Earthmovers are huge because they were created to dig deep holes and to prepare land for new buildings and roadways. Construction companies often use them. With their large machinery and loud growls, earthmovers are hard to miss. There are different kinds of earthmovers, each built for a specific task, but they are all created to get big jobs done fast. Informative text and full-color photographs will delight budding engineers and machine enthusiasts.

Energy is at the top of the list of environmental problems facing industrial society, and is arguably the one that has been handled least successfully, in part because politicians and the public do not understand the physical technologies, while the engineers and industrialists do not understand the societal forces in which they operate. In this book, Allan Mazur, an engineer and a sociologist, explains energy technologies for nontechnical readers and analyses the sociology of energy. The book gives an overview of energy policy in industrialised countries including analysis of climate change, the development of electricity, forms of renewable energy and public perception of the issues. Energy is a key component to environment policy and to the workings of industrial society. This novel approach to energy technology and policy makes the book an invaluable inter-disciplinary resource for students across a range of subjects, from environmental and engineering policy, to energy technology, public administration, and environmental sociology and economics.
