That statement is half true. Uranium enrichment is not required to produce electricity in non-nuclear generating plants. However, it is required to produce electricity in a nuclear plant.
"The nuclear fuel used in a nuclear reactor needs to have a higher concentration of the U235 isotope than that which exists in natural uranium ore. U235 when concentrated (or enriched) is fissionable in light-water reactors (the most common reactor design in the USA). During fission, the nucleus of the atom splits apart producing both heat and extra neutrons. Under controlled conditions, these extra neutrons can cause additional, nearby atoms to fission and a nuclear reaction can be sustained. The heat energy released, by the controlled nuclear reaction within the nuclear reactor, can be harnessed to produce electricity. Commercially, the U235 isotope is enriched to 3 to 5% (from the natural state of 0.7%) and is then further processed to create nuclear fuel."

Article IV of the Nuclear Non-Proliferation Treaty, which America signed, specifically grants to all signatories, including Iran, the right to use nuclear energy for peaceful purposes. Since production of nuclear energy by definition involves the use of enriched uranium, we really don't have the right to forbid Iran from producing and using enriched uranium to produce electricity in a nuclear plant. For us to go to war against Iran, to prevent them from using enriched uranium to produce electricity, would be a violation of the treaty which we signed.
Somebody please give us a better reason to go into a stupid forever war in the Middle East. Or else, let's call the whole thing off.
