ENERGY
THE ABILITY OF A PHYSICAL SYSTEM TO DO WORK ON OTHER PHYSICAL SYSTEMS
ENERGY
• ENERGY IS ALWAYS EQUIVALENT TO THE ABILITY TO EXERT PULLS OR PUSHES AGAINST THE BASIC FORCES OF NATURE.
• THE TOTAL ENERGY CONTAINED IN AN OBJECT IS CALLED POTENTIAL ENERGY
BASICS
• ENERGY CANNOT BE CREATED OR DESTROYED.
• TRANSFER PRODUCES CHANGES IN THE SECOND SYSTEM, AS A RESULT OF WORK DONE ON IT.
TYPES OF ENERGY
POTENTITAL ENERGY
POTENTIAL ENERGY IS THE ENERGY OF AN OBJECT OR A SYSTEM DUE TO THE POSITION OF THE BODY OR THE ARRANGEMENT OF THE PARTICLES OF THE SYSTEM
POTENTIAL ENERGY
KINETIC ENERGY
• THE KINETIC ENERGY OF AN OBJECT IS THE ENERGY WHICH IT POSSESSES DUE TO ITS MOTION
• KINETIC ENERGY CAN BE PASSED FROM ONE OBJECT TO ANOTHER
KINETIC ENERGY • SPACECRAFT USE CHEMICAL ENERGY TO LAUNCH
AND GAIN CONSIDERABLE KINETIC ENERGY TO REACH ORBITAL VELOCITY. IN A PERFECTLY CIRCULAR ORBIT, THIS KINETIC ENERGY REMAINS CONSTANT BECAUSE THERE IS ALMOST NO FRICTION IN NEAR-EARTH SPACE

GEOTHERMAL ENERGY
• There is tremendous amount of natural heat in the earth’s crust.
• If you go just a kilometer down the earth’s surface, there is a temperature exceeding 500 degree Celsius.
• This energy is renewable and can be used for generation of electricity.

OPENTIA AS A EXCELLENT ENERGY RESOURCE
NOPAL CACTUS MORE EFFICIENT THAN
JATROPHA FOR THE DRYLANDS
CACTUS -BIOGAS
• “ALLOWS YOU TO GENERATE INEXHAUSTIBLE CLEAN ENERGY.” MORE EFFICIENTTHAN JATROPHA.
• “AN ACRE OF CACTUS PRODUCES 43 200 M3 OF BIOGAS OR THE EQUIVALENT IN ENERGY TERMS TO 25,000 LITERS OF DIESEL.” WITH THE SAME LAND PLANTED WITH JATROPHA, HE SAYS, IT WILL PRODUCE 3,000 LITERS OF BIODIESEL.
CACTUS -BIOGAS • ANOTHER OF THE PECULIARITIES OF THE NOPAL
IS BIOGAS WHICH IS THE SAME MOLECULE OF NATURAL GAS, BUT ITS PRODUCTION DOES NOT REQUIRE MACHINES OR DEVICES OF HIGH COMPLEXITY.
• UNLIKE NATURAL GAS, CONTAINS PRIMARILY METHANE (75%), CARBON DIOXIDE (24%) AND OTHER MINOR GASES (1%),
• SO IT HAS ADVANTAGES FROM THE TECHNICAL POINT OF VIEW SINCE IT HAS THE SAME CAPACITY HEAT BUT IS CLEANER
• HE SAYS, AND AS SUM DATUM ITS CALORIFIC VALUE IS 7,000 KCAL/M3.
