==== The force of the problem is with the concentration of CO2 is rising. These gasses that are being emitted are causing almost like a big glass bubble not letting the gas to escape. Also with the lack of organism’s dying the fossil fuels aren’t being created at the rate that we need them to keep living off of it. These fossil fuels take millions of years to create and most scientists predict that in the next 50 years we will run out of this valuable substance. These fossil fuels weren’t recently tapped into until a few hundred years ago and up until this point it wasn’t a very big problem. An even bigger problem is how to prevent these emissions of gasses to dramatically decrease. Our personal answer to get a solution is to install more dams, and could drastically benefit the economy as we know it. With this installation of dams jobs will need to be put in place. For both the construction and manual labor needed along with putting more engineers into work. ==== ====Currently in this world the three most used fossil fuels are coal, petroleum and natural gas. Sadly one problem is the exponential rate that the world’s pollution is growing. Rising of CO2 makes the greenhouse effect a lot stronger, CO2 holds heat a lot better and this is the cause of global warming. Global warming means increase in the world’s global temperature, since 1860 the world’s CO2 concentration has risen 25%. The temperature on earth has raised 1.1 degrees Fahrenheit since 1860 as well. Another big problem is the entire earth’s shift towards industrialization, and no country is more staggering then that of China. ====

==== The big thing is what we can do to replace this exponential problem we think would be hydro power. It is a very renewable resource, and generates roughly 777 gig watts. People may not know but this is 20% of the world’s electricity. We are well aware that the only countries located around the water would benefit from this insulation but the countries closest to water are the ones emitting the most CO2. ====

==== Hydroelectricity works from flowing water goes through a hydraulic turbine which converts the energy from the flowing water into mechanical energy. Mechanical energy is then converted into electricity by a hydro electric generator. Faraday discovered the operation of a generator. He discovered the flow of electricity can be caused by a magnet moving past a conductor. Electromagnets are made by rotating direct current through loops of wire wound stack of magnetic steel lamination in a large generator, which is called field poles. Field poles are mounted on the outside of the rotor. ====

====The rotor rotates at a fixed speed and it’s attached to the turbine. When the rotor rotates, it causes the field poles or electromagnets to move past conductors mounted in the stator. This causes electricity to flow and a voltage to develop at the generator output terminals. ====

==== Hydroelectricity doesn’t burn fossil fuels so therefor they don’t directly produce fossil fuels. Hydroelectricity produces the least amount of greenhouse gases. The only CO2 that was produced during the production and constructions of hydroelectric dams was such a small amount. It doesn’t compare to the amount of carbon dioxide in the atmosphere or the amount that is produce by other energy producing plants. ====

==== Hydroelectric dams create reservoirs and mass body of water called lakes. They provide for water sports, family fun and tourist attractions. Some damns are installed for irrigation that supports agriculture and will always have a constant water suppl. Some dams that are built large enough can control floods, which affect people that are living downstream. ====

==== Since hydroelectric dams do not burn any fossil fuels, they don’t emit any greenhouse gases in the atmosphere so it produces energy and saves the Earth from global warming at the same time. The water that is used to produce energy is not removed from the environment or polluted. It runs through the turbine then returns to the river or body of water that it came from. One of the best things about the water is it doesn’t have an electrical charge so it isn’t dangerous to the environment that it is going back out into. Another is the economic advantage eliminating the primary cost to run the turbines with fuel. Also, most plants are still in service after 50 to 100 years after their creation and are automated so they don’t need to have people constantly watching them. This is very vital because, at this school we know, the engineers want the big bucks and constantly needing them could be very bad for the financial stability of the plant. ====

====Our personal reaction to the way that hydro plants work is a positive, they don’t burn off the vital fossil fuels that are being used up at an exponential rate. Also, the fact that very little CO2 is being burned off in this production of electricity.Though in some instances it is true that some contributing factors that do emit some bad gasses. "Those emissions are comparatively small, said environmental chemist Tonya Del Sontro. A coal-powered generating station producing the same amount of electricity as the Aare plant would release approximately 40 times the amount of greenhouse gases, expressed in CO2 equivalents, she said. However, the findings represent an emission source not previously included in greenhouse gas calculations. The methane gas comes from sediment at the bottom of the impoundment that contains high amounts of carbon-rich material. Organic matter is transported to the lake by the River Aare and then undergoes microbial fermentation."(Tonya Del Sonotro.) So you cant deny the fact that some bad gasses will be emitted from such an engine. Only in a perfect world would be able to not emit any though the fact that it will decrease forty times is at least a step in the right direction.====

 In response to, if it is the primary source of energy, it isn’t due to the fact that is can only be built in areas rich in water. Also, it needs the capability of stopping the flow of water and not has a catastrophic disaster in the change of flow. Brazil, Canada, New Zealand, Norway, Paraguay, Switzerland, and Venezuela are all countries that primarily use hydro plants to generate electricity. Paraguay actually uses these plants to receive 100% of their electricity. Since the last 30 years nearly twenty-two dams have been built to produce this electricity. Also, a German institution has modified the system having more cost efficient, with certain flow so the living organisms in the water won't be injured by the production by electricity. =====

production ([|TWh]) ||~ Installed capacity ([|GW]) ||~ Capacity factor ||~ % of total capacity || ====The way it can help solve the problem is to decrease the amount of CO2 emission into the atmosphere along with the decrease in the amount that we are burning off in fossil fuels. Produce enough electricity for the entire world, and it may not solve all of the problems but decrease the general emission. The job production will increase, hopefully decrease the unemployment rate that the nation is currently in. Also, giving jobs in the plants daily even though the plants are automated human power will always be needed.====

====For hydroelectricity to do better for the environment and help to the atmosphere from greenhouse gases and global warming i very unlikely to do. It would take a lot of large amount of very large mass body of waters from every country. It would take land and living areas away from a lot of people too. Lot of countries don't even have a choice to run off hydroelectricity because of the lack of large amount of water. If every country was capable of running a majority of their hydroelectricity then it would help the problem of greenhouse gases and global warming.====

====A lot of countries throughout the world do use hydroelectricity. Some more than others. Some don't use it as much as others because of the lack of water or the conserving of the environment. United States have the fourth most annual hydroelectric production in the the world which is 250.6 TWh but it is only 6% of the energy that is used in the United States for electricity. China has the most Annual hydroelectric production that is 652.06 TWh and it is only 22% of energy that china uses of their electricity. Brazil, Canada, New Zealand, Norway, Paraguay, and Venezuela are the only countries in the world that use majority of hydroelectricity as their energy and it produces over 90% of their electricity. Paraguay actually runs completely 100% of its electricity off of hydroelectricity.====

====Our first change would be to press them more on a small scale level, you can't just throw in the idea of hydro plants then the next year start to build gigantic ones. Start to power towns on the Mississippi or other rivers to prove to the population that it can work. Then slowly build the first one, you can't mass produce these plants, they take time and any miscalculation could become detrimental to all those around it. Their is no doubt this plant could not only help ourselves, with the gasoline and cost of other fossil fuel products but the environment. Though the two of us aren't crazy about the whole global warming concept, a cut back is necessary and this plant would be our first step to saving the world.====
