It has always been a challenge to people the control of pollution non-renewable resources bring. Also, scientists are trying their best to find out the probable ways to reduce the global warming caused by the non-renewable resources usage.
Renewable energy is the naturally replenished energy that comes from the environment. It includes energy coming from the sun as well as from the wind. One of the most recognized models of the renewable energy source is called Wind Turbines. This machine gets energy from the wind because of its rotating part. It can be segregated into two – machine that makes use of the energy directly and machine that converts energy to electricity. The former is called Windmill while the later is a Wind Generator. Aside from wind source, solar cells are also an efficient supply that became accessible to homeowners as Scientists consider that the technology will be competitive (Berg, n.d.). It is known that solar energy can be obtained through radiation. Photovoltaics and heat engines are just some techniques used to extract energy from the sun. In a photovoltaics method, electricity is produced by converting the sun’s radiation with the use of semiconductors. Thus, letting the electricity flow and be obtained. Aside from the mentioned renewable energy sources, an alcohol can also be a form of energy source. Ethanol can be naturally produced from sunlight. The production is possible through the process called Photosynthesis that brings about feedstock. Last but not the least, there is Hydropower. Water energy can also be obtained and be gathered through hydroelectric dams.
There are now available alternative resources of energy. However, the question that still remains is on the reliability of these sources. Indeed, oil fuels until now have not met its rival. It still has the greatest impact to people and their welfare. Unlike coal and gas, storage is a challenge in managing

Reducing the use of fossil fuels is an important factor as it helps in diminishing the adverse economic impacts resulting from climate change. This is the main reason why individuals are focusing on the utilization of greener energies such as solar, wind, hydropower among others (Pullen, 2009).
Firstly, the author mentions wind energy which uses which uses windmills to turn wind into energy. Secondly, there is solar power which uses photovoltaic cells to focus the rays of the sun into a narrow shaft of light which turns an engine and produces electricity.
Energy continues being a key challenge facing many countries. The concern for the countries is the sustainability and the effects of the current sources of energy on the environment. The renewable energy is from the natural processes which are replenished constantly (Solway, 2010).
There are however very many implications of this upward trend in the growth of the world’s population as far as their energy requirements and consumptions are concerned. Proper planning strategies therefore have to be put in place for the world governments to ensure that the energy requirements and provisions remain the same.
While there are so many benefits of renewable energy, its production remains to be in small scale and a secondary energy source unlike energy from fossil fuels. The main challenge that faces the implementation of full exploitation of energy from the renewable sources is that the sources are believed to be varying with seasons.
Renewable Energy VS Fossil Fuel. In recent times, there have been worries in the energy sector over the possibility of clean energy instead of using the type of conventional fuel that pollutes the environment and has been affecting it negatively, one of the notable negative impact of fossil fuels is increase in the global warming.
On the other hand, the non-renewable energy sources such as fossil fuel continue to be depleted, which will translate in to higher energy costs in future. Production of energy, for example the oil refineries amongst
Energy security is defined by the international energy agency as the uninterrupted availability of energy sources at a reasonable price. There are various aspects that are associated with energy security. Short-term energy security focuses on the ability of the system of energy to respond promptly to immediate changes in the supply-demand balance.
