Micro wind turbines can generate clean electricity in diverse locations, from urban centers to rural areas, without access to centralized grids.
If you''re an educator, pique your students'' interest in clean energy by exploring micro wind turbine technologies. Encourage them to imagine ways to make it better—perhaps someday they will!
Bring micro wind turbine technology to the attention of a nonprofit organization or development agency that could help advance its application in appropriate circumstances.
Access to the clean and affordable energy micro wind turbines providesupports education, health care, agriculture, and small businesses.
Deploying this climate solution stimulates local economies and creates employment opportunities. The installation, operation, and maintenance of renewable energy systems require skilled labor, creating jobs and contributing to economic growth.
Shifting to clean and renewable energy sources reduces indoor and outdoor air pollution, which is a significant health concern in many developing countries. By replacing traditional fuels like wood and coal with cleaner alternativesimproves air quality, reducing respiratory illnesses and related health issues.
In developing countries, this solutionexpands access to modern and reliable energy services, enabling communities to meetbasic energy needssuch as lighting, cooking, heating, and powering essential services like health-care facilities and schools.
Micro wind turbines allow for the extension of clean, renewable electricity in areas without grid access. Increasing micro wind turbine electricity generation to nearly 18.68–24.22 terawatt-hours by 2050 can deliver 0.09–0.11 gigatons of greenhouse gas emissions reductions with net first costs of US$52.87–69.56 billion.
Micro wind turbines are often used to pump water, charge batteries, and provide electrification in rural locations. They give people a way to light their homes or cook their meals while avoiding emissions from dirty diesel generators or kerosene lamps. Experts estimate that a million or more micro wind turbines are currently in use around the world. The key factor for growing that number is cost.
In urban areas, micro wind turbines offer an opportunity to become less dependent on the electrical grid. They are more expensive than large turbines, especially if connected to the grid. However, they can be integrated into urban infrastructure, such as building-mounted micro turbines.
The micro wind turbine market has been concentrated mostly in the US, China, the UK, and Germany. increasing electrification of emerging economy countries offers inroads for further expansion.
Project Drawdown''s Micro Wind Turbines solution involves deploying electricity-generating onshore wind turbines with capacity of 100 kilowatts or less. This solution replaces conventional electricity-generating technologies such as coal, oil, and natural gas power plants.
We based the total addressable market for micro wind turbines on projected global electricity generation from 2020 to 2050. The total addressable market is different for the two adoptionscenarios because Scenario 2 projects extensive electrification of transportation, space heating, etc., dramatically increasing demand and therefore production of electricity worldwide. Current adoption (defined as the amount of functional demand supplied in 2018) estimated from installed capacity is 0.008 percent (2.2 terawatt-hours) of global electricity generation.
We calculated impacts of increased adoption of the Micro Wind Turbine solutionfrom 2020 to 2050 by comparing two growth scenarios with a reference scenario in which the market share was fixed at current levels.
We assumed an average installation cost of US$6,481 per kilowatt with a learning rate of 9.7 percent, reducing the cost to US$4,536 in 2030 and US$3,742 in 2050. We used an average capacity factor of 18 percent for the solution, compared with 57 percent for conventional technologies such as coal, natural gas, and oil power plants.
We used US$0.03 per kilowatt-hour for variable operation and maintenance costs and US$127.3 per kilowatt for fixed costs, compared with US$0.005 per kilowatt-hour and US$34.7 per kilowatt for conventional technologies.
To integrate the Micro Wind Turbine solution with other Project Drawdown solutions, we adjusted the total addressable markets to account for reduced demand resulting from the deployment of energy-efficiency-enhancing solutions (e.g., LED Lighting and High-Efficiency Heat Pumps), as well as increased electrification from other solutions such as Electric Cars and High-Speed Rail. We calculated grid emissions factors based on the annual mix of electricity-generating technologies over time. We determined emissions factors for each technology through a meta-analysis of multiple sources, including both direct and indirect emissions.
The net first cost to implement Scenario 1 was US$52.87 billion from 2020 to 2050, with net lifetime operational cost of US$19.40 billion. Avoided emissions total 0.09 gigatons of carbon dioxide equivalent.
Under Scenario 2, greenhouse gas emission reductions total 0.11 gigatons of carbon dioxide equivalent from 2020 to 2050. The net first cost was US$69.56 billion from 2020 to 2050, with a lifetime net operational cost of US$26.58 billion.
We based these estimates on a conservative capacity factor. Since wind power is proportional to the cube of the wind speed, higher wind speeds result in much higher power. Doubling the wind speed in this framework would result in an order of magnitude increase in the carbon savings.
Building-integrated micro wind turbines are increasingly being explored to generate clean energy. However, because they represent an emerging technology, uncertainty about how factors such as low wind speeds, high levels of turbulence, noise, visual impact, and animal strikes influence performance makes it hard to determine their true potential, and their impact may not be felt until midway through the 21st century.

Microgeneration is the small-scale production of heat or electric power from a "low carbon source," as an alternative or supplement to traditional centralized grid-connected power.
Microgeneration technologies include small-scale wind turbines, micro hydro, solar PV systems, microbial fuel cells, ground source heat pumps, and micro combined heat and power installations.[1] These technologies are often combined to form a hybrid power solution that can offer superior performance and lower cost than a system based on one generator.[2]
In the United States, Microgeneration had its roots in the 1973 oil crisis and the Yom Kippur War which prompted innovation.[3]
on June 20, 1979, 32 solar panels were installed at the White House.[4] The solar cells were dismantled 7 years later during the Reagan administration.[5]
The use of Solar water heating dates back before 1900[6] with "the first practical solar cell being developed by Bell Labs in 1954."[7] The "University of Delaware is credited with creating one of the first solar buildings, "Solar One," in 1973. The construction ran on a combination of solar thermal and solar photovoltaic power. The building didn''t use solar panels; instead, solar was integrated into the rooftop."[8]
