Got "Shocked", but not by electricity just by hearing the amount of electricity that can be generated by tidal energy as the source but with a huge investment(that may give shock to most of the investors). Why "TIDAL"? you may ask. Tidal energy sounds more interesting when we think of why we need to invest a huge amount of money for tidal and why not for other renewable's. There exists a big explanation for it.
Tidal power generation has lot of disadvantages associated with it like High Initial Capital Investment, Limited Locations, It's Effect on Marine Life, Long Gestation Time, Difficulty in Transmission of Tidal Electricity, Weather Effects(storms and typhoons), etc. When considering advantages like No Fuel, Long Life, High Energy Density, High Load Factor attracts big investors(Siemens and Vatten fall) toward it and it's Predictable nature, Renewable, Non-Polluting and Carbon Negative gets the most of the governments attention towards it.
The Danish government spent £1.3 billion to establish onshore wind, which currently brings £2.7bn per year in revenue. A properly capitalized wave and tidal sector could create 43,500 direct jobs and generate a potential £4.2bn per year in revenue for the UK economy - a report says.
Renewable UK’s State of the Wave and Tidal Industry report, released at the conference, states that the UK is still leading the world with the largest installed wave and tidal generating base of 2.4 MW, a further 27 MW with planning consent, 77.5 MW of projects in planning, and 700 MW expected in the Pentland Firth area by 2020.
In total, Renewable UK forecasts 1-2 GW of wave and tidal energy installations in the UK by 2020. Then installing tidal power in India not only helps the unemployment problems out here but also can supply the uninterrupted power to the whole nation(in Tamil Nadu there is daily power cut for 3-5hrs and so on in other states may fade out) when we utilize the most of the tidal energy available here. Finally tidal power sounds so promising.
