| Summary/Abstract |
This work compares the return on investments (ROI) of oil versus biofuels in Brazil. Although several renewable energy sources might displace oil, the country's forte is sugarcane biofuels. In our analysis we carry out simplified benefit-cost analyses of producing oil fields, pre-salt oil fields (without and with enhanced oil recovery), a business as the usual ethanol scenario, and a high ethanol scenario. Excluding the ROI from existing oil fields, which is the highest, when the discount rate is 4% or more, the ROI of the high ethanol scenario is greater than that of the ROI of pre-salt oil. Considering a US$40/t CO2 tax, the high ethanol scenario's ROI is greater than the pre-salt oil's ROI if a discount rate of 2% or more is adopted. Moreover, the high ethanol scenario throughput up to 2070 compares to 97% of the pre-salt oil reserve without EOR, and demands 78% of its investment. Pre-salt oil production declines beyond 2042 when the country might become a net oil importer. In contrast, ethanol production reaches 2.1 million boe per day, and another 0.9 million boe of fossil demand is displaced through bioelectricity, yielding a total of 3 million boe (62% of the country's oil demand).

| Summary/Abstract |
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.
