An Investigation Report on RENEWABLE SOURCES OF ENERGY by Presidium School, Gurgaon India

INTRODUCTION Energy can not be created; it can be converted from one form to other by technical, biological and chemical means: Solar and wind energy into heat and power energy, biomass into heat, electricity or biofuels etc. We have all what we need of energy resources and the conversion technologies in order to ensure a complete supply of clean and green energy. Renewable energy is energy that is generated from natural processes that are continuously replenished. There are many sources of energy that are renewable and considered to be environmentally friendly and harness natural processes. This includes sunlight, geothermal heat, wind, tides, water, and various forms of biomass. This energy cannot be exhausted and is constantly renewed. The most important feature of renewable source is that it can be harnessed without release of harmful pollutants. Renewable energy supplies 18 percent of the world’s final energy consumption, counting traditional biomass, large hydropower, and “new” renewable (small hydro, modern biomass, wind, solar, geothermal, and biofuels)

Renewable energy offers our planet a chance to reduce carbon emissions, clean the air, and put our civilization on a more sustainable footing. Renewable sources of energy are an essential part of an overall strategy of sustainable development. They help reduce dependence of energy imports, thereby ensuring a sustainable supply and climate protection

RENEWABLE RESOURCES OF ENERGY

RENEWABLE RESOURCES ● Solar Energy ● Geothermal Energy ● Wind Energy ● Biomass ● Water

SOLAR Energy from the sun.

WIND Energy from the wind.

Energy from burning organic or living matter. BIOMASS Energy from burning organic or living matter.

Although some resources are renewable, such as fresh water which falls in the form of rain, we still have only a limited quantity of them, and the ever growing global population constantly needs more resources to consume. Many parts of the world have severe water shortages, and this situation is likely to get worse. The technically exploitable amounts of energy in the form of electricity, heat and chemical energy from renewable sources exceed the current world energy consumption by about six fold Therefore we need to conserve them even more from before.

OBJECTIVES OF THE STUDY To understand the concept of renewable sources of energy. To explore the various renewable sources of energy. To be able to construct a model showing different renewable sources of energy like wind, water, biomass etc. To be able to use the knowledge in new and concrete situations of daily life.

INSTRUCTIONAL DESIGN The students carried out a detailed investigation before constructing the model. They explored the books, internet and other media resources to develop an understanding of the concept. After gaining information, they started working on designing a model of a city using various renewable sources of energy. In the process, they collected the various raw materials to construct the model. They assembled all the necessary components to prepare a working model.

FEATURES OF THE MODEL The model “Tomorrow land: Where determination meets dreams” shows a city making use of various renewable sources of energy namely: Solar Energy used to make Wind Mill Rain water harvesting for storage of water in houses. Biogas being used a biofuel in gas stoves

ANTICIPATED OUTCOMES The students were able to create a working model to show the practical use of renewable sources of energy like wind energy, solar energy and conservation of sources like water. The students were able to list the changes that need to be brought our conventional methods of environmental conservation and judicial use of renewable sources of energy.
