The energy for the TV comes from the electrical connection it makes to the mains.
Some radios (called crystal radios) can operate using only the energy in the broadcast signal, but all TVs must be connected to a power source, usuallly the mains.

What energy refers to energy sources that release very small amount of greenhouse gases?
Renewable energy. (Our manufacture [and consumption] of flat-screen TVs needs an extremely potent GreenHouse Gas! - only a mere 98.8 percent of it is recovered.)
What is the energy transformation that takes place in a television?
Simple answer: Electrical energy comes in and heat, light and sound energy goes out. There are two input sources, the electromagnetic signal that is the actual information of what is to be displayed and there is also the electric power provided to operate the television. Typically, the power comes from an electrical cord plugged into the electrical outlet on the wall and the signal is a cable from an outside source or an antenna. The input energy is electrical energy to power the TV and the signal is electromagnetic energy. The output of primary interest is the image on the screen which is light energy, so the television puts out light energy which is also electromagnetic energy. The television may also produce sound, in which case there is sound energy put out. In the process of making light and sound, the components of the television heat, so heat energy is put out. Summary: Input: Electrical energy enters in two forms, electromagnetic signal and electricity. The electricity is the far greater source of energy. The energy in the signal is tiny. Output: Heat, light and sound exit the television. Heat is the largest and in excess of 90%. Sound energy will be substantially greater than the amount of energy contained in the light.
What does a TV use for electricity?
A TV set is usually plugged into the wall outlet, so it gets the electricity the same way that any electrical device in your home does. The source of the the electrical energy can be coal plants, nuclear power plants, wind farms, solar energy, etc.; but it is usually some mix of these and other sources.
What is the origin of non-renewable energy sources including how energy can be trapped in these sources?
what is origin of non-renewable energy sources, including how energy became trapped in these souces
Can you use energy sources in a sentence?
How about: 'Energy sources are essential for an industrial economy'

Why is there a sudden power surge after turning on a TV?
Because the TV is using power to turn on so the lights may flicker because the TV is taking power from the other energy sources around it.

What energy is the energy in when you get it?
The Energy is used for various reasons such as domestic and industrial use. It is required to produce light, heat, turning an industrial machine, to cook food, to produce electricity that powers all electrical appliances such as televisions, refrigerators, irons etc... sources : http://www.energy-solars.com

What are the different energy sources that are used to deliver energy to your community?
The energy sources that I am most excited about all have lower carbon emissions, compared to conventional energy sources. These include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, and Hydroelectric Energy sources.
