Schnitzel study that follows the price comparison of conventionally raised meat vs. organic, free range meat. Links below to the actual study and other reactions.
Super cool video about Kombikraftwerke. Very interesting piece about a power plant combining wind, solar, and biogas. Includes a great animation about what happens when there is extra energy from wind turbines and when there is not enough.
Great video. There are no subtitles, though, so some of it may be difficult for students to understand. Definitely an advanced video in terms of language and, probably, content.
