UN Chief Ban Ki-moon on Wednesday said that the world needs a "clean energy revolution" to to meet growing energy demands and cut greenhouse gas emission.
At the launch of report on energy and climate change, Ban underlined the need to transform the "global energy system" to grow in a clean way.
The new report prepared by Ban's Advisory Group on Energy and Climate Change calls for a transition to a new energy pathway that will provide universal access to modern energy sources by 2030.
"The decisions we make today on energy will have a profound impact on the global climate, on sustainable development, on economic growth, and global security," Ban said.
"We need a clean energy revolution -- in developing countries, where demand is rising rapidly, and in the developed world, in order to cut greenhouse gas emission," he added.
Ban pointed out that some 1.6 billion people lack access to electricity and two to three billion people still rely on traditional energy, which affects their lungs and keeps them trapped in poverty.
"We cannot achieve the Millennium Development Goals without providing access to affordable modern energy," Ban said.
"Without electricity you cannot do anything in this world."
"Access to energy needs to be expanded in the cleanest, most efficient way possible," Ban said.
"These are ambitious goals, but I think they are achievable," he added.
The president of the UN Foundation, Timothy Wirth emphasized the need to "bring the private sector into the discussion of energy access."
"This is what it is going to take to make reality out of the report."
Another advisor and CEO of Statoil group, Helge Lund underlined the need for a robust framework and regulatory regimes to spur investments.
"A stable and attractive investment framework is essential to incentivise long-term investments and mobilise private capital."
"We need a system that brings emissions down in a cost-efficient and non-discriminatory way," he added.
At the end of the report, the Advisory Group has called for a 40 per cent reduction in global energy intensity by 2030 with greater use of renewable energy and other green technologies.
