Solar energy and environmental impacts Research Paper

Solar energy and environmental impacts - Research Paper Example Solar energy is copious in the earth and it suggests important potential for the alleviation of climate change; therefore, it is desirable due to its inherently small burden on the environment and has opportunities for positive social impacts. This is further helped by the fact that the cost of solar technologies has been reduced to significant proportions and technical advances coupled with favorable public policies that has resulted into reduction of costs. The use of solar technologies has the advantage of having low lifecycle greenhouse gas emissions when compared to other forms of fossil fuels. This is because the production of solar energy through the photovoltaics (PV) emits no pollution nor does it emit greenhouse gases (Fell, 2012). Moreover, it has the effect of improving the health and livelihood of most of the world’s poorest neighborhoods as it addresses the gaps that is not filled by the available modern energy services (IEA, 2010). Environmental Impacts A report by The Wall Street Journal stated that the development of solar on lands that are deemed desert by disturbing the caliche deposits found underground leading to the release of carbon dioxide in the atmosphere. A similar study has equally found that the development of a solar plant could cause emission of about 6000 metric tons of carbon each year from the disturbance caused by the plant (Wall Street, 2010). Forests play a crucial role in the life of both plants and animals and hence any form of deforestation hinders the proper functioning of these species thus damaging the atmosphere. The role played by forests in human life cannot be gain said and therefore when they are cut to create room for solar plants, the absorption of carbon dioxide ceases or the carbon stored in the trees is released into the atmosphere when the tree is left to rot or is burnt. This has the overall effect of occasioning carbon dioxide build-up in the atmosphere that eventually leads to climate change. This is what happens during the installation of large-scale solar-power projects as ecosystems are interfered with when huge tracts of land are put in use. Forests have to be cleared to prevent shading of solar panels and allow for easy installation of solar posts. The removal of the forests thereafter leads to a change in the natural carbon sequestration rate that thereafter affects the amount of carbon dioxide emitted in the atmosphere. It is important to note that land use will ultimately affect the climate of a place including the local climate, microclimate and the temperature of the surface of land. Therefore, when solar panels which usually have low reflectivity and utilizes or converts large amounts of solar insulation into heat, there is the likelihood it may affect the global climate or the climate of a particular place. To minimize the effects that come about because of land use, it is important that when a solar installation is to be put in place by any stakeholder, the land selected should be in areas with low population density that translates into a low environmental sensitivity. Solar Energy and Climate Change The use of solar energy has an advantage in the sense that carbon savings derived from the use of solar energy outweighs the development of this form of energy. This means that a solar plant can save nearly 560, 000 metric tons of carbon per year (Wall Street, 2010). There is therefore a need to expand the solar power potential in order to meet the climate
