ONEWorld Publications Energy: A Beginner's Guide Paperback – Big Book, 5 January 2017

Livro muito bom para a proposta de ser um guia para iniciantes no tema. O tema energia é abordado em perspectiva temporal (passado, presente e tendências para o futuro) em setores e atividades mais importantes. Em geral, a leitura é agradável. Apesar do conteúdo ser conciso, os capítulos trazem dados e gráficos interessantes que podem ser consultados posteriormente, mas para isso o índice remissivo poderia ser mais extenso.

Vaclav Smil (the author) having already written so many books on subjects related to energy (ex. E. and civilization, or Prime movers, or Making the modern world), one may fear this book is only one more book by the same author on the same subject. However, I feel this book serves a useful purpose because it covers a larger variety of concerns about energy in a smaller volume than previous Smil's books (it almost fits in one's pocket). Covered concerns are the very concept of energy, the climate, its harnessing in history, its role in our modern world, and questions for our future. As usual with this author the book is abundantly documented, and it is laden with numbers, but as the author writes in another book "he will never apologize for that". Altogether, I recommend this book, at least for readers who have not already read Smil on that same subject.

Entender la energía en todas sus dimensiones no es una tarea únicamente de ingenieros. Cualquier esfuerzo humano requiere conocer los principios, las fuerzas y los elementos que implican la transformación de energía en trabajo, calor, movimiento, etc. Esta lectura es recomendada para aquellos que tienen el interés de aprender un poco más de uno de los factores que más importantes resultan para el desarrollo y progreso de las sociedades modernas.
