ATLAS'S BURDENS (updated)

by L. Berney

If Atlas, who in Greek mythology carries the weight of the world on his shoulders,

was asked, "What are the world's weightiest problems today?" his answer would
probably include:


NEEDS OF THE POPULATION EXPLOSION The world population is set to
increase by some 50% or another 3,000 Million people in the next 50
years. All these extra people will need food, water, housing, clothing,
health care, education and the other necessities of life, and, of course,
jobs.

WATER SHORTAGE Already acute in some parts of the world -- the
increase in population will greatly increase this problem. Water shortage
can lead to conflict and even war.

POWER SUPPLY Raising the living standards of the developing world and
at the same time the increase in the world's population will consume a
vastly increased amount of power. An extrapolation of the year on year
increase in the world's power consumption shows that by 2050 the
consumption will have doubled; by the end of the century the power
required will be at least five times the present level.

THE END OF OIL AND GAS The world's need for energy is increasing
while the reserves of oil and gas are rapidly running out. As evidence, the
prices of oil and gas have doubled in recent years. Supplies must eventually
be exhausted, what then?

REDUCING CARBON DIOXIDE EMISSIONS. CO2 (almost certainly) causes
global warming and therefore climate change. As oil and gas become
scarcer and more expensive, the world will probably burn more coal, of
which there are is a vast reserve. Coal produces much more CO2 than oil
or gas and therefore increases global warming and all the dire
consequences which must follow.

RISING SEA LEVEL Due to global warming and melting ice, the sea level is
predicted to rise by up to one meter by the end of the century. If so, this
will inundate some of the most densely populated cities and areas in the
world. Hundreds of millions of people now in those cities and areas will
gradually re-locate in other, higher, areas.

CONSEQUENCES OF A CHANGE IN CLIMATE Climate change will cause
major changes in the amount and location of rainfall. Some parts of the
world will become virtually uninhabitable. The existing population in those
regions (many hundreds of millions) will over time have to re-locate in other
areas, and add to those of the hundreds of millions having to migrate due
to the rising sea level.

POVERTY Some 40%, or 2,700 Million, of the world's population are
currently having to live on less than US$2 (œ1) a day. Some 800 Million go
to bed hungry every night. Over 2,000 Million people have no access to
electricity. Poverty shortens life, causes disease, increases infant mortality,
leads to mass economic migration, more "illegal immigrants".

AIDS This pandemic, first recognized in 1981, had by 2006 caused the
death of some 25 million people. It is estimated that today some 39 million
people are infected, of these. nearly 600,000 are children. Although there
are treatments (for those that can afford them) which prolong life, there is
no known cure.

RELIGIOUS AMBITION -- WORLD DOMINATION Some religions dictate that it is
their holy duty to convert all non-believers and those individuals who will not convert must be dominated or killed. Such conflict has been waged for over 1,000 years and continues to this day.

---

What are the world's governments and commercial and industrial corporations
doing to tackle these global problems? From what I can discover, with one
exception, not much!

There has been a marked recent interest in the field of REDUCING CARBON
DIOXIDE EMISSIONS. The emphasis seems to be on RESTRICTING the use of
electricity and the use of vehicles by means of taxation and legislation (Kyoto, EU
and G8 resolutions). There is little or no emphasis on REPLACEMENT of the CO2
emitting fossil fuels by a non-polluting energy supply; no plans to increase the
energy supply to carry the world economy forward. In my opinion, the measures
being initiated to cut back on CO2 emissions are futile; they will inevitably fail to
result in any significant reduction. Example -- recently both China and India have
publicly stated that they have no intention of jeopardizing their economic
development in order to reduce their CO2 emissions! What is certain, however, is
that if the planned restrictions of CO2 emissions were, in fact, to be enforced
there is a very real danger of bringing about a world-wide economic recession.

In my view, we are heading in the wrong direction!

Again, in my view, there is another way, another direction. That way is the
harnessing of the inexhaustible supply of heat below the earth's surface,
GEOTHERMAL ENERGY. I believe the harnessing of geothermal energy would go
a long way towards resolving, or at least mitigating the effects of not only global
warming but most of the world's problems as well. Referring to Atlas's burdens
above, this is how.

The needs of the population explosion (about 50% in the next 50 years) can
be met given cheap and abundant electrical power.

The world's water shortage can be eliminated, given enough de-salination
plants; de-salination plants need electrical power.

The end of our reserves of oil, gas, and eventually coal, would not matter,
given an alternative source of energy, namely geothermal energy.

The introduction of geothermal energy could enable the use of all fossil fuels,
and the CO2 emissions they create, to be phased out over the next three or
four decades (possible exception: kerosene for aircraft, by comparison a very
small proportion of current fossil fuel consumption).

The problems of nuclear energy, the problem of the disposal of nuclear waste and
the danger of sabotage, could be eliminated by replacing nuclear with geothermal.

The world's annual increase in power requirement -- possibly five times by the
year 2100 -- could be met by geothermal energy; the heat below our feet is
unlimited.

The massive population re-location which climate change and sea level rise
will cause could be managed over time given an adequate supply of cheap
electrical power.

If we are to lift a quarter of the world's population out of poverty, provision of
electrical power is a basic essential -- there is no way it could be done
without electricity being available to people wherever they live.

While cheap power in itself will not eliminate the problem of Aids, treatment and
drugs for the millions now effected must depend on medical infrastructure and
education; both in turn requiring electrical power.

Even the world's problem with Islam and its militants would be reduced: the
interference (as Muslims see it) by the West in the affairs of the Islamic
countries stems very largely from the West's need for oil and gas, much of
which lies in Islamic countries. If the West no longer had need of Middle East
oil and gas there is no doubt that the conflict between Islam and the West
would be lessened.

Geothermal energy is pollution-free, environmental friendly, needs no
transportation or storage, is universally available in every region of the globe,
eliminates the political problems associated with fossil fuels between "have" and
"have not" countries, is inexhaustible and unending. But is unlimited geothermal
energy really available? Could it really be mined and used to generate electrical
power? Could it really replace fossil fuels and nuclear?

Last year the Massachusetts Institute of Technology produced a 300 page report
entitled "The Future of Geothermal Energy -- the impact of Enhanced Geothermal
Systems on the United States in the 21st. Century". In the Findings, the report
states, "Using reasonable assumptions regarding how heat would be mined (from
within the USA), we estimate the extractable portion to exceed about 2,000
times the annual consumption of primary energy in the United States in 2005.
Surely an amazing statement! And in principle surely true of regions in the rest of
the world as well.

In Hunter Valley, Australia, a pilot geothermal "hot rock" plant is in operation, see
. The company forecasts that the energy available
from their one site is more than sufficient to supply the electrical power required
by the whole of Australia for the foreseeable future.

If the manpower and global resources expended in the last two decades on wind
farms, solar panels and currently being expended on new wells to mine oil and
gas from less and less productive areas had instead been, and from now on would
be, used to develop geothermal heat as our basic energy source, we would be
well on the way to a permanent and ideal solution to the world's energy source
needs for the 21st. century.

I have been watching the pronouncements being made by the world's political,
commercial and scientific leaders. Hardly a day passes without the subjects of
global warming, climate change, greenhouse gas emissions, cutting back on CO2,
carbon trading, and the like, hitting the news. It is amazing, given the fact that
geothermal energy as an energy source is, (in my view) the near-perfect answer
to so many of the world's problems, that it is hardly ever mentioned!

Why not, one asks? I wish I knew!

Hot Fractured Rock Geothermal Energy - the Answer to Global Warming?

Energy is, and will remain, the largest business on Earth. This industry is undergoing major changes as the world grapples with climate change, pollution and the need for renewable energy. One source of renewable energy is hot fractured rock (HFR) geothermal energy.

HFR geothermal energy is produced using heat extracted from buried hot granites by circulating water through an engineered, artificial reservoir or underground heat exchanger. These hot granites represent a massive source of renewable energy, free from CO2 emissions.
The development of HFR geothermal energy relies on existing technologies. HFR geothermal projects are currently underway in France, Switzerland, Germany, California, and Japan. Australia has a recognised potential for the development of HFR geothermal energy.
Perhaps HFR is the answer to the world's future energy needs - a source that does not exacerbate the problem of global warming, is safe and seemingly available in infinite supply. This report entitled, "The Future of Geothermal Energy" suggests that the amount of extractable HFR energy exceeds the world's current consumption by a factor of several thousand!

To quote Sheikh Yamani: "The Stone Age did not end because people ran out of stones - it ended because they found something better."

According to Wikipedia, there are currently 27 wars taking place around the world.

There has been a marked recent interest in the field of REDUCING CARBON DIOXIDE EMISSIONS.

Moreover, if the measures being planned are actually enforced there is a very real danger of their causing a world-wide economic recession. We are, in my opinion, going in the wrong direction!

In my opinion again, the solution to this CO2 emission problem lies in the harnessing of the inexhaustible supply of heat below the earth's surface, GEOTHERMAL ENERGY, leading eventually to the complete elimination of the use of fossil fuels. Moreover this pollution-free, universally available, unlimited energy source would enable cheap and abundant electrical power to be available world-wide; this would go a long way towards solving, or at least adapting to, most of the world's problems.

If the global resources expended in the last two decades on wind farms, solar panels and on new wells to mine oil and gas from less and less productive areas had instead been used to develop geothermal heat as an energy source, we would be well on the way to a permanent and ideal solution to the world's energy source needs for the foreseeable future.

A Fact Sheet on Geothermal Energy follows.

GEOTHERMAL ENERGY FACT SHEET

INTRODUCTION

The word geothermal comes from the Greek words "geo" (earth) and "therme" (heat), and means the heat of the earth. Earth's interior heat originated from its fiery consolidation from dust and gas over 4 billion years ago and is continually regenerated from the decay of radioactive elements that occur in all rocks.

EARTH'S HEAT AND VOLCANIC REGIONS

It is almost 6,500 kilometres (4,000 miles) from the surface to the centre of the Earth, and the deeper you go, the hotter it gets.

The outer layer, the crust, is three to 35 miles thick and insulates us from the hot interior. From the surface down through the crust the normal temperature gradient (the increase of temperature with the increase of depth) in the Earth's crust is 17 - 30°C per kilometre of depth (50-87°F per mile). Below the crust is the mantle, made of highly viscous, partially molten rock with temperatures between 650 and 1,250°C (1,200-2,280°F). At Earth's core, which consists of a liquid outer core and a solid inner core, temperatures may reach 4,000-7,000°C (7,200 to 12,600°F). Where magma reaches the surface it can build volcanoes. But most magma stays well below ground, creating huge subterranean regions of hot rock sometimes underlying areas as large as an entire mountain range. Cooling can take from 5,000 to more than 1 million years. These shallow regions of relatively elevated crustal heat have high temperature gradients.

RENEWABILITY AND SUSTAINABILITY

Production from individual geothermal fields can be sustained for decades and perhaps centuries. The U.S. Department of Energy classifies geothermal energy as renewable.

GEOTHERMAL TECHNOLOGY AND EQUIPMENT

The drill rigs and drilling technology and equipment are virtually the same as that used for drilling for oil or gas. The electrical generating plant, located alongside the geothermal well heads, is standard; steam turbine driven electrical generators connected to the grid. Water consumption is small as the steam is condensed and re-used as injection water.

PROTECTION OF THE ENVIRONMENT

With all sources of energy, developers and consumers must work to protect the environment. The challenges differ with the type of energy resource, and the differences give geothermal energy certain advantages. Geothermal direct use facilities have minimal or no negative impacts on the environment. Geothermal power plants are relatively easy on the environment. They are successfully operated in the middle of crops, in sensitive desert environments and in forested recreation areas.

VISUAL PROTECTION

No power plant or drill rig is as lovely as a natural landscape, so smaller is better. A geothermal plant sits right on top of its fuel source: no additional land is needed such as for mining coal or for transporting oil or gas. When geothermal power plants and drill rigs are located in scenic areas, mitigation measures are implemented to reduce intrusion on the visual landscape. Some geothermal power plants use special air cooling technology which eliminates even the plumes of water vapour from cooling towers and reduces a plant profile to as little as 24 feet in height.

IMPROVING GEOTHERMAL TECHNOLOGY

Since the 1970's the geothermal industry, with the assistance of government research funding, has overcome many technical drilling and power plant problems. As a result of government-assisted research and industry experience, the cost of generating geothermal power has decreased by 25% over the past two decades. Research is currently underway to further improve exploration, drilling, reservoir, power plant and environmental technologies. Enhancing the recoverability of Earth's heat is an important area of ongoing research.

ENHANCED GEOTHERMAL SYSTEMS

Private and government research projects in the United States, Japan and in Europe are improving the accessibility of geothermal energy by developing new technology to increase the permeability of the rocks.

Permeability can be created in hot rocks by hydraulic fracturing -- injecting large volumes of water into a well at a pressure high enough to break the rocks. The artificial fracture system is mapped by seismic methods as it forms, and a second well is drilled to intersect the fracture system. Cold water can then be pumped down one well and hot water taken from the second well for use in a geothermal plant. This "hot dry rock" technology is being tested in Japan, Germany, France, England and the U.S. In Australia a test plant has been in operation for some time yielding excellent results.

THE FUTURE FOR GEOTHERMAL ENERGY

The outlook for geothermal energy use depends on at least three factors: the demand for energy in general; the inventory of available geothermal resources; and the competitive position of geothermal among other energy sources. The Demand for energy will continue to grow. Economies are expanding, populations are increasing (over 2 billion people still do not have electricity), and energy-intensive technologies are spreading. All these mean greater demand for energy. At the same time, there is growing global recognition of the environmental impacts of energy production and use from fossil fuel and nuclear resources. Public polls repeatedly show that most people prefer a policy of support for renewable energy.

The critical temperature for the generation of geothermal energy to power an electrical generating plant is 200ªC. At every point in the world a well will reach rock at that temperature; on average the depth to reach a temperature of 200ªC is about 5Km. Geothermal heat is more accessible in some areas than others but the inventory of accessible geothermal energy is sizable. The entire world resource base of readily accessible geothermal energy has been calculated in government surveys to be much larger than the resource bases of coal, oil, gas and uranium combined. The geothermal resource base becomes more available as methods and technologies for accessing it are improved through research and experience.

COSTS

Shorter and Longer Term Costs. Production of fossil fuels (oil, natural gas and coal) are a relative bargain in the short term. Like many renewable resources, geothermal resources need relatively high initial investments to access the heat. But the geothermal "fuel" cost is predictable and stable. Fossil fuel supplies will increase in cost as reserves are exhausted. Fossil fuel supplies can be interrupted by political disputes abroad.

Renewable geothermal energy is a better long term investment.

Direct and Indirect Costs. The monetary price we pay to our natural gas and electricity suppliers, and at the gas pump, is our direct cost for the energy we use. But the use of energy also has indirect or external costs that are imposed on society.

Examples are the huge costs of global climate change; the health effects from ground level pollution of the air; future effects of pollution of water and land; military expenditures to protect petroleum sources and supply routes; and costs of safely storing radioactive waste for generations. Geothermal energy can already compete with the direct costs of conventional fuels in some locations and is a clean, indigenous, renewable resource without hidden external costs. Public polls reveal that customers are willing to pay a little more for energy from renewable resources such as geothermal energy.

Domestic and Importing Costs. Investment in the use of domestic, indigenous, renewable energy resources like geothermal energy provides jobs, expands the regional and national economies, and avoids the export of money to import fuels.

Energy demand is increasing rapidly worldwide. Some energy and environmental experts predict that the growth of electricity production and direct uses of geothermal energy will be revitalized by international commitments to reduce carbon dioxide emissions to avert global climate change.
