The time it takes to produce 500 megawatts of electricity depends on the power generation capacity of the plant. If the plant has a capacity of 100 megawatts, it would take 5 days to produce 500 megawatts.
To calculate the cost, you need to know your electricity rate. If the rate is $0.12 per kWh, then using a 5-watt device for 24 hours a day for 31 days would consume 3.72 kWh (5 watts * 24 hours * 31 days / 1000) and cost around $0.45 (3.72 kWh * $0.12).
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.
To answer this question two more factors are needed. One is how long is the television on in a 24 hour period and the second is the amount that you pay per kilowatt hour on your electricity bill.
Your welder uses 240 x 30 = 7200 watts = 7.2 kilowatts. Use it constantly for 8 hours then it uses 7.2 x 8 = 57.6 kilowatt hours. The cost for this 8 hrs is 57.6 x .09 = $5.184. Multiply by 5 to get $25.92 per week.
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.
The time it takes to produce electricity can vary depending on the energy source used. For example, electricity from coal or nuclear power plants can take several hours to days to start producing electricity due to the processes involved. In contrast, solar panels can begin producing electricity almost instantly when exposed to sunlight.
In India we have 300 sunny days - but we ignore this renewable energy to produce electricity.

Convert the watts to kilowatts, and the days to hours. Then multiply kilowatts x hours to get kWh.
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

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).
