Question: Discuss above theMarket Efficiency. Answer: Introduction: Renewable energy has been a more sustainable option which has been opted for by different countries and their governing systems across the world. These fuels are cheaper in some cases since they make use of available natural resources and the initial set up required is the harvesting equipment for the energy to be collected and used. There are different forms of renewable energy with sun, wind and water energy being the most common form of energy used in electricity generation. These take advantage of common phenomena present in the environment and they are harnessed using specialized equipment. Solar energy is harnesses using solar panels where batteries on the panels are charged by the heat from the sun then the energy collected can be used in future for operating other electricity dependent machinery. Wind energy is also harnessed where wind turbines are placed in areas of high altitudes where wind strengths are high. The turbines are rotated by the force exerted by the wind after which kinetic energy is produced and it is transferred to generators and other equipment for stepping up and generation of power. Part One Wind is a renewable energy which does not cause pollution however coal when used as a source of energy causes pollution and degradation to the environment due to the smoke which is produced after its combustion.

Cheap since only turbines need to be set up Expensive due to mining, transportation and processes of generation of electricity. Part Two Wind power over time has become one of the most common and quick growing sources of energy globally especially since it is free of pollution and cheap to make. Coal is an expensive fuel especially due to the process undergone to harvest it, prepare it for use and also the effects it has on the environment. Wind power is clean since the turbines do not produce any form of emissions which when released into the air could harm plant life and humans. Coal needs to be burnt to be used in the process it releases harmful gases which when released into the environment degrade it. Wind energy is also beneficial since it can be harnessed from almost everywhere. The major requirement is for turbines to be set up and they can be setup in farms, on hills and even in urban areas. Coal requires to be done away from areas where activities such as farming and busy towns are located due to the amount of emissions which are released in its production. Part Three The federal government has plans that by 2030 wind energy will be sustainable and will be able to sustain over twenty percent of the country as compared to current statistics showing that it stands at on average two percent. The Production Tax Credit, a body implemented with purposes of wind power harnessing has been made permanent so as to increase funding for wind farms so that more renewable and cheaper energy is produced. Australias renewable energy from wind power generation stood at twenty three percent which was enough to power over seven hundred thousand homes. In the country, there are over fifty two wind farms servicing the whole country with them generating a staggering five thousand gigawattz of electricity annually (Hansen, 2015). Conclusion Wind energy therefore is a better alternative due to it having lesser pollution as compared to coal as well as it being cheaper. Governments should form an alliance with public investors for them to seek opportunities in renewable energy as compared to them investing in coal since it degrades the environment. Wind energy is also safer since plants and animals are not exposed to hazards which could lead to them developing breathing problems as well as them not causing pollution which could lead to acid rain. Acid rain would lead to water sources being polluted and the diluted chemicals would have hazardous effects on people. References Hansen, M. O. (2015).Aerodynamics of wind turbines. Routledge.
