Aachen University (RWTH Aachen) installs a deep geothermal heat exchanger (GHE) in order to provide geothermal energy for the heating and cooling of its students' service centre SuperC.
During the planning and construction of the GHE special emphasis is put on reduction of costs and emissions (noise, fume) during the drilling operation by technical improvements as well as by the utilization of recyclable construction material.
Also, the project will show that optimised drilling sites and techniques enhance the feasibility of deep GHE in populated areas.

Well-managed solar, wind, geothermal, biomass and hydroelectric power sources produce reliable electricity --causing little to no pollution.
00326885 But when the initial wells were flow-tested, ICE engineers detected the presence of calcite (CaCO3) deposits in the well bores.
Since they lacked instruments to make measurements in the high-temperature environment downhole, they had no way to assess the scope of the problem.
Then, while attending a 1984 Los Alamos workshop for Central Americans on geothermal energy development, ICE engineers learned of the specialized instruments developed by the Laboratory's Earth Science Instrumentation Group to satisfy the diagnostic needs of the Los Alamos hot dry rock geothermal energy program.
These unique logging tools are capable of operating at temperatures up to 300°C and pressures up to 15,000 psi for durations between 8 and 30 hours.

Geothermal heat pumps (GHPs), also known as groundsource heat pumps or "GeoExchange" systems, are among the most efficient and comfortable heating and cooling technologies currently available for homes and other buildings.
GHPs take advantage of the nearly constant temperatures of the earth a few feet below the surface, collecting heat from the earth (or a body of water) during the heating season and transferring heat from the building to the earth (or a body of water) during the cooling season.
· Higher installation cost is paid for in just three to five years of energy savings.
To qualify, the project must be located within the state, the savings must repay the installation costs within 10 years, and it must be the least-cost alternative when considering the installed cost and the projected costs of operation and maintenance over 20 years.

Middle Eastern oil is becoming more and more unreliable, making commerce in America more risky than it should be.
According to the U.S. Department of Commerce, America loses 12,389 jobs for every billion we spend on imports.
The House plan enhances energy conservation, research and development, and provides for security and diversity to the energy supply for the American people.
The renewable fuel standard in the plan will create more than 214,000 new jobs while expanding household income by an additional $51.7 billion over the next decade (Source: Renewable Fuel Association).

Indeed, even if prices eventually recede from their current level of about $40 a barrel to something in the $30 to $35 range, as many expect, analysts predict that most renewable energy projects will not suffer as badly as they once did.
"We're in a very different era from the late 1970's," said Dan Reicher, who served as the top energy official responsible for alternative and renewable energy sources under President Bill Clinton.
Experts debate just how competitive alternative energy sources are versus fossil fuels, though there is no dispute that over all the price gap has narrowed as oil and natural gas prices have soared and new technologies have made alternative sources more efficient.

The production of electricity using geothermal resources is regarded as having low emissions and is eligible for the creation of renewable energy certifi cates under the MRET Scheme1.
Some jurisdictions (such as NSW) treat geothermal resources as a mineral.3 Others (such as South Australia) deal with them as regulated activities under their petroleum legislation.4 Queensland treats geothermal resources as a unique category in its own right.
Regulations may permit extraction only if it is for domestic or associated hot-water usage or for remote power generation of no more than 250kW.

The Bill contemplates a tender process for the granting of exploration permits.

Developing countries need $6 trillion in electricity investment over the next three decades.
China alone will need nearly $2 trillion in electricity investment over the next three decades.
In the developing world, between now and 2030, non-hydro renewable energy is projected to grow at an estimated 5.7 percent per year.

Solarthermal plants can be supplemented with a seasonally operating geothermal deep probe and a heat pump, thus creating an energy supply system in which these devices support each other in an ideal manner.
The system promises high shares of renewable energy and high efficienc y of the solar and the geothermal system at the same time.
While ordinary probes used as temperature reservoirs for heat pumps or storages have a depth of ca. 100 m, the Deep Probe has a depth of ca. 3'000 m, allowing extraction of geothermal heat at ca. 65 C outlet temperature.
Surplus solar energy is used to fasten the regeneration in the lower ground layers around the probe or can be stored in layers closer to the surface.
VortragPS seismicity, plant, power, reservoir, Basel, heat, production, Switzerland, energy, resource, stress field. DEEP HEAT MINING: Development of a cogeneration power plant from an enhanced geothermal system in Basel, Switzerland.
It is intended to drill one injection and two production wells to produce 3 MW electric power and 20 MW thermal power for the local district heating grid from an enhanced reservoir at five kilometres depth.
The plant lies within this seismic active area (Deichmann, 2003).
It is therefore indicated to record and understand the natural seismic activity as accurately as possible, prior to stimulation of a deep reservoir volume, characteristically accompanied with induced seismicity.
The first exploration well, Otterbach 2 drilled in 2001 into granitic basement at 2650 metres to a total depth of 2755 metres.

Trustees recommend implementing what is called a "Percent of Market Value" formula that changes the mechanism by which Permanent Fund earnings that go to pay dividends are calculated.
Assistant Secretary for Energy Efficiency and Renewable Energy, David Garman, and his program manager for geothermal technologies, Dr. Roy Mink, visited Alaska last week to look at a number of geothermal sites around the State and evaluate their viability for energy production.
