Hydrocarbons are part of fuels such as petrol, diesel and gaseous fuels such as paraffin gas.
They are released in the atmosphere whenever they are 'released' without being burnt! For example, petrol drips on to the forecourt at every refill and evaporates into the atmosphere.
An example from within an engine is when the spark plug ignites the fuel-air mixture, a tiny fraction of the mixture remains unburned and is released in the exhaust emissions.
Hydrocarbons are found in crude oil whick is black and thick. to find out how crude oil was formed look on the formation of oil
From bonding energy.
the energy stored in an unlit candle is chemical potential energy, and it is stored in the bonds between the atoms in the hydrocarbons (wax) that make up the candle.
This is the heat of combustion.
the advantages are that it gives of heat and energy. the disadvantages are that it is not easily stored
Screw you and your biology.
Covalent bond between Carbon and Hydrogen store considerable amounts of energy,hydrocarbons make good fuels. Gasoline for example is rich in hydrocarbons.

Gasoline is a mixture of hydrocarbons. As gas is burned, the compounds are broken down into simplier compounds and the breaking of these compounds releases energy.
When the trees and vegetation were growing they took in solar energy through photosynthesis. This energy was stored in the plants as hydrocarbons. It remains there as the plants, over millions of years, become fossil fuels (coal, oil and natural gas).

Chemical energy, stored in the fuel.
Chemical energy, stored in the match.
No! Diesel is a product of hydrocarbons, which deposits are limited and therefore not renewable energy source.
It is stored in the atom.
From the energy stored in light.
As in all hydrocarbons the energy is stored in the covalent bonds that make the compound. The bonds between H-C and C-C The energy is released when these bonds break. The bonds are broken using a little incentive such as fire or a spark in the presence of oxygen.
