  2. Geothermal energy - Wikipedia

    en.wikipedia.org/wiki/Geothermal_energy

    Geothermal heating is the use of geothermal energy to heat buildings and water for human use. Humans have done this since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 2004. As of 2007, 28 GW of geothermal heating satisfied 0.07% of global primary energy consumption. [4]

  3. Human thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Human_thermoregulation

    As in other mammals, human thermoregulation is an important aspect of homeostasis. In thermoregulation, body heat is generated mostly in the deep organs, especially the liver, brain, and heart, and in contraction of skeletal muscles. [1] Humans have been able to adapt to a great diversity of climates, including hot humid and hot arid.

  4. Geothermal heating - Wikipedia

    en.wikipedia.org/wiki/Geothermal_heating

    Geothermal heating is the direct use of geothermal energy for some heating applications. Humans have taken advantage of geothermal heat this way since the Paleolithic era. Approximately seventy countries made direct use of a total of 270 PJ of geothermal heating in 20

  5. Geothermal gradient - Wikipedia

    en.wikipedia.org/wiki/Geothermal_gradient

    Heat may be generated by tidal forces on Earth as it rotates (conservation of angular momentum). The resulting earth tides dissipate energy in Earth's interior as heat. The radiogenic heat from the decay of 238 U and 232 Th are now the major contributors to Earth's internal heat budget. In Earth's continental crust, the decay of natural ...

  6. Cold and heat adaptations in humans - Wikipedia

    en.wikipedia.org/wiki/Cold_and_heat_adaptations...

    There are two types of heat the body is adapted to, humid heat and dry heat, but the body adapts to both in similar ways. Humid heat is characterized by warmer temperatures with a high amount of water vapor in the air, while dry heat is characterized by warmer temperatures with little to no vapor, such as desert conditions.

  7. Ocean heat content - Wikipedia

    en.wikipedia.org/wiki/Ocean_heat_content

    The ocean heat content (OHC) has been increasing for decades as the ocean has been absorbing most of the excess heat resulting from greenhouse gas emissions from human activities. [1] The graph shows OHC calculated to a water depth of 700 and to 2000 meters. Ocean heat content (OHC) or ocean heat uptake (OHU) is the energy absorbed and stored ...

  8. Geothermal activity - Wikipedia

    en.wikipedia.org/wiki/Geothermal_activity

    Geothermal energyThermal energy generated and stored in the Earth; Geothermal gradient – Rate of temperature increase with depth in Earth's interior; Geothermal heating – Use of geothermal energy for heating; Geothermal power – Power generated by geothermal energy

  9. Energy development - Wikipedia

    en.wikipedia.org/wiki/Energy_development

    Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is the energy that determines the temperature of matter. The geothermal energy of the Earth's crust originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%). [102]
