It's quite simple. The wind turns a turbine which generates electricity that can either be stored in batteries to put directly into the grid. If you want more information on how wind power works check out the related link.
A typical grade school using 40KWH of power could be run on less then 25 large wind system and 200 panels rated at 100 watts, assuming you have backup power (fossil fuel) available for low wind and sun conditions and the school did not use air conditioning or heat. The cost of this system would be less then the cost of 100 years of fossil fuels and could provide power for months without maintenence and not need replacement for a decade or so. Power costs would be well over ten times the current rate.
Whether the electricity is generated by conventional power stations, or hydroelectric power generation, the electricity used in homes and businesses will still be the same, and used the same.
It is used mainly for fuel (airplanes, trains, automobiles), as a source of heat for homes and businesses, and in the manufacture of plastics and pharmaceutical supplies, and tar for asphalt.
DC series motors run on DC power. Homes have AC power, not DC power. You could use DC motors in homes if you have a power supply or use a battery, but it is usually more cost effective to use an AC motor.
Yes, they exist. Capacitors are often used to change a low power factor (such as 0.5) to a higher power factor near unity (1). In some instances, this will lower fees and costs to utilities. In homes, this is not really necessary as most devices used in homes are near unity power factor, or tend to be minor/sporadic loads (such as a washing machine).
Photovoltaics means to generate electricity from sunlight. Tiny photovoltaic cells are used in devices such as calculators, to save battery power. Larger systems are used to provide electricity to devices or homes that are far from the interconnected electric network.
Water power is used to produce electricity - all homes schools and businesses use electricity so hydro power is just part of this. If you mean direct water power using your own water wheel to drive some mechanism, this is rather old fashioned. Millers used to do this, but surely no-one still does this? I don't see any relevance to homes and schools, what would they do with a mechanical water wheel?
Whether the electricity is generated by conventional power stations, or hydroelectric power generation, the electricity used in homes and businesses will still be the same, and used the same.
To power homes and businesses
it can be used to power lights, apliences and can be used to power anything in the home work work place.
wind is used to power homes, businesses, etc and is widely used around the world.
Yes, hydro electricity is the same as all electricity. It is called hydro because it is made from the power of water falling. But the electricity is used in homes and businesses for heating, lighting and running machinery.
Yes, it is actually advised that we use solar energy to save power.
So that the materials (chemicals) used to power our lives (cars, trucks, Homes, Businesses) will be made.
Electricity and steam. In some locations the steam is used to heat homes and businesses.
Monochrome laser printers are used everywhere. They are used in people's homes, in businesses, and in schools. The monochrome printer only prints in one color, usually black.
Wind power is being harnessed to generate electricity used in homes, businesses, offices, factories and farms.
Hydro generators are used to power cities, towns and many homes and businesses. They generate electricity that is used both residentially and commercially.
