Peace be upon you

Hello everyone!

How are you?

May Allah help you to be safer and better

Pleased to be with you here

I’d like to welcome all of you

I’m Mr. Muhammad Yusuf from Egypt

I wish we all spend here a nice time ISA

Now, I’d rather start with brainstorming and let me ask you

What are the main sources of energy on our planet?

مصادر الطاقة في كوكبنا


Text Script

Our project today is to find out about renewable energy resources. That means
resources which are continually replaced and will not run out any time soon.
Ramzi, what have you chosen as an example of a renewable resource?

The sun is a renewable source of energy. A lot of living things depend on its
energy for heat and light. This energy can also be captured and used to power
things. For example, if you have a solar calculator, it contains a solar cell,
which uses sunlight to power the calculator. Solar panels that are used on
houses have thousands of solar cells, and they make electricity from the sun’s
heat. The major advantage of solar energy is that, after the solar panels have
been installed, electricity is not expensive to generate.

What about you, Nadia? What did you find out?

In windy places, wind energy can be used to make electricity, using wind
turbines. These turbines are found in ‘wind farms’. They have blades that are
attached to a generator at the centre. The wind spins the blades and the
generator runs. This makes electricity. However, wind turbines can’t work if
there is no wind, and sometimes the wind speed is so high it damages them.

Ibrahim, what’s your example of a renewable resource?

It’s biomass. Biomass is plant material and animal waste that is used as fuel.
For example, wood is a biomass fuel as long as we continue to plant new trees
to replace those we cut down. Biomass can be used to provide heat and also to
make electricity. The biomass is burnt to heat water and make steam. The steam
is then used to make electricity.
