NATURAL RESOURCES
Materials or substances occurring in nature which can be exploited for economic gain and can be used by people.

TYPES OF RESOURCES
There are two types of resources Renewable Resource Non-renewable Resource

Renewable Resource
The renewable resources are unlimited in nature, and they are not likely to be exhausted by human activities.

WIND ENERGY
Energy can be extracted from the wind by transferring the momentum of passing air to rotor blades.

SOLAR ENERGY The sun has produced energy for billions of years.
Solar energy is the sun’s rays (solar radiation) that reach the earth.
Solar energy is free, and its supplies are unlimited. Using solar energy produces no air or water pollution but does have some indirect impacts on the environment.
For example, manufacturing the photovoltaic cells used to convert sunlight into electricity, consumes silicon and produces some waste products.
Large solar thermal farms can also harm desert ecosystems if not properly managed.

BIOMASS
Biomass is organic material made from plants and animals.
Biomass can be converted to other usable forms of energy like methane gas or transportation fuels like ethanol and biodiesel.

Non-renewable Resource
The non-renewable natural resources are limited in nature and are liable to be degraded in quantity and quality by human activities.

FOSSIL FUEL
Oil was formed from the remains of animals and plants that lived millions of years ago in a marine (water) environment before the dinosaurs.
