Renewable energy from the ocean and tides: A viable renewable energy resource in search of a suitable regulatory framework
Ocean energy technology involves a range of engineering technologies that are able to obtain energy from the ocean using a variety of conversion mechanisms. Over the past few years there has been significant progress towards the development of commercial scale operations of ocean energy, especially hydrokinetic energy (where the energy of ocean (or fluvial) currents and tides is captured by ...

2014 JRC Ocean Energy Status Report
Abstract Oceans and seas have the potential to play a significant role in providing clean energy. Different technologies are currently being developed to ensure a long term contribution of ocean energy to the future energy system. Among the different ocean energy technologies, tidal and wave conversion systems are expected to contribute the most to the European energy system in the short to ...

Research and development in ocean energy technologies
The volatile fuel prices for electricity generation, elevated concerns about global warming and energy security has prompted countries to look for alternative energy sources. One of the alternative energy sources is ocean energy. Currently, there is few ocean energy technologies that are commercially available to harness electrical energy from ocean despite the fact that ocean covers more than ...

Ocean exergy and energy conversion systems
Oceans store energy in the form of currents, waves, tides, heat and salinity that can help to alleviate worldwide demand for power and the global climate change threat. They also store a considerable amount of an isotope of hydrogen (deuterium) which takes part in the most promising fusion reactions. Exergy analysis can be applied to evaluate the work potential (extractable) of a resource. This ...

Earthy, solaris and atmospheric energy sources
Earth, sun and atmosphere are the ultimate energy resources. In addition to fossil fuels, earth radiates over 45 TW geothermal energy. Sun radiates about 89 PW energy to earth's surface. Lunar gravity supplies over 100 GW tidal ocean energy. Accessible energy from geothermal, solar, tides, waves and winds is far more than our current 17 TW energy demand, yet there are new avenues like tornadoes ...

Oceans of Energy
Technologies that harness the energy of moving water or temperature differentials in the oceans promise to deliver abundant carbon-free electricity. Long before humans got hooked on fossil fuels, we learned how to harness the power of water to do work. Rivers ran mills that ground flour, sawed logs or spun looms that transformed fibers into textiles. Later generations realized that moving water ...

Is energy–led economic growth causing climatic shift? A causal analysis for India
This paper examines the proposition that the climatic shift has been responsible for creating adverse effects on economic growth, and the authors have analysed this situation for India. They consider the number of oceanic storms in the Indian Ocean and the annual mean temperature of India for the 1971–2010 periods. Using vector error correction and causality analysis, they have tried to identify ...

Ocean Thermal Energy Conversion Coming To An Island Near You
Ocean Thermal Energy (OTE) Corporation may be landlocked in Lancaster, Pennsylvania, but that isn’t stopping them from looking to the ocean for 24/7 electricity. Their primary technology is Ocean Thermal Energy Conversion (OTEC), which uses the temperature differentials in the ocean to produce steam. The steam, in turn, activates a turbine, which generates clean energy and potable water. ...

A novel FACTS dynamic stabilisation scheme for stand-alone tidal energy conversion systems
Renewable abundant ocean kinetic energy has become increasingly popular as a consequence of strong ecological viable concerns and economical energy solutions in remote island communities. However, the integration of dispersed renewable tidal energy will pose a greater challenge to the power quality of distribution networks in remote areas due to fluctuation of the tidal stream velocity. The paper ...

A veterans’ day call to action
When the Banks say “No,” 300 Central Pennsylvanians say “Yes” On the 60th anniversary of D-Day, during our trip to honor my Uncle Arthur, who was killed in the Normandy invasion, my son and I wept at the grave of Private J. Shon, a 22 year old Scotsman buried in the Bayeux War Cemetery. Laying among 4,647 other fallen soldiers from WWII, his tombstone was engraved with ...

Ocean Thermal Energy and Water Production
Introduction The scarcity of potable water is a growing problem worldwide, particularly in arid regions and among developing countries. Compounding this problem is the increasing contamination of freshwater sources, which comprise only about 2.5% of all water on Earth. Of this small portion, only 0.5% of the total fresh water available is found in easily accessible sources such as lakes, rivers ...

The UK lags behind EU counterparts to achieve 20% renewable energy target
While some countries have almost hit their targets the UK still has a long way to achieve its 15% renewable energy target by 2020. The EU is more than halfway to reaching its 20% target of generating energy from renewables by 2020, according to new figures published today by Eurostat. The EU's 2009 directive on renewable energy set individual targets for all 27 member states, with a goal for the ...

Introduction to some kinds of renewable energy
Clean energy is a kind of energy which does not produce pollutants in the use procedure. It includes nuclear energy and "renewable energy". Renewable energy refers to a kind of inexhaustible energy such as hydropower, wind power, solar energy, biomass energy (biogas), water energy, and tidal energy and so on. Renewable energy doesn’t have the possibility of energy depletion, and ...
