Note that 68.2% of the energy generated is lost as heat or in transmission. A similar figure (66.4%) applies to [[Energy|electricity]] generation alone, which remains dominated by thermal production (natural gas, coal, and nuclear), in which only around one-third of the energy contained in the source is converted to [[Energy|electrical energy]].

It should be noted that production from intermittent sources, i.e., wind and solar, represents only a fraction of the turbine or panel’s [[capacity]]. A [[wind turbine]], for example, generates electricity at an annual average rate of 25%–35% of its capacity.<ref>https://www.eia.gov/electricity/data/eia923/</ref> And it generates at or above its average rate only 40% of the time.<ref>https://wind-watch.org/pix/displayimage.php?pid=44</ref><ref>https://wind-watch.org/pix/displayimage.php?pid=42</ref>
