills - will also see changes as a hydro rate change takes effect on November 1. Starting next month, the rebate will drop from 17 per cent to 11.7 per cent.

For a typical residential customer, the credit will decrease electricity bills by about $13.91 per month, according to the OEB.

Under the board's winter disconnection ban, electricity providers can't turn off a residential customer's power between November 15, 2022 and April 30, 2023 for failing to pay, and earlier pandemic relief included a fixed COVID-19 hydro rate for customers.

FERC needs to review capacity market performance, GAO recommends

FERC Capacity Markets face scrutiny as GAO flags inconsistent data on resource adequacy and costs, urging performance goals, risk assessment, and better metrics across PJM, ISO-NE, NYISO, and MISO amid cost-recovery proposals.

 

Key Points

FERC capacity markets aim for resource adequacy, but GAO finds weak data and urges goals and performance reviews.

✅ GAO cites inconsistent data on resource adequacy and costs

✅ Calls for performance goals, metrics, and risk assessment

✅ Applies to PJM, ISO-NE, NYISO; MISO market is voluntary

 

Capacity markets may or may not be functioning properly, but FERC can't adequately make that determination, according to the GAO report.

"Available information on the level of resource adequacy ... and related costs in regions with and without capacity markets is not comprehensive or consistent," the report found. "Moreover, consistent data on historical trends in resource adequacy and related costs are not available for regions without capacity markets."

The review concluded that FERC collects some useful information in regions with and without capacity markets, but GAO said it "identified problems with data quality, such as inconsistent data."

GAO included three recommendations, including calling for FERC to take steps to improve the quality of data collected, and regularly assess the overall performance of capacity markets by developing goals for those assessments.

"FERC should develop and document an approach to regularly identify, assess, and respond to risks that capacity markets face," the report also recommended. The commission "has not established performance goals for capacity markets, measured progress against those goals, or used performance information to make changes to capacity markets as needed."

The recommendation comes as the agency is grappling with a controversial proposal to assure cost-recovery for struggling coal and nuclear plants in the power markets. So far, the proposal would only apply to power markets with capacity markets, including PJM Interconnection, the New England ISO, the New York ISO and possibly MISO. However MISO only has a voluntary capacity market, making it unclear how the proposed rule would be applied there.

Solar farm the size of 313 football fields to be built at Edmonton airport

Airport City Solar Edmonton will deliver a 120-megawatt, 627-acre photovoltaic, utility-scale renewable energy project at EIA, creating jobs, attracting foreign investment, and supplying clean power to Fortis Alberta and airport distribution systems.

 

Key Points

A 120 MW, 627-acre photovoltaic solar farm at EIA supplying clean power to Fortis Alberta and airport systems.

✅ 120 MW utility-scale project over 627 acres at EIA

✅ Feeds Fortis Alberta and airport distribution networks

✅ Drives jobs, investment, and regional sustainability

 

A European-based company is proposing to build a solar farm bigger than 300 CFL football fields at Edmonton's international airport, aligning with Alberta's red-hot solar growth seen across the province.

Edmonton International Airport and Alpin Sun are working on an agreement that will see the company develop Airport City Solar, a 627-acre, 120-megawatt solar farm that reflects how renewable power developers combine resources for stronger projects on what is now a canola field on the west side of the airport lands.

The solar farm will be the largest at an airport anywhere in the world, EIA said in a news release Tuesday, in a region that also hosts the largest rooftop solar array at a local producer.

"It's a great opportunity to drive economic development as well as be better for the environment," Myron Keehn, vice-president, commercial development and air service at EIA, told CBC News, even as Alberta faces challenges with solar expansion that require careful planning.

"We're really excited that [Alpin Sun] has chosen Edmonton and the airport to do it. It's a great location. We've got lots of land, we're geographically located north, which is great for us, because it allows us to have great hours of sunlight.

"As everyone knows in Edmonton, you can golf early in the morning or golf late at night in the summertime here. And in wintertime it's great, because of the snow, and the reflective [sunlight] off the snow that creates power as well."

Airport official Myron Keehn says the field behind him will become home to the world's largest solar farm at an airport. (Scott Neufeld/CBC)

The project will "create jobs, provide sustainable solar power for our region and show our dedication to sustainability," Tom Ruth, EIA president and CEO, said in the news release, while complementing initiatives by Ermineskin First Nation to expand Indigenous participation in electricity generation.

Construction is expected to begin in early 2022, as new solar facilities in Alberta demonstrate lower costs than natural gas. The solar farm would be operational by the end of that year, the release said. 

Alpin Sun says the project will bring in $169 million in foreign investment to the Edmonton metro region amid federal green electricity contracts that are boosting market certainty. 

Power generated by Airport City Solar will feed into Fortis Alberta and airport distribution systems.

NTPC bags order to supply 300 MW electricity to Bangladesh

NTPC Bangladesh Power Supply Tender sees NVVN win 300 MW, long-term cross-border electricity trade to BPDB, enabled by 500 MW HVDC interconnection; rivals included Adani, PTC, and Sembcorp in the competitive bidding process.

 

Key Points

It is NTPC's NVVN win to supply 300 MW to Bangladesh's BPDB for 15 years via a 500 MW HVDC link.

✅ NVVN selected as L1 for short and long-term supply

✅ 300 MW to BPDB; delivery via India-Bangladesh HVDC link

✅ Competing bidders: Adani, PTC, Sembcorp

 

NTPC, India’s biggest electricity producer in a nation that is now the third-largest electricity producer globally, on Tuesday said it has won a tender to supply 300 megawatts (MW) of electricity to Bangladesh for 15 years.

Bangladesh Power Development Board (BPDP), in a market where Bangladesh's nuclear power is expanding with IAEA assistance, had invited tenders for supply of 500 MW power from India for short term (1 June, 2018 to 31 December, 2019) and long term (1 January, 2020 to 31 May, 2033). NTPC Vidyut Vyapar Nigam (NVVN), Adani Group, PTC and Singapore-bases Sembcorp submitted bids by the scheduled date of 11 January.

Financial bid was opened on 11 February, the company said in a statement, amid rising electricity prices domestically. “NVVN, wholly-owned subsidiary of NTPC Limited, emerged as successful bidder (L1), both in short term and long term for 300 MW power,” it said.

Without giving details of the rate at which power will be supplied, NTPC said supply of electricity is likely to commence from June 2018 after commissioning of 500 MW HVDC inter-connection project between India and Bangladesh, and as the government advances nuclear power initiatives to bolster capacity in the sector. India currently exports approximately 600 MW electricity to Bangladesh even as authorities weigh coal rationing measures to meet surging demand domestically.
