Research and development (R&D) on marine renewable energy (MRE) in Malaysia is still in its initial stage. It is crucial to know the level of acceptance of MRE among Malaysians in order to push the technology forward. A survey was conducted to investigate public acceptance of MRE in SS2, Petaling Jaya. In addition, a face-to-face interview was conducted to understand the concerns of an investor about investing in renewable energy (RE) projects. The results of analysis showed that 82.8% of the respondents support MRE implementation in Malaysia. However, 56.8% of the respondents are reluctant to pay for green electricity. The reason is directly linked to the NIMBYist (NIMBY=Not in My Backyard) attitudes of Malaysian citizens. They are unwilling to support green energy by involving themselves, participating or paying money. Furthermore, the interviewee, on behalf of investors, expressed some opinions on concerns about investment in RE projects. Several ministries and departments are suggested as being important in MRE development. (C) 2013 Elsevier Ltd. All rights reserved.
