You can indeed get energy from gravitational contraction. However, theoretical calculations show that this type of energy can in no way power the Sun for 4.6 billions of years - and it is known that Earth, and the Solar System, have approximately that age.
Water itself does not provide energy, but rather is involved in processes that release energy. For example, in hydroelectric power generation, flowing water is used to turn turbines which generate electricity. Additionally, water is essential for various physiological processes in the body that produce energy through cellular respiration.

This is called photo voltaic where electrons move through wires built int the solar panel.
The energy radiated from the Sun is electromagnetic energy.
The nuclear reaction that combines hydrogen to form helium and produces most of the sun's energy is called nuclear fusion. In this reaction, hydrogen nuclei (protons) fuse together to form helium nuclei, releasing a large amount of energy in the form of light and heat.
Chemoautotrophic
Plants use the suns energy to make energy in a process called photosynthesis. The suns energy is used to produce glucose which provides the energy that the plants need to survive through processes such as respiration and expiration.
The sun gravity is stronger
The sun crushes hydrogen into helium with its immense gravity. This makes light and heat. This is a nuclear reaction.
Find a way to defy gravity by creating negative energy, which is currently not possible with today's technology.

keep out Bactria and (I think) it helps it produce vitamin D using the suns energy
The sun itself
The Sun's gravity, at its surface, is about 28 times Earth's surface gravity.
because the sand they grow in doesnt contain energy but the suns light does and from that photosynthesis
no plants don't get diabetes because they produce their own food by the suns energy so they are called autotrophs.
