Why tidal and wave energy not common as solar and wind?

The tide and wave energy is the best examples of renewable energy sources.
But today we can,t see much tidal and wave energy conversion systems like solar and wind.
This video will tells you why...
Wind and solar power have taken off in the past decade or two, as costs have come down rapidly and threats from climate change have made clear the need to transition away from fossil fuels. Meanwhile, numerous studies have concluded that wave power — and to a lesser extent, tidal power — could contribute massive amounts to the overall energy picture. But while the industry has made halting progress, experts agree that it remains decades behind other forms of renewables, with large amounts of money and research required for it to even begin to catch up.
Tidal energy is still in its infancy, but it has the potential to make a huge impact on the world. You can see how important it’s poised to become by how much it’s worth: valued at $487million in 2014, experts expect the tidal energy market to be worth $11.3billion by 2024.
