  2. Entropy and life - Wikipedia

    en.wikipedia.org/wiki/Entropy_and_life

    Like the Earth as a whole, living things use this energy, converting the energy to other forms (the first law), while producing entropy (the second law), and thereby degrading the exergy or quality of the energy. Sustaining life, or the growth of a seed, for example, requires continual arranging of atoms and molecules into elaborate assemblies ...

    en.wikipedia.org/wiki/Carbon-based_life

    The carbon cycle is a biogeochemical cycle that is important in maintaining life on Earth over a long time span. The cycle includes carbon sequestration and carbon sinks. [4] [5] Plate tectonics are needed for life over a long time span, and carbon-based life is important in the plate tectonics process. [6]

    en.wikipedia.org/wiki/Planetary_habitability

    In its astrobiology roadmap, NASA has defined the principal habitability criteria as "extended regions of liquid water, [1] conditions favorable for the assembly of complex organic molecules, and energy sources to sustain metabolism". [5] In August 2018, researchers reported that water worlds could support life. [6] [7]

  5. Sustainable energy - Wikipedia

    en.wikipedia.org/wiki/Sustainable_energy

    For a given unit of energy produced, the life-cycle greenhouse-gas emissions of natural gas are around 40 times the emissions of wind or nuclear energy but are much less than coal. Burning natural gas produces around half the emissions of coal when used to generate electricity and around two-thirds the emissions of coal when used to produce ...

  8. Energy - Wikipedia

    en.wikipedia.org/wiki/Energy

    Energy transfer can be considered for the special case of systems which are closed to transfers of matter. The portion of the energy which is transferred by conservative forces over a distance is measured as the work the source system does on the receiving system. The portion of the energy which does not do work during the transfer is called heat.

  9. Sustainable living - Wikipedia

    en.wikipedia.org/wiki/Sustainable_living

    Sustainable living describes a lifestyle that attempts to reduce the use of Earth's natural resources by an individual or society. Its practitioners often attempt to reduce their ecological footprint (including their carbon footprint) by altering their home designs and methods of transportation, energy consumption and diet.
