Present electricity grids are predominantly thermal (coal, gas) and hydro based. Conventional power planning involves hydro-thermal scheduling and merit order dispatch. In the future, modern renewables (hydro, solar and biomass) are likely to have a significant share in the power sector. This paper presents a method to analyse the impacts of renewables in the electricity grid. A load duration curve based approach has been developed. Renewable energy sources have been treated as negative loads to obtain a modified load duration curve from which capacity savings in terms of base and peak load generation can be computed. The methodology is illustrated for solar, wind and biomass power for Tamil Nadu (a state in India)....

Rising world prices, the growing demand for energy, and the need to mitigate the greenhouse effect are the driving force behind the renewed interest in the use of biofuels. Among the biofuels, biodiesel is one of the best available resources for diesel fuels in diesel engines. Chemically biodiesel is mono alkyl esters of long chain fatty acids derived from renewable feed stock. This article provides in depth and systematic data (reviews from 1944-2010) on technical aspects of biodiesel which will be useful for research and commercial utilization of such promising fuel in a global scenario. This article focused on identification of biodiesel sources, production processes including, pyrolysis, dilution, microemulsion,...
In order to promote the production and use of electricity generated from renewable energy sources, support schemes such as the Renewables Portfolio Standard and various green power programs have been implemented. When evaluating the costs and benefits associated with those schemes, people need accurate information about the characteristics of renewable generation. The objective of the present paper is to identify the kind of information to be provided to lay people in Japan in order to enhance their understanding of biomass generation. We used the two-stage "mental model" method to conduct open-ended interviews and a questionnaire survey to reveal people's beliefs about biomass generation. From the survey results,...

In 1967 and 1968 the USGS, in partnership with NASA and the National Park Service, extracted rock core from 13 locations in Yellowstone National Park. Depths of the holes ranged from 215 ft to 1,088 ft and the total drilled footage was 6,802 ft. The deepest hole was drilled in Norris Basin. Research on these cores provided critical understanding of complex geothermal systems that would inform the potential development of other systems, external to the park, as energy sources. These cores are extremely rare due to the many restrictions on sampling in the park. Years later, the cores were used to investigate the origin of some of Yellowstone supervolcano’s lavas using techniques that did not even exist when the cores...

We assess different policy options for reducing greenhouse gas emissions and promoting the development and diffusion of renewable energy technologies: (1) a carbon emissions price, (2) a generation subsidy for renewable energy, (3) a tax on fossil fuel generated energy, (4) a portfolio (market share) requirement for renewable energy sources, (5) a tradable performance standard for the emissions intensity of all generation, and (6) a subsidy for R&D investment in renewable energy technology. We evaluate the relative performance of the different policies according to different potential goals: emissions reduction, renewable energy production, R&D, and welfare. We also assess how the nature of technological progress—whether...
Rising global demand for energy, high energy prices, climate change, and the threat of terrorism all point to the need for greater energy efficiency and conservation in the United States. While technological innovation is plainly needed, our laws and institutional arrangements must also play an important role. The United States has scores of legal and policy tools from which to choose to improve energy efficiency and curb energy consumption. This Article, which grows out of a Spring 2006 seminar at theWidener University School of Law, evaluates a handful of these tools: transit-oriented development; fuel taxation; real-time pricing for electricity use; public benefit funds; improving the efficiency of existing residential...
Interest in renewable energy has never been greater, but much uncertainty remains as to the role the various technologies will play in the transition to a low-carbon future. This book sets out the facts - how the technologies work, where and to what extent they are currently employed, and where the greatest potential lies. Covering all the major fields - solar electricity, solar thermal, solar architecture, bioenergy, wind, geothermal, hydropower, as well as new energy technologies - it also includes sections on how best to promote the uptake of renewables and answers to common questions and opposition. The authors provide a number of German-sourced yet internationally relevant examples and strategies which have...
Stakeholder analysis allows analysts to identify how parties might be affected by government projects. This process involves identifying the likely impacts of a proposed action and stakeholder groups affected by that action. Additionally, the process involves assessing how these groups might be affected and suggesting measures to mitigate any adverse effects. Evidence suggests that the efficiency and effectiveness of government actions can be increased and adverse social impacts mitigated when officials understand how a proposed action might affect stakeholders. This report discusses how to conduct useful stakeholder analyses for government officials making decisions on energy-efficiency and renewable-energy technologies...
The success of carbon capture, storage and sequestration as a greenhouse gas mitigation strategy will be, in part, dependent on the regulatory framework used to govern its implementation. Creating a science-based regulatory framework that is designed with enough flexibility to encourage greenhouse gas offset activity, effective means of measuring the costs of taking action to reduce greenhouse gas emissions, and ample protection for human and ecosystem health may prove challenging. For the purposes of this paper we will assume that there is an existing incentive to capture, store and sequester carbon and focus on how to regulate the process. Accounting practices and precursory crediting rules for biological sinks...
Projections are important tools for long-term planning and policy settings. Renewable energy sources that use indigenous resources have the potential to provide energy services with zero or almost zero emissions of both air pollutants and greenhouse gases. Currently, renewable energy sources supply 14% of the total world energy demand. Renewable energy is a promising alternative solution because it is clean and environmentally safe. Approximately half of the global energy supply will be from renewables in 2040. Photovoltaic systems and wind energy will be able to play an important role in the energy scenarios of the future. The most significant developments in renewable energy production are observed in photovoltaics...
The paper discusses the nature of hydroelectric energy and how it is integrated into modern power systems. The role of tidal power and pumped storage schemes are mentioned briefly. The principal constraints to the wider development of hydropower are concerned with their effect on the environment, their high initial cost, and uncertainty over the future price of oil. These constraints are discussed, together with brief mention of how the challenge each represents is being countered. Representative recent technical advances, particularly in the civil engineering field, are described. The paper concludes with a brief account of some of the institutional problems encountered in promoting hydroelectric projects, particularly...
The European Union has established challenging targets for the share of renewable energies to be achieved by 2020; for Spain, 20% of the final energy consumption must be from renewable sources at such time. The aim of this paper is the analysis of the consequences for the electricity sector (in terms of excess cost of electricity, investment requirements, land occupation, CO2 emissions and overcapacity of conventional power) of several possibilities to comply with the desired targets. Scenarios are created from different hypotheses for energy demand, biofuel share in final energy in transport, contribution of renewables for heating and cooling, renewable electricity generation (generation mix, deployment rate, learning...
