Electricity, Its Sources, Renewable And Non Renewable.Science For Kids.

What is Electricity? What are its sources? Why is it important to conserve electricity?What are some basic facts of electricity? These are some of the questions addressed in this video.

What is electricity?
Electricity is nothing but energy.
We eat food every day and this gives us energy- Similarly, electricity gives machines and gadgets energy.
Electricity can be generated using the following
• Power stations
• Wind
• Sun
• Water
• Battery

The electricity is generated using one of the sources mentioned above. It is then to transformers which push the electricity long distances using high-voltage transmission lines via pylons. The substation further distributes the electricity to the neighbourhood areas like houses, factories etc.

Power Station
Different power stations use different types of fuel, some of which are: coal, oil, gas and even rubbish. These fuels get burnt and then get made into electricity.
Wind: Windmills use the power of wind to spin a turbine to make electricity. Blowing wind spins the blades on a wind turbine – just like when you blow on a toy pinwheel. When the blades turn, the turbine is operating and electricity is generated.
Solar Energy: It means energy (light or heat) that comes from the sun. A Solar panel also called as photovoltaic panels are used to create electricity from the sun.
Water: The force of the falling water from rivers or lakes creates electricity also known as hydro electricity.
The water is held behind a dam, forming an artificial lake, or reservoir. The force of the water being released from the reservoir through the dam spins the blades of a giant turbine. The turbine is connected to the generator that makes electricity as it spins. After passing through the turbine, the water flows back into the river on the other side of the dam.
