Energy Usage Of The United States

Good Essays

Here in the US alone we consume nearly 6.844 Quadrillion Btu’s of energy, however most alarmingly less than 7% of our toll energy usage comes from Alternative energy resources. This leads to the edge of a dangerous presuppose as our current resources continue to dwindle and our future grows darker each day. It is estimated that there is less than 200 years of oil left in the reserves we currently have and with the population and the demand for oil increasing each year it could be here faster then we know it. As we continue to pour pollutants back into our skies, waters and lands each year our planet feels the effect each day.
Every year in the US alone our factories spew over 3 million metric tons of chemicals back into the environment …show more content…

Solar power is the most abundant most renewable resource that we have and it is free. The process starts when the sun shines on Solar PV panels that have been installed on your roof. Photovoltaic refers to the scientific process by which solar energy is converted into electricity. There are a number of silicon cells within each PV panel. These react with photons, or units of light, from the sun to produce direct current or electricity. DC electricity then travels to an inverter, which converts this energy to electricity known as alternating current or AC that can be used in your home or office. AC electricity then travels to the distribution network in your home powering your domestic or office appliances. When your solar panels produce more electricity than your home or office is using, the extra electricity gets fed back into the national grid. Yet, there are many processes the PV cell actually goes through to produce power of electricity. The top and bottom layer of the PV cells are protective glass layers with conducting coding’s. Electricity in the form of electrons flows in and out of these conducting coding’s while electrical production process happens in the middle layer of the PV cell. At the molecular level, a photon strikes a dye molecule absorbed on the surface of the TiO2 causing an excited state, which releases an electron into the TiO2 that exists through the conductive layer.
