Wave power: It makes the most of the movement of the waves.It's an easily predictable natural phenomenon from which the movement of water can be transformed into electricity. Tidal power: as we have seen, it makes the most of the rise and fall of the tides produced by the gravitational attraction exerted by the sun and the moon on our planet.Technology like this would help us meet future demands without compromising the atmosphere or enhancing the greenhouse effect.Before going further into tidal power and its role in the energy transition, it's worth clarifying that our oceans can provide us with energy in many different ways: As human populations grow, power needs will continue to grow as well. It isn’t some dream that an environmentalist has had. Instead of harvesting fossil fuels or risking safety through the creation of nuclear energy, we could obtain all the power we need in the natural movement of the earth itself. Imagine a world where we can produce all of the power that we need from something that is completely safe and effective. With so much energy potential at stake, supporting the development of this technology should become a high priority. The World Energy Council estimates that 2 TW of energy can be harvested from the waves.Ġ.1% of all energy would cover the worlds energy consumption 5x over. Tidal and wave energy consumption creates no liquid or solid pollution once the power generating facility has been completed. Smaller ways will always equal higher costs.Ībout 60 billion watts of energy from tides can be used for electricity generation Equatorial waters have very little wave energy. Most of the world’s wave energy is centred around the poles. Tidal power can be used anywhere there is tide, mostly along the coasts. It gives us hope that there could be a brighter tomorrow, especially if we can create power plants in a cost-effective way. The good news is that this technology can still provide us with energy if we are forced to eliminate the amount of carbon that goes into our atmosphere. Transitioning away from fossil fuels has an inherent cost that some societies may not be able to pay at this moment. Even though this technology is ultimately more efficient, our societies are built on the current production models of fossil fuels. With the ability to build energy producing facilities in any place where the tides come in or out, there are abundant places in this world today that could be retrofitted for tidal energy. It would take 222 tons of coal to replace just 1.8 GW of tidal energy that is produced – and all of the pollution that goes with coal. The main problem is reliability and the costs of the plants. The number of moving parts in an wave power plant is low, about 25-35%. That the tides have caused our planet to lose 17% of its total rotational energy course of its existence.ħ0% of the planet is covered with oceans and the energy that is stored in them as waves. Seawater is 832 times more dense than air, making it a more efficient energy source from an overall perspective.Īn 8 knot current is the equivalent to a wind turbine receiving 380 kph wind speeds on a consistent basis. With the number of existing seawalls that have already been built, however, the Sihwa power station proves that we could potentially do more with what we already have. That doesn’t even account for the changes in erosion that would need to be potentially fixed and the alterations of tidal patterns that could affect local wildlife. The technology currently exist to create large power plants that can produce 100 times this amount of energy, but it will cost billions of pounds to create. The largest producing active tidal energy power plant right now can only produce enough power for about 45,000 homes. It’s the cost of tidal energy that makes it such a difficult proposition to include for most societies. Tidal energy is clean renewable green energy and does not use any fossil fuels, thus has zero CO2 emissions and zero impact to the environment. There is only one title power station in the United Kingdom - MeyGen - and it has a capacity of 6KW.Ī proposed 8000 MW tidal power plant and barrage system on the Severn Estuary in the UK has been estimated to cost £11.5 billion.Ī tidal fence in the Philippines will cost an estimated £2.3 billion to produce 2,200 MW. The largest MW capacity for a title power plant comes from Sihwa Lake Tidal Power Station, producing 254 KW. The first tidal power station was created in France in 1966.
