Wales will adopt "cleaner, more efficient energy production" according to a Welsh Assembly Government scheme launched on Monday.
The assembly government said it is committed to clean energy
The Energy Route Map includes policies for Wales on energy supply and sets out dates for energy policy objectives to be met.
It will be launched for consultation on Monday by Economic Development Minister Andrew Davies.
But environmental groups have called for more action on global warming.
The assembly government said its route map balances the need to keep Wales' economy competitive while maintaining high environmental standards.
One of the policies the document is expected to contain is the provision of new planning guidance for onshore windfarms.
However, no mention is likely to be made over nuclear power.

Environmental groups such as the World Wildlife Fund have criticised politicians, including First Minister Rhodri Morgan, for being complacent about global warming.
Ahead of the launch, Mr Davies said: "We are already playing a significant role in pursuing clean energy and renewable energy generation in Wales.
"However, we have the capacity and the duty to do more.
"We need to facilitate many more clean energy projects (while) continuing to raise the profile of energy efficiency.
"The pursuit of a clean and high-efficiency energy policy through renewable energies, cleaner fossil fuel technologies and increased focus on energy efficiency offer significant economic development and environmental opportunities for Wales."
Mr Davies will launch the route map at Baglan Bay power station near Port Talbot, a £300m plant claimed to be among the most technologically-advanced and efficient when it opened in 2003.
