What is Hydropower?
Hydroelectric power, one of the cleanest and most sustainable technologies, is a renewable source that harnesses the power of moving water (rivers or reservoirs) to generate electricity. It works by passing water through turbines that convert kinetic energy into mechanical energy and then into electrical energy using a generator. In addition, it allows water flow to be regulated and energy to be stored, contributing to the stability of the electrical system.

Scaling below the surface: Turbine foundations for the next generation of onshore wind
As onshore wind turbines continue to grow taller and more powerful, much of the industry’s focus is on what’s visible above ground – towers, blades and energy output. Less obvious but equally critical are the challenges below the surface, where foundations must carry heavier loads, adapt to complex site conditions,…
