What is energy?
1) Energy: -power that allows things to happen
-ability to do work.
Renewable
Non-Renewable
2)Renewable can be NATURALLY REPLACED over time,
2) non-renewable and cannot be easily replaced
3) they cannot be replaced once extracted from the ground
5) They exist in limited quantities and
cannot be replenished
4) EXEMPLE
COAL
10)is one of the most important SOLID FUELS,
11)is burnt, which heats water, converting it into
steam
12)
causes pollution and greenhouse gases, which can be bad for
the environment.
13)we're using it up
much faster than it can be made.
NATURAL GAS
20) is a fossil fuel
21)it's cleaner than coal and oil when it burns
23)it's still non-renewable because it takes a long
time to form deep underground, and we're using it
faster than it can be replaced.
NUCLEAR FUELS
PETROLEUM
14) is a THICK, DARK LIQUID that we get from deep
underground.
15) use it to make gasoline for our
cars, trucks, and airplanes.
16) is often called BLACK GOLD, it is very valuable,
just like gold
17) Once oil is reached, it flows up the
well or is pumped out.
The crude oil is then refined and once petroleum is refined
18-19) Gasoline (US)– for cars BENZINA
Diesel – for trucks, buses, and some cars
Kerosene
6) creating the greenhouse effect.It causes the rising in
the earth’s temperature
7)They originate from plants and animals that
existed in the past (millions of years ago)
8) creating the greenhouse effect.It causes the rising in
the earth’s temperature
9)they release large amounts of carbon
dioxide (CO₂)
