energy plays an important role in saving natural resources and protecting environment. Biogas is a renewable energy source and it can be produced from raw materials such as human‚ animal and plant waste. In order to harness biogas effectively‚ it is important to use advance technology to improve the efficiency of using biogas. Two American utilities have found the purification technology that turn organic waste and gas from sewage plants into natural-gas which can serve the local people. (Rosenthal

is truly a real thing or something that is made up and made to make us worry. Over the last few years‚ we have seen an increase in weather phenomena’s such as snow‚ floods‚ hurricanes‚ and droughts. The debate is if the cause of these events is a natural process or not. The way our planet is warmed is by the sun; the sun’s heat rays are absorbed by greenhouse gasses‚ and become trapped in the atmosphere by greenhouse gasses‚ such as water vapor‚ carbon dioxide‚ and methane. If there were no greenhouse

In ancient Babylon there are writings of a dark elixir oozing from the lands surface‚ even then the people understood how precious this material was. Oil‚ along with Natural gas‚ are exceptionally rich sources of energy. A gallon of oil surpasses the output of five kg of coal‚ ten kg of wood‚ and over fifty times the amount of energy that fifty humans can produce. The richest oil can actually provide one hundred more times

temperature has risen by 0.76° C since 1850. Most of the warming that has occurred over the last 50 years is very likely to have been caused by human activities. In its Fourth Assessment Report projects that‚ without further action to reduce greenhouse gas emissions‚ the global average surface temperature is likely to rise by a further 1.8-4.0°C this century‚ and by up to 6.4°C in the worst case scenario. Even the lower end of this range would take the temperature increase since pre-industrial times above

There are three major forms of fossil fuels: coal‚ oil and natural gas. COAL Coal is made up of carbon‚ oxygen‚ hydrogen‚ nitrogen and some amounts of sulphur -Three main types of coal: • Anthracite : the hardest and has the most carbon in it‚ meaning higher energy content • Lignite: softest‚ low in
