At present, a large part of man’s energy requirements is covered by products of vegetal origin. Fossil fuels (coal, oil, natural gas) have formed from the partial decomposition of organisms – mainly vegetal – that lived over one hundred millions years ago (see the Section on ENERGY). When petrol burns in a car engine or methane burns in the kitchen stove, some of the solar energy trapped by the plants in distant times through photosynthesis is released. Talking of fuels, let’s not forget firewood, which now is no longer used in industrialised countries, but which in developing countries is still one of the main energy sources for the home (cooking and heating).

Facts
Eni S.p.A. - P.IVA 00905811006 What energy comes from plants?Most life on Earth depends on photosynthesis. The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar).
What energy source comes from plants and animals?Biomass—renewable energy from plants and animals
Biomass is renewable organic material that comes from plants and animals.
What is a plants fuel source?The walls of plant cells are made up of three molecules: cellulose, hemicellulose, and lignin. The cellulose and hemicellulose are filled with sugar building blocks that can be used as an energy source.
Is energy in plants a source or form?Plant materials are already used as an energy source through bio-fermentation. Now it appears that living plants can also contribute to energy production. In a plant microbial fuel cell, living plants work together with micro-organisms to create electricity.
