Biomass Power Generation 1. Introduction into the current situation The utilization of fossil fuels will be even extended in future due to the still growing number of humans on the world especially in developing countries like China‚ India and most of African countries. [1] This fact is supported by figure 1 which shows the growing of world’s population in future. Figure 1: World`s growing population (Source: Beyond Six Billion: Forecasting the World ’s Population) At present roughly 80% of world’s

Vertical Farming Vertical Farming is a modern way of farming‚ is a concept that argues that it is economically and environmentally viable to cultivate plant or animal life within skyscrapers‚ or on vertically inclined surfaces. Land and population: It is estimated that by the year 2050‚ close to 80% of the world’s population will live in urban areas and the total population of the world will increase by 3 billion people. A very large amount of land may be required depending on the change in yield

print“We are being advised to reduce our carbon footprint. Discuss the significance of this for the individual and for industry” When talking about climate change‚ footprint is a metaphor for the total impact that something has and carbon is shorthand for all the different greenhouse gases that contribute to global warming (1). The term carbon footprint is a measure of the impact our activities have on the environment‚ and in particular climate change. It relates to the amount of greenhouse gases

In present day people all around the world have used many energy sources. For instance‚ cars have to use much fossil fuel energy. Coal and natural gas also have been used too much to heat homes and businesses even during the winter (Adapted from Rosenthal‚ E. ‚ 2010‚ December 11). As this information‚ ‘finding alternative energy sources is one of the major projects of this century in all countries because the world is running out of the natural resources’ (Edited extracts from authentic student

ENERGY RESOURCES Energy is defined as ‘the capacity to do work’. Sun is the primary source of energy. Joule is the standard unit of energy in SI units. Energy utilization is an index of economic development‚ which does not take into account of ill effects/damage on to environment. From 1900 to 2000 population increased by 3 times while energy consumption by 14 times! Energy Resources All energy sources ultimately come from the sun‚ the moon or the earth. Sources of Energy Solar

Sources of Energy When we use energy in its usable form we convert the form of energy and get our work done during the process. Since we cannot reverse the change involved in this process so we cannot get back the original usable form of energy. Due to this‚ it becomes important to think about energy shortage and the related energy crisis. Characteristics of a good source of energy: It should be able to do large amount of work for each unit of mass or volume. It should be easily accessible

Landfill gas is generated during the decomposition of organic substances in municipal and industrial wastes. Since it is made up of powerful greenhouse gases‚ primarily methane gas and carbon dioxide‚ the prevention of escape to atmosphere is desirable and has the added benefit of being utilised as a renewable energy source (Clarke Energy‚ 2014). One such company focussed on dealing with this issue is Landfill Gas Industries Pty Ltd (L.G.I. Pty Ltd) they are ‘a specialist designer‚ supplier‚ installer

3.MINERALS AND POWER RESOURCES A naturally occurring substance having a definite chemical composition is called a mineral.Minerals are found in certain areas only and not every where. Minerals are formed in different conditions and human activities do not play any role in their formation. Instead only natural processes are involved . Minerals are identified on the basis of their physical properties like colour ‚density ‚hardness and chemical properties like solubility. On the basis of composition

well enough to be called a commodity. The major processes that have successfully transformed garbage into products of economic value are recycling‚ reusing‚ repairing and refurbishing. These products range from fertilizers‚ animal feed‚ energy‚ and biogas. Recycling refers to the process of collecting and processing of materials that would otherwise be thrown away as trash and turning them into new products. Materials that are commonly recycled are steel‚ plastics‚ glass‚ aluminum and paper. Steel
