New technologies based on the use of PGEW are very important from the ecological point of view.

Already the first phase of development of the devices (using the new refrigeration cycle) will improve the environment. Reducing the total amount of Freons will help to preserve the ozone layer. The total energy savings will reduce the amount of hydrocarbons burned in power plants. The peak power demand will fall on hot days (in hot climates), when the use of air conditioners is maximal. This will reduce emissions of oxides of carbon into the atmosphere.

The second phase of the project will provide an opportunity to receive a significant amount of electricity using low-potential heat (water, which is sun-warmed to a temperature of 50–70 °C). This will further reduce the number of burning hydrocarbons as well as reducing the amount of heat discharged to the environment. These circumstances will certainly have a beneficial effect on the level of global warming caused by human activity. Perhaps this will allow us to completely abandon the use of nuclear power plants.

The third stage of development of PGEW devices will come when and if their effectiveness achieves the next level. In this phase the plants will produce electricity using heat, obtaining temperatures of 20–25 °C (surrounding air, sea- and river-water). THIS WILL CREATE A NEW POWER GENERATION INDUSTRY.

This will open up the prospect of a sharp reduction in the use of hydrocarbons (oil, coal, and natural gas). This stage of new technologies will not only be beneficial for preserving the environment but will also radically change our lives.
