They will die together one day in one another's arms 😊🫂💞

[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. All 160 dogs at Florida shelter found homes ahead of Hurricane Milton

“[The shelter] offered crates, food and anything else the dogs would need in exchange for the animals to spend just five days with the foster parents if the human didn't want to keep them for longer. […A]fter about a day of receiving around 100 messages every 30 minutes, Bada said, all 160 were gone from the shelter and in safe and warm homes.”

2. Restoring Ecosystems and Rejuvenating Native Hawaiian Traditions in Maui

“[Volunteers] are restoring water flow to the refuge, removing invasive species, and restoring a loko iʻa kalo using ʻike kūpuna, ancestral knowledge. […] This human-made ecosystem will provide food for community members and habitat for wildlife while protecting coral reefs offshore.”

3. Solar-powered desalination system requires no extra batteries

“In contrast to other solar-driven desalination designs, the MIT system requires no extra batteries for energy storage, nor a supplemental power supply, such as from the grid. […] The system harnessed on average over 94 percent of the electrical energy generated from the system’s solar panels to produce up to 5,000 liters of water per day[….]”

4. Threatened pink sea fan coral breeds in UK aquarium for first time

“The spawning is part of University of Exeter Ph.D. student Kaila Wheatley Kornblum's research into the reproduction, larval dispersal and population connectivity of Eunicella verrucosa. […] Pink sea fans are believed to have been successfully bred by only one other institution, Lisbon Oceanarium, in 2023.”

5. Tiny 'backpacks' are being strapped to baby turtles[….]

““We analysed the data and found that hatchlings show amazingly consistent head-up orientation – despite being in the complete dark, surrounded by sand [… and] they move as if they were swimming rather than digging[…. This new observation method is] answering questions about best conservation practices,” says Dor.”

6. New California Law Protects Wildlife Connectivity

“A new state law in California will instruct counties and municipalities to conserve wildlife corridors when planning new development. […] This could entail everything from creating wildlife crossings at roads or highways, employing wildlife-safe fencing, or not developing on certain land.”

7. ‘I think, boy, I’m a part of all this’: how local heroes reforested Rio’s green heart

“By 2019, [the program] had transformed the city’s landscape, having trained 15,000 local workers like Leleco, who have planted 10m seedlings across […] roughly 10 times the area of New York’s Central Park. Reforested sites include mangroves and vegetation-covered sandbars called restinga, as well as wooded mountainsides around favelas.”

8. Alabama Town Plans to Drop Criminal Charges Over Unpaid Garbage Bills

““Suspending garbage pickup, imposing harsh late penalties and prosecuting people who through no fault of their own are unable to pay their garbage and sewage bills does not make payment suddenly forthcoming,” West said. [… The city] has agreed to drop pending criminal charges against its residents over unpaid garbage bills.”

9. New Hampshire’s low-income community solar program finally moves forward

“The state energy department is reviewing seven proposals for community solar arrays that will allocate a portion of their bill credits to low-income households. […] New Hampshire’s strategy of working with utilities to automatically enroll households that have already been identified streamlines the process.”

10. The Future Looks Bright for Electric School Buses

“EPA has awarded about $3 billion in grants from the infrastructure law, which paid to replace about 8,700 buses. Of those, about 95 percent are electric. [… Electric buses are] cheaper to operate and require less maintenance than diesel buses and will soon be at cost parity when looking at the lifetime cost of ownership[….]”

African poverty is partly a consequence of energy poverty. In every other continent the vast majority of people have access to electricity. In Africa 600m people, 43% of the total, cannot readily light their homes or charge their phones. And those who nominally have grid electricity find it as reliable as a Scottish summer. More than three-quarters of African firms experience outages; two-fifths say electricity is the main constraint on their business.

If other sub-Saharan African countries had enjoyed power as reliable as South Africa’s from 1995 to 2007, then the continent’s rate of real GDP growth per person would have been two percentage points higher, more than doubling the actual rate, according to one academic paper. Since then South Africa has also had erratic electricity. So-called “load-shedding” is probably the main reason why the economy has shrunk in four of the past eight quarters.

Solar power is increasingly seen as the solution. Last year Africa installed a record amount of photovoltaic (PV) capacity (though this still made up just 1% of the total added worldwide), notes the African Solar Industry Association (AFSIA), a trade group. Globally most solar PV is built by utilities, but in Africa 65% of new capacity over the past two years has come from large firms contracting directly with developers. These deals are part of a decentralised revolution that could be of huge benefit to African economies.

Ground zero for the revolution is South Africa. Last year saw a record number of blackouts imposed by Eskom, the state-run utility, whose dysfunctional coal-fired power stations regularly break down or operate at far below capacity. Fortunately, as load-shedding was peaking, the costs of solar systems were plummeting.

Between 2019 and 2023 the cost of panels fell by 15%, having already declined by almost 90% in the 2010s. Meanwhile battery storage systems now cost about half as much as five years ago. Industrial users pay 20-40% less per unit when buying electricity from private project developers than on the cheapest Eskom tariff.

In the past two calendar years the amount of solar capacity in South Africa rose from 2.8GW to 7.8GW, notes AFSIA, excluding that installed on the roofs of suburban homes. All together South Africa’s solar capacity could now be almost a fifth of that of Eskom’s coal-fired power stations (albeit those still have a higher “capacity factor”, or ability to produce electricity around the clock). The growth of solar is a key reason why there has been less load-shedding in 2024...

Over the past decade the number of startups providing “distributed renewable energy” (DRE) has grown at a clip. Industry estimates suggest that more than 400m Africans get electricity from solar home systems and that more than ten times as many “mini-grids”, most of which use solar, were built in 2016-20 than in the preceding five years. In Kenya DRE firms employ more than six times as many people as the largest utility. In Nigeria they have created almost as many jobs as the oil and gas industry.

“The future is an extremely distributed system to an extent that people haven’t fully grasped,” argues Matthew Tilleard of CrossBoundary Group, a firm whose customers range from large businesses to hitherto unconnected consumers. “It’s going to happen here in Africa first and most consequentially.”

Ignite, which operates in nine African countries, has products that include a basic panel that powers three light bulbs and a phone charger, as well as solar-powered irrigation pumps, stoves and internet routers, and industrial systems. Customers use mobile money to “unlock” a pay-as-you-go meter.

Yariv Cohen, Ignite’s CEO, reckons that the typical $3 per month spent by consumers is less than what they previously paid for kerosene and at phone-charging kiosks. He describes how farmers are more productive because they do not have to get home before dark and children are getting better test scores because they study under bulbs. One family in Rwanda used to keep their two cows in their house because they feared rustlers might come in the dark; now the cattle snooze al fresco under an outside lamp and the family gets more sleep.

...That is one eye-catching aspect of Africa’s solar revolution. But most of the continent is undergoing a more subtle—and significant—experiment in decentralised, commercially driven solar power. It is a trend that could both transform African economies and offer lessons to the rest of the world."

1. Wyoming's abortion ban has been overturned, including its ban on abortion medication

“Wyoming is the second state to have its near-total abortion ban overturned this month[…. Seven other states] also approved amendments protecting the right to an abortion. A lawsuit seeking to challenge the [FDA]’s approval of abortion medication recently failed when the Supreme Court refused to hear it[….]”

2. Patches of wildflowers in cities can be just as good for insects as natural meadows – study

“This study confirmed that small areas of urban wildflowers have a high concentration of pollinating insects, and are as valuable to many pollinators as larger areas of natural meadow that you would typically find rurally.”

3. Paris could offer new parents anti-pollution baby 'gift bags' to combat 'forever chemicals'

“The bag includes a stainless steel baby cup, a wooden toy, reusable cotton wipes, and non-toxic cleaning supplies as part of a "green prescription". […] The city will also have 44 centres for protecting mothers and infants that will be without any pollutants[….]”

4. Indigenous guardians embark on a sacred pact to protect the lowland tapir in Colombia

“The tapir is now the focus of an Indigenous-led conservation project[… A proposed “biocultural corridor”] will protect not only the populations and movements of wildlife such as tapirs, but also the cultural traditions and spirituality of the Inga and other neighboring Indigenous peoples[….]”

5. Denmark will plant 1 billion trees and convert 10% of farmland into forest

“[…] 43 billion kroner ($6.1 billion) have been earmarked to acquire land from farmers over the next two decades[.… In addition,] livestock farmers will be taxed for the greenhouse gases emitted by their cows, sheep and pigs from 2030, the first country to do so[….]”

6. The biggest grid storage project using old batteries is online in Texas

“[Element operates “used EV battery packs” with software that can] fine-tune commands at the cell level, instead of treating all the batteries as a monolithic whole. This enables the system to get more use out of each cell without stressing any so much that they break down[….]””

7. Durable supramolecular plastic is fully ocean-degradable and doesn't generate microplastics

“The new material is as strong as conventional plastics and biodegradable, [… and] is therefore expected to help reduce harmful microplastic pollution that accumulates in oceans and soil and eventually enters the food chain.”

8. Big Oil Tax Could Boost Global Loss and Damage Fund by 2000%

“[… A] tax on fossil fuel extraction, which would increase each year, combined with additional taxes on excess profits would […] generate hundreds of billions of dollars by the end of the decade to assist poor and vulnerable communities with the impact of the climate crisis[….]”

9. Rooftop solar meets 107.5 pct of South Australia’s demand, no emergency measures needed

“[T]he state was able to export around 658 MW of capacity to Victoria at the time[….] The export capacity is expected to increase significantly as the new transmission link to NSW[…] should be able to allow an extra 150 MW to be transferred in either direction by Christmas.”

10. Light-altering paint for greenhouses could help lengthen the fruit growing season in less sunny countries

“[Scientists] have developed a spray coating for greenhouses that could help UK farmers to produce more crops in the future using the same or less energy[… by optimising] the wavelength of light shining onto the plants, improving their growth and yield.”
