Solar Energy is the fastest growing renewable energy source in the world and has shown tremendous growth in the last 2-3 years.This has been driven by a more than 50% decline in Solar PV costs which continues to decline further.With further increase in energy prices,Solar Power is becoming closer and closer to retail electricity price.Not only is the price declining,solar power is clean energy a most valuable feature in these days of accelerating climate change.Solar Energy has already reached grid parity in places like Italy and Hawaii and will do so in more places in the coming 2-3 years.The industry is a dynamic one and the list of top solar companies can change quickly.Rapid Technology Change and Fast Declining Costs have pushed out most of the Top 10 companies of 5 years ago and brought in new ones mainly Chinese.Here is a list of the Top Solar Panel Producers in the World.

India too needs to be worried from these missile developments.Note the Defence Minister had said that he was concerned from the rapid modernisation of China’s military forces but was not overtly worried.I think its time for him to worry as China’s armed forces show massive technological improvement.Note China has the largest military force in the world in terms of number but it lags way behind in technology compared to the West.However that is changing with growth of the Chinese Economy the 2nd biggest in the world.China and Indian relations have been quite tense of late with China raising the ante on a number of issues.China has been placing missiles in Tibet while India is deploying fighter aircraft and troops near its borders with China.

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.

John Kerry is doing the rounds of Pakistan and Obama has called for the release of the “diplomat” on the grounds of diplomatic immunity which is a joke.The widow of one of the killed men had done suicide because she was sure that her husband’s killer would not be brought to justice.The US is doing exactly that by threatening to cut off all aid and break off diplomatic ties.It is this kind of behaviour which leads to more anti-Americanism around the world and displays the American hypocrisy over defence of human rights and democracy.I am sure if such an incident had happened in USA,the murderer would be facing a lethal injection in a very short time.However in an unequal world human rights for an American and a Pakistani or three is different.

Geothermal Energy is the proverbial poor cousin to wind and solar energy.Only 10 GW of Geothermal Energy Capacity has been installed and the growth rate is a pathetic 3-4% compared to the over 50% CAGR seen for solar energy and around 30% for Wind Energy.Geothermal Energy produces electricity at a reasonable cost in mature locations and unlike Solar,Wind does not suffer from intermittency problems.However a number of problems dog geothermal energy development.Despite huge promise,Geothermal Energy faces a slow painful death and unless something dramatic happens will remain a niche renewable energy source.Canadian companies which are the leaders in consolidating the fragmented industry like Ram Power and Magma Power are facing huge problems.While Ram Power saw its CEO go,Magma is now looking at other renewable energy opportunities.

Solar Panel Prices have decreased at a jaw dropping 50% in the last 2 years and will probably decrease 10-15% more in 2011.That is an astounding number given the increasing energy and electricity prices being faced around the globe.Though solar energy is costlier than other forms of energy,it starts on a low base.With 2010 solar growth pegged at more than 100% and 16 GW of solar panels installed,Solar Energy is starting to become more mainstream.Like Solar,the entry of Chinese players has decreased the cost of Wind Energy as well.Despite increasing input steel and copper prices,wind turbine prices have declined.Stiff competition amongst Chinese WTG companies has made the price of a Wind Turbine go as low as $600,000-700,000 in China.This has brought a depression in prices in other places in the world as well.
