Right now, we use nuclear fission to produce heat within our nuclear reactors. But for the last few decades, scientists and engineers have been working on reactors that run on nuclear fusion power. Fission is the mechanism that drives atomic bombs (the splitting or decaying atom's nuclei releasing energy), and fusion is what (the combining of high energy atoms into a new element) drives that cores of stars including our own sun. Fusion is sustainable (source: our sun is 4.6+ billion years old), and releases a constant flow of usable energy, making it more efficient than fission.

Fission itself could become more efficient by using heavier elements (yes, even heavier than Uranium), but with such high levels of energy comes even greater dangers and risk. It's debatable whether we could even construct such a resilient an stable reactor with our modern technology.

What action does not make a home more energy efficient?

Leaving lights on when not in use does not make a home more energy efficient as it unnecessarily consumes electricity.


Is solar energy more efficient than nuclear energy?

Solar energy and nuclear energy are both efficient in their own ways. Solar energy is renewable and non-polluting, but it is dependent on weather conditions and location. Nuclear energy is a reliable source of power, but it produces radioactive waste and has associated safety concerns. The efficiency of each depends on factors such as cost, environmental impact, and energy output.


Which action does not make a home more energy efficient?

Leaving lights on when not needed does not make a home more energy efficient. This wasteful practice can increase electricity consumption and utility bills.


Does water have nuclear energy?

Yes, but more specifically, the atoms that make up the water molecule have nuclear energy. Nuclear energy is what hold the atoms together. It holds the nuetrons and protons together within the nucleus of the atom. So anything that has nuetrons and protons has nuclear energy.


What are the key differences between hydrogen and nuclear energy in terms of efficiency, safety, and environmental impact?

Hydrogen energy is less efficient than nuclear energy because it requires more energy to produce hydrogen. However, hydrogen is safer to handle and has lower environmental impact compared to nuclear energy, which produces radioactive waste and poses risks of accidents.

Will putting new windows in my home make my house more energy efficient?

Putting new windows in the home will not make the house more energy efficient. There would have to be a specific type of glass in the window.


Which yields more energy - one kilogram or uranium or one kilogram of coal?

One kilogram of uranium yields significantly more energy than one kilogram of coal. Uranium's energy density is much higher due to nuclear fission reactions, making it a more efficient energy source compared to coal, which relies on combustion for energy production.


What is a nuclearfusion?

Nuclear Fusion, not to be mistaken with Nuclear Fission, is a process in which energy is created due to the merging or "fusion" of subatomic particles. The process is much more energy efficient, and produces larger quantities of energy than in a fission based process.


What are some jobs for Nuclear Engineering?

Nuclear engineering is a job, but I suppose you mean their duties and responsibilities. Nuclear engineers perform a wide range of activities in their field. They dispose of nuclear waste created by nuclear energy, create machines like x-rays and MRI's that can help diseases, stimulate a nuclear accident so that it won't happen in real life, and also work on ways to make energy more efficient.


Is a coal oil burning station more efficient than a nuclear generating station?

Nuclear generating stations are generally more efficient than coal/oil burning stations in terms of energy production per unit of fuel consumed. This is because nuclear reactions are much more energy-dense and produce more power with less fuel. Additionally, nuclear plants have lower operating costs and emit less greenhouse gases compared to coal/oil plants.
