Postings without closing dates are often positions that are difficult to fill or ones that come open frequently. An example of a position that is difficult to fill is a psychologist at a small-town state hospital. If the hospital left the job open for a month, it is unlikely to get a sufficient number of applicants.
The Disadvantages of Tidal Power Tidal power is growing rapidly in interest as countries look for ways to generate electricity without relying on fossil fuels. Tidal schemes have a number of advantages, including their lack of greenhouse gas emissions and 100% renewable nature.
Ways to use tidal power: Tides produce by ocean can be used in three different ways to get energy and generate electric power. First is its wave energy or kinetic energy that water gets due to movement of waves.This energy can power the turbine if waves rise to a chamber and force the air out from there.In this ways moving air can spin the turbine. Second is energy of tides that come into the shore.These tides can be trapped in a dam and electricity can be generated by operating dam as regular hydroelectric power plant. Third form is oceanâs thermal energy.econd is energy of tides that come into the shore.
