Photovoltaic cells are variable but a standard 1.6 square-metre (18 square feet) cell as used on roofs in the the UK is rated at 220 Watts. For 3 kW you would need 14 of them. When installed and switched on in strong sunlight they would produce 3kW that is available to you to use, but, if you don't happen to use as much, the excess power goes back into the supply network, and the result is that your local power station will produce that much less electrical power. The boiler will be told (automatically) to throttle back and produce less steam, so it will consume fuel more slowly and send CO2 up the exhaust pipe at a lesser rate. So your solar panels produce an immediate reduction in CO2 emissions, because the energy used in everyone's house has to be generated at the instant it is used.
Food would be prepared by hand as it was done in the days before electricity was a common commodity. The cooking stove would have been fired by wood or coal to produce heat for cooking and baking.
1 kilowatt is equivalent to 1000 watts of energy, the average appliance will consume about 52 watts of energy. there for with the power of 200 kilowatts one would have enough power to reach mars in roughly 39 days
Mechanical energy is the energy of work. Back in the olden days, brave inventors used steam to power turbines, or used water to turn wheels in a river. These are examples of putting mechanical energy to work. The gears inside a wind up clock need mechanical energy to function.
Watts is the product of amps times volts. As you can see this combination could have lots of variables depending on the different voltages that are in use and the variable amperage's of multiply loads. To find watts per year you would first have to find the wattage of the device, then extend it to watts per hour if the device is continually on. Then take this figure times 24 hours in a day and then finally times 365 for the days in a year. This will give you the answer that you are looking for.Alternate answer: The question is fundamentally meaningless. A watt is a measure of energy per unit time. An appliance that uses 60 watts, will use 60 watts in a second, 60 watts in a minute, 60 watts in an hour, or 60 watts in a century. Total energy can be expressed in units like "kilowatt-hours" (equal to 1,000 watts for one hour, or 100 watts for 10 hours, etc.). Our 60-watt appliance, left on continuously, will use about 525 kWh per year.
In India we have 300 sunny days - but we ignore this renewable energy to produce electricity.
A simple electrical device is a 60 watt light bulb. The bulb is consuming 60 watts of electricity from the moment you turn it on. If you keep that light bulb on for 10 hours the power used is 60 watts x 10 hours = 600 watts of power. Electricity is sold in Kilowatt Hours. A Kilowatt is 1000 watts of power. Depending on the state you live in, it sells for 7 to 18 cents per Kilowatt Hour. So if you leave that light bulb on 10 hours per day for 30 days you will have used up 600 watts x 30 days = 18,000 watts of electricity = 18 Kilowatt Hours. At an average cost of 10 cents per Kilowatt Hour that bulb costs you $1.80 per month to leave on. The formula is watts x time x cost per Kilowatt Hour = cost of use...Answer provided by Gene Evangelist

Convert the watts to kilowatts, and the days to hours. Then multiply kilowatts x hours to get kWh.
6 days.
electricity is a boon to us. Now-a-days the things we do is almost with the help of electricity

Watts is a residential district in South Los Angeles, California. It was the scene of a large riot which lasted six days in August 1965. See the related link Watts Riots below for more information.

The wind farm produces 2,310 kilowatts of electricity in a week. This is calculated by multiplying the daily production of 330 kilowatts by 7 (number of days in a week).
