If there were any doubts about the global potential for renewable energy, Michael Lewis, COO at E.ON Renewables, quickly put them to rest. Opening up Thursday's keynote at this years RETECH conference in Washington, D.C., Lewis told the audience renewables will continue to expand, with global capacity expected to increase three-fold by 2020. "When people ask me if renewables are just a niche, I show them the data we've put together," he said.
Lewis expects the industry to grow between seven to fourteen percent leading up to 2020. And he thinks investment dollars will follow, citing the seventeen percent year-over-year growth for renewables in 2011. He explained that in spite of the natural gas surplus in the United States, renewables like solar bring predictability to pricing, which reduces volatility in wholesale and retail utility markets.
