greenhouse emission. Furthermore, there are various technology and method to reduce carbon emission on the atmosphere. Finally, government policy such as carbon tax has been implemented to combat this issue. Firstly, energy generated by alternative means other than fossil fuel has been developed to reduce carbon emission. The term renewable energy can be describes as a power generated from resources that can be replenished indefinitely (Australian Renewable Energy Agency, 2011a, internet). Energy became

What would happen to our world if our energy unexpectedly disappeared? Fossil fuels are very important to our world because they provide an overwhelming majority of our world energy. So, what happens when they run out? As the world enters a new century, new source of energy such as wind power need to be used more to help the world keep running on all cylinders. According to the American Wind Energy Association, “Wind power captures the natural wind in our atmosphere and converts it into mechanical

Solar power as away of providing heat and electrical energy from heat The Sun the heat of the sun is about equivalent to burning a billion trillion tons of coal an hour. Even though only a small fraction of that heat ever reaches the earth it is still more then enough to power the whole world. People seemed to realize the importance of the sun around 30,000 BC. This was when people first started planting crops of wheat. They realized

natural gases such as CO2, Nitrous Oxide or Methane and are created in one of two ways. The first way is, through natural cycles, for instance, CO2 is released through animal respiration or plant photosynthesis. The alternative greenhouse gas production comes from man’s use of different fuels and products; this can lead to anthropogenic climate changes. Anthropogenic Climate Changes are changes in the atmosphere brought on by human activity, and there is evidence of these kinds of changes all over.

Principal Research Results “Energy Chain”, A New Concept in Evaluating Future Energy Conservation and Greenhouse Abatement Alternatives and Effectiveness Background The energy demand and supply system consists of many kinds of energy subsystems, for example, grid network, fuel (city gas, LPG, kerosene and so on) networks, prospective fuel (hydrogen) networks and demand-side equipments such as heat pump and cogeneration. In recent years, many evaluation methods and factors have been proposed

India by Panhwar. 30million rural households in china that have biogas digesters, these rural areas have many benefits such as saving fossil fuels, saving time, protecting forests, saving money, saving cooking time, improve hygienic conditions, improving the rural quality of life, reducing water and air pollution(Prabhu et al.). Biogas is a kind of bio-fuel and it is derived from biogenic. Biologically break down of organic materials in the absence of oxygen is referred to as Biogas. Organic wastes

But first what causes global warming? Many things cause global warming. One thing that causes global warming is electrical pollution. Electricity causes pollution in many ways, some worse than others. In most cases, fossil fuels are burned to create electricity. Fossil fuels are made of dead

a result, less fuel. However, disadvantages of hybrids include: (a) Lower Power Output Hybrids are usually designed for fuel economy, not power and thus they tend to produce less power than their full fuel counter parts. (b) High Maintenance Costs The complexity of hybrids mean they cost more to maintain. 2. Fully Electric cars are powered exclusively by electric motors. They usually have batteries, where electricity is stored, or collect electricity from an external source. Advantages of these

Terrifying New Math 1. The key message that the author is telling us regarding the fossil fuel supply situation, carbon emissions and global warming is that the amount of carbon needed, from the consumption of fossil fuels, to be released in the atmosphere to increase the global temperature to a point that will have a catastrophic effect on our planet, represents only one fifth of the total estimated fossil fuel reserves worldwide. This means that the threshold we need to stay under to avoid climate
