How Sweden Is Transforming Homes Into Power Stations
By Harry Kretchmer
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.
As well as targeting 100% renewable electricity production by 2040, the country is transforming homes into highly efficient 'prosumers' - buildings which both produce and consume the vast majority of their own energy.
Meanwhile local 'district heating' plants are using excess heat to produce over 75% of the warmth that Swedish households need. The country also manages to combine the world's highest carbon taxes with relatively cheap energy prices.
These are all reasons why Sweden tops the Forum's Energy Transition Index - providing environmental leadership at a time when a Great Reset has never been more needed. Here's how Sweden is building up local solutions in its energy revolution.

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 two largest renewable power sources are hydropower and biomass. And that biomass is helping support a local energy boom.
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.
In Sweden these trace their origins back to 1948, when a power station's excess heat was first used to heat nearby buildings: steam is forced along a network of pipes 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.
District heating used to be fueled mainly from the by-products of power plants, 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 home-heating market leader.

But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.
One example is in the city of Ludivika where 1970s flats have recently been retrofitted with the latest smart energy technology.
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.
The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With high levels of smart meter usage, it's a model that looks set to spread across Sweden.

A recent development by E.ON in Hyllie, a district on the outskirts of Malmö, southern Sweden, has scaled up the smart grid principle. Energy generation comes from local wind, solar, biomass and waste sources.
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.
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.
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.

Trump Calls Fauci 'a Disaster,' Tries to Blame Science and Medical Experts for Failed Coronavirus Response
President Trump attacked the nation's top infectious disease specialist in a call with campaign staffers that several reporters were allowed to listen to on Monday. In the call, Trump said that Dr. Anthony S. Fauci was "a disaster." He added that despite the evidence that coronavirus cases are once again rising across the country, the public was tired of hearing so much news about the virus, especially from "these idiots" in the government and scientific community, as The Washington Post reported.

Colorado voters will decide on Nov. 3 whether the state should reintroduce gray wolves (Canis lupus) after a nearly 80-year absence. Ballot Proposition 114 would require the state to develop and oversee a science-based plan to restore wolves, focused in Western Colorado and initiated by the end of 2023.

Clashing Values<p>Proposition 114 has strong support in Colorado. <a href="https://extension.colostate.edu/topic-areas/people-predators/public-perspectives-on-wolves-and-wolf-reintroduction-8-004/" target="_blank">Statewide surveys </a> conducted by phone, by mail and online over the past two decades have found that 66% to 84% of respondents supported reintroducing wolves. This support is consistent across different regions of the state and diverse demographic groups.</p><p>In a <a href="https://doi.org/10.7717/peerj.9074" target="_blank">survey of Colorado residents</a> that we conducted in 2019, the prospect that wolves could contribute to a balanced ecosystem was the most commonly cited reason for supporting reintroduction. Other arguments included people's cultural and emotional connections to wolves, and <a href="https://extension.colostate.edu/topic-areas/people-predators/moral-arguments-related-to-wolf-restoration-and-management-8-011/" target="_blank" rel="noopener noreferrer">moral arguments</a> that restoring a species humans had eradicated was the right thing to do.</p><p>While overall public support is strong, over half of Colorado's 64 counties have passed <a href="https://www.drovers.com/article/wolf-reintroduction-ballot-colorado" target="_blank" rel="noopener noreferrer">resolutions against restoring wolves</a>. Many ranching and hunting associations are actively campaigning against the ballot measure.</p><p>In our 2019 study, we found that media coverage in the state focused more strongly on <a href="https://doi.org/10.7717/peerj.9074" target="_blank" rel="noopener noreferrer">perceived negative impacts</a> associated with wolf reintroduction than on beneficial effects. Surveys show that resident concerns include threats to <a href="https://extension.colostate.edu/topic-areas/people-predators/wolves-and-human-safety-8-003/" target="_blank" rel="noopener noreferrer">human safety and pets</a>; <a href="https://extension.colostate.edu/topic-areas/people-predators/wolves-and-livestock-8-010/" target="_blank" rel="noopener noreferrer">wolf attacks on livestock</a>; and the potential for wolves to <a href="https://extension.colostate.edu/topic-areas/people-predators/wolves-big-game-and-hunting-8-001/" target="_blank" rel="noopener noreferrer">reduce deer and elk populations</a>, threatening hunting opportunities.</p>
Who Decides?<p>This measure is the first giving voters in the U.S. an opportunity to weigh in on bringing back a native species. Addressing the issue through a ballot measure adds a unique twist to public and media discussions about wolves.</p><p>Supporters call it a democratic way to ensure that the <a href="https://www.cpr.org/2020/09/29/should-wolves-be-brought-back-to-colorado-a-rancher-and-a-biologist-have-their-say/" target="_blank">public's values are recognized</a>.

Finding Consensus<p>Studies suggest that ballot initiatives like 114 will <a href="https://doi.org/10.1016/j.biocon.2017.07.032" target="_blank">become more common</a> as public values toward wildlife change and more diverse groups seek to influence wildlife management.

Fostering dialogue between groups that value wildlife differently can build empathy and mutual understanding and <a href="https://doi.org/10.1016/j.biocon.2014.07.015" target="_blank" rel="noopener noreferrer">foster compromise</a>. Broadening the conversation in this way is essential for coexisting with carnivores with minimal impacts on predators and people.</p>

Fish exposed to endocrine-disrupting compounds pass on health problems to future generations, including deformities, reduced survival, and reproductive problems, according to a new study.
Low Levels Lead to Generational Impacts<p>Researchers exposed inland silverside fish to bifenthrin, levonorgestrel, ethinylestradiol, and trenbolone to levels currently found in waterways.</p><p>"Our concentrations were actually on the low end" of what is found in the wild, DeCourten said, adding that it was low amounts of chemicals in parts per trillion.</p><p>Bifenthrin is a pesticide; levonorgestrel and ethinylestradiol are synthetic hormones used in birth controls; and trenbolone is a synthetic steroid often given to cattle to bulk them up.</p><p>Such endocrine-disruptors have already been linked to a variety of health problems in directly exposed fish including altered growth, reduced survival, lowered egg production, skewed sex ratios, and negative impacts to immune systems. But what remains less clear is how the exposure may impact future generations.</p><p>For their study, DeCourten and colleagues started the exposure when the fish were embryos and continued it for 21 days.</p><p>They then tracked effects on the exposed fish, and the next two generations.</p>
Inherited Problems<p>DeCourten said the altered DNA methylation is one of the plausible ways that future generations would experience health impacts from previous generations' exposure. Hormone-disrupting compounds have been shown to impact DNA methylation, which is an important marker of how an organism will develop.</p><p>"Methyl groups are added to specific sites on the genome, [the exposure] is not changing the genome itself, but rather how the genome is expressed," she said. "And that can be inherited throughout generations."</p><p>In addition, Brander said there are essentially different "tags" that exist on DNA molecules, which tell genes how to turn on and off. She said the exposure to different compounds may be "influencing which methyl tags get taken on or off as you proceed through generations."</p><p>The researchers said the study should prompt future toxics testing to consider impacts on future generations.</p><p>"The results … throw a wrench in the current approach to regulating chemicals, where it's often short-term testing looking at simple things like growth, survival, and maybe gene expression," Brander said.</p><p>"These findings are telling us we really at least need to consider" the next two generations, she added.</p>
