Renewable and Non-renewable assets
There is no denying the
fact that in Modern Economic theory, a non-renewable resource known
as a predetermined reserve is a resource that does not renovate itself at an
appropriate rate for supportable economic abstraction in expressive human
time-frames. We can introduce a model as carbon-based progressively resulting
fuel. The unique biological material, with the help of heat and pressure,
becomes a gasoline such as oil or gas, Fossil Fuel which may be considered as
coal, petroleum, and natural gas, are all non-renewable resources.
Metalores are supplementary examples of
non-renewable resources. The metals themselves are present-day in vast amounts
in the earth’s crust, and are constantly focused and refilled over millions of
years. However their extraction by humans only occurs where they are
concentrated by natural processes (such as heat, pressure, organic activity,
weathering and other processes) enough to become economically viable to
extract. These processes generally take from tens of thousands to millions of
years. As such, localized deposits of metal ores near the surface which can be
extracted economically by humans are non-renewable in human timeframes, but on
a world scale, metal ores as a whole are inexhaustible, because the amount
vastly exceeds human demand, on all timeframes. Though they are theoretically
non-renewable, just like with rocks and sand, humans could never deplete the
world’s supply. In this respect, metal ores are considered vastly greater in
supply to fossil fuels because metal ores are formed by crustal scale processes
which make up a much larger portion of the earth’s near-surface environment
than those that form fossil fuels, which are limited to areas where
carbon-based life forms flourish, die, and are quickly buried. These fossil
fuel-forming environments occurred lengthily in the Carboniferous Period.
In contrast, resources
such as timber (when harvested sustain-ably) and wind (used to power energy conversion systems) are
considered renewable
resources, largely because their localized replenishment can occur
within timeframes meaningful to humans.
Non-renewable assets are:
1 Fossil fuel
2 Radioactive
fuel
3 Renewable
resources
4 Economic
models
Natural resources such
as coal, petroleum (crude oil)
and natural gas take
thousands of years to form naturally and cannot be replaced as fast as they are
being consumed. Eventually it is considered that fossil-based resources will
become too costly to harvest and humanity will need to shift its reliance to
other sources of energy. These resources are yet to be named.
An alternative hypothesis
is that carbon based fuel is virtually inexhaustible in human terms, if one
includes all sources of carbon-based energy such as methane hydrates on the sea
floor, which are vastly greater than all other carbon based fossil fuel
resources combined. These sources of carbon are also considered non-renewable,
although their rate of formation/replenishment on the sea floor is not known.
However their extraction at economically viable costs and rates has yet to be
determined.
At present, the main
energy source used by humans is non-renewable fossil fuels. Since the dawn
of internal
combustion engine technologies in the 17th century, petroleum
and other fossil fuels have remained in continual demand. As a result,
conventional infrastructure and transport systems,
which are fitted to combustion engines, remain prominent throughout the globe.
The continual use of fossil fuels at the current rate is believed to
increase global warming and
cause more severe climate change.
Renewable resources
Natural resources, called
renewable resources, are replaced by natural processes and forces persistent
in the natural
environment. There are intermittent and
reoccurring renewable, and recyclable
materials, which are utilized during a cycle across
a certain amount of time, and can be harnessed for any number of cycles.
The production of goods
and services by manufacturing products in economic systems creates
many types of waste during
production and after the consumer has
made use of it. The material is then either incinerated, buried in
a landfill or recycled
for reuse. Recycling turns materials of value that would otherwise become waste
into valuable resources again.
The natural environment,
with soil, water, forests, plants and animals are all
renewable resources, as long as they are adequately monitored,
protected and conserved. Sustainable
agriculture is the cultivation of plant materials in a manner
that preserves plant and animal ecosystems over the
long term. The over-fishing of
the oceans is one example of where an industry practice or method can threaten
an ecosystem, endanger species and possibly
even determine whether or not a fishery is
sustainable for use by humans. An unregulated industry practice or method can
lead to a complete resource depletion.
The renewable energy from
the sun, wind, wave, biomass and geothermal energies
are based on renewable resources. Renewable resources such as the movement
of water (hydropower, tidal power and wave power), wind and radiant energy from
geothermal heat (used for geothermal power) and
solar energy (used for solar power)
are practically infinite and cannot be depleted, unlike their non-renewable
counterparts, which are likely to run out if not used sparingly.
The potential wave energy
on coastlines can provide 1/5 of world demand. Hydroelectric power can supply
1/3 of our total energy global needs. Geothermal energy can provide 1.5 more
times the energy we need. There is enough wind to power the planet 30 times
over, wind power could power all of humanity’s needs alone. Solar currently
supplies only 0.1% of our world energy needs, but there is enough out there to
power humanity’s needs 4,000 times over, the entire global projected energy
demand by 2020.
Renewable energy
and energy
efficiency are no longer niche sectors that are
promoted only by governments and environmentalists. The increasing levels of
investment and that more of the capital is from conventional financial actors,
both suggest that sustainable energy has become mainstream and the future of
energy production, as non-renewable resources decline. This is reinforced
by change concerns, nuclear dangers and accumulating radioactive
waste, high oil prices, peak oil and
increasing government support for renewable energy. These factors are commercializing
renewable energy, enlarging the market and growing demand, the
adoption of new products to replace obsolete technology and the conversion of
existing infrastructure to a renewable standard.
In economics, a
non-renewable resource is defined as goods, where greater
consumption today implies less consumption tomorrow. David Ricardo in his
early works analyzed the pricing of exhaustible resources, where he argued that
the price of a mineral resource should increase over time. He argued that the
spot price is always determined by the mine with the highest cost of
extraction, and mine owners with lower extraction costs benefit from a
differential rent. The first model is defined by Hotel ling’s rule, which
is a 1931 economic model of non-renewable resource management by Harold Hotelling. It shows
that efficient exploitation of a nonrenewable and non-augment able resource
would, under otherwise stable conditions, lead to a depletion of the
resource. The rule states that this would lead to a net price or “Hotelling rent” for it
that rose annually at a rate equal to the rate of interest,
reflecting the increasing scarcity of the resources. The Hart-wick’s rule provides an
important result about the sustainability of
welfare in an economy that uses non-renewable source.
However, nearly all metal
prices have been declining over time in inflation adjusted terms, because of a
number of false assumptions in the above. Firstly, metal resources are
non-renewable, but on a world scale, largely inexhaustible. This is because
they are present throughout the earth’s crust on a vast scale, far exceeding
human demand on all time scales. Metal ores however, are only extracted in
those areas where nature has concentrated the metal in the crust to a level
whereby it is locally economic to extract. This also depends on the available
technology for both finding the metal ores as well as extracting them, which is
constantly changing. If the technology or demand changes, vast amounts of metal
previously ignored can become economically ex tractable. This is why Ricardo’s
simplistic notion that the price of a mineral resource should increase over
time has in fact turned out to be the opposite, nearly all metal ores have
decreased in inflation adjusted prices since well before the early 20th
century. The main reason he was wrong is that he assumed that metals are
exhaustible on a world scale, and he also misunderstood the effect of globally
competing markets; in human terms the amount of metal in the earth’s crust is
essentially limitless. It is only in localized areas that metal ores can become
depleted, as these local areas compete with extraction an cost of resources
elsewhere, which does have ramifications for the sustainability of local
economies.
A renewable resource is
a natural resource which
can replenish with the passage of time, either through biological reproduction
or other naturally recurring processes. Renewable resources are a part of Earth‘s natural environment and
the largest components of its exosphere. A
positive life cycle
assessment is a key indicator of a resource’s sustainability. In
1962, Paul Alfred
Weiss defined Renewable Resources as: “The total range of
living organisms providing man with food, fibers, drugs, etc…”
Renewable resources may
be the source of power for renewable energy. However,
if the rate at which the renewable resource is consumed exceeds its renewal
rate, renewal and sustainability will not be ensured.
