Biome Reactors adds a sole block: The Biome Reactor. This block allows the exchange of Redstone Flux(commonly referred to as RF) in order to change the biome in a 7 block radius. Different blocks have to be put inside the reactor for each different biome. It usually uses around 400,000 RF to change the biome.
