The law of conservation of energy is a very important foundation to our entire scientific world. It is not "used". It just is. Without it, nothing would work, we would not exist, the universe would not exist.
An efficient transformer will convert more than 99% of the input energy into output energy, therefore wasting less than 1%.

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.
Fuel rods are the nuclear fuel in a nuclear power plant. They are used to turn water to steam, which is then used to turn a turbine. They do not "generate energy", since energy cannot be created or destroyed (E=mc^2). They are used to generate electricity, or to convert nuclear energy to electric energy.
A dam is used for hydroelectric energy.
it used to cook and heat.
Sound is a form of energy. It is created when one speaks.

Two ways geothermal energy is used are for heating greenhouses and homes or businesses.
The burning simulates metabolism of food (peanut) to obtain energy (Calories), which is then used to do work.
Renewable energy is used all over the world.Wind energy is usally most used in the most windy places in the world like mountains.
a cube because its used in the real world plus its not a polygon
Solar energy is used throughout the world for various reasons. Spain, Germany, U.S. and South Korea all use solar energy.
Energy is energy and it comes in two types, real energy and vector energy. Real energy is characterized by the square of the real is a positive. Vector energy is characterized by the square of the vector is negative. If kinetic energy is not real energy it must be vector energy. Real energy is called Potential energy and vector energy is a new term that should be used for kinetic energy. Kinetic or vector energy differs because it is a vector. All forms of energy are either Real or Vector energies. Kinetic connotes motion but the distinction is real or vector. E= mv^2 is a real energy not a vector yet it denotes motion with v a speed.
