Uranium can be "recharged" from isotope 238 to isotope 235 but it is an expensive process and it is more economical to mine more since Uranium is about as common as Tin in the earth's crust. Depleted Uranium (238) is an extremely dense metal and has found its way into a few (mostly military) applications such as certain modern tank armor and special armor piercing bullets. This is the only practical way of "reusing" Uranium.
Geothermal energy is a renewable energy source because the heat is continuously produced inside the Earth.
Ofcourse it is you can go screw yourself now :)
reusable
If it is stored in the nucleus, it must be nuclear energy.
Yes, nuclear energy is energy.
Nuclear energy and renewable energy are not related. Renewable energy does not use nuclear energy.
What is the question
Because wind energy is reusable and never runs out and does not harm the planet.
reusable
No, reusable is not the same as renewable. When a wind passes through a wind turbine it loses energy, so that mass of air has to regain energy before it can be used again.
If it is stored in the nucleus, it must be nuclear energy.
All power (or equivalently energy) is reusable. The problem is keeping it in a form that can be easily reused.
Yes, nuclear energy is energy.
Nuclear energy
Nuclear fusion produces nuclear energy
The energy released is nuclear energy.
Uranium is used as nuclear fuel in nuclear reactors.
Nuclear energy and renewable energy are not related. Renewable energy does not use nuclear energy.
Nuclear energy is converted to electrical energy in a nuclear power plant.
