One of the challenges of tidal wave energy is: the start-up costs are expensive. the materials needed to couple the tidal energy to electricity are rare. the tides are very unpredictable. as global warming increases, the tides will diminish.

One of the challenges of tidal wave energy is the start-up costs are expensive. Because it needs materials that do not erode quickly and can withstand the pressure of the incoming waves. This is another form of a renewable source of energy.
