Energy plays an important role in the national security of any given country. Threat to energy security can also result to economic and other threat which can lead to physical damage to the energy infrastructure (such as pipeline vandalization), natural events, insurgency or warfare. The political and economic instability caused by crisis and other factors such as strike action can also prevent the proper functioning of the energy industry in the country. In recent years, new threat to energy security has emerged in the form of the increased world competition for energy resources and concern on climate change and the negative environmental impact of excessive fossil fuel consumption. Long term measure to increase energy security centre on reducing…show more content…
It is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources. In order to understand better the various forms of energy, the sources of energy may be divided into three broad categories. These categories are renewable, non renewable and non depletable energy sources. A renewable resource reflects a perception of time. A resource is renewable if it can be replenished at a rate that allows it to be used in a significant or commercial manner. While there is no limit on the total quantity of energy humans can obtain from a renewable resources, there is a limit on the rate at which energy can be extracted. Thus, renewable energy sources are effectively exhaustible if they are not managed to ensure…show more content…
The key benefits which are that renewable energy technologies are clean sources of energy that have a much lower environmental impact than conventional energy technologies. For example, A renewable energy system transforms in coming solar energy and its primary alternate forms (wind and river flow), usually without pollution –causing combustion into readily usable form of energy such as electricity. Renewable energy does not run out ever. Other sources of energy are finite and will someday be depleted. Some renewable energy forms are: Solar, Wind, Micro hydro, Fuel cells, Biomass and Geothermal energy. However, some energy forms are non-renewable. Major non renewable energy forms are the Fossil Fuels. These are the traditional sources of energy such as coal, oil and natural gas. Fossil fuels are non-renewable since they cannot be recycled. Once they are spent they cannot be recovered again. Renewable energy is sustainable indefinitely, unlike long-stored energy from fossil fuels. Its flows involve natural phenomenon such as sunlight, wind, tides, plant growth, and geothermal
