The document discusses different types of energy sources. It defines energy as the ability to do work and explains that most energy comes from burning fossil fuels, though this poses environmental problems. Solar and wind are introduced as more eco-friendly renewable energy sources that can be replenished. Renewable energy sources include hydroelectric, solar, and wind power. Non-renewable sources are coal, natural gas, and nuclear energy, which are finite and cannot be replenished once depleted. The document encourages accessing an online Kahoot quiz to learn more about energy sources.

3. WHAT'S ENERGY
• POWER DERIVED FROM THE UTILIZATION OF PHYSICAL OR CHEMICAL
RESOURCES, ESPECIALLY TO PROVIDE LIGHT AND HEAT OR TO WORK MACHINES
• THE ABILITY TO DO WORK .

4. WHERE CAN WE GET ENERGY FROM
• MOST FREQUENTLY, WE GET ENERGY FROM BURNING FOSSIL FLUES, BUT IT CAN
ALSO COME FROM NUCLEAR AND HYDROELECTRIC POWER. ALL THREE
METHODS POSE ENVIRONMENTAL PROBLEMS. SOLAR AND WIND ENERGY,
HOWEVER, ARE AMONG MORE ECO-FRIENDLY, RENEWABLE ENERGY RESOURCES –
THAT MEANS WE CAN’T USE THEM UP. MAJOR SOURCES OF ENERGY DEPLETION
ARE TRANSPORTATION, HOME HEATING, AIR CONDITIONING, HOT WATER, AND
INEFFICIENT APPLIANCES, MOTORS AND LIGHTING.

5. FORMS OF ENERGY

6. FORMS OF ENERGY
RENEWABLE
• RENEWABLE SOURCES OF ENERGY
CAN BE RESTORED ONCE USED,
• IT CAN BE USED AGAIN AND AGAIN
THROUGHOUT ITS LIFE.
NON-RENEWABLE
• NON-RENEWABLE SOURCES OF
ENERGY CANNOT BE RESTORED ONCE
USED,
• IT CANNOT BE USED AGAIN AND
AGAIN BUT ONE DAY IT WILL BE
EXHAUSTED

8. THREE MAJOR SOURCES OF RENEWABLE
ENERGY SOURCES
HYDROELECTRIC
POWER
THIS USES FLOWING WATER TO
MOVE TURBINES WHICH GENERATE
ELECTRICITY. HYDROPOWER
PROVIDES 20 PERCENT OF THE
WORLD’S ENERGY NEEDS,
SOLAR POWER
CONVERSION OF ENERGY FROM
SUNLIGHT INTO ELECTRICITY,
EITHER DIRECTLY USING
PHOTOVOLTAICS (PV).
WIND POWER
WIND POWER IS THE USE OF AIR
FLOW THROUGH WIND TURBINES
TO MECHANICALLY POWER
GENERATORS FOR ELECTRIC POWER

9. MAJOR SOURCES OF NON-RENEWABLE
ENERGY SOURCES
COAL
COAL IS A HARD, BLACK ROCK-LIKE
SUBSTANCE THAT IS MADE UP OF
CARBON, HYDROGEN, OXYGEN,
NITROGEN AND VARYING AMOUNTS
OF SULPHUR.
NATURAL GAS
NATURAL GAS IS ANOTHER FOSSIL
FUEL THAT IS TRAPPED
UNDERGROUND IN RESERVOIRS. IT
IS MOSTLY MADE UP OF METHANE.
YOU MAY HAVE SMELLED METHANE
BEFORE. THE DECOMPOSING
MATERIAL IN LANDFILLS ALSO
RELEASE METHANE, WHICH SMELLS
LIKE ROTTEN EGGS.
NUCLEAR
NUCLEAR ENERGY IS ENERGY THAT
IS RELEASED WHEN AN ATOM IS
SPLIT. A TREMENDOUS AMOUNT OF
ENERGY IS RELEASED IN THE FORM
OF BOTH HEAT AND LIGHT WHEN
AN ATOM IS SPLIT.
