Solar energy is stored in coal and petroleum.
Use coal less
Coal is a form of energy created by burning the coal that is mined. Coal is part of the problem because of the greenhouse ases created by burning it. If we continue using coal at the current rate we will soon run ot.
Yes coal was formed by the bio materials of forests and swamps and the energy as now came from the sun.
One of the uses of coal is for power.
Useful energy transfers in the production of electricity using coal occur when heat from burning coal is used to generate steam, which drives turbines to produce electricity. Non-useful energy transfers include heat lost through exhaust gases and in the cooling process of the power plant, which reduce the overall efficiency of the energy conversion process.
when coal burns the energy change is chemical -------------> electrical
When coal is burnt, some of the energy is wasted as heat in the surroundings, through processes like conduction, convection, and radiation. Additionally, some energy is lost as sound and light energy, which do not contribute to the useful work being done.
When coal is burnt, the energy lost in the form of heat and pollutants such as carbon dioxide and ash is considered as not useful energy. This includes waste heat that is not converted into useful work or electricity.
One type of energy released and not useful when coal is burnt is thermal energy in the form of waste heat. This energy is often lost to the environment in the process of burning coal and is not harnessed for productive use.
it provides energy without burning coal.
One of the energy releases that isn't useful when coal is burned is thermal energy in the form of heat that is lost to the surrounding environment, rather than being converted into useful work or electricity.
By burning it, which produces heat
Chemical energy is transferred to electrical energy! :) :p
Solar energy is stored in coal and petroleum.
When coal is burned, the useful energy transfer is in the form of heat, which is typically used to generate electricity in power plants. The heat produced by burning coal is used to heat water and produce steam, which then drives turbines to generate electricity.
The wasted energy when coal is burnt is called waste heat. This is the energy that is not converted into useful work during the combustion process and is released into the environment as heat.
