This comprised 34.6 percent (small hydro), 25.4 percent (solar PV), 23.5 percent (biomass), 14.4 percent (biogas) and 2.1 percent (geothermal). Meanwhile, the total RE projects achieving commercial operation was 10,254 with total installed capacity of 621.96 MW (61.8 percent solar PV, 15.4 percent biomass, 11.5 percent biogas and 11.3 percent small hydro. A joint study by the Malaysian Government's Economic Planning Unit (EPU) and the United Nations Development Programme (UNDP) estimated that Malaysia had potential energy savings of up RM46.92 billion from 2016 to 2030. The study shows that the main obstacle from widespread use of energy efficient practices is the lack of regulatory framework. Therefore, MESTECC is working on the framework for the Energy Efficiency and Conservation Act (EECA), the act is expected to be tabled in the Dewan Rakyat at the end of 2019. Apart from drafting the Energy Efficiency and Conservation Act, MESTECC has also reviewed and improved the National Energy Efficiency Action Plan (NEEAP) 2016-2025 and has set a new target to achieve at least 8 percent saving through energy efficiency by 2025. MESTECC will focus on energy efficiency in the building sector as it has been identified internationally as one of the most cost-effective sectors to reduce energy consumption. Building electricity consumption comprises more than 50 percent of the electricity consumption in Malaysia.This shows that there is a great potential for cost savings if Malaysia can improve energy efficiency in buildings. Following the Executive Review Committee on Operations of Lynas Advance Material Plants (LAMP) in Gebeng which was presented to the MESTECC as scheduled on 27 November 2018, the Ministry is concerned with the increasing risk arising from the continued accumulation of residue without a viable solution to manage its accumulation in the near-term. For this reason, the Ministry will not allow the unlimited accumulation of residue at LAMP. In this regard, the following pre-conditions will be applied to Lynas Malaysia for future licences/permission renewals:  The Ministry is confident that this decision will help further ensure the well-being of the community and the environment.
