The larger the windmill, the more power can be generated.
cause there isnt always strong windThe wind doesn't blow all the time.Wind turbines have to be part of a larger plan to generate electricity from different sources.
The object should be necessarily be placed between the focal point of the concave mirror and the pole of the mirror to produce a larger image(not larger object) behind the concave mirror.

It depends on how much electricity you need. But yes of course, a larger wind turbine traps more energy between its blades, so it is "better" in terms of how much electricity produced. However, if you think about it in terms of other things: 1. Sight pollution Larger wind turbines produce more sight pollution than small ones. 2. Animals Large wind turbines kill all birds or bats that fly into them but small ones don't.
Hydroelectricity is used in larger cities to generate electricity. Water flowing over a dam is heated and then the steam generated turns giant turbines that produce electricity for whole cities.
They did in fact use windmills to pump water from wells, but very little watering of crops occurred from this use. The water produced was usually only sufficient for the farm family's needs plus those of the livestock they raised. Irrigation (watering) of crops usually requires much larger volumes of water than the typical windmill of the 19th century was able to produce.
Some of the more wealthy people in colonial Virginia had larger houses. The poor people had houses that weren't larger that one room! It all depends on what you think of as "big". Overall, colonial people did not have a big house.

Wind energy can harm migrating birds. They are also considered an 'eye sore' on the landscape. When you consider how much energy went into the manufacture of the turbines, against how much energy they produce, it appears they have a larger 'carbon footprint' than is first thought.
More affordable wind turbines range from $200 to $600. These turbines are typically smaller, which means less electricity is generated. Larger wind turbines can cost as much as $2,000 for those used in the home and upwards of $20,000 for those used industrially.

Wind Mills are used to pump water from the earth. Although some wind mills were retrofitted to produce electricity. Wind turbines have large blades that are designed to create lift to turn a rotor. In large scale turbines the rotor usually connects to a gearbox. The gearbox will then be connected to a generator. The generator similar but much larger is like the alternator in a car, produces the electricity. Then the electricity goes into a transformer then to the grid. There are a lot of different designs of wind turbines and some might not have all these components but they all have generators.
