Greening Transportation Role In Tackling Global Warming What is global warming? It is a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. These gases are emitted into atmosphere mainly by human activities. Global warming has been a major concern nowadays, because the average global temperature is climbing significantly. The production of carbon dioxide and other

Introduction 1. [pp: 2Albert]Albert Einstein once said: “The release of atomic energy has not created a new problem. It has merely made more urgent the necessity of solving an existing one.” 2. Nuclear power is a source of energy that occurs when a neutron is launched at an unstable atom like uranium or plutonium. A cool fact about nuclear power is that it is a scientific discovery that was funded by the military. The US called it the Manhattan project. The project existed

Geothermal Energy is the use of the energy in the earth, the natural heat the earth produces. There are several ways to harness this power, and frequently these sources are totally renewable and re-usable. These natural alternatives have been preferred by many over using the fossil fuels so prevalent in society at this time, in that they can be used without the environmental arguments presently going on about fossil fuels. Geothermal energy was first discovered in the seventh century, when
