abdominal effusion. Refers to a condition in which fluid collects around the vital organs located inside the abdomen. This is normally the side effect of a more serious condition, like liver disease or heart disease.

Quick Facts. 1  Hydropower is a renewable, efficient, and reliable source of energy that does not directly emit greenhouse gases or other air pollutants, and that can be scheduled to produce power as needed, depending on water availability.ydropower, or hydroelectricity, is electricity generated by the force of moving water in the penstock [8] of a hydropower unit. Turbines are used to capture the kinetic energy of water by converting it to electricity as the falling water spins the turbine.
Hydroelectric energy is a very important energy source, both nationally and worldwide. About 19% of the world's total electricity production comes from hydroelectric energy and about 7% of the power in the U.S. When we look at hydroelectric energy for the U.S. in terms of renewable energy sources (so comparing this to things like solar power, wind power, geothermal energy and biofuels), it makes up 96% of renewable energy electricity production.
