Assuming you mean electric lights, then eventually the power company. The power company generates power, and sends it over power lines to your home. These are the same power lines that you might see crossing the interstate, or traveling parallel to the city streets. If no power line visibly connects to your home, you might have an underground power line. They're generally much more expensive, but less susceptible to the weather, and much more sightly.
Well the output of any oven should be Heat (thermal energy), with exhaust fumes and gases as (unwanted) secondary outputs occurring in most designs. And the input can be any sort of fuel to produce said heat, depending on the oven. Most commonly, the input of an oven is electricity, gas, oil or wood.

by using solar clees their is no pollution it is eco friendlyThey have no moving parts and hence require little maintenance and work quite satisfactorily without any focusing deviceIt does not cause any environmental pollution like the fossil fuels and nuclear powerSolar cells last a longer time and have low running costsAnswer:Anytime you can harness the sun's energy, you are tied into the most powerful source of energy available anywhere. Solar cells are getting more efficient all the time. These solar cells can be used in so many ways. When at Costco the other day, I saw solar cells that can be taken with you when camping. These cells can be stored in a device that also inverts that energy to AC if needed. You can run all kinds of lights and devices, including your computer.The advantage of using solar cells at home or in a business are many. You can actually produce more energy than you use. When this happens, the extra feeds back into the grid and you are paid for it. It's fun to see your power meter actually run backwards. With all the tax incentives, a solar system can pay for itself in as little as five years. With electric rates constantly rising, that could be worth a small fortune to you in the long run.

There are many typres of energy sources to heat the things like sun light, solar energy , wood, biogas, electricity coal, many types of crude fuels like grass cow dung, etc. One of the humourist poet Athar Shah Khan ( Jedi ) " Oh God give me such a charming neighbour that should warm up my heart " . If the heart is to be heated then you have plenty of heating material on internet. If you want to het up swines from Revene or police then just hesitate to give bribe . Please don't try any heting up in home ministry otherwise you get people in the street quite heated up who would get straight aim of utencils thrown out. Some of pairs try banging the doors if you have steel doors then there is no harm .
LED light bulbs are the most energy-efficient option for your home.
LED light bulbs are the most energy-efficient for home use.
yes... for example electrical energy is converted to heat and light energy in a light bulb

In a home, energy transfers occur when electricity is used to power appliances, lights, and electronics. Heat energy is transferred when the heating system warms up the home or when cooking on the stove. Light energy is transferred when light bulbs illuminate a room.
light and solar
All kinds of energy, some of it being: - Light energy - Thermal energy - Magnetic energy - Electrical energy - Mechanical energy - Gravitational energy
A battery is an example of something that has chemical energy and can be changed into light energy and sound energy. When a battery powers a flashlight, the chemical energy is converted into light energy, and when it powers a speaker, the chemical energy is converted into sound energy.
solar energy can be used to produce electricity.it can also use for home at low level.through this we can heat water
No. The whole idea of a home heating system is to produce heat, not to produce work.
