maybe and maybe not, who knows ! :)
wind energy is only air but wind mills and wind turbins are about 5m to 10m dollars... so yes they are expensive.
yes
because it's natural and you don't have to pay to get wind!
I would use both. One to blow wind for my wind energy

Windmills are a good way to use wind energy

Setting up wind mills can be expensive but using the wind energy for everyday appliances can actually save you up to $2000 a year.
Right now, Singapore does not use wind energy.
No. Wind farms are very unreliable as a constant source of energy. They are also expensive to build and maintain.
Wind energy
Some potential problems with using wind as an energy source include variability in wind speeds, which can impact energy production consistency, as well as the need for large expanses of land for wind farms to be installed. Additionally, wind turbines can be expensive to manufacture and install, which may affect the overall cost-effectiveness of wind energy.
