Another distinct disadvantage is relying too much on weather conditions and geographic locations

to create energy (Sinclair 2011). Each types of renewable sources is just better suited to some places.

This means that you cannot use each of these renewable sources in all locations. For instance, when

using geo-thermal energy, you must be in a location that provides the environment for geo-thermal

energy to be produced. Likewise, we cannot generate hydro-electric power without having a fast-

flowing water source, such as a river or waterfall. In addition, the energy also brings some

inconvenient problems. Take solar energy water heater as an example, it is inefficient because in

summer ambient temperature are high and the use of hot water is not needed; however, in the

winter we could not have hot water due to low light of the sun.

In addition, Shah (2011) claimed that “despite the fact that most renewable energy sources are more

environmentally friendly they may still have a negative impact on the environment”. He stated that

hydroelectricity projects can cause a dramatic change in the development of wildlife and ecosystem

along the river and flood risks.
