renewable energy
Renewable energy is essential both from environmental and economic perspectives. Release Energy's mission is accelerate the momentum to 100% renewable energy. Our vision is to contribute in a significant way to a rejuvenated earth where humans and nature thrive together.
innovation in wind energy
Wind Energy is the world’s fastest growing renewable energy source, a trend that is expected to continue.
An integral part of wind energy will come from small to medium wind systems (10 – 50kW turbines). To provide perspective on thislarge wind turbines have diameters of 40 to 90 metres and are rated between 500 kW and 2 MW.
The majority of these large, commercially available wind turbines are Horizontal Axis Wind Turbines (HAWTs). These have a long-established design history. However, horizontal axis wind turbines have significant limitations, including:
Accordingly we see these HAWT turbines installed at a significant height (above obstructions in the airflow), in open areas (ridgelines and hilltops) and away from dwellings and other buildings.
Conventional wind farms typically consist of increasingly large HAWT designs in ever more remote locations, both onshore and offshore. Such large designs have high installation and maintenance costs, together with negative impacts on energy transmission costs and losses and the environment. The solution is to deploy Vertical Axis Wind Turbines (VAWTs)
Until now Vertical Axis Wind Turbines used either aerodynamic lift or drag. The problem with lift based VAWTs is that theydo not have the ability to self-start. The problem with drag based VAWTs is that they have low efficiency.
Release Energy's technology partner and major shareholder, Swift TG Energy has designed a VAWT that overcomes the disadvantages of both these types of VAWTS – Swift turbine design paves the way for urban wind generation.

The majority of these large, commercially available wind turbines are Horizontal Axis Wind Turbines (HAWTs). These have a long-established design history. However, horizontal axis wind turbines have significant limitations, including:
- They need smooth, non-turbulent airflow
- They cannot cope with rapid changes in wind direction
- They are noisy due to speed of blade tips
