This document discusses electricity generation and energy conversion. It explains that electricity is generated by converting other energy sources, like heat, wind, or sunlight into electrical energy using devices like generators. Generators convert mechanical energy, like from moving water or wind, into electrical energy using the Faraday effect. Motors operate on the same principles but convert electrical energy back into mechanical motion. Most large-scale electricity generation uses alternating current due to its advantages over direct current for transmission. Fossil fuels currently provide the majority of electricity but renewable sources are growing.
An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of rotation of a shaft.

Our earth’s interior - like the sun – provides energy from nature. This heat – geothermal energy – yields warmth and power that we can use without polluting the environment.
Geothermal heat originates from Earth’s fiery consolidation of dust and gas over 4 billion years ago. At earth core – 4,000 miles deep – temperatures may reach over 9,000 degrees F
The Road To Change: Electric Vehicles Power the Future for Everyone Rick Borry
What is the future of electric vehicles (EV) in our gasoline-powered economy? With oil prices plummeting, is there still a growing market for EV? These are just two of the questions that will addressed in this interesting and thought-provoking webinar.
Participants will also learn:
•How new battery technologies coupled with innovations in the electric motor will drive growth in EV markets.
•How solar power can play an important role in powering personal transportation.
•What it will take for EV to create true energy diversity in an established transportation industry.
The world has just witnessed the convergence of personal communication and personal computing, with over seven billion smartphones placed into service over the last eight years.
Attendees of this live webinar will hear from thought-leaders Mark Victor Hansen and Michael Gorton their vision of a not-too-distant future where electric vehicles supplant internal combustion engines in many applications as personal transportation converges with electronics and the power grid.
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.

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.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.

• 160,000+ of high voltage transmission lines
• 176,000 gasoline stations
• 1000’s of oil and gas wells drilled annually in the

17. oil and gas are readily available as a world
commodity at low cost -- equivalent to $ 4 to 5 /
million Btu
US coal is even more abundant and cheaper –
approximately $1/million Btu
US electricity prices remain low relative to
other commodities
The average American family spends only 3
to 4% of their income on energy!!
