INTRODUCTION

Graph shows renewable energy generation for each type

The theoretical annual energy potential of waves off the coasts of the US is estimated to be as much as 2.64 TWH, or the equivalent of about 64% of total U.S. utility-scale electricity generation in 2021

INTRODUCTION

  • Can we depend on renewable energy efficiency ?
  • Renewable energy generates average 50-45% from the overall energy in United Kingdom, Norway and Sweden, Also its considered as Green economy

PROBLEM STATEMENT

  • The system has Low efficiency due to low air speed.

15 of 34

SURVEY

  • Most of the previous researches were interested and discussed the turbine in order to enhance the efficiency.

16 of 34

GAP ANALYSIS

  • In our project we are going to make experiments at the casing (gate length and angle) in order to collect more data to enhance the efficiency.

17 of 34

AIM AND OBJECTIVE

  • The aim of the project is to enhance the efficiency of the OWC housing by choosing optimum parameter of the gate dimension.

CONCLUSION

  • Fossil fuels take hundreds of millions of years to form.
  • Fossil fuels, when burned cause harmful greenhouse gas emissions.
  • Renewables are lower cost, environmental friendly and healthy and generate three times more jobs than fossil fuels.

FUTURE WORK

  • Doing the same steps for larger scale in order to reach the best casing design to increase the efficiency of the system.
