Energy Thermodynamics is, the everything that happens due to the flowing of the heat from a hot locale to a cold locale, and nothing occurs without the flow of the heat. Additionally, thermodynamics is an exact science. Thermodynamic system is defined by volume, pressure, temperature and chemical make-up. When conditions change the thermodynamic system will respond by changing its temperature, volume, pressure, or chemical make-up and will adjust accordingly in order to reach its original state of equilibrium. There are three laws of thermodynamics in which can follow in order to return to equilibrium. I will be discussing the 1st and 2nd law. The first law of thermodynamics is the law of conservation of energy and matter. In essence, energy can neither be created nor destroyed; it can however be transformed from one form to another. We rely on electricity to turn on our lights. Electricity is a form of energy; it is, however, a secondary source. A primary source of energy must be converted into electricity before we can flip on the lights. For example, water energy can be harnessed by building a dam to hold back the water of a large lake. If we slowly release water through a small opening in the dam, we can use the driving pressure of the water to turn a turbine. The work of the turbine can be used to generate electricity with the help of a generator. The electricity is sent to our homes via power lines. The electricity was not created out of nothing; it is the result of transforming water energy from the lake into another energy form. The second law states that isolated systems gravitate towards thermodynamic equilibrium, also known as a state of maximum entropy, or disorder; it also states that heat energy will flow from an area of low temperature to an area of high temperature. Consider a situation where a person takes a very long bath. Immediately during and after filling up the bathtub, the water is very hot -- as high as 120 degrees Fahrenheit. The person will then turn off the water and submerge his body into it. Initially, the water feels comfortably warm, because the water 's temperature is higher than the person 's body temperature. After some time, however, some heat from the water will have transferred to the individual, and the two temperatures will meet. After a bit more time has passed, because this is not a closed system, the bath water will cool as heat is lost to the atmosphere. The person will cool as well, but not as much, since his internal homeostatic mechanisms help keep his temperature adequately elevated. There are some pros and cons to the following energy types.

Fossil fuels is reliable and low in cost, opposed to the unreliable wind and solar energy sources. They are also produce a large amount of energy, all types of machinery, vehicles and devices depend on fossil fuels. The problem with fossil fuels, is that they contribute to global warming, due to their large amounts of carbon. The health effects of our human population is at stake from the pollution from cars that can cause serious respiratory and lung …show more content…
Solar energy is renewable energy source; we will not run out of solar energy as long as the sun is still shinning for another 3 billion years. It reduces our utilities bills, and the amount you save depends on the size of the solar system. The cons are the cost of the solar system, it’s high, solar panels, batteries, inverter, wiring and installation. The weather plays a major role even on a cloudy or rainy day energy is collected, but during this time the efficiency decreases, this also includes during the night time.
Wind Power Advantages and Disadvantages Wind power is obtained by the wind in our atmosphere and then it’s converted into mechanical energy followed by electricity. Basically, wind is free and wind turbines. In addition, wind power does not release pollutants and greenhouse gases into the environment and it only requires a small amount of land. The first disadvantage is, that the wind is not continuous and may not produce electricity. The second, wind turbines are huge and noisy. This nonrenewable resource can never be depleted.
