Life has evolved on Earth with electromagnetic radiation (light), fermentable organic molecules, and oxidizable chemicals as sources of energy. Biological use of thermal energy has not been observed although heat, and the thermal gradients required to convert it into free energy, are ubiquitous and were even more abundant at the time of the origin of life on Earth. Nevertheless, Earth-organisms sense thermal energy, and in suitable environments may have gained the capability to use it as energy… 
Energy Sources and Life
An external energy source is a necessary condition for life, because living systems require a flow of energy to organize materials and maintain a low state of entropy (Morowitz 1968). Energy is also

The hypothesis is proposed that during the organization of pre-biotic bacterial cell(s), high-energy electrical discharges, infrared radiation (IR), thermosynthesis and possibly pre-photosynthesis
The prospect of alien life in exotic forms on other worlds
TLDR
A detailed discussion of two possible habitats for alien life which are generally not considered as such: the lower cloud level of the Venusian atmosphere and Titan’s surface environment are provided.
Energy Production and the Potential for Life on Outer Solar System Satellites
Scientists searching for extraterrestrial life forms have recently begun to focus their attention on a group of icy bodies in the outer solar system. These satellites, particularly Europa, Enceladus,
Energy Sources for, and Detectability of, Life on Extrasolar Planets
Life in the accessible biosphere on Earth today is energised in primary productivity mainly by solar radiation through photolithotrophy with a minor role for chemolithotrophy based on reductants from
Energy Sources, Self-organization, and the Origin of Life
TLDR
The emergence and early developments of life are considered from the point of view that contingent events that inevitably marked evolution were accompanied by deterministic driving forces governing the selection between different alternatives, and a direct connection between the free energy content of intermediates of early pathways and the quanta of energy delivered by available sources of energy is suggested.
The Astrobiology of Alien Worlds: Known and Unknown Forms of Life
Most definitions of life assume that, at a minimum, life is a physical form of matter distinct from its environment at a lower state of entropy than its surroundings, using energy from the
The Power Without the Glory: Multiple Roles of Hydrogen Peroxide in Mediating the Origin of Life.
TLDR
The HP crucible hypothesis is radical, but based on well-known chemistry and physics, it is eminently testable in the laboratory, and many of the simulations provide recipes for such experiments.
The landscape of life
Earth is a planet that exhibits an immense biomass and an incredible biodiversity. Yet, the question arises as to whether the diversity as observed on Earth reflects the limits of life or whether

Energy cycling and hypothetical organisms in Europa's ocean.
TLDR
Using reasonable assumptions based on known organisms on Earth, these calculations suggest that chemical oxidation-reduction cycles in Europa's subsurface ocean could support life.
Finding extraterrestrial organisms living on thermosynthesis.
TLDR
A general strategy for detecting thermosynthetic organisms on Earth is offered, and highlights of current and upcoming robotic exploratory missions relevant to the detection of thermosynthesis are reviewed.
The habitat and nature of early life
TLDR
It is possible that early life diversified near hydrothermal vents, but hypotheses that life first occupied other pre-bottleneck habitats are tenable (including transfer from Mars on ejecta from impacts there).

The emergence of life from iron monosulphide bubbles at a submarine hydrothermal redox and pH front
TLDR
The hypothesis is that the FeS membrane, laced with nickel, acted as a semipermeable catalytic boundary between the two fluids, encouraging synthesis of organic anions by hydrogenation and carboxylation of hydrothermal organic primers, and led to the miniaturization of the metabolizing system.

TLDR
A theoretical mechanism allowing biomembranes to convert heat into electrical energy during temperature cycling (thermosynthesis) is described and its possible value compared with the power of respiration is discussed.
Thermodynamics of the primary and secondary photochemical reactions in Chromatium.
TLDR
Thermodynamic properties of the primary and secondary photosynthetic electron transfer reactions in Chromatium vinosum have been studied with the aid of short actinic light flashes, and values of ΔG °, ΔH °, and ΔS ° derived from redox titrations of the electron carriers in separate photosynthesis units probably represent the true standard state values for the photochemical reactions.

TLDR
A hierarchical mission design is envisioned that includes spaceborne (orbital), atmosphere, surface, and subsurface agents working in concert to allow for sufficient mission safety and redundancy, to perform extensive and challenging reconnaissance, and to lead to a thorough search for evidence of life and habitability.
