Renewable Energy Security strengthens affordability and grid reliability through electrification, wind, and solar, reducing fossil fuel volatility exposed by the Ukraine crisis, aligning with IEA guidance and the Paris Agreement to deliver resilient, low-cost power.

Key Points

Renewable energy security is reliable, affordable power from electrification, wind and solar, cutting fossil fuel risk.

✅ Wind and solar now outcompete gas for new power capacity.

✅ Diversifies supply and reduces fossil price volatility.

✅ Requires grid flexibility, storage, and demand response.

Oil, gas, and coal have been the central pillar of the global energy system throughout the 20th century. And for decades, these fossil fuels have been closely associated with energy security.  

The perception of energy security, however, is rapidly changing. Renewables form an increasing share of energy sectors worldwide as countries look to deliver on the Paris Agreement and mitigate the effects of climate change, with IEA clean energy investment now significantly outpacing fossil fuels. Moreover, Russia’s invasion of Ukraine has demonstrated how relying on fossil fuels for power, heating, and transport has left many countries vulnerable or energy insecure.  

The International Energy Agency (IEA) defines energy security as “the uninterrupted availability of energy sources at an affordable price” (IEA, 2019a). This definition hardly describes today’s global energy situation, with the cancellation of natural gas deliveries and skyrocketing prices for oil and gas products, and with supply chain challenges in clean energy that also require attention. These circumstances have cascading effects on electricity prices in countries like the United Kingdom that rely heavily on natural gas to produce electricity. In Europe, energy insecurity has been even further amplified since the Russian corporation Gazprom recently cut off gas supplies to several countries.  

As a result, energy security has gained new urgency in Canada and worldwide, creating opportunities in the global electricity market for Canada. Recent events provide a stark reminder of the volatility and potential vulnerability of global fossil fuel markets and supply chains. Even in Canada, as one of the largest producers of oil and gas in the world, the price of fuels depends on global and regional market forces rather than government policy or market design. Thus, the average monthly price for gasoline in Canada hit a record high of CAD 2.07 per litre in May 2022 (Figure 1), and natural gas prices surged to a record CAD 7.54 per MMBtu in May 2022 (Figure 2).  

Energy price increases of this magnitude are more than enough to strain Canadian household budgets. But on top of that, oil and gas prices have accelerated inflation more broadly as it has become more expensive to produce, transport, and store goods, including food and other basic commodities (Global News, 2022).  

Renewable Energy Is More Affordable 

In contrast to oil and gas, renewable energy can reliably deliver affordable energy, as shown by falling wholesale electricity prices in markets with growing clean power. This is a unique and positive aspect of today’s energy crisis compared to historical crises: options for electrification and renewable-based electricity systems are both available and cost-effective.  

For new power capacity, wind and solar are now cheaper than any other source, and wind power is making gains as a competitive source in Canada. According to Equinor (2022), wind and solar were already cheaper than gas-based power in 2020. This means that renewable energy was already the cheaper option for new power before the recent natural gas price spikes. As illustrated in Figure 3, the cost of new renewable energy has dropped so dramatically that, for many countries, it is cheaper to install new solar or wind infrastructure than to keep operating existing fossil fuel-based power plants (International Renewable Energy Agency, 2021). This means that replacing fossil-based electricity generation with renewables would save money and reduce emissions. Wind and solar prices are expected to continue their downward trends as more countries increase deployment and learn how to best integrate these sources into the grid. 

Renewable Energy Is Reliable 

To deliver on the uninterrupted availability side of the energy security equation, renewable power must remain reliable even as more variable energy sources, like wind and solar, are added to the system, and regional leaders such as the Prairie provinces will help anchor this transition. For Canada and other countries to achieve high energy security through electrification, grid system operations must be able to support this, and pathways to zero-emissions electricity by 2035 are feasible.

Renewable Electricity Generation is accelerating the shift from fossil fuels, as wind, solar, and hydro boost the electric power sector, lowering emissions and overtaking nuclear while displacing coal and natural gas in the U.S. grid.

Key Points

Renewable electricity generation is power from non-fossil sources like wind, solar, and hydro to cut emissions.

✅ Driven by wind, solar, and hydro adoption

✅ Reduces fossil fuel dependence and emissions

✅ Increasing share in the electric power sector

The transition to electric vehicles is largely driven by a need to reduce our reliance on fossil fuels and reduce emissions associated with burning fossil fuels, while declining US electricity use also shapes demand trends in the power sector. In 2021, 40% of the electricity produced by the electric power sector was derived from non-fossil fuel sources.

Since 2007, the increase in non-fossil fuel sources has been largely driven by “Other Renewables” which is predominantly wind and solar. This has resulted in renewables (including hydroelectric) overtaking nuclear power’s share of electricity generation in 2021 for the first time since 1984. An increasing share of electricity generation from renewables has also led to a declining share of electricity from fossil fuel sources like coal, natural gas, and petroleum, with renewables poised to eclipse coal globally as deployment accelerates.

Includes net generation of electricity from the electric power sector only, and monthly totals can fluctuate, as seen when January power generation jumped on a year-over-year basis.

Net generation of electricity is gross generation less the electrical energy consumed at the generating station(s) for station service or auxiliaries, and the projected mix of sources is sensitive to policies and natural gas prices over time. Electricity for pumping at pumped-storage plants is considered electricity for station service and is deducted from gross generation.

“Natural Gas” includes blast furnace gas and other manufactured and waste gases derived from fossil fuels, while in the UK wind generation exceeded coal for the first time in 2016.

“Other Renewables” includes wood, waste, geo-thermal, solar and wind resources among others.

“Other” category includes batteries, chemicals, hydrogen, pitch, purchased steam, sulfur, miscellaneous technologies, and, beginning in 2001, non-renewable waste (municipal solid waste from non-biogenic sources, and tire-derived fuels), noting that trends vary by country, with UK low-carbon generation stalling in 2019.

Texas After-Labor Day School Start could ease ERCOT's power grid strain by shifting peak demand, lowering air-conditioning loads in schools, improving grid reliability, reducing electricity costs, and curbing emissions during extreme heat the summer months.

Key Points

A proposed calendar shift to start school after Labor Day to lower ERCOT peak demand, costs, and grid risk.

✅ Cuts school HVAC loads during peak summer heat

✅ Lowers costly peaker plant use and electricity rates

✅ Requires calendar changes, testing and activities shifts

As Texas faces increasing demands on its power grid, a new proposal is gaining traction: starting the school year after Labor Day. This idea, reported by the Dallas News, suggests that delaying the start of the academic year could help alleviate some of the pressure on the state’s electricity grid during the peak summer months, potentially leading to both grid stability and financial savings. Here’s an in-depth look at how this proposed change could impact Texas’s energy landscape and education system.

The Context of Power Grid Strain

Texas's power grid, operated by the Electric Reliability Council of Texas (ERCOT), has faced significant challenges in recent years. Extreme weather events, record-breaking temperatures, and high energy demand have strained the grid, and some analyses argue that climate change, not demand is the biggest challenge today, leading to concerns about reliability and stability. The summer months are particularly taxing, as the demand for air conditioning surges, often pushing the grid to its limits.

In this context, the idea of adjusting the school calendar to start after Labor Day has been proposed as a potential strategy to help manage electricity demand. By delaying the start of school, proponents argue that it could reduce the load on the power grid during peak usage periods, thereby easing some of the stress on energy resources.

Potential Benefits for the Power Grid

The concept of delaying the school year is rooted in the potential benefits for the power grid. During the hottest months of summer, the demand for electricity often spikes as families use air conditioning to stay cool, and utilities warn to prepare for blackouts as summer takes hold. School buildings, typically large and energy-intensive facilities, contribute significantly to this demand when they are in operation.

Starting school later could help reduce this peak demand, as schools would be closed during the hottest months when the grid is under the most pressure. This reduction in demand could help prevent grid overloads and reduce the risk of power outages, at a time when longer, more frequent outages are afflicting the U.S. power grid, ultimately contributing to a more stable and reliable electricity supply.

Additionally, a decrease in peak demand could help lower electricity costs. Power plants, particularly those that are less efficient and more expensive to operate, are often brought online during periods of high demand. By reducing the peak load, the state could potentially minimize the need for these costly power sources, leading to lower overall energy costs.

Financial and Environmental Considerations

The financial implications of starting school after Labor Day extend beyond just the power grid. By reducing energy consumption during peak periods, the state could see significant savings on electricity costs. This, in turn, could lead to lower utility bills for schools, businesses, and residents alike, a meaningful relief as millions risk electricity shut-offs during summer heat.

Moreover, reducing the demand for electricity from fossil fuel sources can have positive environmental impacts. Lower peak demand may reduce the reliance on less environmentally friendly energy sources, and aligns with calls to invest in a smarter electricity infrastructure nationwide, thereby decreasing greenhouse gas emissions and contributing to overall environmental sustainability.

Challenges and Trade-offs

While the proposal offers potential benefits, it also comes with challenges and trade-offs. Adjusting the school calendar would require significant changes to the academic schedule, potentially affecting extracurricular activities, summer programs, and family plans, and comparisons to California's reliability challenges underscore the complexity. Additionally, there could be resistance from various stakeholders, including parents, educators, and students, who are accustomed to the current school calendar.

There are also logistical considerations to address, such as how a delayed start might impact standardized testing schedules and the academic calendar for higher education institutions. These factors would need to be carefully evaluated to ensure that the proposed changes do not adversely affect educational outcomes or create unintended consequences.

Looking Ahead

The idea of starting Texas schools after Labor Day represents an innovative approach to addressing the challenges facing the state’s power grid. By potentially reducing peak demand and lowering energy costs, and alongside efforts to connect Texas's grid to the rest of the nation, this proposal could contribute to greater grid stability and financial savings. However, careful consideration and planning will be essential to navigate the complexities of altering the school calendar and to ensure that the benefits outweigh the challenges.

As Texas continues to explore solutions for managing its power grid and energy resources, the proposal to shift the school year schedule provides an intriguing possibility. It reflects a broader trend of seeking creative and multifaceted approaches to balancing energy demand, environmental sustainability, and public needs.

In conclusion, starting schools after Labor Day could offer tangible benefits for Texas’s power grid and financial well-being. As discussions on this proposal advance, it will be important to weigh all factors and engage stakeholders to ensure a successful and equitable implementation.

Attosecond Electron Transport uses ultrafast lasers and single-cycle light pulses to drive tunneling in bowtie gold nanoantennas, enabling sub-femtosecond switching in optoelectronic nanostructures and surpassing picosecond silicon limits for next-gen computing.

Key Points

A light-driven method that manipulates electrons with ultrafast pulses to switch currents within attoseconds.

✅ Uses single-cycle light pulses to drive electron tunneling

✅ Achieves 600 attosecond current switching in nano-gaps

✅ Enables optoelectronic, plasmonic devices beyond silicon

When it comes to data transfer and computing, the faster we can shift electrons and conduct electricity the better – and scientists have just been able to transport electrons at sub-femtosecond speeds (less than one quadrillionth of a second) in an experimental setup.

The trick is manipulating the electrons with light waves that are specially crafted and produced by an ultrafast laser. It might be a long while before this sort of setup makes it into your laptop, but similar precision is seen in noninvasive interventions where targeted electrical stimulation can boost short-term memory for limited periods, and the fact they pulled it off promises a significant step forward in terms of what we can expect from our devices.

Right now, the fastest electronic components can be switched on or off in picoseconds (trillionths of a second), a pace that intersects with debates over 5G electricity use as systems scale, around 1,000 times slower than a femtosecond.

With their new method, the physicists were able to switch electric currents at around 600 attoseconds (one femtosecond is 1,000 attoseconds).

"This may well be the distant future of electronics," says physicist Alfred Leitenstorfer from the University of Konstanz in Germany. "Our experiments with single-cycle light pulses have taken us well into the attosecond range of electron transport."

Leitenstorfer and his colleagues were able to build a precise setup at the Centre for Applied Photonics in Konstanz. Their machinery included both the ability to carefully manipulate ultrashort light pulses, and to construct the necessary nanostructures, including graphene architectures, where appropriate.

The laser used by the team was able to push out one hundred million single-cycle light pulses every single second in order to generate a measurable current. Using nanoscale gold antennae in a bowtie shape (see the image above), the electric field of the pulse was concentrated down into a gap measuring just six nanometres wide (six thousand-millionths of a metre).

As a result of their specialist setup and the electron tunnelling and accelerating it produced, the researchers could switch electric currents at well under a femtosecond – less than half an oscillation period of the electric field of the light pulses.

Getting beyond the restrictions of conventional silicon semiconductor technology has proved a challenge for scientists, but using the insanely fast oscillations of light to help electrons pick up speed could provide new avenues for pushing the limits on electronics, as our power infrastructure is increasingly digitized and integrated with photonics.

And that's something that could be very advantageous in the next generation of computers: scientists are currently experimenting with the way that light and electronics could work together in all sorts of different ways, from noninvasive brain stimulation to novel sensors.

Eventually, Leitenstorfer and his team think that the limitations of today's computing systems could be overcome using plasmonic nanoparticles and optoelectronic devices, using the characteristics of light pulses to manipulate electrons at super-small scales, with related work even exploring electricity from snowfall under specific conditions.

"This is very basic research we are talking about here and may take decades to implement," says Leitenstorfer.

The next step is to experiment with a variety of different setups using the same principle. This approach might even offer insights into quantum computing, the researchers say, although there's a lot more work to get through yet - we can't wait to see what they'll achieve next.

Baltimore Substation Attack Plot highlights alleged neo-Nazi plans targeting electrical substations and the power grid, as FBI and DHS warn of domestic extremism threats to critical infrastructure, with arrests in Maryland disrupting potential sniper attacks.

Key Points

An alleged extremist plot to disable Baltimore's power grid by shooting substations, thwarted by federal arrests.

✅ Two suspects charged in Maryland conspiracy

✅ Targets included five substations around Baltimore

✅ FBI cites domestic extremism threat to infrastructure

A neo-Nazi in Florida and a Maryland woman conspired to attack several electrical substations in the Baltimore area, federal officials say.

Sarah Beth Clendaniel and Brandon Clint Russell were arrested and charged in a conspiracy to disable the power grid by shooting out substations via "sniper attacks," according to a criminal complaint from the U.S. Attorney's Office for the District of Maryland.

Clendaniel allegedly said she wanted to "completely destroy this whole city" and was planning to target five substations situated in a "ring" around Baltimore, the complaint said. Russell is part of a violent extremist group that has cells in multiple states, and he previously planned to attack critical infrastructure in Florida, the complaint said.

"This planned attack threatened lives and would have left thousands of Marylanders in the cold and dark," Maryland U.S. Attorney Erek Barron said in a press release. "We are united and committed to using every legal means necessary to disrupt violence, including hate-fueled attacks."

The news comes as concerns grow about an increase in targeted substation attacks on U.S. substations tied to domestic extremism.

What to know about substation attacks

Federal data shows vandalism and suspicious activities at electrical facilities soared nationwide last year, and cyber actors have accessed utilities' control rooms as well.

At the end of the year, attacks or potential attacks were reported on more than a dozen substations and one power plant across five states, and Symantec documented Russia-linked Dragonfly activity targeting the energy sector earlier. Several involved firearms.

In December, targeted attacks on substations in North Carolina left tens of thousands without power amid freezing temperatures, spurring renewed focus on protecting the U.S. power grid among officials. The FBI is investigating.

Vandalism at facilities in Washington left more than 21,000 without electricity on Christmas Day, even as hackers breached power-plant systems in other states. Two men were arrested, and one told police he planned to disrupt power to commit a burglary.

The Department of Homeland Security last year said domestic extremists had been developing "credible, specific plans" since at least 2020 and would continue to "encourage physical attacks against electrical infrastructure," and the U.S. government has condemned Russia for power grid hacking as well.

Last February, three neo-Nazis pleaded guilty to federal crimes related to a scheme to attack the grid with rifles, with each targeting a substation in a different region of the U.S., even as reports that Russians hacked into US electric utilities drew widespread attention.
