How Does this Technology Work?

 

---

Hot rocks underground heat water to produce steam.

We drill holes down to the hot region, steam comes up, is purified and used to drive turbines, which drive electric generators.

There may be natural "groundwater" in the hot rocks anyway, or we may need to drill more holes and pump water down to them

What can this Type of Energy be Used For?

Creates electricity to power houses, using less factories and oil.

What are the Positive Aspects?

1 is Globally Sustainable.

2still safer than fossil fo.

3 a Base-load energy source.

What are the Negative Aspects?

1.Greenhouse gas emissions: Geothermal electric plants emit an average of 122 kg of CO² per megawatt-hour (MW·h) 
       of electricity.

2.Toxic chemical emissions: Hot water from geothermal sources will contain trace amounts of dangerous element    such as mercury, boron, arsenic, antimony, etc.

3.Localized Depletion: The 3 oldest Geothermal sites have been experiencing what is known as "Localized Depletion" of Heat and Water
