This document discusses sources of energy, distinguishing between non-renewable sources like crude oil, natural gas, and coal that come from the ground or seabed and will eventually run out, and renewable sources like solar, wind, and water energy that do not run out and do not cause pollution. It provides details on how crude oil, natural gas, and coal are extracted using drills and burned to produce thermal energy, while solar panels convert sunlight into electrical or thermal energy, wind turbines convert wind into electricity, and hydroelectric power stations convert water movement into electricity.

2. NON RENEWABLE ENERGY
?Non renewable energy sources come from the ground
and the seabed.
?We cannot replace these materials and they will run
out.
3. CRUDE OIL
?Crude oil comes from the ground or from the seabed.
?We extract it using drills.
?We get petrol from crude oil.
?We burn petrol to produce thermal energy.
4. NATURAL GAS
?Natural gas is a mixture of gases.
?Natural gas comes from the ground or from the seabed.
?We extract it using drills.
?We burn natural gas to produce thermal energy.
5. COAL
?Coal comes from the ground.
?We mine it.
?We burn coal to produce thermal energy.
6. RENEWABLE ENERGY
?The Sun, wind and water are renewable sources of
energy.
?They are renewable sources of energy because they do
not run out.
?They do not cause pollution.
7. SOLAR ENERGY
Solar energy comes from the Sun.
Solar panels turn the Sun¡¯s light into
electrical or thermal energy.
8. WIND ENERGY
Wind energy comes from the wind.
Wind farms turn wind energy into electrical energy.
9. WATER ENERGY
Water energy comes from the water
Hidroelectric power stations turn the movement of
water into electrical energy
