Geothermal Energy Pros/Cons


	Geothermal Energy Pros/Cons
	Advantages Can be very price competitive in the right location and reduces fossil fuel reliance No CO2 emissions Sustainable with water re-injected to extend life of wells and solves problems of disposing of saline groundwater Can work continually (day+night) and not affected by changing weather	Disadvantages Requires suitable geology Danger of volcanic eruptions and earthquakes Can trigger subsidence which triggers earthquakes Only viable for around 20-30 years Water can contain toxic elements. The water is corrosive and salts maybe precipitate out and block pipes
