What is renewable resources ?
Renewable resources
When talking about classification of resources, we will first see the renewable resources. Renewable resources are those resources that can be replenished or renewed naturally over time. Air, water, wind, solar energy etc are all renewable resources. Renewable resources can be easily renewed by nature.
1. Solar energy
Sun is a big source of energy. The energy that we get from the Sun is called solar energy. All the natural phenomenon like the flowing of wind, water cycle, photosynthesis etc are possible only due to solar energy. Now a day, solar energy is being used to cook food with the help of solar cookers, heat water, light streets, pump water for irrigating fields etc.
2. Hydro-Energy
Water is important natural resources. All living organisms need water to live. Humans need water for many purposes such as drinking, cleaning, cooking and for growing crops. Water flowing into the river or water stored in a dam is sources of hydro energy. The Simple method to use hydro energy is to convert it into electrical energy.
3. Wind energy
Winds are constantly being created in nature. The windmill is a source of electrical energy. These windmills are generally established only at places where most of the days in a year experience strong winds. The energy from this wind is used for grinding grain, pumping water and to produce electricity. In India, many windmills have been set up in different places such as Tamil Nadu, Maharashtra, Rajasthan, Kerala, West Bengal and Gujarat.
4. Biogas
Biogas is a type of fuel which is a mixture of gases such as methane, carbon dioxide, hydrogen etc which is obtained by decomposition of animal and plant wastes like animal dung, with the help of micro-organisms in the presence of water. It is used as fuel in gas stove especially in rural areas.
5. Wood
Wood is an ancient and traditional source of energy. It is mainly a mixture of many carbohydrate compounds. Wood is used to cook food. It leads to deforestation and pollutes air also. In India, still in many villages, they use wood chullas to cook food every day. While having ill effects on the environment, it is also harmful to human health
6. Hydrogen
It is a good source of energy because it does not create pollution and produce maximum energy on burning. Hydrogen has the potential to be the answer to all our energy and fuel troubles. Technology is currently being developed to fully utilize hydrogen efficiency.
7. Alcohol
Alcohol has many commercial and medical purposes. It can use for producing energy. It can be obtained while making sugar from sugarcane. Thus it is a very cheap source of energy. A mixture of petrol and alcohol is being used as a fuel in automobiles. This mixture is called ‘Gasohol’.
8. Air
All living things need air to breathe. Therefore, air is an important natural resource.
9. Water
All living things water in order to survive. And the water cycle means we will essentially never run out of the water. But we must be careful not to pollute water and make it unusable. Drinking and clean water are already scarce in the world.
10. Soil
It is an important resource as this is the layer where plants grow. We all need food in order to survive. We get most of our food from crops grown in the soil.
