Renewable growth drives common goals for electricity networks across the globe

Iraq Electricity Crisis intensifies as summer heat drives demand; households face power outages, reliance on private generators, distorted tariffs, and strained grid capacity despite government reforms, Siemens upgrades, and IEA warnings.

Key Points

A supply-demand gap causing outages, generator reliance, and grid inefficiencies across Iraq, worsened by summer peaks.

✅ Siemens deal to upgrade generation and grid

✅ Progressive tariffs to curb demand and waste

✅ Private generators fill gaps but raise costs

At a demonstration in June 2018, protesters in Basra loaded a black box resembling a coffin with the inscription “Electricity” onto the roof of a car. This was one demonstration of how much of a political issue electricity is in Iraq.

With what is likely to be another hot summer ahead, there is increasing pressure on the Baghdad government to improve access to electricity and water.

Many Iraqis blame the government for not providing adequate services despite the country’s oil wealth. Protests in southern Iraq last year turned violent, with demonstrators attacking governmental and political parties’ buildings; in neighboring Iran, blackouts also sparked protests over outages.

“It is very hard” to deal with the electricity issues, said Iraqi journalist Methaq al-Fayyadh, adding that the lack of reliable electricity was not a new problem and affects most parts of the country.

Dozens of people protested June 1 in Karbala against prices for new generators and demanded an improvement to the electricity situation.

In anticipation of high temperatures during Eid al-Fitr, the Electricity Ministry called on governorates to adhere to allocated quotas and told the public to ration electricity.

“Outages remain a daily occurrence for most households because increasing generating capacity has been outrun by increasing demand for electricity, as surging demand worldwide demonstrates,” noted the International Energy Agency (IAE) in April.

This is particularly the case, the authors said, as the hot summer months, when temperatures can top 50 degrees Celsius, drive up the use of air conditioning.

The Iraqi government has made improving the electricity supply one of its priorities, including nuclear power plans under consideration. The Electricity Ministry, headed by Luay al-Khatteeb, announced in May that national electricity production had reached 17 gigawatts.

Khatteeb presented comparative electricity data for May from 2018 and 2019, indicating production increases on every day of the month. IEA data indicate that available electricity supply has increased over the past five years and the gap between supply and demand has widened.

The government signed an agreement with German company Siemens this year to upgrade Iraq’s electricity grid, and in parallel deals with Iran to rehabilitate and develop the grid were finalized, according to Iranian officials. The agreement “includes the addition of new and highly efficient power generation capacity, rehabilitation and upgrade of existing plants and the expansion of transmission and distribution networks,” Siemens said.

The Iraqi prime minister’s office said the 4-year plan would be worth $15.7 billion. The first phase includes the installation of 13 transformer stations, cooling systems for power stations and building a 500-megawatt, gas-fired power plant south of Baghdad.

In an interview with Al-Monitor, Khatteeb said radical changes would happen in 2020, stating that the current situation was not “ideal” but “better” because of steps taken to create more energy, amid discussions on energy cooperation with Iran that could shape implementation.

Robert Tollast, of the Iraq Energy Institute, said the economics of the electricity system is distorted. Subsidies ensured that electricity provided by the national grid is almost free, he said. However, while the subsidies were designed to help the poor, the tariff system disadvantages them and does not create incentives to consume electricity more efficiently, he said.

A large part of families’ electricity expenditures goes to operators of privately owned generators, which run on fuel. These neighbourhood generators are used to close gaps in the electricity supply but are expensive, and regional fuel arrangements such as ENOC’s swap of Iraqi fuel have highlighted supply constraints. Generator operators have sometimes worked with armed groups to prevent upgrades to the grid that could hurt their business.

Until 1990, the Iraq electricity sector was considered among the best in the region. That legacy was destroyed by successive wars and international sanctions. With Iraq’s population growing at a rate of 1 million per year, peak demand is projected to double by 2030 if left unchecked, the IEA estimated.

Tollast said efforts to improve the distribution system and increase capacity are key but it is important “to tackle the problem from the demand side.” This entails implementing a progressive tariff scheme so users pay more if they consume more, he said. There is a “tremendous use of energy per capita in Iraq,” Tollast said.

In the current tariff structure, consumers pay a fixed price if they use more than 4,000-kilowatt hours per year, a relatively low amount, meaning the price per unit drops the more one consumes.

Any change to the tariff system must be accompanied by a “political campaign” to explain the changes, said Tollast, adding that more investment in the electricity sector and a “change in culture” of using electricity was needed. “The current system is unsustainable, even with high oil prices,” he said.

Fayyadh said people don’t expect the government will be able to fix the electricity issue before summer, having failed to do so in the past.

Tollast struck a more optimistic tone, saying it was unlikely that Iran, which supplies about 40% of Iraq’s power, would cut its export of electricity to Iraq this year as it did in 2018. He added that the water situation was better than last year when the country experienced drought. Iraq has also been processing more flare gas, which can be used to generate electricity.

“There is an expectation that this year might not be as bad as last year,” he concluded.

Air-gen Protein Nanowire Generator delivers clean energy by harvesting ambient humidity via Geobacter-derived conductive nanowires, generating continuous hydrovoltaic electricity through moisture gradients, electrodes, and proton diffusion for sustainable, low-waste power in diverse climates.

Key Points

A device using Geobacter protein nanowires to harvest humidity, producing continuous DC power via proton diffusion.

✅ 7 micrometer film between electrodes adsorbs water vapor.

✅ Output: ~0.5 V, 17 uA/cm2; stack units to scale power.

✅ Geobacter optimized via engineered E. coli for mass nanowires.

They found it buried in the muddy shores of the Potomac River more than three decades ago: a strange "sediment organism" that could do things nobody had ever seen before in bacteria.

This unusual microbe, belonging to the Geobacter genus, was first noted for its ability to produce magnetite in the absence of oxygen, but with time scientists found it could make other things too, like bacterial nanowires that conduct electricity.

For years, researchers have been trying to figure out ways to usefully exploit that natural gift, and they might have just hit pay-dirt with a device they're calling the Air-gen. According to the team, their device can create electricity out of… well, almost nothing, similar to power from falling snow reported elsewhere.

"We are literally making electricity out of thin air," says electrical engineer Jun Yao from the University of Massachusetts Amherst. "The Air-gen generates clean energy 24/7."

The claim may sound like an overstatement, but a new study by Yao and his team describes how the air-powered generator can indeed create electricity with nothing but the presence of air around it. It's all thanks to the electrically conductive protein nanowires produced by Geobacter (G. sulfurreducens, in this instance).

The Air-gen consists of a thin film of the protein nanowires measuring just 7 micrometres thick, positioned between two electrodes, referencing advances in near light-speed conduction in materials science, but also exposed to the air.

Because of that exposure, the nanowire film is able to adsorb water vapour that exists in the atmosphere, offering a contrast to legacy hydropower models, enabling the device to generate a continuous electrical current conducted between the two electrodes.

The team says the charge is likely created by a moisture gradient that creates a diffusion of protons in the nanowire material.

"This charge diffusion is expected to induce a counterbalancing electrical field or potential analogous to the resting membrane potential in biological systems," the authors explain in their study.

"A maintained moisture gradient, which is fundamentally different to anything seen in previous systems, explains the continuous voltage output from our nanowire device."

The discovery was made almost by accident, when Yao noticed devices he was experimenting with were conducting electricity seemingly all by themselves.

"I saw that when the nanowires were contacted with electrodes in a specific way the devices generated a current," Yao says.

"I found that exposure to atmospheric humidity was essential and that protein nanowires adsorbed water, producing a voltage gradient across the device."

Previous research has demonstrated hydrovoltaic power generation using other kinds of nanomaterials – such as graphene-based systems now under study – but those attempts have largely produced only short bursts of electricity, lasting perhaps only seconds.

By contrast, the Air-gen produces a sustained voltage of around 0.5 volts, with a current density of about 17 microamperes per square centimetre, and complementary fuel cell solutions can help keep batteries energized, with a current density of about 17 microamperes per square centimetre. That's not much energy, but the team says that connecting multiple devices could generate enough power to charge small devices like smartphones and other personal electronics – concepts akin to virtual power plants that aggregate distributed resources – all with no waste, and using nothing but ambient humidity (even in regions as dry as the Sahara Desert).

"The ultimate goal is to make large-scale systems," Yao says, explaining that future efforts could use the technology to power homes via nanowire incorporated into wall paint, supported by energy storage for microgrids to balance supply and demand.

"Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production."

If there is a hold-up to realising this seemingly incredible potential, it's the limited amount of nanowire G. sulfurreducens produces.

Related research by one of the team – microbiologist Derek Lovley, who first identified Geobacter microbes back in the 1980s – could have a fix for that: genetically engineering other bugs, like E. coli, to perform the same trick in massive supplies.

"We turned E. coli into a protein nanowire factory," Lovley says.

"With this new scalable process, protein nanowire supply will no longer be a bottleneck to developing these applications."

Minnesota Carbon-Free Power by 2050 aims to shift utilities to renewable energy, wind and solar, boosting efficiency while managing grid reliability, emissions, and costs under a clean energy mandate and statewide climate policy.

Key Points

A statewide goal to deliver 100% carbon-free power by 2050, prioritizing renewables, efficiency, and grid reliability.

✅ Targets 100% carbon-free electricity statewide by 2050

✅ Prioritizes wind, solar, and efficiency before fossil fuels

✅ Faces utility cost, reliability, and legislative challenges

Gov. Tim Walz's plan for Minnesota to get 100 percent of its electricity from carbon-free sources by 2050, similar to California's 100% carbon-free mandate in scope, was criticized Tuesday at its first legislative hearing, with representatives from some of the state's smaller utilities saying they can't meet that goal.

Commerce Commissioner Steve Kelley told the House climate committee that the Democratic governor's plan is ambitious. But he said the state's generating system is "aging and at a critical juncture," with plants that produce 70 percent of the state's electricity coming up for potential retirement over the next two decades. He said it will ensure that utilities replace them with wind, solar and other innovative sources, and increased energy efficiency, before turning to fossil fuels.

"Utilities will simply need to demonstrate why clean energy would not work whenever they propose to replace or add new generating capacity," he said.

Walz's plan, announced last week, seeks to build on the success of a 2007 law that required Minnesota utilities to get at least 25 percent of their electricity from renewable sources by 2025. The state largely achieved that goal in 2017 thanks to the growth of wind and solar power, and the topic of climate change has only grown hotter, with some proposals like a fully renewable grid by 2030 pushing even faster timelines, hence the new goal for 2050.

But Joel Johnson, a lobbyist for the Minnkota Power Cooperative, testified that the governor's plan is "misguided and unrealistic" even with new technology to capture carbon dioxide emissions from power plants. Johnson added that even the big utilities that have set goals of going carbon-free by mid-century, such as Minneapolis-based Xcel Energy, acknowledge they don't know yet how they'll hit the net-zero electricity by mid-century target they have set.

Minnkota serves northwestern Minnesota and eastern North Dakota.

Tim Sullivan, president and CEO of the Wright-Hennepin Cooperative Electric Association in the Twin Cities area, said the plan is a "bad idea" for the 1.7 million state electric consumers served by cooperatives. He said Minnesota is a "minuscule contributor" to total global carbon emissions, even as the EU plans to double electricity use by 2050 to meet electrification demands.

"The bill would have a devastating impact on electric consumers," Sullivan said. "It represents, in our view, nothing short of a first-order threat to the safety and reliability of Minnesota's grid."

Isaac Orr is a policy fellow at the Minnesota-based conservative think tank, the Center for the American Experiment, which released a report critical of the plan Tuesday. Orr said all Minnesota households would face higher energy costs and it would harm energy-intensive industries such as mining, manufacturing and health care, while doing little to reduce global warming.

"This does not pass a proper cost-benefit analysis," he testified.

Environmental groups, including Conservation Minnesota and the Sierra Club, supported the proposal while acknowledging the challenges, noting that cleaning up electricity is critical to climate pledges in many jurisdictions.

"Our governor has called climate change an existential crisis," said Kevin Lee, director of the climate and energy program at the Minnesota Center for Environmental Advocacy. "This problem is the defining challenge of our time, and it can feel overwhelming."

Rep. Jean Wagenius, the committee chairwoman and Minneapolis Democrat who's held several hearings on the threats that climate change poses, said she expected to table the bill for further consideration after taking more testimony in the evening and would not hold a vote Tuesday.

While the bill has support in the Democratic-controlled House, it's not scheduled for action in the Republican-led Senate. Rep. Pat Garofalo, a Farmington Republican, quipped that it "has a worse chance of becoming law than me being named the starting quarterback for the Minnesota Vikings."

Toronto Flood Cleanup details the citywide response to storm damage after heavy rain, stressing drainage system upgrades, emergency services, transit disruptions, infrastructure repair, financial aid, insurance claims, and climate resilience planning for future weather.

Key Points

Toronto Flood Cleanup is the city's flood response, restoring infrastructure, aiding residents, and upgrading drainage.

✅ Emergency services and public works lead debris removal.

✅ Repairs to roads, bridges, transit, and utilities underway.

✅ Aid, insurance claims, and drainage upgrades prioritized.

Toronto is grappling with significant cleanup efforts following severe storms that unleashed heavy rains and caused widespread flooding across the city. The storms, which hit the area over the past week, have left a trail of damage and disruption, prompting both immediate response measures and longer-term recovery plans.

The intense rainfall began with a powerful storm system that moved through southern Ontario, with Sudbury Hydro crews working to reconnect service as the system pressed toward the GTA, delivering an unprecedented volume of water in a short period. The resulting downpours overwhelmed the city's drainage systems, leading to severe flooding in multiple neighborhoods. Streets, basements, and parks were inundated, with many areas experiencing water levels not seen in recent memory.

Emergency services were quickly mobilized to address the immediate impact of the floods. Toronto’s Fire Services, along with other first responders and skilled utility teams, as Ontario recently sent 200 workers to Florida to help restore power, were deployed to assist residents affected by the rising waters. Rescue operations were carried out to help people trapped in their homes or vehicles, and temporary shelters were set up for those displaced by the flooding.

The storm's impact was felt across various sectors of the city. Public transportation services were disrupted, as strong gusts led to significant power outages in parts of the region, with numerous subway stations and bus routes affected by the high water levels. Major roads were closed due to flooding, causing significant traffic delays and affecting daily commutes for many residents. Local businesses also faced challenges, with some forced to close their doors as a result of the water damage.

The city's infrastructure bore the brunt of the storm's fury. Several key infrastructure components, including roads, bridges, and utilities, suffered damage. The city's water treatment plants and sewage systems were stressed by the volume of water, raising concerns about potential contamination and the need for extensive maintenance and repair work.

In the wake of the flooding, the Toronto Municipal Government has launched a comprehensive cleanup and recovery effort. The city's Public Works Department is spearheading the operation, focusing on clearing debris, repairing damaged infrastructure, and restoring essential services, as Hydro One crews restore power to hundreds of thousands across Ontario. Teams of workers are diligently addressing the damage to roads and bridges, ensuring that they are safe for use and functioning properly.

Efforts are also underway to assist residents and businesses affected by the flooding. Financial aid and support programs are being implemented to help those who have suffered property damage or loss, including customers affected by Toronto power outages as repairs continue. The city is working closely with insurance companies to facilitate claims and provide relief to those in need.

In addition to the immediate cleanup, there is a heightened focus on evaluating and improving the city's flood management systems. The recent storms have highlighted vulnerabilities in Toronto’s infrastructure, prompting calls for enhanced flood prevention measures. City officials and urban planners are assessing the current drainage systems and exploring ways to bolster their capacity to handle future extreme weather events.

The storms have also sparked discussions about the broader implications of climate change and its impact on urban areas. Experts suggest that increasingly severe weather events, including heavy rainfall and flooding, may become more common, as seen with Houston's extended power outage after severe storms, as global temperatures rise. This has led to a call for more resilient and adaptable infrastructure to better withstand such events.

Community organizations and volunteers have played a vital role in the recovery process. Local groups have come together to support their neighbors, providing assistance with cleanup efforts, distributing supplies, and offering emotional support to those affected by the disaster. Their contributions underscore the importance of community solidarity in times of crisis.

As Toronto works towards recovery, there is a clear recognition of the need for a comprehensive strategy to address both the immediate and long-term challenges posed by severe weather events. The city’s response will involve not only repairing the damage caused by this storm but also investing in infrastructure improvements, drawing lessons from London power outage disruption cases to harden critical systems, and adopting measures to mitigate the impact of future floods.

In summary, the severe storms that recently struck Toronto have led to widespread flooding and significant disruption across the city. The immediate response has involved extensive cleanup efforts, damage assessment, and support for affected residents and businesses. Looking ahead, Toronto faces the challenge of enhancing its flood management systems and preparing for the potential impacts of climate change. The collective efforts of emergency services, city officials, and community members will be crucial in ensuring a swift recovery and building resilience against future storms.

EU Electricity Market Reform seeks to curb gas-driven volatility by expanding CfDs and PPAs, decoupling power from gas, and aligning consumer bills with low-cost renewables and nuclear, as Brussels advances market redesign.

Key Points

An EU plan to curb price spikes by expanding long-term contracts and tying bills to cheap renewables.

✅ Expands CfDs and PPAs to lock in predictable power prices

✅ Aims to decouple bills from gas-driven wholesale volatility

✅ Seeks investment certainty for renewables, nuclear, and grids

European Union energy ministers meet on Monday to debate upcoming power market reforms. Brussels is set to propose the revamp next month, but already countries are split over how to "fix" the energy system - or whether it needs fixing at all.

Here's what you need to know.

POST-CRISIS CHANGES
The European Commission pledged last year to reform the EU's electricity market rules, after record-high gas prices - caused by cuts to Russian gas flows - sent power prices soaring during an energy crisis for European companies and citizens.

The aim is to reform the electricity market to shield consumer energy bills from short-term swings in fossil fuel prices, and make sure that Europe's growing share of low-cost renewable electricity translates into lower prices, even though rolling back electricity prices poses challenges for policymakers.

Currently, power prices in Europe are set by the running cost of the plant that supplies the final chunk of power needed to meet overall demand. Often, that is a gas plant, so gas price spikes can send electricity prices soaring.

EU countries disagree on how far the reforms should go.

Spain, France and Greece are among those seeking a deep reform.

In a document shared with EU countries, seen by Reuters, Spain said the reforms should help national regulators to sign more long-term contracts with electricity generators to pay a fixed price for their power.

Nuclear and renewable energy producers, for example, would receive a "contract for difference" (CfD) from the government to provide power during their lifespan - potentially decades - at a stable price that reflects their average cost of production.

Similarly, France suggests, as part of a new electricity pricing scheme, requiring energy suppliers to sign long-term, fixed-price contracts with power generators - either through a CfD, or a private Power Purchase Agreement (PPA) between the parties.

French officials say this would give the power plant owner predictable revenue, while enabling consumers to have part of their energy bill comprised of this more stable price.

Germany, Denmark, Latvia and four other countries oppose a deep reform, and, as nine EU countries oppose reforms overall, have warned the EU against a "crisis mode" overhaul of a complex system that has taken decades to develop.

They say Europe's existing power market is functioning well, and has fostered years of lower power prices, supported renewable energy and helped avoid energy shortages.

Those countries support only limited tweaks, such as making it easier for consumers to choose between fluctuating and fixed-price power contracts.

'DECOUPLE' PRICES?
The Commission initially pitched the reform as a chance to "decouple" gas and power prices in Europe, suggesting a redesign of the current system of setting power prices. But EU officials say Brussels now appears to be leaning towards more modest changes.

A public consultation on the reforms last month steered clear of a deep energy market intervention. Rather, it suggested expanding Europe's use of long-term contracts, outlining a plan for more fixed-price contracts that provide power plants with a fixed price for their electricity, like CfDs or PPAs.

The Commission said this could be done by setting EU-wide rules for CfDs and letting countries voluntarily use them, or require new state-funded power plants to sign CfDs. The consultation mooted the idea of forcing existing power plants to sign CfDs, but said this could deter much-needed investments in renewable energy.

RISKS, REWARDS
Pro-reform countries like Spain say a revamped power market will bring down energy prices for consumers, by matching their bills more closely with the true cost of producing lower-carbon electricity.

France says the aim is to secure investment in low-carbon energy including renewables, and nuclear plants like those Paris plans to build. It also says lowering power prices should be part of Europe's response to massive industrial subsidies in the United States and China - by helping European firms keep a competitive edge.

But sceptics warn that drastic changes to the market could knock confidence among investors, putting at risk the hundreds of billions of euros in renewable energy investments the EU says are needed to quit Russian fossil fuels under its plan to dump Russian energy and meet climate goals.

Energy companies including Engie (ENGIE.PA), Orsted (ORSTED.CO) and Iberdrola (IBE.MC) have said making CfDs mandatory or imposing them retroactively on existing power plants could deter investment and trigger litigation from energy companies.

POLITICAL DEBATE
EU countries' energy ministers discuss the reforms on Monday, before formal negotiations begin.

The Commission, which drafts EU laws, plans to propose the reforms on Mar. 14. After that, EU countries and lawmakers negotiate the final law, which must win majority support from European Parliament lawmakers and a reinforced majority of at least 15 countries.

Negotiations on major EU legislation often take more than a year, but some countries are pushing for a fast-tracked deal. France wants the law to be finished this year.

That has already hit resistance from countries like Germany, highlighting a France-Germany tussle over the scope of reform as they say deeper changes cannot be rushed through, and they would need an "in-depth impact assessment" - something the Commission's upcoming proposal is not expected to include, because it has been drafted so quickly.

The timeline is further complicated by European Parliament elections in 2024. That has raised concerns in reform-hungry states that failure to strike a deal before the election could significantly delay the reforms, if negotiations have to pause until a new EU parliament is elected.

EU Renewable Power Overtakes Fossil Fuels, reflecting a greener energy mix as wind, solar, and hydro expand, cutting CO2 emissions and curbing coal while negative prices rise amid pandemic-driven demand drops.

Key Points

A milestone as renewables surpass fossil power in the EU, driven by wind, solar, hydro growth and pandemic demand.

✅ 40% renewables vs 34% fossil in H1 across 27 EU states

✅ Wind, solar, hydro rose; coal generation fell 32% year-on-year

✅ Lower demand, carbon prices, grid priority boosted clean output

Renewable power for the first time contributed a bigger share in the European generation mix than fossil fuels, as described in Europe's green surge as the fallout from the pandemic cut energy demand.

About 40 percent of the electricity in the first half in the 27 EU countries came from renewable sources, exceeding the global renewables share reported elsewhere, compared with 34 percent from plants burning fossil fuels, according to environmental group Ember in London. As a result, carbon dioxide emissions from the power sector fell 23 percent.

The rise is significant and encouraging for law makers as Europe prepares to spend billions of euros to recover from the virus, with wind power investments underscoring the momentum, and set the bloc on track to neutralize its carbon footprint by the middle of the century.

“This marks a symbolic moment ​in the transition of Europe’s electricity sector,” said Dave Jones, an electricity analyst at Ember. “For countries like Poland and Czech Republic grappling with how to get off coal, there is now a clear way out.”

While power demand slumped, output from wind and solar farms increased, reflecting global wind and solar gains, because more plants came online in breezy and sunny weather. At the same time, wet conditions boosted hydro power in Iberia and the Nordic markets.

Those conditions helped renewables become a rare bright spot throughout the economic tumult this year. In many areas, renewable sources of electricity have priority to the grid, meaning they could keep growing even as demand shrank and other power plants were turned off.

Electricity demand in the EU fell 7 percent overall. Fossil-fuel power generation plunged 18 percent in the first half compared with a year earlier. Renewable generation grew by 11 percent, according to Ember.

Coal was by far the biggest loser in 2020. It’s one of the most-polluting sources of power and its share is slumping in Europe as the price of carbon increases, with renewables surpassing coal in the US illustrating the broader shift, and governments move to cut emissions. Power from coal fell 32 percent across the EU.

Despite the economics, the decision to shut off coal for good will come down to political agreements between producers and governments, while reducing reliance on Russian energy reshapes policy debates.

One consequence of the jump in renewables is that negative prices have increased, as solar is reshaping prices in Northern Europe in similar ways. On particularly windy or sunny days when there isn’t much demand, the grid can be flooded with power. That’s leading wind farms to be shut off and customers to be paid to consume electricity.
