Blue Energy. Depending upon whom you ask, you will get a range of answers if you ask “What is Blue Energy?” The answers will range from the very specific to the quite broad. A specific response to the question is that Blue Energy is what results from the interaction at the point fresh water rivers roll into the salty ocean. Electricity can be harvested in this situation but the science is still in its infancy. Blue Energy can also be the range of ways in which the ocean can be a source of green renewable energy, including the one just mentioned where fresh and salt water mix, plus wave energy, tidal power, power from ocean currents, and a few others. We will add here power from seaweed, although that could be re-assigned to a category dealing with power obtained from agricultural products.
