Description: Onshore wind energy refers to energy generated by wind turbines located on land. This type of renewable energy harnesses the power of the wind to convert it into electricity, using wind turbines that transform the kinetic energy of the wind into mechanical energy and then into electrical energy. Onshore wind turbines are generally more cost-effective to install and maintain compared to their offshore counterparts, making them a popular option in many regions around the world. Additionally, their development has been driven by the increasing need for sustainable and clean energy sources in the context of climate change and the search for alternatives to fossil fuels. Onshore wind energy not only helps reduce greenhouse gas emissions but can also create jobs and promote economic development in rural areas. As technology advances, turbines become more efficient and capable of generating more energy, increasing their viability as a primary energy source in the global energy mix.
History: Wind energy has its roots in antiquity, with the use of sails on boats and windmills for grinding grain. However, the development of modern wind energy began in the 19th century when the first wind turbines were built to generate electricity. In 1887, Scottish engineer James Blyth built a wind turbine to power his home in Scotland. Throughout the 20th century, technology advanced, and in the 1970s, the oil crisis spurred renewed interest in renewable energies, including wind energy. Since then, onshore wind energy has grown exponentially, becoming one of the most widely used renewable energy sources in the world.
Uses: Onshore wind energy is primarily used for electricity generation. Wind turbines are installed in wind farms, which can range in size from a few turbines to hundreds of them. The electricity generated can be used to supply power to electrical grids, industries, homes, and communities. Additionally, onshore wind energy can also be integrated into hybrid systems alongside other renewable energy sources, such as solar, to enhance the stability and efficiency of energy supply.
Examples: A notable example of onshore wind energy is the Gansu Wind Farm in China, which is one of the largest in the world, with an installed capacity of over 7,965 MW. Another example is the Alta Wind Energy Center in California, USA, which has been operational since 1980 and has significantly contributed to renewable energy generation in the region. In Europe, the Hornsea One Wind Farm in the UK is an example of how onshore wind energy has been integrated into the country’s energy mix.
