wind energy is only air but wind mills and wind turbins are about 5m to 10m dollars... so yes they are expensive.
Solar and wind energy are the only 'cheap' energy there.
no but yes. it is the most cheap form of electricity but is way more money then buying an old power plant.
Wnd energy is free
There is no energy when there is no wind. Also, it is expensive to initially set up.
yes
Expensiveeeeeeeee (: x
It is an inexhaustible though expensive means of collecting energy by wind power spinning turbines.
Are expensive to make Need lot of space to plant windmills. Very reliant on the wind - no wind no energy.
because it's natural and you don't have to pay to get wind!
maybe and maybe not, who knows ! :)
no not at all very expensive
Setting up wind mills can be expensive but using the wind energy for everyday appliances can actually save you up to $2000 a year.
