The Company

GreenDream Enterprises is currently focused on education, research and direct action. The company has provided consulting services to companies and individuals with a focus on integrating systems, technology and education to create positive results. Renewable energy, green building, alternative transportation and lifestyle choices – all of these topics are a part of the sustainability puzzle.


Steve Rypka is president of GreenDream Enterprises (which includes GreenDream.biz) and is dedicated to “Learning to live lighter on the planet.” He is passionate about all things green, including solar electric and hot water systems, high performance green buildings, hybrid & electric vehicles, green web design & hosting, and other ways that make a positive impact on the environment and community.

Originally from the San Francisco Bay Area, he has lived in the Las Vegas valley since 1978. As a surfer, scuba diver, skier, hiker, sailor and photographer, Steve has always been deeply aware of the fundamental connections we share with our environment. He has studied environmental issues for many years, including the climate crisis. He has focused on green building and renewable energy as key solutions to this critical issue.


Recognizing the need for more awareness about these topics, Steve was a co-founder of the U.S. Green Building Council – Nevada Chapter (USGBC-NV) and Solar NV, the Southern Nevada Chapter of the American Solar Energy Society. He has served on the board of directors for both organizations and is past president of Solar NV, where he organized the first two Southern Nevada Solar Home Tours that became an annual event for over a decade. Now that solar had gained such a strong foothold, the tour is not as crucial as it once was.

For nine years, Steve wrote a Green Living column that appeared every other week in the Las Vegas Review Journal. All but the earliest columns are included in this site’s blog. He has been recognized  by the U.S. Green Building Council and other organizations for his leadership in the community. He is a LEED accredited professional, has taught classes on green living and is an experienced public speaker.


Over the last 20 years, Steve and his wife Marsala have directly reduced their personal carbon dioxide “footprint” by more than 95%. They live and work in a net-zero electric, solar-powered home that produces enough extra energy to power two electric vehicles. They continue to strive to live lighter on the planet, both personally and professionally. Steve believes in the power of Gandhi’s words to, “Be the change you wish to see in the world.”

GreenDream Enterprises has been a member of the U.S. Green Building Council – Nevada Chapter and the American Solar Energy Society. We were also an early adopter of the 2030 Challenge. The window of opportunity is closing for meaningful solutions to climate change that lead to a sustainable future and a healthy economy. Please take action before it is too late.
