Thank you for taking the time to share your positive experience of the culture at RES. We do promote a flexible work environment with many positions having opportunities to travel. We’re happy to know the training and support you’ve received has met your expectations. With any culture, there’s room for improvement and we hope you will reach out to your manager or HR representative should you continue to notice behavior that is inconsistent with our values.

Pros

Ridiculous money spent on appearances and they have stupid fancy espresso and coffee machines in break room. Locally there are lots of places to eat, explore and discover. Pay was okay. Very close to Union station, if you want to avoid traffic.

Cons

First things outside of the company. Locations neat and super expensive. Parking in Denver is like $20 a day. And now for Res itself. Executives are probably over valued (as they are everywhere), highly incompetent, directors, included. Part of this is over expansion, lack of responsibility financially, lack of organization, lack of real leadership, and simply coasting along and keeping up appearances for the status quo. Lots of office politics and highly conscious of status within the organization. Res pretends to care about employees, but it all comes down to money, as expected from any company since 2008 really. They are not genuine or authentic in their culture. They pretend to care, pretend to diversify, but still practice discrimination and hide behind laws that make it legal (honestly so many ways to skirt employee protections in this day and age). As of 2025, it’s also confirmed renewable energy will have less funding from the Feds. This company is already struggling in the UK. The way they operate, it will eventually just fade out.

We recognize that this review reflects a deeply negative experience, and while it’s difficult to hear, we take all feedback seriously. We acknowledge that rapid growth can create real challenges in maintaining consistency, communication, and alignment across the organization. RES is actively working to strengthen leadership accountability, improve transparency, and ensure our values are reflected not just in what we say, but in how we operate. We also want to reaffirm our commitment to creating an inclusive, respectful workplace, and encourage anyone who experiences or witnesses discrimination to use our anonymous hotline or connect with your People & Culture Business Partner right away so they can be properly addressed.
