The first dry-steam power plant was constructed in Larderello, Italy, in 1911. In order to produce more energy than the pumps consume, electricity generation requires high-temperature geothermal fields and specialized heat cycles. This refrigerant has a much lower boiling point than water, meaning it is converted into gas at low temperatures. The steam and excess warm water produced by the flash-steam process heat icy sidewalks and parking lots in thefrigidArctic winter.The islands of the Philippines also sit over a tectonically active area, the "Ring of Fire" that rims the Pacific Ocean. Electricity generated from geothermal plants is projected to increase from 16billion kWh in 2021to 47.7billion kWh in 2050. However, this process can cause micro-earthquakes. Although most of these are too small to be felt by people or register on a scale of magnitude, sometimes the ground can quake at more threatening levels and cause the geothermal project to shut down, as it did in Basel, Switzerland. Enhanced Geothermal System (EGS) is a technology under development that could expand the use of geothermal resources to new geographic areas. The 'fuel' of geothermal energy, the heat that is emitted from the earth's crust, is free! Geothermal energy is heat that is generated within the Earth. Flash-steam power plants use naturally occurring sources of underground hot water and steam. The Dixie Valley toad was the first new toad to be described in the United States in the past 50 years. Direct-use applications include space and district heating, greenhouses, aquaculture, and commercial and industrial processes.
