LINKS TO U.S. GOVERNMENTAL DATA SOURCES MAY BE BROKEN

  Because of the current administration’s redoubled efforts at hiding U.S. climate change and renewable energy information:
         "Archivists Work to Identify and Save the Thousands of Datasets Disappearing from Data.gov" (link / cached copy)
         "Disappearing Data I: Trump Administration Removing Climate Information from Government Websites" (link / cached copy)
         "Disappearing Data II: Distorted Science and Deregulation " (link / cached copy)
 
  And its redirection of the National Renewable Energy Lab (NREL) to no longer conduct or archive such governmental research:
         "Renewable No More: The Trump Administration Renames the National Renewable Energy Laboratory" (link / cached copy)
         "Team Trump Strips Renewable Energy from the Name of an Iconic National Lab" (link / cached copy)

But disappearing information may still be found via my "cached copy" links below
