Wind power

Today, wind power is generated almost completely with wind turbines, generally grouped into wind farms and connected to the electrical grid. In 2022, wind supplied over 2,304 TWh of electricity, which was 7.8% of world electricity. [1]

6 FAQs about [Wind power generation payback]

How does energy payback work?

Oil and coal, however, consume more energy than they generate and supply to the grid and never amortise. Alternatively, energy payback may be measured by ‘number of times payback’ – meaning, the amount of energy paid back to society versus the energy needed in the lifetime of that turbine.

What is the energy balance of a wind power plant?

The energy balance of a wind power plant shows the relationship between the energy requirement over the whole life cycle of the power plant (i.e. to manufacture, operate, service and dispose) versus the energy generated by the wind power plant.

How is energy payback measured?

Alternatively, energy payback may be measured by ‘number of times payback’ – meaning, the amount of energy paid back to society versus the energy needed in the lifetime of that turbine. Over the life cycle of a V117-4.2 MW wind power plant, it will return 50 times more energy back to society than it consumed.

How much energy does a wind power plant return to society?

Over the life cycle of a V117-4.2 MW wind power plant, it will return 50 times more energy back to society than it consumed. That means that when 1 kWh is invested in a wind energy solution, you get 50 kWh in return. For coal, however, if you invest 1kWh you typically get below 0.4 kWh in return.

How does a life cycle assessment affect a wind turbine?

Introduction: Going a step further than quantifying environmental impacts, establishing the environmental and energy payback times of a wind turbine can significantly impact the planning of a wind farm. This study applies the Life Cycle Assessment methodology to a wind turbine and verifies its environmental and energy payback times.

How has the cost of a wind turbine changed over time?

The cost has decreased as wind turbine technology has improved. There are now longer and lighter wind turbine blades, improvements in turbine performance, and increased power generation efficiency. Also, wind project capital expenditure costs and maintenance costs have continued to decline.
