Vietnam‟s hydro-power resources are very plentiful and distributed widespread in national
scope. Vietnam is one of 14 countries which are rich in hydro-electric resources in the world.
Total hydro-power resources potential of more than 2200 mini, medium and large rivers (just
mention rivers with more than 10 km in length) in national scope is assessed as follows:
Renewable energy is shifting from the fringe to the mainstream of sustainable
development. Past donor efforts achieved modest results but often were not
sustained or replicated, which leads now to greater market orientation. Markets for
rural household lighting with solar home systems, biogas, and small hydro power have
expanded through rural entrepreneurship, government programs, and donor assistance,
serving millions of households. Applications in agriculture, small industry, and social
services are emerging. Public programs resulted in 220 million improved biomass cook
The issue of energy conservation has been with us since the seventies and there has
not been a dearth of ideas and increase of knowledge arising from research from
various disciplines ever since. The importanceof energy conservation has been on the
increase that has resulted in the need toproduce books to introduce new and richer
findings and applications in this field.
This book comprises of nine chapters which cover several disciplines. Each chapter has
been carefully written by leading teams of experts from various parts of the world.
This book covers the areas of fundamentals in energy conservation and its applications in selected industries. There are nine chapters in this book which have been written by leading experts in energy from all over the world. The topics range from energy fundamentals from cosmic radiation, tidal waves and dams. The chapters examine the potential of utilizing energy from sustainable resources and how energy consumption may be conserved from various new technologies.
During the last two decades, increase in electricity demand and environmental
concern resulted in fast growth of power production from renewable sources. Wind
power is one of the most efficient alternatives. Due to rapid development of wind
turbine technology and increasing size of wind farms, wind power plays a significant
part in the power production in some countries.

On the Reliability of Real Measurement Data for Assessing Power Quality Disturbances
Alexandre Brandao Nassif
Hydro One Inc.,Toronto, ON, Canada
Power quality assessment is a power engineering field that is first and foremost driven by real data measurements. All the power quality assessment applications rely on results from real data processing.
Flow measurement is a basic tool in industry, engineering and research. The existing
applications reveal the evolution and development of new methods and devices
through the years. Some of the latest emerging technologies, such as microelectronics
and nanotechnology, have put forward new challenges in the flow measurement and
are treated at the beginning of this book.
This book comprises 8 chapters divided into 4 sections, starting with “microflows”,
followed by the “biphasic” and “gas flow”.
Recently, the resettlement activities of Son La hydroelectric power station (SHPS) have been carrying out within three provinces: Son La, Lai Chau, and Dien Bien. The main problem is !hat with limited land fund for resett1emcnt (each household has about 1-2 ha of agricultural land in average ), the land use and argicultural production organization should be ensure favorable conditions for resettled people.
1) Begin class in the dark today. If possible,
close blinds and turn off lights. Ask students
if they know where their electricity comes
from. Is it from a coal-fired power plant?
Hydro-electric? Wind energy? Is the plant
nearby? Have this discussion in the dark.
2) Turn on the lights and point out the ease
with which the room was supplied electricity.
Where does the power originate? Explain that
students will investigate this today in class.
The environmental goods and services (EGS) sector has traditionally included solutions for problems
such as air, noise and marine pollution, land and water contamination, as well as activities such as
environmental analysis and consultancy and waste management and recycling. However more
recently, the definition of this sector has widened.
Geoff Allan, Mark Booth, Jacob Wani and Wally Solata traveled to the Yonki Dam Research
Station at the conclusion of the feeds workshop to inspect a tilapia feeding experiment (i.e.
approximately 1 hour by road from the CRI) (ACIAR Mini-Project led by Cathy Hair). Several
other workshop participants that were traveling back to Lae also took the opportunity to visit the
Station (e.g. Greg Denn, Klaus & Tom Neumeier, Miok Komolong, Densly Tapat, Eric Nogas,
Johnney Soranzie & others). The Yonki Dam was created to drive a hydro-electric power scheme
providing electricity to much of PNG.
