However, hydrogen is placed in group 1 because it has just one electron in it's outermost shell (which happens to be the only shell it has) just like every other group 1A/group 1 element. While helium is placed in group 8A/group 18 because it has a completely filled outermost shell (which is also the only shell it has) just like every other element in group 8A/group 18.
Non-renewable energy takes a huge amount of time to be naturally created and replenished. Many hundreds of lifetimes, in fact. On the other hand, renewable energy sources are replenished pretty quickly. Biomass is a renewable energy from plants and animals. Biomass is renewable organic material that comes from plants and animals. Biomass was the largest source of total annual U.S. energy consumption until the mid-1800s.
