Energy is the lifeblood of modern society: it is required to fulfil people’s basic needs and everyday activities, and, in the same vein, the world’s economic processes heavily rely on energy. However, global energy consumption and production is putting high pressure on the earth system and is arguably the main culprit behind climate change; fossil-fuel combustion accounts for two-thirds of total greenhouse gas (GHG) emissions and 80 per cent of carbon dioxide (IEA/OECD 2017). Therefore, decarbonization of global energy systems is of paramount importance for a sustainable future, and a global u...

Legislation regarding renewable energy became significant during the last few years. For this purpose, several international regulations have been adopted to regulate the environmental and energy policies of countries. These regulations are formulated in a wide range of binding instruments and soft laws. However, the proliferation of international instruments coupled with the uncertainty of the principles/rules of international law regarding the development of renewable energy sources necessitates the consideration of an international law approach. In this chapter, the author intends to examin...

ABSTRACT

Bei weltweit steigender Tendenz wird nach unterschiedlichen Schatzungen erwartet, das der Energiebedarf in Deutschland wahrend der nachsten Jahre trotz steigender Wirtschaftsleistung etwa konstant bleibt. Nach einer Studie des ESSO-Mineralolkonzerns wird fur das Jahr 2010 ein Primarenergieverbrauch von etwa 489 Mio. t SKE prognostiziert. Fur den Anteil der darin enthaltenen erneuerbaren Energien wird eine Steigerung von heute 2,7 % auf knapp 4 % (18 Mio. t SKE) angenommen. Dieser relativ kleine, fur realisierbar gehaltene Beitrag zum Gesamtverbrauch steht im Gegensatz zu haufig geauserten Erwa...

Emergy map of renewable energy sources in Korea was made by utilizing the spatial data from the latest satellite-based model to evaluate the emergy of individual energy sources and total renewable empower (emergy per time). Until now, emergy evaluations of nations were limited national total due to its aggregated source data from unevenly distributed weather stations. The sattellite-based spatial data not only improves the accuracy of the measurement but also gives new insight to compare the abundancy of renewable energy spatially. The results showed that the renewable energy with the highest ...

Political flexibility brings about trade-offs for policy-makers aiming to support the deployment of renewable energy sources (RES). On the one hand, it allows incorporating new information on ex ante uncertain benefits and costs of RES policy. On the other hand, it may deter RES investments. This paper scrutinizes how these trade-offs play out economically and politically when RES policy-makers choose the degree of flexibility as well as the instruments to implement flexibility. The analysis builds on a theoretical framework distinguishing between flexibility by design and by adjustment. It is...

FOREWORD A few years ago, during my tenure as the United States ambassador to the small African nations of Rwanda and Lesotho, I was responsible for administering the Ambassador's Self-Help Funds Program. This discretionary grants program, supported by the United States Agency for International Development (USAID) funds, allowed the ambassador to selectively support small initiatives generated by local communities to make their schools more...

This paper discusses the mechanism and principles of tidal energy. As a renewable energy, tidal energy generates electrical power using the potential difference of tides, in which the turbine functions crucially. Through systematic grid integration, energy generated can be efficiently collected and transmitted for practical use. Implementing tidal power programs will bring socioeconomic benefits, whereas environmental degradation and ecosystem imbalance can also be negatively affected.

I consider an economy with fossil fuel and renewable energy and energy storage, and search for the conditions that lead to welfare improvements when energy is stored. I then solve for the optimal decision rule and analyze the long-run tendencies of the economy-energy variables. The findings are threefold. First, energy storage is fostered by the convexity of the marginal utility (prudence), the marginal cost function for fossil fuel energy, and the degree of intermittency. Second, considering a low penetration of renewable energy to the power grid, energy storage is not welfare improving if th...

Kenya’s energy framework is one of the most developed in subSaharan Africa. Numerous reforms instituted by the Kenyan Government over the past two decades have considerably increased competition and efficiency in the energy sector. As an example, between 2011 and 2016, the country’s installed power capacity rose by around 50%, from 1,539 megawatts to 2,341 megawatts. During the same period, access to electricity more than doubled, from about 2,038,625 connections (covering 26% of Kenya’s total households) in 2011, to 4,890,373 connections (extending to over 50% of households) by 2016. Rural el...

To achieve a sustained growth of 8 per cent during the period 2005–31, India would need to grow its primary energy supply by three to four times. Similarly, China’s energy demand is expected to increase by two to two-and-a-half times during the same period. By 2030, the two countries combined together would account for around 25 per cent of the total energy consumption in the world and would become two of the largest carbon dioxide (CO 2 ) emitters. The overall demand for energy in the two countries can be significantly lowered by adopting energy efficiency measures to lower energy intensity. ...

Stochastic, that is to say, the uncontrollable varying of oil prices on the world market, is the cause of considerable concern not only to energy engineers but also of common people. The reason is as simple as that: the price rise per oil barrel on the world market affects the increasing cost of living for all of us. Recently, we have witnessed the rocketing oil price which had no sooner risen to 160 US $ per barrel, when in only a several days it fell to 50 US $.

Concentrating solar power (CSP) is one of the promising renewable energy technologies provided the fact that it is equipped with a cost-efficient storage system, thermal energy storage (TES). This solves the issue of intermittency of other renewable energy technologies and gives the advantage of achieving higher capacity factors and lower levelized costs of electricity (LCOE). This is the main reason why solar tower power plants (STPP) with molten salts and integrated TES are considered one of the most promising CSP technologies in the short term [1]. On the other hand, solar photovoltaic (PV)...

While the very large potential of renewable energy has been known to some scholars at least since the end of the 19th century, the potential is still today commonly underrated in public debate. To get the physical proportions right is a necessary first step in a sensible discussion on possible and desirable development paths. The primary purpose of this chapter is to answer the question if the resources of renewable energy flows are large enough to completely replace fossil fuels and nuclear energy, and to indefinitely support a world population of 9-10 billion people at a living standard equi...

To address the effects of climate change, it is imperative for economies to proactively invest in, and deploy, low carbon energy technologies to meet current energy demands. To this effect, several states in the U.S. have implemented policies to incentivize the growth of renewable energy technologies. One of these policies is the renewable portfolio standards (RPS), which mandates that a certain percentage of the total electricity sales of utilities be sourced from renewable energy sources. This paper examines the effectiveness of these policies in driving the growth of specific renewable tech...

The Electricity Act 2003, the State Electricity Regulatory Commissions (SERCs) have set renewable portfolio obligation (RPO) requiring the obligated entities, namely the distribution companies, captive generators as well as the open access consumers, to purchase a certain quantity of electricity consumption through renewable energy sources. Electricity is procured through such sources at regulated feed-in-tariffs specified by the SERCs. Apart from this, there are favourable conditions for off-take of power, transmission losses as well as transmission charges. The fiscal incentives available to...

Nigeria has been mainly dependent on the conventional electrical energy for a long time, with little effort being done to develop alternative renewable sources of energy. The electrical energy is insufficient to fulfill the energy needs in Nigeria, with statistics pointing out that 80% of the country’s population thrives on combustible biomass from the forest woods. USAID has estimated the current generation of electrical energy to be 12, 522MW with a peak generation that was recorded in 2017 being 5,222MW. The estimated energy gap in Nigeria is 170,008 MW, that could be catered for through re...

For more than a decade, renewable energy certificates (RECs) have grown in use, becoming a common way to track ownership of the renewable and environmental attributes of renewable electricity generation. In recent years, however, questions have risen about the role RECs play in the decision to build new renewable energy projects. Information from a variety of market participants suggests that the importance of RECs in building new projects varies depending on a number of factors, including electricity market prices, the cost-competitiveness of the project, the presence or absence of public pol...

Energy security and energy threat are worldwide issues as fossil fuels are exhaustible due to the robust development and economic growth. Many countries across the border support the efforts for alternative energy generation to ensure their energy supply. An energy transition from unsustainable fossil fuel sources to renewable energy (RE) has been reflected by the promulgation of various law and policies in numerous regions and the establishment of the International Renewable Energy Agency (IRENA). Malaysia has also taken several measures to accelerate RE development including the enactment of...

Renewable energy is gaining interest worldwide with researchers due to the limitations in the use of fossil fuel. The annual rise in global population leads to an increase in the demand for power which cannot be resolved using fossil fuels only. Moreover, emissions from fossil fuels causes negative effects to the immediate environment and global climate, so there is a need for long term sustainable solutions to these issues. Renewable energy resources have shown great potential in the mitigation of these concerns as it produces negligible carbon emission, has an unlimited reserve, and shows an...

A cautious view of the soft-technology path is advised after examining the resource potential, use, and scale implications of renewable energy resources in poor countries. While available technologies would contribute in rural areas, developing countries need a variety of options to support basic industries and to increase crop productivity. Satellite monitoring reveals that there is insufficient sunshine or wind to be of any help in some of the most densely populated areas. There is not enough data available about solar, wind, or biomass potential to assess either their future value as a reso...

The relation between local plants and desertification is also studied, emphasizing the role of the olive tree which is the dominant crop in the area. The main causes which are found to favor the occurrence of desertification include population increase, the extent of areas with low or without plant coverage, overg...

This chapter focuses on the application of renewable energy in power systems. Most renewable energy comes either directly or indirectly from the sun. Most commonly used solar technologies for electricity is the solar photovoltaic (PV) cell. The PV array normally uses a maximum power point tracking (MPPT) technique to continuously deliver the highest power to the load when there are variations in irradiation and temperature. In the actual PV power system, the changes in solar irradiance intensity and temperature are not controllable. Energy from the wind has been harnessed for thousands of year...

The world is very concerned with finding a way to accumulate and use renewable energy. The population of the world is growing and countries that were once considered under developed are growing and these countries need energy. The earth has only so much oil and gas reserves and it will not be enough to sustain the world at the present rate of use. The Desertec Industrial Initiative is working to manage energy in the European market. Every nation is looking into a way to extend its reserves, using wind, hydro and geothermal energy sources. The Sun is a primary form of renewable energy under stu...

This paper presents a comprehensive review on the state-of-art-research on ABEs for improving building energy efficiency. First, a clarified concept of ABE is put forward based on two conditions: The ability of lowering cooling/heating loads in buildings, and performing energy transformation as the key judging factors. Second, four major cate...

With the shift toward renewable energy comes the potential for staggering land impacts – many millions of acres may be consumed to meet demand for electricity and fuel over the next 20 years. To conservationists’ dismay, the more renewable energy we use, the more land we need. This article is concerned with two primary questions: What are the implications of renewable energy development for land use and land use law, and how might the land use context inform emerging energy policy? Siting power plants and transmission lines is notoriously difficult, and renewable energy has proved no exception...
