The second law says that each time energy gets transferred or transformed, some of it, and eventually all of it, gets less useful. That’s the truth. It gets less useful, until finally, it becomes mostly useless (at least as far as its ability to make things happen is concerned).
It seems like the good times will go on forever, so feel free to keep on wasting energy. But entropy is patient, and eventually, it’ll make sure there’s no usable energy left in the Universe. Thanks to the donations of generations of dinosaurs and their plant buddies, we’ve got fossils to burn.
We always lose. The electricity made by our little turbine isn’t enough to keep the system going. It will eventually “wind down” and stop, because all of the energy will eventually become low-grade and useless. The only way to keep it going is to replace the “lost” energy with some concentrated energy from outside the system.
That’s the truth. It gets less useful, until finally, it becomes mostly useless (at least as far as its ability to make things happen is concerned). All of the energy we use ends up, sooner or later, as what we engineers like to call “low-grade” energy.
Can energy become useless?
yes and no. Energy cannot be created or destroyed, but it can change from more-useful forms into less-useful forms. As it turns out, in every real-world energy transfer or transformation, some amount of energy is converted to a form that’s unusable (unavailable to do work).
Will all energy eventually become heat?
All energy ends up as heat energy. So if a lightbulb is on it will get hotter, however the lightbulb eventually cools down, meaning the heat has gone into the air.
What eventually happens to all energy?
The total amount of energy and matter in the Universe remains constant, merely changing from one form to another. The First Law of Thermodynamics (Conservation) states that energy is always conserved, it cannot be created or destroyed.
What happens useless energy?
Energy is converted from usable form into an unusable form. Take that battery. It can act as a source of energy, powering a light or a motor, for instance. In the process, the chemical potential energy stored in the battery is first converted into electrical energy, and then into light, heat, or motion.
What type of energy can be transformed into another type of energy?
Electric generator (Kinetic energy or Mechanical work u2192 Electrical energy) Fuel cells (Chemical energy u2192 Electrical energy) Battery (electricity) (Chemical energy u2192 Electrical energy) Fire (Chemical energy u2192 Heat and Light)
What is an example of one type of energy being converted into another type?
Kinetic energy and electricity are the most useful forms. These are “high-quality” because they can be transformed almost completely into any other type of energy.
What are three examples of energy being changed from one form to another form?
Battery (electricity) (Chemical energy u2192 Electrical energy) Fire (Chemical energy u2192 Heat and Light) Electric lamp (Electrical energy u2192 Heat and Light) Microphone (Sound u2192 Electrical energy)
What are 5 examples of energy transfer?
An energy transformation is the change of energy from one form to another. material that does not conduct heat, electricity, light, or sound. power or force an object has because of its motion. Light energy is a form of electromagnetic radiation.
What is energy being changed from one form to another?
For example: Plants capture light energy from the sun and convert it into chemical energy during the process of photosynthesis. Wind turns a wind turbine to produce mechanical energy, which activates an electrical generator to produce electricity for a radio.
What is to change from one form to another?
Energy can change from one form to another. For example, when you switch on a lightbulb, electrical energy changes to thermal energy and light energy. A car changes energy stored in the chemical bonds of gasoline to several different forms.
What is the change from one form of energy to another called?
Energy conversion, also termed as energy transformation, is the process of changing one form of energy into another.
What is always produced during energy transformations?
Thermal energy is almost always produced by an energy transformation.
More Answers On Will All Energy Eventually Become Useless
Will all energy eventually become useless? – Quora
Answer (1 of 3): Yes, absolutely. This is called maximum entropy. The energy in the known universe is always the same. We can only “use” energy gradients, where it is concentrated in areas and wants to flow to lower energy levels. Once all energy reaches equilibrium we can no longer use it to do …
If Energy cannot be created, and the Universe IS expanding, will the …
Probably. In an infinitely expanding universe (which we think we have), you will eventually reach a point of maximum entropy where the energy is evenly distributed, and essentially nothing happens.
Will gas become obsolete? | Debate.org
Gasoline and other petroleum based fuels are a finite resource and will therefore, eventually, most likely become obsolete. This could come about in a variety of ways, from unlikely but not uncool apocalyptic oil wars, to more likely scenarios of the price crude oil becoming too high to justify using it as a fuel source.

how energy flows from useful to useless. – FT Exploring
That’s the truth. It gets less useful, until finally, it becomes mostly useless (at least as far as its ability to make things happen is concerned). All of the energy we use ends up, sooner or later, as what we engineers like to call “low-grade” energy. This low-grade energy is only good for warming the air around us a little bit.
Why Renewable Energy Will Replace Fossil Fuels
But partisanship was only one part of the story: Pew’s most significant finding was that age is a significant factor in attitudes toward renewable energy. The strongest support for renewable energy was from those aged 18-29. Among young people, 75% favored alternative energy compared to 19% interested in developing new sources of fossil fuels.
Renewables are useless: The Evidence is Overwhelming
If your statement made sense, than all electric energy producing plants would be broke or at least useless, as they convert potential energy to less electromagnetic energy (warming the atmosphere or river or sea in the process). Even a child could see that.
Life After Energy: What if fossil fuels disappeared tomorrow?
Related to the first point, toilets would be useless without water to flush them. Fecal matter disposal becomes an issue as gravity fed sewage systems eventually clog, and eventually fecal matter will end up in streams and rivers contributing to the spread of diseases much like the Great Stink in old London.
When will we run out of oil, and what happens then?
Basically, the impact of oil shortages can be lessened by decreasing our reliance on fossil fuels. Alternative energy sources and renewable biofuels play a crucial role in these outlooks. Some commentators even go so far as to see eventual oil shortfalls as a stabilizing factor in world politics [source: Drezner]. The writing is on the wall.
Why Natural Gas isn’t Likely to be the World’s Energy Savior
In order for natural gas to be an energy savior for the world, natural gas consumption would need to increase far more than 2.7% per year, and outdistance the increase in coal consumption each year. While a modest increase from past patterns is quite possible, I don’t expect a miracle from natural gas.
Good News! Eventually The Universe Will Become Too Cold And Everything …
So all those processes that use energy and heat – mechanical, chemical, electric, nuclear, and yes, even life – won’t have the stuff that makes things do things. The universe will slowly freeze, and everything in it – everything that has been and will be – will die. It’s totally unavoidable and inevitable.
Will humans be useless after robots take over future jobs
If the corporations have effective control over the government, if the government thinks and acts like a business, then people will have no jobs, no resources, no power. They will become a useless, resource consuming burden. The hungry disenchanted masses will riot in the streets, having no other purpose in life.

Answer (1 of 15): Most of the mass energy (mass of protons, neutrons, and electrons) will remain as mass energy, unless it turns out that the protons do decay, as predicted in some theories. The heat energy will eventually drop to zero, since the expansion will tend to cool regions of space. So…
