And happy "Thank Energy Day" too!
Institute for Energy Research (8/30/19) blog: "Labor Day commemorates productive America. Begun in the late 19th century by the U.S. labor movement, the first Monday in September is celebrated annually as a public holiday. The unofficial end of summer also is a peak travel time. This Labor Day weekend, a record 17.5 million passengers are expected to fly to hundreds of U.S. destinations and around the world, according to the trade group Airlines for America. And that means a high demand for energy, specifically petroleum to fuel the planes. Labor Day could also be called Thank Energy Day. Human productivity is enabled by the appliances and machines that run on mineral (dense) energies, either directly or indirectly via electrical generation."
