¿Energía sostenible para el mundo?
Por Sir Christopher Llewellyn Smith, Director de Investigación Energética en la Universidad de Oxford y Ex director general del CERN.
The mammoth energy requirements of India coupled with the strong push being provided by the government to renewable sources of energy makes this sector a lucrative business prospect. This presentation details the overview of the renewable energy sector in India as well as Gujarat and highlights the business opportunities available within the sector.
Governor Murphy, through Executive Order 28, has set New Jersey on the path toward transitioning to 100% clean energy by 2050.
In June, the Board of Public Utilities (BPU) issued a draft of an updated Energy Master Plan (EMP) that encompasses a dramatically broader scope than previous EMPs, and features a series of seven strategies that will guide the state to address the imminent threat of climate change and to reach Governor Murphy’s 100 percent clean energy goal.
This timely webinar features experts who will provide an overview of the EMP draft, and how it has the potential to result in significant economic benefits, including the creation of new jobs, industries and workforce development opportunities for the state’s residents and business community.
The NJ BPU is accepting comments on the EMP draft until September 16th. Please join us so that you can add your voice with others in the sustainable business community to help make the EMP a strong and effective roadmap to creating a clean energy economy.
this presentation is about the problems in gurugram with the perspective of sustainability which arised due to some reasons. this also shows the zoning plan of the city.
This project enumerates ways to mitigate climate change through eight strategies. Each strategy, called as 'wedge', when implemented could reduce carbon emission by 1b ton by 2055. This project prioritizes these strategies based on cost of implementation and public opinion. Ranks are assigned from 1 to 8, with 1 for highly feasible [low cost and less criticism] and 8 for hardly feasible.
As seen from the presentation, adopting to biofuels is found to be least feasible (rank-8), followed by fuel switching for electricity (rank-7). In contrast, improving transport efficiency is found to be highly feasible (rank-1), followed by efficiency in electricity production (rank-2). Justifications (qualitative and quantitative) are provided for the ranking of each strategy.
In the concluding slides, stakeholder perspectives are provided for automobile industry and industrial/developing nations. The climate wedges concept was developed by Princeton University, Ford and BP to find solutions to greenhouse gas problem (see references).

Building Energy Efficiency Into Energy EquationIJERDJOURNAL
ABSTRACT: The increasing demand of energy in the world has causes the pollution and devastation of environment and also depletion of the resources. It imminent that cannot be avoided, however, There is agitation and confrontation from country to country which later realised that only energy efficiency practices is the means of minimizing the impact to the environment, but developing countries like Nigeria centered only on end users.These studies see how energy efficiency will be built into energy generation processes and the benefit to the environment, economic growth and development of a country.
HOW THE GOVERNMENT OF BRAZIL CAN MAKE THE ENERGY SECTOR SUSTAINABLE.pdfFaga1939
This article aims to demonstrate how the government of Brazil can make the energy sector sustainable in order to collaborate in the fight against global warming and to bequeath the existing energy resources in the country to future generations. According to the International Energy Agency, oil, natural gas and coal are the energy sources most responsible for the emission of greenhouse gases in the atmosphere. In the world, the use and production of energy are responsible for 57% of the emission of greenhouse gases in the atmosphere. In Brazil, the energy sector is responsible for 21% of greenhouse gas emissions. The electricity sector in Brazil has 19.7% of energy sources based on fossil fuels (natural gas, petroleum derivatives and coal and derivatives) and 2.2% of energy sources based on nuclear power plants. In turn, Brazil's energy matrix as a whole has 53.3% of energy sources based on fossil fuels (oil and derivatives, natural gas and mineral coal) and 1.3% are energy sources based on nuclear power plants. For Brazil's energy sector to be sustainable, all these energy sources based on fossil fuels and nuclear power plants must be replaced by renewable energy sources (hydro, solar, wind, tidal, wave, biomass and hydrogen).

Zero Waste City Implementation using Waste To Energy Technology in Myanmarijtsrd
Waste management is a complex topic that is handled in different ways around the world based on available local resources, technologies, and intensity of community initiatives. So, Waste to Energy WTE is a renewable energy technology that has seen a major rise in the last decade as Myanmar has been looking for methods for handling its population boom and related rapid increase in waste generation rates. The conventional fuels required for production of electricity is decreasing day by day and it is very important to find out alternative sources which can be used as the fuel for the production of electricity especially for developing countries like Myanmar. In this paper, feasibility study of waste to energy WTE power conversion plant is presented to fulfil the main aim of zero waste city implementation, Mandalay, Myanmar. With the application of WTE plants, the electricity requirement can be fulfilled and also helpful for environmental condition. For case study, Mandalay Industrial Zone is selected since it has low reliability of power supply form national grid and is suitable for construction of a WTE power plant. The simulation for WTE power plant with a peak load of 30 MW is described using HOMER software. Average energy consumption of the industrial zone is estimated approximately 283 MWh day and WTE has consumed almost 118,935 tonne per year of municipal solid waste MSW . The proposed system is designed to provide approximately 100 of energy from the municipal solid waste for the proposed area.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
