Edison too slow to respond, cities say

Calgary Winter Energy Usage Surge highlights soaring electricity demand, added megawatt-hours, and grid reliability challenges driven by extreme cold, heating loads, and climate change, with summer air conditioning also shifting seasonal peaks.

Key Points

A spike in Calgary's power use from extreme cold, adding 22k MWh and testing reliability as heating demand rises.

✅ +22,000 MWh vs Feb 2018 amid fourth-coldest February

✅ Heating loads spike; summer A/C now drives peak demand

✅ Grid reliability monitored; more solar and green resources ahead

February was so cold in Calgary that the city used enough extra energy to power 3,400 homes for a whole year, echoing record-breaking demand in B.C. in 2021 during severe cold.

Enmax Power Corporation, the primary electricity utility in the city, says the city 's energy consumption was up 22,000 megawatt hours last month compared with Februray 2018.

"We've seen through this cold period our system has held up very well. It's been very reliable," Enmax vice-president Andre van Dijk told the Calgary Eyeopener on Friday. "You know, in the absence of a windstorm combined with cold temperatures and that sort of thing, the system has actually held up pretty well."

The past month was the fourth coldest in Calgary's history, and similar conditions have pushed all-time high demand in B.C. in recent years across the West. The average temperature for last month was –18.1 C. The long-term average for February is –5.4 C.

Watching use, predicting issues

The electricity company monitors demand and load on a daily basis, always trying to predict issues before they happen, van Dijk said, and utilities have introduced winter payment plans to help customers manage bills during prolonged cold.

One of the issues they're watching is climate change, and how extreme temperatures and weather affect both the grid's reliability, as seen when Quebec shattered consumption records during cold snaps, and the public's energy use.

The colder it gets, the higher you turn up the heat. The hotter it is, the more you use air conditioning.

He also noted that using fuels then contributes to climate change, creating a cycle.

​"We are seeing variations in temperature and we've seen large weather events across the continent, across the world, in fact, that impact electrical systems, whether that's flooding, as we've experienced here, or high winds, tornadoes," van Dijk said.

"Climate change and changing weather patterns have definitely had had an impact on us as an electrical industry."

In 2012, he said, Calgary switched from using the most power during winter to using the most during summer, in large part due to air conditioning, he said.

"Temperature is a strong influencer of energy consumption and of our demand," van Dijk said.

Christmas tree lights have also become primarily LED, van Dijk said, which cuts down on a big energy draw in the winter.

He said he expects more solar and other green resources will be added into the electrical system in the future to mitigate how much the increasingly levels of energy use impact climate change, and to help moderate electricity costs in Alberta over time.

2019 Global CO2 Emissions stayed flat, IEA reports, as renewable energy growth, wind and solar deployment, nuclear output, and coal-to-gas switching in advanced economies offset increases elsewhere, supporting climate goals and clean energy transitions.

Key Points

33 gigatonnes, unchanged YoY, as advanced economies cut power emissions via renewables, gas, and nuclear.

✅ IEA reports emissions flat at 33 Gt despite 2.9% GDP growth

✅ Advanced economies cut power-sector CO2 via wind, solar, gas

✅ Nuclear restarts and mild weather aided reductions

Despite widespread expectations of another increase, global energy-related CO2 emissions stopped growing in 2019, according to International Energy Agency (IEA) data released today. After two years of growth, global emissions were unchanged at 33 gigatonnes in 2019, a notable marker in the global energy transition narrative even as the world economy expanded by 2.9%.

This was primarily due to declining emissions from electricity generation in advanced economies, thanks to the expanding role of renewable sources (mainly wind and solar across many markets), fuel switching from coal to natural gas, and higher nuclear power generation, the Paris-based organisation says in the report.

"We now need to work hard to make sure that 2019 is remembered as a definitive peak in global emissions, not just another pause in growth," said Fatih Birol, the IEA's executive director. "We have the energy technologies to do this, and we have to make use of them all."

Higher nuclear power generation in advanced economies, particularly in Japan and South Korea, avoided over 50 Mt of CO2 emissions. Other factors included milder weather in several countries, and slower economic growth in some emerging markets. In China, emissions rose but were tempered by slower economic growth and higher output from low-carbon sources of electricity. Renewables continued to expand in China, and 2019 was also the first full year of operation for seven large-scale nuclear reactors in the country.

A significant decrease in emissions in advanced economies in 2019 offset continued growth elsewhere. The USA recorded the largest emissions decline on a country basis, with a fall of 140 million tonnes, or 2.9%. US emissions are now down by almost 1 gigatonne from their peak in 2000. Emissions in the European Union fell by 160 million tonnes, or 5%, in 2019 driven by reductions in the power sector as electricity producers move away from coal in the generation mix. Japan’s emissions fell by 45 million tonnes, or around 4%, the fastest pace of decline since 2009, as output from recently restarted nuclear reactors increased.

Emissions in the rest of the world grew by close to 400 million tonnes in 2019, with almost 80% of the increase coming from countries in Asia where coal-fired power generation continued to rise, and in Australia emissions rose 2% due to electricity and transport. Coal-fired power generation in advanced economies declined by nearly 15%, reflecting a sharp fall in coal-fired electricity across multiple markets, as a result of growth in renewables, coal-to-gas switching, a rise in nuclear power and weaker electricity demand.

The IEA will publish a World Energy Outlook Special Report in June that will map out how to cut global energy-related carbon emissions by one-third by 2030 and put the world on track for longer-term climate goals, a pathway that, in Canada, will require more electricity to hit net-zero. It will also hold an IEA Clean Energy Transitions Summit in Paris on 9 July, bringing together key government ministers, CEOs, investors and other major stakeholders.

Birol will discuss the results published today tomorrow at an IEA Speaker Series event at its headquarters with energy and climate ministers from Poland, which hosted COP24 in Katowice; Spain, which hosted COP25 in Madrid; and the UK, which will host COP26 in Glasgow this year, as greenhouse gas concentrations continue to break records worldwide.

Rooftop solar grids transform urban infrastructure with distributed generation, photovoltaic panels, smart grid integration and energy storage, cutting greenhouse gas emissions, lowering utility costs, enabling net metering and community solar for low-carbon energy systems.

Key Points

Rooftop solar grids are PV systems on buildings that generate power, cut emissions, and enable smart grid integration.

✅ Lowers utility bills via net metering and demand offset

✅ Reduces greenhouse gases and urban air pollution

✅ Enables resiliency with storage, smart inverters, and microgrids

As urban areas expand and the climate crisis intensifies, cities are seeking innovative ways to integrate renewable energy sources into their infrastructure. One such solution gaining traction is the installation of rooftop solar grids. A recent CBC News article highlights the significant impact of these solar systems on urban environments, showcasing their benefits and the challenges they present.

Harnessing Unused Space for Sustainable Energy

Rooftop solar panels are revolutionizing how cities approach energy consumption and environmental sustainability. By utilizing the often-overlooked space on rooftops, these systems provide a practical solution for generating renewable energy in densely populated areas. The CBC article emphasizes that this approach not only makes efficient use of available space but also contributes to reducing a city's reliance on non-renewable energy sources.

The ability to generate clean energy directly from buildings helps decrease greenhouse gas emissions and, as scientists work to improve solar and wind power, promotes a shift towards a more sustainable energy model. Solar panels absorb sunlight and convert it into electricity, reducing the need for fossil fuels and lowering overall carbon footprints. This transition is crucial as cities grapple with rising temperatures and air pollution.

Economic and Environmental Advantages

The economic benefits of rooftop solar grids are considerable. For homeowners and businesses, installing solar panels can lead to substantial savings on electricity bills. The initial investment in solar technology is often balanced by long-term energy savings and financial incentives, such as tax credits or rebates, and evidence that solar is cheaper than grid electricity in Chinese cities further illustrates the trend toward affordability. According to the CBC report, these financial benefits make solar energy a compelling option for many urban residents and enterprises.

Environmentally, the advantages are equally compelling. Solar energy is a renewable and clean resource, and increasing the number of rooftop solar installations can play a pivotal role in meeting local and national renewable energy targets, as illustrated when New York met its solar goals early in a recent milestone. The reduction in greenhouse gas emissions from fossil fuel energy sources directly contributes to mitigating climate change and improving air quality.

Challenges in Widespread Adoption

Despite the clear benefits, the adoption of rooftop solar grids is not without its challenges. One of the primary hurdles is the upfront cost of installation. While prices for solar panels have decreased over time, the initial financial outlay remains a barrier for some property owners, and regions like Alberta have faced solar expansion challenges that highlight these constraints. Additionally, the effectiveness of solar panels can vary based on factors such as geographic location, roof orientation, and local weather patterns.

The CBC article also highlights the importance of supportive infrastructure and policies for the success of rooftop solar grids. Cities need to invest in modernizing their energy grids to accommodate the influx of solar-generated electricity, and, in the U.S., record clean energy purchases by Southeast cities have signaled growing institutional demand. Furthermore, policies and regulations must support solar adoption, including issues related to net metering, which allows solar panel owners to sell excess energy back to the grid.

Innovative Solutions and Future Prospects

The future of rooftop solar grids looks promising, thanks to ongoing technological advancements. Innovations in photovoltaic cells and energy storage solutions are expected to enhance the efficiency and affordability of solar systems. The development of smart grid technology and advanced energy management systems, including peer-to-peer energy sharing, will also play a critical role in integrating solar power into urban infrastructures.

The CBC report also mentions the rise of community solar projects as a significant development. These projects allow multiple households or businesses to share a single solar installation, making solar energy more accessible to those who may not have suitable rooftops for solar panels. This model expands the reach of solar technology and fosters greater community engagement in renewable energy initiatives.

Conclusion

Rooftop solar grids are emerging as a key element in the transition to sustainable urban energy systems. By leveraging unused rooftop space, cities can harness clean, renewable energy, reduce greenhouse gas emissions, and, as developers learn that more energy sources make better projects, achieve long-term economic savings. While there are challenges to overcome, such as initial costs and regulatory hurdles, the benefits of rooftop solar grids make them a crucial component of the future energy landscape. As technology advances and policies evolve, rooftop solar grids will play an increasingly vital role in shaping greener, more resilient urban environments.

TransLink Electric Bus Pilot launches zero-emission service in Metro Vancouver, cutting greenhouse gas emissions with fast-charging stations on Route 100, supporting renewable energy goals alongside trolley buses, CNG, and hybrid fleets.

Key Points

TransLink's Metro Vancouver program deploying charging, zero-emission buses on Route 100 to cut emissions and fuel costs.

✅ Cuts ~100 tonnes GHG and saves $40k per bus annually

✅ Five-minute on-route charging at terminals on Route 100

✅ Pilot data to guide zero-emission fleet transition by 2050

TransLink's first battery-electric buses are taking to the roads in Metro Vancouver as part of a pilot project to reduce emissions, joining other initiatives like electric school buses in B.C. that aim to cut pollution in transportation.

The first four zero-emission buses picked up commuters in Vancouver, Burnaby and  New Westminster on Wednesday. Six more are expected to be brought in, and similar launches like Edmonton's first electric bus are underway across Canada.

"With so many people taking transit in Vancouver today, electric buses will make a real difference," said Merran Smith, executive director of Clean Energy Canada, a think tank at Simon Fraser University, in a release.

According to TransLink, each bus is expected to reduce 100 tonnes of greenhouse gas emissions and save $40,000 in fuel costs per year compared to a conventional diesel bus.

"Buses already help tackle climate change by getting people out of cars, and Vancouver is ahead of the game with its electric trolleys," Smith said.

She added there is still more work to be done to get every bus off diesel, as seen with the TTC's battery-electric buses rollout in Toronto.

The buses will run along the No. 100 route connecting Vancouver and New Westminster. They recharge — it takes about five minutes — at new charging stations installed at both ends of the route while passengers load and unload or while the driver has a short break. 

Right now, more than half of TransLink's fleet currently operates with clean technology, offering insights alongside Toronto's large battery-electric fleet for other cities. 

In addition to the four new battery-electric buses, the fleet also includes hundreds of zero-emission electric trolley buses, compressed natural gas buses and hybrid diesel-electric buses, while cities like Montreal's first STM electric buses continue to expand adoption.

"Our iconic trolley buses have been running on electricity since 1948 and we're proud to integrate the first battery-electric buses to our fleet," said TransLink CEO Kevin Desmond in a press release.

TransLink has made it a goal to operate its fleet with 100 per cent renewable energy in all operations by 2050. Desmond says, the new buses are one step closer to meeting that goal.

The new battery-electric buses are part of a two-and-a-half year pilot project that looks at the performance, maintenance, and customer experience of making the switch to electric, complementing BC Hydro's vehicle-to-grid pilot initiative underway in the province.

PLREDA 2019 advances solar, wind, and geothermal on public lands, guiding DOI siting, improving transmission access, streamlining permitting, sharing revenues, and funding conservation to meet climate goals while protecting wildlife and recreation.

Key Points

A bipartisan bill to expand renewables on public lands fund conservation, speed permitting and advance U.S. climate aims.

✅ Targets 25 GW of public-land renewables by 2025

✅ Establishes wildlife conservation and recreation access funds

✅ Streamlines siting, transmission, and equitable revenue sharing

The Senate unveiled its version of a bill the House introduced in July to help the U.S. realize the extraordinary renewable energy potential of our shared public lands.

Senator Martha McSally (R-AZ) and a bipartisan coalition of western Senators introduced a Senate version of draft legislation that will help the Department of the Interior tap the renewable energy potential of our shared public lands. The western Senators represent Arizona, New Mexico, Colorado, Montana, and Idaho.

Elsewhere in the West, lawmakers have moved to modernize Oregon hydropower to streamline licensing, signaling broad regional momentum.

The Public Land Renewable Energy Development Act of 2019 (PLREDA) facilitates siting of solar, wind, and geothermal energy projects on public lands, boosts funding for conservation, and promotes ambitious renewable energy targets that will help the U.S. take action on the climate crisis.

Like the House version, the Senate bill enjoys strong bi-partisan support and industry endorsement. The Senate version makes few notable changes to the bill introduced in July by Representatives Mike Levin (D-CA) and Paul Gosar (R-AZ). It includes:

• A commitment to enhance natural resource conservation and stewardship via the establishment of a fish and wildlife conservation fund that would support conservation and restoration work and other important stewardship activities.
• An ambitious renewable energy production goal for the Department of the Interior to permit a total of 25 gigawatts of renewable energy on public lands by 2025—nearly double the current generating capacity of projects currently on our public lands.
• Establishment of criteria for identifying appropriate areas for renewable energy development using the 2012 Western Solar Plan as a model. Key criteria to be considered include access to transmission lines and likelihood of avoiding or minimizing conflict with wildlife habitat, cultural resources, and other resources and values.
• Improved public access to Federal lands for recreational uses via funds made available for preserving and improving access, including enhancing public access to places that are currently inaccessible or restricted.
• Sharing of revenues raised from renewable energy development on public lands in an equitable manner that benefits local communities near new renewable energy projects and supports the efficient administration of permitting requirements.
• Creating incentives for renewable energy development by giving Interior the authority to reduce rental rates and capacity fees to ensure new renewable energy development remains competitive in the marketplace.

NRDC strongly supports this legislation, and we will do our utmost to facilitate its passage into law. There is no question that in our era of runaway climate change, legislation that balances energy production with environmental conservation and stewardship of our public lands is critical.

PLREDA takes a balanced approach to using our public lands to help lead the U.S. toward a low-carbon future, as states pursue 100% renewable electricity goals nationwide. The bill outlines a commonsense approach for federal agencies to play a meaningful role in combatting climate change.

UK Coal-Free Electricity Record highlights rapid growth in renewables as National Grid phases out coal; wind, solar, and offshore projects surge, green tariffs expand, and energy comparison helps consumers switch to cheaper, cleaner deals.

Key Points

Britain's longest coal-free run, enabled by renewables, lower demand, and grid shifts for cheaper, greener tariffs.

✅ Record set after two months without coal-fired generation

✅ Renewables outpace fossil fuels; wind and solar dominate

✅ Green tariffs expand; prices at three-year lows

On Wednesday 10 June, Britain hit a significant landmark: the UK went for two full months without burning coal to generate power – that's the longest period since the 1880s, following earlier milestones such as a full week without coal power in the recent past.

According to the National Grid, Britain has now run its electricity network without burning coal since midnight on the 9 April. This coal-free period has beaten the country’s previous record of 18 days, six hours and 10 minutes, which was set in June 2019, even though low-carbon generation stalled in 2019 according to analyses.

With such a shift in Britain’s drive for renewables and lower electricity demand following the coronavirus lockdown, as Britain recorded its cleanest electricity during lockdown to date, now may be the perfect time to do an online energy comparison and switch to a cheaper, greener deal.

Only a decade ago, around 40 per cent of Britain’s electricity came from coal generation, but since then the country has gradually shifted towards renewable energy, with the coal share at record lows in the system today. When Britain was forced into lockdown in response to the coronavirus pandemic, electricity demand dropped sharply, and the National Grid took the four remaining coal-fired plants off the network.

Over the past 10 years, Britain has invested heavily in renewable energy. Back in 2010, only 3 per cent of the country's electricity came from wind and solar, and many people remained sceptical. However, now, the UK has the biggest offshore wind industry in the world. Plus, last year, construction of the world’s single largest wind farm was completed off the coast of Yorkshire.

At the same time, Drax – Britain’s biggest power plant – has started to switch from burning coal to burning compressed wooden pellets instead, reflecting the UK's progress as it keeps breaking its coal-free energy record again across the grid. By this time next year, the plant hopes to have phased out coal entirely.

So far this year, renewables have generated more power than all fossil fuels put together, the BBC reports, and the energy dashboard shows the current mix in real time. Renewables have been responsible for 37 per cent of electricity supplied to the network, with wind and solar surpassing nuclear for the first time, while fossil fuels have accounted for 35 per cent. During the same period, nuclear accounted for 18 per cent and imports made up the remaining 10 per cent.

What does this mean for consumers?

As the country’s electricity supply moves more towards renewables, customers have more choice than ever before. Most of the ‘Big Six’ energy companies now have tariffs that offer 100 per cent green electricity. On top of this, specialist green energy suppliers such as Bulb, Octopus and Green Energy UK make it easier than ever to find a green energy tariff.

The good news is that our energy comparison research suggests that green energy doesn’t have to cost you more than a traditional fixed-price energy contract would. In fact, some of the cheapest energy suppliers are actually green companies.

At present, energy bills are at three-year lows, which means that now is the perfect time to switch supplier. As prices remain low and renewables begin to dominate the marketplace, more switchers will be drawn to green energy deals than ever before.

However, if you’re interested in choosing a green energy supplier, make sure that you look at the company's fuel mix. This way, you’ll be able to see whether they are guaranteeing the usage of green energy, or whether they’re just offsetting your usage. All suppliers must report how their energy is generated to Ofgem, so you’ll easily be able to compare providers.

You may find that you pay more for a supplier that generates its own energy from renewables, or pay less if the supplier simply matches your usage by buying green energy. You can decide which option is right for you after comparing the prices.
