At first, such a star will convert hydrogen-1 into helium-4; later, it will convert helium-4 into heavier atoms, up to about iron.
It will convert hydrogen to helium during much if its life and then convert helium to elements with higher mass such as carbon.
Hydrogen and Helium
Hydrogen.
Many people think nuclear is a suitable alternative. Nuclear energy is clean, with no carbon dioxide pollution, so it does not add to global warming the way that burning fossil fuels (coal, oil and natural gas) does. However, nuclear power has its dangers too. Accidents at power plants can be deadly, and there is no easy way yet to dispose of nuclear waste.
There are many factors that have caused nuclear energy not to be used widely. It can be dangerous, and there have been several disasters or close calls involving nuclear power. It is also not as profitable as fossil fuels, so businesses are less likely to engage.
Three possibilities: Petroleum (23%) + Natural Gas (30%) = 53% or Natural Gas (30%) + Uranium (nuclear energy) (33%) = 63% or Petroleum (23%) + Uranium (33%) = 56% A forth is possible if you consider: Uranium (33%) + Renewable energy (8%) = 41%
All fuels (with the exception of nuclear fuels) were originally dependant on sunshine for their creation. Coal, gasoline, wood, peat, diesel. Nuclear fuels depend on the emission of neutrons from a radioactive substance, and the radioactive materials used all have primal (original) energy available in them. The temperature of the inner core of the Earth is about 5700oC, about the same as the surface of the Sun. This eventually gives us geothermal heat and geothermal energy. The inner core of the Earth is heated by radioactive decay of the heavy elements.
The main problem with fossil fuels is that there is a limited amount of them. At some point we are going to run out. Now this isn't going to happen anytime soon but at some point we will run out of fossil fuels. The other problem of course is that burning fossil fuels releases carbon dioxide which is building up in the atmosphere causing global warming and climate change.
Fossil fuels
Nuclear fissions in nuclear fuels generate heat and electricity.
Nuclear fuels are extremely dangerous and the station could explode.
Nuclear energy does not come from fossil fuels
For example, nuclear fuels.
Fusion is the type of nuclear reaction that fuels your solar system.
fossil fuel is made by the nature and nuclear fuel is not made by the nature
extracting energy from nuclear fuels is more expensive than extracting energy from fossil fuels
Plutonium obtained in nuclear reactors with uranium fuels after recycling of the burned fuels can be used also as a nuclear fuel.
Nuclear fission
Fossil fuels are not used in nuclear power stations. Nuclear fuel is used (uranium)
Because plutonium is needed for nuclear weapons and nuclear fuels.
