Our Energy Sources, Geothermal — The National Academies (2)

Geothermal Energy UsesGeothermal power is a carbon cost-free, renewable, sustainable form of power that supplies a continuous, uninterrupted supply of heat that can be utilized to heat properties and office buildings and to produce electricity.

The EGS notion is to extract heat by creating a subsurface fracture system to which water can be added through injection wells. Making an enhanced, or engineered, geothermal method requires improving the natural permeability of rock. Rocks are permeable due to minute fractures and pore spaces involving mineral grains. Injected water is heated by contact with the rock and returns to the surface by way of production wells, as in naturally occurring hydrothermal systems. EGS are reservoirs created to strengthen the economics of resources with out sufficient water and/or permeability.

SIG began geophysical surveys on 18th August 2014, along the Chancy road amongst Chancy and Bernex. Two techniques are applied depending on the layout of the land: ground-penetrating radar and resistivity. No drilling is carried out in the course of this phase, as only radio waves are used to map beneath the surface. Additional surveys will be carried out across the Geneva canton.

Most volcanic eruptions and earthquakes occur near plate boundaries. Frequent earthquakes produce fractures in bedrock, as a result allowing water to circulate at depth and to transport heat toward the earth’s surface. Regions of stretched and fault-broken rocks (rift valleys) within plates, like these in East Africa and along the Rio Grande River in Colorado and New Mexico, also are favorable target regions for high concentrations of the earth’s heat at somewhat shallow depths.

There will generally be folks hunting to uncover one thing wrong with energy solutions. I seriously doubt a couple of, or even a couple of hundred tidal energy plants will have any impact on Earths rotation. If practically nothing else we could replace old bridges with new ones cotaining this sort of technologies when they will need to be rebuilt, and it would serve its goal as a both bridge and a energy plant, with out causing any additional lag than is already created by the existing a single.
