Andrew Pidden, managing director of the Singapore-based firm, said the world will move toward a low energy and low carbon economy because of several large drivers the rising cost of energy, the desire to clean up the planet and a push from consumers for green products.
"This trend is going to continue for the foreseeable future, because resources are constrained the atmosphere has been used as a dump for free," said Pidden on the sidelines of a UBS hedge fund conference.
CRA, part of Asia-focused brokerage CLSA, manages $100 million of assets spread over several funds, including a long-short fund that invests in clean tech equity and a more focused fund dedicated to clean water.
CRA has beaten indices such as the MSCI index of Asia-Pacific stocks traded outside Japan since its inception in August 2006, Pidden said without giving details, though many clean-tech funds dived last year.
Pidden said the firm was betting on existing technologies and did not like to take technology risks. He said the areas investors were most interested in, because of the potential scale, were transportation and power generation.
"We believe in 10 years there will be a lot of wind off China and South Korea," he said. "People want electricity coal as power generation needs to be addressed," he said.
China expects wind capacity to hit 100 gigawatts by 2020. Vestas is the world's biggest maker of wind turbines, while Chinese industry suppliers include gearbox maker China High Speed Transmission and China Wind Systems.
A move to fully electric cars would completely change the auto supply chain, from different raw materials such as lithium for batteries to more consumer financing for the higher initial purchasing cost and less need for a spare parts industry.
"In 15 years there will be drop in demand for oil as a transportation fuel," he said.
Chile's SQM is the world's top lithium producer and experts say a lithium boom may be coming. Bolivia holds 50 percent of the world's lithium deposits, but extracting it may be a challenge.
"The era of oil will be over by 2050 because we will have electrified the transportation system," Pidden said confidently.
He said Asian countries were in various states of moving toward such cleaner economies, with Japan leading the globe in making its manufacturing more energy-efficient after the 1970s oil shocks, China building more nuclear power capacity than anyone else, and India studying how to avoid polluting its ground water.
The fund has a large exposure to Japan, home to electric car leaders such as Toyota and Nissan as well as battery firms Panasonic and Hitachi. Automakers and battery firms are now seeking tie-ups.
"Asia leads on battery development, solar panel production, and it's soon to lead in installations with China," he said. "Asia will lead the world in the development of these products."
