<i>practically free energy</i><p>We&#x27;ve heard that before, as far back as 1954: &quot;too cheap to meter&quot;. The problem is, even if the incremental generation of electricity is practically free, there are still large costs in building the windmills and solar panels. And there are large distribution costs as well.<p>In addition, the more cheap energy there is, the more inefficiently people will use it. Why bother with things like Energy Star and LEED? Just build inefficient power supplies and poorly insulated buildings. After all, it is &quot;practically free&quot; to heat them and cool them.<p>Post scarcity energy is a non-starter. Consumption will always increase as necessary. Here&#x27;s an even more crazy example: just how much bitcoin (or similar) mining would there be if energy were cheap? It&#x27;s already a disgusting misuse of resources, it would be a lot worse!<p>[1] <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Too_cheap_to_meter" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Too_cheap_to_meter</a>
