∙ 13y agoit is useful coz it gives you thermal or electrical energy and is better for the environment
Solar Energy
electricity
Two useful forms of energy that come from the sun are solar thermal energy, which is used to produce heat, and solar photovoltaic energy, which is used to generate electricity through solar panels.
Solar energy saves you money.
not really, because solar energy can be non useful sometimes
it provides energy without burning coal.
False
The energy that is not usefully transferred by solar cells is typically dissipated as heat. This occurs when the energy is not converted into electrical energy due to inefficiencies in the solar cell's conversion process.
Some useful energy transfers include converting solar energy into electricity through solar panels, converting wind energy into electricity through wind turbines, and converting chemical energy in fossil fuels into electricity in power plants.
Useful energy change in the solar cell is from light to electrical energy. Solar cells use the photovoltaic effect to convert sunlight into electricity by absorbing photons from sunlight and generating an electrical current.
Solar heaters are useful for heating water with natural energy, thus saving electricity. The question is can effective solar heaters be made for less cost than using the electricity.
Solar energy is energy, it can't waste energy.The process of converting incoming solar energy into other forms of energy that are more useful to us (which is often, confusingly, still called "solar energy") does in fact waste some of the input energy, since no real conversion process is 100% efficient.
