According to the Wind Technologies Market Report, Wind Power does not make up most of the United States’ energy mix, although it has grown in recent years. According to the research, renewable energy now accounts for more than 8% of the country’s electrical supply—and is approaching 10% in a growing number of states—and has seen a stunning $25 billion invested in 16.8 gigawatts of capacity.
The massive report, which the US Department of Energy released, draws on various data sources, including government data from the Energy Information Administration, trade data from the US International Trade Commission, and hourly pricing data from multiple systems. According to the research, Wind Power operations in the United States have greatly improved. This metric can be calculated using the capacity factor, a ratio of the amount of energy a turbine produces to the amount it could have produced if it ran at total capacity all of the time.
The average capacity factor for newly developed wind generating facilities has now surpassed 40%. However, the most significant advances in this area can be seen in the United States’ “wind belt,” a region that runs from the Dakotas to Texas and receives a lot of wind. Longer blades allow the turbines to generate more electricity when spun around by the wind, which accounts for a substantial increase.
According to the research, no turbines in the United States had rotors larger than 115 meters in diameter in 2010. However, rotors of this size or larger were found in 91 percent of new turbines last year. This size is also expected to grow, according to the report. The towers on which these rotors are mounted are likewise rising taller, sometimes with the blade size increase.
