The majority do, but there is one genus of plants that does not rely on photosynthesis for energy. That plant is dodder, a plant parasite that attaches itself to other plants. Dodder contains such tiny amounts of chlorophyll (needed for photosynthesis) that it cannot produce its energy by photosynthesis. Its leaves have shrunk down to tiny scales, as it no longer needs to collect sunlight. It must attach to a host, which becomes its energy source. Basically the chlorophyll in dodder is a left-over from its photosynthesizing ancestors. It isn't how dodder survives.
Other plants all photosynthesize for energy. Venus flytraps and similar get nutrients from animals, but they still generate their energy by photosynthesis and sunlight. Other parasitic plants, like mistletoe, still photosynthesize alongside being parasites. Plants that are not green (such as those with red leaves) still contain chlorophyll and photosynthesize. It is just that they have other pigments in the leaves too.
(Fungi are not plants, as suggested in previous answers. Fungi are their own Kingdom, on the same level as animals and plants)
Wikipedia has a nice article on dodder:

RE:
Do ALL plants use photosynthesis to obtain energy?

Can be true and can be false. True because through photosynthesis they store energy which is released during respiration. False as usually we do not consider photosynthesis as process through wich plants obtain energy.

No! Aren't mushrooms plants and they grow in the dark. There are plants living deep in the oceans of the planet which don't receive enough sunlight for photosynthesis to be possible and subsist on chemical energy sources instead. There must be other examples as well. And yes there ARE plants that aren't green. We're just not used to seeing them.

There are carnivorous plants also which eat insects etc.Example -Pitcher plant.But mostly plants photosinthesise to get energy.

Only the green plants make use of photosynthesis.

Yes that is a requirement of a plant.

Venus fly trap uses that along with energy obtained by it's prey.

Hmm - can you think of a plant that isn't green? If so it couldn't photosynthesise because it needs chlorophyll.
