Energy availability
Introduction
Advancement in civilization and science can be attributed to the availability of energy. Over the past years, energy has been the driving force behind various sectors of the economy, such as transport, manufacturing and processing, agriculture, etc. Great scientific explorations have also been enabled by the progress made in energy production systems that power space vehicles and satellites. Owing to its importance, human beings have always, both in the past and in the present times, sought for methods of exploiting energy resources to obtain maximum benefits. The increased use of coal during the industrial revolution enhanced industrial growth and mechanization in the production of goods. Coal exploitation also changed the transport sector with invention of locomotives and steam powered engines that required coal. Advancement in technology led to exploitation of petroleum, thereby replacing coal as the main source of energy. Petroleum has been widely used in power generators and as fuel for engines. Concerns have however been raised on the durability of the available energy resources since most coal and petroleum deposits are getting depleted and may not be available in the future [3]. This has led to research and development on alternative energy sources such as solar, wind, hydro, geothermal and even tidal energy. In addition, the use of various forms of energy in homes, places of work and industries has undergone major transformations in a bid to minimize energy wastage and lower pollution levels arising from the production of greenhouse gasses. Scientists have also come up with methods of making the use of energy more convenient and reliable. More power stations are also being built in an attempt to meet the ever growing power demands by the human population. All these efforts are driven by the concern that the world.
Introduction to energy sources & its conversionAshish993218
Measure of the ability of a body or system to do work or produce a change, expressed usually
in joules or kilowatt hours (kWh). No activity is possible without energy and its total amount in the
universe is fixed. In other words, it cannot be created or destroyed but can only be changed from one
type to another.
Resource refers to all the materials available in our environment which help us to satisfy our needs and wants. It is technologically accessible, economically feasible and culturally acceptable.
Resources are characterized as renewable or nonrenewable.
A renewable energy source means energy that is sustainable - something that can't run out, or is endless, like the sun.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

Slide 2: Introduction to Extrachromosomal Inheritance
Definition: Extrachromosomal inheritance refers to the transmission of genetic material that is not found within the nucleus.
Key Components: Involves genes located in mitochondria, chloroplasts, and plasmids.
Slide 3: Mitochondrial Inheritance
Mitochondria: Organelles responsible for energy production.
Mitochondrial DNA (mtDNA): Circular DNA molecule found in mitochondria.
Inheritance Pattern: Maternally inherited, meaning it is passed from mothers to all their offspring.
Diseases: Examples include Leber’s hereditary optic neuropathy (LHON) and mitochondrial myopathy.
Slide 4: Chloroplast Inheritance
Chloroplasts: Organelles responsible for photosynthesis in plants.
Chloroplast DNA (cpDNA): Circular DNA molecule found in chloroplasts.
Inheritance Pattern: Often maternally inherited in most plants, but can vary in some species.
Examples: Variegation in plants, where leaf color patterns are determined by chloroplast DNA.
Slide 5: Plasmid Inheritance
Plasmids: Small, circular DNA molecules found in bacteria and some eukaryotes.
Features: Can carry antibiotic resistance genes and can be transferred between cells through processes like conjugation.
Significance: Important in biotechnology for gene cloning and genetic engineering.
Slide 6: Mechanisms of Extrachromosomal Inheritance
Non-Mendelian Patterns: Do not follow Mendel’s laws of inheritance.
Cytoplasmic Segregation: During cell division, organelles like mitochondria and chloroplasts are randomly distributed to daughter cells.
Heteroplasmy: Presence of more than one type of organellar genome within a cell, leading to variation in expression.
Slide 7: Examples of Extrachromosomal Inheritance
Four O’clock Plant (Mirabilis jalapa): Shows variegated leaves due to different cpDNA in leaf cells.
Petite Mutants in Yeast: Result from mutations in mitochondrial DNA affecting respiration.
Slide 8: Importance of Extrachromosomal Inheritance
Evolution: Provides insight into the evolution of eukaryotic cells.
Medicine: Understanding mitochondrial inheritance helps in diagnosing and treating mitochondrial diseases.
Agriculture: Chloroplast inheritance can be used in plant breeding and genetic modification.
Slide 9: Recent Research and Advances
Gene Editing: Techniques like CRISPR-Cas9 are being used to edit mitochondrial and chloroplast DNA.
Therapies: Development of mitochondrial replacement therapy (MRT) for preventing mitochondrial diseases.
Slide 10: Conclusion
Summary: Extrachromosomal inheritance involves the transmission of genetic material outside the nucleus and plays a crucial role in genetics, medicine, and biotechnology.
Future Directions: Continued research and technological advancements hold promise for new treatments and applications.

different forms, such as potential, kinetic, thermal, electrical, chemical,
radioactive, etc. Additionally, there is heat and work, which is energy
being transferred from one body to another.

Renewable Energy
• Collected from renewable
resources that are naturally
replenished on a human
timescale.
• Examples: Solar energy,
Wind energy, Geothermal
energy, Tidal energy,
Biomass energy,
Hydroelectric energy.
Non-renewable Energy
• cannot be readily
replaced by natural.
• Examples: Petroleum,
Fossil fuel, Nuclear
energy.
6. Conservation vs Conversion
Conservation
Conversion
According to the rule of conservation of energy, the overall energy of an
isolated system stays constant throughout time. According to this law, which
Émile du Châtelet initially suggested and tested, energy can only be changed or
moved from one form to another and cannot be generated or destroyed.
The process of converting energy from one form to another is called energy
transformation or energy conversion. Energy is a substance that gives one the ability
to do labor (like lifting an object) or give off heat. Energy can be transferred to another
place or object in addition to being transformed, but it cannot be generated or
destroyed, in accordance with the rule of conservation of energy.

and are thus considered to be
renewable.
RENEWABLE
ENERGY
10. RENEWABLE ENERGY SOURCES
Solar Energy
Solar energy is harnessed
using two primary
methods.
Wind Energy
In wind turbines, the
kinetic energy of the wind
may be harnessed to
produce electricity.
Geothermal
This energy source is heat
released from the crust of
the earth, typically in the
form of hot water or steam
that may be utilized to turn
a turbine and produce
electricity.
11. Biomass
Any plant material burned
directly or transformed into
another form before
combustion, such as
wood, vegetable waste
like crop and wood waste,
and animal products and
wastes, is referred to as
biomass.
Tidal Energy
Similar to a wind turbine, a
tidal energy generator
uses a turbine with
revolving blades that
depend on the strength of
the tide. The generator,
which generates power, is
turned by the gearbox
attached to the turbine.
Hydroelectric
Energy
Water's potential and
kinetic energy are
converted into electricity to
produce it. This makes a
sizable contribution to
overall energy
consumption in emerging
nations.
