Our energy resources.0:14
There are two categories of energy resources, renewable and non renewable.0:23
Non renewable energy sources are almost impossible to replace once they have been used up.0:29
Renewable energy resources, on the other hand, never run out.0:35
Non renewable energy comes from fossil fuels such as coal, oil, and natural gas.0:40
They were formed over millions of years from the remains of living things and are found deep underground.0:46
Fossil fuels release energy when they are burnt, but they also release large amounts of carbon dioxide, which pollutes the atmosphere and increases global warming.0:53
Renewable energy resources include wind, water, and solar power.1:03
The Earth has an endless supply of these forms of power, and using them causes little or no pollution.1:09
The power of the wind is converted into electricity using wind turbines.1:16
Flowing water, whether from dams or ocean waves, can be very powerful, while energy from the sun can provide warmth for our homes.1:21
Cutting down on the amount of fossil fuels we use would reduce pollution and conserve the Earth's resources before they disappear completely.1:30
We can all help, for example, by walking instead of driving and turning off the lights when we leave a room.1:39
