[quote=Anonymous][quote=Anonymous]Lawrence Livermore National Lab publishes a sankey chart that shows the US economy-wide energy use and efficiency. It can be found here: [url]https://flowcharts.llnl.gov/commodities/energy[/url] The largest energy consumers and least energy efficient sectors of our economy are the electricity generation sector (35% efficient) and the transportation sector (21% efficient). The buildings sector (both residential and commercial) are the most efficient sectors of our economy at the moment. As an individual, the biggest contributions that you can make to GHG reductions are to minimize your transportation footprint (both via personal transportation and the the transportation footprint of the goods you buy). [/quote] Thx for this information. Can you explain the term "efficiency" in this context? If a sector is 35% efficient, does that mean that 65% of the energy is wasted or lost?[/quote]
