The International Panel on Climate Change IPCC suggests that by the end of the year 2050, the overall GHG emission has to be reduced by 50-80 of the emission level of year 2000. At the same time to meet the energy demand worldwide the energy supplies must double by 2050 World Energy Council. This research proposed a methodology to mitigate the climate change problems and to reduce the reliance on non-renewable energy sources through an integrated modeling approach.
<br>An integrated modeling tool was used in this study to 1 track energy consumption, production, and resource extraction, 2 track greenhouse gases emissions and 3 analyze emissions for local and regional air pollutions.
<br>The model was used in this study for short and long term energy and GHG emissions reduction analysis for the state of Florida. The integrated modeling methodology will help to evaluate the alternative energy scenarios and examine emissions-reduction strategies.
<br>The mitigation scenarios have been designed to describe the future energy strategies. They consist of various demand and supply side scenarios.
<br>One of the GHG mitigation scenarios is crafted by taking into account the available renewable resources potential for power generation in the state of Florida to compare and analyze the GHG reduction measure against “Business As Usual” and “Florida State Policy” scenario.
<br>Two more “integrated” scenarios, “Electrification” and “Efficiency and Lifestyle” are crafted through combination of various mitigation scenarios to assess the cumulative impact of the reduction measures such as technological changes and energy efficiency and conservation.

The objective of the research is to develop various green-house gas (GHG) mitigations scenarios in the energy demand and supply sectors for state of Florida through energy and environment modeling tool called LEAP (Long Range Energy Alternative Planning System Model) for 2010-2050. The GHG mitigation scenarios consist of various demand and supply side scenarios. One of the GHG mitigation scenarios is crafted by taking into account the available renewable resources potential for power generation in the state of Florida and then the comparison has been made for transformation sector and corresponding GHG emissions through this newly developed mitigation scenario versus Business As Usual and Florida State Policy scenario. Moreover two master mitigation scenarios (Electrification and Efficiency and Lifestyle) were crafted through combination of certain GHG mitigation scenarios. The energy demand and GHG emissions assessment is performed for both master mitigation scenarios versus business As Usual scenario for 2010 – 2050.

The goal of this Thesis is to demonstrate, through experimentation, that
ocean waves have a positive effect on the performance of an offshore wind
turbine. A scale model wind turbine was placed into a wave tank that was
completely covered and fitted with a variable speed fan to create different wind
and wave conditions for testing. Through testing, different power coefficient vs.
tip speed ratio graphs were created and a change in power coefficient was
observed between steady operating conditions and operating conditions with
waves. The results show a promising increase in power production for offshore
wind turbines when allowed to operate with the induced motion caused by the
amplitude and frequency of water waves created.
