The biggest faux-pas in data visualization, so let&amp;#x27;s fix it:&lt;p&gt;X: Days between October 1951 to April 1954.&lt;p&gt;Y: City-wide electricity consumption (Megawatt-hours (?)) in increments of 5MWh.&lt;p&gt;Z: Half-hours in day.&lt;p&gt;Additional info on daily card:&lt;p&gt;- sunrise-sunset time.&lt;p&gt;- several fields for weather information.&lt;p&gt;- illumination.&lt;p&gt;- free form &amp;quot;notable events&amp;quot; annotated on card.&lt;p&gt;Unbelievable someone cut these cards by hand in half-hour, 5MWh increments. Together with keeping track of notable events related to electricity consumption, some administrator filled a full-time job generating this data.</text><parent_chain></parent_chain></comment><story><title>Three-dimensional model of electricity consumption in Manchester (1954)</title><url>https://collection.sciencemuseumgroup.org.uk/objects/co8418916/three-dimensional-model-of-electricity-consumption-in-manchester-chart-graphic-document</url></story>

UK demand curves today don&amp;#x27;t show this much - presumably because people still leave their office computers, servers, etc. on over lunch and overnight.&lt;p&gt;There&amp;#x27;s also a smaller bump at 22h in the 1954 data and it&amp;#x27;s still somewhat present today in the summer data. I can&amp;#x27;t think of a good explanation for it. Perhaps street lighting, only visible as a second bump when they turn on only much later (summer) than the tapering off industrial demand? (An example of different demand types: those following fixed working hours and those following varying day&amp;#x2F;night light hours).</text><parent_chain></parent_chain></comment><story><title>Three-dimensional model of electricity consumption in Manchester (1954)</title><url>https://collection.sciencemuseumgroup.org.uk/objects/co8418916/three-dimensional-model-of-electricity-consumption-in-manchester-chart-graphic-document</url></story>
