The power of the wind is harnessed to propel the blades of wind turbine attached to an electric generator to generate wind energy. Wind energy is an effective alternative source of energy in areas where the velocity of wind flow is high.
This is the energy developed from the wastes of various human and animal activities like the by-products and wastes from timber industry, agricultural yields, municipal solid waste etc. Out of the many alternative sources of energy this is the one which takes into account the utilization of waste material to develop energy thereby disposing them off in a profitable and effective way.
This is the energy tapped from the heat inside the earth. Hot rocks residing in the core of earth heat water which emits the surface of the earth with pressure and as steam. This pressurized steam can be used to run steam turbines to generate electricity
The surface of earth is 71.11% covered by water bodies especially oceans. The tides in water rise and fall due to the gravity of sun and moon. Since we know about how the position of moon changes we can predict the rise and fall of tides. This rise and fall of tides can be utilized by setting up small dams and passing water through the turbines to generate power.
WHY DO WE NEED TO LOOK FOR ALTERNATIVE ENERGY SOURCE?
We need to look for it because if we do not have alternative energy sources then when we lose electricity that are not powered by the earth then we can't do any thing if we do not have the earth's resources.
WHAT IS THE CHOSEN ALTERNATIVE ENERGY SOURCE FEASIBLE AND RELIABLE IN THE PHILIPPINES?
The most feasible and reliable alternative energy source is Biomass Energy because it only uses wasted plant and animal and human waste . This does not use any resource of the earth it only uses the spoiled resources and this is why I believe it is the most feasible and reliable alternative energy source .
