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.

Leading Offshore Wind Conference to Launch National Job Fair

OSW CareerMatch Offshore Wind Job Fair convenes industry leaders, supply chain employers, and skilled candidates at IPF 2020 in Providence, Rhode Island, spotlighting workforce development, training programs, and near-term hiring for U.S. offshore wind projects.

 

Key Points

An IPF 2020 job fair connecting offshore wind employers, advancing workforce development in Providence, RI.

✅ National job fair at IPF 2020, Providence, RI

✅ Connects supply chain employers with skilled candidates

✅ Includes a workforce development and education summit

 

The Business Network for Offshore Wind, the leading non-profit advocate for U.S. offshore wind at the state, federal and global levels, amid a U.S. grid warning about coronavirus impacts, will host its seventh annual International Partnership Forum (IPF) on April 21-24, 2020 in Providence, Rhode Island. 

New this year: the first-ever national offshore wind industry job fair plus a half-day workforce development summit, in partnership with Skills for Rhode Island’s Future. The OSW CareerMatch, will showcase jobs at top-tier companies seeking to grow the workforce of the future, informed by young people's interest in electricity careers, and recruit qualified candidates. The Offshore Wind Workforce Development and Education Summit, an invitation-only event, will bring together educators, stakeholders, and industry leaders to address current energy training programs, identify industry employment needs, required skillsets, and how organizations can fulfill these near-term needs. CareerMatch will take place 8:30 a.m. to 1:00 p.m. on Tuesday, April 21, and the Workforce Summit from 12:30 p.m. to 4:00 p.m., both at the Rhode Island Convention Center. 

“The U.S. offshore wind industry has reached the stage that, in order to successfully develop and meet new project demands, will require an available and qualified workforce,” said Liz Burdock, CEO and president of the Business Network for Offshore Wind, noting worker safety concerns in other energy sectors. “This first-ever national Job Fair will allow top-tier supply chain companies to connect with skilled individuals to discuss projects that are going on as they speak.” 

“Hosting the first-of-its-kind offshore wind energy job fair in The Ocean State is apropos,” said Nina Pande, executive director of Skills for Rhode Island’s Future, as future of work investments accelerate across the electricity sector. “Our organization is thrilled to have the unique opportunity to help convene talent at OSW CareerMatch to engage with the employers across the offshore wind supply chain.”

The annual IPF conference is the premier event for the offshore wind supply chain, which is now projected to be a $70 billion revenue opportunity through 2030. Fully developing this supply chain will foster local economic growth, provide thousands of jobs, adapt to shifts like working from home electricity demand, and help offshore wind energy meet its potential. If fully built out worldwide, offshore wind could power 18 times the world’s current electricity needs.    

The exhibit and conference sells out every year and is again on track to draw over 2,500 industry professionals representing over 575 companies, all focused on sharing valuable insights on how to move the emerging U.S. wind industry forward, including operational resilience such as on-site staffing plans during the outbreak. The full conference schedule may be seen online here. More details, including special guest speakers, will be announced soon.

Global electric power demand surges above pre-pandemic levels

Global Power Sector CO2 Surge 2021 shows electricity demand outpacing renewable energy, with coal and fossil fuels rebounding, undermining green recovery goals and climate change targets flagged by the IEA and IPCC.

 

Key Points

Record rise in power sector CO2 in 2021 as demand outpaced renewables and coal rebounded, undermining a green recovery.

✅ Electricity demand rose 5% above pre-pandemic levels

✅ Fossil fuels supplied 61% of power; coal led the rebound

✅ Wind and solar grew 15% but lagged demand

 

Carbon dioxide emissions from the global electric power sector surged past pre-pandemic levels to record highs in the first half of 2021, according to new research by London-based environmental think tank Ember.

Electricity demand and emissions are now 5% higher than where they were before the Covid-19 outbreak, which prompted worldwide lockdowns that led to a temporary drop in global greenhouse gas emissions. Electricity demand also surpassed the growth of renewable energy, and surging electricity demand is putting power systems under strain, the analysis found.

The findings signal a failure of countries to achieve a so-called “green recovery” that would entail shifting away from fossil fuels toward renewable energy, though European responses to Covid-19 have accelerated the electricity system transition by about a decade, to avoid the worst consequences of climate change.

The report found that 61% of the world’s electricity still came from fossil fuels in 2020. Five G-20 countries had more than 75% of their electricity supplied from fossil fuels last year, with Saudi Arabia at 100%, South Africa at 89%, Indonesia at 83%, Mexico at 75% and Australia at 75%.

Coal generation did fall a record 4% in 2020, but overall coal supplied 43% of the additional energy demand between 2019 and 2020, with soaring electricity and coal use underscoring persistent demand pressures. Asia currently generates 77% of the world’s coal electricity and China alone generates 53%, up from 44% in 2015.

The world’s transition out of coal power, which contributes to roughly 30% of the world’s greenhouse gas emissions, is happening far too slowly to avoid the worst impacts of climate change, the study warned. And the International Energy Agency forecasts coal generation will rebound in 2021 as electricity demand picks up again, even as renewables are poised to eclipse coal by 2025 according to other analyses.

“Progress is nowhere near fast enough. Despite coal’s record drop during the pandemic, it still fell short of what is needed,” Ember lead analyst Dave Jones said in a statement.

Jones said coal power usage must collapse by 80% by the end of the decade to avoid dangerous levels of global warming above 1.5 degrees Celsius (2.7 degrees Fahrenheit).

“We need to build enough clean electricity to simultaneously replace coal and electrify the global economy,” Jones said. “World leaders have yet to wake up to the enormity of the challenge.”

The findings come ahead of a major U.N. climate conference in Glasgow, Scotland, in November, where negotiators will push for more ambitious climate action and emissions reduction pledges from nations.

Without immediate, rapid and large-scale reductions to global emissions, scientists of the Intergovernmental Panel on Climate Change warn that the average global temperature will likely cross the 1.5 degrees Celsius threshold within 20 years.

The study also highlighted some upsides. Wind and solar generation, for instance, rose by 15% in 2020, and low-emissions sources are set to cover almost all the growth in global electricity demand in the next three years, producing nearly a tenth of the world’s electricity last year and doubling production since 2015.

Some countries now get about 10% of their electricity from wind and solar, including India, China, Japan, Brazil. The U.S. and Europe have experienced the biggest growth in wind and solar, and in the EU, wind and solar generated more electricity than gas last year, with Germany at 33% and the U.K. leads the G20 for wind power at 29%.

Poland’s largest power group opts to back wind over nuclear

Poland Offshore Wind Energy accelerates as PGE exits nuclear leadership, PKN Orlen steps in, and Baltic Sea projects expand to cut coal reliance, meet EU emissions goals, attract investors, and bridge the power capacity gap.

 

Key Points

A shift from coal and nuclear to Baltic offshore wind to add capacity, cut EU emissions, and attract investment.

✅ PGE drops lead in nuclear; pivots $10bn to offshore wind.

✅ PKN Orlen may assume nuclear role; projects await approval.

✅ 6 GW offshore could add 60b zlotys and 77k jobs by 2030.

 

PGE, Poland’s biggest power group has decided to abandon a role in building the country’s first nuclear power plant and will instead focus investment on offshore wind energy.

Reuters reports state-run refiner PKN Orlen (PKN.WA) could take on PGE’s role, while the latter announces a $10bn offshore wind power project.

Both moves into renewables and nuclear represent a major change in Polish energy policy, diversifying away from the country’s traditional coal-fired power base, as regional efforts like the North Sea wind farms initiative expand, in a bid to fill an electricity shortfall and meet EU emission standards.

An unnamed source told the news agency, PGE could not fund both projects and cheap technology had swung the decision in favour of wind, with offshore wind competing with gas in some markets. PGE could still play a smaller role in the nuclear project which has been delayed and still needs government approval.

#google#

A proposed law is currently before the Polish parliament aiming at facilitating easy construction of wind turbines, mindful of Germany’s grid expansion challenges that have hindered rollout.

If the law is passed, as expected, several other wind farm projects could also proceed.

Polenergia has said it would like to build a wind farm in the Baltic by 2022. PKN Orlen is also considering building one.

PGE said in March that it wants to build offshore windfarms with a capacity of 2.5 gigawatts (GW) by 2030.

Analysts and investors say that offshore wind farms are the easiest and fastest way for Poland to fill the expected capacity gap from coal, with examples like the largest UK offshore wind farm coming online underscoring momentum, and reduce CO2 emissions in line with EU’s 2030 targets as Poland seeks improved ties with Brussels.

The decision to open up the offshore power industry could also draw in investors, as shown by Japanese utilities’ UK offshore investment attracting cross-border capital. Statoil said in April it would join Polenergia’s offshore project which has drawn interest from other international wind companies. “

The Polish Wind Energy Association (PWEA) estimates that offshore windfarms with a total capacity of 6 GW would help create around 77,000 new jobs and add around 60 billion zlotys to economic growth.

Cancelling Ontario's wind project could cost over $100M, company warns

White Pines Project cancellation highlights Ontario's wind farm contract dispute in Prince Edward County, involving IESO approvals, Progressive Conservatives' legislation, potential court action, and costs to ratepayers amid green energy policy shifts.

 

Key Points

The termination effort for Ontario's White Pines wind farm contract, triggering legal, legislative, and cost disputes.

✅ Contract with IESO dates to 2009; final approval during election

✅ PCs seek legislation insulating taxpayers from litigation

✅ Cancellation could exceed $100M; cost impact on ratepayers

 

Cancelling an eastern Ontario green energy project that has been under development for nearly a decade could cost more than $100 million, the president of the company said Wednesday, warning that the dispute could be headed to the courts.

Ontario's governing Progressive Conservatives said this week that one of their first priorities during the legislature's summer sitting would be to cancel the contract for the White Pines Project in Prince Edward County.

Ian MacRae, president of WPD Canada, the company behind the project, said he was stunned by the news given that the project is weeks away from completion.

"What our lawyers are telling us is we have a completely valid contract that we've had since 2009 with the (Independent Electricity System Operator). ... There's no good reason for the government to breach that contract," he said.

The government has also not reached out to discuss the cancellation, he said. Meanwhile, construction on the site is in full swing, he said.

"Over the last couple weeks we've had an average of 100 people on site every day," he said. "The footprint of the project is 100 per cent in. So, all the access roads, the concrete for the base foundations, much of the electrical infrastructure. The sub-station is nearing completion."

The project includes nine wind turbines meant to produce enough electricity to power just over 3,000 homes annually, even as Ontario looks to build on an electricity deal with Quebec for additional supply. All of the turbines are expected to be installed over the next three weeks, with testing scheduled for the following month.

MacRae couldn't say for certain who would have to pay for the cancellation, electricity ratepayers or taxpayers.

"Somehow that money would come from IESO and it would be my assumption that would end up somehow on the ratepayers, despite legislation to lower electricity rates now in place," he said. "We just need to see what the government has in mind and who will foot the bill."

Progressive Conservative house leader Todd Smith, who represents the riding where the project is being built, said the legislation to cancel the project will also insulate taxpayers from domestic litigation over the dismantling of green energy projects.

"This is something that the people of Prince Edward County have been fighting ... for seven years," he said. "This shouldn't have come as a surprise to anybody that this was at the top of the agenda for the incoming government, which has also eyed energy independence in recent decisions."

Smith questioned why Ontario's Independent Electricity System Operator gave the final approval for the project during the spring election campaign.

"There's a lot of questions about how this ever got greenlighted in the first place," he said. "This project was granted its notice to proceed two days into the election campaign ... when (the IESO) should have been in the caretaker mode."

Terry Young, the IESO's vice president of policy, engagement and innovation, said the agency could not comment because of the pending introduction of legislation to cancel the deal, following a recent auditor-regulator dispute that drew attention to oversight.

NDP Leader Andrea Horwath said the new Tory government is behaving like the previous Liberal government by cancelling energy projects and tearing up contracts amid ongoing debates over Ontario's hydro mess and affordability. She likened the Tory plan to the Liberal gas plant scandal that saw the government relocate two plants at a substantial cost to taxpayers.

ETP 2017 maps major transformations in energy technologies

Global Energy Electrification drives IEA targets as smart grids, storage, EVs, and demand-side management scale. Paris Agreement-aligned policies and innovation accelerate decarbonization, enabling flexible, low-carbon power systems and net-zero pathways by 2060.

 

Key Points

A shift to electricity across sectors via smart grids, storage, EVs, and policy to cut CO2 and improve energy security.

✅ Smart grids, storage, DSM enable flexible, resilient power.

✅ Aligns with IEA pathways and Paris Agreement goals.

✅ Drives EV adoption, building efficiency, and net-zero by 2060.

 

The global energy system is changing, with European electricity market trends highlighting rapid shifts. More people are connecting to the grid as living standards improve around the world. Demand for consumer appliances and electronic devices is rising. New and innovative transportation technologies, such as electric vehicles and autonomous cars are also boosting power demand.

The International Energy Agency's latest report on energy technologies outlines how these and other trends as well as technological advances play out in the next four decades to reshape the global energy sector.

Energy Technology Perspectives 2017 (ETP) highlights that decisive policy actions and market signals will be needed to drive technological development and benefit from higher electrification around the world. Investments in stronger and smarter infrastructure, including transmission capacity, storage capacity and demand side management technologies such as demand response programs are necessary to build efficient, low-carbon, integrated, flexible and robust energy system. 

Still, current government policies are not sufficient to achieve long-term global climate goals, according to the IEA analysis, and warnings about falling global energy investment suggest potential supply risks as well. Only 3 out of 26 assessed technologies remain “on track” to meet climate objectives, according to the ETP’s Tracking Clean Energy Progress report. Where policies have provided clean signals, progress has been substantial. However, many technology areas suffer from inadequate policy support. 

"As costs decline, we will need a sustained focus on all energy technologies to reach long-term climate targets," said IEA Executive Director Dr Fatih Birol. "Some are progressing, but too few are on track, and this puts pressure on others. It is important to remember that speeding the rate of technological progress can help strengthen economies, boost energy security while also improving energy sustainability."

ETP 2017’s base case scenario, known as the Reference Technology Scenario (RTS), takes into account existing energy and climate commitments, including those made under the Paris Agreement. Another scenario, called 2DS, shows a pathway to limit the rise of global temperature to 2ºC, and finds the global power sector could reach net-zero CO2 emissions by 2060.

A second decarbonisation scenario explores how much available technologies and those in the innovation pipeline could be pushed to put the energy sector on a trajectory beyond 2DS. It shows how the energy sector could become carbon neutral by 2060 if known technology innovations were pushed to the limit. But to do so would require an unprecedented level of policy action and effort from all stakeholders.

Looking at specific sectors, ETP 2017 finds that buildings could play a major role in supporting the energy system transformation. High-efficiency lighting, cooling and appliances could save nearly three-quarters of today’s global electricity demand between now and 2030 if deployed quickly. Doing so would allow a greater electrification of the energy system that would not add burdens on the system. In the transportation system, electrification also emerges as a major low-carbon pathway, with clean grids and batteries becoming key areas to watch in deployment.

The report finds that regardless of the pathway chosen, policies to support energy technology innovation at all stages, from research to full deployment, alongside evolving utility trends that operators need to watch, will be critical to reap energy security, environmental and economic benefits of energy system transformations. It also suggests that the most important challenge for energy policy makers will be to move away from a siloed perspective towards one that enables systems integration.

Notley announces plans to move Alberta's electricity grid to net-zero by 2035 if elected

Alberta NDP Net-Zero Electricity Plan targets a 2035 clean grid, expands renewable energy, cuts emissions, creates jobs, and boosts economic diversification and rural connectivity, aligning Alberta with Canada's 2050 climate goals.

 

Key Points

A policy to achieve a net-zero electricity grid by 2035, advance renewable energy, cut emissions, and grow jobs.

✅ Net-zero electricity grid target set for 2035

✅ Scales renewable energy and emissions reductions

✅ Focus on jobs, rural connectivity, and diversification

 

Ahead of the NDP’s weekend convention, Alberta’s Opposition leader has committed to transforming the province’s energy sector and moving the province’s electricity grid to net-zero by 2035, despite debate over the federal 2035 net-zero electricity grid target in other provinces, should an orange crush wash over Alberta in the next election.

NDP Leader Rachel Notley said they would achieve this as part of the path towards Canada’s 2050 net-zero emissions goal, aligning with broader clean grids trends, which will help preserve and create jobs in the province.

“I think it’s an important goal. It’s a way of framing the work that we’re going to do within our energy industry and our energy sector, including how Alberta produces and pays for electricity going forward,” said Notley. “We know the world is moving toward different objectives and we still have the ability to lead on that front, but we need to lay down the markers early and focus on reaching those goals.”

Premier Jason Kenney has previously called the 2050 target “aspirational,” and, as the electricity sector faces profound change in Alberta, Notley said, once the work begins, it’s likely they would meet the objective earlier than proposed to reduce greenhouse gas emissions that contribute to global warming.

This is just one key issue that will be addressed at the party’s online convention, which is the first since the NDP’s defeat by the UCP in the last provincial election. Notley said other key issues will address economic diversification, economic recovery, job creation and social issues, as Alberta’s electricity market is headed for a reshuffle too. The focus, as she puts it, is “jobs, jobs, jobs.”

Attendees will also debate more than 140 policy resolutions over the weekend, including the development of a safe supply drug policy, banning coal mining in the Rocky Mountains and providing paid sick leave for workers.

Outside the formal agenda, debate over electricity market competition continues in Alberta as stakeholders weigh options.

Notley said an area of growing focus for the NDP will be rural Alberta, which is typically a conservative stronghold. One panel presentation during the convention will focus on connecting and building relationships with rural Albertans and growing the NDP profile in those areas.

“We think that we have a lot to offer rural Alberta and that, quite frankly, the UCP and (Kenney), in particular, have profoundly taken rural Alberta for granted,” she said. “Because of that, we think with a renewed energy amongst our membership to go out to parts of the province where we haven’t been previously as active, and talk about what they have been subjected to in the last two years, that we have huge opportunities there.”

Delegates will be asked to support a call for high-speed internet coverage across Alberta, which would remove barriers to access in rural Alberta and Indigenous communities, said the convention guidebook.

The convention comes as the NDP has a wide lead on the UCP, according to the latest polls. A Leger online survey of 1,001 Albertans conducted between March 5 to 8 found 40 per cent of respondents support the NDP, compared to just 20 per cent for the UCP.

Notley said it’s “encouraging” to see, but they aren’t taking anything for granted.

“I’ve always believed that Alberta Democrats have to work twice as hard as anybody else in the political spectrum, or the political arena,” she said. “So what we’re going to do is continue to do exactly what we have been, not only being a strong and I would argue fearless Opposition, but also trying to match every oppositional position with something that is propositional — offering Albertans a different vision, including an Alberta path to clean electricity where possible.”
