Nuclear Energy is facing a global backlash after the Fukushima incident in Japan as countries race to review their existing nuclear reactors.Nuclear Power had been enjoying a Renaissance in the 21st century as the Chernobyl and Three Mile Radioactive incidents faded from public memory.China is the principal driver of growth constructing reactors at a rapid clip to meet its growing needs with thermal power fast reaching a saturation point.Other growing developing countries like India,Vietnam are also planning to heavily invest in nuclear plants.However all those plans may change as the Japanese earthquake shakes up the nuclear energy industry more than the landmass in Japan itself.Note despite the catastrophic tails risks of nuclear power,it is not going to go away soon due to the large installed base and no fast substitutes available.Note more than 430 nuclear reactors are currently operational globally today and lots more on the drawing board.Note Nuclear Power accounts for around 18% of US electricity capacity and 30% plus for Europe,Japan and Korea.France is the leader with 80% of the electricity generated coming from nuclear fission.Here is a list of the Pros of Nuclear Energy.

Hydroelectricity is one of the largest sources of energy accounting for roughly 20% of the worldwide demand of electricity with around 800 GW of capacity installed.There is considerable potential still left and developing countries like India and China can be expected to install another 500 GW over the coming years.Hydroelectricity is very important as it does not lead to GHG emissions and contribute to global warming.It also does not have the drawbacks like other renewable energy forms of high costs and intermittency.The advantages of hydroelectricity are substantial enough to far outweigh any disadvantages.But like nuclear energy,hydro power has some tail risks which can lead to catastrophic damage.The costs of hydroelectricity are not a simple function of dollar costs.It should also take into account the massive displacement costs in case of massive hydro dams,the loss of ecology and potential tails risks which can lead to massive payments.

Hydroelectricity is the production of electrical power through the use of the gravitational force of falling or flowing water.Hydroelectricity capacity is around 800 GW accounting for almost 20% of the global electricity capcity.China and Canada have the largest hydro capacities in the world.If you consider Hydropower as renewable energy,then Hydro is the most widely used renewable energy in the world.In fact Hydroelectricity is the 3rd biggest source of electricity in the world after coal and oil/gas.Hydroelectricity power plants can have massive capacities with the Three Gorges Dam in China being the world's largest at 22.5 GW.The Itiapu and Guri Dams in South America are the 2nd and 3rd largest with 14 GW and 10 GW capacities.China is set to double its massive hydroelectric capacity to almost 400 GW by 2020 from 20 GW currently.The advantages of Hydroelectricity are many

Biomass Energy is highly under-appreciated as a renewable source of energy despite being the most important source of energy during most of human history.Till the 19th century biomass energy used to account for 70% of the world's energy consumption and still accounts for around 10% of the world consumption.In developing countries the share of biomass energy is still quite high at 30% and it is the major source for energy for rural and backward communities.Biomass primarily consists of

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 costs have declined by over 50% in the last 2-3 years even as Coal,Oil,Gas and other Energy costs have gone up.While Wind Energy costs have declined in the last year the overall trend is increasing as the costs of copper and steel go up.This is one of the main reasons why solar energy demand has gone up by 150% in 2010.With solar costs going down by another 10% each year over the next few years,expect Solar Energy to grow at a further fast rate in the future as well after growing at 50% CAGR over the last decade.Here are some of the advantages of Solar Energy over other non-renewable energy forms

Leading GHG emitter and Biggest Coal Exporter Australia Kills Most Green Program using Floods Excuse
Australia is the biggest exporter of coal in the world and one of the leading emitter of GHG emissions.Its huge mining industry generate tons of carbon and earns billions for the Australian Treasury.However despite its leading role in global warming,Australia has almost no subsidies for green energy.The federal government has conveniently used the recent Queensland Floods to cut off a number of Green Programs such as Green Car Innovation Fund, Cleaner Car Rebate Scheme, the Carbon Capture and Storage Flagships and Solar Flagships, the Solar Hot Water Rebate, Green Start Program, Solar Homes and Communities Plan.The Solar Flagships Program which was supposed to generate around 1 GW of Solar Energy has also been killed.Note Australia generate 92% of its electricity from Fossil Fuel which is quite high compared to other developed countries.

Carbon Emissions Trading has always had profiteering built into it as private companies try to game a government regulated system for reducing GHG emissions.Carbon Trading which came into being after the birth of the Kyoto Protocol has got a lot of consultants and investment banks involved.While many of the schemes to earn carbon credits seem unethical they are not illegal.However a number of frauds have been unearthed in Europe which is the ground zero for Emissions Trading.The number of frauds have only increased since then with Italy suspending trading and 1.6 million carbon credits stolen from a Romanian carbon registry.The complexity and information asymmetry has always put the insiders in an advantageous position.The red tape and bureaucracy associated with the Carbon Trading Scheme ensures that common people and small business cannot take advantage of the carbon reduction scheme.

India has set up ambitious targets of meeting 15% of its Energy Needs from Renewable Sources up from around 5.5-6% in 2010.WIth India's Electricity Capacity expected to rise to 450 GW from around 165 GW,this would imply that around 67.5 GW of Electricity Capacity would be needed up from around 16 GW.This would mean around 5 GW of Capacity addition every year in the next decade which is a very tall order.20 GW could be met by Solar Energy according to the Jawaharlal Nehru Solar Mission (JNNSM).Most of the rest would have to met by Wind Energy.Biomass Energy has high costs and reliability problems which mini hydro potential is only 1 GW.Note this is just the capacity I am talking about,for meeting the electricity generation,capacity additions would have to be greater as Solar Energy and Wind Energy have only 20-30% Load Factor compared to 60-80% for Fossil Fuel Energy Sources.Nuclear Energy can contribute another 20 GW.
Renewable Energy in India is growing at a rapid pace increasing its share of the total capacity from 2% in 2003 to around 10% in 2010.However the share of electricity generation is still quite low at 3% due to the lower capacity load factors of Green Energy Sources compared to Fossil Fuel Sources.The Total Installed Capacity of Renewable Energy in India is around 16 GW with Wind Energy taking the Lion's share at almost 70% followed by Small Hydro at 15% and Biomass Energy at 12%.Solar Energy in India till now has a capacity of just 6 MW which is estimated to grow to 22 GW by 2022 making Solar Energy one of the Biggest Growth Opportunities in the Field of Indian Energy.

The Government of India has formed a high powered panel to look into replacing the usage of diesel powered gensets by Renewable Energy in Telecom Towers.India has around 300,000 Telecom Towers most of which are powered by expensive diesel generators.The reason is that a lot of the telecom towers are situated in far flung areas where the grid does not exist.Also the power supply in India is erratic and not reliable with 10 hour electricity blackouts not an infrequent occurrence.In these cases a backup supply of electricity supply is badly needed.Diesel Generators are the most popular form with Diesel heavily subsidized by the government in comparison to normal petroleum.Also Diesel Generators are widely available without huge capital costs.

NRG Energy is one of the largest utilities in the US with around 22 GW of Installed Capacity.However like Exelon,the share of Renewables is relatively low at just 2% of its overall Energy Capacity.Though the US Administration has all but given up on an Energy and Climate Legislation,Big Utilities recognize the need to generate low carbon electricity.Some sort of Carbon Emissions Restraint will be imposed on Utilities sometime in the future with EPA itching for action in restricting CO2 Emissions.Green Sector Stocks have fallen like a rock in 2010 due to the Copenhagen Disaster and lack of movement on a Climate Bill by the US government.Therefore it makes sense for US utilities to buy Renewable Energy Assets on the Cheap.Exelon bought Deere Energy Wind Farms at a dirt cheap price.NRG Energy which has around 550 MW of Wind and Solar Capacity bought Reliant Energy last year for $300 mm.It has augmented its Renewable Energy Portfolio with another $350mm buy of Green Mountain Energy.
