Part 6/8:
The potential for geothermal energy is staggering. Some estimates speculate that it could satisfy up to 20% of global electricity demand, standing alongside other renewables to provide consistent, reliable power. This energy source could effectively replace a significant portion of fossil fuels, which currently dominate the energy landscape.
However, this transition will not happen overnight; while geothermal energy offers safety and minimal waste compared to nuclear energy, scalability remains a pressing issue. The high initial investments in technology and infrastructure, along with geographic limitations on the availability of accessible hot rocks, pose considerable barriers that need to be addressed.
