Amazon will buy a new type of HVAC system for its commercial buildings to slash energy use.

The startup has put a spin on repurposing EV batteries, CEO Edward Chiang told TechCrunch.

Energy costs continue to rise, while sustainability regulations become stricter each year. What used to be considered advanced building technology is now turning into a baseline requirement. Smart buildings are no longer a differentiator — they are an expectation.

Overview Electric powertrain systems face complex design, testing, and integration challenges in both aviation and space applications due to increased power levels operating at higher altitudes. Components such as batteries require high energy density and increased reliability in order to operate safely under extreme conditions and be certified for flight. D-Site offers a unique environment for i…

IntroductionHydro-dominant power systems in Latin America are recurrently exposed to ENSO-driven hydrological scarcity, creating adequacy risks precisely when firm energy is most valuable.MethodsThis paper proposes a Monte Carlo-based methodology to accredit nuclear firm energy for small modular reactors (SMRs) under climatic stress, using an explicit stress-month definition derived from long-run…

As photovoltaic (PV) power plants expand, UAV-based infrared thermography has become a standard tool for efficient and safe fault diagnosis. However, most deep learning models are too large and computationally heavy for real-time deployment on edge devices. We propose NanoDistillNet, a lightweight model based on knowledge distillation designed for on-board processing. The framework utilizes a tea…

Capacity planning in highway multi-energy systems faces significant challenges due to the high uncertainty of renewable energy generation and the limited availability of historical data during the planning stage. This paper proposes an integrated framework that combines photovoltaic (PV) scenario generation using a Conditional Variational Autoencoder (CVAE) with a Wasserstein-type distributionall…

To fully and effectively exploit the spatiotemporal correlations among multi-user loads, this paper proposes an online short-term multi-user load forecasting method based on dynamic recognition of spatiotemporal dependencies. A hybrid graph convolutional network-bidirectional long short-term memory (GCN-BiLSTM) model is employed to capture the complex spatiotemporal relationships among multi-user…

This article studies the load frequency control (LFC) problem of multi-area interconnected power systems under the threat of denial-of-service (DoS) attacks. Due to the open communication network of control regions, interconnected power systems are particularly vulnerable to Dos attacks, which can undermine the stable operation of the power system. To deal with this problem, we design a novel sel…

China’s power industry faces critical challenges in balancing rapid economic growth with environmental sustainability amidst surging electricity demand from artificial intelligence (AI), cloud computing, and data centers. This study introduces the Data Center Energy Consumption Ratio (DCECR) as a quantitative metric and comprehensively evaluates China’s “East-to-West Computing” (ETWC) strategy th…

IntroductionDriven by the global energy transition and the “Dual-Carbon” strategy, the electrification of heavy-duty logistics has introduced massive mobile energy storage resources Electric Trucks (ETs) into dairy industrial park (DIP). However, the random charging/discharging behaviors of ETs, coupled with multi-energy flow coupling and conflicting stakeholder interests, exacerbate system peak–…

To address the challenges of voltage deviation and increased network losses arising from the high integration of photovoltaic (PV) systems in distribution networks, this paper proposes a bi-level optimisation model for configuring distributed energy storage systems (ESS) tailored to high-penetration PV distribution networks. In the proposed model, the upper-level operational layer minimises volta…

President Donald Trump may soon feel the need to "blockade" U. S. crude oil exports after those exports hit a record high recently, a trend which, if it continues, will increase the price U. S. consumers pay for gasoline, diesel a...

For this system to achieve total economic viability, it must be viewed as a dual-function apparatus: a high-energy pulse harvester (lightning) and a continuous low-energy ionic co lector (atmospheric energy). ( direct link )

Every day, huge amounts of energy are wasted as heat. Cars release heat through their exhaust, factories lose heat during production, and even our own bodies give off warmth. Scientists have long wanted to capture this lost energy and turn it into electricity. Now, a new study shows that computers may hold the key to […] The post Strange new shape boosts energy conversion by over 8 times appeared…

China’s power grid is facing several challenges to reliability. While demand continues to grow, new resources are coming online, which change previous patterns. China’s Southern Grid has a particularly unique situation, given its largest consuming province, Guangdong, is reliant on imported hydropower, which can face transmission constraints as well as low rainfall. Offshore wind has the potentia…

Vacuum technology keeps running into sustainability challenges. First there was a helium shortage. Then another. And another. In addition, the industry has been moving away from oil-sealed pumps and towards more sustainable methods.  Helium shortages affect lab equipment Helium shortages aren’t exactly new. The gas has been through four supply crunches since 2006, each driven… The post Helium sho…

A new technical paper, “Highly energy-efficient manifold microchannel for cooling electronics with a coefficient of performance over 100,000,” was published by researchers at KAIST. The study presents a CMOS-compatible manifold microchannel cooler that removes over 2,000 W/cm² using single-phase water at only 8 kPa pressure drop, achieving a record COP of 106,000—a significant improvement over...…
