Question

If the Law of Conservation of Energy states that energy is neither be created nor destroyed, but can only be transferred or changed from one form to another, why do scientists worry about running out of energy in the future?

Answer 1

Scientists worry about running out of energy in future as a result of the energy that's getting used by humans is obtaining reworked into another kind of energy that isn't fruitful to future generations.

• Energy cannot be generated or destroyed; it can only be changed from one form of energy to another, according to the rule of conservation of energy.
• This means that unless energy is introduced from the outside, a system always has the same amount of energy. In the context of non-conservative forces, whereby energy is changed from mechanical energy to thermal energy yet the overall energy does not vary, this is especially puzzling.
• Energy must be changed from one form to another in order to be used.

Answer 2

Scientists worry about running out of energy in the future because energy changing from one form to another is not perfectly conservative as every conversion results in a loss of HEAT energy or Thermal energy. This is called Thermodynamic Inefficiency.

• According to the Law of Conservation of Energy, energy is neither created nor destroyed, but can only be transferred or changed from one form to another.

• Once the heat is lost in the environment it cannot be utilised or wielded again. Thus more Raw Supplies will be required and only NUCLEAR energy will be the solution which is almost inexhaustible and non-renewable energy and is a very disastrous form of energy.
