total energy used, primarily through heat (Law of Conservation, n.d.). Fossil fuels such as oil, natural gas, and coal were formed many hundreds of millions of years ago before the time of dinosaurs, hence the name fossil fuels (Where Fossil Fuels Come From , 2012). Coal actually provides one-fourth of the world’s commercial energy consumption and when over consumption happens, coal causes air pollution. The burning of fossil fuels emits carbon monoxide,

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 during WWII to create a bomb that would scare the world into peace Nuclear power is used in many ways to create power and to this there are many advantages and disadvantages

rampantly. Being the first of the many countries to transform, the British were considered to be an economic power and unrivalled. Nationalism, on the other hand, implies the highest degree of patriotism where the citizens of a country put their nation’s interest before the others. In the twentieth century, nationalism was plenty especially amongst the citizens of the traditional great powers including the British. Colonialism implies the powerful nations seeking raw materials for their industries

Nuclear power affects our lives in many ways that we do not often think of. With fossil fuels becoming more scarce and expensive each year, this efficient form of energy production is rapidly becoming a critical process. Most power plants could be considered a steam powered engine, except the initial heat source is entirely different. Rather than use nonrenewable sources such as coal or wood, nuclear plants generate heat by firing neutrons at the nucleus of an unstable uranium-235 atom. The atom’s

GLOBAL WARMING Introduction Global warming begins when sunlight reaches Earth. The clouds, atmospheric particles, reflective ground surfaces and ocean surface then reflected about 30 percent of it back into space, while the remaining is absorbed by oceans, lands and air. This in turn heats the planet’s surface and atmosphere, making life possible. As Earth warmed up, this solar energy is radiated by thermal radiation or infrared heat, traveling directly out to space, thus cooling the Earth. However

Figure 1.1 shows production of electricity in Pakistan by different sources. 29.9% electricity is produced by hydro power plants, 35.2% from oil, 5.8% from nuclear, 29% from natural gas and 1% from other resources. It is widely admitted by all parties that Pakistan is entering a period where energy demand is exceeding readily available supply. Electricity supplies are already falling behind demand during peak periods which is leading to rolling blackouts. Pakistan is currently facing a serious

Renewable Energy Summary Renewable energy flows involve natural phenomena such as sunlight, wind, tides, plant growth (biomess) and geothermal heat. According to the International Energy Agency (2002), “Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal
