Lot's of great information for those who want to be prepared.

I found these reviews on Amazon helpful before I made my purchase:

In a survival setting, the ability to access emergency power may make the difference between life and death. Lights On! is the most extensive guide ever produced on battery power to give you the best chance to succeed if the grid fails.
--Joe Alton, MD, and Amy Alton, ARNP, authors of the no. 1 Amazon bestseller The Survival Medicine Handbook and hosts of the Doom and Bloom preparedness podcast

As a long time reader of Backwoods Home Magazine, I know Jeff Yago is an authority on solar and alternative power. For those who are totally dependent on the power grid Lights On will, hopefully, start the alarm bells ringing. Mr. Yago not only details the threats, he also offers solutions to overcome short- or long-term power loss. If you want to know how to live with power after the grid goes down, this is the book for you.
--John Egan, Dir. PrepperGroups.com

America's enemies know the grid is our weakness. It is just a matter of time before the grid is attacked. Lights On is the first book you should read in your quest to be better protected.
--Vincent VonDoom , Disaster Survival Network

Loved Lights On!

Format: Paperback
My husband and I have lived off grid for decades but Jeff Yago's book gave us lots to think about and improve our lifestyle. Loved the book. It's easy for we untechnically minded folk to understand. Great book and easy to read.
