How Does Wind Energy Occur?
Wind energy starts with the powerful warmth of the sun. When the sun radiates heat in a specific land location, air particles around that area absorbs the heat being radiated. The reason for this is because heat flows from a hot object to a cold object and not the other way around. Once a certain temperature of heat is reached it makes the activity of air particles move faster.
Wind Energy In Action
This fast movement enables hot air particles to go up, since hot air particles have higher levels of temperature and faster movement; it pushes its pressure to the way up leaving the lighter and slower cold air down. The exchange in position of hot air molecules and cold air molecules and the transfer of heat from hot to cold is what we humans feel as wind currents. This is also the reason why majority of wind currents are cold while there are some that are warm and hot.
Wind is similar to particles of water in the sense that its molecules are freely moving in contrast to water molecules that are connected loosely with one another. Wind energy is invisible, yet we can feel the breeze of air similar to how we detect the presence of water.
As we feel the breeze of wind, air molecules are colliding on our bodies in which their motion is what is referred as kinetic energy. The kinetic energy being given by the wind could then be captured by wind energy turbines similar to hydroelectric dams that capture energy from the motion of the water. In the case of wind electricity, the motion of the wind is being captured by windmill turbines to convert it to electricity.
Wind Energy and Turbine Blades
As the turbine blades capture wind currents it then spins the blades that lead to the motor of the wind power generator. The generator would then convert that motion into electricity that could be commercially used to power our appliances in our homes. In one perspective wind energy or wind power is simply the transfer of one form of energy to the other.
The advantage of wind is that it is always replenished even if we do nothing at all. Wind power is a good source of electricity especially for those living in windy areas since they can save the environment by burning less fluid and save a little money of their own from the discounts that they can attain in their monthly electric bills.
The problem why wind power is not being used today is because wind is intermittent. Wind turbine generators heavily rely on wind power to generate electricity from its magnetic coil. If no wind is produced then no electricity would also be produced. This is the reason why individuals who are living in windy areas have the privilege to use wind power as their source of energy. Another problem why wind energy is not being used widely is that it accumulates space. Large amounts of electricity could only be produced through wind turbines that can generate enough power to create electricity. This may be great in some home owners; however, majority of city dwellers who lives in a condominium or in an apartment may not be able to enjoy the electricity bought by wind power.
Wind Energy for Home Use
Home owners as well as those individuals living in windy areas that have a vacant lot are highly recommended to patronize equipment that use wind energy in order to reap its fruitful advantages. By utilizing wind power as your source of electricity not only did you save the environment but you would save some money for yourself.
