atmosphere–ocean system and motivates the deeper examination to follow. The character of coupled atmosphere–ocean interactions is briefly introduced. Simple energy balance models are derived and used to illustrate the fundamental mechanisms behind variations of temperature with altitude‚ latitude‚ and season. The global annual mean energy balance is then presented and briefly discussed. Finally‚ the origins‚ thermodynamic structure‚ and composition of the atmosphere and ocean are summarized.

Forms of Energy Energy exists in many forms‚ and when these change‚ energy is conserved. Different forms of energy include the following: Mechanical Thermal Chemical Electrical Electromagnetic Nuclear energy All of these types of energy have the ability to do work‚ which is also the definition of energy. Additionally‚ they have other properties‚ which are specific to their own specific form. Nuclear Energy Nuclear energy is energy in the

Presented on Renewable Energy Sources – Policies of India Author- Rucha Korhale BE-Instrumentation Lecturer‚ VPM’s Polytechnic‚ Thane 1 Renewable Energy Sources – Policies of India Abstract:In today’s date‚ India is a large consumer of fossil fuel such as coal‚ crude oil etc. The rapid increase in use of Non renewable energies such as fossil fuel‚ oil‚ natural gas has created problems of demand & supply. Because of which‚ the future of Non renewable energies is becoming uncertain

Energy is an important part of our life‚ and no human being in the 21st century can live without it‚ energy now a day means electricity and electricity is running our world‚ with no energy there will be no electricity and then no hospitals‚ no technology and we will go back to stone ages. Energy sources on planet earth can be classified into two types‚ “renewable” and “nonrenewable” energy sources‚ they both differ in many aspects‚ both of them have advantages and disadvantages‚ and both of them

Calculating Efficiency. Efficiency (%) = Useful Energy Out x 100 Total Energy In Questions 1) A light bulb takes in 30J of energy per second. It transfers 3J as useful light energy and 27J as heat energy. Calculate the efficiency. 2) A kettle takes in 2000J of energy per second. It transfers 1500J as useful heat energy and 500J is wasted as sound energy. Calculate the efficiency of the kettle. Remember: In the exam they may not

Potential Energy Potential Energy is a type of energy that does not involve motion. It is the energy that is stored up. The more work done to change an object’s position or shape‚ the more potential energy it has. For example‚ a person on a ladder has more potential energy than a person on the ground because they have done more work to get up there. Kinetic Energy Kinetic Energy is the energy of motion. The more work an object has done‚ the more kinetic energy it has. the amount of kinetic

Why should we save energy in schools? Saving energy leads to reduce carbon emissions‚lower costs and conserves the supplies we have.They are also working in support with high schools to support energy efficiency."We believe energy efficiency is the cheapest and cleanest form of "new" energy the world has." - energy efficiency unit of Chevron.Even though energy suppliers want your business‚ they are looking for more of an investment instead of wasting energy when it isn’t necessary. They believe

Flemister Renewable Energy is best America’s dependency on foreign oil is costing us more than just money; it costs us our clean air and potentially thousands of jobs in America. Our nation needs to create its own renewable energy. The dependency on other countries is crippling our economy. Drilling for oil in the United States is not the answer. We need to take better care of our planet and that each of us must
