    The Energy Hierarchy is a classification of energy options, prioritised to assist progress towards a more sustainable energy system. It is a similar approach to the waste hierarchy for minimising resource depletion , and adopts a parallel sequence.

  3. Ecological pyramid - Wikipedia

    en.wikipedia.org/wiki/Ecological_pyramid

    When energy is transferred to higher trophic levels, on average only about 10% is used at each level to build biomass, becoming stored energy. The rest goes to metabolic processes such as growth, respiration, and reproduction. [2] Advantages of the pyramid of energy as a representation: It takes account of the rate of production over a period ...

    en.wikipedia.org/wiki/Outline_(list)

    Outlines can be presented as a work's table of contents, but they can also be used as the body of a work. The Outline of Knowledge from the 15th edition of the Encyclopedia Britannica is an example of this. Wikipedia includes outlines that summarize subjects (for example, see Outline of chess, Outline of Mars, and Outline of knowledge).

  5. Energy quality - Wikipedia

    en.wikipedia.org/wiki/Energy_quality

    Energy quality is a measure of the ease with which a form of energy can be converted to useful work or to another form of energy: i.e. its content of thermodynamic free energy. A high quality form of energy has a high content of thermodynamic free energy, and therefore a high proportion of it can be converted to work; whereas with low quality ...

  8. List of books about renewable energy - Wikipedia

    en.wikipedia.org/wiki/List_of_books_about...

    Renewable energy is energy which comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). About 16% of global final energy consumption comes from renewables, with 10% coming from traditional biomass , which is mainly used for heating , and 3.4% from hydroelectricity .

  9. Energy flow (ecology) - Wikipedia

    en.wikipedia.org/wiki/Energy_flow_(ecology)

    While a portion of the energy is used for respiration, another portion of the energy goes towards biomass in the consumer. [16] There are two major food chains: The primary food chain is the energy coming from autotrophs and passed on to the consumers; and the second major food chain is when carnivores eat the herbivores or decomposers that ...
