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 major part in order to reduce greenhouse gas emissions due to the fact that five sixth of global carbon dioxide deposit originated from energy generation (Victor, 2011, 116). Clean energy such as wind turbines, hydroelectric plants, and solar energy has been implemented in many countries. For instance

rates, wind power has become a safe and reliable energy source. With ever-increasing economization of generating electricity using wind power, the costs are becoming comparable to that for coal-fired generators and are lower than petroleum-fired and nuclear generators. Taking into account the intermediary investments in environmental protection and transportation, it is more economical to use wind power in place of coal to generate electricity. In addition, the construction of wind power stations takes

They might need to reduce the amount of energy that we use or they could build more energy facilities. They could also balance out the different power sources making it more even and not to worry about losing electricity. Also the other disadvantage of renewable energy sources is the reliability of supply,. The energy often relies on the weather for the power source that we use the hydro generators need rain to fill the damns which supply flowing water, the wind turbines need wind to make the blades

atmosphere. Major pollutants and where they come from Carbon monoxide is a colourless gas that is set free when wood, petrol or coal are not completely burned. It is also in products like cigarettes. Because of it , less oxygen enters our blood and it makes us confused and sleepy. Carbon dioxide is a greenhouse gas that gets into the atmosphere when we burn coal , oil or wood. Chlorofluorocarbons (CFCs) are gases that come from air-conditioning systems or refrigerators. When they get into the

pollution from homes, factories, power stations and cars. The term used to describe this problem is “acid rain”. Acid rain hasn’t just occurred in the last twenty to thirty years. In fact a chemist named Robert Smith found rainfall in Manchester, U.K., to be very acidic. He suggested a link between acid rain and SO2 given off when coal was burnt by local factories. This was over 100 years ago. Acid rain is caused when pollutants from cars, homes, factories and power stations mix with atmospheric

sharing free of service during the heat wave. * Transport France’s national and city train system is regularly dealing with significant delays during the summer months due to the extreme heat which caused the metal railway tracks to expand and power cables to deform. Hence, trains are forced to move at a slower pace resulting in heavy delays. A quick temporary solution to this event declared by the national SNCF is to deploy extra staff to quickly resolve technical problems, and distribute bottles

Rise of Carbon Pacing global economy and industrialization pressurized world to increase its fossil fuel consumption from 4.9 TW in 1965 to 13.62 TW in 2006. The immense increased in HC based Fuels has resulted in large amount of Carbon Dioxide emission. This Green House gas (GHG) attributed to the environmental warming and resulted in an increase of 0.74 degree for past 100 years. Rising global temperatures will cause sea level to rise and alter local climate conditions, affecting forests, crop

space as our population increases.As a result we are disrupting the habitats of animal species that live in undeveloped areas. As we expand our range to make room for new communities we inadvertently displace the natural order of insects, animals and plants that occupy the land. Our attitude towards growth and technology serves human needs and comfort at the expense of animals, organism and the ecosystems that sustain them. Our reliance on technology is hurting the environment at an unprecedented remarkable
