They use less electricity and produce fewer emissions than conventional systems, reduce air and water pollution, and provide a comfortable indoor environment for building occupants.
Nearly 500,000 geothermal heat pumps are being used today for heating and cooling throughout the United States in residential, commercial, and government buildings.
Geothermal heat pumps (GHPs) represent a major clean energy technology.
As a commercially viable technology now, GHPs are well positioned to help our nation achieve the increasingly desirable benefits of more efficient, clean energy technologies.
In a landmark technical report (source: "Space Conditioning: The Next Frontier," EPA 430-R-93-004, April 1993), the U.S. Environmental Protection Agency (EPA) found that GHPs are the most energy efficient, environmentally clean, and cost-effective space-conditioning systems available.
NESTheRecord http://www.nextenergysolutions.com/Publicity/NESTheRecord.pdf All of the howling about the Kyoto accord, which will oblige Canada to cut its fossil- fuel emissions, and the furor over rising home heating prices has Dave Hatherton shaking his head.
Why, he asks, would anyone want to burn more fossil fuels and pipe more natural gas and oil across the country when all the clean energy you need to heat and cool your home is in your back yard?
Hatherton is president of NextEnergy Solutions, an Elmira company recently included in Profit magazine's list of Canada's hottest start-ups, as measured by revenue growth over the past two years.
Through a network of 100 dealers across Canada, NextEnergy is in the business of selling geothermal energy equipment that uses the earth itself to heat and cool buildings.
Michaelowa(2001f)2 Many countries with an attractive geothermal potential and geothermal expansion plans have already started to prepare themselves for CDM implementation.
At high CER prices and baselines, geothermal projects can cover a significant share of the investment costs through CER sales.
While forestry projects can help the developers to safeguard water recharge, they do not yield enough CERs to have a real impact on revenues.

Green power is synonymous with "renewable energy": environmentally friendly ways of generating electricity, using resources that are naturally replenished by Mother Nature.
Coal is transported by railroad from mines in the western U.S. and Canada to the power plants.
Switchgrass and other biomass materials provide an alternative crop option; animal waste and crop residues can be sold and reused; and the construction of wind farms or other green power facilities creates jobs and supports local rural economies.
Thousands of homeowners are using solar power to heat their homes and their water, as well as provide natural lighting.

There are two possible sources for it: the radioactive decay of natural radio nuclides which causes the spreading of heat onto the earth surface, and the storage of solar energy in the top earth layers.
This applies, for example, to the town of Erding in Bavaria, which uses water obtained from a depth of 2,000 m both as a heat source and as material.
For this purpose, a district-heating system has been planned for several new neighbourhoods, as well as new thermal baths in the area.
In Erding, an unsuccessful oil exploration well in 1983 produced thermal water of about 65°C at a depth of 2,350 m from the Upper Jurassic karst of the South German molasse basin.

The earth's atmosphere acts as a greenhouse, letting in light and absorbing and reradiating some heat (infrared radiation).
When greenhouse gas levels increase, they trap more heat and the temperature rises.

USGS may authorize either direct procurement of or reimbursement of the expenses incidental to the effective use of the volunteers such as, but not limited to, training, transportation, lodging, subsistence, equipment and supplies. However, the provision for services or expenses must be in accord with volunteer or cooperative agreements made with such individuals, private organizations, educational institutions, or State or local government.

It hopes to link new energy efficient technologies with markets through intelligent policies.
All of the panelists agreed that the key to resolving the energy crisis is to focus on strategies that reduce reliance on fossil fuels, such as restructuring electric utilities, educating and encouraging consumers to use energy-efficient products, offering incentives, and increasing investment in research and development.
There are currently two bills in Congress entitled, "Energy Efficient Building Incentives Act," that provide incentives, available in tax years 2001-2006, for energy efficiency improvements to new and existing buildings.

Geothermal heat pump systems are the most energy efficient, environmentally clean, and cost-effective space conditioning systems available today.
Radiant energy from the sun continuously warms the earth, and the earth absorbs and stores 47 percent of that solar energy.
Geothermal systems are comprised of three main components: a ground loop heat exchanger (durable plastic pipe filled with water, often installed in 250-500 feet deep vertical boreholes), a geothermal heat pump, and an air distribution system.
Irwin, CA -- Alliant Energy Integrated Services completed the design and installation of both geothermal heat pumps and air source heat pumps to provide HVAC for site residences.
