Hydrothermal Energy Resources (Illustrated GIF)
Conventional hydrothermal resources occur below the ground where three ingredients combine: heat, water and permeable rock. When heated water or steam is trapped in a porous rock below a layer of less permeable rock, a hydrothermal reservoir is formed.

Enhanced Geothermal Systems (Illustrated GIF)
Enhanced Geothermal Systems are an emerging resource that the USGS studies. To generate electricity from these systems, fractures are engineered into deep, low-porosity hot rocks to allow water to circulate. Then, the heated water is pumped back to the surface, where the thermal energy is used to move a turbine and generate electricity.

Measuring natural methane emissions from bogs using drones in Alaska B-Roll
Measuring natural methane emissions from bogs using drones in Alaska B-RollPermafrost is ground that has been frozen for at least two years. With the warming climate, permafrost across Alaska is thawing and greenhouse gases such as methane are released as a result. Ecologist Kristen Manies of the U.S.
