The Future’s So Bright…

When he started trying to sell the idea of renewable energy at 19, people called him nuts. Today at 35, Darren Kimura heads three companies that do billion-dollar business in solar energy with clients around the world.

Starting out as a teenager with a ‘crazy’ idea, Darren Kimura now has three renewable energy companies

“Be the change you want to see in the world” - Mahatma Gandhi

Darren T. Kimura “walks the talk” - and then some.

A visionary and innovator, at 35 years old Kimura is the founder of three of Hawaii’s most prominent renewable energy companies: Energy Industries, Sopogy and Keahole Solar Power.

To date, his companies have saved Hawaii just short of $1 billion in energy costs, and have cut yearly oil imports by roughly 10,000 barrels of oil a year.

And he’s just getting started.


“Our goal is to save Hawaii several billion dollars at some point,” says Kimura, a born-and-raised Hilo boy. “In Hawaii, we’re maybe 13 percent energy independent, and my mission is to move the needle to well over 50 percent (energy independent). We’ve got a lot of work to do, but I think we’ll get there.”

And he has the knowhow, drive, passion and experience to back it up.

It all began with a 19-year-old and a mission - to convince people that global warming was real, that energy was becoming expensive and something could be done about it. That was 1994 and the inception of his first company, Energy Conservation and Management Hawaii (ECMH), now called Energy Industries.

Energy Industries is an energy project developer that focuses on efficiency and renewable solutions to help large businesses with their energy problems. EI brings energy efficiency and renewable energy solutions to customers as a comprehensive offering.

“What that means is they will go into a large business and look at everything that uses energy and figure out ways to use less energy,” says Kimura. “For example, changing the air conditioning or lighting systems. Through these retrofits the customer can reduce their bill up to 50 percent. So it’s a very effective way for customers to save money.

“When I started Energy Industries, I was driving around in my car trying to convince people of this idea, and the response I got about 80-90 percent of the time was, ‘You’re nuts,’” says Kimura, a Waiakea High School grad. “People have called me crazy. But I believed in our work and kept at it, and over time business got better.”

The company later expanded throughout the state, then to the West Coast, and today has offices in Seattle, Spokane, Portland, Boise, San Francisco and throughout Hawaii. Corporate clients include Boeing, Macy’s and Starwood Hotels.

But this success only came after its fair share of usual entrepreneurial bumps and bruises, which Kimura says are necessary.

A college student at the time, Kimura skillfully juggled earning bachelor’s degrees in business and engineering, while building his company.

“Starting at 19 years old was challenging,” he admits. “I was irrelevant to the business community at 19. They saw a young kid with a crazy idea and poor timing. The lessons learned were valuable, and I soon figured out how to create value in the business and to tell my story better. This ultimately gave me the courage to branch out from Hawaii and expand our business globally.”

Energy Industries’efforts to make saving energy simple have been recognized with awards such as Trade Ally of the Year 2005 (Hawaiian Electric) and Technology Company of the Year 2007 (Pacific Technology Foundation).

“Business is hard, and anyone who tells you starting and growing a business isn’t hard is either lying or they’re about to be severely disappointed,” says Kimura. “Not one good entrepreneur I know says it’s easy, particularly if you’re starting from scratch. When you’re in the start-up phase you will be tested almost daily. In my career I’ve wanted to give up so many times. but when you believe that what you’re doing is more than making a check, that helps a lot.”

It took about eight years before Energy Industries took off, but when it did Kimura was already looking ahead, and in 2002 Sopogy was born.

“It was through Energy Industries that we found the need for a more energy-efficient solar technology that was more reliable than conventional photovoltaics (PV),” says Kimura.

“Sopogy” is derived from the company’s key words - solar power technology. It is a leader in MicroCSP technologies that bring the economics of proven large-scale concentrated solar power systems (CSP) to the distributed generation markets. MicroCSP technologies are used to create steam, solar air conditioning or electrical power. Sopogy is focused on bringing a new renewable energy technology to the market, using its solar energy systems (SopoNova, SopoFlare and SopoLite) to produce electricity.

“Basically we invented a panel (SopoNova), which uses mirrors to concentrate and intensify the energy of the sun,” says Kimura. “The panels also follow the sun all day long, so as the sun moves through the sky, the mirror follows the sun. Our mirrors reflect sunlight into a pipe where we circulate a heat-transfer liquid. The liquid is used to create steam. Once we have steam, we can create electricity. In addition to the panel we invented the computer-based controls and software to operate the system.”

The result is maximized energy production (two to three times more effective than static solar panels seen on home roofs) while minimizing costs.

The system also has energy storage, almost like a battery, except it isn’t stored in electricity, it’s stored in heat, making it a lot more efficient. This means more energy stored for a longer period of time with a very low cost.

“When you combine the solar collector and the storage, we have a solution that’s very helpful to utilities and valuable to customers,” says Kimura. “Our solar farms can offset one utility generator. The eventual goal is that we’ll have so many of these solar farms out there allowing us to eliminate all fossil fuel generators. This will help Hawaii become more energy independent.

“We spend about $7 billion a year for oil. The oil comes in tankers mostly from foreign soil, and once we burn the oil we need more. So we continue to spend that $7 billion every year. The idea behind what we’re trying to do is to keep some if not all of that $7 billion in the state through energy independence.”

“We’ve done all our research and development in Hawaii, and when we invented the technology it was built for Hawaii, but over the years we’ve realized that it has global market potential,” says Kimura. “Today we have projects in the Middle East, Spain, India and throughout the U.S.”

The need to build such projects turned into another business for Kimura in 2007: “Keahole Solar Power is the developer of large utility-grade projects,” he adds. “Sopogy makes the panel, but Keahole Solar Power builds the renewable energy projects.”

Its first groundbreaking project is Holaniku at Keahole Point, the world’s first MicroCSP solar farm, located at the Natural Energy Laboratory in Kona.

The 2 megawatt thermal energy project, which spans 3.8 acres, utilizes 1,000 Sopogy proprietary MicroCSP solar panels (SopoNova). The farm produces 500 kilowatts of energy, enough to power roughly 200 homes. Holaniku feeds power directly into the HELCO grid and reduces the need to import more than 2,000 barrels of oil annually, and will reduce
