business and finance green solutionsWhat are the four types of renewable energy currently being utilized from the ocean?
The key renewable marine energies are:
- Wind energy.
- Wave energy.
- Tidal energy.
- Ocean current energy.
- Energy derived from temperature differences at various ocean depths (ocean thermal energy conversion – OTEC)
- Energy derived from the different salt content of freshwater and saltwater (osmotic power)
Then, is the ocean a renewable resource?
That's because life in the oceans is a renewable resource. Unlike oil or other mineral resources, which come in limited supplies, ocean life renews itself. In fact, 82 marine species are at risk of extinction in North America alone.
Keeping this in view, what are different methods to obtain energy from sea?
There are three basic types that allow us to use ocean for its energy. We can use the waves (wave energy, wave power), ocean tidal power (ocean high and low tides), and we can even use temperature differences in the water to create an energy (Ocean Thermal Energy Conversion, OTEC).
Renewable. The oceans represent a vast and largely untapped source of energy in the form of surface waves, fluid flow, salinity gradients, and thermal. Ocean current turbines in areas of strong marine currents; Ocean thermal energy converters in deep tropical waters.
