“The AI-driven, energy-hungry data-center boom was bound to bring up uncomfortable questions: Will it raise energy bills and, if so, who will shoulder the costs? America’s largest wholesale power market is starting to see the results. Rapid data-center build-out is increasing power demand just as a wave of older power-plant retirements is reducing supply in PJM Interconnection, the independent system operator that manages the wholesale power market spanning 13 states including Virginia, Pennsylvania and Illinois. It said two weeks ago that its latest capacity auction yielded prices of $269.92 per megawatt-day for most of its footprint, about nine times the clearing price a year ago. A contributing factor was a tweak in PJM’s modeling to better plan for extreme weather conditions. Skyrocketing capacity prices are a clear signal that the grid needs new power plants.”

“Ukraine will need $20 billion in investments to develop its renewable power sector under a plan which seeks to boost its share in the country’s energy mix to 27% by 2030, the government said on Tuesday. The country’s energy sector has lost half of its generating capacity as a result of Russian missile and drone attacks, which intensified in spring 2024, forcing it to rely on its nuclear plants as well as solar and wind generation.”

“Tropical Storm Ernesto threatens to trigger floods and landslides across Puerto Rico and will test the island’s electric grid, which has been battered by storms in recent years. Ernesto, the fifth Atlantic storm this year, had top winds of 45 miles (72 kilometers) per hour as it crossed the Leeward Islands 35 miles northwest of Guadeloupe, the National Hurricane Center said in an advisory at 8 a.m. New York time. While the storm’s winds will continue to intensify as it moves toward Puerto Rico later Tuesday, flooding is the bigger concern.”

“More than 47,000 Europeans died from heat-related causes during 2023, the world’s hottest year on record, a new report in Nature Medicine has found. But the number could have been much higher. Without heat adaptation measures over the past two decades, the death toll for Europeans experiencing the same temperatures at the start of the 21st century could have been 80 percent higher, according to the new study. For people over 80 years old, the toll could have doubled.”

“With the shift towards low-carbon economies, energy security has emerged as an increasingly vital concern for governments worldwide, particularly in recent years, because of ongoing conflicts and increased volatility in the international energy market. Both laws and policies are essential tools for mitigating climate change challenges; however, its role in energy security remains unexplored. Drawing on climate-related legislative activities in 127 countries from 2000 to 2021, this study examines the short- and long-term impact of climate laws and policies on energy security performance (ESP). The empirical results demonstrate that both recent and longstanding climate laws and policies have enhanced the national ESP on a global scale. Furthermore, we find that laws outperform policies regarding energy security improvement. Additional analyses indicate that the impact of climate laws and policies on ESP is more effective across high- and upper-middle-income countries, and less effective in low-income countries, especially those in Africa. Our findings highlight the significance of climate legislative efforts and provide important implications for global governments in securing their green transition.”
