To summarize, potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
While kinetic energy is the energy in a body due to its motion

Environmental Impacts of Non-Renewable Energy Sources
Perhaps the most well-known impact of using non-renewable energy sources is the emission of greenhouse gases, in particular carbon dioxide and methane, which contribute to climate change [1].
For example, coal is considered the worst emitter of carbon dioxide.
Nonrenewable Resources
Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy need
6) Energy efficiency is using technology that requires less energy to perform the same function. ... Energy conservation is any behavior that results in the use of less energy. Turning the lights off when leaving the room and recycling aluminum cans are both ways of conserving energy.
7) Living organisms must take in energy via food, nutrients, or sunlight in order to carry out cellular processes. The transport, synthesis, and breakdown of nutrients and molecules in a cell require the use of energy
Organisms use energy to survive, grow, respond to stimuli, reproduce, and for every type of biological process. The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move.
Answer:
Explanation:
1)potential energy is the energy a body has do to its position such as ball dropped from a tower due to potential energy it accelrates towards the ground
kinetic energy is the energy caused by movement remember the ball falling from the tower as it falls it starts attain kinetic energy due to its movement to the ground thus a falling body loses potential energy as it gets close to the ground increases its kinetic energy
2)the excess of anything is bad the exessive use of non renewable is very bad as these resources are non renewable an we cannot use them after they are finished this will become a big problem for example if coal ran out half of our factories would be out of business and the coal products like coal tar are not available so we should conserve non renewable sources of energy
3)energy conservation is saving energy by not using it when it is not neccesary but energy efficency is the process by which energy could be made to do more things to save energy
4)living things use energy in different situations such as digestion exercise etc
