Anyone know any good power mods?

I know in ATM9 you have powah and mekanism and loads more but I wondered if anyone knows any power mods which produce a good amount of power but don’t require massive reactors or super resources I can’t seem to find… just trying to make it a bit easier I suppose cause I’m still learning the mechanics of the whole pack😁

Update - still mainly using the netherite generators (which I think is from the ATM9 pack) and I’ve started using energy cubes for on the go power or a backup reserve. I’ve started powah tho and am upgrading slowly
