Rivers require water to be transported to their head-waters. To do this the sun provide copious energy to evaporate sea water and cause weather to bright the moisture to the mountains.
Vitamins don't provide energy - or in any case, they don't provide any significant amount of energy. Just like minerals, we need them in small amounts, but NOT for their energy content.

One way is using wave energy and another is tidal energy. however wave energy is pretty new and tidal energy works better in rivers :)
because rivers provide us with: * food * energy * recreation * transportation routes * and water for irrigation and for drinking
New Zealand's rivers and dams supply hyroelectric power, and its hot springs provide geothermal energy.
It provide the energy required for locomotion like the trains.
South Asia's rivers provide fresh water for farming, and means of transportation and trade.
they provide hydroelectric power.
Rivers provide water, is the first and foremost thing necessary for the survival of most living creatures. For man, rivers provide the following: * drinking water * washing water * water for stock animals * irrigation for crops * water used in building and manufacturing * in some cases, a form of energy (hydroelectricity) * a means of transporting goods and passengers
Well, fish need rivers, and so do the plants that live around it. Humans may also need it if it has dams in it that provide hydroelectric energy.

cholesterol do not provide energy to body because the energy that contains the it wastes ots of energy so it doesnt provide energy.
they can provide water, minerals, and food
appliances that provide heat energy
Carbohydrates do not provide good energy
