  2. Greenhouse gas emissions - Wikipedia

    en.wikipedia.org/wiki/Greenhouse_gas_emissions

    Though total CO 2 emissions (size of pie charts) differ substantially among high-emitting regions, the pattern of higher income classes emitting more than lower income classes is consistent across regions. [199] The world's top 1% of emitters emit over 1000 times more than the bottom 1%. [199]

  3. Climate change mitigation - Wikipedia

    en.wikipedia.org/wiki/Climate_change_mitigation

    This pie chart illustrates both total emissions for each income group, and emissions per person within each income group. For example, the 10% with the highest incomes are responsible for half of carbon emissions, and its members emit an average of more than five times as much per person as members of the lowest half of the income scale.

    This is an accepted version of this page This is the latest accepted revision, reviewed on 24 January 2025. Gas in an atmosphere with certain absorption characteristics This article is about the physical properties of greenhouse gases. For how human activities are adding to greenhouse gases, see Greenhouse gas emissions. Greenhouse gases trap some of the heat that results when sunlight heats ...

    Though total CO 2 emissions (size of pie charts) differ substantially among high-emitting regions, the pattern of higher income classes emitting more than lower income classes is consistent across regions. [11] The world’s top 1% of emitters emit over 1000 times more than the bottom 1%. [11]

  7. Spreadsheet - Wikipedia

    en.wikipedia.org/wiki/Spreadsheet

    Many spreadsheet applications permit charts and graphs (e.g., histograms, pie charts) to be generated from specified groups of cells that are dynamically re-built as cell contents change. The generated graphic component can either be embedded within the current sheet or added as a separate object.

  8. Rule of 72 - Wikipedia

    In wanting to know of any capital, at a given yearly percentage, in how many years it will double adding the interest to the capital, keep as a rule [the number] 72 in mind, which you will always divide by the interest, and what results, in that many years it will be doubled. Example: When the interest is 6 percent per year, I say that one ...

  9. Multi-junction solar cell - Wikipedia

    en.wikipedia.org/wiki/Multi-junction_solar_cell

    The maximum theoretical efficiency is 37, 50, 56, 72% for 1, 2, 3, 36 additional pn junctions, respectively, with the number of junctions increasing exponentially to achieve equal efficiency increments. [24] The exponential relationship implies that as the cell approaches the limit of efficiency, the increase cost and complexity grow rapidly.
