To light a 100 W light bulb, you need to generate 100 W of power. If the power plant is 30% efficient, you need 100/0.30 = 333.33 W of input power. Since coal has 30E6 J/kg of energy, you would need 333.33 W/30E6 J/kg = 0.0111 kg of coal to light the 100 W bulb.

How much coal has to be burned to produce the same amount of energy as is generated by a kilogram of uranium fuel pellet?

Approximately 30,000 kilograms of coal would need to be burned to produce the same amount of energy as is generated by a kilogram of uranium fuel pellet. Uranium fuel has a much higher energy density than coal, making it a more efficient and cleaner source of energy.


Why is nuclear burned in a power station?

Nuclear fuel is burned in a power station to generate heat energy through the process of nuclear fission. This heat is then used to create steam, which drives turbines to generate electricity. This process is used because nuclear energy is a reliable and efficient source of power that can produce large amounts of electricity without greenhouse gas emissions.


What action does not make a home more energy efficient?

Leaving lights on when not in use does not make a home more energy efficient as it unnecessarily consumes electricity.


What energy is transfered to thermal energy when fossil fuels are burned?

The chemical energy stored in fossil fuels is converted to thermal energy when they are burned. This process releases heat energy, which can be harnessed for various applications such as electricity generation or heating.


Does wood produce energy?

Wood can be burned to produce energy in the form of heat. When wood is burned, it releases heat energy due to the combustion process. This heat energy can be used for cooking, heating, or generating electricity in biomass power plants.
