NFPA 70E: Electrical Safety — Lockout/Tagout Principles
In its simplest (and perhaps least effective) form, lockout/tagout (LOTO) consists of three steps: Identify the breaker (or fuse) that supplies power to your equipment. Open the breaker. Hang your lock, and tag on that breaker. This would make it seem that NFPA70E should have maybe three principles, not eight.

Solar Integration: Solar Energy and Storage Basics
Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.
Electrochemical Energy Storage: Applications, Processes, and
Abstract. Energy consumption in the world has increased significantly over the past 20 years. In 2008, worldwide energy consumption was reported as 142,270 TWh [1], in contrast to 54,282 TWh in 1973; [2] this represents an increase of 262%. The surge in demand could be attributed to the growth of population and industrialization over
