Why don''t we use tidal power more?
"That''s a clear incentive for using tidal power," he adds. Another benefit of tidal power is its relatively high power output. Because water is roughly 830 times denser than air, tidal or ocean currents can generate more energy per unit area than winds.
solar power
Solar radiation may be converted directly into electricity by solar cells (photovoltaic cells). In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.(See photovoltaic effect.)The power generated by a single …
