Wind turbines capture the kinetic energy of wind and convert it to electrical energy. This electricity is then sent on the National Grid for powering homes and businesses alike.

Wind energy can be unpredictable and unreliable, so it should be combined with more stable sources such as hydropower for increased control over electricity production.


Wind turbines are large machines that use the force of wind to spin their blades and generate energy. While this major investment must be carefully considered and planned, wind energy could potentially provide an abundant source of renewable energy sources.

The cost of a wind turbine depends on its size and where it will be placed. Roof-mounted models tend to be the most affordable option; however, these aren’t as efficient or economical as free-standing machines.

Costlier wind turbines for residential projects that need regular upkeep (between PS100-PS200), while smaller wind turbines that provide enough power for a small household or business can be had for as little as PS7,000.

Wind turbines come in two primary varieties: vertical axis and horizontal axis. Vertical axis turbines feature blades or rotors spinning up and down like a clock face, making the gearbox and generator easier to access for maintenance; however, this design may not be ideal for those looking to use the electricity produced for running businesses or homes.

Wind turbine’s capacity to generate electricity depends on the quality of the local weather. An average annual wind speed is essential for wind turbines to run at optimal power output levels.

Wind speed in your area can easily be determined with a wind map, available online from the National Oceanic and Atmospheric Administration or at your nearest airport.

Another essential consideration is the cost of transmission lines to bring electricity directly to your home or business. Unlike hydroelectric dams, these require a substantial upfront investment and are not included in the price of producing energy they produce.

Costs associated with wind turbines range from several thousand dollars for a small unit to over one million dollars for an offshore one, but aren’t included in the direct cost of electricity as these costs are spread among many customers.

Environmental Impact

Wind energy is a renewable resource of electricity that can help combat climate change. However, its environmental effects must also be taken into account when deciding whether or not to use it as an energy source.

Water consumption, air pollution and land use impacts must all be taken into account when selecting a renewable energy source. Although both issues pose significant environmental challenges, they can be mitigated through thoughtful planning, implementation and upkeep.

Wind turbine components are made with materials that have environmental consequences. Emissions such as sulfur dioxide and nitrogen oxides contribute to global warming, with acidification of soil and loss of vegetation. Utilizing renewable resources in production helps minimize these effects on the environment while decreasing fossil fuel usage for production.

Noise from wind turbines is another environmental concern that can be reduced through better siting and operational practices. By adjusting rotor speed and pitch angle, wind turbines can be set to operate at levels which meet local regulations while being quiet enough for nearby residents to enjoy peace and quiet.

Bird and bat deaths due to collisions with wind turbine blades are a grave concern. Studies have demonstrated that keeping wind turbines motionless during low wind periods can significantly reduce bird and bat mortality rates.

Wildlife-friendly designs are being implemented to avoid drawing birds and bats into the area around wind turbines. This can be accomplished through sensors that detect wildlife activity, sound and vibration deterrents to prevent birds from contact or death of turbines, as well as creating wind farms on brownfields or other industrial sites with minimal environmental damage during construction or operations.

Wind energy is one of the most sustainable forms of power production and can play a pivotal role in reaching global goals to reduce carbon emissions. This has been made possible thanks to advances in technology that have transformed basic wind turbine designs into highly efficient energy harvesters that require minimal upkeep, generate high-quality electricity, and are quiet when operating.


Wind turbines harness the energy of wind flow to drive generators that create electricity. They may also be utilized for grinding grain or pumping water.

Wind turbine noise levels can vary due to various factors, such as distance from populated areas, operating conditions and maintenance of the machine. But most importantly, mechanical noise from components within the turbine itself is responsible for creating this noise.

Modern wind turbines tend to be relatively silent, so they usually don’t disturb people too much. However, if the turbine is situated close to a home or other structure, neighbors may find the noise an annoyance.

Furthermore, noise from wind turbines can have adverse effects on wildlife. Birds and bats that fly through the air could be injured or killed by their encounter with the sharp blades of a turbine’s turbine.

Modern wind turbines tend to be remarkably quiet, but some older models can produce louder sound than their more modern counterparts due to being not as noise insulated and having a higher-pitched gearbox and generator that produces louder sounds.

One of the best ways to reduce noise is by placing wind turbines in rural areas with low population density and no homes or businesses nearby. This ensures that noise levels generated by a turbine will likely be well below those required by law.

Another way to reduce the noise produced by a wind turbine is to yaw the turbine. By doing so, the angle of its rotor blades can change to match the direction of the wind, decreasing noise production but making maintenance harder.

Another way to reduce wind turbine noise is by installing a generator beneath the turbine nacelle. This makes the rotor blades quieter while in operation and may increase efficiency as well.

Aside from the factors mentioned previously, other elements that can influence wind turbine noise include the type of tower, blades and generator. A twisted Savonius type turbine generates more noise than a vertical axis wind turbine and is harder to repair or more inefficient at producing energy than its vertical-axis counterpart.


Wind turbines are intricate machines that need regular upkeep to stay operational. Wind farm operators and electric power providers depend on maintenance technicians to keep the turbines in optimal condition at all times, performing tasks such as lubricating moving parts, inspecting system connections, and quickly fixing malfunctions before they become major issues.

Maintenance costs for wind turbines can vary based on the size and specific needs of each site. An offshore facility might need to arrange for repair vessels to come out, while onshore facilities might have maintenance technicians climb ladders with heavy equipment and spare parts while working together with cranes to reach damaged parts of the turbine.

Maintenance is an integral part of managing any mechanical asset, and avoiding unexpected downtime can save your company a substantial amount of money. Whether you work in oil and gas or construction, if a part is down for too long it could mean missing out on valuable revenue opportunities.

For instance, if your gearbox isn’t properly lubricated, it could cause an outage of up to 14 days and be costly. By keeping the gearbox well lubricated, you can reduce unexpected repairs and extend the life of the turbine.

Many wind farms utilize preventative and predictive maintenance programs to guarantee their turbines remain in top condition. These systems utilize sensors placed on key components that send valuable data back to the maintenance team, alerting them if lubrication levels are too low, vibration is too high, or temperatures are too hot. With this data they can plan for any necessary maintenance needs ahead of time and minimize unscheduled repairs.

Maintenance programs typically include physical inspections of turbine blades and other key parts to detect any signs of damage. Technicians also conduct acoustic checks to listen for suspicious noises or other issues.

Wind turbines, unlike fossil and nuclear power plants, must often be serviced during periods of lower electricity demand due to less favorable winds. This translates into higher maintenance costs during these times which can have a major effect on the profitability of a wind farm.
