RESOURCESRENEWABLE NON-RENEWABLE
INTRODUCTION INTRODUCTION
TYPES TYPES
“D”MERITS “D”MERITS
INTRODUCTIONnatural resource which can replenish with the passage of time, either through biological reproduction or other naturally recurring processes. The term renewable resource also describes systems like sustainable agriculture and water resources.
Sustainable development (SD) refers to a mode of human development
TYPES
sun
Solar energy is the most abundant and easily available renewable resource
solar power including solar cookers, solar stills, solar water heating
WIND
Wind power is the conversion of wind energy into a useful form of energy.
originally developed for milling grain for food production
HYDROPOWER
energy derived from the movement of water in rivers and oceans
hydroelectric power involves creating a dam, and using the resulting water force to turn a water turbine and generator
GEOTHERMALGeothermal energy comes from the Earth's crust
MERITS
Pollutant free
Easily available
Found across the globe
Never extinct
“D”MERITS
Very costly
Harmful for wildlife
Can’t be use all the time
Requires vast land
INTRODUCTIONNatural resource which cannot be reproduced, grown, generated, or used on a scale which can sustain its consumption rate.consumed much faster than nature can create them.
Eventually fossil-based resources will become too costly to harvest and humanity will need to shift its reliance to other sources of energy. These resources are yet to be named.
COALFormed from fossilized plants and consisting of carbon with various organic and some inorganic compounds
Oil
A carbon-based liquid formed from fossilized animals.
Pipes are sunk down to the reservoirs to pump the oil out.
TYPES
NUCLEAR
Radioactive minerals such as uranium are mined.
Electricity is generated from the energy.
WOODObtained from felling trees, burned to generate heat and light.
MERITS
Used worldwide
Main sources of energy
Relatively cheap to extract
readily available
“D”MERITS
gives off atmospheric pollutants
Only a limited supply.
Uneven distributed globally
costly to harvest
NUCLEAR FUSION
CONCLUSION
We should use the non-renewable resources very wisely and effectively.We should save them for future generation by giving ore focus on SUSTAINABLE DEVELOPMENT. Human beings have already started using alternate for limited resources. But these should be used all over the world.
