As the demand for artificial intelligence (AI) surges, Big Tech companies are grappling with the challenge of powering data centers without exacerbating climate change. Despite commitments to sustainability, the rapid growth of AI is pushing these firms to reconsider their energy sources, balancing between renewable energy advancements and the immediate availability of fossil fuels. This tension highlights the broader implications of AI's energy consumption on global environmental goals.

The global shortage of Graphics Processing Units (GPUs) has significantly impacted various industries, from gaming to high-performance computing. Initially triggered by the COVID-19 pandemic, this crisis was exacerbated by increased demand for cryptocurrency mining and supply chain disruptions. As manufacturers struggle to meet the soaring demand, the shortage has led to inflated prices and limited availability, affecting consumers and enterprises alike.

As artificial intelligence (AI) applications become increasingly complex, the demand for specialized hardware capable of efficiently processing AI workloads has surged. Graphics Processing Units (GPUs), Tensor Processing Units (TPUs), and Neural Processing Units (NPUs) each play distinct roles in the ecosystem of AI hardware, offering varying capabilities and optimizations tailored to different aspects of AI processing. This introduction explores the fundamental differences and specific...

Electrocaloric cooling is emerging as a promising alternative to conventional refrigeration technologies, offering an environmentally friendly and potentially more efficient approach to temperature regulation. Based on reports from Science and Nature, this innovative cooling method harnesses the electrocaloric effect in certain materials, primarily ferroelectrics, which undergo reversible temperature changes when exposed to electric fields.
