An extensive analysis by the Indian Institute of Technology-Hyderabad (IIT-H) and researchers from Monash University, Australia has suggested geothermal energy – the use of the earth’s heat to generate power – is better than photovoltaic energy in terms of carbon dioxide emissions. The researchers also suggest that a combination of renewable energy technology must be adopted in this era of dwindling fossil fuel reserves and increasing greenhouse gas emissions.
This analysis was undertaken by Prof D Chandrasekharam, Department of Civil Engineering, IIT-H, and Prof G Ranjith Pathegama, Department of Civil Engineering, Monash University, Melbourne, Australia. Their Research paper was published recently in the reputed peer-reviewed journal Geomechanics and Geophysics for Geo-Energy and Geo-Resources.
