Global Wind Day is held every year on June 15th. According to the day’s official website, “It is a day for discovering wind energy, its power and the possibilities it holds to reshape our energy systems, decarbonise our economies and boost jobs and growth.” In order to fully appreciate wind energy and how it has altered the way we address renewable energy, we must first understand wind power.
What Is Wind Power?
Wind power, or wind energy, is the process that uses wind to generate mechanical power or electricity. Through use of wind turbines, the kinetic energy in the wind is converted into mechanical power. When the blades of the wind turbine are turned by the naturally-occuring wind, they spin around a rotor, which in turn spins a generator, creating and storing electricity. Though many areas have strong winds, experts suggest the best location for these wind-harnessing turbines is far away from densely populated areas, preferably near the shoreline by the coast.
Humans have been harnessing wind flow, or motion energy, for years to sail a boat or fly a kite. The wind turbines take this a step further, by either using the mechanical power to grind grains or pump water, or convert the mechanical power into electricity. Through use of aerodynamic force from the wind, the spinning turbines are able to rotate the internal generator, which then creates electricity.
Is Wind Energy Good For The Environment?
Wind is a renewable energy source, similar to solar power and hydropower, which means there is minimal waste involved. The wind turbines used to gather the wind’s energy do not release emissions that can pollute the air or water, and do not need water for cooling like nuclear power plants. However, there have been some, although minimal, incidents where wind turbines have caught fire or have leaked lubricating fluids. Additionally, creating the mechanical and metal parts for the turbines has an impact on the environment, with fossil fuels sometimes being used to produce these materials.
Overall, renewable energy has a much larger, more positive impact on our Earth and environment when compared to fossil fuels. Fossil fuels are one of the largest source of U.S. carbon dioxide emissions, which is depleting our ozone layer and contributing to global climate change. Although renewable energy sources aren’t completely clean and without fault, they have a much smaller carbon footprint, all while creating new job opportunities for local communities.
How Can I Celebrate Global Wind Day?
The best part of Wind Day, like many other holidays focused on our Earth, is that you can celebrate in any way you wish! Just knowing about the holiday, and taking the time to appreciate this powerful energy source that is around us all day every day, can be enough to celebrate this day. You can also take your family to visit a nearby wind farm to learn about the turbines and see them up close. Or see if your local community is planning on hosting a wind parade or workshops! Better yet, explore the power of wind energy at your own home by letting it sing through your wind chimes.
Whatever you choose to do, take a moment today to appreciate our Earth and consider how you can incorporate renewable energy into your daily life.Whizzco
