Some renewable resources are as follows:
• Water: Freshwater makes up only 2.5% of Earth’s total water. It plays a critical role in
various applications, such as generating electricity through rivers and harnessing
tidal energy from seas and oceans.
• Solar Energy: Solar energy, sourced from the Sun, is a versatile renewable resource.
It can be transformed into electricity for powering devices like calculators, street
lamps, room heaters, and water heaters.
• Wind Energy: Wind energy is derived from the movement of air and has been
traditionally used for activities like grinding grain and pumping water. Today, it is
also converted into electricity through wind turbines.
• Biomass Energy: Biomass energy comes from organic materials, including plant
and animal waste. It is a renewable resource used for cooking, heating, and
generating electricity.
• Soil: Soil provides essential nutrients for plant growth and serves as a base for
constructing shelters. However, its quality can degrade due to harmful chemicals,
land pollution, deforestation, and urban development.
• Forests: Forests are crucial for maintaining ecological balance. They purify air,
contribute to rainfall formation, and provide valuable resources such as wood,
fruits, and medicinal plants.
Some non-renewable resources are as follows:
• Coal: A cost-effective and widely used fuel, coal is vital for electricity generation,
heating, and industrial processes.
• Petroleum: Petroleum products like petrol, diesel, and mineral oils power vehicles,
industrial furnaces, and electricity generation in power plants.
• LPG (Liquefied Petroleum Gas): Derived from petroleum, LPG is commonly used
for cooking and as a vehicle fuel.
• Natural Gas: Formed from decomposed organic matter, natural gas is often found
above oil in wells. Its compressed form, CNG (Compressed Natural Gas), is widely
used as vehicle fuel.
