The Future of Clean Energy: Crash Course Engineering #31

The video discusses the urgent need to transition to cleaner energy sources due to climate change and the eventual depletion of fossil fuels. It explores various alternative energy sources, including biomass, hydrogen fuel cells, nuclear fission, and nuclear fusion. Biomass energy is derived from burning biological matter, while hydrogen fuel cells use a chemical reaction to generate power. Nuclear fission is a non-renewable source with challenges like nuclear waste, whereas nuclear fusion holds promise for a sustainable future. Engineers play a crucial role in developing these technologies.

How does the use of biofuels impact carbon dioxide emissions compared to fossil fuels?

What are the challenges associated with nuclear fusion as a power source?
