Everyday, the world produces carbon dioxide that is released
into the Earth's atmosphere. This increase in carbon dioxide
content is responsible for a rise in the temperature of our
planet and contributes to what is known as "Global Warming".
One answer to global warming is to replace and retrofit
current technologies with alternative ones, which are of
comparable or greater efficiency but do not release carbon
dioxide.
We call this Alternate energy. Climate change,
population growth and fossil fuel depletion imply that
renewables will need to play a bigger role in the future than
they do today. According to British Petroleum and Royal
Dutch Shell, two of the world's largest oil companies, onethird
of the world's energy will need to corne from solar, wind, and
other renewable resources by 2050. Alternative energy refers
to energy sources that have no undesirable consequences such
as those caused by fossil fuels or nuclear energy.
Alternative
energy sources are renewable and are thought to be «free».
Compared to conventional energy sources, they all release less
carbon. They include solar energy, wind energy, geothermal
energy, fuel cell batteries and nuclear energy. This book
provides a comprehensive overview of the main types of
renewable energy. In addition, the text explains the underlying
physical and technological principles of renewable energy and
examines the environmental impact and future prospects of
different energy sources.
It includes over 350 detailed
illustrations, more than fifty tables of data, and a wide range of
case studies.
