Which renewable energy source was first used by humans?
The first renewable energy source used by humans was likely wood, as it was used for heating and cooking thousands of years ago.
Is charcoal energy?
Charcoal is a form of energy that is obtained by burning wood or other organic materials in the absence of oxygen. It can be used as a fuel source for cooking and heating.
What is the energy transformation taking place in solar cooker?
Radiant energy -> electrical energy -> thermal energy
What 2 broad categories of pumps are commonly used as the energy source in a liquid system?
Positive displacement pumps and centrifugal pumps are the two broad categories commonly used as the energy source in a liquid system. Positive displacement pumps provide a constant flow rate, whereas centrifugal pumps generate flow through the conversion of rotational kinetic energy to hydrodynamic energy.
What items use heat energy.?
Cooking uses heat energy as the main source. It is the main activity that uses heat as a source of energy.
Is Solar Energy commonly Known source of energy?
Yes.
What does propane do for someone?
Propane is a gas commonly used as fuel. Households use propane for both cooking and heating purposes. Propane is a popular fuel source because of it is relatively inexpensive and very easy to obtain.

The first renewable energy source used by humans was likely wood, as it was used for heating and cooking thousands of years ago.
How do you use electricity for cooking?
Electricity is a viable source of heat element for cooking. When electrons are mixed with energy, they create friction hence heat to cook with.
Is kerosene a primary fuel?
Kerosene is considered a primary fuel, as it is derived directly from crude oil through the refining process. It is commonly used for heating, cooking, and as fuel for jet engines. While it can be converted into other forms of energy, its primary role is as a direct energy source.
Which energy source is the most widely used for heating and cooking in rural areas of South Asia?
wood
Where is fission commonly seen?
Our sun. The source of solar energy is due to nuclear fission.
