This week we are exploring alternative energy sources. We’ll look at how biomass can be burned as a fuel source, how hydrogen can be used in a fuel cell to generate electrical power, and how nuclear fission provides power to the grid. We’ll also discuss how nuclear fusion might someday do the same without any radioactive waste.

Congrats @England on getting through in the #WorldCup ! So the surge in demand for the #ENG vs #COL⚽️ game was even bigger than we predicted with 1200MGW. That's the same as 400k kettles being turned on. Well done lads – have a cuppa ☕️on us!
