Energy in KWh = 60 x 200 = 12,000 KWh
Energy in Joules = (12000 x 10^3) / (60 x 60) = 3333.33 J (Since J=W/s)

To find the total kilowatt-hours consumed, first calculate the total energy used by one bulb: 60 watts * 200 hours = 12,000 watt-hours or 12 kilowatt-hours. Then, multiply this by the number of bulbs (3) to get the total kilowatt-hours: 12 kWh * 3 = 36 kWh. The electrical energy consumed in the home is 36 kilowatt-hours.

No. They are extracting existing heat from the earth, and converting that to electrical power. There are no fossil fuels burned there.
How do Calcium Pyruvate supplements increase energy?
Calcium pyruvate increases your energy by boosting your metabolism. When your metabolism is boosted, fewer of your consumed starches and sugars are stored as fat as opposed to being burned off by your body. When more starch and sugar is burned off by your metabolism, your energy increases.
What are you hearing when you shake a non-burned out light bulb?
When you shake a non-burned out light bulb, you may hear a slight rattling sound. This is usually caused by a small metal filament inside the bulb that will move and make noise when shaken.
Does the amount of magnesium ribbon burned affect how much magnesium oxide is produced?
Yes, the amount of magnesium ribbon burned does affect how much magnesium oxide is produced. More magnesium ribbon burned will result in more magnesium oxide being produced since the reaction between magnesium and oxygen is stoichiometric, meaning it requires a certain ratio of reactants to produce a set amount of product.
How does a candle disappear totally when burned?
When a candle is burned, the wax and wick are consumed by the flame, releasing heat and light energy. As the wax melts, it is converted into gases and carbon dioxide, which are released into the air. Eventually, all the wax and wick are consumed, leaving no physical remnants of the candle behind.
What did Moses see God as?

The water rose in the beaker because as the candle burned, it consumed oxygen in the air inside the beaker. This created a partial vacuum, causing the water to be pushed up into the beaker due to the air pressure outside.
