Hydroelectric power is the most widely-used renewable energy source in the world. It creates about one-sixth of the world’s electricity. But how exactly does it work, and how does it fit into our energy future?

Today, we have a thought experiment on our minds. What would happen if we stopped creating greenhouse gas emissions right now? Would climate change be over?

Wind turbines have been popping up across the world as a more sustainable way to create electricity. But these turbines can’t last forever, and not all of their parts can be recycled. In this episode, we look into what happens to wind turbines when they wear out.

Over the last few months, many of us have turned to digital devices to stay connected. We wondered: how much energy are we using with all of this time online?

Today we have a question about paper recycling. What happens after you throw paper into the blue bin? How much of that paper actually gets reused? And is it worth the energy it takes to process it?

Earlier this year, we did an episode comparing emissions for flying versus driving the same distance. But what if you’re driving an RV? Megan runs the number with Stephen after she finishes her own cross-country trip.
