Toronto is poised to become the first city in North America to make green roofs mandatory on most new buildings and set standards for their construction.

A city committee considered a proposed bylaw that would require roofs on new buildings with an area of 5,000 square metres or greater to be 30% to 60% covered by vegetation. The bigger the building, the more planted space it would have to have — otherwise fines of up to $100,000 could be levied.

As drafted, the bylaw would cover mid-to high-rise condos, retail space and office towers, but exempt low-rise, large-scale industrial, nonprofit housing and public buildings such as schools.

But even as Toronto's powerful development industry was urging the city to slow down and keep green roofs strictly voluntary, local politicians were complaining the draft bylaw was too cautious for a metropolis vying to be the most environmentally minded on the continent.

Deputy Mayor Joe Pantalone, who helped bring the city's first power-generating windmill to the Exhibition grounds, said he was "disappointed" the first draft of the bylaw was so "tepid."

Mr. Pantalone asked city staff to come back in a month with a proposal that would include schools, low-rise buildings on "Main Street" and even private residences.

"Either we are the leading city in the world or we're the ones who looked in the mirror and got scared," he said.

BILD — the Toronto and GTA Building Industry and Land Development Association — was quick to urge city politicians to reconsider.

The association sent a letter to the city's chief planner expressing reservations and proposing a pilot project first instead of a full-scale bylaw.

"We have significant concerns with the city's proposal to require and govern the construction of green roofs. We continue to advocate that green roofs be implemented on a voluntary basis," it stated.

"If the home-building and development industry are provided with various incentives, this approach would assist the city with its objectives, while not forcing green roofs on those who may choose to use other forms of sustainable development for their projects."

Since his election in 2003, Toronto's hybrid-driving Mayor David Miller has put the environment front-and-centre on the municipal agenda, setting up a LiveGreen office to promote eco-friendly living, offering rebates for low-flush toilets, banning bottled water sales at city hall, taking on the coffee industry over the disposable cup and studying climate change within civic boundaries.

A new city report touts the environmental benefits of rooftops covered largely in plants and organic material as opposed to asphalt or metal.

These include "reducing the urban heat island effect and energy consumption, improving air quality and storm water management and creating opportunities for biodiversity and habitat creation and beautification of the city."

Steve Daniels, who sat on a green roof technical advisory committee representing BILD, said developers are interested in working with the city to create more green roofs. But he said they can add "hundreds of thousands of dollars... if not more" to the cost of a project.

"The range can be anywhere on the lower end from $18 a square foot to around $28 a square foot. It's somewhere in that range that we're looking at for an added cost," Mr. Daniels said.

"It's always a concern. Compounded with development charges, compounded with application fees that go up, it's a cumulative effect. So this is just another added cost that has to be factored in at the end of the day."

On top of that, he said there is trepidation about how the new bylaw, which derives its authority from the City of Toronto Act, would mesh with the Ontario Building Code and other city zoning requirements, such as those that call for outdoor amenities for high-rise condos. Those amenities often end up on the rooftop.

Stephen Upton, vice-president development planning at building giant Tridel, pointed out that once installed, the rooftop shrubbery has to be left untouched for two years to allow it to take root.

More information is also required about the longevity of green roofs and how much should be budgeted in a condo corporation's building fund for future replacement.

"I think there's still quite a bit left to be understood, digested and refined," Mr. Upton said. "Toronto green standards, those are things that shouldn't be mandated but should be encouraged."

But while the developers were balking at the bylaw, environmental groups were urging Toronto to move further and faster.

Steven Peck, president of the 10-year-old Toronto-based group Green Roofs for Healthy Cities, said the city's efforts could create jobs and be on the "leading edge" of the technology.

"We're very concerned that there's been a watering down of the requirements and we're concerned it will set a negative precedent for cities elsewhere in North America," Mr. Peck said, adding Toronto is "perched on the edge of really starting to get serious about implementing green roofs."

The issue will return to the planning and growth committee for further debate on May 6.

IEA: Asia set to use half of world's electricity by 2025

Asia Electricity Consumption 2025 highlights an IEA forecast of surging global power demand led by China, lagging access in Africa, rising renewables and nuclear output, stable emissions, and weather-dependent grids needing flexibility and electrification.

 

Key Points

An IEA forecast that Asia will use half of global power by 2025, led by China, as renewables and nuclear drive supply.

✅ Asia to use half of global electricity; China leads growth

✅ Africa just 3% consumption despite rapid population growth

✅ Renewables, nuclear expand; grids must boost flexibility

 

Asia will for the first time use half of the world’s electricity by 2025, even as global power demand keeps rising and Africa continues to consume far less than its share of the global population, according to a new forecast released Wednesday by the International Energy Agency.

Much of Asia’s electricity use will be in China, a nation of 1.4 billion people whose China's electricity sector is seeing shifts as its share of global consumption will rise from a quarter in 2015 to a third by the middle of this decade, the Paris-based body said.

“China will be consuming more electricity than the European Union, United States and India combined,” said Keisuke Sadamori, the IEA’s director of energy markets and security.

By contrast, Africa — home to almost a fifth of world’s nearly 8 billion inhabitants — will account for just 3% of global electricity consumption in 2025.

“This and the rapidly growing population mean there is still a massive need for increased electrification in Africa,” said Sadamori.

The IEA’s annual report predicts that low-emissions sources will account for much of the growth in global electricity supply over the coming three years, including nuclear power and renewables such as wind and solar. This will prevent a significant rise in greenhouse gas emissions from the power sector, it said.

Scientists say sharp cuts in all sources of emissions are needed as soon as possible to keep average global temperatures from rising 1.5 degrees Celsius (2.7 Fahrenheit) above pre-industrial levels. That target, laid down in the 2015 Paris climate accord, appears increasingly doubtful as temperatures have already increased by more than 1.1 C since the reference period.

One hope for meeting the goal is a wholesale shift away from fossil fuels such as coal, gas and oil toward low-carbon sources of energy. But while some regions are reducing their use of coal and gas for electricity production, in others, soaring electricity and coal use are increasing, the IEA said.

The 134-page also report warned that surging electricity demand and supply are becoming increasingly weather dependent, a problem it urged policymakers to address.

“In addition to drought in Europe, there were heat waves in India (last year),” said Sadamori. “Similarly, central and eastern China were hit by heatwaves and drought. The United States, where electricity sales projections continue to fall, also saw severe winter storms in December, and all those events put massive strain on the power systems of these regions.”

“As the clean energy transition gathers pace, the impact of weather events on electricity demand will intensify due to the increased electrification of heating, while the share of weather-dependent renewables poised to eclipse coal will continue to grow in the generation mix,” the IEA said. “In such a world, increasing the flexibility of power systems while ensuring security of supply and resilience of networks will be crucial.”

Lawmakers question FERC licensing process for dams in West Virginia

FERC Hydropower Licensing Dispute centers on FERC authority, Clean Water Act compliance, state water quality certifications, Federal Power Act timelines, and Army Corps dams on West Virginia's Monongahela River licenses.

 

Key Points

An inquiry into FERC's licensing process and state water quality authority for hydropower at Monongahela River dams.

✅ Questions on omitted state water quality conditions

✅ Debate over starting Clean Water Act certification timelines

✅ Potential impacts on states' rights and licensing schedules

 

As federal lawmakers, including Democrats pressing FERC, plan to consider a bill that would expand Federal Energy Regulatory Commission (FERC) licensing authority, questions emerged on Tuesday about the process used by FERC to issue two hydropower licenses for existing dams in West Virginia.

In a letter to FERC Chairman Neil Chatterjee, Democratic leaders of the House Energy and Commerce Committee, as electricity pricing changes were being debated, raised questions about hydropower licenses issued for two dams operated by the U.S. Army Corps of Engineers on the Monongahela River in West Virginia.

U.S. Reps. Frank Pallone Jr. (D-NJ), the ranking member of the Subcommittee on Energy, Bobby Rush (D-IL), the ranking member of the Subcommittee on Environment, and John Sarbanes (D-MD), amid Maryland clean energy enforcement concerns, questioned why FERC did not incorporate all conditions outlined in a West Virginia Department of Environmental Protection water quality certificate into plans for the projects.

“By denying the state its allotted time to review this application and submit requirements on these licenses, FERC is undermining the state’s authority under the Clean Water Act and Federal Power Act to impose conditions that will ensure water quality standards are met,” the letter stated.

The House of Representatives was slated to consider the Hydropower Policy Modernization Act of 2017, H.R. 3043, later in the week. The measure would expand FERC authority over licensing processes, a theme mirrored in Maine's transmission line debate over interstate energy projects. Opponents of the bill argue that the changes would make it more difficult for states to protect their clean water interests.

West Virginia has announced plans to challenge FERC hydropower licenses for the dams on the Monongahela River, echoing Northern Pass opposition seen in New Hampshire.

Charting a path to net zero electricity emissions by the middle of the century

Clean Energy Standard charts a federal path to decarbonize the power sector, scaling renewables, wind, solar, nuclear, and carbon capture to slash emissions, create green jobs, and reach net-zero targets amid the climate crisis.

 

Key Points

A federal policy to expand clean power and cut emissions with renewables, nuclear, and carbon capture toward net-zero.

✅ Mandates annual increases in clean electricity supply

✅ Includes renewables, nuclear, hydro, and carbon capture

✅ Targets rapid emissions cuts and net-zero by mid-century

 

The world has been put on notice. Last year, both the UN Intergovernmental Panel on Climate Change and the U.S. National Climate Assessment warned that we need to slash greenhouse gas emissions to avoid disastrous impacts of global warming. Their direct language forecasting devastating effects on our health, economics, environment, and ways of life has made even more urgent the responsibility we all have to act boldly to combat the climate crisis.

This week, we’re adding one important tool for addressing the climate crisis to the national conversation.

Together, we’re taking that bold action. The Climate reports made clear that to limit the global temperature rise and stave off devastating impacts to our climate—human-caused CO2 emissions must fall rapidly by 2030 and that we, as a global community, underscored at the Katowice climate talks, must reach net-zero emissions by the middle of the century. The Clean Energy Standard is federal legislation that offers a pathway toward decarbonizing our power sector and helping our nation accomplish a goal of net-zero emissions by the 2050s.

Under this plan, any company selling retail electricity will have a mandate to increase the amount of clean energy provided to its customers. It will incentivize clean electricity investment to put the U.S. on a sustainable path.

To deal most effectively with a crisis, all tools must be on the table. Our plan focuses solely on emissions, and there is a place for all technologies that can put us on the path to net zero. That will mean drastic increases in wind and solar energy for sure, as states like California pursue a 100% carbon-free electricity mandate to accelerate deployment, but nuclear power, hydro power, and fossil fuels with carbon capture and storage all have important roles to play.

We’re doing this because the science is clear – tackling our climate crisis requires serious and rapid action to control greenhouse gas emissions, and the push for decarbonization is irreversible according to many. Inaction on the climate crisis puts our families at risk, and we’re not wasting any time. This is also an opportunity to create good-paying green jobs that can last generations and uplift the middle class.

We are doing this for the environment, but also for jobs and economic competitiveness. The green economy is the future and we’re ready to see it grow, with states like New York advancing a Green New Deal that drives innovation. The United States can lead, or we can follow, and we want our nation to lead.

And, because as a New Mexican and a Minnesotan, we know that the impacts of climate change go far beyond the headlines and political discourse. It means devastation within tamarack forests and an increase in deadly fires. It means hotter summers and shorter winters with extreme temperature swings throughout the year. It means devastating flash floods with increasingly intense rain. It’s impacting our pocketbooks when farmers and small businesses who work the land in rural communities are unable to make ends meet.

States across the country are already acting to combat the climate crisis – including Minnesota's 2050 carbon-free electricity plan and New Mexico. But in order to truly address climate change, we have to be in this together as Americans. If the problem is far-reaching, our solutions must be equally as holistic.

It's why we've worked with green groups and activists, unions, and communities across the country - from urban to rural - to create a solution that understands the different starting points communities face in reaching net zero emissions, but doesn't shrink from the absolute need to reach that standard.

There is not one solution to climate change – it will take a collective group of individuals prepared to boldly act. And we are ready to take on that fight.

In Congress, we have formed the House Select Committee on the Climate Crisis and the Senate Democrats’ Special Committee on the Climate Crisis to hear from everyday Americans how climate change is affecting them – and how we can come together to find solutions that build on the historic climate deal passed this year. We have heard the stories of young people worried about their futures. And we realize there is a sense of urgency to act.

Over the coming weeks and months, we will be building support from communities across the country to make this plan a reality. We will continue working with stakeholders to ensure every voice is heard. Most importantly, we will continue listening to you and your communities.

Sierra Club: Governor Abbott's Demands Would Leave Texas More Polluted and Texans in the Dark

Texas Energy Policy Debate centers on ERCOT and PUC directives, fossil fuels vs renewables, grid reliability, energy efficiency, battery storage, and blackout risks, shaping Texas power market rules, conservation alerts, and capacity planning.

 

Key Points

Policy fight over ERCOT/PUC rules weighing fossil fuels vs renewables and storage to bolster Texas grid reliability.

✅ ERCOT and PUC directives under political scrutiny

✅ Fossil fuel subsidies vs renewable incentives and storage

✅ Focus on grid reliability, efficiency, and blackout prevention

 

Earlier this week, Governor Abbott released a letter to the Public Utility Commission of Texas (PUC) and the Electric Reliability Council of Texas (ERCOT), demanding electricity market reforms that Abbott falsely claims will "increase power generation capacity and to ensure the reliability of the Texas power grid."

Unfortunately, Abbott's letter promotes polluting, unreliable fossil fuels, attacks safer clean energy options, and ignores solutions that would actually benefit everyday Texans.

"Governor Abbott, in a blatant effort to politicize Texans' energy security, wants to double down on fossil fuels, even though they were the single largest point of failure during both February's blackouts and June's energy conservation alerts," said Cyrus Reed, Interim Director & Conservation Director of the Lone Star Chapter of the Sierra Club.

"Many of these so-called solutions were considered and rejected most recently by the Texas Legislature. Texas must focus on expanding clean and reliable renewable energy, energy efficiency, and storage capacity, as voters consider funding to modernize generation in the months ahead.

"We can little afford to repeat the same mistakes that have failed to provide enough electricity where it is needed most and cost Texans billions of dollars. Instead of advocating for evidence-based solutions, Abbott wants to be a culture warrior for coal and gas, even as he touts grid readiness amid election season, even when it results in blackouts across Texas."

Ontario tables legislation to lower electricity rates

Ontario Clean Energy Adjustment lowers hydro bills by shifting global adjustment costs, cutting time-of-use rates, and using OPG debt financing; ratepayers get inflation-capped increases for four years, then repay costs over 20 years.

 

Key Points

A 20-year line item repaying debt used to lower rates for 10 years by shifting global adjustment costs off hydro bills.

✅ 17% average bill cut takes effect after royal assent

✅ OPG-managed entity assumes debt for 10 years

✅ 20-year surcharge repays up to $28B plus interest

 

Ontarians will see lowered hydro bills for the next 10 years, but will then pay higher costs for the following 20 years, under new legislation tabled Thursday.

Ten weeks after announcing its plan to lower hydro bills, the Liberal government introduced legislation to lower time-of-use rates, take the cost of low-income and rural support programs off bills, and introduce new social programs.

It will lower time-of-use rates by removing from bills a portion of the global adjustment, a charge consumers pay for above-market rates to power producers. For the next 10 years, a new entity overseen by Ontario Power Generation will take on debt to pay that difference.

Then, the cost of paying back that debt with interest -- which the government says will be up to $28 billion -- will go back onto ratepayers' bills for the next 20 years as a "Clean Energy Adjustment."

An average 17-per-cent cut to bills will take effect 15 days after the hydro legislation receives royal assent, even as a Nov. 1 rate increase was set by the Ontario Energy Board, but there are just eight sitting days left before the Ontario legislature breaks for the summer. Energy Minister Glenn Thibeault insisted that leaves the opposition "plenty" of time for review and debate.

Premier Kathleen Wynne promised to cut hydro bills and later defended a 25% rate cut after widespread anger over rising costs helped send her approval ratings to record lows.

Electricity bills in the province have roughly doubled in the last decade, due in part to green energy initiatives, and Thibeault said the goal of this plan is to better spread out those costs.

"Like the mortgage on your house, this regime will cost more as we refinance over a longer period of time, but this is a more equitable and fair approach when we consider the lifespan of the clean energy investments, and generating stations across our province," he said.

NDP critic Peter Tabuns called it a "get-through-the-election" next June plan.

"We're going to take on a huge debt so Kathleen Wynne can look good on the hustings in the next few months and for decades we're going to pay for it," he said.

The legislation also holds rate increases to inflation for the next four years. After that, they'll rise more quickly, as illustrated by a leaked cabinet document the Progressive Conservatives unveiled Thursday.

The Liberals dismissed the document as containing outdated projections, but confirmed that it went before cabinet at some point before the government decided to go ahead with the hydro plan.

From about 2027 onward -- when consumers would start paying off the debt associated with the hydro plan -- Ontario electricity consumers will be paying about 12 per cent more than they would without the Liberal government's plan to cut costs in the short term, even though a deal with Quebec was not expected to reduce hydro bills, the government document projected.

But that was just one of many projections, said Energy Minister Glenn Thibeault.

"We have been working on this plan for months, and as we worked on it the documents and calculations evolved," he said.

The government's long-term energy plan is set to be updated this spring, and Thibeault said it will provide a more accurate look at how the hydro plan will reduce rates, even as a recovery rate could lead to higher hydro bills in certain circumstances.

Progressive Conservative critic Todd Smith said the "Clean Energy Adjustment" is nothing more than a revamped debt retirement charge, which was on bills from 2002 to 2016 to pay down debt left over from the old Ontario Hydro, the province's giant electrical utility that was split into multiple agencies in 1999 under the previous Conservative government.

"The minister can call it whatever he wants but it's right there in the graph, that there is going to be a new charge on the line," Smith said. "It's the debt retirement charge on steroids."

Minnesota Power energizes Great Northern Transmission Line

Great Northern Transmission Line delivers 250 MW of carbon-free hydropower from Manitoba Hydro, strengthening Midwest grid reliability, enabling wind storage balancing, and advancing Minnesota Power's EnergyForward strategy for cleaner, renewable energy across the region.

 

Key Points

A 500 kV cross-border line delivering 250 MW of carbon-free hydropower, strengthening reliability and enabling renewables.

✅ 500 kV, 224-mile line from Manitoba to Minnesota

✅ Delivers 250 MW hydropower via ALLETE-Minnesota Power

✅ Enables wind storage and grid balancing with Manitoba Hydro

 

Minnesota Power, a utility division of ALLETE Inc. (NYSE:ALE), has energized its Great Northern Transmission Line, bringing online an innovative delivery and storage system for renewable energy that spans two states and one Canadian province, similar to the Maritime Link project in Atlantic Canada.

The 500 kV line is now delivering 250 megawatts of carbon-free hydropower from Manitoba, Canada, to Minnesota Power customers.

Minnesota Power completed the Great Northern Transmission Line (GNTL) in February 2020, ahead of schedule and under budget. The 224-mile line runs from the Canadian border in Roseau County to a substation near Grand Rapids, Minnesota. It consists of 800 tower structures which were fabricated in the United States and used 10,000 tons of North American steel. About 2,200 miles of wire were required to install the line's conductors. The GNTL also is contributing significant property tax revenue to local communities along the route.

"This is such an incredible achievement for Minnesota Power, ALLETE, and our region, and is the culmination of a decade-long vision brought to life by our talented and dedicated employees," said ALLETE President and CEO Bethany Owen. "The GNTL will help Minnesota Power to provide our customers with 50 percent renewable energy less than a year from now. As part of our EnergyForward strategy, it also strengthens the grid across the Midwest and in Canada, enhancing reliability for all of our customers."

With the GNTL energized and connected to Manitoba Hydro's recently completed Manitoba-Minnesota Transmission Project at the border, the companies now have a unique "wind storage" mechanism that quickly balances energy supply and demand in Minnesota and Manitoba, and enables a larger role for renewables in the North American energy grid.

The GNTL and its delivery of carbon-free hydropower are important components of Minnesota Power's EnergyForward strategy to transition away from coal and add renewable power sources while maintaining reliable and affordable service for customers, echoing interties like the Maritime Link that facilitate regional power flows. It also is part of a broader ALLETE strategy to advance and invest in critical regional transmission and distribution infrastructure, such as the TransWest Express transmission project, to ensure grid integrity and enable cleaner energy to reduce carbon emissions.

"The seed for this renewable energy initiative was planted in 2008 when Minnesota Power proposed purchasing 250 megawatts of hydropower from Manitoba Hydro. Beyond the transmission line, it also included a creative asset swap to move wind power from North Dakota to Minnesota, innovative power purchase agreements, and a remarkable advocacy process to find an acceptable route for the GNTL," said ALLETE Executive Chairman Al Hodnik. "It marries wind and water in a unique connection that will help transform the energy landscape of North America and reduce carbon emissions related to the existential threat of climate change."

Minnesota Power and Manitoba Hydro, a provincial Crown Corporation, coordinated on the project from the beginning, navigating National Energy Board reviews along the way. It is based on the companies' shared values of integrity, environmental stewardship and community engagement.

"The completion of Minnesota Power's Great Northern Transmission Line and our Manitoba-Minnesota Transmission Project is a testament to the creativity, perseverance, cooperation and skills of hundreds of people over so many years on both sides of the border," said Jay Grewal, president and CEO of Manitoba Hydro. "Perhaps even more importantly, it is a testament to the wonderful, longstanding relationship between our two companies and two countries. It shows just how much we can accomplish when we all work together toward a common goal."

Minnesota Power engaged federal, state and local agencies; the sovereign Red Lake Nation and other tribes, reflecting First Nations involvement in major transmission planning; and landowners along the proposed routes beginning in 2012. Through 75 voluntary meetings and other outreach forums, a preferred route was selected with strong support from stakeholders that was approved by the Minnesota Public Utilities Commission in April 2016.

A four-year state and federal regulatory process culminated in late 2016 when the federal Department of Energy approved a Presidential Permit for the GNTL, similar to the New England Clean Power Link process, needed because of the international border crossing. Construction of the line began in early 2017.

"A robust stakeholder process is essential to the success of any project, but especially when building a project of this scope," Owen said. "We appreciated the early engagement and support from stakeholders, local communities and tribes, agencies and regulators through the many approval milestones to the completion of the GNTL."
