We use the sun's energy for solar power, photosynthesis, and even in the fossil fuels we burn.Because many things were once living organisms or were once made from living organisms, measuring the percentage of carbon-14 in an artifact is a very reliable way of being able to tell how old the artifact is.Our next application of nuclear chemistry is in medicine.Fossil fuels are really just dead organisms that once used the sun for energy and that have been under a great deal of pressure by being buried under rocks.So, right now on Earth, we can't run our own nuclear fusion reactors, but we still rely heavily on the fusion reactions that take place on the sun.
