Turning red-hot lava from an active volcano into electricity would be dangerous and unreliable. But many countries, including the U.S., have found ways to tap volcanic heat to make electricity.

Could We Use Volcanoes To Make Electricity?

NASA’s Solar Dynamics Observatory captured this image of a solar flare – as seen in the bright flash on the left – on Dec. 31. 2023. The image shows a blend of 171 and 131 Angstrom extreme ultraviolet light that highlights the extremely hot material in flares and which is colorized in blue and gold. (Credit: NASA/GSFC/SDO)
