Note the market for water heaters in India is around $200 million annually and solar water heaters have managed to capture more than 30% of the market showing that solar water heaters are now a part of the mainstream. Note many solar products are starting to become more mainstream as their price competitiveness increases every year. Solar Panels which are the most widely used solar product has seen the price come down by almost 80% in the last few years .

Solar Energy is one of the best ways to bring energy to the disenfranchised poor in Africa and Asia which have no access to electricity and energy. Note Solar Panel prices have fallen by almost 90% in the last 4-5 years making solar energy much more accessible to the poor . Solar Panels can be now be bought at less than $200 which makes them affordable to large sections of the poor. They having stopped costing a ton in subsidy money given the low prices. Besides massive capacities exist in China and other places in Asia which can churn out solar panels in the hundreds of millions.

Wind Energy is the largest renewable energy source in the globe right now (if you don't count in hydro and nuclear energy). The total installed wind energy capacity exceeds the solar and biomass capacity by quite a margin at over 200 GW . The recent surge in wind energy installations has been from China which put up almost 40-50% of the global wind turbine installations in 2010 and 2011. Now China has surpassed every other country to become the largest wind energy country in the world with over 60 GW. While Europe earlier led by Spain, Denamark and Germany used to lead in wind capacity, they have been comprehensively overtaken by the Middle Kingdom in the last couple of years. USA comes in next but still far below its potential while the rest of the world has started to pick up now. India is the 5th largest country and has been steadily putting up around 2-3 GW of wind capacity each year.

The Solar Products Business is booming not only from the Solar Power Plants but also in consumer products business. Sol not are big conglomerates like Mahindra, GMR , Reliance getting into the lucrative booming solar power in India, but now water purifier companies in India are too getting into the act. India's biggest water purifying company Eureka Forbes which is found in almost every Indian home is going to start selling solar lighting products like torches and lanterns.

However distribution into the millions of villages remains the biggest hurdle even if the people there can afford the products.T here are no good roads and the smaller solar companies lack the marketing muscle of say a big MNC like Hindustan Lever and ITC.People have tried to sell solar products using the microfinance companies but have not had much success as of now.India's government has also pushed some small subsidy schemes but the red tape and the off and on nature has meant failure.

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

India faces a Long and Dark Summer in 2012 with its Electricity Industry in Shambles.The list of woes is almost non-ending and the government is the biggest culprit.Locked in a policy paralysis due to its corruption taint,the authorities have failed to move.Indian Electricity Companies too are facing losses and may even default on some project debt.The state distribution companies already have racked up billion of dollar in losses due to total mismanagement of tariffs and power theft.So the whole supply chain is in trouble with the Indian Banks also in trouble as they have lent billions to the power producers.

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.

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

Solar Thermal Energy has been losing out in the last couple of years to solar photovoltaic energy which is seeing a huge increase in demand amidst very low prices.Some of the major solar thermal energy projects in the globe have been converted into solar pv installations due to its lower costs.Some of the major solar thermal energy companies like Solar Millennium have sold their solar thermal portfolios to other companies while Stirling Power Systems has gone bankrupt.Tessera has sold its solar thermal plants which had gotten DOE Loan Guarantees in California to Solar Developers who have made these solar thermal plants into solar panel ones.However there are some companies like eSolar and Brightsource Energy which are powering ahead with their technologies and projects with backing from big industrial MNC conglomerates like GE and Areva.Their Power Tower Technologies are supposedly more efficient than the mainstream parabolic toughs that are used.

Natural Gas has got a lot of press these days as massive discoveries of natural gas reserves in shale gas formations has meant that the prices have gone down substanitally and new power plants and infrastructure is being developed to use natural gas as fuel.Even as crude oil and coal prices have gone through the roof,natural gas prices have dived.This is due to the new technology being commercialized which is allowing huge shale gas deposits to be used.This has led to forecasts that natural gas will become a more important part of the energy mix in the coming days.The falling prices of natural gas has also led to declining electricity prices in the USA where shale gas development is the most advanced.Natural Gas prices have gone down to as low as $3.5/mmbtu from $8 in 2008 and experts predict that it may go down to $2.5/mmbtu.Shale Gas has its own critics who say that the shale gas deposits are much lower than being said and they deplete much faster.Environmental concerns are also being raised about the fact that it leads to poisoning of the water supplies with France banning shale gas mining completely.Natural Gas is a byproduct of Oil Drilling and in the earlier days it used to be looked upon as an irritant and burned off.But now it is being used to generate power,in chemical and fertilizer plants and also being used in some parts of power vehicles as well.Natural Gas is also used for Heating in most western developed countries and for Cooking as well.With increasing availability it is replacing coal and oil in power plants and transport now.

Oil is one of the most important commodities in the world playing an important part in some of the biggest industries like chemicals,transport,power,petrochemicals etc.The high energy density and easy availability have made mankind almost completely dependent on oil for most of his needs.Almost all of the world's cars run on petrol /gasoline which is derived from crude oil.Despite new evidence that burning oil leads to massive pollution and greenhouse warming nothing had been done to prevent its usage growth.In fact each year billions of barrels of oil are burned to power cars,ships,trains etc.Some countries use oil to power electricity as well though that has been decreasing as oil prices have increased substantially in recent years.The massive oil dependency has been decried by politicians for a long time but little has been done to reduce it.Powerful oil lobbies run by massive industrial conglomerates like Exxon,Chevron,BP etc. have managed to kill legislation which would reduce the subsidies to the fossil fuel industry.The BP Oil Spill after creating a massive hue and cry has faded from the public mind and its now business as usual for the Oil Industry.The only way Oil usage can be reduced it seems is when the world runs out of oil and the prices become too high for most people to use it.

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

Solar Power in India has been growing at an explosive pace due to declining costs of Solar Energy and incentives given by the Government of India under JNNSM.While most of the subsidies for solar energy in India are going to large solar farms,Solar Lighting is also growing steadily without any support.This is due to the fact that Solar Lighting saves on electricity costs and is also environment friendly.Solar Lighting in India is gaining traction not only in the upper income segments but also at the bottom of the pyramid.Solar Lanterns and Lamps are replacing expensive,GHG emitting kerosene lamps in poor rural as well as urban India.Depsite shoddy subsidies,solar lamps have become economic to compete with fossil fuel alternatives.Solar Lighting is also being heavily used for Street Illumination in places where the electricity grid is not present.Solar Lighting is also gaining acceptance in use in gardens where they can capture sunlight in the morning and light the gardens in the night using the stored energy.

India suffers from a massive electricity deficit with large swathes of the country undergoing power blackouts of as long as 8-10 hours on a regular basis.The problem becomes even more acute in the summer season when air conditioners are being used in an increasing number of homes and offices.The industry too is using more and more amounts of electricity as the Indian economic growth rate has exceeded at 8% in the last few years.The electricity situation has not improved and looks like it will become more miserable.The sorry state of affairs is that the cost of fuel is rising but the electricity regulators are loath to increase prices.This means that Indian electric utilities will supply low power as they will be reluctant to buy higher cost electricity.According to CEA,India had a peak demand of around 116 MW in Apri-Dec 2009 with 101 GW of Supply resulting in a 12.5% Demand Deficit.The Fast Growing Economy has resulted in even higher demand for power which has not been met by increased demand.

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 .

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.

Solar energy usage is an excellent, eco-friendly and cost-effective way to "Go Green". It is a very effective measure to save energy & money. We use the solar energy every day in many different ways.Solar Energy is indirectly responsible for other forms of Energy that we use as well like Coal,Oil,Gas,Hydro Energy etc.The biggest use of Solar Energy is in Agriculture where Sun Light is used by plants to grow and provide food for us.Solar Energy despite many years of development is not used in the generation of Electricity due to its higher costs.However that is going to change as Solar Energy is the only form of Energy whose costs are continuously declining compared to other forms of Energy.This is one of the biggest advantages of Solar Power over other renewable and non-renewable forms of energy.Solar Energy forms just 0.1% of the the total energy supply of the planet currently and analysts and decision makers don’t think that Solar Energy can form a big chunk in the future as well.However I differ strongly in that aspect.The main reason for my very bullish opinion on Solar Energy is based on the simple fact that Solar Energy is the only form of Energy whose costs are declining rapidly on a secular basis.In a world facing the prospects of “peak commodity”,solar energy remains vastly abundant and it remains upto human technology to capture it at the lowest costs

A solar cooker uses solar energy to heat food or drink to cook it . The vast majority of the solar cookers presently in use are relatively cheap devices though expensive devices are more prevalent in developed countries. Solar Cookers use no fuel and require little maintainance, they can help reduce fuel costs for the poor which are mainly depended on firewood for cooking.This will reduce pollution and lead to saving of the forests.

Solar Products in India are set to grow at a tremendous rate in the future driven by the declining costs of solar power and the increasing price of fossil fuel energy products.Already we are seeing massive power cuts across the country due to shortage of coal.Beside this,the prices of electricity has increased tremendously as well and is approaching seriously high levels due the increasing price of coal and gas.This has made it inevitable that people will turn towards solar products which are not only becoming cheaper but are also greener.Solar Products comes in a wide variety and range from almost all electrical home appliances.You can solar air conditioners,solar fans,solar toys etc.The main uses of solar products however are those in generating electric power .These are known as solar panels and poised to become ubiquitous in the days to come.The day is not far off when almost every house in India will have solar panels on their roofs to generate cheap electric power.Beside this solar lanterns are already replacing expensive and polluting kerosene lamps in poor households.Solar Lighting is also increasing particularly in those areas where the electricity power grid cannot reach.Solar Heaters have become extremely popular in southern India as solar water heaters are much cheaper than normal electricity powered water heaters.Though Solar Cookers have not caught on in a big way,there are also very cost effective and clean.Below is listed out the main solar products sold in India along-with their suppliers

Solar Thin Film Companies are coming under siege again due to the relentless fall in the prices of crystalline silicon panels in recent months of 2011.Note large number of thin film companies went bankrupt the last time polysilicon prices fell off a cliff in the post Lehman crisis period in 2008 end.Applied Material the biggest solar equipment company killed off its SunFab Division which has a large customer list.Applied Materials saw the writing on the wall and concentrated its efforts on crystalline silicon equipment buying HCT Shaping and Baccini to become a billion dollar supplier of solar equipment.A number of weaker hands in solar thin film went out of business.However the prodigious growth in solar demand in 2010 saw large investments being made again.The biggest failure (not complete yet) seems to be the DOE and Obama darling CIGs startup Solyndra which has already used up a billion dollars with nothing much to write home about .Now Republicans are investigating whether the more than $500 million US government loan was done improperly.Abound Solar a CdTe startup has also managed a $400 million loan and I doubt whether it will manage to ever pay off the loan given that the lowest cost manufacturer of solar panels First Solar itself is under pressure from sharp cost reduction by integrated solar panel companies like Trina Solar.

NGO Krishi Bikash Shilpa Kendra (KBSK) members have been involved in the past in job heist schemes where they have fleeced money from unsuspecting villages using jobs as incentives.5 members of the organization had been arrested in West Bengal .The organization had also used the names of central officials and the national emblem to embezzle money from poor villages.It does not have an inspiring track record with a former secretary in jail as well.There is little details about how this NGO will go about this program or how it would get funds to do it as well.
