Researchers have developed some of the tiniest solar cells ever made and said the organic material could potentially be painted on to surfaces.

So far, they have managed to pull 11 volts of electricity from a small array of the cells, which are each just a quarter of the size of a grain of white rice, said Xiaomei Jiang of the University of South Florida, who led the research.

"They could be sprayed on any surface that is exposed to sunlight — a uniform, a car, a house," Jiang said in a telephone interview.

"Because it is in a solution, you can design a special spray gun where you can control the size and thickness. You could produce a paste and brush it on," she said.

Eventually, Jiang envisions the solar cells being used as a coating on a variety of surfaces, including clothing. They might generate energy to power small electronic devices or charge a cell phone, for example.

Solar cells, which convert energy from the sun into electricity, are in increasing demand amid unstable gas prices and worries over global warming.

Most conventional solar cells are made up of silicon wafers, a brittle substance that limits where they can be placed.

Many teams of scientists are working on different ways to make solar cells more flexible in the hopes of taking better advantage of energy from the sun.

The tiny cells from Jiang's lab are made from an organic polymer that has the same electrical properties of silicon wafers but can be dissolved and applied to flexible materials.

"The main components are carbon and hydrogen — materials that are present in nature and are environmentally friendly," Jiang said.

In research published in the Journal of Renewable and Sustainable Energy, Jiang and colleagues showed an array of 20 of these cells could generate 7.8 volts of electricity, about half the power needed to run a microscopic sensor for detecting dangerous chemicals and toxins.

Her team is now refining the manufacturing process with the hope of doubling that output to 15 volts. "It's a matter of months," Jiang said.

Energy prices trigger EU inflation, poor worst hit

EU Energy Price Surge is driving up electricity and gas costs, inflation, and cost of living across the EU, prompting tax cuts, price caps, subsidies, and household support measures in France, Italy, Spain, and Germany.

 

Key Points

A surge in EU gas and electricity costs driving inflation and prompting government subsidies, tax cuts, and price caps.

✅ Low-income EU households now spend 50-70 percent more on energy.

✅ Governments deploy tax cuts, price caps, and direct subsidies.

✅ Gas-dependent power markets drive electricity price spikes.

 

Higher energy prices, including for natural gas, are pushing up electricity prices and the cost of living for households across the EU, prompting governments to cut taxes and provide financial support to the tune of several billion euros.

In the United Kingdom, households are bracing for high winter energy bills this season.

A series of reports published by Cambridge Econometrics in October and November 2022 found that households in EU countries are spending much more on energy than in 2020 and that governments are spending billions of euros to help consumers pay bills and cut taxes.

In France, for example, the poorest households now spend roughly one-third more on energy than in 2020. Between August 2020 and August 2022, household energy prices increased by 37 percent, while overall inflation increased by 9.2 percent.

“We estimate that the increase in household energy prices make an average French household €410 worse off in 2022 compared to 2020, mostly due to higher gas prices,” said the report.

In response to rising energy prices, the French government has adopted price caps and support measures forecast to cost over €71 billion, equivalent to 2.9 percent of French GDP, according to the U.K.-based consultancy.

In Italy, fossil fuels alone were responsible for roughly 30 percent of the country’s annual rate of inflation during spring 2022, according to Cambridge Econometrics. Unlike in other European countries, retail electricity prices have outpaced other energy prices in Italy and were 112 percent higher in July 2022 than in August 2020, the report found. Over the same time period, retail petrol prices were up 14 percent, diesel up 22 percent, and natural gas up 42 percent.

We estimate that households in the lowest-income quintile now spend about 50 percent more on energy than in 2020.

“We estimate that before government support, an average Italian household will be spending around €1,400 more on energy and fuel bills this year than in 2020,” the report said. “Low-income households are worse affected by the increasing energy prices: we estimate that households in the lowest-income quintile now spend about 50 percent more on energy than in 2020.”

Electricity production in Italy is dominated by natural gas, which has also led to a spike in wholesale electricity prices. In 2010, natural gas accounted for 50 percent of all electricity production. The share of natural gas fell to 33 percent in 2014, but then rose again, reaching 48 percent in 2021, and 56 percent in the first half of 2022, according to the report, as gas filled the gap of record low hydro power production in 2022.

In Spain, where electricity prices have seen extreme spikes, low-income households are now spending an estimated 70% more on energy than in 2020, according to Cambridge Econometrics.


Low-income squeeze
In Spain, low-income households are now spending an estimated 70% more on energy than in 2020, according to Cambridge Econometrics. It noted that the Spanish government has intervened heavily in energy markets by cutting taxes, introducing cash transfers for households, and capping the price of natural gas for power generators. The latter has led to lower electricity prices than in many other EU countries.

These support measures are forecast to cost the Spanish government over €35 billion, equivalent to nearly 3 percent of Spain’s GDP. Yet consumers will still feel the burden of higher costs of living, and rolling back electricity prices may prove difficult in the near term.

In March, electricity prices alone were responsible for 45 percent of year-on-year inflation in Spain but prices have since fallen as a result of government intervention, Cambridge Econometrics said. Between May and July, fossil fuels prices accounted for 19-25 percent of the overall inflation rate, and electricity prices for 16 percent.


Support measures
Rising inflation is also a real challenge in Germany, Europe’s largest economy, where German power prices have surged this year, adding pressure. Also there, higher gas prices are to blame.

“We estimate that the increase in energy prices currently make an average household €735 worse off in 2022 compared to 2020, mostly due to higher gas prices,” Cambridge Econometrics said, in a report focused on Germany.

The German government has introduced a number of support measures in order to help households, businesses and industry to pay energy bills, amid rising heating and electricity costs for consumers, including price caps that are expected to take effect in March next year. Moreover, households’ energy bills for December this year will be paid by the state. According to the report, these interventions will mitigate the impact of higher prices “to some extent”, but the aid measures are forecast to cost the government nearly 5 percent of GDP.


Fossil-fuel effect
In addition to gas, higher coal prices have also pushed up inflation in some countries, and U.S. electricity prices have reached multi-decade highs as inflation endures.

In Poland, which is heavily dependent on coal for electricity generation, fossil fuels accounted for roughly 40 percent of Poland’s overall year-on-year inflation rate in June 2022, which stood at over 14 percent, the consultancy said.

The price of household coal, which is widely used in heating Polish homes, increased by 157 percent between August 2021 and August 2022.

Higher energy prices in Poland are partly due to Polish and EU sanctions against Russian gas and coal. Other drivers are the weakening of the Polish zloty against the U.S. dollar and the euro, and the uptick in global demand after COVID-19 lockdowns, said Cambridge Econometrics.

Electricity prices have risen at a much slower pace than energy for transport and heating, with an annualized increase of 5.1 percent.

SaskPower eyes buying $300M worth of electricity from Flying Dust First Nation

SaskPower-Flying Dust flare gas power deal advances a 20 MW, 20-year Power Purchase Agreement, enabling grid supply from FNPA-backed generation, supporting renewable strategy, lower carbon footprint targets, and First Nation economic development in Saskatchewan.

 

Key Points

A 20 MW, 20-year PPA converting flare gas to grid power, with SaskPower buying from Flying Dust First Nation via FNPA.

✅ 20 MW of flare gas generation linked to Saskatchewan's grid

✅ 20-year term; about $300M total value to SaskPower

✅ FNPA-backed project; PPA targeted in 6-12 months

 

An agreement signed between SaskPower, which reported $205M income in 2019-20, and Flying Dust First Nation is an important step toward a plan that could see the utility buy $300 million worth of electricity from Flying Dust First Nation, according to Flying Dust's chief.

"There's still a lot of groundwork that needs to be done before we get building but you know we're a lot closer today with this signing," Jeremy Norman told reporters Friday.

Norman's community was assisted by the First Nations Power Authority (FNPA), a non-profit that helps First Nations get into the power sector, with examples like the James Bay project showing what Indigenous ownership can achieve.

The agreement signed Friday says SaskPower will explore the possibility of buying 20 megawatts of flare gas power from FNPA, which it will look to Flying Dust to produce.

20-year plan

The proposed deal would span 20 years and cost SaskPower around $300 million over those years, as the utility also explores geothermal power to meet 2030 targets.

The exact price would be determined once a price per metawatt is brought forward.

"We won't be able to do this ourselves," Norman said.

Flare gas power generation works by converting flares from the oil and gas sector into electricity. Under this plan, SaskPower would take the electricity provided by Flying Dust and plug it into the provincial power grid, complementing a recent move to buy more power from Manitoba Hydro to support system reliability.

"This is a great opportunity as we advance our renewable strategy, including progress on doubling renewables by 2030, and try to achieve a lower carbon footprint by 2030 and beyond," Marsh said.

Norman said the business deal presents an opportunity to raise money to reinvest into the First Nation for things like more youth programming.

For the next steps, both parties will need to sign a power purchase agreement that spells out the exact prices for the power generation.

Marsh expects to do so in the next six to 12 months, with development of the required infrastructure to take place after that.

Alberta creates fund to help communities hit by coal phase-out

Alberta Coal Community Transition Fund backs renewables, natural gas, and economic diversification, offering grants, workforce retraining, and community development to municipalities and First Nations as Alberta phases out coal-fired power by 2030.

 

Key Points

A provincial grant helping coal-impacted communities diversify, retrain workers, and transition to renewables by 2030.

✅ Grants for municipalities and First Nations

✅ Supports diversification and job retraining

✅ Focus on renewables, natural gas, and new sectors

 

The Coal Community Transition Fund is open to municipalities and First Nations affected as Alberta phases out coal-fired electricity by 2030 under the federal coal plan to focus on renewables and natural gas.

Economic Development Minister Deron Bilous says the government wants to ensure these communities thrive through the transition, aligning with views that fossil-fuel workers support the energy transition across the economy.

“Residents in our communities have concerns about the transition away from coal, even as discussions about phasing out fossil fuels in B.C. unfold nationally,” Rod Shaigec, mayor of Parkland County, said.

“They also have ideas on how we can mitigate the impacts on workers and diversify our economy, including clean energy partnerships to create new employment opportunities for affected workers. We are working to address those concerns and support their ideas. This funding means we can make those ideas a reality in various economic sectors of opportunity.”

The coal-mining town of Hanna, northeast of Calgary, has already received $450,000 through the program to work on economic diversification, exploring options like bridging the Alberta-B.C. electricity gap that could support new industries.

The application deadline for the coal transition fund is the end of November.

A provincial advisory panel is also expected to report back this fall on ways to create new jobs and retrain workers during the coal phase-out.

In North Carolina, unpaid electric and water bills are driving families and cities to the financial brink

North Carolina Utility Arrears Crisis strains households and municipal budgets as COVID-19 cuts jobs; unpaid utility bills mount, shutoffs loom, and emergency aid, unemployment benefits, and CARES Act relief lag behind rising arrears across cities.

 

Key Points

A COVID-19 driven spike in unpaid utility bills, threatening households and municipal budgets as federal aid lapses.

✅ 1 million families behind on power, water, sewage bills

✅ $218M arrears accrued April to June, double last year

✅ Municipal utilities face shutoffs, budget shortfalls

 

As many as 1 million families in North Carolina have fallen behind on their electric, water and sewage bills, a sign of energy insecurity threatening residents and their cities with severe financial hardship unless federal lawmakers act to approve more emergency aid.

The trouble stems from the widespread economic havoc wrought by the coronavirus, which has left millions of workers out of a job and struggling to cover their monthly costs as some states moved to suspend utility shut-offs to provide relief. Together, they’ve been late or missed a total of $218 million in utility payments between April 1 and the end of June, according to data released recently by the state, nearly double the amount in arrears at this time last year.

In some cases, cities that own or operate their own utilities have been forced to absorb these losses, as some utilities reconnected customers to prevent harm, creating a dire situation in which the government’s attempt to save people from the financial brink instead has pushed municipal coffers to their own breaking point.

In Elizabeth City, N.C., for example, about 2,500 residents haven’t paid their electric bills on time, according to Richard Olson, the city manager. The late payments at one point proved so problematic that Olson said he calculated Elizabeth City wouldn’t have enough money to pay for its expenses in July. In response, city leaders requested and obtained a waiver from a statewide order, similar to New York’s disconnection moratorium, issued in March, that protects people from being penalized for their past-due utility bills.

The predicament has presented unique budget challenges throughout North Carolina, while illustrating the consequences of a cash crunch plaguing the entire country, where proposals such as a Texas electricity market bailout surfaced following severe grid stress. State and federal leaders have extended a range of coronavirus relief programs since March to try to help people through the pandemic. But the money is limited and restricted — and it’s not clear whether more help from Congress is on the way — creating a crisis in which the nation’s economic woes are outpacing some of the aid programs adopted to combat them.

“We are entering a phase where the utilities [may] be able to shut off power, but what was propping up people’s economic lives, the unemployment benefits and Cares Act support, won’t be there,” said Paul Meyer, the executive director of the North Carolina League of Municipalities.

White House, GOP in disarray over coronavirus spending plan as deadline nears on expiring emergency aid

The future of that safety-net support — and other federal aid — hangs in the balance as lawmakers returned to work this week in their final sprint ahead of the August recess. The White House and congressional leaders are split over the contours of the next coronavirus relief package, including the need to extend more aid to cities and states as some utilities have waived fees to help customers, and reauthorize an extra $600 in weekly unemployment payments that were approved as part of the Cares Act in March.

Outside Washington, workers, businesses and government officials nationwide have pleaded with federal lawmakers to renew or expand those programs. Last week, Roy Cooper, the Democratic governor of North Carolina, urged Congress to act swiftly and adopt a wide array of new federal spending, including proposals for DOE nuclear cleanup funding, stressing in a letter that the “actions you take in the next few weeks are vital to our ability to emerge from this crisis. ”

German renewables deliver more electricity than coal and nuclear power for the first time

Germany renewable energy milestone 2019 saw wind, solar, hydropower, and biomass outproduce coal and nuclear, as low gas prices and high CO2 costs under the EU ETS reshaped the electricity mix, per Fraunhofer ISE.

 

Key Points

It marks H1 2019 when renewables supplied 47.3% of Germany's electricity, surpassing coal and nuclear.

✅ Driven by high CO2 prices and cheap natural gas

✅ Wind and solar output rose; coal generation declined sharply

✅ Flexible gas plants outcompeted inflexible coal units

 

In Lippendorf, Saxony, the energy supplier EnBW is temporarily taking part of a coal-fired power plant offline. Not because someone ordered it — it simply wasn't paying off. Gas prices are low, CO2 prices are high, and with many hours of sunshine and wind, renewable methods are producing a great deal of electricity as part of Germany's energy transition now reshaping operations. And in the first half of the year there was plenty of sun and wind.

The result was a six-month period in which renewable energy sources, a trend echoed by the EU wind and solar record across the bloc, produced more electricity than coal and nuclear power plants together. For the first time 47.3% of the electricity consumers used came from renewable sources, while 43.4% came from coal-fired and nuclear power plants.

In addition to solar and wind power, renewable sources also include hydropower and biomass. Gas supplied 9.3%, reflecting how renewables are crowding out gas across European power markets, while the remaining 0.4% came from other sources, such as oil, according to figures published by the Fraunhofer Institute for Solar Energy Systems in July.

Fabian Hein from the think tank Agora Energiewende stresses that the situation is only a snapshot in time, with grid expansion woes still shaping outcomes. For example, the first half of 2019 was particularly windy and wind power production rose by around 20% compared to the first half of 2018.

Electricity production from solar panels rose by 6%, natural gas by 10%, while the share of nuclear power in German electricity consumption has remained virtually unchanged despite a nuclear option debate in climate policy.

Coal, on the other hand, declined. Black coal energy production fell by 30% compared to the first half of 2018, lignite fell by 20%. Some coal-fired power plants were even taken off the grid, even as coal still provides about a third of Germany's electricity. It is difficult to say whether this was an effect of the current market situation or whether this is simply part of long-term planning, says Hein.

 

Activists storm German mine in anti-coal protest

It is clear, however, that an increased CO2 price has made the ongoing generation of electricity from coal more expensive. Gas-fired power plants also emit CO2, but less than coal-fired power plants. They are also more efficient and that's why gas-fired power plants are not so strongly affected by the CO2 price

The price is determined at a European level and covers power plants and energy intensive industries in Europe. Other areas, such as heating or transport are not covered by the CO2 price scheme. Since a reform of CO2 emissions trading in 2017, the price has risen sharply. Whereas in September 2016 it was just over €5 ($5.6), by the end of June 2019 it had climbed to over €26.

 

Ups and downs

Gas as a raw material is generally more expensive than coal. But coal-fired power plants are more expensive to build. This is why operators want to run them continuously. In times of high demand, and therefore high prices, gas-fired power plants are generally started up, as seen when European power demand hit records during recent heatwaves, since it is worth it at these times.

Gas-fired power plants can be flexibly ramped up and down. Coal-fired power plants take 11 hours or longer to get going. That's why they can't be switched on quickly for short periods when prices are high, like gas-fired power plants. In the first half of the year, however, coal-fired power plants were also ramped up and down more often because it was not always worthwhile to let the power plant run around the clock.

Because gas prices were particularly low in the first half of 2019, some gas-fired power plants were more profitable than coal-fired plants. On June 29, 2019, the gas price at the Dutch trading point TTF was around €10 per megawatt hour. A year earlier, it had been almost €20. This is partly due to the relatively mild winter, as there is still a lot of gas in reserve, confirmed a spokesman for the Federal Association of the Energy and Water Industries (BDEW). There are also several new export terminals for liquefied natural gas. Additionally, weaker growth and trade wars are slowing demand for gas. A lot of gas comes to Europe, where prices are still comparatively high, reported the Handelsblatt newspaper.

The increase in wind and solar power and the decline in nuclear power have also reduced CO2 emissions. In the first half of 2019, electricity generation emitted around 15% less CO2 than in the same period last year, reported BDEW. However, the association demands that the further expansion of renewable energies should not be hampered. The target of 65% renewable energy can only be achieved if the further expansion of renewable energy sources is accelerated.

UK electricity and gas networks making ‘unjustified’ profits

UK Energy Network Profits are under scrutiny as Ofgem price controls, Citizens Advice claims, and National Grid margins spark debate over monopolies, allowed returns, consumer bills, rebates, and future investment under tougher regulation.

 

Key Points

UK Energy Network Profits are returns set by Ofgem for regulated grid operators, shaping consumer bills and investment

✅ Ofgem sets allowed returns for monopoly networks via price controls

✅ Dispute over interest rates, bond yields, and risk premiums

✅ Reforms proposed: shorter controls, tougher investor incentives

 

Companies that run Britain’s electricity and gas networks, including National Grid, are making “eye-watering” profits at the expense of households, according to a well-known consumer group.

Citizens Advice believes £7.5bn in “unjustified” profits should be returned to consumers who pay for network costs via their electricity and gas bills, with parallels seen in a deferred BC Hydro costs report abroad, although its figures have been contested by the energy industry and regulator.

Ownership of electricity and gas networks came under the spotlight in the run-up to June’s general election, after the Labour party said in its manifesto it would bring both national and regional grid infrastructure to back into public ownership, amid wider debates about grid privatization concerns elsewhere, over time.

Electricity sector privatisation began in 1990 and the gas industry was privatised in 1986. Energy network companies — which own and operate the cables and wires that help deliver electricity and gas to homes and businesses — are in effect monopolies that are regulated by Ofgem. Ofgem evaluates what their costs, including the cost of capital to finance investments, might be over an eight-year “price control” period, similar to determinations like the OEB decision on Hydro One rates in Ontario, Canada. Citizens Advice claims many of the regulator’s calculations for the most recent price control went “considerably in networks’ financial favour”.

It believes assumptions Ofgem made about factors such as the future path of interest rates and returns on government bonds were too generous, with international contrasts like power theft challenges in India illustrating different risk contexts, as was the regulator’s assessment of the risk associated with operating a network company. 

These “generous” assumptions will lead to network companies making average profit margins of 19 per cent and an average return of 10 per cent for their investors at the expense of consumers, Citizens Advice claims in a report published on Wednesday, which recommends a shorter price control period to allow for more accurate forecasting.

“Decisions made by Ofgem have allowed gas and electricity network companies to make sky-high profits that we’ve found are not justified by their performance,” said Gillian Guy, chief executive of Citizens Advice. Ofgem defended its regulatory regime, saying it helped to cut costs, improve reliability and customer satisfaction. 

“Ofgem has already cut costs to consumers by 6 per cent in the current price control and secured a rebate of over £4.5bn from network companies and is engaging with the industry to deliver further savings, with some regions seeing Ontario electricity rate reductions for businesses as well,” said Dermot Nolan, chief executive of the energy regulator.

Mr Nolan insisted the next price controls would be “tougher for investors”. The current price controls for the gas and electricity transmission networks, plus gas distribution, run until 2021 and until 2023 for local electricity distribution networks.

“While we don’t agree with its modelling and the figures it has produced, the Citizens Advice report raises some important issues about network regulation which will be addressed in the next control,” Mr Nolan said.

The Energy Networks Association, a trade body, refuted the claims of Citizens Advice, insisting that costs had fallen by 17 per cent in real terms since privatisation. The current regulatory framework was established after a public consultation, it said, adding that today’s report repeated several old claims that had previously been rejected by the Competition and Markets Authority.

“Our energy networks are among the most reliable and lowest cost in the world and their performance has never been better. In the next six years energy network companies are forecasted to deliver £45bn of investment in the UK economy,” a spokesman for the networks association added. National Grid said that since 2013 it had generated savings of £460m for bill payers.
