The Sustainability of Energy and the Role of Geophysics
Introduction
The pursuit of sustainable energy has become a global priority as concerns over climate change and depletion of non-renewable energy sources continue to grow. Achieving a sustainable energy future requires a comprehensive understanding of the Earth’s subsurface, where vast reserves of renewable energy resources are located. This is where geophysics, a scientific discipline that investigates the Earth’s physical properties and processes, plays a crucial role. In this article, we will discuss the sustainability of energy and delve into the significant role that geophysics plays in this endeavor.
