I assume you mean electricity produced by burning coal, natural gas, or oil. These are the traditional fossil fuels used to produce heat, steam, and hence electric power.
No there isn't No there isn't
Probably the question refers to the sources which provide most of our electricity, like coal and oil, hydro, and nuclear.
Hydroelectric energy uses water. Thermal energy uses heat. Simple Science! Duh!
Cost per unit of electricity depends the type of generation used. ie:- thermal hydel, nuclear etc. hydel electricity is cheaper and now a days it cost less than Rs.10 per unit in India. whereas thermal electricity cost less than Rs. 20 per unit
No, polythene is a plastic and that cannot conduct electricity.
thermal means coal.with coal it produces electricity. this electricity is thermal electricity.
This is difficult to decide I think. It has been available for 50 years now - does that make it conventional? It is a well established and reliable energy source.
Yes, it is can be used as electricity by lighting etc.
THERMAL
Thermal
yes
Conventional Electrical theory (simplified) states that electricity flows from positive to negative in contrast to Electron Theory which supposes negative to positive flow of electrons.
Like all metals, it conducts heat and electricity.
To produce electricity by the use of thermal energy in the form of heat.
no.
Thermal energy is caused by electricity it gives off heat.Again 90% sure
Non Conventional Source of Energy
