Puerto Rico's community-owned solar power: alternative to frequent blackouts
But she is hopeful the lingering hardship will soon be a thing of the past: solar panels are being installed on her home as part of a community program promoting energy independence.
At her house nestled high in the mountains of the lush tropical forests of the archipelago's central city Adjuntas, "it rains a lot and when there's a little wind, the power goes out really quickly," Medina Guzman told AFP.
She has lived in Adjuntas, which has a population of about 20,000, virtually all her life. She said blackouts have always been a feature.
"Sometimes it's at night when it's super hot, and you can't sleep, you can't rest," the 60-year-old said. "It's difficult."
Puerto Rico is a Caribbean territory of more than three million people that has been under US control since 1898.
Its chronic infrastructure woes were exacerbated by 2017's devastating Hurricane Maria, which razed the island's already deteriorating power grid.
After the massive storm, it took roughly 11 months to restore power across the island.
The electrical grid went private in June 2021 in an apparent effort to resolve the problem of perennial blackouts.
But outages persist: this past year, Puerto Rico experienced massive blackouts in April and also on New Year's Eve.
"It's not normal," Medina Guzman said, as a crew installed the battery that will soon store captured energy from the sun.
- 'Hands of the people' -
Like everywhere in Puerto Rico, Adjuntas went dark during Maria -- but in the city's main square, a pink, 1920s-era house was a beacon of light.
It was Casa Pueblo, the nucleus of a grassroots non-profit focused on ecological protection and community support.
It became a haven in the storm's aftermath: the solar panels on its roof meant Casa Pueblo had precious power. People could charge their electronic devices, and crucially plug in medical equipment like oxygen machines.
Cell towers and power lines were down, but Casa Pueblo's community radio station still functioned, becoming a vital source of information in the mountain town.
Casa Pueblo came into being in 1980 -- the brainchild of a citizens group whose original mission was to thwart a series of planned open-pit mines in the region.
They were successful. Over the years, the organization bloomed into a model of bottom-up energy independence, on an island frequently hampered by economic crisis and natural disaster.
"Our aspiration isn't just a technological transition away from fossil fuels to solar. Yes, we need to produce clean and renewable energy, but we are aspiring towards a transformation -- a just, eco-social transition," said Casa Pueblo's director Arturo Massol Deya, a biologist by training.
"That means the energy infrastructure being in the hands of the people," added Massol Deya, whose parents were the group's original founders.
- 'Path to change' -
Among Casa Pueblo's efforts is sustaining a community solar belt that gives vulnerable populations control over their own energy.
The group also has distributed solar lamps and solar refrigerators, especially in rural communities.
Casa Pueblo has so far helped install solar panels on nearly 300 homes, with over 400 projects in total including businesses. Massol Deya told AFP those initiatives are primarily funded through grassroots donations and philanthropy.
Their microgrids -- a localized energy system -- are interconnected and self-sufficient.
And net metering -- a billing mechanism that credits consumers for excess power produced from renewable systems -- allows Casa Pueblo's center to sell back what it doesn't use.
That is particularly meaningful given that average Puerto Ricans pay more than double the price for electricity than mainland US residents, according to US Energy Information Administration data.
"The traditional model is a unilateral, exploitative, monopolistic, dictatorial model," Massol Deya said.
"They decide the price of fuel and whether they give it to you or not. Sometimes they fail and can't provide the service," he said.
"This energy insecurity translates to many issues -- well, not anymore."
Approximately 10 percent of Puerto Rican households currently have solar panels, according to the energy authority, a number that reflects households with net-metering agreements. There is no publicly available data for structures that operate off-grid.
Sergio Rivera Rodriguez is part of a team of academic researchers studying the public health impact of energy security on populations like those in Adjuntas.
He told AFP the Casa Pueblo model could be successful elsewhere.
"I think it's making a difference -- it's of course just one municipality," he said. But "structural changes take years."
Casa Pueblo functions above all, Massol Deya said, because it is a social program that fosters communal control of resources.
"The people are doing it," he said. "This is the path to change."

Extreme Heat Warnings: Here's What To Know About Heat Wave Gripping Much Of U.S.
Millions of Americans are under heat alerts Monday as a heat wave brings triple-digit temperatures or heat indices to nearly half the continental United States, according to the National Weather Service—with the heat expected to impact the parts of the Southeast and the Mississippi river the hardest. Extreme heat warnings were issued for states along the Mississippi River and other parts of the ... More country, and temperatures in New York could reach into the 90s. AFP via Getty Images Extreme heat warnings—the NWS' highest level of heat alert—were issued for several states along the Mississippi River, including southern Illinois and Indiana, western Tennessee and Kentucky, southeastern Missouri, eastern Arkansas, and parts of Louisiana and Mississippi. Similar extreme heat warnings were issued for much of Iowa, Nebraska, South Dakota, as well as parts of Florida, Georgia, South Carolina, North Carolina, Oklahoma, West Virginia, and Ohio. At least 15 more states were placed under heat advisories, the NWS said. Several regions could see the heat index—or what the temperature feels like when combined with humidity—rise well into the triple digits: coastal Georgia and South Carolina could see heat index values rise as high as 115 degrees, New Orleans could rise as high as 114 degrees, and parts of Mississippi and Louisiana could reach heat indices of 120 degrees. Much of the coastal Northeast is also under a heat advisory, with temperatures expected to reach the high 90s or lower 100s in New York City on Monday. Tampa, Florida, broke its all-time heat record Sunday afternoon when the mercury reached the 100 degree mark at Tampa International Airport for the first time ever. The city's previous record was 99 degrees, set in 2020. Forecasters are predicting the temperature to reach the high 90s or low 100s again Monday, with a heat index rising as high as 112 degrees. Leesburg, a city in central Florida north of Orlando, broke its heat record Sunday after reaching 100 degrees as well, and the rest of the region is bracing for more potentially record-breaking triple-digit temperatures Monday and Tuesday. Big Number At least 175 million. That's how many people are under heat advisories, according to an estimate by AccuWeather on Monday. In regions under the extreme heat warnings, the NWS recommends people stay out of the sun and in air conditioning. Limit exercise and "strenuous activity' to mornings and evenings, drink enough fluids, do not leave children or pets in cars, and check up on vulnerable family members and neighbors, the NWS says. Experts also warn Americans to monitor for signs of heat exhaustion—including heavy sweating, clammy skin and fainting. Heat stroke, a more severe condition that occurs after the body reaches an internal temperature above 103 degrees, is a major danger during heat waves, and can cause a rapid pulse, headaches, dizziness, nausea and fainting. When Will The Heat Wave End? Forecasters are predicting much-needed relief for much of the affected areas by the second half of the week, with many of the extreme heat warnings expiring by 8 p.m. on Wednesday or 6 a.m. on Thursday. A cold front will push over a large portion of the country next week, according to forecasters at the Weather Channel, and cooler-than-average temperatures are more likely than extreme heat in much of the Northeast and Midwest in the next 6-10 days, according to the NWS. However, temperatures will still be higher than average for much of south Florida and the Southwest, according to the NWS. Tangent Extreme heat has already disrupted travel, creating adverse conditions for flights and causing problems at the nation's airports. Over 3,900 flights were delayed as of 2 p.m. EDT on Monday, according to online tracker FlightAware. Chicago-O'Hare, Dallas-Fort Worth, and Hartsfield-Jackson Airport in Atlanta had the highest number of delays.

Four killed as heavy rain, flooding soaks northern China
Heavy rains that have soaked swathes of northern China killed four people and left eight missing on Monday, state media said, as downpours force thousands to evacuate across the capital city and surrounding areas. Authorities in Beijing have issued the country's second-highest warning for rainstorms and the highest for floods, with the downpours expected to last into Tuesday morning. In Hebei province, which encircles the capital, the heavy rains caused a landslide in a village near the city of Chengde, state broadcaster CCTV said. Four were killed and eight are still missing, it said, with the national emergency management department dispatching a team to inspect the "severe" flooding in the province, where a further two died over the weekend. Over 4,600 people were evacuated over the weekend in Fuping County, while in neighbouring Shanxi province, one person was rescued and 13 were missing after a bus accident, state media said. Footage from the broadcaster showed roads in the province and a crop field submerged in rushing water on Sunday. In Beijing, over 4,000 people in suburban Miyun district were evacuated due to torrential rains. The area's reservoir "recorded its largest inflow flood" since it was built more than six decades ago, state media reported. On Monday in Mujiayu, a town just south of that reservoir, AFP journalists saw the reservoir release a torrent of water. Power lines had been swept away by muddy currents while military vehicles and ambulances ploughed through flooded streets. A river had burst its banks, sweeping away trees, while fields of crops were inundated with water. Some roads were badly damaged, with chunks of exposed concrete scattered across lanes and twisted guardrails lining their sides. The low-rise houses in the mountainous area, though mostly intact, were surrounded by gushing floods. - Extreme weather - China's National Development and Reform Commission has allocated 50 million yuan ($7 million) to assist relief efforts in Hebei, with the funds going to post-disaster emergency recovery and construction of infrastructure, Xinhua news agency said. Natural disasters are common across China, particularly in the summer when some regions experience heavy rain while others bake in searing heatwaves. China is the world's biggest emitter of the greenhouse gases that scientists say drive climate change and contribute to making extreme weather more frequent and intense. But it is also a global renewable energy powerhouse that aims to make its massive economy carbon-neutral by 2060. Flash floods in eastern China's Shandong province killed two people and left 10 missing this month. A landslide on a highway in Sichuan province this month also killed five people after it swept several cars down a mountainside. bur-mya-isk/oho/jfx

Boats bring Philippine flood victims to safety as death toll rises
Rescuers in the northern Philippines used boats to pick up residents stranded by flooding Friday as Typhoon Co-May was downgraded to a tropical storm and the death toll from a week of monsoon rains edged higher. Schools remained closed and electricity was down in swathes of the archipelago nation's largest island as the national disaster agency reported 25 dead and eight missing since last Friday. But those numbers did not account for three construction workers buried in a landslide as they rested Thursday in Cavite province, south of the capital Manila, according to rescuers. A wall above their construction site collapsed onto the men below after days of rain softened the soil under it, said rescue team member Rosario Jose. "All the bodies were found in the mud," she said. A lone survivor was pulled from the rubble. In the west coast province of La Union, where Typhoon Co-May arrived in the early hours, a family of four was rescued Friday morning after being trapped on the second floor of their wooden home. "They couldn't leave their house because the flood was waist-deep and they have children," said a rescue official who asked not to be named as they were not authorised to speak to media. "Many had been calling us since early morning, but we were having challenges in responding because the rain and winds were so strong," they said, adding that a break in the downpour meant rescue operations were now in full stride. In Bulacan province, just north of Manila, AFP journalists saw entire villages half submerged in floodwaters. Lauro Sabino, 54, said he and his wife had evacuated their home in the morning after a frightening night of hard winds. "It was as if my roof was being blown off. It was creaking. The rain poured the entire night," he said, adding they would sleep at a local market until flooding subsided. "The same thing happens every time. There's no solution," agreed Mary Rose Navia, 25, a housewife whose husband was unable to go to work on Friday. "The floodwaters are just getting deeper." President Ferdinand Marcos on Thursday explicitly tied the recent flooding to climate change, saying his country had to accept this was the "new normal". "This is the way it's going to be as far as we know for... many decades to come, so let's just prepare," he said in a televised cabinet briefing. The storm, which was weakening as it made its way north by northeast, was expected to be gone from the Philippines by Saturday morning. pam-fb/cwl
