Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. The first kind of energy to be recognized was kinetic energy, or energy of motion.

Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. For example, when a pendulum swings upward, kinetic energy is converted to potential energy.

Law of Conservation of Energy Examples: In a torch, the chemical energy of the batteries is converted into electrical energy, which is converted into light and heat energy. In hydroelectric power plants, waterfalls on the turbines from a height. This, in turn, rotates the turbines and generates electricity.

Abstract- Energy conservation refers to reducing energy consumption through using less of an energy service. Even though energy conservation reduces energy services, it can result in increased environmental quality, national security, personal financial security and higher savings.

2. Educate staff and students about the program.
3. Post signs on printers and copiers.
4. Reuse single-sided paper.
5. Change the default settings on all copiers and printers to double-sided.

How to Conserve Water in the Community

1. Use Water Conservation Devices Encourage the use of water conservation devices by large water-using facilities (such as schools, health clubs, motels, and others.)
2. Survey Water Users – Survey water users within large water-using facilities and develop plans to reduce water use.

Water conservation essay is the paper dedicated to the urgent problem of the contemporary world about the necessity and possible ways of water protection. In this light, the strategies and activities used to protect water environment and save freshwater acquire the core emphasis in the water conservation essay.

Most of us will get along just fine without throwaway plastic in our daily lives. As with medical applications, many substitute materials do not provide the protection or stability that single-use plastics do. Single-use plastics are often used to package food and water.

One significant obstacle is that single-use plastic is almost impossible to avoid. “The consumer often times has little choice to refuse plastic, ” said Trent Hodges, Plastic Pollution Manager for the Surfrider Foundation. “And because it’s so ubiquitous and such a common item, it becomes a force of habit.

IMAGINING A WORLD ENTIRELY WITHOUT PLASTIC IS IMPOSSIBLE It would not be possible to imagine our modern world without mobile phones, computers or the internet. Unfortunately, all these electronic devices require plastics. Without plastics, our global communication and transportation network would cease to exist.

Plastic is durable and provides protection from contaminants and the elements. It reduces food waste by preserving food and increasing its shelf life. It protects food against pests, microbes and humidity. Without this protection, food is more likely to get damaged and become unusable.
