Depends on the context - however with stellar fusion much of the energy is carried away by nutrinos. These fundamental particles have very little mass (almost undetectible) and pass through ordinary matter. Trillions of nutrinos have passed through your body while you were reading this answer.
Only about 10% of the electrical energy used to light an incandescent bulb is converted into light energy. The rest is mostly given off as heat.
Heat energy is a wasted form of energy given out by a hairdryer. A significant amount of the electricity consumed by a hairdryer is converted into heat to dry the hair, making it an inefficient use of energy.
The total energy input can be calculated using the formula: Energy input = Useful energy output / Efficiency Substitute the given values into the formula: Energy input = 20 / 0.25 Energy input = 80 units.
The energy used when pushing something is typically muscular energy, converted from the chemical energy stored in our muscles. This energy is used to apply a force to move an object in a given direction.
When energy is given off by splitting atoms, it is converted from nuclear energy to thermal energy. This thermal energy is then used to heat water and turn it into steam, which can be used to drive turbines and generate electrical energy, converting the thermal energy into mechanical and then electrical energy.

Only 40% of energy is converted to useful work. The rest is given off as heat to maintain homeostasis
I've given a couple links below to articles that can answer your question.

Photosynthesis gets its energy from the light given off by the sun. Light is made up of photons which are little "packets" of energy and this energy is converted to usable chemical energy through the process of photosynthesis.
Most energy is given off as heat, which is a form of energy that is transferred from one object to another due to a difference in temperature. When energy is transferred or converted from one form to another, some amount of energy is usually lost as heat.
The energy transformation occur in toaster is electricity is converted into heat.Electric energy to heat energy. If a toaster is turned on and active by electricity, there is heat given to burn whatever bread or toast you are toasting.
Clearly, that depends on the amount of potential energy. If given the height, calculate the potential energy with the formula for gravitational potential energy (PE = mgh). If mass is not given, you can assume any mass (it doesn't affect the result), or use a variable "m". Then, assuming it gets converted to kinetic energy, use the formula for kinetic energy (KE = (1/2)mv2), replace the KE with the energy you calculated before, and solve for v (the speed).
