Setting up and managing a sustainable energy business can provide a lucrative opportunity to participate in this growing sector, while also helping one to create positive environmental and human health impacts.

Entrepreneurs, with a vision, a plan and an approach for financing, are the only survivors in this domain. This field requires people who can educate customers on the benefits of renewable energy and convince them to spend money on their product or service. Though the job is challenging, it will sustain their livelihood as well as of individuals all across the country for many generations to come.
