There are various types of Renewable Energy (RE) that has been studied by many researchers in order to find a costeffective energy generation in reducing the non-renewable energy source. In this study, the solar energy was suggested in order to apply the Net Energy Metering (NEM) scheme that has been introduced effective on 1st January 2019, by Malaysian government in achieving 20% national RE target in electricity power mix, reducing the dependency on imported fossil fuels. Based on the data and results, the suitable size of solar panel for a house can be determined based on the daily electricity usage. The findings show that the system size and the cost itself also depends on the estimated amount solar generated set by the consumer.

This paper presents renewable energy resources development as a means of abating the shortfall in electricity generation in Nigeria. Levellized Bus-bar Cost Estimation method is used to carry out cost analysis of various power generation technologies by comparing their levellized costs. Carbon Emissions Pricing theory is also utilized to show that the cost per mega watt of renewable energy resources power plants can be comparable to their fossils counterpart when price is assigned to the emissions that result from using fossil fuels. Finally, government’s participation in time bound renewable energy projects, as well as financial and fiscal incentives are identified as actions that will encourage private sector investments in renewable energy development, which has a stimulating effect on the larger economy.

In the last 10 years, Malaysia has aggressively moved towards a higher penetration of 20% of renewable energy (RE) in the Malaysian energy mix by 2025. Several incentives and initiatives have taken place with the aim of achieving the goals in terms of installed capacity and catching up with the leading countries in these sectors. Since 2011, Malaysia started the Feed-in-Tariff (FiT) before introducing Net Energy Metering (NEM) in 2017, and recently, another initiative known as NEM 3.0 has been introduced. This paper reviews all policies undertaken by the Malaysian government from 2011 to 2021 in spearheading the country to be on par with others, especially those in the Southeast Asian (SEA) region. The effectiveness of each policy on the growth of photovoltaic PV energy installation is highlighted, and the latest update on the NEM 3.0 policy is also discussed. A comparison of each approach in terms of installed capacity and system connection setup to the grid is also considered for the benefit and sharing of knowledge from one of the fastest-developing countries in the region.

In June 2001, Hawaii became the 35th state in the nation to adopt a net energy metering (NEM) law to promote the installation of small (10 kW and less) renewable energy (RE) grid-connected systems across the Hawaiian Islands. What effect has the availability of this law had on the diffusion of NEM photovoltaic (PV) systems in Hawaii? Given the typical abundant sunshine here coupled with consistently high electric utility rates, NEM should be taking off, yet consumer adoption has been slow. What have been the principal impediments to homeowners and businesses going solar electric? While the relatively small number of NEM PV systems installed to date does not allow for definitive conclusions on the ability of the NEM law to achieve its purpose, this initial evaluation will identify what challenges and obstacles exist and make recommendations to overcome them.

By transforming patterns of travel and work around the world, the COVID-19 pandemic is accelerating the transition to renewable energy and the decline of fossil fuels. Lockdowns brought car commuting and plane travel to a near halt, and the mass experiment in which white-collar employees have been working from home may permanently reduce energy consumption for business travel. Renewable energy and electric vehicles were already gaining market share before the pandemic. Under pressure from investors, major energy companies have started writing off fossil fuel reserves as stranded assets that are no longer worth the cost of extracting. These shifts may indicate that “peak oil demand” has arrived earlier than expected.

With the cost of renewable energy near parity with fossil fuels, energy storage is paramount. We report a breakthrough on a bioinspired NRFB active-material, with greatly improved solubility, and place it in a predictive theoretical framework.

Distributed solar photovoltaic (DPV) under net-energy metering with volumetric retail electricity pricing has raised concerns among utilities and regulators about adverse financial impacts for shareholders and ratepayers. Using a pro forma financial model, we estimate the financial impacts of different DPV deployment levels on a prototypical Western U.S. investor-owned utility under a varied set of operating conditions that would be expected to affect the value of DPV. Our results show that the financial impacts on shareholders and ratepayers increase as the level of DPV deployment increases, though the magnitude is small even at high DPV penetration levels. Even rather dramatic changes in DPV value result in modest changes to shareholder and ratepayer impacts, but the impacts on the former are greater than the latter (in percentage terms). The range of financial impacts are driven by differences in the amount of incremental capital investment that is deferred, as well as the amount of incremental distribution operating expenses that are incurred. While many of the impacts appear relatively small (on a percentage basis), they demonstrate how the magnitude of impacts depend critically on utility physical, financial, and operating characteristics.

Malaysia has moved forward by promoting the use of renewable energy such as solar PV to the public to reduce dependency on fossil fuel-based energy resources. Due to the concern on high electricity bill, Universiti Malaysia Perlis (UniMAP) is keen to install solar PV system as an initiative for energy saving program to its buildings. The objective of this paper is to technically and economically evaluate the different sizing of solar PV system for university buildings under the Net Energy Metering (NEM) scheme. The study involves gathering of solar energy resource information, daily load profile of the buildings, sizing PV array together with grid-connected inverters and the simulation of the designed system using PVsyst software. Based on the results obtained, the amount of solar energy generated and used by the load per year is between 5.10% and 20.20% from the total annual load demand. Almost all solar energy generated from the system will be self-consumed by the loads. In terms of profit gained, the university could reduce its electricity bill approximately between a quarter to one million ringgit per annum depending on the sizing capacity. Beneficially, the university could contribute to the environmental conservation by avoiding up to 2,000 tons of CO2 emission per year.

Heat accounts for about one-third of the final energy use and it is mostly produced using fossil fuels in South Korea. Thus, heat production is an important source of greenhouse gas emissions. However, using renewable heat that is directly produced from renewable energy, such as bioenergy, geothermal, or solar heat can save energy and reduce greenhouse gas emissions, rather than transforming conventional fuel into heat. Therefore, an energy policy for renewable heat urgently needs to be established. It is such situations that this paper attempts to assess the consumers’ additional willingness to pay (WTP) or the price premium for renewable heat over heat that is produced from fossil fuels for residential heating. To that end, a nationwide contingent valuation survey of 1000 households was conducted during August 2018. Employing the model allowing for zero WTP values, the mean of the additional WTP or premium for one Gcal of heat produced using renewable energy rather than fossil fuels was estimated to be KRW 3636 (USD 3.2), which is statistically meaningful at the 1% level. This value represents the price premium for renewable heat over heat that is based on fossil fuels. Given that the heat price for residential heating was approximately KRW 73,000 (USD 65.1) per Gcal at the time of the survey, the additional WTP or the price premium corresponds to about 5% of that. When considering that the cost of producing renewable heat is still significantly higher than the cost of producing fossil fuels-based heat, more efforts to lower the production costs of renewable heat as well as financial support of the government for producing and supplying renewable heat are needed to ensure residential consumers’ acceptance of renewable heat.
