Short Essay On Renewable Energy

Renewable energy

Introduction

Renewable energy is energy production from sources that are naturally available in the environment and considered to be more sustainable to development and energy use. This implies that these sources of energy are inexhaustible without the risk of over exploitation and endangering of future populations. They also have minimal carbon dioxide (Co2) and Green Houses Gases (GHG’s) emissions, and therefore have less devastating effects on the environment and continual climate change. A discussion on the various sources of renewable energies available and ways in which improvement and advancement in technology can lead to increased efficiency and reduced pollution will ensue. Energy use though not reflective of a nation’s economic growth, is vitally important for the operations of major economical means of production. As man is dependant on the growth of his economy for necessities like food, he is also dependent on a favorable climate to guarantee his survival. Renewable energy is thus the cutting edge to ensuring that there is a sustainable development that is considerate to both the economy and environment.

Sources of Renewable energy

Renewable energy has been in use since the early days of man. The use of biomass to fuel fires has been practiced since early use of fire energy. Wind energy was

Its main type of energy is hydroelectricity that is harnessed from dams constructed across rivers. Large hydropower dams are common globally with the largest dams found in China and South America. The Three Gorges dam in China produces around 17% of the total domestic electricity use (Quaschning, 14). The use of hydroelectric power can be exploited even in small rivers for smaller domestic power uses mainly in rural areas. Another form of un-exploited sources of hydropower is wave power or tidal power that converts tide and waves energy found in oceans and seas into power
