On a daily basis energy is used for a variety of reasons such as electricity, hot water or even fueling our cars. This energy mostly comes from fossil fuels like oil, coal, and natural gas. These energy sources are non-renewable which means if they are all used up, there will be no more left in our lifetime. Due to the fact that fossil fuels ran out and are not environment friendly, there is need to switch to other energy sources, like renewable energy sources. These energy sources such as sunlight, wind, and water are constantly being replenished. Renewable energy sources can be used without the worry of them running out.
For example wind energy as it sounds, is energy source from the wind. Windmills have been in use by humans for many years to pump water from the ground. Today tall large wind turbines are used to generate electricity (Phebe, Samuel & Shashi, 2016). Often in many developing countries wind turbines are placed together in wind farms and either flat or high areas with strong winds. An advantage of wind energy is the fact that it does not produce any waste or pollutants as opposed to non-renewable energy sources earlier mentioned. Moreover, it takes up little ground space.

Technology is important when combined with traditional sources of renewable energy. For instance the introduction of hybrid power systems that provides cost-effective utilization of renewable energy (Samuel, Ҫağlan, Herath & Shashi, 2016). These systems also depend on the geographical locations due to the variability of wind sources. Additionally, when these improved hybrid wind systems are integrated with Lithium-Ion bank batteries that store energy generated for longer time. Unlike the traditional wind turbines that generated energy and immediately consumed while not retaining any for future use. With this technological improvements, electricity in developing nations all over the globe have guaranteed long term energy source to light house holds, power machines and consequently leading to faster rate of industrialization.
