What makes the energy storage industry so interesting?

The energy storage industry is still fairly young compared to others like wind or solar. This means it’s rapidly growing, changing and innovating (part of what makes working in the industry so interesting).

Why is energy storage important?

Energy storage helps integrate renewable energy resources. It also improves energy grid reliability by providing grid stability services, reducing transmission constraints, and meeting peak demand. Wood Mackenzie Power & Renewables projects U.S. energy storage capacity will grow from 2020 two and a half times by 2026.

Why do companies need a talent strategy for renewables?

In renewables, companies are growing faster than the supply of leaders can keep up with, forcing them to be especially imaginative in competing for, retaining and developing talent. We believe that without a new paradigm of leadership and an associated talent strategy, this global energy crisis will never be solved.
