===Second Film===
The second film begins with Bill Nye back in the jungle. While he is looking for Ellen, she swings behind him on a vine and begins to protest the whole adventure. Bill informs her that they are at the dawn of humanity, and a very important discovery is about to take place. Guests then see a caveman discovering fire. Following this discovery a montage of man's progress using various forms of energy (including wind, steam, and gasoline) is shown. The montage ends with Bill and Ellen flying in a helicopter, with Ellen asserting that she is ready for Jeopardy!. Bill tells her that she is not quite ready, and he begins to explain potential future energy sources including solar, wind, and hydroelectric energy- which all have their own problems. Bill also explains fossil fuels such as coal, natural gas, and oil, saying that although these sources of energy will eventually run out, things like off shore drilling and satellites can help us find new sources. Bill and Ellen also discuss how nuclear and fusion energy could also be solutions to our energy problems. The two celebrities end up concluding that as long as we keep working on it, there should be lots of energy options in the future.
