Homes and office buildings consume three-quarters of U.S. electricity, and the National Renewable Energy Laboratory wants to lower that figure by erecting what it believes will be the largest "net-zero" energy building in the world — one that produces as much power onsite as it uses.

The Department of Energy, which runs the Golden-based lab nestled in the foothills west of Denver, and its contractors hope the $64 million structure will provide a national blueprint for making buildings greener and cutting energy use.

"Our hope is that it really starts to change the direction of society and the way we think of buildings," said Byron Haselden, president of Haselden Construction, the general contractor.

Achieving a zero-energy, "green" building is driving the 220,000-square-foot complex's design and construction.

"What typically happens is when a building gets designed, the architects design something and the engineers figure out how to build it, how to heat it and how to cool it," said Eric Telesmanich, project manager of NREL's infrastructure and development office.

In this case, engineers steered the design. Stantec Consulting started by studying what materials to use and how to orient the building. What emerged is a big "H" shaped structure with the two prongs on the west end closer to each other than on the east end. That configuration provides the best daylight and cuts the amount of electricity needed for lighting.

The connecting structure is the lobby, which will feature paneling made from pine trees killed by the bark beetle infestation in Colorado's central mountains. The wood also is used to fuel a heating plant on the campus.

Other features include natural ventilation, large windows to let in light and evaporative cooling. For comfort, no employee will be farther than 30 feet from windows, which are 6 feet wide and 7 to 9 feet long. The windows have a combination of glass and coatings to let in light while keeping unwanted heat out.

Transpired solar collectors — metal sheets with strategically cut holes designed by NREL — will pull air heated by the sun into the building on cold days.

In the basement, a labyrinth of concrete walls will capture the day's heat or the night's cool air to be slowly released upstairs. Engineers wrote a computer program to determine the labyrinth's size and shape and calculate air flow.

Exterior walls feature an insulated precast concrete panel system. Water will flow through piping in the floors to warm or cool the air. Recycled materials include reclaimed natural gas pipes as the columns to support the floors and walls.

And the building will let people know when it's a good day to open the windows or leave them closed, based on temperatures and historical climate information.

"There will be a little icon on your computer," Macey said. "It will tell occupants how the building is doing over the course of the year."

Once completed in June, the building will provide offices for 740 NREL employees. It's expected to use one-half to one-third the power of a similar-sized office structure.

The project's architects, engineers and contractors have an exacting client. NREL evaluates private-sector buildings for energy efficiency and is starting to track zero-energy buildings.

"It allows us to demonstrate what we can do with our technologies," said Jeffrey Baker, director of the office of laboratory operations at the DOE field office in Golden. "That's what this project is all about. This is walking the walk and shouting the talk."

NREL is documenting all work and will make that information public. Contractors working on the project insist that following NREL's example won't be too costly or cumbersome for the private sector, considering savings in energy costs over the life of the structure.

The roughly $280 per square foot construction cost is in line with comparable office buildings, said Philip Macey of RNL Design Inc., the project's designers.

"NREL and the design team should be commended for the vision and effort to go far beyond the minimum standards that many buildings are built to," said Gordon Holness, president of the American Society of Heating, Refrigerating and Air-Conditioning Engineers.

Holness' group sets many of the U.S. standards and guidelines to make construction more energy efficient and environmentally friendly.

The Department of Energy wants the complex to exceed by 50 percent the standard for energy efficiency used as a basis for building codes nationwide. Another goal is to earn the top rating — platinum — by the U.S. Green Building Council's Leadership in Energy and Environmental Design.

Christmas electricity spike equivalent to roasting 1.5 million turkeys: BC Hydro

BC Hydro Holiday Energy Saving Tips highlight electricity usage trends and power conservation during Christmas cooking. Use efficient appliances, lower the thermostat, and track consumption with MyHydro to reduce bills while hosting guests.

 

Key Points

Guidelines from BC Hydro to cut holiday electricity usage via efficient cooking, smart thermostats, and MyHydro tracking.

✅ Use microwave, toaster oven, or slow cooker to save power.

✅ Batch-bake cookies and pies to minimize oven cycles.

✅ Set thermostat to 18 C and monitor use with MyHydro.

 

BC Hydro is reminding British Columbians to conserve power over the holidays after a report commissioned by the utility found the arrival of guests for Christmas dinner results in a 15% increase in electricity usage, and it expects holiday usage to rise as gatherings ramp up.

Cooking appears to be the number one culprit for the uptick in peoples’ hydro bills. According to BC Hydro press release, British Columbians use about 8,000 megawatt hours more of electricity by mid-day Christmas — that's about 1.5 million turkeys roasted in electric ovens — while Ontario electricity demand shifted as people stayed home during the pandemic.
 article continues below 

About 95% of British Columbians said they would make meals at home from scratch over the holiday season, mirroring the uptick in residential electricity use observed during the pandemic. The survey found that inviting friends or family over trumped any plans people had to buy pre-made meals or order take-out. Six in 10 respondents said they would also rather bake holiday treats than pick them up pre-made from the store. 

The survey also showed people in B.C. are taking steps to reduce their electricity usage, echoing earlier findings that many British Columbians changed daily electricity habits during the pandemic. When participants were asked whether they were conscious of how much electricity they used when visiting friends or family, 80% said they would be taking steps to limit their usage.


And while cooking meals from scratch over the holidays may contribute to a spike in a person's electricity bill, some studies have found that, when comparing their overall environmental impact against that of ready-made meals, a roasted dinner has a lower negative impact.

Still, there are many ways to improve your energy efficiency and save some money over the holiday season, and conserving can also help the grid during events like the recent atypical storm response noted by BC Hydro. BC Hydro recommends:

• using smaller appliances whenever possible, such as a microwave, crockpot or toaster oven as they use less than half the power of a regular electric oven;

• baking cookies or pies in batches to save energy;

• turning down the household thermostat to 18 C when possible to reduce costs during peak hydro rates where applicable;

• and tracking how much electricity you use through the MyHydro tool alongside potential time-of-use rates for smarter scheduling

Alberta breaks summer electricity record, still far short of capacity

Alberta Electricity Peak Demand surged to 10,638 MW, as AESO reported record summer load from air conditioning, Stampede visitors, and heatwave conditions, with ample generation capacity, stable grid reliability, and conservation urged during 5-7 p.m.

 

Key Points

It is the record summer power load in Alberta, reaching 10,638 MW, with evening conservation urged by AESO.

✅ Record 10,638 MW at 4 pm; likely to rise this week

✅ Drivers: A/C use, heat, Stampede visitors

✅ AESO reports ample capacity; conserve 5-7 pm

 

Consumer use hit 10,638 MW, blowing past a previous high of 10,520 MW set on July 9, 2015, said the Alberta Electric System Operator (AESO).

“We hit a new summer peak and it’s likely we’ll hit higher peaks as the week progresses,” said AESO spokeswoman Tara De Weerd.

“We continue to have ample supply, and as Alberta's electricity future trends toward more wind, our generators are very confident there aren’t any issues.”

That new peak was set at 4 p.m. but De Weerd said it was likely to be exceeded later in the day.

Heightened air conditioner use is normally a major driver of such peak electricity consumption, said De Weerd.

She also said Calgary’s big annual bash is also likely playing a role.

“It’s the beginning of Stampede, you have an influx of visitors so you’ll have more people using electricity,” she said.

Alberta’s generation capacity is 16,420 MW, said the AESO, with wind power increasingly outpacing coal in the province today.

There are no plans, she said, for any of the province’s electricity generators to shut down any of their plants for maintenance or other purposes in the near future as demand rises.

The summer peak is considerably smaller than that reached in the depths of Alberta’s winter.

Alberta’s winter peak usage was recorded last year and was 11,458 MW.

Though the province’s capacity isn’t being strained by the summer heat, De Weerd still encouraged consumers to go easy during the peak use time of the day, between 5 and 7 p.m.

“We don’t have to be running all of our appliances at once,” she said.

Alberta exports an insignificant amount of electricity to Montana, B.C. and Saskatchewan, where demand recently set a new record.

The weather forecast calls for temperatures to soar above 30C through the weekend.

In northern Canada, Yukon electricity demand recently hit a record high, underscoring how extreme temperatures can strain systems.

Modular nuclear reactors a 'long shot' worth studying, says Yukon gov't

Yukon SMR Feasibility Study examines small modular reactors as low-emissions nuclear power for Yukon's grid and remote communities, comparing costs, safety, waste, and reliability with diesel generation, renewables, and energy efficiency.

 

Key Points

An official assessment of small modular reactors as low-emission power options for Yukon's grid and remote sites.

✅ Compares SMR costs vs diesel, hydro, wind, and solar

✅ Evaluates safety, waste, fuel logistics, decommissioning

✅ Considers remote community loads and grid integration

 

The Yukon government is looking for ways to reduce the territory's emissions, and wondering if nuclear power is one way to go.

The territory is undertaking a feasibility study, and, as some developers note, combining multiple energy sources can make better projects, to determine whether there's a future for SMRs — small modular reactors — as a low-emissions alternative to things such as diesel power.

The idea, said John Streicker, Yukon's minister of energy, mines and resources, is to bring the SMRs into the Yukon to generate electricity.

"Even the micro ones, you could consider in our remote communities or wherever you've got a point load of energy demand," Streicker said. "Especially electricity demand."

For remote coastal communities elsewhere in Canada, tidal energy is being explored as a low-emissions option as well.

SMRs are nuclear reactors that use fission to produce energy, similar to existing large reactors, but with a smaller power capacity. The International Atomic Energy Agency (IAEA) defines reactors as "small" if their output is under 300 MW. A traditional nuclear power plant produces about three times as much power or more.

They're "modular" because they're designed to be factory-assembled, and then installed where needed. 

Several provinces have already signed an agreement supporting the development of SMRs, and in Alberta's energy mix that conversation spans both green and fossil power, and Canada's first grid-scale SMRs could be in place in Ontario by 2028 and Saskatchewan by 2032.

A year ago, the government of Yukon endorsed Canada's SMR action plan, at a time when analysts argue that zero-emission electricity by 2035 is practical and profitable, agreeing to "monitor the progress of SMR technologies throughout Canada with the goal of identifying potential for applicability in our northern jurisdiction."

The territory is now following through by hiring someone to look at whether SMRs could make sense as a cleaner-energy alternative in Yukon. 

The territorial government has set a goal of reducing emissions by 45 per cent by 2030, excluding mining emissions, even as some analyses argue that zero-emissions electricity by 2035 is possible, and "future emissions actions for post-2030 have not yet been identified," reads the government's request for proposals to do the SMR study. 

Streicker acknowledges the potential for nuclear power in Yukon is a bit of "long shot" — but says it's one that can't be ignored.

"We need to look at all possible solutions," he said, as countries such as New Zealand's electricity sector debate their future pathways.

"I don't want to give the sense like we're putting all of our emphasis and energy towards nuclear power. We're not."

According to Streicker, it's nothing more than a study at this point.

Don't bother, researcher says
Still, M.V. Ramana, a professor at the School of Public Policy and Global Affairs at the University of British Columbia, said it's a study that's likely a waste of time and money. He says there's been plenty of research already, and to him, SMRs are just not a realistic option for Yukon or anywhere in Canada.

"I would say that, you know, that study can be done in two weeks by a graduate student, essentially, all right? They just have to go look at the literature on SMRs and look at the critical literature on this," Ramana said.

Ramana co-authored a research paper last year, looking at the potential for SMRs in remote communities or mine sites. The conclusion was that SMRs will be too expensive and there won't be enough demand to justify investing in them.

He said nuclear reactors are expensive, which is why their construction has "dried up" in much of the world.

"They generate electricity at very high prices," he said.

'They just have to go look at the literature,' said M.V. Ramana, a professor at the School of Public Policy and Global Affairs at the University of British Columbia. (Paul Joseph)
"[For] smaller reactors, the overall costs go down. But the amount of electricity that they will generate goes down even further."

The environmental case is also shaky, according to a statement signed last year by dozens of Canadian environmental and community groups, including the Sierra Club, Greenpeace, the Council of Canadians and the Canadian Environmental Law Associaton (CELA). The statement calls SMRs a "dirty, dangerous distraction" from tackling climate change and criticized the federal government for investing in the technology.

"We have to remember that the majority of the rhetoric we hear is from nuclear advocates. And so they are promoting what I would call, and other legal scholars and academics have called, a nuclear fantasy," said Kerrie Blaise of CELA.

Blaise describes the nuclear industry as facing an unknown future, with some of North America's larger reactors set to be decommissioned in the coming years. SMRs are therefore touted as the future.

"They're looking for a solution. And so that I would say climate change presents that timely solution for them."

Blaise argues the same safety and environmental questions exist for SMRs as for any nuclear reactors — such as how to produce and transport fuel safely, what to do with waste, and how to decommission them — and those can't be glossed over in a single-minded pursuit of lower carbon emissions.  

Main focus is still renewables, minister says
Yukon's energy minister agrees, and he's eager to emphasize that the territory is not committed to anything right now beyond a study.

"Every government has a responsibility to do diligence around this," Streicker said.

He also dismisses the idea that studying nuclear power is any sort of distraction from his government's response to climate change right now. Yukon's main focus is still renewable energy such as solar and wind power, though Canada's solar progress is often criticized as lagging, increasing efficiency, and connecting Yukon's grid to the hydro project in Atlin, B.C., he said.

Streicker has been open to nuclear energy in the past. As a federal Green Party candidate in 2008, Streicker broke with the party line to suggest that nuclear could be a viable energy alternative. 

He acknowledges that nuclear power is always a hot-button issue, and Yukoners will have strong feelings about it. A lot will depend on how any future regulatory process works, he says.

"There's some people that think it's the 'Hail Mary,' and some people that think it's evil incarnate," he said. 

"Buried deep within Our Clean Future [Yukon's climate change strategy], there's a line in there that says we should keep an eye on other technologies, for example, nuclear. That's what this [study] is — it's to keep an eye on it."

Minister approves 30-megawatt wind farm expansion in Eastern Kings

Eastern Kings Wind Farm Expansion advances P.E.I. renewable energy with seven new wind turbines, environmental assessment, wildlife monitoring of birds and bats, and community consultation to double output to 30 MW for domestic consumption.

 

Key Points

A P.E.I. project adding seven turbines for 30 MW, under 17 conditions, with wildlife monitoring and community oversight.

✅ Seven new turbines, larger than existing units

✅ 17 conditions, monthly compliance reporting

✅ Two-year wildlife study for birds and bats

 

A proposal to expand an existing wind farm in eastern P.E.I. has been given the go-ahead, according to P.E.I.’s Department of Environment, Water and Climate Change, as related grid work like a new transmission line progresses in the region.

Minister Natalie Jameson approved the P.E.I. Energy Corporation’s Eastern Kings Wind Farm expansion project, the province announced in a release Wednesday afternoon, as Atlantic Canada advances other renewable initiatives like tidal power to diversify supply.

The project will be subject to 17 conditions, which were drawn from a review of the 80 responses the province received from the public on the proposed Eastern Kings Wind Farm expansion.

The corporation must provide a summary on the status of each condition to the department on a monthly basis.

“This decision balances the needs of people, communities, wellness and the environment,” Jameson said in the release.

“It allows this renewable energy project to proceed and reduce greenhouse [gas] emissions that cause climate change while mitigating the project’s impact to the Island’s ecosystem.”

The P.E.I. Energy Corporation wants to double the output of its Eastern Kings Wind Farm with the installation of seven wind turbines between the communities of Elmira and East Point to develop 30 megawatts of wind power for domestic consumption, according to the minister’s impact assessment, aligning with regional moves to expand wind and solar projects across Atlantic Canada.

The new turbines are expected to be larger than the existing 10 at the site, even as regional utilities study major grid changes to integrate more renewables.

Project must comply with conditions

In February, the province said it would identify any specific questions or concerns it felt needed to be addressed in the submissions, according to Greg Wilson, manager of environmental land management for the province, while some advocate for independent electricity planning to guide such decisions.

Public feedback closed in January, after an earlier extension to wait for a supplemental report on birds and bats.

The corporation needs to comply with all conditions – such as monitoring environmental impact, setting up an environmental management plan and creating a committee to address concerns – listed in the release on Wednesday, amid calls from environmental advocates to reduce biomass use in electricity generation.

A condition in the release suggests representatives from L’nuey, the Souris and Area Wildlife Branch, the Rural Municipality of Eastern Kings and local residents to make up the committee.

The corporation will also need to conduct a study over two years after construction to look at the impact on bats and birds, and implement a protocol to report deaths of birds to federal and provincial authorities.

According to Canada Energy Regulator, roughly 98 per cent of power generated on P.E.I. comes from wind farms. It also said there were 203 megawatts installed on P.E.I. as of 2018, and the majority of energy consumed on the Island comes from New Brunswick from a mix of nuclear, fossil fuels and hydroelectricity, while in Nova Scotia, the utility has increased biomass generation as part of its supply mix.

Ex-SpaceX engineers in race to build first commercial electric speedboat

Arc One Electric Speedboat delivers zero-emission performance, quiet operation, and reduced maintenance, leveraging battery propulsion, aerospace engineering, and venture-backed innovation to cut noise pollution, fuel costs, and water contamination in high-performance marine recreation.

 

Key Points

Arc One Electric Speedboat is a battery-powered, zero-emission craft offering quiet, high-performance marine cruising.

✅ 475 hp, 24 ft hull, about 40 mph top speed

✅ Cuts noise, fumes, and water contamination vs gas boats

✅ Backed by Andreessen Horowitz; ex-SpaceX engineers

 

A team of former SpaceX rocket engineers have joined the race to build the first commercial electric speedboat.

The Arc Boat company announced it had raised $4.25m (£3m) in seed funding to start work on a 24ft 475-horsepower craft that will cost about $300,000.

The LA-based company, which is backed by venture capital firm Andreessen Horowitz (an early backer of Facebook and Airbnb), said the first model of the Arc One boat would be available for sale by the end of the year.

Mitch Lee, Arc’s chief executive, said he wanted to build electric boats because of the impact conventional petrol- or diesel-powered boats have on the environment.

“They not only get just two miles to the gallon, they also pump a lot of those fumes into the water,” Lee said. “In addition, there is the huge noise pollution factor [of conventional boats] and that is awful for the marine life. With gas-powered boats it’s not just carbon emissions into the air, it’s also polluting the water and causing noise pollution. Electric boats, like electric ships clearing the air on the B.C. coast, eliminate all that.”

Lee said electric vessels would also reduce the hassle of boat ownership. “I love being out on the water, being on a boat is so much fun, but owning a boat is so awful,” he said. “I have always believed that electric boats make sense. They will be quicker, quieter and way cheaper and easier to operate and maintain, with access options like an electric boat club in Seattle lowering barriers for newcomers.”

While the first models will be very expensive, Lee said the cost was mostly in developing the technology and cheaper versions would be available in the future, mirroring advances in electric aviation seen across the industry. “It is very much the Tesla approach – we are starting up market and using that income to finance research and development and work our way down market,” he said.

Lee said the technology could be applied to larger craft, and even ferries could run on electricity in the future, as projects for battery-electric high-speed ferries begin to scale.

“We started in February with no team, no money and no warehouse,” he said. “By December we are going to be selling the Arc One, and we are hiring aggressively because we want to accelerate the adoption of electric boats across a whole range of craft, including an electric-ready ferry on Kootenay Lake.”

Lee founded the company with fellow mechanical engineer Ryan Cook. Cook, the company’s chief technology officer, was previously the lead mechanical engineer at Elon Musk’s space exploration company SpaceX where he worked on the Falcon 9 rocket, the world’s first orbital class reusable rocket. In parallel, Harbour Air's electric aircraft highlights cross-sector electrification. Apart from Lee, all of Arc’s employees have some experience working at SpaceX.

The Arc boat, which would have a top speed of 40 mph, joins a number of startups rushing to make the first large-scale production of electric-powered speedboats, while a Vancouver seaplane airline demonstrates complementary progress with a prototype electric aircraft. The Monaco Yacht Club this month held a competition for electric boat prototypes to “instigate a new vision and promote all positive approaches to bring yachting into line” with global carbon dioxide emission reduction targets. Sweden’s Candela C-7 hydrofoil boat was crowned the fastest electric vessel.

RBC agrees to buy electricity from new southern Alberta solar power farm project

RBC Renewable Energy PPA supports a 39 MW Alberta solar project, with Bullfrog Power and BluEarth Renewables, advancing clean energy in a deregulated market through a long-term power purchase agreement in Canada today.

 

Key Points

A long-term power purchase agreement where RBC buys most output from a 39 MW Alberta solar project via Bullfrog Power.

✅ 39 MW solar build in County of Forty Mile, Alberta

✅ Majority of output purchased by RBC via Bullfrog Power

✅ Supports cost-competitive renewables in deregulated market

 

The Royal Bank of Canada says it is the first Canadian bank to sign a long-term renewable energy power purchase agreement, a deal that will support the development of a 39-megawatt, $70-million solar project in southern Alberta, within an energy powerhouse province.

The bank has agreed with green energy retailer Bullfrog Power to buy the majority of the electricity produced by the project, as a recent federal green electricity contract highlights growing demand, to be designed and built by BluEarth Renewables of Calgary.

The project is to provide enough power for over 6,400 homes and the panel installations will cover 120 hectares, amid a provincial renewable energy surge that could create thousands of jobs, the size of 170 soccer fields.

The solar installation is to be built in the County of Forty Mile, a hot spot for renewable power that was also chosen by Suncor Energy Inc. for its $300-million 200-MW wind power project (approved last year and then put on hold during the COVID-19 pandemic), and home to another planned wind power farm in Alberta.

BluEarth says commercial operations at its Burdett and Yellow Lake Solar Project are expected to start up in April 2021, underscoring solar power growth in the province.

It says the agreement shows that renewable energy can be cost-competitive, with lower-cost solar contracts in a deregulated electricity market like Alberta’s, adding the province has some of the best solar and wind resources in Canada.

“We’re proud to be the first Canadian bank to sign a long-term renewable energy power purchase agreement, demonstrating our commitment to clean, sustainable power, as Alberta explores selling renewable energy at scale,” said Scott Foster, senior vice-president and global head of corporate real estate at RBC.
