By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.

Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix. And as a result of competition, this localized form of power is now the country's<a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank" rel="noopener noreferrer"> home-heating market leader.</a></p>
Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

Scaling Up<p>A recent development by E.ON in Hyllie, a district on the outskirts of Malmö, southern Sweden, <a href="https://www.eonenergy.com/blog/2019/February/sweden-smart-city" target="_blank">has scaled up the smart grid principle</a>. Energy generation comes from local wind, solar, biomass and waste sources.</p><p>Smart grids then balance the power, react to the weather, deploying extra power when it's colder or putting excess into battery storage when it's warm. The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>

Only 10% of global energy utility companies are expanding their renewable energy capacity at a faster rate than their gas or coal-fired capacity. That is the main finding of a study by Galina Alova from the Smith School of Enterprise and the Environment at the University of Oxford.
The Matter of Gas<p>The report found that 10% of utilities favored growth in gas-fired power plants, dominated by the US utilities exploiting the country's shale gas reserves, followed by Russia and Germany.</p><p>"Renewables and natural gas often go hand in hand," Alova said, adding that companies often choose both in parallel. "So, it might be just in media reports we are getting this image of investing in renewables, but less coverage on continued investment in gas." </p><p>It might also be the case that gas is viewed as a transition fuel, relatively less carbon emitting and providing load-balancing services to intermittent renewables generation, Alova said.</p><p>Dave Jones, senior electricity analyst for independent climate think tank Ember, agrees with Alova that utilities have hindered the transition by "misunderstanding the future of gas." Utilities have a mindset to build big centralized power plants, replacing a coal power plant with a gas power plant, he said. "Fortunately, most of the gas hype across the world is now dying down, as wind and <a href="https://www.dw.com/en/cheap-solar-energy-prices-explained/a-53590607" target="_blank">solar now provide cheaper options</a> for generating electricity," Jones said.</p>
Green Movement Taking Place<p>Over a fifth of Europe's energy was generated by solar panels and wind turbines in the first half of 2020, according to a report by Ember. Denmark came out on top, generating 64% of its energy from these renewable sources, followed by Ireland (49%) and <a href="https://www.dw.com/en/renewables-make-up-over-half-of-germanys-power-mix/a-52986924" target="_blank">Germany</a> (42%).</p><p>In Ember's half-year review released in July, renewables exceeded fossil fuel generation for the first time ever, producing 40% of the EU's power, with fossil fuels contributing 34%. However, globally only a tenth of all energy was generated by these sources during the first half of 2020. </p><p>Last year saw the use of coal to generate electricity around the world fall by a record 3%. In part due to COVID-19, coal generation in the first half of 2020 again broke records with a drop of 8.3%. In the EU, the drop was higher, as coal energy generation fell by nearly a third.</p>
Slowly Getting There?<p>Utilities have been slow to understand how quickly wind and solar would drop in price, and also how quickly governments would want to move away from coal. "Many utilities have been caught off guard by the speed of the transition, and have suffered financially ever since," said Jones.</p><p>The world this year has generated one-tenth of its electricity from wind and solar, double from the 5% in 2015, and that increase has led to a fall in market share of coal generation, Jones added. </p><p>Valentina Kretzschmar from consultancy Wood Mackenzie says BP's recently announced strategy has created a new industry benchmark. BP plans to increase investment in its low-emission businesses, including renewable energy, by tenfold in the next decade to $5 billion (€4.5 billion) a year, while cutting back oil and gas production by 40%.</p><p>In July, Royal Dutch Shell won a deal to build a wind farm off the coast of the Netherlands, while France's Total has agreed to make several large investments in solar power in Spain and a wind farm off Scotland. Total also bought an electric and natural gas utility in Spain. Shell has said it will <a href="https://www.dw.com/en/mexico-sells-rights-to-19-offshore-oil-fields-for-over-500-million/a-42393559" target="_blank">delay offshore oil fields in the Gulf of Mexico</a> and in the North Sea.</p><p>US giants like Exxon Mobil and Chevron, however, have been slower than their European counterparts to commit to climate goals.</p><p>"I have seen a substantial shift between companies in the fossil fuel clusters toward renewables," Alova said. "This signals that the companies that have been growing fossil fuel portfolios in the earlier time periods might be switching to renewables more recently."</p>
Solar photovoltaic (PV) panels convert sunlight into energy and continue to play an essential role in the fight to stop the climate crisis. As the pioneering panels of the early 2000s near the end of their 30-year electronic lives, however, they are at risk of becoming the world's next big wave of e-waste.

One of the challenges of renewable power is how to store clean energy from the sun, wind and geothermal sources. Now, a new study and advances in nanotechnology have found a method that may relieve the burden on supercapacitor storage. This method turns bricks into batteries, meaning that buildings themselves may one day be used to store and generate power, Science Times reported.
Bricks are a preferred building tool for their durability and resilience against heat and frost since they do not shrink, expand or warp in a way that compromises infrastructure. They are also reusable. What was unknown, until now, is that they can be altered to store electrical energy, according to a new study published in Nature Communications.
The scientists behind the study figured out a way to modify bricks in order to use their iconic red hue, which comes from hematite, an iron oxide, to store enough electricity to power devices, Gizmodo reported. To do that, the researchers filled bricks' pores with a nanofiber made from a conducting plastic that can store an electrical charge.
The first bricks they modified stored enough of a charge to power a small light. They can be charged in just 13 minutes and hold 10,000 charges, but the challenge is getting them to hold a much larger charge, making the technology a distant proposition.
If the capacity can be increased, researchers believe bricks can be used as a cheap alternative to lithium ion batteries — the same batteries used in laptops, phones and tablets.
The first power bricks are only one percent of a lithium-ion battery, but storage capacity can be increased tenfold by adding materials like metal oxides, Julio D'Arcy, a researcher at Washington University in St. Louis, Missouri, who contributed to the paper and was part of the research team, told The Guardian. But only when the storage capacity is scaled up would bricks become commercially viable.
"A solar cell on the roof of your house has to store electricity somewhere and typically we use batteries," D'Arcy told The Guardian. "What we have done is provide a new 'food-for-thought' option, but we're not there yet.
"If [that can happen], this technology is way cheaper than lithium ion batteries," D'Arcy added. "It would be a different world and you would not hear the words 'lithium ion battery' again."

A logged forest is a changed forest, and for woodland caribou that could mean the difference between life and death.
Tar sands mining in Fort McMurray, Alberta fragments habitat for caribou. Kris Krüg / CC BY-NC-ND 2.0<p>But here's the twist: Moose do better in these disturbed landscapes, and that puts caribou further at risk, albeit indirectly.</p><p>Previous research has found that moose prefer the vegetation that grows in these early successional forests that follow a large-scale disturbance, like commercial logging. And a higher density of moose attracts more wolves, which are also able to <a href="https://besjournals.onlinelibrary.wiley.com/doi/full/10.1111/1365-2664.12732" target="_blank">move faster and hunt farther</a> by following linear clearings like roads and pipelines in these developed areas.</p><p>While moose are the primary prey for wolves, caribou that wander into these forests become another tasty target.</p><p>"The bottom line," Fryxell explains, "is that the combination of vegetation changes, increase in road density, increase in moose, and consequent increase in wolves threaten long-term viability of woodland caribou in boreal landscapes of Ontario, in a similar fashion to many other parts of Canada."</p><p>A national assessment found that around 70% of Canada's local <a href="http://registrelep-sararegistry.gc.ca/default.asp?lang=En&n=2FEAAC82-1#_ex" target="_blank">populations of woodland caribou were no longer self-sustaining</a>.</p><p>So what's to be done?</p><p>Last year provincial managers in Quebec floated the idea of <a href="https://www.nationalobserver.com/2019/12/11/news/quebec-plan-kill-wolves-protect-caribou-angers-conservationists" target="_blank">killing wolves</a> to protect caribou herds. Their idea met with public backlash, but wolves in British Columbia weren't so lucky. During the winter of 2019-2020, a whopping 463 wolves were killed by the B.C. provincial government for the stated purpose of protecting populations of southern mountain caribou, another caribou ecotype.</p><p>Some of the money to pay for the kill came from Coastal GasLink, a company actively clearing land in caribou habitat for a pipeline, the Canadian news outlet the <em><a href="https://thenarwhal.ca/a-dangerous-road-coastal-gaslink-pays-to-kill-wolves-in-endangered-caribou-habitat-in-b-c-interior/" target="_blank">Narwhal </a></em><a href="https://thenarwhal.ca/a-dangerous-road-coastal-gaslink-pays-to-kill-wolves-in-endangered-caribou-habitat-in-b-c-interior/" target="_blank">reported</a>.</p><p>And a <a href="https://link.springer.com/article/10.1007/s10531-020-02008-3" target="_blank">recently published study</a> in the journal <em>Biology and Conservation </em>found that the culls were not likely to aid caribou and pointed out several shortcomings in previous research that called for such wolf-control measures.</p><p>There are other, and better, options — like habitat protection and restoration.</p><p>Fryxell's study concluded that "the most secure conservation measure would be to set aside extensive tracts of boreal forest with natural patterns of disturbance to sustain viable caribou sub‐populations."</p><p>Research shows that the animals need at least 65% of their range undisturbed to have a good shot at survival.</p><p>And helping caribou will come with other environmental benefits. Canada's 2018 <a href="http://registrelep-sararegistry.gc.ca/default.asp?lang=En&n=2FEAAC82-1#_ex" target="_blank">federal action</a> plan to restore caribou stated, "Boreal caribou is also considered by many to be an indicator of the overall state of Canada's boreal forest ecosystem."

Investment in U.S. offshore wind projects are set to hit $78 billion (€69 billion) this decade, in contrast with an estimated $82 billion for U.S. offshore oil and gasoline projects, Wood Mackenzie data shows. This would be a remarkable feat only four years after the first offshore wind plant — the 30 megawatt (MW) Block Island Wind Farm off the coast of Rhode Island — started operating in U.S. waters.
Corporates Shift<p>Helping to drive offshore growth, U.S. corporate buyers <a href="https://www.dw.com/en/cities-leading-the-transition-to-renewables/a-42850621" target="_blank">are increasingly relying on wind energy to power their businesses</a>. Walmart and AT&T are the two top corporate wind buyers, while 14 newcomers entered the wind market in 2019, including Estée Lauder and McDonald's.</p><p>"Oil and gas companies have jumped into the U.S. offshore wind market, where they can transfer expertise in offshore fossil fuel development to clean energy investments," says Max Cohen, principal analyst, Americas Power & Renewable research at Wood Mackenzie. Many international oil and gas companies have already recognized this huge potential and entered the US offshore wind market, including Orsted, Equinor and Shell.</p><p>"Given the recent tumult in oil prices, fossil fuel companies may more and more be looking to diversify their portfolios, particularly with assets that are contracted or offer returns uncorrelated with oil and gas," Cohen says. "Offshore wind is an area where they may have a comparative advantage, and they can then leverage the experience with that technology to make the leap to onshore wind, solar, and other renewable technologies," he says.</p>
East Coast leads the way<p>"There is enormous opportunity, especially off the East Coast, for wind. I am very bullish," said former Interior Secretary Ryan Zinke. "Market excitement is moving towards offshore wind. I haven't seen this kind of enthusiasm from industry since the Bakken shale boom," he said.</p><p>Offshore wind initiatives require excessive upfront spending: a 250 MW venture costs about $1 billion, based on International Energy Agency data, but as costs fall the tipping point after which costs fall faster gets nearer</p><p>"The opportunity has been created by Northeastern states seeing the large price declines for offshore wind in Europe," says Cohen. Onshore wind is historically the lowest cost renewable resource, but is at its most expensive in the Northeast, he adds. "But costs are falling slower than for other technologies," he says.</p>
Jobs and Coastal Revitalization<p>U.S. wind energy now supports 120,000 US jobs and 530 domestic factories. A study by the University of Delaware predicted that the supply chain needed to build offshore turbines to feed power to seven East Coast states by 2030 would generate nearly $70 billion in economic activity and at least 40,000 full-time jobs. An American Wind Energy Association's (AWEA's) March 2020 report estimated that developing 30,000 MW of offshore wind along the East Coast could support up to 83,000 jobs and $25 billion in annual economic output by 2030.</p><p>Having said that, not all of the jobs are American jobs. The offshore wind developers with commercial leases in the US are all foreign companies. There is growing interest from the shipbuilding sector in the Gulf of Mexico in partnering with offshore wind companies to provide services. As a result, some of the US oil trade associations have submitted comments supporting certain aspects of offshore wind. "However, it is unclear to what extent offshore wind developers plan to use US vessels and crew, and the existing projects did not incorporate US vessels or labor at all," Hawkins says.</p>

The Bundestag and Bundesrat — Germany's lower and upper houses of parliament — passed legislation on Friday that would phase out coal use in the country in less than two decades as part of a road map to reduce carbon emissions.
Preparing for the Future<p>Coal-producing regions in the German states of North Rhine-Westphalia, Saxony, Saxony-Anhalt and Brandenburg will have access to €40 billion ($45 billion) to help absorb the impact. Those funds are also expected to go towards restructuring regional economies, re-skilling workers and expanding local infrastructure.</p><p>Financial compensation is also be available to coal plant operators who face losses as a result of the early phaseout. However, compensation is contingent on operators announcing plans by 2026 to shutter plants and cease other emissions-intensive activity.</p><p>Michael Vassiliadis, who heads the IG BCE trade union, called the measures a "historic landmark." He said the package has provided a safety net for workers affected by the phase out and would provide them with the necessary support to transition to future sectors.</p>
'Historic Error'<p>However, not everyone agrees that the measures are enough to mitigate climate change.</p><p>Environmentalist activists say the legislation falls short of its ultimate aim, with Greenpeace managing director Martin Kaiser describing it as a "historic error."</p><p>German Green party chief Annalena Baerbock said the legislation was "oblivious to the future" and instead called on the government to complete Germany's coal phase out by 2030 the latest.</p><p>Earlier this year, <a href="https://www.dw.com/en/germans-most-worried-about-refugees-climate-change/a-51947417" target="_blank">a DeutschlandTrend survey</a> found that 27 percent of Germans believe climate change is the most pressing issue facing the country, just slightly behind refugees and immigration policy.</p><p>Germany is seeking to establish a carbon-neutral economy by 2050. The European Commission has also pushed forward with similar plans for the EU.</p>
