Energy Matters
University Hall 202
Dr. Shikha Bhattacharyya, Indiana State University

Energy is one of the most important needs of our lives today. We are familiar with renewable (wind, solar, geothermal) and non-renewable (fossil fuels) sources of energy and how we have to transition to more sustainable and less polluting forms of energy to combat greenhouse effects. Most of our focus today is on producing and storing more and more energy to meet the ever increasing demands of growing populations. Energy conservation doesn’t get much attention in the United States where energy is much cheaper than in the rest of the world. Consequently, energy consumption per capita in the US is the highest in the world. Other developed nations with high standards of living manage to meet their demands with much lower energy consumption. According to the second law of thermodynamics, energy can be neither created nor destroyed. However, energy can change forms, and energy can flow from one place to another. This talk is to discuss how energy is converted into non-usable forms and how the process can be reversed to bring the balance back to the environment.
