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.

Oil Rich Middle Eastern Nations like Kuwait,UAE and Saudi Arabia have been planning to build nuclear energy plants for quite some time now. They have been extensively engaged in discussions with Asian consortia to supply technology and expertise for building nuclear power plants in their countries. The reason for their nuclear love is that these nations are seeing rapid growth in energy demand. The reason is their fast growing population which is increasing their consumption of oil and gas produced. This is reducing the export dollars from the supply of fossil fuels. The countries want to increase renewable and nuclear power so that they can conserve their depleting supplies of oil for exports. However the Fukushima incident has given some of them cold feet. While countries like Vietnam and China are pressing ahead with their nuclear expansion plans, Japan,Germany,Switzerland have decided to give up nuclear power. Widespread nuclear protests in Germany made the government take the drastic action of stopping a number of nuclear reactors. Kuwait Develops Cold Feet on Nuclear Energy,will UAE and Saudie\s capitulate as well

USA has the largest amount of spent nuclear waste in the world and it does not have a single permanent nuclear waste storage site. It is quite shocking that thousands of tons of dangerous nuclear waste is put in temporary locations waiting to start a new disaster in the Fukushima pattern. Note the greatest danger and fallout from the recent nuclear disaster was due to spent nuclear rods . The first site that was being prepared in Yucata mountains is mired in controversy despite millions of dollars being spent.

Quick quiz. What is common to Suzlon, Moser Baer, Indo Solar, Websol Energy systems and Orient Green Power? All these stocks had successful runs on the stock market and hyped as the next game changers in wind energy, semi conductors, solar power and hydel/geo thermal power. Valuations were more on growth stories than through an hard nosed DCF spreadsheet. But now, they trade at record lows(like other stocks but what is different is the pressing fundamental concerns in each case). Is this a bubble finally bursting, or are investors panicking?

Green Industry in US continues to flourish despite the general apathy towards global warming from a significant section of the population and parties. USA is the hotbed of green innovation despite stiff challenge by China which is spending billions of dollars to become the No.1 in Green Industry and Technology. US has the lead in Fuel Cell Technology with a number of top companies like Fuel Cell Energy, Bloom Energy. Now a start up ClearEdge Power has got one of the biggest fuel cell orders in the world worth $85 million from Austria's Gussing Renewable Energy. The deal calls for supplying of 50 megawatts of power by the year 2020.

Note one of the main dangers of nuclear energy is the probability of the fuel getting into the hands of terrorists and rogue nations which can use it to make nuclear weapons.Note the fears of a Taliban like group getting their hands on nuclear arms in Pakistan is all too real.With Iran getting nuclear weapons,this will increase.Nuclear Power is already being phased out in Germany,Japan,Switzerland after the Fukushima nuclear disaster.The dangers of nuclear energy are too great to make it an option to secure mankind's energy in the future.Despite the advantages of nuclear power,the risks are too great to be played with.

Japan which has faced two of the worst nuclear accidents in history,the atomic bombing in WW2 and the Fukushima disaster,is thinking of nationalization of the nuclear industry.This comes after the fallout of the Fukushima,where the utility TEPCO needed a massive bailout.To pay compensation and repair the disaster would have bankrupted TEPCO and still left a massive hole.The Japanese government had to step in with a big money package so that TEPCO could meet its liabilities.Note the biggest disadvantage of nuclear power is the catastrophic tail risk of a nulcear meltdown.

power projects.See below for the problems besetting India's thermal power project developers.Note wind and solar power projects are seeing more interent from debt syndication lenders like IDFC,IL&FS because of 2 reasons
a) Strong support from state and federal governments which are going all out to support Renewable Energy through tax breaks,feed in tariffs,capital subsidy
b) Secure Power Purchase Agreements (PPA) by NVVN at even higher prices for green energy
c) No problems of fuel supply availability that plagues the coal and gas power plants in India
d) Lesser Environmental issues that beset the Coal Power and Nuclear Power Plants in India with local agitations
e) Land Acquisitions problems are also lower as solar and wind power plants don't require prime land

Biomass Plants in India are shutting down as feedstock costs have increased rapidly while government regulated electricity tariffs have yet to increase.60% of India's Biomass Plants have closed down as they are longer profitable.Note India has a massive growth target for biomass electricity capacity up from 1 GW at present (2 GW if you count cogeneration).A number of agricultural companies have set up a number of plants besides dedicated green utilities.However inflation in India has affected the operation of plants specially those who don't have inhouse feedstock supply.

Nuclear Power has come under assault in the aftermath of the Fukushima Nuclear Accident with Nuclear becoming a four letter word.However Nuclear Energy cannot be ignored because its nuclear energy uses are unique in some applications and cannot be substituted by any other means.Nuclear Energy is responsible for generating almost 1/6th of the global production of electricity with Developed Countries like Japan,Europe and USA having 20% or more of their electricity being generated by Nuclear Fission.Currently 31 countries in the world have nuclear reactors producing electricity.The total installed nuclear generating capacity in the world is around 375 GW (WNA) with another 170 GW in planning g state and another 170 GW being proposed.Despite the massive opposition that nuclear power has run into,nuclear companies and nuclear power stocks are not going away soon.This is because of the massive installed base and the nuclear plans of emerging countries.For example Middle Eastern countries like Saudi Arabia,UAE are going ahead with their nuclear power plans as are countries like India and Vietnam.

Wave Energy is one of the niche Water Energy Technologies that is still in its infancy stage in terms of technology maturity.Wave Energy has been around a long time with around 350 patents being granted for this technology and around 200 startups working on this renewable energy form.Wave Energy basically derives power from the movement of waves to generate electricity or power.Wave Power exists due to the differences in the speed of ocean water and wind power.The energy is transferred by the Wind Energy to the Waves which can be utilized to generate power.A wide variety of wave energy generators like buoys,underwater devices are being developed to harness the power of the waves in a cost efficient manner.Wave Energy Research is concentrated mainly in the United Kingdom which has made tidal and wave power central to meeting its 2020 European goal for renewable energy.Edinburgh in UK has become a center of wave energy development and EMEC has developed Cornwall as an important site for demonstration of wave energy projects.Some of the wave power companies are listed on the stock market as well.Due to the technology immaturity ,most of these stocks are micro cap and not an investible class for big investors.

Nuclear Weapons are a massively controversial topic with the opposition towards Nuclear Weapons handily beating the supporters of these arms of mass destruction.Nuclear Weapons have been foretold as humankind killers since their development during the Second World War by USA.With the erstwhile USSR developing these nuclear weapons as well,a Cold War developed between the 2 superpowers.The War was Cold as both sides possessed enough nuclear weapons to destroy the world many times over.Despite strong arguments against nuclear weapons,most of the developed nations including the most powerful ones like USA,Russia,UK,France and China have refused to abandon nuclear weapons.There have been many movements for the complete abolition of nuclear weapons which can destroy mankind as we know it.However except for the START reduction of nuclear weapons by USA and Russia nothing much has been achieved.In fact new unofficial nuclear weapon powers like India,Pakistan and Israel have joined the Nuclear Club.South Africa too had developed nuclear weapons before abandoning the idea.Rogue nations such as North Korea are said to have developed nuclear bombs while Iran too is trying to make nuclear weapons to counter USA domination of the Middle East.
Most of the arguments against nuclear weapons are too vehement and extremist to get an idea whether nuclear weapons have any advantages if at all.A listing of facts about nuclear weapons is necessary for kids to get an idea about the dangerous cons of nuclear weapons.While there is no doubt that everyone would like to completely remove nuclear weapons from the world,there are benefits which nuclear power see in them so we need to examine them also.Unless we can analyze and correct the pros of nuclear weapons we are unlikely to get a correct solution to the these Armageddon weapons

Wave Energy is being developed for a long time almost since the 1700s through a variety of devices and convertors.Wave Devices are being used mainly to generate electricity and for water desalination.Wave Energy has a myriad of systems being developed as the technology is still immature.Wave energy generation is still a research field and there are as many designs as companies active in this field.Note as a technology matures,a single technology system gain ascendance as others are discarded along Darwinian lines.For example solar technology which is in the phase before maturity has majority of its energy convertors of the mainstream polycrstalline solar panels.Wind Energy which is further along the learning curve has most of its energy being generated from large vertical axis wind turbines.Wave Energy on the other hand has not come around a single dominant type of device.A number of devices are being developed to harness wave energy efficienty and at low cost.Wave Energy faces problems of being exposed to strong weather elements therefore wave energy designs are progressing along the lines of devices which require low maintainance and which are able to withstand weather better through devices with lower number of moving parts.

Nuclear Energy has come under the spotlight after the Japanese nuclear plant disaster with people focusing on the strengths and weaknesses of nuclear power.One of the most important aspects of nuclear based power is that it is highly efficient.Nuclear Energy is currently the most efficient power source in terms of the fuel required,land area needed and also the waste it produces.The reason for this is that nuclear based electricity is primarily produced from nuclear reactions while other forms of energy like natural gas,coal and oil use chemical reactions.Other such as wind energy convert mechanical energy into useful energy.Nuclear Power currently is mostly produced through nuclear fission as nuclear fusion is still in infancy and its not certain that mankind will be able to use nuclear fusion in a safe manner to generate energy.

Nuclear Energy has become a hugely contorversial topic after the Fukushima incident in Japan where a nuclear disaster took place because of the earthquake and tsunami.Both the pro and anti nuclear groups have come out with strident arguments for and against nuclear energy.However in some countries like Germany,Switzerland the anti nuclear sentiment has gained so much support that they have decided to permanently end nuclear electricity generation despite the high costs.Before this nuclear based power was gaining ascendancy leading many to call it a nuclear renaissance as countries like China and India made plans to increase their nuclear power plant capacities massively.But the nuclear accident has thrown a spanner in the works with huge protests being seen in India and China despite its authoritarianism also slowing down its nuclear expansion plans.

Wave Energy is a niche renewable energy type which has been seeing slow development for the past many years.The immature nature of the technology means that most of the wave energy projects have been mostly been pilots.The same state of affairs exists in India as well with a few pilot projects being constructed.Though the government of Gujarat is constructing India's biggest tidal barrage off the coast of the Arabian sea,wave energy projects have been few and far between.Indian Wave Energy traces its history since 1984 when a Oscillating Water Column (OWC) type of device put into tuse at Vizinjham Fisheries Harbor near Trivandrum in Kerala.In 1993 the National Institute of Ocean Technology was established

Wave Energy is one of the niche renewable energy technologies which is still in its infancy stage.While other forms of alternative energy like solar,wind and biomass see hundreds of billions of dollars in investment each year,wave energy does not see even $1 billion in investment.This is because Wave Energy is still much behind in the technology curve in terms of costs and reliability.Also there are many varied approaches and technologies to harness the power of the ocean waves.However developed countries like UK are promoting this renewable energy since it has huge potential like solar and wind energy.Given the energy shortages that we are facing,we need to promote all forms of sustainable green energy and wave energy definitely has strong promise.Here we present the various pros and cons of wave energy

Nuclear Power like other forms of Energy cannot be defined by a single cost as nuclear power plants differ in their technology and sources of fuel.No two power plants can have the same cost of electricity production similarly nuclear energy plants cannot have the same kilowatt hour cost.However nuclear energy is known for its very low costs of 2-3c/kilowatt hour which can only be currently be met by coal.But nuclear energy cost is based on older nuclear power plants which have already been depreciated.This cost is also controversial as the costs of nuclear waste storage is generally not included.USA and Japan which are the largest nuclear power producers have not constructed permanent nuclear waste storage sites despite accumulating thousands of tons of nuclear waste.Also these days extra safety measures are being taken due to the Fukushima disaster which means that the costs of nuclear energy is going up.

Solar Thin Film Technology has been growing rapidly despite falling costs of the mainstream Photovoltaic Crystalline Silicon Technology.While the current solar supply glut has resulted in some of the thin film solar film companies going out of business,big thin film suppliers continue with their growth plan.Solar Thin Film Technology is supposed to be the 2nd Generation successor to the mainstream Crystalline Silicon (c-Si) Technology which accounts for around 85% of world production.While a number of Weaker Hands in Thin Film have downed shutters,Thin Film Producers continue to grow and expand.The massive growth potential of Solar Energy makes it possible for both of these PV technologies to flourish.Thin Film Technology unlike c-Si has a number of variants.Amorphous Silicon (a-Si),Copper Indium Gallium Sulphide (CIGs) and Cadmium Tellurium (Cd-Te) are the 3 main types of Thin Film Technology.There are a number of manufacturers of all of these 3 types of Technology.CIGs Technology is said to have the most potential in improving efficiency and competing with c-Si,however Cd-Te is currently the top dog as the world’s biggest solar producer First Solar currently uses this technology.a-Si Technology is not that hot with low efficiencies however Oerlikon and Sharp are pushing ahead with developing this technology.

By definition it goes that Solar Energy is renewable. The sun rises every morning & sets every evening. It has continued like this since last billions of years & will continue for more billions of years. Hence there is an unlimited supply of sunlight. Unlike coal & oil which is fast depleting, there is an abundance of sunlight. Hence the prices of these products are getting dearer, whereas the solar energy will definitely be very reasonable in the near future. The day is not far off when all our homes & offices will be lit by this solar energy & that too for almost free.
Strictly speaking nothing in this universe is renewable but if the time-line of the energy source is sufficiently long for example in the case of the sun which will be billions of years then it is renewable.Solar Energy is definitely more renewable than Hydro or Geothermal sources of energy .

Renewable Energy is a sunshine industry in India right now and a number of non traditional players are getting into the clean energy industry right now.Companies with surplus cash or lack of growth opportunities are turning to solar energy generation to fuel growth.The JNNSM first phase saw a large number of companies bidding and some unknown players winning the auction.While a large number of these solar companies will never their projects see the light of the day (pun intended),some will survive and thrive.More companies are getting into the solar power busness attracted by the long term potential of solar energy in the country.Kanoria Chemicals which recently sold off a large chunk of its chemical business is sitting on a huge pile of cash.The company has decided to get into renewable energy generation by setting up a 2-3 MW solar plant.Note Kanoria Chemicals has little to any relation between its core operations and solar energy.

Nuclear Power Plants around the globe are being closed at a furious rate particularly in Europe.The Fukushima Disaster has caused a nuclear winter in the nuclear power plant industry.Even Nuclear Power Plant Equipment Leaders like Toshiba are changing their strategy to concentrate on Renewable Energy.Even new Nuclear Power Plants being built in India and China are facing massive opposition.New Nuclear Power Plants being built at Jaitapur and Tamil Nadu have met massive organized protests by local citizens throwing the future of nuclear power plants in jeopary.The Communist Government in China too is going slow on the biggest rollout of nuclear power plants in the world.High Cost Escalation and long project delays had already made building new Nuclear Power Plants in the Developed World almost impossible.Japan and Germany which are two of the largest nuclear countries have decided to shut down all nuclear power plants.Switzerland and Belgium too have decided to kill the nuclear power industry in their countries.In this light it becomes very important to examine the pros and cons of nuclear power plants.A cost benefit analysis of nuclear energy is crucial as new plants cost billions of dollars and can cause massive costs if things go wrong as was the case with Chernobyl and Three Mile Island Disasters in the 1980s.
