Thethermal energy is the measure of how active thinks( atoms, molecules) are, the faster they move around, vibrate or rotate the higher the energy. If they don't move at all (the absolute zero temperature O K Kelvin the thermal energy is zero.
Therefore its value can not be negative (or thinks move or they don't.
If the question is about possessing electrical energy form the thermal energy sources i e volcanic activities then the is also no negative things. The extraction of heat and converting if for example in to water vapor and using well known steam engine technologies to produce turbine to further produce electricity is straight forward process compering to nuclear fusion or fission.
