Did you know that we will run out of fossil fuel deposits in the next several decades? This means that even if climate change was not a concern, we need to make the switch to alternative energy sources at some point in the near future.
But where does the energy stored in fossil fuels come from? What about the energy stored in wind, hydro, biofuel, or other renewable energies? It turns out most of energy sources on Earth all start with the sun. The energy Earth receives from the sun is infinitely more than we, humans, will ever need, but we are not currently taking advantage of all the sun has to offer. In this video, I cover how Earth obtains energy, stores energy, and converts energy, how we can harness these various energy sources and stores, the pros and cons of renewable energies like hydro, wind, solar, and biofuel, the difference between biofuel and fossil fuels and why biofuels are more renewable than fossil fuels, how we can exploit chemical energy like hydrogen.
