7 Wind Energy Pros and Cons
Dec 16th
Wind energy is an inexpensive source of electricity that is being adopted by many westernized countries. Wind farms can be placed in open water and generate enough power to run an entire city. Despite the huge support for this renewable energy source, wind energy pros and cons need to be assessed before jumping into the wind.
Wind Energy Pros
Electricity is produced with let off of harmful gases or polluting agents. No fossil fuels needed.
Wind energy is self renewing. There are no crops or preparations needed to create alternative power.
Extra energy can be pushed out via the existing power grid.
Wind Energy Cons
Turbines can be easily damaged by storms or electrical strikes. At times, damage is total meaning the unit has to be replaced.
Energy production is not constant. As blades slow, less energy is produced leading to potential brown outs.
Noise is created by wind turbine blades. Slower moving blades produce more noise than faster moving blades. Average noise from moving wind turbine blades is 60 decibels.
As is the case with any form of alternate energy, wind turbines provide a renewable source of electricity that is currently being used to power entire cities, but there are drawbacks. The money it takes to build a farm is not recovered, in some cases, for 25 years or more and in that time the turbines could be damaged or outdated. But, in a world of fossil fuels and pollution, the cost in dollars may well be worth the benefit in time the earth allows humans to thrive.
