Get to Know More about Wind Energy
Did you know wind energy was a form of solar energy? Well, now you do! Wind is the motion of air that results from the sun’s unequal heating of Earth’s surface. In other words, wind energy and the breeze we feel is what becomes of air that travels from the hotter portions of Earth’s surface into the colder regions.
These currents of air are what people ‘harvest’ by the use of wind turbines to produce wind energy or wind power.
To put ‘harvesting’ wind into simpler terms, a wind turbine converts kinetic energy of the wind into mechanical energy. This mechanical energy is then converted to electrical power with the help of a generator. It is then ready for distribution as this electric energy produced from wind goes through transformers and into appliance or equipment circuits.
Mechanical energy produced by the wind turbine doesn’t always need to be converted to electrical energy. It can be immediately utilized in specific tasks such as water pumping in farms.
Wind energy is a pretty neat power source. But there are a number of things to consider about it. It has its advantages and challenges as well as considerations when putting up a wind farm. But with the right circumstances, a wind farm may be able to provide as much as 1000MW to 5000MW of power.
Advantages of Wind Energy
There is no problem in harvesting wind continuously. Unlike its fossil fuel counterparts that run out, wind will have pretty much the same supply of resource in the future as it does now.
Wind power farms are known to generate between 17 and 39 times as much power as they consume, compared to 16 times for nuclear plants and 11 times for coal plants.
Wind energy produces non-polluting electricity. Unlike conventional power plants, wind farms emit little or no air pollutants and greenhouse gases.
In 2014, wind power avoided over 608 million tonnes of CO2 emissions globally. The number of CO2 emissions avoided further increased in 2016 with 637 million tonnes of avoided emissions.
3. Lower lifetime expenses
Building a wind farm requires a huge initial investment mostly on its machinery and installation. But throughout its lifetime, it costs less than conventional power plants which still includes fuel and operating costs.
