World clean energy - Plans and Action

World Clean energy


A 2009 Stanford University study ranked energy systems according to their impacts on global warming, pollution, water supply, land use, wildlife and other concerns. The very best options were wind, solar, geothermal, tidal and hydroelectric power—all of which are driven by wind, water or sunlight (referred to as WWS). Nuclear power, coal with carbon capture, and ethanol were all poorer options, as were oil and natural gas. The study also found that battery-electric vehicles and hydrogen fuel-cell vehicles recharged by WWS options would largely eliminate pollution from the transportation sector.

Our plan calls for millions of wind turbines, water machines and solar installations. 

when burned in vehicles, even the most ecologically acceptable sources of ethanol create air pollution that will cause the same mortality level as when gasoline is burned. Nuclear power results in up to 25 times more carbon emissions than wind energy, when reactor construction and uranium refining and transport are considered. Carbon capture and sequestration technology can reduce carbon dioxide emissions from coal-fired power plants but will increase air pollutants and will extend all the other deleterious effects of coal mining, transport and processing, because more coal must be burned to power the capture and storage steps.

A total of 837 megawatts of solar PV were installed in Australia in 2011, more than double the capacity added in 2010, according to the PV in Australia 2011 report.




At the Korean Summit, Japanese billionaire and renewables evangelist Masayoshi Son spelt out his proposal to connect renewable energy generation in Mongolia to Japan: wholesale power in Japan costs 20c KWh; solar and wind generation in Mongolia costs 3c KWh, with transport to Japan costing another 3c KWh. Bingo, clean energy plus big profit and Japan gets to keep its nuclear plants shut.

Saudi Arabia

Saudi Arabia plans 25GW of concentrating solar power (solar thermal), and 16GW of solar PV by 2032

Extensive wind, geothermal, waste-to-energy and nuclear options investments will also be announced.

The $110 billion program would ultimately account for one third of its electricity requirements.

Iceland today generates 100% of its electricity with renewables: 75% of that from large hydro, and 25% from geothermal. Equally significant, Iceland provides 87% of its demand for hot water and heat with geothermal energy, primarily through an extensive district heating system.

 Iceland is contemplating building the world's biggest undersea electric cable, so it can sell geothermal power to other European nations. If it works, it could export enough electricity to power 1.25 million homes.

Landsvirkjun, Iceland's state-owned energy company, is studying the feasibility of building a cable. Depending on the recipient country, the cable would be between 745 and 1,180 miles long.



The Korean has set a target of 2 per cent of GDP going into Green Growth efforts.



Maldives government announced in March 2009 that  that they would spend 110M USD  a year to become the first country in the world with a zero-carbon economy by 2019.



According to the local news agency, BJX, the East Inner Mongolia grid has managed to achieve 39% of its power generation from wind power so far this year. The wind generation mix reached its peak on 14 May 2012, accounting for 72% of the total power generation. That’s even better than South Australia.



Plans to develop 2,000-megawatts from solar energy by 2020, which corresponds to 38 percent of the country's current installed power generation capacity.


How Australia trails the world in big solar

Renew Economy

Australia has the best solar resources, the most land, and has been a breeding ground for some of the most advanced technologies. We like to think we are a leader in the solar industry, and while we have enjoyed some of the biggest deployments of rooftop solar in the world in the last two years, in terms of utility scale installations, the country is barely out of the gate.

Just how far behind – in practice and in vision – was reinforced last week when  UK Energy and Climate Change Minister Greg Barker repeated his government’s “aspiration” that the UK solar market could reach 22,000MW by 2020. There are plans to begin construction of the first large scale solar plants in Scotland, of all places, early next year.

Australia’s ambition? Well, according to the draft energy white paper released 11 months ago – the master document for Australia’s energy planners – and the closest thing Australia’s federal energy ministry comes to having a vision – it expects around 3,000MW.

So badly mistaken was that scenario that the number is likely to be overtaken as soon as the end of next year, and there has been much said – both about the actually deployment, the costs, and the future cost curve – to suggest that Energy Minister Martin Ferguson has the opportunity to address that missing link when the final draft is released this Thursday.

The issue around big solar will be critical. Solar is arriving on people’s rooftops in ever increasing numbers, its costs are falling, and it emerges as a potential election issue in marginal seats. It is also capturing the imagination in situations like Port Augusta, where the local mayor is leading a popular push to build a solar thermal plant.

Last month, Australia opened its first utility scale solar farm – a modest 10MW solar PV facility near Geraldton. While ground-breaking for Australia, it does not rank even in the top 200 of utility scale solar systems in the world.

So apart from the UK, who else does Australia trail behind in big solar?

There are the major economies, such as the US, which has built nearly 3,000MW of large scale solar and has committed projects for another 28,000MW, and China, which last week reinforced its ambition to have 21,000MW of solar installed by 2015, a roughly even mix of distributed and utility scale plants. Why does China install so much solar and Australia doesn’t? Well, it needs all the energy it can get, as do other nations. Australia has too much energy, and more renewables will simply accelerate the decline of coal and gas.

India, another energy hungry nation, has its own plan to install 20,000MW by 2022, and has already built several large scale plants, and more are under construction. Germany, Spain and Italy all have large amounts of rooftop solar, as well as many commercial and industrial and utility scale systems. Germany has more than 35,000MW of solar, and Spain is a leader in solar thermal and solar storage plants. Japan has also just introduced the world’s most generous feed in tariffs, and plans for solar plants in the 10MW to 100MW range are announced almost daily.

The other countries ahead of Australia – in big solar –  may surprise.  These include Ukraine, Bulgaria, Romania, Czech Repbulic, France, Greece, Portugal, Peru and Thailand. Serbia has just announced plans to build a 1,000MW solar park by 2016, South Africa has signed off on the financing of 600MW of solar projects and is about to invite bids for another round, while Chile has some 3,000MW of large scale solar in the pipeline – mostly built for mining clients without subsidies,such is the cost of energy in that country.

Then of course, there is Saudi Arabia, which plans to spend $100 billion to invest in 40,000MW of large scale solar, so it can free up more oil for export and other uses. A senior Saudi minister last month suggested the country may aim to be 100% emissions free in its power systems within a few decades. Dubai has just ordered a 13MW solar plant, the first in a $3 billion program, and large scale plants are being built across the middle east and north Africa, which is being linked with the Desertec project in Europe to import solar power.
