What machines that create unusable energy?
Is the question 'What machines create unusable energy?' All machines create unusable energy because entropy increases; 'You can't break even. '(C P Snow).
How do machines create energy?
It is wrong to say machines create energy. Machines have to be given energy to make them effective. This could be electric energy, solid liquid or gaseous energy, thermal energy, mechanical energy (like a flywheel for example). It may be possible to design machines which will search for their energy by themselves, some robots may already have achieved. Remember we humans are also machines, but we get our energy from digesting food.
Do machines use power to perform work in a more energy efficient manner?
Yes, a simple machine can create friction, and friction can create heat. You are converting mechanical energy to thermal energy.
What limits the use of wind as a major source of energy?
Turbines and generators in the wind machines create electricity.
How does natural resource like wind work?
There are machines built that harvest natural energy for human use. Some examples include hydroelectric energy, wind energy, and solar energy.
Why should renewable energy not be delayed?
Creating sources of renewable energy, (Hydro dams, Solar Panel, etc) is relatively easy when we have machines to help us. If we wait to create them until after the non renewable energy runs out, we won't have any source of energy to power useful machines, so inferstructure creation will involve huge expenditures of blood sweat and tears.
Is a man starting a shopping cart generating kinetic mechanical energy an example of energy being created?
No. You won't find examples of "energy being created", because it isn't possible to create energy.
Can machines increase energy?
no
What does mechanical energy do?
It is an energy that is done through machines.
What does mechanical energy?
It is an energy that is done through machines.
List several examples of how electrical energy and light energy are useful to you?
Electrical energy and light energy are useful to me in a variety of ways from the machines used to make the food you eat to the energy used to purify the water you drink. The clothes you wear are even dyed different colors from the light energy alone.
What is the ideal set temperature for washing machines to conserve energy?
