The wood is made of organic carbon compounds produced when the tree grew, using carbon from the carbon dioxide CO2 in the atmosphere and energy from the Sun's light to split the carbon from the oxygen.
When the wood is burnt the carbon is recombined with more oxygen from the atmosphere to produce more CO2, and the original energy which came from the Sun is then released as heat.
What else can I help you with?
What type of energy was originally stored in wood?
Chemical energy.
Does geothermal energy originally come from the sun?
No it doesn't because geothermal energy originally comes from the ground!
What is the starting energy of a wood on a log fire?
It is the release of the chemical energy stored in the wood - however remember this chemical energy was originally trapped form the sunlight as the tree grew, so the ultimate source of the energy is the Sun.
Where did the energy in wood originally come from?

Where does hydroelectric energy come from?
it comes from the sea or rivers originally.
How many joules of energy are in a kilogram of wood?
On average, wood contains about 16-20 megajoules of energy per kilogram. This energy comes from the combustion of the wood, which releases heat.
Where does hydroelectric power energy come from?
it comes from the sea or rivers originally.
When wood burns the thermal energy comes from the what stored in wood?
The main component of wood is cellulose made of carbon, oxygen, and hydrogen. The combustion formula is (C6H10O5)n + n6O2 -> n6CO2 + n5H2O + energy ; where n is an positive integer. The energy produced in the equation is used mainly as thermal energy. The energy comes from the net change in bond energies. Since there is more bond energies in the reactants than the products, energy is released. The conservation of energy must maintain equal amounts of energy before and after a reaction.
Is fuel in the form of wood an indirect source of solar energy?
No. Solar energy comes from the sun.
Where did the energy in the rice originally come from?
The energy in rice originally comes from the sun. Through the process of photosynthesis, rice plants convert sunlight into chemical energy stored in the form of carbohydrates like starch. When we eat rice, we are essentially consuming that stored energy.
Where does all energy in a ecosystem originally come from?
The energy in an ecosystem originally comes from the sun. Through the process of photosynthesis, plants and other autotrophic organisms convert sunlight into chemical energy that is then transferred through the food chain to other organisms in the ecosystem.
Is wood renewable or nonrenewable energy source?
Wood is considered a renewable energy source because it comes from trees that can be replanted and regrown. As long as trees are harvested in a sustainable manner, wood can be continually replenished.
