![]() ![]() Limited availability of sites has remained a major constraint in the development of tidal power projects.īut recent innovations in design and turbine technology for tidal power are expected to offer the potential to increase the installed capacity of tidal plants. Site availability constraints Tidal energy is generated by converting energy from the force tides into power (Credit: Shutterstock/Francois BOIZOT) Pros and cons of tidal power: Disadvantages 1. Given the longer life span of tidal power plants compared to those that depend on fossil fuels, they are considered as cost-effective.Īlso, tidal plants can be effective at low tides speeds and produce power to bring down the overall costs. The construction of the projects can also be carried out with correct dimensions based on the formation of high and low tides in certain cycles.Īssessment of these factors can help to easily determine the size and capacity of a tidal plant in a particular area. Tidal power installations also occupy less space compared to other modes of power generation.Īs it is easy to know the occurrence of tidal currents, the scope of a tidal energy project can be measured with consistent acuity and accuracy. Tidal power projects do not need much space compared to solar farms, which require a large area of land for installation of modules. Taking this into account, tidal energy generation may last for thousands of years as long as its tides remain.Īs tidal power generation emits no harmful gases into the atmosphere, it is an environmentally friendly energy source. Renewable The world’s first large-scale tidal power plant became operational in 1966 (Credit: Shutterstock/Arild Lilleboe)Īs it is derived from tidal waves, which result from the gravitational pulls from the sun and the moon and the earth’s rotation around its axis, tidal power is classified as a renewable energy source.Ĭompared to limitations in power generation from finite fossil fuel reserves, tidal energy does not have any such constraints. ![]() Pros and cons of tidal power: Advantages 1. Here, NS Energy takes a closer look at the pros and cons of tidal power. Today’s increased focus on the proliferation of renewable energy is expected to change that, however, as companies and countries alike look for new sources of clean power to exploit. Tidal energy is generated by converting energy from the force tides into power, and its production is more predictable compared to other generation types such as wind energy and solar power.īut, despite the fact the world’s first large-scale tidal power plant became operational in 1966, the energy source is yet to reach the heights many had anticipated. Tidal energy production is more predictable compared to other generation types - but the power source is yet to reach the heights many had previously anticipatedĪlthough the world’s first large-scale plant of its type became operational in 1966, tidal power is still not widely used (Credit: Shutterstock/Breedfoto)Īlthough the development of tidal power is at a nascent stage, it is forecast to play a significant role in the world’s future energy mix – but the technology has various pros and cons.
