A Brief History of Geothermal Energy
Use




Used by most if not all early civilizations for
cooking, bathing, and heating.
First used for electric power in Lardello, Italy
in 1913
Did not spread to the rest of the world until
1932
All pumps before 1960 were of the basic dry
steam design
Global Climate Change: Why We Should
Fear It



Rising CO2 levels contribute to a change in global climates
Non-renewable energy sources such as fossil fuels and coal
result in a large amount of CO2 waste products
Global Climate Change has been predicted to result in a
number of issues such as flooding of costal areas, higher
allergen production, a grater risk of food poisoning, a grater risk
of water-borne infection (particularly Cholera in costal/estuarine
areas), grater risk of vector borne infection, reduction in crop
yields, decline in local fisheries, population displacement and
salinisation of freshwater and/or costal soil
Geothermal Energy: An Overview




Energy results from the heat deep benith the
Earth’s surface
Higher temperature areas can be used to
generate energy
Lower temperature areas can be put to
“direct use”
Geothermal Energy can be harnessed almost
anywhere in the world through the use of
geothermal heat pumps




Initially all plants were dry steam plants
In 1960, a flash steam plant was constructed
in New Zealand
Currently, the most effective model is the
binary method

Other innovations in Geothermal
Technology


Can substitute normal water in plant with
recycled wastewater
First attempted at a geothermal energy plant
in California known as “The Geysers”
