Significance of fuel wood, non-renewable fossil fuels (coal, oil and natural gas), renewable energy supplies (geothermal, wind, running water, solar and bio fuels)

Fuel wood is fuel made out of charcoal, firewood, chips, pellets, sheets and sawdust. Wood has been and always been the most easily available form of fuel throughout the world and the best advantage of wood is that you do not need any tools, in case you are picking up dead wood and few tools when you have to take it from a source. You will need complicated vehicles and tools like skidders and hydraulic wood splitters to enable mechanised production. The waste obtained from sawmills and construction industries also can be used as fuel.

Wood as Fuel Source

Using wood as a fuel source has been an age old practise and burning wood is the largest use of energy obtained from solid fuel biomass. The fuel from wood can be used for cooking and heating and this source of energy can be used for fueling steam engines and steam turbines which produces electricity. Wood can be used indoors in a furnace, fireplace and stoves and outdoors in campfire, bonfire and campfire etc. As per studies 2/3rd of the world population cooks and heats on wood or charcoal and wood are considered as a more important energy source than oil. It has the disadvantageous also on forest and the trees are illegally cut down to sell commercially.

Many trees are cut illegally for growing other crops like soya, cane, corn etc for bio fuel production. Authorities are finding it difficult to stop this because a lot of people have an income from cutting down trees and sell as wood or charcoal to the city crowd. Fossil fuels are formed by natural process like decomposition of dead organisms. This fuel contains high percentages of carbon which include petroleum, natural gas and coal. Renewable energy is the other form of energy which has become common in the world today. It is the energy which comes from resources like sunlight, rain, wind, waves and geothermal heat.

Renewable Energy

Renewable energy has started replacing the conventional energy in areas like electricity generation, space heating, water heating, motor fuels and rural energy services. Renewable energy like hydro, wind, solar, bio-fuels and traditional biomass have contributed to the global energy supply. The overall worldwide investments in renewable technologies have gone up in the year 2013 and 2014 and are expected to gone further up. The resources of renewable energy have wide geographical coverage when compared to other energy sources and people all over the world are supporting the promotion of renewable sources like solar power and wind power.

Many companies of international repute have got into the renewable energy projects in large scale but the renewable technologies is suited in rural and remote areas and developing countries also. Fossil fuels can be called renewable resource because they are continually formed through natural processes like plants and animals but they fall under the non-renewable resources because it takes millions of years to form. Renewable energy is definitely the future because the energy produced is made out of natural resources and there is no shortage of sun and wind energy in the world.
