“…This suggests that the government must set a discount rate lower than the current 10-15% to attract investors to renewable energies and add benefit to power producers to shift energy sources from coal to renewables. This result conforms with previous studies affirming that RES with higher proportion of capital investments are more expensive with high discount rate, while electricity generated from coal (and other fossil fuels) with significant proportion of operational and variable costs are far less susceptible to changes in discount rates due to lower capital costs (Copiello et al 2017;Jeon et al 2015;Pereira et al 2013). Hence, lower social discount rates entail greater contributions of renewable technologies while higher social discount rates favor the use of fossil fuels (Gusano et al 2016).…”

This paper aims to analyze the comparative attractiveness of either investing in various renewable energy sources or continue using coal for electricity generation in the Philippines. Using real options approach, this research evaluates the investment value and trigger prices of coal for switching technologies with some scenarios in coal price uncertainty and social discount rate. The results find that investing in renewable energy is a better option than continue using coal for electricity generation. Among renewable energy sources, geothermal is the most attractive to invest to, followed by wind, hydroelectric, and solar photovoltaic.

“…Brazil had 397 power plants in operation in 2011, with an installed capacity of 3.5 GW. Currently, the potential capacity is equal to 25.9 GW [33]. The United States Department of Energy tabulated more than a half million sites, with an installed potential of 100 GW [34], representing 10% of the current generation in the United States.…”

Analyses of possible synergies between energy recovery and water management are essential for achieving sustainable improvements in the performance of irrigation water networks. Improving the energy efficiency of water systems by hydraulic energy recovery is becoming an inevitable trend for energy conservation, emissions reduction, and the increase of profit margins as well as for environmental requirements. This paper presents the state of the art of hydraulic energy generation in drinking and irrigation water networks through an extensive review and by analyzing the types of machinery installed, economic and environmental implications of large and small hydropower systems, and how hydropower can be applied in water distribution networks (drinking and irrigation) where energy recovery is not the main objective. Several proposed solutions of energy recovery by using hydraulic machines increase the added value of irrigation water networks, which is an open field that needs to be explored in the near future.Keywords: irrigation water networks; water-energy nexus; renewable energy; sustainability and efficiency; hydropower solutions; water management Hydropower GenerationSociety's energy consumption worldwide has increased by up to 600% over the last century. This increase has been a direct result of population growth since the industrial revolution, in which energy has been provided mainly by fossil fuels. Nevertheless, today and in the near future, renewable energies are expected to be more widely implemented to help maintain sustainable growth and quality of life and, by 2040, to reduce energy consumption down to the 2010 levels [1].Sustainability must be achieved by using strategies that do not increase the overall carbon footprint, considering all levels of production (macro-and microscale) of the different supplies. These strategies' development has to be univocally linked to new technologies [2]. Special attention must be paid to those new strategies that are related to energy recovery. These new techniques have raised interesting environmental and economic advantages. Therefore, a deep knowledge of the water-energy nexus is crucial for quantifying the potential for energy recovery in any water system [3], and defining performance indicators to evaluate the potential level of energy savings is a key issue for sustainability, environmental, or even management solutions [4].Energy recovery, with the aim of harnessing the power dissipated by valves (in pressurized flow) or hydraulic jumps (in open channels), is becoming of paramount importance in water distribution

Abstract-This paper reviews current renewable energy policies in Malaysia to develop an understanding of the country's progress in achieving energy sustainability given that fossil fuel resources are facing its eventual and gradual depletion; hence the need to develop a project management framework with reference to Malaysia's renewable energy efforts. Extensive literature review was conducted and a comparative analysis were performed to further the understanding of vital modifications and inclinations historically involving the evaluation and assessment of Malaysia's renewable energy policies, its framework as well as its implementation guidelines. These reviews would contribute in developing a policy-writing management framework based upon the SWOT analysis of Malaysia's renewable energy policies. This was then developed to further improve the structural stance of current policies to ensure effective implementation of large-scale renewable energy projects in Malaysia.
