Alternator Winding Temperature Rise in Generator Systems
TM Information Sheet # 55 Alternator Winding Temperature Rise in Your Reliable Guide for Power Solutions Generator Systems 1.0 Introduction: When a wire carries electrical current, its temperature will increase due to the resistance of the wire. The factor that mostly influences/ limits the acceptable level of temperature rise is the insulation system employed in an alternator. So the hotter the wire, the shorter the life expectancy of the insulation and thus the alternator. This information sheets discusses how different applications influence temperature rise in alternator windings and classification standards are covered by the National electrical Manufacturers Association (NEMA).

1 the Renewable Fuel Standard Program: Measuring the Impact on Crude Oil and Gasoline Prices Philip K. Verleger, Jr.1 This Paper
The Renewable Fuel Standard Program: Measuring the Impact on Crude Oil and Gasoline Prices Philip K. Verleger, Jr.1 This paper examines the impact of the Renewable Fuel Standard program (RFS) on crude oil and gasoline prices. The RFS program was enacted fourteen years ago in 2005, but the particular focus of this paper is on the period from 2015 to 2018. The conclusions offered from this research are that the RFS program has provided economic benefits to consumers in the United States and worldwide. Retail gasoline prices are lower thanks to the program. The findings from an econometric model show that the savings to consumers resulting from the RFS averaged $0.22 per gallon from 2015 through 2018. Quantifying the Benefits of Renewable Fuels The first and most obvious benefit from renewables lies in the price of crude oil. The blending of approximately one million barrels per day of ethanol into U.S. motor fuels over the 2015 through 2018 period has lowered the average price of crude by $6 per barrel. This reduction has cut the retail gasoline price by $0.22 per gallon from the level that would have obtained absent the presence of ethanol in the motor gasoline supply. The lowering of gasoline prices confers a second benefit on consumers. Because gasoline demand is price inelastic, consumers have been able to allocate a smaller percentage of their total consumption budget to fuel purchases. This has allowed them to expend more on other goods. Over four years, US consumers have been able to spend almost $90 billion per year more on other goods because of gasoline prices being pulled down by renewable fuel use. -
Biogas As a Transport Fuel—A System Analysis of Value Chain Development in a Swedish Context
sustainability Article Biogas as a Transport Fuel—A System Analysis of Value Chain Development in a Swedish Context Muhammad Arfan *, Zhao Wang, Shveta Soam and Ola Eriksson Department of Building Engineering, Energy Systems and Sustainability Science, University of Gävle, SE-801 76 Gävle, Sweden; [email protected] (Z.W.); [email protected] (S.S.); [email protected] (O.E.) * Correspondence: [email protected]; Tel.: +46-704-400-593 Abstract: Biofuels policy instruments are important in the development and diffusion of biogas as a transport fuel in Sweden. Their effectiveness with links to geodemographic conditions has not been analysed systematically in studying biogas development in a less urbanised regions, with high po- tential and primitive gas infrastructure. One such region identified is Gävleborg in Sweden. By using value chain statistics, interviews with related actors, and studying biofuels policy instruments and implications for biogas development, it is found that the policy measures have not been as effective in the region as in the rest of Sweden due to different geodemographic characteristics of the region, which has resulted in impeded biogas development. In addition to factors found in previous studies, the less-developed biogas value chain in this region can be attributed particularly to undefined rules of the game, which is lack of consensus on trade-off of resources and services, unnecessary competition among several fuel alternatives, as well as the ambiguity of municipalities’ prioritization, and regional cultural differences. To strengthen the regional biogas sector, system actors need a strategy to eliminate blocking effects of identified local factors, and national policy instruments should provide mechanisms to process geographical conditions in regulatory, economic support, Citation: Arfan, M.; Wang, Z.; Soam, and market formation. -
The Impact of the U.S. Renewable Fuel Standard on Food and Feed Prices
BRIEFING © 2021 INTERNATIONAL COUNCIL ON CLEAN TRANSPORTATION JANUARY 2021 The impact of the U.S. Renewable Fuel Standard on food and feed prices Jane O’Malley, Stephanie Searle Stakeholders have engaged in significant debate around the U.S. Renewable Fuel Standard (RFS) and its impact on food and feed prices since its implementation in 2005. Various stakeholders have expressed concerns that the RFS has adverse economic impacts on consumers, livestock farmers, food manufacturers, and restaurants. This briefing paper reviews evidence of the impacts of the RFS on food prices, with a focus on corn and soy, and presents new analysis on the impact of the RFS on U.S. livestock farmers. We summarize the history of debate surrounding the RFS from the perspective of farmers, industry, and policymakers, and analyze its economic impacts relative to a counterfactual, no-RFS scenario. BACKGROUND ON THE RENEWABLE FUEL STANDARD AND NATIONAL DEBATE Farmers in the United States consider the RFS to be a boon for their industry, particularly for the crops that are biofuel feedstocks, most notably corn and soybean. Today, nearly 40% of the U.S. national corn crop, or 6.2 billion bushels, is used for ethanol production while approximately 30% of soy oil produced in the United States is used in biodiesel.1 The RFS is generally believed by stakeholders to increase corn prices. www.theicct.org 1 David W.

Natural gas is replacing other fossil fuels in our energy mix. One way to reduce the greenhouse gas (GHG) impact of fossil natural gas is to replace it with renewable natural gas (RNG). The benefits of utilizing RNG are that it has no climate change impact when combusted and utilized in the same applications as fossil natural gas. RNG can be injected into the gas grid, used as a transportation fuel, or used for heating and electricity generation. Less common applications include utilizing RNG to produce chemicals, such as methanol, dimethyl ether, and ammonia. The GHG impact should be quantified before committing to RNG. This study quantifies the potential production of biogas (i.e., Citation: Taboada, S.; Clark, L.; the precursor to RNG) and RNG from agricultural and waste sources in New York State (NYS). -
