What are the 3 ways to get geothermal energy?

Hot water can be released through geysers, hot springs, steam vents, underwater hydrothermal vents, and mud pots. These are all sources of geothermal energy. Their heat can be captured and used directly for heat, or their steam can be used to generate electricity.

How much does geothermal energy cost per month?

The homeowner said he was paying $150/month for propane, and if we deduce the average geothermal kWh use it would be around $138/month, a savings of $12/month. In today’s dollars, the price of geo is 1/3 the cost of propane, so he would save $3,000 per year.
