oo it's from chemistry
Explanation:
I am little week in chemistry so sorry
Always is a pretty absolute word and since nothing is impossible I would say no. However, usually for the most part technology does follow science.
If you want to develop a technology, you need to understand the physical principals behind it such as dynamics,material behavior, etc. this all requires knowledge physics and chemistry.

Explanation:
Wind is a renewable source of energy widely used as a source of energy in order to minimize the pollution that results from some other sources of non renewable energy.
Wind energy has the advantage of;
1) being a renewable source of energy hence it can be reused and it is not easily depleted.
2) it does not lead to any form of environmental pollution.
On the other hand, a lot of space is required in order to mount as many windmills as possible in order to generate enough electricity to serve a large area. Thus, the disadvantages of wind energy are;
1) A large expanse of land is required in order to generate a meaningful quantity of energy.
2) The occurrence of wind is inconsistent hence generation of energy is not steady.
