Thirdly, another benefit of renewable energy is a diversified energy mix (Pasolini 2012). It is an

important and necessary supplement for global energy security while fossil fuel sources are

more and more running out. In some circumstances, renewable energy can be more reliable

than other forms of electricity. For example, if the grid gets breakdowns, renewable energy

technologies such as generators powered by photovoltaics (PV) can supply electricity

automatically. Efficient storage media such as batteries and fuel cells are keys for a renewable-

powered grid. If battery storage is added to the system, it can supply electricity even after the

sun goes down or through several cloudy or stormy days (Pasolini 2012).

Finally, renewable energy not only is regarded as an unlimited resource but also plays an

important role to regional development. Renewable energy and energy efficiency can help

revitalize rural communities (Parker 2010). For example, wind turbines or solar panel systems

can provide energy and provide rural communities with new tax revenue. Farmers on windy

lands can lease space to wind developers, earning thousands of dollars for each turbine every

year.
