20-Year Prospect
This one is pretty basic: the need for energy keeps growing as the population grows. The number of rechargeable devices we all have seems to grow, too, what with smart TVs, dishwashers, clothes dryers, etc. We require a great deal of power to live our daily, more-plugged-in-than-ever lives. Therefore, energy brokers are perfectly positioned for the future.
Why? Higher energy demands and rapidly dwindling resources means smarter solutions will be needed for humanity to press on (and press play).
On a more "micro" note, however, excellent, personal service will never go out of style. Your job is to make it absolutely effortless for a business or homeowner to get the energy they need. That's your value.
As an energy broker, you're saving big wigs and the rest of us regular folk a ton of time and money. And on top of that, you'll be rewarded handsomely for doing so, for as long as you want, because energy and customer service never go out of style.
