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.

Types of renewable resource  Solar  Wind  Geothermal  Biomass  Hydro  Ocean

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.

Types of non-renewable resources  Oil (petroleum)  Natural gas  Coal  Uranium

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.

SHORTAGE OF OIL AND FOOD  Shell chief fears oil shortage in seven years  Rising food prices and spreading hunger, the social order is beginning to break down in some countries
