Russian buyers are turning to affordable EV models from Chinese automakers, shifting the country's auto market away from traditional internal-combustion vehicles.

Global electricity demand is projected to grow faster than the world economy for the first time, driven largely by the boom in artificial intelligence and data centers. This marks a significant shift, as power consumption historically has grown more slowly than GDP. The trend underscores the increasing energy needs of the tech sector.

Float, an AI energy company, operates with just a three-person team by leveraging Tiger Data's tools for data management and analytics. The small team efficiently handles complex energy data and AI model deployment, demonstrating how streamlined operations and powerful data platforms can enable startups to punch above their weight in capital-intensive industries.

This animated explainer video details how nuclear power plants generate electricity, covering key components from uranium fuel pellets and reactor cores to steam turbines, cooling towers, and safety containment structures.

The article explains that AI's rapid growth is creating a massive demand for electricity, which could become the next major bottleneck for the industry. Data centers consume huge amounts of power, and the existing grid infrastructure may not be able to keep up, potentially slowing AI development and increasing costs.

A study estimates nuclear power prevented 1.84 million air pollution deaths and 64 gigatonnes of CO2 globally from 1971–2009, though the findings rely on assumptions about replacement energy sources.

The author describes managing high-power loads like an electric kettle and toaster on an offgrid system with a small battery, using a relay to prevent the inverter from overloading. However, running a larger load (a heat pump water heater) alongside other devices causes the inverter to trip, leading the author to plan a smarter load management system using an Arduino and relays.

The U.S. federal government agreed to pay Duke Energy $129 million to terminate a wind energy lease off the coast of Brunswick County, North Carolina. The payment settles the cancellation of the lease for a proposed offshore wind project, marking a significant financial resolution between the utility and federal regulators.

The article explains that American data centers face significant delays connecting to the power grid due to slow interconnection processes, regulatory hurdles, and infrastructure bottlenecks, threatening the expansion of AI and cloud computing.

An off-grid cabin uses a generator for big loads like cooking and water pumping, keeping a small 100Ah battery for low-power electronics only, running the generator 30-60 minutes daily instead of investing in a large battery bank.

Japan's unique electrical grid uses two incompatible frequencies—50Hz in the east and 60Hz in the west—due to late 19th-century adoption of different foreign generators. This technical divide, rooted in historical decisions by Tokyo's and Osaka's early power companies, persists today and adds costs, complexity, and fragility to Japan's power system.

Antares Industries has achieved criticality of its Mark-0 reactor, marking a key milestone in the development of its nuclear propulsion technology for space applications. The company announced the successful first criticality event, confirming the reactor's ability to sustain a controlled nuclear chain reaction.

Oil inventories in the U.S. Strategic Petroleum Reserve fell by 5.5 million barrels, dropping to the lowest level since 1983, according to recent data.

The article provides a beginner's guide to the strategic and logistical challenges involved in reopening the Strait of Hormuz, a critical maritime chokepoint for global oil and gas shipments. It outlines the geopolitical tensions, potential disruptions, and the complex naval and diplomatic efforts required to restore safe passage through the strait.

Safety concerns are rising as the U.S. plans new nuclear reactors for the America 250 initiative. Experts and communities warn of unresolved issues around waste, accident risks, and oversight. Federal agencies are working to address these challenges before approving new projects.

A new analysis warns that US grid constraints could force up to 40GW of behind-the-meter datacenter capacity by 2028, driven by AI power demand and interconnection delays. This shift may bypass traditional utility oversight, raising reliability and cost concerns for residential ratepayers.

The head of a major US utility has warned that the country faces an increased risk of blackouts, as power supply struggles to keep pace with surging demand from data centers, electric vehicles, and manufacturing. The shortfall is exacerbated by the retirement of coal and natural gas plants faster than new generation sources are being built.

Only about 20% of European households have air conditioning, compared to over 90% in the US. Climate change is boosting demand, but high costs and inadequate building infrastructure limit adoption across the continent.

The article examines why new data centers in the US face long delays connecting to the electric grid, citing broken interconnection processes, regional grid constraints, and regulatory bottlenecks that hinder the rapid deployment of power-hungry AI and cloud computing infrastructure.

A Physics Stack Exchange discussion explains that kinetic energy increases with the square of speed (KE = ½mv²) rather than linearly because work required to accelerate an object depends on both force and distance, and at higher speeds, the distance over which force is applied increases, leading to a quadratic relationship.

The article examines why new data centers in the US face years-long delays connecting to the electric grid due to a combination of outdated interconnection rules, utility monopolies, and a fragmented approval process. It argues that the current system, designed for a different era of energy demand, is unable to keep pace with the rapid expansion needed for AI and cloud computing.

Iraq has warned it may consider leaving OPEC if its oil production quota is not raised, according to sources familiar with the matter. Baghdad is exploring all options, including a potential exit, as it seeks a higher output limit to boost revenues.

China's coal-fired power generation is projected to increase in 2026, reversing the first decline in a decade seen the previous year. The rebound is driven by rising electricity demand and a slowdown in renewable energy capacity additions, highlighting the continued reliance on coal for energy security.

A severe heat wave in Europe is straining the power grid as demand for cooling surges while certain power plants reduce output due to high temperatures. The article examines the risks of blackouts and the challenges for renewable energy sources, emphasizing the need for grid resilience amid increasingly frequent extreme weather events linked to climate change.

Nick Carr explores the decommissioned Shoreham Nuclear Power Plant on Long Island, a facility completed but never commercially operated. The plant is being dismantled, with its reactor removed and the site undergoing environmental cleanup.

The Economist argues that as Europe faces more intense heatwaves, widespread adoption of air-conditioning is inevitable and beneficial if powered by green electricity. Rather than resisting AC, Europeans should embrace it while accelerating the shift to renewable energy sources, making cooling sustainable without compromising climate goals.

The U.S. Department of Energy announced $17.5 billion in conditional loan guarantees aimed at bolstering the domestic nuclear power supply chain, including support for uranium enrichment, fuel fabrication, and advanced reactor development. The funding is part of broader federal efforts to maintain existing reactors and expand nuclear capacity to meet clean energy targets.

The U.S. government announced $17.5 billion in conditional loan guarantees aimed at strengthening the domestic nuclear power supply chain. The funding is intended to support uranium enrichment, fuel fabrication, and reactor component manufacturing to boost nuclear energy capacity.
