Pros/Cons, advantages/disadvantages of nuclear energy/fossil fuels.

Much of the worlds energy is produced from Uranium. This energy is commonly referred to as "nuclear energy" because uranium reacts in nuclear reactors to form heat. When fossil fuels are used for heat, they are just simply burned instead of reacted, so they create only mediocre amounts of heat for the plant. Nuclear power is responsible fore over 11% of the worlds energy, without the enormous amounts of coal or the pollution that fossil fuels …

…third and final disadvantage of using nuclear energy is its thermal pollution. Thermal pollution occurs when hot effluents from a plant are placed into a lake or ocean. This causes the temperature of the water to rise slightly, making the location more favorable to creatures not already there. This problem can pretty easily be solved by cooling these effluents before placing them in the water, making it slightly more expensive but solving this problem completely.
