Tidal Energy: An Overview Tides are caused through a combination of forces created by the gravitational pull of the sun and the moon and the rotation of the earth. Energy naturally present in water bodies – or in their movement – can be used for generation of electricity, through tidal, wave and thermal energy. Energy […]
Wave and Tidal Energy have been the poor cousins of Solar and Wind Power in the Alternative Energy Domain. I have written about the wave energy companies and advantages and disadvantages of tidal power in the past as well. But the investment opportunities in this area of clean energy have been limited because the technology is still in its infancy. Dr. Ashok has come out with a plan to build a 100 MW device using wave energy and needs funding to develop it. Below is a description of the Plan and the Funding required . Interested Investors can do their due diligence and contact the inventor directly.
Phillipines is heavily dependent on imported fossil fuels for its energy requirements as it lacks sufficient domestic resources of coal or oil.The country which already has a flourishing geothermal energy industry is looking to raise the alternative energy generation from other sources like biomass,hydro,solar and wind energy as well.The country’s Energy Regulator National Renewable Energy […]
Renewable Energy is one of the most read about and discussed topics in the world however various misconceptions remain about the advantages and disadvantages of renewable energy.Note Renewable Energy is a a very large topic and encompasses many different alternative energy forms which have their own distinct pros and cons.A Better Way to understand and explain Renewable Energy would be to look at each different forms of Clean Energy like Solar,Wind,Nuclear,Hydro,Tidal,Biomass and Geothermal Energy.Renewable Energy itself compared to Fossil Fuel forms of Non-Renewable Energy has substantial advantages and some disadvantages as well the biggest of which is Cost.Also note Fossil Fuel Energy has got a massive established base,industry and lobby.
The importance of Clean and Renewable Energy is growing driven by the twin factors of increasing fossil fuel prices and Global Warming.Other factors contributing to the importance and growing use of Alternative Energy is national energy security as geopolitical tensions in major oil and gas countries grows by the day.Also renewable sources of energy like solar energy promote the democratization of energy production which is centralized by power utilities today.There are a number of alternative sources of energy such as solar,wind,geothermal,tidal,hydro and nuclear energy.Some people may not consider nuclear and hydro energy to be green but it is a fact that these 2 energy sources do not produce GHG emissions and cannot be classified as fossil fuels sources.Each clean energy source has its own advantages and many of the pros overlap with each other as well.However each Green Energy source has its unique benefits which define and separate it from the other clean sources.While Renewable Energy advantages over Non-Renewable can be easily be understood as
Tidal Renewable Energy is a niche form of Alternative Energy with less than 500 MW of Electricity Capacity worldwide.Tidal Renewable Energy generates less than .001% of the worldwide electricity generation as the Technology of this Alternative Energy is still quite immature.Tidal Renewable Energy is still an immature technology with most of the plants built around the world being pilot/demonstration ones.The older ones based on Tidal Barrages are also very few in number with the Tidal Power Plant in Le Rance in France the only major operating Tidal Power Plant in the World.Tidal Barrages however are facing major headwinds due to high capital costs and long gestation periods.The newer Tidal Renewable Energy Technologies like Pelamis and Seagen hold big potential though still a decade away from reaching large commercial scale just like Algae based Biofuel and other forms of Green Technology.
Tidal Wave Energy is still in its baby phase with the technology not developed far enough to make it a real alternative to fossil fuel energy.However like solar and wind power 20-30 years ago,Tidal Wave Energy can still develop to become a major form of alternative energy.
