  1. Earth By: Grace Piller

  2. Earth Energy • Hydroelectric Energy • The production of electrical power through the use of the gravitational force of falling or flowing water. • Biomass Energy • Organic materials that can be burned and used as a source of fuel. Wood being the main source of biomass such as saw-dust or any type of waste from wood. • Geothermal Energy • Energy that is derived from the heat in the interior of the earth. • Wind Energy • Is the conversion of wind power into a useful form of energy by using wind turbines of windmills to make electricity. • Solar Energy • Radiant light and heat from the sun to make electricity.

  3. Types of Use • Earth Sheltering • Is an architectural practice of using earth against building walls for external thermal mass, to reduce heat loss, and to easily maintain a steady indoor temperature.

  4. Earth Sheltering • Advantages • Because earth covers part or all of their exterior, earth-sheltered houses require less outside maintenance, such as painting and cleaning gutters. Constructing a house that is dug into the earth or surrounded by earth builds in some natural soundproofing. Plans for most earth-sheltered houses "blend" the building into the landscape more harmoniously than a conventional home. Finally, earth-sheltered houses can cost less to insure because their design offers extra protection against high winds, hailstorms, and natural disasters such as tornados and hurricanes. • Disadvantages • As with any type of unusual construction, there are some disadvantages associated with earth-sheltered housing. Principal downsides are the initial cost of construction, which may be up to 20% higher, and the level of care required to avoid moisture problems, during both the construction and the life of the house. It can take more diligence to resell an earth-sheltered home, and buyers may have a few more hurdles to clear in the mortgage application process.

  5. Types of Use • Geothermal • The heating/cooling systems operate via subsurface conductive heat transfer, using the naturally renewable temperature of the earth’s curst as a heat source in the winter and as a heat sink in the summer.

  6. Advantages • Significant Cost Saving • No Pollution • Direct Use • Job Creation and Economic Benefits • Disadvantages • Not Widespread Source of Energy • High Installation Costs • Can Run Out Of Steam • May Release Harmful Gases • Suited To Particular Region

  7. Various Elements • What you can build out of: • Stone: mountain sides • Dirt: side of a hill • Ice: the Ice Hotel

  8. Noteworthy Residential Precedence • Earth House by: Peter Vetsch • Located in Deitikon, Switzerland • The earth structure houses provide organic forms, they are based on the interpretation of an environmentally conscious, ecological and progressive architecture

  9. The residential settlement consists of nice houses, three 3 bedroom, a 4 bedroom, a 5 bedroom, three 6 bedroom and a 7 bedroom house. The earth-house concept uses the ground as an natural insulating blanket that efficiently protects it from rain, low temperatures and wind.

  10. Climatic Concerns • The climate in your geographical area will determine whether an earth-sheltered house can be a practical housing solution. Studies show that earth-sheltered houses are more cost-effective in climates that have significant temperature extremes and low humidity, such as the Rocky Mountains and northern Great Plains. Earth temperatures vary much less than air temperatures in these areas, which means the earth can absorb extra heat from the house in hot weather or insulate the house to maintain warmth in cold weather.

  11. Costs • Sheltered Homes • Comparing cost factors for building an earth-sheltered house to those for building a conventional house can be like comparing apples and oranges. Costs vary by region, depending on the area's construction activity and cost of materials. Many earth-sheltered houses are built by their owners and are customized in different ways, adding amenities that can dramatically increase final costs.

  12. Costs • Geothermal Energy • While each house is unique, the usual cost of a geothermal well system can range from about $9,000 to $13,000, depending on your home’s requirements. • In a recent customer survey, it was found that homeowners saved 30-50% on their heating and cooling bills after installing geothermal systems. A home's value increases by $10-25 for every $1 reduction in the annual utility bill, according to the National Association of Realtors Appraisal Journal • There are many tax breaks to homeowners that decide to use Geothermal Energy for their homes.
