Wow, pretty impressive growth rate for a electrical source often overlooked or forgotten. Like all technologies, this one continue to improve as well, and production levels versus investments are increasing.
Canada produces megawatts of geothermal energy. They do it very well, and export excess into Eastern US. We need diversity in power. We need duplicity. We need as much as possible generated locally. Seeing geothermal has a bright future helps with these goals.
Note this is an international technology that will see rapid expansion across the world.
