Introduction  Energy resource in Guangdong is scanty. Energy self-sufficiency ratio is low. And cost of energy is very high. With the increase of economic development and change of industrial structure, energy and source development will face new situation and challenge. The purpose of this article is to strengthen energy supply support capability, reduce energy cost, increase the rate of non-fossil source and optimize source structure.

  Method  This paper analyzed the present position of energy development, and forecasted the need of energy and electric power in the future with the scientific and reasonable methods. The method of calculation of energy and power balance was applied. We confirmed the lack of energy and power. Also this paper focused on the way and position of energy and source development strategy with the characters of different energy and source varieties.

  Result  The result shows that in long-term period Guangdong energy development should ensure supplies and adjust structure, and in short-term period it should control total and promote clean development. Four source modes in 2030 are proposed, which are low-carbon mode, ecnomic mode, high flexible mode and comprehensive mode. All modes could satisfy the lack of energy and power. And fuel supply capability, environmental protection space and site resource could support the need of source development. By comparison this paper recommends the comprehensive mode.

  Conclusion  The research is the reference for Guangdong government.
