It’s important to define energy, because it’s important to know the nature and scope of a market you’ll be putting your hard-earned dollars into. The Merriam-Webster Dictionary definition of energy breaks it down into several parts.
Energy
Has a dynamic quality
Is a vigorous exertion of power
Is a fundamental entity of nature that is transferred between parts of a system in the production of physical change within the system, and is usually regarded as the capacity for doing work
Is usable power (such as heat or electricity) or the resources for producing such power
For investment purposes, a combination of the third and fourth definitions is apt.
