Cost of electricity ……
The cost of electricity (typically cents/kWh, Euro/kWh, Euro or $/MWh) generated by different sources is a calculation of the cost of generating electricity at the point of connection to a load or electricity grid. It includes the initial capital, discount rate, as well as the costs of continuous operation, fuel, and maintenance.
Problems with non conventional except tidal source
Solar
continuos generation not possible.
high cost.
not possible in rainy season.
Wind
according to wind speed only
not possible at all places
high cost of wind turbine.
Tidal power
Continuous power generation
Possible at all sea shores
No pollution
Eco friendly
Power conversion easy
Advantages of tidal power
potential for future electricity generation.
Tides are more predictable than wind energy and solar power.
many recent technological developments and improvements, both in design (e.g. dynamic tidal power, tidal lagoons) and turbine technology (e.g. new axial turbines, cross flow turbines), indicate that the total availability of tidal power may be much higher.
Recent power generation trend with tidal power
Tidal power has potential for future electricity generation.
Tides are more predictable than wind energy and solar power.
Among sources of renewable energy, tidal power has traditionally suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities, thus constricting its total availability.
Some Disadvantages of tidal power….
Tidal power has traditionally suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities.
Thus constricting its total availability.
Economic and environmental costs may be brought down to competitive levels.
