Thermo summary essays

Thermo summary essays There are many issues involving the world we live in, one of which is energy. The world uses great amounts of energy each year. As the world is growing the total energy consumption is also increasing rapidly. It is said to rise by 59% from 1999 until 2020, from 382 to 607 quads. This obviously means we have to produce more energy, however if we continue by the same means of production providing 85% of the energy by burning fossil fuels we will also be increasing the carbon dioxide emissions by 60% causing these environmental concerns: smog, acid rain, and the apparent green house gases that will lead to global warming. This would ruin the environment, as we know it. The scientists of the world know this and much research is being done to prevent this from happening. Many ideas have been born to combat this problem. Some researchers in the oil drilling industry have found that petroleum can be extracted from its well by drilling horizontally. This in turn, cuts down on the number of wells needed since it can be obtained from kilometers away. Other researches are designing a more efficient and cheaper way of energy production with a hydrocarbon free process using nuclear power. Hydrogen is another mode to produce energy since it admits low levels of nitrogen oxides and burns very efficiently. When used in a fuel cell it exhausts water, which is obviously not harmful to the environment. Hybrid automobiles are a way to reduce the need for oil. The current fuel-efficiency requirements are 27.5 miles per gallon and 20.6 miles per gallon for new cars and light trucks respectively. The hybrid cars have attained 80 miles per gallon which is more then double the standard cars. Natural gas was an idea to cut the carbon emissions, however to it would be t erribly expensive to fulfill the needs of the world, due to the fact that it is extremely expensive to transport from the reserves. The natural gas would need to be c...
