Energy efficiency is more of a journey than a battle. It starts with small steps, taken at the local and state levels. It is a matter of identifying and then practicing good habits in our daily lives, at home and at work.

Every idea and process described in this book, if performed reasonably well, will put money in your pocket. You will not only save money; you will probably make money—and you will take important steps toward saving the planet.

Power Economics is a book for thoughtful people who want to cut their energy costs and diminish the harmful effects of greenhouse gas emissions.

Climate change and global warming are not speculative fantasies. They are real. They threaten communities, towns, cities, regions, nations, and continents. Even if you don't care about polar bears and penguins, the effects of melting icecaps and shifting ocean currents will transform your life and the lives of the people around you.

Power Economics offers practical steps and achievable strategies for reducing the destructive impact of climate change and global warming.

Yes, we need energy to live and to sustain our economies. But we don’t need to burn fossil fuels and release CO2 gas at levels that will result in a global catastrophe. There are reasonable alternatives to our current practices. None of the ideas that described in this book are entirely new or totally unfamiliar. They aren't extreme or bizarre. They won't require harsh or draconian measures to work. All of them follow basic rules of common sense and can be achieved at reasonable cost.

"I have done my best to convey the complexity and urgency of the matter. I hope that you find this book informative and useful. Working together, we can shed many of our wasteful energy habits and begin the task of building a world that is safe, sustainable and healthy," writes author and energy expert Elena Cahill.
