Design Brief
Problem Statement (What is the problem that your teacher has given you to solve?):
We are running out of fossil fuels or non-renewable sources such as
oil and natural gas. The world needs to use more renewable sources
so that the non-renewable sources will last longer.
Design Statement (How are you going to solve this problem? Include the process you are
going to take to solve the given problem) :
we will solve this problem by building a Wind Turbine. Our cutting
edge wind turbine will be top of the line and generate lots of
electricity with it extraordinary blades.
