alternative energy sources pdf

The fourth, fifth and sixth chapters are expositions of fission and fusion nuclear energy. The
following five chapters (seventh to eleventh) include detailed descriptions of the most common renewable energy sources—wind, solar, geothermal, biomass, hydroelectric—and some of the less common sources, such as tidal and wave energy.

The emphasis of these chapters is on the global potential of each source;
the engineering/technical systems that are currently used in harnessing the
potential of each one of these energy sources; the technological developments that
will contribute to wider utilization of the sources; and the environmental effects
associated with their current and their wider use.

The last three chapters are:
energy storage, which is the main limitation of the wider use of solar and wind
power and will become an important issue if renewable energy sources are to be
used widely; energy conservation, which appears to be everyone’s favorite issue,
but by itself is not a solution to our energy challenge; and energy economics,
a necessary consideration in market-driven economies.

A number of individuals have helped in the writing of this book: first among
them are the students who took my course on Alternative Energy. I have learned
from them and their questions more than they have learned in my classes. Two of
these students contributed significantly to the writing of the book: Maria
Andersson reviewed several chapters and gave me valuable suggestions. Eric
Stewart drew some of the figures.
