Jae Y. Yang, president and CEO of Mission Solar, told Xinhua that climate change poses increasing challenges to the whole world. Texas has seen severe heat wave and drought this year. Extreme weather has happened more frequently than before.

Global warming calls for urgent efforts for promoting renewable energy, which offers significant opportunities for the clean energy industry, he said.

The company plans to expand its current capacity and reach out to more distributors in the U.S. residential market at the show, Yang told Xinhua.

"The world needs to make a right choice for promoting renewable energy consumption, and needs joint cooperation to meet the goal for emission reduction," Mauricio Ochoa, director of plant operation at Mission Solar, told Xinhua.

REPT Energy, headquartered in Wenzhou in east China's Zhejiang Province, is one of the Chinese companies participating in the four-day show. A series of the company's battery pack, battery system and cell are on show, attracting lots of visitors.

Jason Hong, overseas sales director of REPT Energy, told Xinhua that during the pandemic, cell production in China had seen great development, while the consumption markets overseas also grew a lot.

Face-to-face interactions with overseas markets were caught by the pandemic for nearly three years, he said.

"We hope to reach out to more customers at the expo, better understand North American market and explore more opportunities," Hong told Xinhua.

A series of workshops were held at the show, addressing topics such as innovative solutions to enable faster, simpler, and fairer interconnection of solar energy, wind energy, and energy storage; the latest emerging technologies in clean energy industry; and preparations for the transition to a carbon-free future.

More than 80 exhibitors have participated in the show running from Monday to Thursday.

"RE+" held its inaugural show as "Solar Power International" in 2004 to bring together people, products, and professional development opportunities that drive the solar marketplace.

The event has since evolved alongside the industry, bringing together an extensive alliance of clean energy professionals to become a leading gathering in the clean energy industry in North America.
