Abstract: This paper presents a review about conventional and renewable energy scenario of the county in quantitative terms of supply, generation and exploitation of available resources. In this energy scenario, the renewable energy share is in the range of a fraction of a percentage compared to total conventional energy supplies, so depicting it as a sector of least significance for government. Main emphasis in this paper has been given on presentation of data about renewable energy (RE) installations in the country, on-going activities, development projects, RE planning and achievements of public sector RE institutions and organizations. At the end some suggestions are given for effective planning and exploitation of RE resources and use of technologies. These suggestions are not only useful for Pakistan but also are equally important for the third world countries to enhance appreciably RE contribution in their total energy supplies of their country.

In terms of land use competition, bioenergy is often subject to controversial discussions. This paper presents a study, which addresses the scope of geographic discrete biomass growth, optimal bio-energy plant locations, and related biomass supply areas. In a first step, annual biomass growth is calculated with the BETHY/DLR model on a spatial resolution of 1 km 2 . In a second step, the ASECO model is utilized to identify optimal plant locations with related biomass supply areas, determined by biomass growth rates and available road infrastructure. The case study is carried out for Pakistan. Scenarios have been investigated on district level, with a special focus on total supply areas for single power plants at identified locations, as well as supply area deviations over the years due to varying biomass growth rates. Achieved results are relevant for the political debate on an optimal bioenergy strategy for Pakistan. [ABSTRACT FROM AUTHOR]
