Energy

ENERGY MANAGEMENT PRINCIPLES INTRODUCTION In the modern days energy has the significant role in our life. With development where we got comfortable life and much modern facilities where we got some problem with excessive use of energy resources as declining of energy sources, climate change. So it is an big challenge for present and future generations as the cost of energy increase and its supply decrease, older buildings needs to modified and new buildings designed to use less energy. The optimization...

Thermal Energy

Lab #7: Thermal Energy Heat is thermal energy being transferred from one place to another, because of temperature changes. This can take place by three processes. These three processes are known as conduction, convection, and radiation. When we place two objects with different temperatures in contact with each other, the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while...

Radiant Energy

Examples of Radiant Energy The term radiant energy refers to energy that travels by waves or particles, particularly electromagnetic radiation such as heat or x-rays. Radiant energy is created through electromagnetic waves and was discovered in 1885 by Sir William Crookes. Fields in which this terminology is most often used are telecommunications, heating, radiometry, lighting, and in terms of energy created from the sun. Radiant energy is measured in joules.

Flow of Energy

The Flow of Energy Stacey Ann Langston SCI/209 February 3, 2013 Cynthia Collin-Clausen The Flow of Energy The marine ecosystem relies on solar energy converted through photosynthesis by producers. Consumers, fish for example, metabolize, and release as chemical energy to convert into mechanical energy. The ecosystem distributes energy to living organisms through heat energy. Decomposers break down dead organisms and deplete them of their...
