The modern use of is little more than pumping electrons to power electrical equipment, in the same basic fashion that running water was used to run . The electron flow, like running water, is not the ultimate source of energy, but is just an energy flow that humans harnessed, although humans the electron flow, unlike the . With electricity, the first major applications had . But coal-fired electric generators quickly became the standard, for the , and coal power today provides . Electrons pumped across copper wires became a major innovation that led to modern homes and cities. Before electricity was used to transmit energy, power was only available at the site where usable energy was produced. Watermills, windmills, and heat engines transmitted pre-electrical energy via gears, straps, and pulleys, which were cumbersome and dangerous. With the , factories became far more versatile and humane, and as cities and homes were electrified, they were radically transformed. The USA led the world in introducing electrical appliances to homes; refrigerators, thermostatically controlled central heating and air conditioning, vacuum cleaners, washing machines, dryers, dish washers, radios, televisions, and computers, to name a few innovations, made the early 21st century’s home virtually unrecognizable to a home-dweller during the USA’s Civil War. Electricity also powers the process used today to , and modern equipment of all kinds would simply be infeasible without electricity.

Then I got an apple and did the same thing with the apple and the other fruits and vegetables.

Above all else, life is an energy acquisition process. All life exploits the potential energy in various atomic and molecular arrangements, or captures energy directly, as in photosynthesis. Early life exploited the . The chemosynthetic ideal is capturing chemicals fresh to new environments that have yet to react with other chemicals. The currently most-accepted hypothesis has life first appearing on Earth about 3.5-3.8 bya, probably in volcanic vents on the ocean floor. The earliest life forms took advantage of fresh chemicals introduced to the oceans. Life had to be opportunistic and quick in order to capture that energy before other molecules did.

Those processes and events can interact with each other, and a few examples can provide an idea of the dynamics’ complexity. What follows are today’s orthodox views, to the best of my knowledge, and they can certainly change in the future, perhaps even radically, just as cosmological and subatomic theories may change radically. It seems to me, however, that geophysical and geochemical processes are understood better and have more robust data than many other areas of science, so geophysics and geochemistry are areas where I expect fewer radical changes than others. Maybe that is because it is neither too big nor too small and closer to our daily reality than distant stars or what is happening inside atoms.

As with other early life processes, the first photosynthetic process was different from today’s, but the important result – capturing sunlight to power biological processes – was the same. The scientific consensus today is that a respiration cycle was modified, and a in a was used for capturing sunlight. Intermediate stages have been hypothesized, including the cytochrome using a pigment to create a shield to absorb ultraviolet light, or that the pigment was part of an infrared sensor (for locating volcanic vents). But whatever the case was, the conversion of a respiration system into a photosynthetic system is considered to have only happened , and all photosynthesizers descended from that original innovation.

About the time that the continents began to grow and began, Earth produced its first known glaciers, between 3.0 and 2.9 bya, although the full extent is unknown. It might have been an ice age or merely some mountain glaciation. The , and numerous competing hypotheses try to explain what produced them. Because the evidence is relatively thin, there is also controversy about the extent of Earth's ice ages. About 2.5 bya, the Sun was probably a little smaller and only about as bright as it is today, and Earth would have been a block of ice if not for the atmosphere’s carbon dioxide and methane that absorbed electromagnetic radiation, particularly in the . But life may well have been involved, particularly oxygenic photosynthesis, and it was almost certainly involved in Earth's first great ice age, which may have been a episode, and some pertinent dynamics follow.

The high oxygen levels may have turned pyrite on the continents into acid, which increased erosion, flooded essential nutrients, particularly phosphorus, into the oceans, and would have facilitated a huge bloom in the oceans. But this also happened in the midst of Earth's first ice age, so increased glacial erosion may have been primarily responsible, as we will see with a . The two largest carbon-isotope excursions () in Earth's history are related to ice ages. The first was a positive excursion (more carbon-13 than expected), and the second was negative. Scientists are still trying to determine what caused them. Beginning a little less than 2.3 bya and lasting for more than 200 million years is the Lomagundi excursion, in which there was great carbon burial. When the Lomagundi excursion finished, oxygen levels seem to have crashed back down to almost nothing and may have stayed that way for 200 million years, before rebounding to a few percent, at most, of Earth's atmosphere, and it stayed around that low level for more than a billion years.

David Brin, a careful thinker on the Fermi paradox and author of the first broad review the topic (1983) notes that Biker Gangs and other groups on Earth are cheerfully happy to contravene any social standard, and they are a good analogy for why the transcension hypothesis could never hold in every case.

This chapter will provide a somewhat detailed review of the Cryogenian Ice Age and its aftermath, including some of the hypotheses regarding it, evidence for it, and its outcomes, as the eon of complex life arose after it. The ran from about 850 mya to 635 mya. This review will sketch the complex interactions of life and geophysical processes, and the increasingly multidisciplinary methods being used to investigate such events, which are yielding new and important insights.

What are the hypothesis of which fruit produces the most electricity?

When investigating how ice ages begin and end, and feedbacks are considered. A positive feedback will accentuate a dynamic and a negative feedback will mute it. In the 1970s, and the author of today’s , , , which posits that Earth has provided feedbacks that maintain environmental . Under that hypothesis, environmental variables such as atmospheric and levels, levels, and Earth’s surface temperature have been kept relatively constant by a combination of geophysical, geochemical, and life processes, which have maintained Earth’s inhabitability. The homeostatic dynamics were mainly negative feedbacks. If positive feedbacks dominate, then “runaway” conditions happen. In astrophysics, are responsible for a wide range of phenomena. A runaway greenhouse effect may be responsible for . Climate scientists today are concerned that burning the hydrocarbons that fuel the industrial age . Mass extinctions are the result of Earth's becoming largely uninhabitable by the organisms existing during the extinction event. The ecosystems then collapse Mass extinction specialist recently proposed his as a direct challenge to the Gaia hypothesis.

This chapter presents several energy and chemistry concepts essential to this essay. Even though scientists do not really know what energy (they do not know what light or gravity , either), energy is perhaps best seen as motion, whether it is a photon flying through space, the "orbit" of an electron around an atom's nucleus or of Earth around the Sun, an object falling to Earth, a river flowing toward the ocean, air moving through Earth's atmosphere, rising and falling tides, and blood moving through a heart.
