What are some efficient form of perpetual energy? Why do we insist on using transitory energy?

Answer 1

All energy is transitory. We can never harness 100%, there will always be some escaping in a form that is less or non usable. There is no perpetual energy. This is why we "insist" on using transitory energy. We have no choice.

Answer 2

I think what you mean by transitory energy is whether this is extracted from the ground such as nuclear, oil, coal and gas. Whereas perpetual sources are solar energy, geo-thermal, wind power and waves. Fusion energy can in theory be created from raw materials abundant in the oceans, so this too could be considered perpetual, as could ethanol and biogas from farming.
Now why do we insist on using transitory energy sources, mostly because they are cheap and efficient in terms of weight per unit of energy. Now we see the resources are running low and prices rising, together with the environmental impact of greenhouses gasses we need to invest more in to reseraching these perpetual sources to make them also economically viable.

Answer 3

I'm afraid that this question is ambiguous in the extreme! What is meant by 'perpetual energy'? We insist upon using transitory energy because, in its nature, there is no alternative.

Answer 4

To analyse energy it is necessary to know what it is .
It is not a quantity it is a process.
No matter what system the process is involved in the process always remains the same. This is what Einstein was trying to shown in his search for a Unification theory.
