What Is Wind Power? & Alternative Ways of Producing Wind Power

The total amount of economically extractable wind power is more significant than the present human consumption of all sources of electricity. Moreover, the strength of wind varies with the location, and average wind speed alone does not necessarily mean the amount of energy a wind turbine could produce. This is why there is a need to calculate the specific amount of wind energy for the location where a wind turbine would be installed. 

What Is Wind Power?

Wind power or wind energy is the process of harnessing the wind to generate mechanical power or electricity. Wind turbines convert wind kinetic energy into mechanical power. This mechanical power can be used for specific tasks (such as grain grinding or water pumping) or converted into electricity by a generator.

Wind power, also known as wind energy, uses wind turbines to generate electricity. Wind energy is a popular, sustainable, renewable energy source with a much lower environmental impact than burning fossil fuels.

Variability of Wind Power

While there is much debate about the effectiveness of wind energy as a renewable source of electricity, the truth is that it does work. The primary benefit of wind power is its affordability and environmental sustainability. The problem of wind energy variability has caused many policymakers and researchers to examine alternative ways of producing power. Fortunately, there are solutions. Read on to find out how these alternative energy sources can be more efficient. We’ll also look at how wind energy differs from other renewable sources.

Variability in wind power production is a serious problem. Wind turbines can be highly variable, so integrating multiple wind plants is difficult. The variability in wind power is particularly problematic because it can cause power grid instability. Moreover, it can push up the balancing costs of electricity markets. As a result, it’s essential to curtail wind power variability. One way to limit wind power variability is to aggregate multiple wind-generating sites geographically. However, there’s a lack of comprehensive global evaluations of this option.

Cost of Wind Turbines

While the initial investment in wind turbines can be low, the maintenance and operating costs are an ongoing expense. A single wind turbine can cost between $42,000 and $48,000 per year, depending on the size and type. This amount includes insurance, legal fees, and administrative costs. As wind turbines age, maintenance costs also rise. The average age of a wind turbine is six years, and engineers are constantly improving their technology to reduce costs.

Residential wind turbines range in price from a few hundred dollars to over $100,000. They are typically small and are installed on roof-tops or poles. A ten-kilowatt (kW) system costs around $50,000-$80,000, which is enough to power a standard-sized home. A 15-kW system can cost upwards of $100,000, producing more than 36,000 kW per year.

The Energy Produced by a Wind Turbine

A wind turbine is a type of turbine that converts the wind’s mechanical energy into electricity. The blades on a wind turbine rotate in response to a wind gust, a breeze of three to five meters per second. This spinning motion turns the shaft inside the nacelle, a box-like structure at the top of the turbine. The nacelle contains a generator that converts the energy to electrical energy. The electricity produced goes through a transformer, which steps up the voltage of the power to be distributed on the National Grid or for local use.

The energy produced by wind turbines is measured as an annual average, but this number masks the erratic nature of the output. If the wind slows down by half, the production of a turbine will decrease dramatically. At the same time, the average production rate is only observed forty percent of the time. Because wind turbines depend on the wind, balancing the energy produced by these devices is often complex.

Offshore Wind Energy

Offshore wind energy refers to electricity production by wind turbines placed in lakes and oceans. This energy source is increasingly becoming an attractive option for developers due to the lack of land on land. Moreover, a large portion of the world’s population lives along coasts. Using wind energy in the oceans would allow developers to harness a renewable resource near major population centers. Many countries have focused on this energy resource in the last decade. In fact, according to the Renewables 2019 Global Status Report, the potential for offshore wind energy is growing steadily.

The Coastal Act, which governs coastal development, requires the Coastal Commission to review federal and state activities outside the coastal zone. In addition, the Ocean Protection Council advises the legislature and governor on policy matters and supports evaluating offshore wind’s effects. The organization’s strategic plan outlines its commitment to supporting sustainable commercial offshore wind development. In California, the Coastal Commission has already endorsed this goal. Its mission is to protect and preserve the environment.
