List of Earth's Largest Wind Energy Countries – China Leads with 60 GW of Wind Electricity Capacity

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.

Nuclear Energy Companies,Stocks to Invest In Complete List (Utility,Reactor,Waste,Uranium)

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.

Nuclear Energy Efficiency vs Fossil Fuels (Oil,Gas) in Power Load Factors,Energy Density and Waste

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.

Advantages and Disadvantages of Natural Gas Energy – Pros and Cons of Gas Usage

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.

Advantages and Disadvantages of Oil – Cons Disregarded by Powerful Lobbies

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 Pros and Cons – Tidal and Ocean Wave Power Still Niche Technologies

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

Pros and Cons of Hydroelectric Energy

Hydro Electric Energy is second largest source of electricity in the world accounting for roughly 20% of the worldwide demand of electricity with around 800 GW of capacity installed.Hydroelectricity power plants are the biggest power stations in the world dwarfing the biggest nuclear and coal power projects.The world’s biggest power plant is the Three Gorge Dam in China which at 22.5 GW is more than 50% larger than the 2nd biggest power station in the world.s.China is the by far the world leader in hydro power plant capacity with around 200 GW which it aims to double to around 400 GW by 2020The advantages of hydroelectricity energy are substantial enough to far outweigh any disadvantages.But like nuclear energy,hydro power has some tail risks which can lead to catastrophic damage.

How to Save Electricity and Reduce Home Power Bills in India (Simple Ways for Lighting,Home Appliances and Entertainment)

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.

Is Solar Energy Renewable – Differences with Nonrenewable Sources

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 Pros and Cons – Europe Decides Cons too Disastorous

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.

Uses of Solar Energy – Applications,Future Uses,Countries and Why We should Use Solar Power

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

Solar Cookers How Poor in India can Fight against Gloal Warming – Solar Cooker Advantages,Disadvantages and Types

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.

World's Largest Power Plant Hydro Dam Grand Inga 39 GW in Congo Depends on Inga 3 Design Choices

Note the cost of Hydropower at $1-3/watt are quite large and if not planned and implemented correctly can lead to huge time and cost escalation.The Inga 3 Dam being proposed to be built on the Congo River in the DRC faces tough choices.The Hydro Dam on the Congo which will become the biggest hydro power project in Africa is wresting over design issues.The major choice is between tunneling through rock structures or keeping open channels.Note the total cost of the 7 GW Power Plant will be around $14 billion making it the biggest investment in Congo and the 5th largest Hydro Power Plant in the world.Note Africa suffers from chronic power shortages which will become more acute with rising cots of fossil fuels and increasing per capita electricity demands.Making correct decisions on energy is vitally important for the development of the African continent.China is the country with the largest hydro power capacity at 200 GW which it wants to further increase to a massive 400 GW by 2020.

European Carbon Trading Market goes into a Huge Slump on Greek concerns,post 2012 Kyoto uncertainity

The European Carbon Trading Market which is the biggest cap and trade market in the world has gone into a monster slump with carbon credit prices having fallen to around 10 euros which is the lowest since March 2009 when almost every global asset had fallen to multi year lows.The trigger for the correction in prices is the future of the EUA scheme in which major carbon emitters in Europe are restricted to quotas and have to buy carbon credits if they exceed their limits.A huge amounts of United Nations CERs are sold into this market as they are allowed to to so.This has led to the mushrooming of a huge growth of carbon consultancies in India and China which help projects in obtaining these lucrative CERs.Note this has recently become highly controversial with a number of frauds happening in trading of these carbon credits.Top investment banks have been convicted of fraud and big sellers of CERs like the HFC producing companies have made ludicrous windfalls of hundreds of millions of Euros.Some of these companies have now started focusing in winning these CERs which are much more profitable than their core operations.

Indian Telecom Companies appropriating $500 million of Fuel Subsidies for Poor and generating > 5 million tons of Carbon through Massive Diesel Burning in Telecom Towers

Indian Telecom Companies are using more than $500 million in fuel subsidies meant for the poor and generating more than 6 million tons of carbon dioxide every year by using diesel gensets at telecom towers not connected to the grid.Note the Telecom Industry in India has not exactly covered itself with glory on other matters with the 2G Telecom Scam already putting top executives in jail and implicating top telecom companies as well.The issues of massive fuel wastage in telecom towers has been raised in the past in greenworldinvestor as telecom tower companies viom,gtl,airtel and others have tried to put lipstick on the pig by making a mockery of green initiatives by committing to convert only a minuscule number of total towers to renewable energy.

CERC to increase Renewable Purchase Obligation (RPO) frequency compliance to facilitate lumpy REC Trading

Central Energy Regulatory Commission (CERC),India's Electricity Regulator is planning to increase the frequency of compliance of the Renewable Purchase Obligation (RPO) for states from an annual affair to a bi or quad annual affair.Note Renewable Energy Certificate (REC) Trading in India started in 2011 to facilitate the development of the Renewable Energy Industry in India.According to the RPO,a certain percentage of a state's electricity generation must come from clean energy sources.States and utilities which can't meet their renewable energy requirements can buy REC from Indian Energy Exchanges to meet their needs.Power Exchanges in India have already set the ball rolling in terms of trading in RECs.

Power Finance Corporation Green Energy – PFC Subsidiary to become one of the biggest Green Energy Financiers in India

Power Finance Corporation Green Energy has been floated as a subsidiary of one of India's biggest power sector financier Power Finance Corporation.As the name implies the company's mission is to provide loans to India's Green Energy Industry.Note India requires around $10 billion dollars according to the government plans of building 17 GW of Alternative Energy Capacity in India between 2012-2017 which is low in my view.However even this low target will require a massive amount of debt financing to the tune of around $6-7 billion annually.Power Finance Corporation is one India's largest infrastructure financing companies owned by the government.The company which has billions of dollars of loan assets to the Power sector in India has naturally entered the fast growing Green Energy area as well.

Why India's Green Energy 12th Five Year Plan Target of 17000 MW is Too Low

Renewable Energy in India has seen decent growth in the past mainly driven by Wind Energy which accounts for almsot 65% of the estimated 20 GW of Green Energy capacity installed in the country.However to meet India's 2020 Green Energy Target of 15% of power to be generated from renewable sources set by CERC,at least 40 GW more would need to be installed (that is a conservative estimate as load factors for green energy are lower).This is assuming that India meets its target of raising the power capacity to 400 GW by 2020 from around 175 GW at present.Solar Energy in India has not got off to a good start despite immense potential as the federal subsidy program JNNSM has seen irrational bidding by bit players and debt financing is difficult.Wind Power in India has seen the most growth amongst the green sources of power but it too faces hurdles as good quality wind sites have all been taken.

Need for Renewable Energy – Peak Oil,Global Warming,Energy Security

Renewable Energy Investments surpassed investments in Fossil Fuel Electricity investments in Europe and USA in 2010 as developed countries focused on alternative energy as a solution to the problem of Global Warming and higher Fossil Fuel Costs.While Wind and Solar Energy are currently the dominant forms in different types of Renewable Energy,others like Tidal and Wave Energy are also seeing a lot of investment in R&D.The major advantage of Renewable Energy is that it does not emit GHG which is the leading cause of Climate Change.While this is the biggest Need for Renewable Energy other needs are equally if not more important.Here are the most important needs of Renewable Energy

Clean Coal Technologies – Greenwashing or Reality – List of Coal Technologies – IGCC,CHP,FBC,UCC,CCS

Coal is the largest source of electricity supply in the world with 41% of the global power coming from the burning of coal.The Pros of Coal have made the growth of Thermal Power Plants accelerate in developing countries like China and India.This has made Coal Stocks run up by more than 150% in 2010 and another 30% in 2010.However Coal is also the greatest contributor to Greenhouse Gas Emissions.Coal is also responsible for thousands of deaths directly and indirectly due to Coal Mining and Coal Combustion which leads to waste products like Mercury,Arsenic etc which are extremely toxic to human health.To solve the twin problems of cheap energy and global warming, a number of technologies have been been proposed which would reduce the harmful effects of Coal Combustion. Despite a number of Clean Coal Technologies being developed and employed,carbon emissions from Coal Ming and Use can only be partly reduced and will not make a major impact on the problem of Climate Change.Clean Coal Technology is not a Green Solution to the Disadvantages of Coal.Saying that implementing Clean Coal Technology will result in Climate Change Mitigation is Greenwashing.That said these technologies need to be implemented till the world is ready to move away from its addiction to cheap energy provided by Coal even though it has a deleterious long term affect.

Types of Renewable Energy – Major,Minor Types of Alternative Energy and Quasi Clean Energy

Type of Renewable Energy have been increasing with development in Technology and the imperative of using Alternative Energy as Fossil Fuels deplete and increase in costs.Besides Global Warming has made the benefits of Renewable Energy seem more attractive with each passing year.Note though there are many niches Renewable Energy types,the Three Major Forms of Renewable Energy are Solar Energy,Wind Energy and Biomass Energy (Biofuels).Nuclear and Hydro Energy are not considered as Renewable Energy according to the strict definition of Renewable Energy.However Hydro and Nuclear Energy both are responsible for more than 15% of global electricity production each.The clean energy industry saw a 30% increase in investments to $243 billion in 2010 which was another record year for Renewable Energy Capacity addition.Around 18 GW of Solar Energy and 38 GW of Wind Energy were installed with Solar Energy Capacity increasing by a whopping 150% from 2009.\wind power continued to lead at $95 billion. The solar sector is experiencing significant growth, with investments growing at 53% to $79 billion (source Pew).

Coal Renewable Energy – How Green Energy stacks up vs Black Coal

Coal is a dominant source of energy for humans accounting for almost for a quarter percentage of human energy consumption and majority of the global electricity production.However Coal is considered as the Dirtiest form of Energy as it leads to Air Pollution,Mercury Poisoning,Global Warming.Renewable Energy is considered as the solution with its non-polluting characteristics,energy security,freedom from peak everything.However Renewable Energy is way more expensive than Coal Energy making it difficult for Renewable Energy to take over Coal.However growing Global Warming Costs will weigh in the future making it inevitable that Green Energy catches up.Here is a list of the pros and cons of Green vs Black where Green represents Renewable Energy and Black represents Coal.Note Green Energy will ultimately win in the end,its only a question of how soon because if the realization comes too late then Climate Change might go far enough to cause catastrophic damage.

Uses of Nuclear Power – Nuclear Transport (Ships,Submarines),Agriculture,Human Health,Electricity,Futuristic Applications

Nuclear Power has come under assualt in the aftermath of the Fukushima Nuclear Accident with Nuclear becoming a four letter word.However Nuclear Energy cannot be ignored becauses its benefits are unique in some applications and cannot be substituted by any other means.Nuclear Power also cannot be replaced in the short term from its most widely used application of generating Electricity.Note Nuclear Power accounts for almost 15% of the Global Electricity and in some countries is the major source of energy.For example France which has 80% of its power coming from Nuclear Fission,its impossible to think of shutting down nuclear plants like Germany which gets around 20%.Note even for USA which has the largest installed base of nuclear reactors shutting down almost 200 GW of Nuclear Capacity is quite unthinkable.Besides Nuclear Energy has massive uses in medical and other applications.This cannot be substituted by other means at all.For example its possible to replace Nuclear Electricity by other means like Solar,Wind even Coal and Gas though its costs will be astounding.But you can't replace Nuclear Energy in Medical Applications like Scanning and X-Rays.Here is a list of the main uses of Nuclear Energy.

Hydroelectric Energy Advantages and Disadvantages

Hydro Power is one of the largest sources of energy accounting for roughly 20% of the worldwide demand of electricity and for well resourced countries it accounts for majority of the energy.For Paraguay 100% of the electricity comes from hydro power and lot of it is exported as well.Compared to other sources of Energy, Hydroelectric Power is one of the cheapest,non Carbon Emitting,non Polluting,Mature Energy Source.Hydro Power plants have been developed to almost full potential in developed countries because of their superior characteristics and many more are being constructed by developing countries like China and India.However Hydro Power like all other thins in life suffers from disadvantages as well.The failure of a Hydro Dam can result in massive losses of human life and cause widespread devastation.Large Dams have always been controversial leading to displacement of people and ecology.They have also been cited as the reason for earthquakes due to large land changes.Here is a list of the advantages and disadvantages of Hydro Power

Japan to Stupidly Cut Climate Change Funding,Carbon Emissions Target like Australia using Natural Disaster Excuse

Climate Change and Global Warming have been put in the Cold Storage by most world governments as there is little will to fight one of the most pressing challenges facing mankind.With the successive Copenhagen and Cancun Climate Change Meets coming up as croppers,the Poor are left to fight the drastic affects of Climate Change in the face of Severe Weather like Droughts,Floods,Increase Sea Levels.Australia stupidly cut the funding for various Green Programs after facing one of the worst floods in the last century.It did not occur to the short term focused politicians that the Floods may have their root cause in Global Warming.Instead of increasing resources to fight Climate Change,they cut the Funding to help in the Flood Rehabilitation Programs

Pros and Cons of Renewable Energy – A Detailed Explanation

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.

Disadvantages of Renewable Energy – Drawbacks of Different Alternative Energy Sources

The Biggest Disadvantage of Renewable Energy is the relatively higher cost of most forms of alternative energy compared to fossil fuel sources of energy.This has prevented the higher penetration of clean energy as compared to the non-renewable sources of energy.Also the massive old energy lobbies have successfully used their massive influence and power to inhibit the growth of renewable sources of energy.The recent lobbying by oil and gas firms like the Koch Brothers and Valero is quite pertinent.Note the oil and gas lobbies receive almost 10 times the subsidy received by clean energy sources like wind and solar despite their massive established bases.
