Why Biothermal Energy Matters: Relevance, Practical Applications, and Industry Significance

Biothermal energy, often conflated with geothermal energy, represents a specific subset focusing on the utilization of heat generated from biological processes within the earth's subsurface. Unlike geothermal energy which taps into heat from the Earth's core, biothermal energy harnesses the heat generated by the decomposition of organic matter in landfills, wastewater treatment plants, and other sources of biomass. This organic decomposition generates significant heat, often wasted or even treated as a problem. Biothermal energy offers a solution, converting this waste heat into usable energy for heating, electricity generation, and other applications. Its significance lies in its potential to:

• Reduce reliance on fossil fuels: By providing a sustainable alternative, biothermal energy contributes to reducing greenhouse gas emissions and mitigating climate change.
