Controlled fusion reaction holds the key to solve energy crisis for a long time. It is a source of limitless source of clean energy as byproducts of such a reaction are non-radioactive. Prerequisite being to generate in a safe way temperatures of 1, 000,000 degree C i.e., 10-100 times more than Sun's core temperature for fusion of hydrogen nuclei to take place. In a hydrogen bomb such a high temperature is created by trigering a fission based atomic bomb. National Ignition Facility (NIF) at Lawrence Livermore National Laboratory, California aims to create such a high temperature by focussing the intense energy of 192 giant laser beams on a small target filled with hydrogen fuel - fusing the hydrogen atoms nuclei.

it is a good approaach. It may give some alternate for energy problem. But fission is there again. So I do not think it will solve propose of green energy...
