Best way to get energy?

[jimbo8]

Hello, this is jimbo8. Well, i've built a quarry yesterday(or me and 3 friends built 3 quarries, 2 of them are using one together and i and another one made his own). We got like no more energy! We are using MFE, Glass Fibre Cable, Geo. Generator and energy condenser to make lava cells. What is the best way to get more energy except of nuclear reactor and dangerous stuff?

Greetings, jimbo8.

[EDIT]Sorry for the names, i always write my name first and last. Will not do it next time
