Although wave energy technology can fuel some percent of the planet’s energy, the efficiency of the methods to get wave energy is still not high. Hence people still keep developing the methods that achieve high-efficiency energy conversion. Not only that, but the devices of generating wave energy must be cheap enough. However, some of devices are really expensive and people have to cost millions of dollars to test an idea of power generation product. The equipment is also easily damaged by harsh waves and strong storms. Hence they need lots of investments to refine and test designs. For example, for Carnegie’s pilot project, they begin with more than $30 million from investors and the Australian government, including $13.1 million from AREA (Australian Renewable Energy Agency) and $7.3 million from the Low Emissions Energy Development Program for Western Australia.³
