The Paris-based International Energy Agency Energy (IEA) urged worldwide energy revolution and called for more funds to tackle the crisis of climate change in a report published on Tuesday.

According to the IEA's World Energy Outlook 2009 report, due to the violent contraction of the global economy following the financial crisis, industrial production is estimated to consume less energy worldwide this year, which will be the first fall since 1981.

However, big demand for energy will come back as soon as the economy rebounds, the IEA said, forecasting a 40 percent increase in energy demand in 2030.

The future energy demand will still focus on oil, gas and coal, which are major producers of carbon dioxide, the key element that raises the temperature, according to the IEA.

The agency also expects an annual increase of one percent for global oil demand in the coming years, from 85 million barrels per day in 2008 to 105 million barrels per day in 2030.

Prior to the Copenhagen Climate Summit in December, the IEA called on all countries to exert efforts to curb climate deterioration by taking financial actions, such as developing environment-friendly transportation, housing and power plants and renovating biofuels.

Weeks before the global climate negotiation in Copenhagen, there are great differences between developed and developing countries on carbon emission goals and distribution of financial and technological responsibilities.

It is "time to act," the IEA underlined, saying that world leaders should not miss the opportunity to seal a post-Kyoto agreement.

The Kyoto Protocol, a worldwide agreement on climate issue, will expire in 2012.
