Ellie's Report about Wind Turbines
Do you know how wind is used to create energy? Well I will tell you…
In Ancient Egypt, people used wind to power their sailboats along the Nile river. The first windmills were used in Persia in today's middle east region about 1,500 years ago. Windmills in the olden days looked sort of like a egg beaters, and were mainly used by Persian people for grinding grains and and drawing water from wells. Today modern wind turbines are strong, sleek and well sorted for converting the force of wind energy.
Facts on plastic
1. The Plastic gets smashed in to bits
2. The plastic turns into little dust
3. Plastic is used for other things like toys and milk bottles
4. The People make it into a cubes
5. The People can fill a whole rugby field of plastic

Paloma's Solar Energy Explanation
How does solar energy work?
Intro
Did you know fossil fuels are bad for the environment?
Solar power is a renewable energy.
Why do we use fossil fuels not solar energy?
We use fossil fuels because they are cheaper than solar panels.
There are more fossil fuels than solar panels.
How can we collect solar energy?
We can collect solar energy with thermal collectors, solar sails photons and semiconductors.
What are photovoltaic cells?
They are dark panels on a calculator or satellites. They convert sunlight directly into energy.
What are the drawbacks?
They can’t get power that quickly. You need to cover your whole roof with solar panels to get as much power as other houses without them. Solar panels are really expensive and it isn’t always sunny.
Conclusion,
I think we should use solar energy not fossil fuels, because fossil fuels are cheap and bad for the environment.
Cassie's Wind Energy Report
Intro/history
Americans use the second most amount of wind energy. The first windmills were used in Persia. They looked a bit like egg beaters, they were used to grind grain and draw water from wells. In ancient Egypt they used wind power for sailing boats down the Nile river.
How it works
Inside the turbine a generator converts the movement into electricity. The blades convert the wind's energy into a rotational energy called toque. When strong winds blow against a turbine the force causes the rotor blade to turn pretty quickly
Wind farms
An area of land with a group of energy-producing windmills for wind turbines.
Renewable Energy
Is a source of energy that won't run out unlike fossil fuels which will eventually run out
Countries using Wind power
New Zealand,America,India,Germany,France, Spain,The United Kingdom,China,Denmark and Italy.
The Drawbacks
People think there are ugly and they don't like to look at them and so people are concerned that flying animals are dieing from them.
Conclusion
So that's all you need to know about wind energy.
