Abstract - The world is rapidly shifting towards the use of
green energy sources to avoid the evils of fossil fuels which are not only limited in quantity but also cause pollution and global warming. Hydroelectric power is mostly tapped, the use of wind and solar energy is expanding but still has to go a long way, and new sources of green energy are being explored. Atmospheric pressure can be an unlimited, always available source of green energy which has so far remained untapped. The present study explores how it can be used to generate power. Water flowing through vertical rainwater pipes under gravity is observed to develop additional force when a partial vacuum is generated at the top end of the pipe. This phenomenon may be used to generate green energy. Chart –1: Contribution of various sources of energy
Key Words: Green Energy, Renewable Energy, Sources of Energy, Atmospheric Pressure, Vacuum Turbine, Fluid Flow through Vertical Pipe, Rainwater Pipe.
The importance of renewable and green energy sources like wind and solar energy is now well understood and their use is increasing day by day. Still, it may take decades to replace the fossil fuels as the rate of growth of energy from these sources is very low.
1.INTRODUCTION The quest for new sources of green energy is going on the world over to replace the fossil fuels which are limited in quantity, cause air and water pollution and lead to global warming.
It can be seen from the above chart that hydro and other renewable sources of energy contribute to about 14% of the world’s energy consumption. The composition of various sources of renewable energy is shown in Chart -2 (data source: Rahman et al. [3]).
The use of green energy sources like solar and wind energy is increasing day by day, still we are depending on fossil fuels to meet more than 80% of our energy demand. Atmospheric pressure can be potentially a great source of green energy. It is a renewable, unlimited source which has so far remained untapped. In this paper an effort is made to emphasize the possibilities of utilizing this untapped source of energy which has the potential to change the world energy scenario completely.
2.WORLD ENERGY SCENARIO The world energy demand is increasing day by day. It has more than doubled in the last 50 years [1]. Chart -1 shows the contribution of various sources of energy in the world in 2023 as per the data published by the Energy Institute [2].
