       The RES Group has a long history in wind technology development
       RES Americas takes projects from conception - leasing land, acquiring transmission rights and setting
        up Power Contracts with Utilities
       RES Americas is currently constructing approximately 1,400 MW, representing more than 30% of the
        wind capacity currently under construction in the U.S. and will have constructed approximately
        3,500MW by the end of 2008.

Wind Power Industry Overview

Renewable energy is                 Between 2007 and 2030, electricity demand in the U.S. and Canada is
expected to capture a                expected to increase approximately 30%
significant portion of the
                                    Significant portion will be met with renewables
electricity sector
                                    Wind expected to represent 7% of U.S. capacity by 2015
Wind energy is the future of        Cumulative capacity of 57,000 MW by 2015
renewable power generation
                                    RES currently has over 600 MW in various stages of development in Kansas

                                    PTCs
Wind energy incentives              Accelerated tax depreciation
                                    State / provincial policies and wind energy incentives
                                     − Renewable Portfolio Standards (“RPS”)

Greenhouse gas                      Focus on greenhouse gas emissions in both the U.S. and Canada has further
considerations                       prompted the growth in renewable generation

                                    Through 2012, natural gas prices are forecast to remain in the $8-$12/mmbtu
Increasing cost of traditional       range, keeping wind cost-competitive with gas-fired electricity generation in
fuels                                many state electricity markets

Emerging Renewables

   RES is using wind power
    expertise to develop and
    construct projects that
    generate power using solar
    thermal, solar PV, and biomass

   Also interested in energy
    storage, though this is still a   Solar PV can generate power almost anywhere – but it’s still expensive
    developing field.

   Focused on utility-scale, grid-
    connected projects.

   RES is leveraging existing land
    positions, interconnection
    agreements, and relationships
    with utilities
                                          Solar thermal is less expensive –
                                          but requires the direct sunlight found in the Southwest US
