Sustainability Guidelines for Geothermal Development
REPORT DECEMBER Sustainability Guidelines for 2013 Geothermal Development Sustainability Guidelines for Geothermal Development WWF Indonesia 2013 Sustainability Guidelines for Geothermal Development ISBN 978-979-1461-35-1 @2013 Published by WWF-Indonesia Supported by British Embassy Jakarta Coordinator Program Indra Sari Wardhani Writer : Robi Royana Technical Editor : Indra Sari Wardhani Technical Contributor : Hadi Alikodra, WWF-Indonesia Budi Wardhana, WWF-Indonesia Nyoman Iswarayoga, WWF-Indonesia Anwar Purwoto, WWF-Indonesia Indra Sari Wardhani, WWF-Indonesia Retno Setiyaningrum, WWF-Indonesia Arif Budiman, WWF-Indonesia Thomas Barano, WWF-Indonesia Zulra Warta, WWF-Indonesia Layout and Design Arief Darmawan WWF Indonesia Graha Simatupang Tower 2 Unit C LetJen TB Simatupang Kav 38 , South Jakarta, 12540 Indonesia Phone: +62-21-782 9461 Fax : +62-21-782 9462 Foreword Energy has become one of the benchmarks of the development of a country and even become a political economic power including Indonesia. Along with the growth of population and economy, it is undeniable that the energy needs of Indonesia also continues to increase rapidly. Most of the source of this energy needs are from non-renewable/ fossil energy such as petroleum, natural gas and coal, and the utilization of it will produce greenhouse gas emissions (GHG) that contribute to global warming and climate change. To improve national energy security in the long term and contribute to global efforts to put a half to climate change, energy conservation and energy diversication through the development of sustainable renewable energy is a necessity. WWF's vision in the energy sector is to encourage the achievement of 100% Renewable Energy in 2050 globally. -
Abandoned Mines Can Be Used As Geothermal Energy Source
17 February 2011 Abandoned mines can be used as geothermal energy source Scientists have reviewed the potential for worldwide development of geothermal energy systems in old, unused mines. The technology is proven in many sites and could therefore help increase the share of renewable energy sources in the energy mix, offering sustainability and job creation, which may make mining operations more appealing to investors, communities and policymakers. The mineral industry is energy intensive and is therefore focusing on developing energy efficiency and cleaner production technologies. It is also expensive to open, operate and close mines, but few are ever considered as being useful once they have been closed. They are often located on marginal, unproductive land in remote, harsh environments and nearby communities may only live in the area as a direct result of the mine. Being often highly dependent on the mine and on imports of (fossil) fuel, such communities are highly unsustainable. The researchers argue that mines could be used post-closure for energy generation (heating and cooling) using the natural heat contained in the mine water. Geothermal energy systems could be implemented to extract this heat using heat pumps, from both closed and potentially working mines. This would offer local employment and energy resilience to the surrounding communities. Other uses of the energy may include melting snow on icy roads (instead of using salt) or supplying heat for fish farms and greenhouses. Several other technologies can extract energy from abandoned mines, including compressed air storage or the direct use of warm mine water to regulate the temperature of microalgae raceway ponds, allowing a longer growing season for cultivation; key products that can be obtained from the microalgae include nutraceuticals and biofuels. -

A New Era for Wind Power in the United States
Chapter 3 Wind Vision: A New Era for Wind Power in the United States 1 Photo from iStock 7943575 1 This page is intentionally left blank 3 Impacts of the Wind Vision Summary Chapter 3 of the Wind Vision identifies and quantifies an array of impacts associated with continued deployment of wind energy. This 3 | Summary Chapter chapter provides a detailed accounting of the methods applied and results from this work. Costs, benefits, and other impacts are assessed for a future scenario that is consistent with economic modeling outcomes detailed in Chapter 1 of the Wind Vision, as well as exist- ing industry construction and manufacturing capacity, and past research. Impacts reported here are intended to facilitate informed discus- sions of the broad-based value of wind energy as part of the nation’s electricity future. The primary tool used to evaluate impacts is the National Renewable Energy Laboratory’s (NREL’s) Regional Energy Deployment System (ReEDS) model. ReEDS is a capacity expan- sion model that simulates the construction and operation of generation and transmission capacity to meet electricity demand. In addition to the ReEDS model, other methods are applied to analyze and quantify additional impacts. Modeling analysis is focused on the Wind Vision Study Scenario (referred to as the Study Scenario) and the Baseline Scenario. The Study Scenario is defined as wind penetration, as a share of annual end-use electricity demand, of 10% by 2020, 20% by 2030, and 35% by 2050. In contrast, the Baseline Scenario holds the installed capacity of wind constant at levels observed through year-end 2013. -
Hydroelectric Power -- What Is It? It=S a Form of Energy … a Renewable Resource
INTRODUCTION Hydroelectric Power -- what is it? It=s a form of energy … a renewable resource. Hydropower provides about 96 percent of the renewable energy in the United States. Other renewable resources include geothermal, wave power, tidal power, wind power, and solar power. Hydroelectric powerplants do not use up resources to create electricity nor do they pollute the air, land, or water, as other powerplants may. Hydroelectric power has played an important part in the development of this Nation's electric power industry. Both small and large hydroelectric power developments were instrumental in the early expansion of the electric power industry. Hydroelectric power comes from flowing water … winter and spring runoff from mountain streams and clear lakes. Water, when it is falling by the force of gravity, can be used to turn turbines and generators that produce electricity. Hydroelectric power is important to our Nation. Growing populations and modern technologies require vast amounts of electricity for creating, building, and expanding. In the 1920's, hydroelectric plants supplied as much as 40 percent of the electric energy produced. Although the amount of energy produced by this means has steadily increased, the amount produced by other types of powerplants has increased at a faster rate and hydroelectric power presently supplies about 10 percent of the electrical generating capacity of the United States. Hydropower is an essential contributor in the national power grid because of its ability to respond quickly to rapidly varying loads or system disturbances, which base load plants with steam systems powered by combustion or nuclear processes cannot accommodate. Reclamation=s 58 powerplants throughout the Western United States produce an average of 42 billion kWh (kilowatt-hours) per year, enough to meet the residential needs of more than 14 million people. -
Are Biofuels an Effective and Viable Energy Strategy for Industrialized Societies? a Reasoned Overview of Potentials and Limits
Sustainability 2015, 7, 8491-8521; doi:10.3390/su7078491 OPEN ACCESS sustainability ISSN 2071-1050 www.mdpi.com/journal/sustainability Article Are Biofuels an Effective and Viable Energy Strategy for Industrialized Societies? A Reasoned Overview of Potentials and Limits Tiziano Gomiero Independent Consultant and Researcher on Multi-Criteria Farming and Food System Analysis, Agro-Energies, Environmental Issues, Treviso 30121, Italy; E-Mail: [email protected]; Tel.: +39-32-0464-3496 Academic Editor: Andrew Kusiak Received: 7 April 2015 / Accepted: 26 June 2015 / Published: 30 June 2015 Abstract: In this paper, I analyze the constraints that limit biomass from becoming an alternative, sustainable and efficient energy source, at least in relation to the current metabolism of developed countries. In order to be termed sustainable, the use of an energy source should be technically feasible, economically affordable and environmentally and socially viable, considering society as a whole. Above all, it should meet society’s “metabolic needs,” a fundamental issue that is overlooked in the mainstream biofuels narrative. The EROI (Energy Return on Investment) of biofuels reaches a few units, while the EROI of fossil fuels is 20–30 or higher and has a power density (W/m2) thousands of times higher than the best biofuels, such as sugarcane in Brazil. When metabolic approaches are used it becomes clear that biomass cannot represent an energy carrier able to meet the metabolism of industrialized societies. For our industrial society to rely on “sustainable biofuels” for an important fraction of its energy, most of the agricultural and non-agricultural land would need to be used for crops, and at the same time a radical cut to our pattern of energy consumption would need to be implemented, whilst also achieving a significant population reduction. -

On Alternative Energy Hydroelectric Power
Focus On Alternative Energy Hydroelectric Power What is Hydroelectric Power (Hydropower)? Hydroelectric power comes from the natural flow of water. The energy is produced by the fall of water turning the blades of a turbine. The turbine is connected to a generator that converts the energy into electricity. The amount of electricity a system can produce depends on the quantity of water passing through a turbine (the volume of water flow) and the height from which the water ‘falls’ (head). The greater the flow and the head, the more electricity produced. Why Wind? Hydropower is a clean, domestic, and renewable source of energy. It provides inexpensive electricity and produces no pollution. Unlike fossil fuels, hydropower does not destroy water during the production of electricity. Hydropower is the only renewable source of energy that can replace fossil fuels’ electricity production while satisfying growing energy needs. Hydroelectric systems vary in size and application. Micro-hydroelectric plants are the smallest types of hydroelectric systems. They can generate between 1 kW and 1 MW of power and are ideal for powering smaller services such as processing machines, small farms, and communities. Large hydroelectric systems can produce large amounts of electricity. These systems can be used to power large communities and cities. Why Hydropower? Technical Feasibility Hydropower is the most energy efficient power generator. Currently, hydropower is capable of converting 90% of the available energy into electricity. This can be compared to the most efficient fossil fuel plants, which are only 60% efficient. The principal advantages of using hydropower are its large renewable domestic resource base, the absence of polluting emissions during operation, its capability in some cases to respond quickly to utility load demands, and its very low operating costs. -
Power from Geothermal Energy History Pros and Cons Pros
Power from Geothermal Energy History The word geothermal comes from Greek “geo” meaning “Earth” and “therme” meaning “Heat”. Since [Ancient Times] people have used geothermal hot springs for bathing, cooking and even healing purposes. Geothermal energy is derived from superheated water inside the earth. The earth’s core can reach temperatures of over 9,000 degrees Fahrenheit and the heat from the earth’s core is constantly moving toward the earth’s surface. The rock surrounding the core sometimes heats up enough to melt creating magma which then floats closer to the surface and carries the heat from below. Sometimes this molten rock pushes to the surface as lava, but typically it stays beneath the surface and heats ground water that has seeped underground from rainfall. Eventually some of this heated water makes its way back to the surface as hot springs or geysers. Throughout the years, engineers have been perfecting ways of harvesting geothermal water to use it to power homes and businesses. In Larderello, Italy in 1904, Prince Piero Ginori Conti tested the first geothermal power generator and lit 4 light bulbs. Seven years later, in 1911, the world’s first geothermal power plant was built in Larderello. Eventually, in 1958, New Zealand become the second producer of geothermal energy in the world and now these power plants exist worldwide. Pros and Cons Pros: If the geothermal water is drilled correctly, there are no harmful emissions put into the air. There are no fossil fuels being used up and sending harmful byproducts into the air. A geothermal power plant takes up a relatively small area of land and can be integrated as a functional addition to a landscape such as the Svartsengi plant in Iceland which provides heated, mineral-rich water for a nearby man-made lagoon. -
Fossil Fuels and Water Quality 75
Chapter 4 Lucy Allen, Michael J. Cohen, David Abelson, and Bart Miller Fossil fuels are essential to the global economy—for electricity production, transporta- tion, plastics and chemicals manufacturing, heating, and many other purposes. How- ever,Fossil the extraction Fuels and processing and of fossil Water fuels, in addition Quality to their use, have profound impacts on the environment and natural resources, including water. Large oil spills— such as the recent Deepwater Horizon drilling rig spill, which leaked over 4.9 million barrels (780,000 cubic meters) of crude oil into the Gulf of Mexico—have focused atten- tion on the potential for disasters associated with oil drilling to cause contamination of the natural environment (Lubchenco et al. 2010). The growing recognition of the seri- ous risks to surface-water and groundwater quality from natural gas fracking operations also raises new questions. And even normal fossil-fuel extraction and refining processes pollute the environment. The connections between water and energy have been studied in recent years, with growing recognition of how closely the two are linked. Water is used, in varying quanti- ties and ways, in every step of fossil-fuel extraction and processing (Ptacek et al. 2004). For example, the amount of coal produced worldwide in 2009 required an estimated 1.3 to 4.5 billion cubic meters (m3) of water for extraction and processing.1 Oil refining requires approximately 4 to 8 million m3 of water daily in the United States alone (the amount of water that two to three million U.S. households use daily) (US DOE 2006). -
