The problem is that, although there are a range of different techniques for fusion, most of them produce less energy than is required to sustain the reaction. The most promising systems are "hot" reactors. The reaction takes place under conditions of very high temperature and pressure and it is difficult to safely contain such reactions. There are plans to build a prototype reactor that will produce a net energy output for "many minutes" but, alas, we are several years (possibly many years) from commercial fusion power stations.

When a fusion reactor for safely generating energy is developed the element that could meet Earths energy demands for millions of years is?
The most likely fusion reaction to be exploited for power production is between deuterium and tritium, both isotopes of hydrogen. Deuterium oxide is heavy water and can …be produced from any source of natural water, the technology for this is well known, and obviously there are countless tons of it in the earth's water. Tritium does not occur in nature because it has a short half life, the best way to produce it is to irradiate lithium in a nuclear reactor, so to get tritium you need a supply of lithium, but there is enough known to be sure of many years supply, if not millions of years. A reaction entirely between deuterium atoms is also possible but theoretically it is much less attractive, requiring more energy to start it and producing less energy output than the D-T one.
Because it is a fission process, not fusion
We have currently only put nuclear fusion into two rather destructive purposes. The first of course being Atomic Nuclear weapons, which utilize unbalanced atoms to force mass…ive energy displacements causing heat and a very large explosion. The second slightly better but still bad for everything around it. Nuclear Power Plants use the same force as Atomic Nuclear Weapons in small quantities to create electricity.
As far as I know the sun provides ALL of the energy used by life on earth. Except maybe nuclear by humans, but photosynthesis in plants and that is the same energy stored in s…ugars and then used by metabolism from eating the sugars, oil is the same energy stored millions of years ago and being used now, same with coal, and solar obviously and without the sun there would be no wind so wind power too. And OTHER stars created the heavy elements used for nuclear power by the process of fission(In Theory).
One good reason-it has not been made to work yet! We do of course use solar energy which is produced by nuclear fusion
So far only in bombs.
They do, but if you are asking why it is not done on a larger scale, it has to do with money. For the current energy companies to switch over to a new technology cost money up…front. This will cut into the business's short term profits, and in big business (which is who owns the energy sectors) the short term profits are valued higher than long term.

At this time nuclear fusion is only practical in bombs and stars. Since the early 1950s various experimental apparatus have been tried to determine how to build a fusion react…or. None of these has yet reached breakeven (the point where the same amount of energy is released as needed to be applied to initiate fusion) and one needs to go far beyond breakeven to make a reactor to generate usable power. Every 10 years or so some fusion researchers will claim usable reactors are only another 10 years away... but we are still waiting.

We could use Electricity
We do not currently have the technical knowledge to produce controlled fusion reactors on a scale large enough to produce power. Right now, the only two viable uses of fusion …are in the Sun, and in hydrogen bombs, but the latter is an uncontrolled reaction, not suited for use in a power plant. The problem is that, in order to produce a fusion reaction, you need extremely high temperatures and pressures. That's easy for the Sun to do, because of its enormous mass and gravity, but on Earth it is a problem. Once you have that fusion reaction going, then you need a way to contain it. Unfortunately, there is nothing that can hold the plasma needed for the fusion reaction, because it will burn through anything. Since plasma is a charged stream, we can use magnetic fields to bottle it, so to speak, but in order to produce a strong enough magnetic field, we often need to use super-conducting magnets, which means very, very cold temperatures. The conflict is that we need to maintain pressure and ultra high temperature in close proximity to super-cold temperatures. We just have not been able to accomplish that other than in very, very tiny experiments, with monstrously large machines. Work is ongoing in various labs to attempt this, but I am going to guess that, without the benefit of some stupendous discovery, we are at least 50 or 100 years away from being able to sustain a controlled fusion reaction in a size sufficient to generate commercial power.
Hydrogen. creating helium. For every 1 hydrogen atom fused it creates 4 helium atoms
We could use green energy such as sun and wind. By converting them into electricity, it could provide enough power for the entire house.
that comes from the energy.
None. There is only a transfer of energy. You obtain the energy from a consumed source example: you eat food which causes a transfer of energy but the food does not provide en…ergy.
