Using the power of water, both the small hydro and marine sectors have significant global potential; however, these are distinctly different sources of energy, with different dynamics. On the one hand, small hydro (projects under 50MW), traditionally the lowest-profile of the world’s clean energy sectors, presents a relatively low-risk, low-cost investment thesis. As a result this sector is enjoying a recent renaissance as clean energy investors have become more risk averse. On the other hand, electricity from wave is estimated to cost seven times as much as coal-fired power, and electricity from tidal stream turbines five times as much. Continued investment in these sectors should help achieve economies of scale and bring down the cost of generation, but investors are cautious and many marine technology developers remain cash-strapped.
