The Sun primarily converts hydrogen into helium through nuclear fusion, using approximately 600 million metric tons of hydrogen every second. Over its 4.6 billion-year lifespan, it has consumed around 100 times its current mass in hydrogen. However, it still has enough fuel to continue this process for about another 5 billion years before transitioning into its next stages of evolution.
The sun is mostly made up of hydrogen, undergoing nuclear fusion to produce energy. It is estimated that the sun has used about half of its hydrogen fuel in its core, and it has enough fuel left to continue shining for about another 5 billion years.
Massive stars are more likely to use up their nuclear fuel the soonest. They burn fuel at a much faster rate due to their higher temperatures and pressures, resulting in shorter lifespans compared to smaller stars like our Sun.
The Sun has been shining for about 4.6 billion years and is expected to shine for another 5 billion years. It has currently used up around half of its hydrogen fuel in the core, which is what fuels its nuclear reactions.
Hydrogen makes up about 75% of the sun's mass. It is the primary fuel source for the sun's nuclear fusion reactions that produce energy.
The sun burns continuously due to nuclear fusion in its core, where hydrogen atoms fuse to form helium, releasing a huge amount of energy in the process. This process produces the heat and light that we receive from the sun. As long as there is enough hydrogen fuel in the sun's core, it will continue to burn and emit energy.

The fuel gauge is located in cars. It is used to tell how much fuel is left in the tank. When this gets low the tank will need filling up with more fuel.
Solar energy does run out. The Sun is using up its fuel, all the time. At some moment (oh, in the very, very distant future), the Sun will have no more fuel, and it will stop shining. Long before this happens, it will become unstable, and shine much brighter. In other words, it looks as if our descendants will not die from cold, or lack of food (plants need the Sun's energy), but from heat.Solar energy does run out.

Why not? It blows after few millions after. That called the death of a star .when all the fuel the sun contains is used up by it, the balance between its gravity and the outward radiation prressure is disrupted (gravity will win) then the sun collapses 3o become a red giant. Thats how sun blows off.
The sun is burning gasses just like the stars. And just like any star, when the gas runs out, it will stop burning and disappear.
Proxima Centauri is a "red dwarf" star. Its composition is similar to the Sun, but with less mass and it's much smaller than the Sun. It has lower core and surface temperatures. The Sun will eventually start to use helium as well as hydrogen as its fuel It will become a red giant then a white dwarf. Red dwarfs don't have a high enough core temperature to use helium as as "fuel". Proxima Centauri will not become a red giant. It will go straight to the white dwarf stage, once it has used up its hydrogen "fuel".
we will die
Gravity contracts them more, making them hotter. As a result, they burn up their fuel faster.

A blue star has much greater mass and thus the temperatures in the core are much greater. This means it will use up it's supply of hydrogen much faster than our Sun.
