This report assesses the feasibility of Scotland achieving 100% dependency on renewable energy sources by evaluating existing energy generation capacities, demand-supply dynamics, and utilizing the EnergyPlan software for scenario building. The analysis considers various renewable sources such as hydro, wind, solar, and wave energy, examining their potential to meet Scotland's energy needs while phasing out fossil fuels. The report also explores the costs associated with building pumped hydro storage (PHS) and critically analyzes the derived scenarios, highlighting the challenges and opportunities in transitioning to a fully renewable energy system, emphasizing the need for significant investments, policy reforms, and further research into untapped renewable sources to meet ambitious energy targets by 2020 and beyond.
