Global Anti-Icing Coating Market Size– Forecasts to 2032: AMR

[reasonsforhope]

"It is 70 years since AT&T’s Bell Labs unveiled a new technology for turning sunlight into power. The phone company hoped it could replace the batteries that run equipment in out-of-the-way places. It also realised that powering devices with light alone showed how science could make the future seem wonderful; hence a press event at which sunshine kept a toy Ferris wheel spinning round and round.

Today solar power is long past the toy phase. Panels now occupy an area around half that of Wales, and this year they will provide the world with about 6% of its electricity—which is almost three times as much electrical energy as America consumed back in 1954. Yet this historic growth is only the second-most-remarkable thing about the rise of solar power. The most remarkable is that it is nowhere near over.

To call solar power’s rise exponential is not hyperbole, but a statement of fact. Installed solar capacity doubles roughly every three years, and so grows ten-fold each decade. Such sustained growth is seldom seen in anything that matters. That makes it hard for people to get their heads round what is going on. When it was a tenth of its current size ten years ago, solar power was still seen as marginal even by experts who knew how fast it had grown. The next ten-fold increase will be equivalent to multiplying the world’s entire fleet of nuclear reactors by eight in less than the time it typically takes to build just a single one of them.

Solar cells will in all likelihood be the single biggest source of electrical power on the planet by the mid 2030s. By the 2040s they may be the largest source not just of electricity but of all energy. On current trends, the all-in cost of the electricity they produce promises to be less than half as expensive as the cheapest available today. This will not stop climate change, but could slow it a lot faster. Much of the world—including Africa, where 600m people still cannot light their homes—will begin to feel energy-rich. That feeling will be a new and transformational one for humankind.

To grasp that this is not some environmentalist fever dream, consider solar economics. As the cumulative production of a manufactured good increases, costs go down. As costs go down, demand goes up. As demand goes up, production increases—and costs go down further. This cannot go on for ever; production, demand or both always become constrained. In earlier energy transitions—from wood to coal, coal to oil or oil to gas—the efficiency of extraction grew, but it was eventually offset by the cost of finding ever more fuel.

As our essay this week explains, solar power faces no such constraint. The resources needed to produce solar cells and plant them on solar farms are silicon-rich sand, sunny places and human ingenuity, all three of which are abundant. Making cells also takes energy, but solar power is fast making that abundant, too. As for demand, it is both huge and elastic—if you make electricity cheaper, people will find uses for it. The result is that, in contrast to earlier energy sources, solar power has routinely become cheaper and will continue to do so.

Other constraints do exist. Given people’s proclivity for living outside daylight hours, solar power needs to be complemented with storage and supplemented by other technologies. Heavy industry and aviation and freight have been hard to electrify. Fortunately, these problems may be solved as batteries and fuels created by electrolysis gradually become cheaper...

The aim should be for the virtuous circle of solar-power production to turn as fast as possible. That is because it offers the prize of cheaper energy. The benefits start with a boost to productivity. Anything that people use energy for today will cost less—and that includes pretty much everything. Then come the things cheap energy will make possible. People who could never afford to will start lighting their houses or driving a car. Cheap energy can purify water, and even desalinate it. It can drive the hungry machinery of artificial intelligence. It can make billions of homes and offices more bearable in summers that will, for decades to come, be getting hotter.

But it is the things that nobody has yet thought of that will be most consequential. In its radical abundance, cheaper energy will free the imagination, setting tiny Ferris wheels of the mind spinning with excitement and new possibilities.

This week marks the summer solstice in the northern hemisphere. The Sun rising to its highest point in the sky will in decades to come shine down on a world where nobody need go without the blessings of electricity and where the access to energy invigorates all those it touches."

1. Pair of rare Amur tiger cubs debuting at Minnesota Zoo are raising hopes for the endangered species

“[The Minnesota Zoo’s] Amur tigers have produced 57 cubs, [… 21 of which] have gone on to produce litters of their own, amounting to another 86 cubs. […] “They’re showing a lot of resiliency, which is something that we work hard for in human care. We want these animals to have a lot of confidence and be able to adapt to new environments just as they’re doing today.””

2. Powered by renewable energy, microbes turn CO₂ into protein and vitamins

“The team designed a two-stage bioreactor system that produces yeast rich in protein and vitamin B9. [… The protein] levels in their yeast exceed those of beef, pork, fish, and lentils. […] Running on clean energy and CO2, the system reduces carbon emissions in food production. It uncouples land use from farming, freeing up space for conservation[… and] will help farmers concentrate on producing vegetables and crops sustainably.”

3. JCPenney Launches Apparel Collection Aimed At Wheelchair Users

“A major department store is rolling out a new line of clothing specifically tailored to meet the needs of women who use wheelchairs featuring options for both everyday wear and special occasions. [… The clothing have] modifications like zippers located for easy access, pocket positioning and extended back rises optimized for the seated position and shorter sleeves to limit interference with wheels.”

4. Snails bred in Edinburgh Zoo sent to re-populate species in French Polynesia

“Thousands of rare partula snails bred at Edinburgh Zoo are to be released in French Polynesia to restore the wild population of the species.The last surviving few of the species were rescued in the early 1990s[….] 15 species and sub-species [are being bred in zoos for repopulation], the majority of which are classed as extinct in the wild.”

5. [NH Joins 19 Other States] to Provide Essential Behavioral Health Services Through Mobile Crisis Intervention Teams

“[CMS] approved New Hampshire’s Medicaid State Plan Amendment for community-based mobile crisis intervention teams to provide services for people experiencing a mental health or substance use disorder crisis. […] The multidisciplinary team provides screening and assessment; stabilization and de-escalation; and coordination with and referrals to health, social, and other services, as needed.”

6. Recovery plan for Missouri population of eastern hellbender

“It is expected that recovery efforts for the Missouri DPS of the eastern hellbender will reduce sedimentation and improve water quality in the aforementioned watersheds, which will also improve drinking water, as well as benefit multiple federally listed mussels, sport fish and other aquatic species.”

7. How $7.3B will help rural co-ops build clean power—and close coal plants

“[The funds are] serving about 5 million households across 23 states [… to] build wind and solar power, which is now cheaper than coal-fired power across most of the country. […] Some of it will be used to pay down the cost of closing coal plants[….] federal funding could help co-ops secure enough wind, solar, and battery resources to retire their entire coal capacity by 2032, cutting carbon emissions by 80 to 90 percent and reducing wholesale electricity costs by 10 to 20 percent[….]”

8. Native-led suicide prevention program focuses on building community strengths

“[Indigenous researchers have] designed programs that aim to build up a community’s endemic strengths, rather than solely treating the risks facing individuals within that community. By providing support and resources that enable access to Alaska Native cultural activities, they hope to strengthen social bonds that build resilience. […] “In a Yup’ik worldview, suicide is not a mental health disorder, and it’s not an individual affliction, it’s a disruption of the collective.””

9. Another rare Javan rhino calf spotted at Indonesia park

“A new Javan rhino calf has been spotted in an Indonesian national park, the facility's head said Friday, further boosting hopes for one of the world's most endangered mammals after two other […] calves were spotted earlier this year at the park, which is the only habitat left for the critically endangered animal.”

10. Transparent solar cells can directly supply energy from glass surfaces

“[Researchers have] unveiled a method of supplying energy directly from glass of buildings, cars, and mobile devices through transparent solar cells. […] It has also succeeded in charging a smartphone using natural sunlight. It also proved the possibility that a screen of a small mobile device can be used as an energy source.”

It's weird how so many people seem to associate crows with the night. I guess because they're black?

Crows sleep through the night, though. In fall and winter you can see them flying off to gather in large roosts just around sunset. I can think of only one encounter I've had with a crow after dark, and that crow was very much dying.

Anyway, the point is that crows are creatures of sunlight. There are a lot of "witchy" crow and moon motifs around, but there should really be more crow and sun.

A collection of hydroponics and solar powered machines I did over the years🌻

There is something about machines that work together with nature, instead against it, that keeps facinating me. I hope to explore this more in the future!

so wait

the green energy parts of the Inflation Reduction Act have brought tons of jobs and money to mostly Republican districts?

and as a result, Republicans will pressure Trump not to gut those aspects of the law?

I am. cackling.

(I mean the man's a loose cannon, so god knows if he'll actually listen. but climate is my biggest worry with this administration, so this gives me a sliver of hope)

(that and him having made Mr. Electric Car Magnate his crony, so he's had to walk back negative statements about those, too)

"Cody Two Bears, a member of the Sioux tribe in North Dakota, founded Indigenized Energy, a native-led energy company with a unique mission — installing solar farms for tribal nations in the United States.

This initiative arises from the historical reliance of Native Americans on the U.S. government for power, a paradigm that is gradually shifting.

The spark for Two Bears' vision ignited during the Standing Rock protests in 2016, where he witnessed the arrest of a fellow protester during efforts to prevent the construction of the Dakota Access Pipeline on sacred tribal land.

Disturbed by the status quo, Two Bears decided to channel his activism into action and create tangible change.

His company, Indigenized Energy, addresses a critical issue faced by many reservations: poverty and lack of access to basic power.

Reservations are among the poorest communities in the country, and in some, like the Navajo Nation, many homes lack electricity.

Even in regions where the land has been exploited for coal and uranium, residents face obstacles to accessing power.

Renewable energy, specifically solar power, is a beacon of hope for tribes seeking to overcome these challenges.

Not only does it present an environmentally sustainable option, but it has become the most cost-effective form of energy globally, thanks in part to incentives like the Inflation Reduction Act of 2022.

Tribal nations can receive tax subsidies of up to 30% for solar and wind farms, along with grants for electrification, climate resiliency, and energy generation.

And Indigenized Energy is not focused solely on installing solar farms — it also emphasizes community empowerment through education and skill development.

In collaboration with organizations like Red Cloud Renewable, efforts are underway to train Indigenous tribal members for jobs in the renewable energy sector.

The program provides free training to individuals, with a focus on solar installation skills.

Graduates, ranging from late teens to late 50s, receive pre-apprenticeship certification, and the organization is planning to launch additional programs to support graduates with career services such as resume building and interview coaching...

The adoption of solar power by Native communities signifies progress toward sustainable development, cultural preservation, and economic self-determination, contributing to a more equitable and environmentally conscious future.

These initiatives are part of a broader movement toward "energy sovereignty," wherein tribes strive to have control over their own power sources.

This movement represents not only an economic opportunity and a source of jobs for these communities but also a means of reclaiming control over their land and resources, signifying a departure from historical exploitation and an embrace of sustainable practices deeply rooted in Indigenous cultures."

1. Agrivoltaics for sustainable food, energy and water management in East Africa

“[… C]ertain crops […] thrived under the partial shade provided by solar panels. The shade also helped to reduce water loss through evaporation, leading to more efficient water usage. Additionally, rainwater harvested from the panels could be used to supplement irrigation needs.”

2. The world’s largest wildlife crossing is now standing in California

“The structure crosses a 10-lane freeway and has been built to help protect all sorts of wildlife[….] And it’s not just for fauna: some 5,000 plants grown from seed collected within a five-mile radius have been nurtured in two specially created nurseries. The bridge will be topped with wildflowers, shrubs and native grasses that will also benefit insect populations.”

3. Judge rules the military must cover gender-affirming surgery for members' dependents

“[Judge] Torresen found that [gender-affirming] surgery is indeed medically necessary and that the Defense Department had not shown that any important governmental interest was advanced by denying the coverage.”

4. Social Media Can Boost Caracal Conservation

“The team found that searches on the species doubled after the project [using “social media to educate about the caracal”] launched. […] ”The research demonstrates how a public interest in urban ecology and the global phenomenon of ‘cats on the internet’… can be harnessed to leverage conservation action.””

5. US Labor Board Bans Captive Audience Meetings to Ensure 'Truly Free' Worker Choice

“[T]he National Labor Relations Board on Wednesday ruled that employers cannot force workers to attend anti-union speeches. [… W]orkers will no longer have to take part in so-called "captive audience meetings," which employers often use as a union-busting tool and a form of coercion.”

6. Study links grazing with plant phenology and abundance

“In general, plants where caribou or muskoxen were present experienced earlier green-up and greater abundance later in the growing season. “We're used to thinking of the timing of plant availability as impacting the productivity of grazing animals, but not the reverse," Post said.”

7. Frog populations once decimated by disease mount a major comeback

“"These results provide a rare example of how reintroduction of resistant individuals can allow the landscape-scale recovery of disease-impacted species, and have broad implications for amphibians and many other taxa that are threatened with extinction by novel pathogens."”

8. California Announces Special Session To Protect Trans People

“Newsom’s directive is clear: safeguard reproductive healthcare, support immigrants, and shield LGBTQ+ people from what is viewed as existential threats to civil rights and democratic norms. […] California has a unique opportunity to set the blueprint for other states in resisting a Trump administration[….]”

9. When ‘OK, Boomer’ Means ‘Let’s Go Protest’

“Youth activists across the country recognize the efforts of their eco-minded predecessors and welcome them as mentors, role models, and collaborators in their battle against the climate crisis. […] “The idea that Boomers don’t care, he said, is “just misinformation.””

10. How Aussie Waste Warriors are Redirecting Excess Food to Those in Need

“A growing movement is working to reduce perfectly good food going to waste by redirecting it to homes and charities. [… C]haritable organisations [… are] transforming fresh produce that would otherwise have gone to waste into millions of cooked, nutritious meals for people in need each year.”
