All stars- including our sun- are an ongoing nuclear fusion reaction- hydrogen is fused into helium. The hydrogen is consumed in that reaction.
Not sure exactly what you mean. However, whether we use solar energy or not, the Sun will continue shining - and using up its fuel. So, in a way, any solar energy we don't use will be wasted.Not sure exactly what you mean. However, whether we use solar energy or not, the Sun will continue shining - and using up its fuel.

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.
Because eventually it will burn out, and use up all its hydrogen fuel. I hear we have about 5 billion years left, so no cause for concern.
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.
we will die
The sun will eventually exhaust its hydrogen fuel and will undergo a transformation into a red giant star. This will happen in about 5 billion years. After that, it will shed its outer layers and become a white dwarf.
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.
Hydrogen is the fuel used by the sun, helium is the waste produced by hydrogen use in the fusion process
Solar cars refuel just by regaining energy from the sun. They use all of that energy to create fuel in order to run. Some solar cars refuel by using wind energy! Solar cars gain energy from the sun or from the wind to store the energy in their fuel tanks and they use up the energy to make fuel that allows them to travel for long distances! Solar cars have no limits on how many times they can regain energy from the sun or from the wind!
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.
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".
The fuel a solar car uses is energy from the sun converted into electricity using solar cells.
