This book investigates the role of gas networks in future
low-carbon energy systems, and discusses various decarbonisation
pathways, providing insights for gas network operators, developers,
and policy makers. As more countries around the world move towards
low-carbon energy systems and increase their exploitation of
renewable energy sources, the use of natural gas and the associated
infrastructure is expected to undergo a substantial transformation.
As such there is a great uncertainty regarding the future role of
gas networks and how they will be operated in coming years. The
topics addressed include: Fundamentals of gas network operation The
impact of variable renewable electricity generation on the
operation and expansion of gas networks The impact of decarbonising
heat supplies on gas networks Opportunities and challenges of
utilising gas networks to transport alternative low-carbon gases
such as bio-methane and hydrogen
Modern societies require energy systems to provide energy for
cooking, heating, transport, and materials processing, as well as
for electricity generation. Energy systems include the primary
fuel, its conversion, and transport to the point of use. In many
cases this primary fuel is still a fossil fuel, a one-use resource
derived from a finite supply within our planet, causing
considerable damage to the environment. After 300 years of
increasing reliance on fossil fuels, particularly coal, it is
becoming ever clearer that the present energy systems need to
change. In this Very Short Introduction Nick Jenkins explores our
historic investment in the exploitation of fossil energy resources
and their current importance, and discusses the implications of our
increasing rate of energy use. He considers the widespread
acceptance by scientists and policy makers that our energy systems
must reduce emissions of CO2 and other greenhouse gases, and looks
forward to the radical changes in fuel technology that will be
necessary to continue to provide energy supplies in a sustainable
manner, and extend access across the developing world. Considering
the impact of changing to an environmentally benign and low-carbon
energy system, Jenkins also looks at future low-carbon energy
systems which would use electricity from a variety of renewable
energy sources, as well as the role of nuclear power in our energy
use. ABOUT THE SERIES: The Very Short Introductions series from

"Speaker" is an unlovable thirty-something academic who spends his
time writing articles for the Internet encyclopaedia "Wikipedia."
While attempting mediation over a controversial article, Speaker is
drawn into the conflict over an article about the Venezuelan
president, Hugo Chavez. When one of the contributors, the beautiful
18 year old Aletheia, is found dead in her flat, Speaker is accused
of murder. In the attempt to clear his name he uncovers a
conspiracy between an FBI agent, a Columbian lawyer and elements of
the Venezuelan government. He confronts the man he suspects to be
the killer, his girlfriend is kidnapped, his closest friend is
murdered and he faces a choice between abandoning his pursuit of
truth or pushing through to the end at the peril of his own life.
Hari Singh, the pilot of the "Argonaut," a Daedalus class STL probe
awakes to find the ship is lost in space. He and his crew abandon
ship and land on an alien planet where they must fight for
survival. They manage to attract the attention of an advanced
starship and are rescued by the 'near-human' crew of the "Uhorr."
But their benefactors are not all they seem. In return for the
salvage of the "Argonaut," the captain of the "Uhorr" agrees to
transport the characters to a civilised world. As Hari and the
others strip the stricken "Argonaut," the "Uhorr's" crew turn on
them and murder eveyone but Hari and Tatiana, the ship's medic. In
the fight, Hari and Tatiana manage to seize control of the "Uhorr"
and kill the crew. Now they are lost in a strange universe, with a
faster than light spaceship at their disposal....

Yossarian, Archon of the fabled city-state of Sardis, loses his
love in death. Driven mad with grief he vows to descend to Hades
and return her to the land of the living. Reluctantly accompanied
by Sancho, his servant and companion, Yossarian seeks the aid of an
Oracle and is joined on the journey by two young companions.
Meanwhile Yossarian's brother, Marcos, plots to overthrow him and
seize the throne of Sardis for himself. As Yossarian ventures
through the desert, searching for the oasis of the Virgin's Tears
and the entrance to Hades, Marcos assassins catch up with him and
Yossarian faces battles in both the world of the living and the
world of the dead.
Throughout the world there is concern over the impact of energy use
on the environment (particularly CO2 emissions) and also over the
security of fossil fuel supplies. Consequently, governments and
energy planners are actively encouraging alternative and cleaner
forms of energy production such as renewables (e.g. wind, solar,
biomass) and combined heat and power (CHP). The economics and
locations of sustainable energy sources have meant that many of
these new generators are connected into distribution networks. It
is recognized that the information flow and control of distribution
networks is inadequate for these future low-carbon electricity
supply systems. The future distribution network will change its
operation from passive to active, and the distributed generators
will be controlled to support the operation of the power system. In
many countries this transformation of electricity supply is managed
through energy markets and privately owned, regulated transmission
and distribution systems. This book discusses the connection of
generation to distribution networks and then moves on to consider
how sustainable generation can be fully integrated into the
operation of the power system. Both technical and economic aspects
are addressed. It is written for later-year undergraduate and
postgraduate students studying courses on energy. The book has four
tutorial chapters (with examples and questions) to provide
fundamental material for those without a strong electrical
engineering background.
The rapid growth of wind generation has many implications for power
system planning, operation and control. This would have been a
considerable challenge for the old nationalised power companies; it
has become an even greater challenge in today's liberalised
electricity markets. Network development, voltage rise, protection,
monitoring and control are connection problems common to all wind
power generation. These issues are addressed through an
understanding of the basic electrical engineering concepts and wind
power technology. When wind power approaches 10 percent of all
generation, it impinges on system operation. The underlying
principles of system balancing are presented, before considering
the impact of many variable generation sources whose outputs are
difficult to predict. Wind power forecasting is crucial to
successful wind power integration, and basic theory and current
practice are considered. Storage can also help but it needs to be
low cost and, ideally, based on intelligent use of existing load.
Finally, electricity markets are explained and the commercial
challenges facing wind power are assessed. The book provides a
wide-ranging discussion on all major aspects of wind power
integration into electricity supply systems. It requires no
specialist knowledge and will appeal to engineers from various
disciplines looking for an overview of a technology that is
providing a major impetus for sustainable electricity supply in the
twenty-first century.
Is there only one possible outcome for the evolution of mankind?
When two cultures light years apart follow different evolutionary
paths, that question could be answered. And many more could be
raised. In the twenty-second century, Earth was dying. World
population was more than twenty billion, the global environment was
in ruins, and living conditions were intolerable everywhere on the
planet. Many people thought the only hope for mankind lay in
colonizing space. And so giant ships were built to carry brave
volunteers who would settle the planets of nearby stars. Many years
later, the colonists returned. The Earth they found was a far
different place than the Earth of their distant ancestors. And they
were not welcome.

The use of combined heat and power (CHP) plants and renewable
energy sources reduces the amount of greenhouse gases released into
the atmosphere and helps to alleviate the consequent climate
change. The policies of many governments suggest that the
proportion of electrical energy produced by these sources will
increase dramatically over the next two decades. Unlike traditional
generating units, these new types of power plant are usually
'embedded' in the distribution system or 'dispersed' around the
network. As a result, conventional design and operating practices
are no longer applicable; for example, power protection principles
have to be revised and complex economic questions need to be
resolved. This book, intended for both students and practising
engineers, addresses all the issues pertinent to the implementation
of embedded generation. Much of the material was originally
developed for the UMIST MSc/CPD course in Electrical Power
Engineering so there is a strong tutorial element. However, since
this subject is evolving very rapidly, the authors also discuss the
technical and commercial consequences of the very high penetration
of embedded generation that are to be expected in the years ahead.
