Everyone uses energy. To keep ourselves alive, we need a certain amount of energy to provide for the human need for food and to do work. Energy, especially electricity, is essential to provide water, food, health care, education, employment and communication. But where does this energy actually come from? And how can we improve it?
A New Way Of Energy Supply
The most substantial amount of energy comes from fossil and nuclear fuels, which currently face serious difficulties, such as security of supply, economic affordability, environmental sustainability and disaster risks. In order to cope with these problems, we are looking for a solution to increase renewable energy technologies. For example, in recent decades there has been rapid growth and spread of renewable power plants. Among them, wind generators are the most widespread type of renewable energy. This trend continues and is a positive development. However, this could be different in the near future. There could be a saturation of windy areas inland. For this reason, the current research programmes are aimed at improving the power capacity per unit of land. This translates worldwide into the development of several wind turbines with improved nominal capacity.
A New Way Of Energy Supply. What Are We Doing Worldwide?
Worldwide, people are investigating what could be improved. Since the beginning of 2000, researchers have been looking at offshore installations. At these places located far enough from the coast, wind energy sources are generally larger those on land. Wind energy is stronger and more regular. This allows for more constant use and more accurate production planning. In this context, an entirely new renewable energy sector has emerged in the scientific community: AWE.

What Is AWE?
Awe means Airborne Wind Energy. It is a new way of transforming wind energy. Airborne Wind Energy focuses on capturing wind energy at considerable heights, at least 500 meters! Machines that 'capture' this type of power is referred to as Airborne Wind Energy Systems (AWES). The wind at this height is stronger, and the systems provide higher efficiency than the conventional wind turbines.

Moreover, they are cheaper, less visible and can be used in places that are difficult to reach. This new way of transforming wind energy can reach layers of wind at enormous heights, utilising strapped wings or aircraft and drones. These are not accessible to traditional wind turbines. Research into these Airborne Wind Energy Systems started in the 1970s, but development has accelerated in the last decade. This new software of wind transformation was developed by researchers from the Carlos III University of Madrid.
A New Way Of Energy Supply: The Dutch Startup Kitepower
The focus on wind energy at high altitude is increasing. Researchers are exploring what is possible. The Dutch start-up Kitepower, founded by a research group at TU Delft, is developing an AWES based on kites to generate energy at high altitude. A 100kw system is now being designed that, for example, can replace diesel generators in isolated areas. Producing, transporting and installing wind turbines on land and at sea costs a lot more time and money compared to airborne wind energy solutions. Wind at an altitude of 200-450 meters is stronger and more constant than the wind that captures windmills. Kitepower is developing a power generating kite system for this source of renewable wind energy in the air. These kites are quiet, simple to install and easy to use. Kitepower uses less material than ground-based turbines, and it takes less than an hour to install them. Their kites float through a large part of the air, resulting in very powerful wind speeds.

Most people rely on diesel generators, with a high dependency on expensive and logistically demanding diesel supplies. Kitepower offers a more durable, flexible and economical solution. With its logistical flexibility, Kitepower provides an excellent alternative when the conventional power supply is damaged. Kitepower focuses on the transformation of energy in the world. They want a world where renewable energy is accessible and affordable for everyone. Their development is still ongoing and needs some refinement. Hopefully, we will hear more about this in the near future.
