Coal has dominated fuel choices in Asia since 2010, even in gas-centric Southeast Asian countries, and many forecasts assume that coal will remain the region’s most economical option. But lower natural gas prices and individual market conditions are putting a dent in coal’s future in the region, some experts note. According to Graham Tyler, Wood […]

The life of a wind turbine can be pretty precarious. The blades—made of laminated materials, such as composites, balsa wood, carbon fiber, and fiberglass—can reach speeds up to 180 miles per hour at the tip, which means even small particles in the air can cause damage to the surfaces. It’s probably no surprise that lightning […]
