Modern information networks allow data conversion, distribution, and access through flexible hardware and software components that can easily be integrated into a limitless array of applications. This network approach has been developing rapidly and may offer a helpful example to guide energy systems. Energy system integration and networking will eventually transform all forms of energy into a fungible commodity. For that to happen, a paradigm shift must remove old boundaries so we can manage energy interchangeably and seamlessly. With the work and investment that are improving energy technologies, the network approach described here can help nearly everyone contribute to energy security in an age of environmental fears and unstable energy costs.
