How to solve the problem of energy shortage

You don’t produce energy, you use energy, and it is an irreversible process. The second law of thermodynamics decides that.

Energy is intrinsically limited in any local space and time. And energy dissipation is irreversible process according to the second law of thermodynamics. While the endless future generations have no choice but use the limited energy to survive and evolve into future.

There is no unlimited energy and there is no cheap energy, not in money terms but in terms of future generations’ survival time and evolution level.

In the natural process directed manmade social system as it is now, we are all corrupt: the ruling and the ruled, the rich and the poor, the government and the people.

Without change this situation, we all will extinct --- in the future generation, someday.

Asking for cheap, unlimited energy to be used for our “modern” lifestyle, to be up to the living standards of the modern social consensus, is a common people’s corruption. There is no way we can survive this.

All members of the society (and all societies), have to turn to the rational way to survive.

Let us start from ourselves: turn off the air conditions, hot water systems, move out from the areas that not suitable for human dwelling…

Change to rational process runs in rational system so that all these things can be able to realize in non-competitive social conditions.

a.

\(\left(-3,2\right).\dfrac{-15}{64}+\left(0,8-2\dfrac{4}{15}\right):1\dfrac{23}{24}\)

= \(-3,2.\dfrac{-15}{64}+0,8-\dfrac{34}{15}:\dfrac{47}{24}\)

= \(\dfrac{\left(3,2.\dfrac{15}{64}+0,8-\dfrac{34}{15}\right).24}{47}\)

= \(\dfrac{24\left(\dfrac{-34}{15}+0,75+0,8\right)}{47}=\dfrac{24.\left(\dfrac{-34}{15}+1,55\right)}{47}\)

= \(0,51063...\left(\dfrac{-34}{15}+1,55\right)\)= 0,51063... . -0,71666...

= -0,36595...

b.

= \(\dfrac{\dfrac{28}{15}.0,5^2.3+\left(\dfrac{8}{15}-\dfrac{79}{60}\right)}{\dfrac{47}{24}}=\dfrac{0,75.\dfrac{28}{15}+\dfrac{8}{15}-\dfrac{79}{60}}{\dfrac{47}{24}}\)

= \(\dfrac{\left(0,75.\dfrac{28}{15}+\dfrac{8}{15}-\dfrac{79}{60}\right).24}{47}=\dfrac{24.\left(1,4+\dfrac{8}{15}-\dfrac{79}{60}\right)}{47}\)

= \(\dfrac{24.\left(\dfrac{-47}{60}+1,4\right)}{47}=0,51063...\left(\dfrac{-47}{60}+1,4\right)\)

= \(0,51063...\times0,61666...=0,31489...\)
