Changing our climate for the worse? That's the easy part. But changing human minds and behaviour — that turns out to be much, much harder.

No matter how much confidence scientists have in the truth of their global warnings, getting the message out to the folks who are actually wrecking the planet has proved to be a far more challenging proposition. Cars still jam the streets, energy consumption increases, polluters sow doubt and denial and, as the Copenhagen summit on climate change nears, politicians still prevaricate as if there were an endless succession of tomorrows.

While there may well be an apocalypse looming on the far horizon, dire prophecies just don't cut it in the here-and-now of consumer culture. So forget the grim 100-year predictions for a second. The crisis at this very moment seems more like a crisis of communication.

Even the chair of the David Suzuki Foundation, James Hoggan, agrees: "Whether it's the scientific community, environmental groups, politicians, the media or business leaders, we haven't done a great job of conveying accurate scientific information to the public on the risks of climate change — or, indeed, of even conveying what climate change is."

Over the decades the climate-change war has been waged, many tactics used to soften up the masses have been unproductive at best and downright discouraging at worst. Even if you believe doomsday is coming, is it really such a good idea to talk it up and wallow in the death and destruction that will result if we don't change our awful ways and acknowledge Al Gore's inconvenient truth?

Such pessimistic predictions may have seemed effective as a way of winning attention (and the Nobel). But if the goal is to motivate people to useful action, say those who are experienced in environmental communication, it calls for something new.

"People have a finite capacity for worry," says Mr. Hoggan, the author of Do the Right Thing: PR Tips for a Skeptical Public . "When you overwhelm people with catastrophe, you don't actually engage them — you just produce an emotional numbness."

That's an intellectual evolution that Mr. Suzuki himself has gone through. His widely viewed TV series The Nature of Things once tended to depict nature as a beautiful pristine thing that bad humans habitually destroyed. Even now, his enemies feel able to undermine his mainstream scientific views by dismissing him as a merchant of doom.

Yet the current incarnation of Mr. Suzuki, in keeping with his foundation's communication techniques, has shifted from the dependable jeremiads of old to a message of everyday hope and more immediate usefulness. Last year, he co-wrote David Suzuki's Green Guide, a book that comes to grips with climate change through small-scale lifestyle adjustments such as biodegradable carpeting and energy-efficient appliances.

"I believe that one has to keep warning [that] the signs are there, the science is in," Mr. Suzuki said when the book came out. "But I realized years ago that you can get people to respond to fear, but you can't sustain it, because it's too soul-destroying."

So what will people respond to when fear doesn't do it? Mark van Vugt is a psychologist who teaches at VU University Amsterdam, and he's part of an emerging group of cognitive scientists studying the sometimes uneasy relationship between climate-change messaging and the workings of the brain.

He says the announcements to be made by global leaders in Copenhagen are of much less consequence than the decisions that are being shaped in the complex minds of ordinary human beings.

"It's very hard to look at a climate-change conference as a primary driver of individual behaviour," Dr. van Vugt says. "Copenhagen is about political solutions, but the environmental issues remain inherently uncertain for most people. So what we have to do is translate these issues into something meaningful at the individual level."

Acquiring information is the basic way the brain deals with uncertainty, and with a subject as complex and contested as long-term climate change, Dr. van Vugt believes the best approach is to localize the discussion: Make it less about far-off glaciers, because people find it hard to cope with a problem they can't easily influence, and more about local parks, forests or air quality.

Any kind of message for change, he believes, must focus on personal identity and our need to belong: "We're influenced by significant others and want to look good to our neighbours and friends."

So a good way to persuade people to reduce electrical consumption is to let them compare their rates with the rest of the community: Have utility bills award a smiley face to those whose consumption is lower than their neighbours and a frowning face to those who are profligate. People then will reduce without any other external motivator, Dr. van Vugt says.

But good behaviour at the individual level won't last if institutional behaviour is untrustworthy — environmental groups must not overstate a threat; scientists can't be seen to adjust data, even in a good cause (as researchers from the International Panel on Climate Change were recently accused of doing); businesses must not act as though they're a law onto themselves; and governments can't preach one thing and then do another.

"Suppose it turns out that the recyclables and organics we've been sorting and separating are just being tossed into one big garbage heap — well, that's a recipe for disaster," Dr. van Vugt says. "You've created goodwill only to destroy it."

While environmentally friendly behaviours are often presented as something altruistic and selfless, he suggests that incentives are key to any successful strategy. "Our primary motivation is to get ahead of others, to see ourselves rewarded for good behaviour while bad behaviour gets punished." So it doesn't hurt to awaken some of this potential goodness by, say, offering a free bus pass for those prepared to be wooed to public transit.

At the same time, it's useful to make green products more luxurious rather than crafting an image of asceticism and self-conscious suffering. "A nice, well-made mountain bike can cost as much as a car and may become a status symbol for just that reason," Dr. van Vugt says. This is what psychologists refer to as signaling potential: Look at me, I'm green and rich and sexy.

Orthodox environmentalists may shudder at the thought, and question the ability of sexy status symbols to stop the seas from rising. Yet the attractiveness of self-denial has proved to be a hard sell to those used to the comforts of our present wastefulness.

"The evidence so far is profoundly against the notion of sacrifice as a success strategy," designer Bruce Mau says. "We've been saying for decades, 'Get out of your cars,' but in not one of those years have there been fewer cars."

For Mr. Mau, solving the problems of climate starts with smart design — carpeting with its own 1-800 number that you call when it needs recycling, a Tesla electric car that looks more beautiful than a Ferrari, and buses that come with cup holders so you don't feel like you're downgrading quite so much from your car.

"If you describe a sustainable future in negative terms," he says, "and if you highlight what it's going to cost them, people aren't going to move there. Doom-and-gloom is a dead end."

The beauty of sustainability has an undeniable appeal. But between the aesthetics and the ascetics of climate change, there's still a lot of room to manoeuvre. A considerable amount of public goodwill was arguably wasted by the campaign to switch from incandescent bulbs to stylish compact fluorescents, a relatively low-impact improvement.

Those who listened attentively to the noisy messaging that promoted the switch to the compact fluorescents may well feel like their effort was wasted — and their commitment could be harder to summon for a more significant shift, such as reducing beef consumption by half. Politicians, after all, fear beef-industry interests, while the incandescent-bulb lobby is relatively powerless.

As the director of the Center for Climate Change Communication at George Mason University in Virginia, Edward Maibach has studied the diverse effects of environmental messaging. He is convinced that changing human behaviour isn't as challenging as many people — certainly many politicians — now believe.

He can tell you from his polling data that when people are asked about changing their behaviour and reducing energy use in response to climate change, 40 per cent of those surveyed report it had no negative impact on their lives — and 30 per cent actually say it improved their quality of life.

From this, he concludes that "there's a collectivist spirit out there that's waiting to be reactivated. People are waiting to be asked to sacrifice. By and large, politicians are fearful about doing the right thing about greenhouses gases because they think they'll be thrown out of office. Yet we've shown that for every one person who'll get upset if you reduce emissions, two and a half will stand up and applaud."

Political leaders who resist the gospel of self-sacrifice like to talk instead about lucrative opportunities — all those Obama-esque "green jobs" to be found in building solar panels and wind farms, retrofitting drafty houses and remaking cities for public transit while (bonus points here) ending dependence on foreign oil.

They don't bother pointing out that our democracy-driven tentativeness has allowed a more decisive China to begin setting itself up as the leading producer of wind energy, solar-panel equipment and electric vehicles.

While waiting for our politicians to see the light, Dr. Maibach encourages citizens to take actions that make green behaviour appear to be the rule, not the exception. Individuals will give up in despair if they think they're engaged in a thankless task of changing the world on their own.

Hope and optimism come from a public display of commitment — Dr. Maibach cites simple school-based programs where parents ask fellow parents not to idle their cars while waiting for their children, explain the reasoning behind their request and perhaps offer a stick-on decal to those who will take the non-idling pledge.

He says the public pledge by itself makes it three times more likely that potential do-gooders will follow through on their good intentions. And from creating that kind of group effect, it then becomes easier to change public policy. "Once you can develop this behaviour and show it to be the social norm, it enables politicians to change the laws more easily."

That is certainly a tactic the David Suzuki Foundation is turning to in its messaging, especially as the Stephen Harper government has shied away from a commitment to environmentalists' cause. The foundation aims to work with government in a non-partisan way, and yet Mr. Hoggan says that when he goes to Copenhagen, "I'm going to tell the media exactly what I think about our government's failure on climate change."

Though the Prime Minister purports to speak for Canada, polls show that a majority of Canadians want stronger action from the government, and this allows groups such as the David Suzuki Foundation to appropriate the Team Canada brand — drawing attention to the negative international response Canada's policies generate internationally (Canadians hate being seen as bad guys) while featuring concerned athletes on the Suzuki website who will challenge Conservative climate policies from an educated-jock perspective (global warming means cancelled ski races).

And thus the Canadian environmental movement, far from being marginal or radical, is seen at its most patriotic and mainstream.

All these feel-good tactics may be useful in garnering more widespread support. But will they genuinely be effective in combating climate change?

The Young Greens of the Green Party don't seem to think so. They recently mounted a more outraged and outrageous 1960s-style campaign, with the support of Green Party Leader Elizabeth May, that used the attention-getting slogan, "Your parents f*cked up the planet — it's time to do something about it. Live green, vote Green."

So it's not all happy faces out there. David McKnight, a journalism professor at the University of New South Wales, criticizes environmentalists for being "a rather elite movement, aimed at symbolic actions to attract media attention and at lobbying government."

He believes (and many in the environmental movement would agree) that the most effective messaging will come from a broader-based movement, similar to the anti-war campaign of the 1960s, that puts hundreds of thousands of people on the streets.

Milan Ilnyckyj, an Ottawa-based blogger on environmental issues, argues that there should be a greater focus on the issue of morality, which is to say immorality.

"If we can accept that climate change causes harm to current and future generations," he writes, "the argument that polluters have some right to keep behaving as they have in the past weakens considerably."

Echoing that thought, William Rees of the University of British Columbia's School of Community and Regional Planning suggests that the international community should develop ways to prosecute governments for criminal negligence on environmental issues.

Still, even this approach presupposes that science and politics in the end can speak the same language. And that's an assumption that doesn't sit well with Kevin DeLuca, a professor of communications at the University of Utah.

"The raison d'être of science is doubt," he says. "But doubt is fatal in politics." Doubt opens the doors for debate about climate change, and endless debate prolongs inaction indefinitely.

Environmentalists look for ways to appeal to a mass audience, and come up with an upbeat message about satisfying self-interest and feeling good. "And so you end up with a spirit-of-the-apocalypse message veiled in a 'don't worry, be happy' conclusion," Prof. DeLuca notes.

He has no confidence in such a contrivance and, unlike most environmentalists, he says he can't put on a happy face even if strategy seems to demand it.

"The problem with the happy-face message is that the future isn't going to be happy. The Earth can get along without people - people can't get along without the Earth."

But that's a message no one wants to hear.

UK windfarms generate record amount of electricity during Storm Malik

UK Wind Power Record as Storm Malik boosts renewable electricity, with National Grid reporting 19,500 megawatts in Scotland, cutting fossil fuel use and easing market prices on the path toward net zero targets.

 

Key Points

An all-time peak in UK wind generation, reaching 19,500 MW during Storm Malik, supplying over half of electricity.

✅ Peak: 19,500 MW, over 50% of UK electricity.

✅ Driven by Storm Malik; strongest winds in Scotland.

✅ Lowered market prices; reduced fossil fuel generation.

 

The UK’s windfarms generated a new record for wind power generation over the weekend as Storm Malik battered parts of Scotland and northern England.

Wind speeds of up to 100 miles an hour recorded in Scotland's wind farms helped wind power generation to rise to a provisional all-time high of more than 19,500 megawatts – or more than half the UK’s electricity – according to data from National Grid.

National Grid’s electricity system operator said that although it recognised the new milestone towards the UK’s ‘net zero’ carbon future, where wind is leading the power mix according to recent analyses, it was “also thinking of those affected by Storm Malik”.

The deadly storm caused widespread disruption over the weekend, leaving thousands without electricity and killing two people.

Many of the areas affected by Storm Malik were also hit in December by Storm Arwen, which caused the most severe disruption to power supplies since 2005, leaving almost a million homes without power for up to 12 days.

The winter storms have followed a summer of low wind power generation across the UK and Europe, even though wind produced more electricity than coal for the first time in 2016, which caused increased use of gas power plants during a global supply shortfall.

Gas markets around the world reached record highs due to rising demand for gas, and UK electricity prices hit a 10-year high as economies have rebounded from the economic shock of the Covid-19 pandemic. In the UK, electricity market prices reached an all-time high of more than £424.60 a megawatt-hour in September, compared with an average price of £44/MWh in the same month the year before.

The UK’s weekend surge in renewable electricity helped to provide a temporary reprieve from its heavy reliance on fossil fuel generation in recent months, and on some days wind has been the main source of UK electricity, which has caused market prices to reach record highs.

The market price for electricity on Saturday fell to £150.59 pounds a megawatt-hour, the lowest level since 3 January, while UK peak power prices have risen with the price for power on Sunday, when wind was expected to fall, jumping to more than £193.50/MWh.

The new wind generation record bettered a high recorded last year when the gusty May bank holiday weekend recorded 17.6GW.

Construction of expanded Hoa Binh Hydropower Plant to start October 2020

Expanded Hoa Binh Hydropower Plant increases EVN capacity with 480MW turbines, commercial loan financing, grid stability, flood control, and Da River reliability, supported by PECC1 feasibility work and CMSC collaboration on site clearance.

 

Key Points

A 480MW EVN expansion on the Da River to enhance grid stability, flood control, and seasonal water supply in Vietnam.

✅ 480MW, two turbines, EVN-led financing without guarantees

✅ Improves frequency modulation and national grid stability

✅ Supports flood control and dry-season water supply

 

The extended Hoa Binh Hydropower Plant, which is expected to break ground in October 2020, is considered the largest power project to be constructed this year, even as Vietnam advances a mega wind project planned for 2025.

Covering an area of 99.2 hectares, the project is invested by Electricity of Vietnam (EVN). Besides, Vietnam Electricity Power Projects Management Board No.1 (EVNPMB1) is the representative of the investor and Power Engineering Consulting JSC 1 (EVNPECC1) is in charge of building the feasibility report for the project. The expanded Hoa Binh Hydro Power Plant has a total investment of VND9.22 trillion ($400.87 million), 30 per cent of which is EVN’s equity and the remaining 70 per cent comes from commercial loans without a government guarantee.

According to the initial plan, EVN will begin the construction of the project in the second quarter of this year and is expected to take the first unit into operation in the third quarter of 2023, a timeline reminiscent of Barakah Unit 1 reaching full power, and the second one in the fourth quarter of the same year.

Chairman of the Committee for Management of State Capital at Enterprises (CMSC) Nguyen Hoang Anh said that in order to start the construction in time, CMSC will co-operate with EVN to work with partners as well as local and foreign banks to mobilise capital, reflecting broader nuclear project milestones across the energy sector.

In addition, EVN will co-operate with Hoa Binh People’s Committee to implement site clearance, remove Ba Cap port and select contractors.

Once completed, the project will contribute to preventing floods in the rainy season and supply water in the dry season. The plant expansion will include two turbines with the total capacity of 480MW, similar in scale to the 525-MW hydropower station China is building on a Yangtze tributary, and electricity output of about 488.3 million kWh per year.

In addition, it will help improve frequency modulation capability and stabilise the frequency of the national electricity system through approaches like pumped storage capacity, and reduce the working intensity of available turbines of the plant, thus prolonging the life of the equipment and saving maintenance and repair costs.

Built in the Da River basin in the northern mountainous province of Hoa Binh, at the time of its conception in 1979, Hoa Binh was the largest hydropower plant in Southeast Asia, while projects such as China’s Lawa hydropower station now dwarf earlier benchmarks.

The construction was supported by the Soviet Union all the way through, designing, supplying equipment, supervising, and helping it go on stream. Construction began in November 1979 and was completed 15 years later in December 1994, when it was officially commissioned, similar to two new BC generating stations recently brought online.

Chester County Landfill Converts Methane to Renewable Gas

SECCRA Waga Energy RNG Partnership captures landfill methane with WAGABOX, upgrades biogas to pipeline-quality RNG, enables grid injection, and lowers greenhouse gas emissions, delivering sustainable energy to Chester County homes and businesses.

 

Key Points

A joint project converting landfill methane to RNG with WAGABOX, cutting emissions and supplying local heat.

✅ WAGABOX captures and purifies landfill gas to RNG

✅ Grid injection supplies energy for 4,000+ homes

✅ Cuts methane and greenhouse gas emissions significantly

 

In a significant environmental initiative, the Southeastern Chester County Refuse Authority (SECCRA) has partnered with French energy company Waga Energy to convert methane emissions from its landfill into renewable natural gas (RNG). This collaboration aims to reduce greenhouse gas emissions and provide sustainable energy to the local community, echoing energy efficiency projects in Quebec seen elsewhere.

Understanding the Issue

Landfills are a substantial source of methane emissions, accounting for over 14% of human-induced methane emissions, according to the U.S. Environmental Protection Agency. Methane is a potent greenhouse gas, and issues like SF6 in power equipment further boost warming, trapping more heat in the atmosphere than carbon dioxide, making its reduction crucial in the fight against climate change.

The SECCRA-Waga Energy Partnership

SECCRA, serving approximately 105,000 residents in Chester County, processes between 450 to 500 tons of waste daily. To mitigate methane emissions from its landfill, SECCRA has partnered with Waga Energy to install a WAGABOX unit—a technology designed to capture and convert landfill methane into RNG, while related efforts like electrified LNG in B.C. illustrate sector-wide decarbonization.

How the WAGABOX Technology Works

The WAGABOX system utilizes a proprietary process to extract methane from landfill gas, purify it, and inject it into the natural gas grid. This process not only reduces harmful emissions, as emerging carbon dioxide electricity generation concepts also aim to do, but also produces a renewable energy source that can be used to heat homes and power businesses.

Environmental and Community Benefits

By converting methane into RNG, the project significantly lowers greenhouse gas emissions, supported by DOE funding for carbon capture initiatives, contributing to climate change mitigation. Additionally, the RNG produced is expected to supply energy to heat over 4,000 homes, providing a sustainable energy source for the local community.

Broader Implications

This initiative aligns with international clean energy cooperation to reduce methane emissions from landfills. Similar projects have been implemented worldwide, demonstrating the effectiveness of converting landfill methane into renewable energy. For instance, Waga Energy has successfully deployed WAGABOX units at various landfills, showcasing the scalability and impact of this technology.

The collaboration between SECCRA and Waga Energy represents a proactive step toward environmental sustainability and energy innovation. By transforming landfill methane into renewable natural gas, the project not only addresses a significant source of greenhouse gas emissions as new EPA power plant rules on carbon capture advance parallel strategies, but also provides a clean energy alternative for the Chester County community.

UK price cap on household energy bills expected to cost 89bn

UK Energy Price Guarantee Cost forecasts from Cornwall Insight suggest an £89bn bill, tied to wholesale gas prices, OBR projections, and fiscal policy, to shield households amid the cost of living crisis.

 

Key Points

It is the projected government spend to cap household bills, driven by wholesale gas prices and OBR market forecasts.

✅ Base case: £89bn over two years, per Cornwall Insight

✅ Range: £72bn to £140bn, volatile wholesale gas costs

✅ Excludes 6-month business support estimated at £22bn-£48bn

 

Liz Truss’s intervention to freeze energy prices for households for two years is expected to cost the government £89bn, according to the first major costing of the policy by the sector’s leading consultancy.

The analysis from Cornwall Insight, seen exclusively by the Guardian, shows the prime minister’s plan to tackle the cost of living crisis could cost as much as £140bn in a worst-case scenario.

Truss announced in early September that the average annual bill for a typical household would be capped at £2,500 to protect consumers from the intensifying cost of living crisis amid high winter energy costs and a scheduled 80% rise in the cap to £3,549.

The ultimate cost of the policy is uncertain as it is highly dependent on the wholesale cost of gas, including UK natural gas prices which have soared since Russia’s invasion of Ukraine put a squeeze on already-volatile international markets. Ballpark projections had put the cost anywhere from £100bn to £150bn.

The Office for Budget Responsibility is expected to give its forecast for the bill when it provides its independent assessment of Kwasi Kwarteng’s medium-term fiscal plan, which the chancellor said on Tuesday would still happen on 23 November despite previous reports that it would be brought forward.

Cornwall Insight analysed projections of wholesale market moves to cost the intervention. In its base case scenario, analysts expect the policy to cost £89bn. That assumes the cost of supporting each household would be just over £1,000 in the first year, and about £2,000 in the second year.

The study’s authors said the wholesale price of gas would be influenced by energy demand, the severity of weather, “geo-political uncertainty” and prices for liquified natural gas as Europe seeks to refill storage facilities, which countries have rushed to fill up this winter but which could be relatively empty by next spring.

In the best-case outcome, the policy would cost £72bn, with some projections pointing to a 16% decrease in energy bills in April for households, while the “extreme high” outlook would see the government shell out £140bn to protect 29m UK households.

Gas prices are expected to push even higher if the Kremlin decides to completely cut off Russian gas exports into Europe.

Cornwall Insight’s projection does not include a separate six-month initiative to cap costs for companies, charities and public sector organisations, which is forecast to cost £22bn to £48bn.

The consultancy’s chief executive, Gareth Miller, said the £70bn range in its forecasts reflected “a febrile wholesale market continuing to be beset by geopolitical instability, sensitivity to demand, weather and infrastructure resilience”.

He said: “Fortune befriends the bold, but it also favours the prepared. The large uncertainties around commodity markets over the next two years means that the government could get lucky with costs coming out at the low end of the range, but the opposite could also be true.

“In each case, the government may find itself passengers to circumstances outside its control, having made policy that is a hostage to surprises, events and volatile factors. That’s a difficult position to be in.”

The government has faced criticism, as some British MPs urge tighter limits on prices, that the policy is effectively a “blank cheque” and is not targeted at the most vulnerable in society.

Concerns over how Truss and Kwarteng intend to fund a series of measures, including the price guarantee, have spooked financial markets.

The EU, which has outlined possible gas price cap strategies in recent proposals, said last week it planned to cap the revenues of low-carbon electricity generators at €180 a megawatt hour, which is less than half current market prices. Truss has so far resisted calls to extend a levy on North Sea oil and gas operators to electricity generators, who have benefited from a link between gas and electricity prices in Britain.

Truss hopes to strike voluntary long-term deals with generators including Centrica and EDF, alongside the government’s Energy Security Bill measures, to bring down wholesale prices.

The Financial Times reported on Tuesday that the government has threatened companies with legislation to cap their revenues if voluntary deals cannot be agreed.

The Cool Way Scientists Turned Falling Raindrops Into Electricity

Raindrop Triboelectric Energy Harvesting converts falling water into electricity using Teflon (PTFE) on indium tin oxide and an aluminum electrode, forming a transient water bridge; a low frequency nanogenerator for renewable, static electricity harvesting.

 

Key Points

A method using PTFE, ITO, and an aluminum electrode to turn raindrop impacts into low frequency electrical power.

✅ PTFE on ITO boosts charge transfer efficiency.

✅ Water bridge links electrodes for rapid discharge.

✅ Low frequency output suits continuous energy harvesting.

 

Scientists at the City University of Hong Kong have used a Teflon-coated surface and a phenomenon called triboelectricity to generate a charge from raindrops. “Here we develop a device to harvest energy from impinging water droplets by using an architecture that comprises a polytetrafluoroethylene [Teflon] film on an indium tin oxide substrate plus an aluminium electrode,” they explain in their new paper in Nature as a step toward cheap, abundant electricity in the long term.

Triboelectricity itself is an old concept. The word means “friction electricity”—from the Greek tribo, to rub or wear down, which is why a diatribe tires you out—and dates back a long, long time. Static electricity is the most famous kind of triboelectric, and related work has shown electricity from the night sky can be harvested as well in niche setups. In most naturally occurring kinds, scientists have studied triboelectric in order to avoid its effects, like explosions inside of grain silos or hospital workers touching off pure oxygen. (Blowing sand causes an electric field, and NASA even worries about static when astronauts eventually land on Mars.)

One of the most studied forms of intentional and useful triboelectric is in systems such as ocean wave generators where the natural friction of waves meets nanogenerators of triboelectric energy. These even already use Teflon, which has natural conductivity that makes it ideal for this job. But triboelectricity is chaotic, and harnessing it generally involves a bunch of complicated, intersecting variables that can vary with the hourly weather. Promises of static electricity charging devices have often been, well, so much hot, sandy wind.

The scientists at City University of Hong Kong used triboelectric ideas to turn falling raindrops into energy. They say previous versions of the same idea were not very efficient, with materials that didn’t allow for high-fidelity transfer of electrical charge. (Many sources of renewable energy aren’t yet as efficient to turn into power, both because of developing technology and because their renewability means even less efficient use could be better than, for example, fossil fuels, and advances in renewable energy storage could help.)

“[A]chieving a high density of electrical power generation is challenging,” the team explains in its paper. “Traditional hydraulic power generation mainly uses electromagnetic generators that are heavy, bulky, and become inefficient with low water supply.” Diversifying how power is generated by water sources such as oceans and rivers is good for the existing infrastructure as well as new installations.

The research team found that as simulated raindrops fell on their device, the way the water accumulated and spread created a link between their two electrodes, one Teflon-coated and the other aluminum. This watery de facto wire link closes the loop and allows accumulated energy to move through the system. Because it’s a mechanical setup, it’s not limited to salty seawater, and because the medium is already water, its potential isn’t affected by ambient humidity either.

Raindrop energy is very low frequency, which means this tech joins many other existing pushes to harvest continuously available, low frequency natural energy, including underwater 'kites' that exploit steady currents. To make an interface that increases “instantaneous power density by several orders of magnitude over equivalent devices,” as the researchers say they’ve done here, could represent a major step toward feasibility in triboelectric generation.

Six key trends that shaped Europe's electricity markets in 2020

European Electricity Market Trends 2020 highlight decarbonisation, rising renewables, EV adoption, shifting energy mix, COVID-19 impacts, fuel switching, hydro, wind and solar growth, gas price dynamics, and wholesale electricity price increases.

 

Key Points

EU power in 2020 saw lower emissions, more renewables, EV growth, demand shifts, and higher wholesale prices.

✅ Power sector CO2 down 14% on higher renewables, lower coal

✅ Renewables 39% vs fossil 36%; hydro, wind, solar expanded

✅ EV share hit 17%; wholesale prices rose with gas, ETS costs

 

According to the Market Observatory for Energy DG Energy report, the COVID-19 pandemic and favorable weather conditions are the two key drivers of the trends experienced within the European electricity market in 2020. However, the two drivers were exceptional or seasonal.

The key trends within Europe’s electricity market include:


1. Decrease in power sector’s carbon emissions

As a result of the increase in renewables generation and decrease in fossil-fueled power generation in 2020, the power sector was able to reduce its carbon footprint by 14% in 2020. The decrease in the sector’s carbon footprint in 2020 is similar to trends witnessed in 2019 when fuel switching was the main factor behind the decarbonisation trend.

However, most of the drivers in 2020 were exceptional or seasonal (the pandemic, warm winter, high
hydro generation). However, the opposite is expected in 2021, with the first months of 2021 having relatively cold weather, lower wind speeds and higher gas prices, with stunted hydro and nuclear output also cited, developments which suggest that the carbon emissions and intensity of the power sector could rise.

The European Union is targeting to completely decarbonise its power sector by 2050 through the introduction of supporting policies such as the EU Emissions Trading Scheme, the Renewable Energy Directive and legislation addressing air pollutant emissions from industrial installations, with expectations that low-emissions sources will cover most demand growth in the coming years.

According to the European Environment Agency, Europe halved its power sector’s carbon emissions in 2019 from 1990 levels.


2. Changes in energy consumption

EU consumption of electricity fell by -4% as majority of industries did not operate at full level during the first half of 2020. Although majority of EU residents stayed at home, meaning an increase in residential energy use, rising demand by households could not reverse falls in other sectors of the economy.

However, as countries renewed COVID-19 restrictions, energy consumption during the 4th quarter was closer to the “normal levels” than in the first three quarters of 2020. 

The increase in energy consumption in the fourth quarter of 2020 was also partly due to colder temperatures compared to 2019 and signs of surging electricity demand in global markets.


3. Increase in demand for EVs

As the electrification of the transport system intensifies, the demand for electric vehicles increased in 2020 with almost half a million new registrations in the fourth quarter of 2020. This was the highest figure on record and translated into an unprecedented 17% market share, more than two times higher than in China and six times higher than in the United States.

However, the European Environment Agency (EEA)argues that the EV registrations were lower in 2020 compared to 2019. EEA states that in 2019, electric car registrations were close to 550 000 units, having reached 300 000 units in 2018.


4. Changes in the region’s energy mix and increase in renewable energy generation

The structure of the region’s energy mix changed in 2020, according to the report.

Owing to favorable weather conditions, hydro energy generation was very high and Europe was able to expand its portfolio of renewable energy generation such that renewables (39%) exceeded the share of fossil fuels (36%) for the first time ever in the EU energy mix.

Rising renewable generation was greatly assisted by 29 GW of wind and solar capacity additions in 2020, which is comparable to 2019 levels. Despite disrupting the supply chains of wind and solar resulting in project delays, the pandemic did not significantly slow down renewables’ expansion.

In fact, coal and lignite energy generation fell by 22% (-87 TWh) and nuclear output dropped by 11% (-79 TWh). On the other hand, gas energy generation was not significantly impacted owing to favorable prices which intensified coal-to-gas and lignite-to-gas switching, even as renewables crowd out gas in parts of the market.


5. Retirement of coal energy generation intensify

 As the outlook for emission-intensive technologies worsens and carbon prices rise, more and more early coal retirements have been announced. Utilities in Europe are expected to continue transitioning from coal energy generation under efforts to meet stringent carbon emissions reduction targets and as they try to prepare themselves for future business models that they anticipate to be entirely low-carbon reliant.

6. Increase in wholesale electricity prices

In recent months, more expensive emission allowances, along with rising gas prices, have driven up wholesale electricity prices on many European markets to levels last seen at the beginning of 2019. The effect was most pronounced in countries that are dependent on coal and lignite. The wholesale electricity prices dynamic is expected to filter through to retail prices.

The rapid sales growth in the EVs sector was accompanied by expanding charging infrastructure. The number of high-power charging points per 100 km of highways rose from 12 to 20 in 2020.
