“…It is anticipated that throughout this time, market conditions and technological developments will have a substantial impact on the cost trajectory of renewable energy solutions. Historically, advances in materials science, manufacturing techniques, and economies of scale have caused a steady decrease in the cost of renewable energy components, most notably solar PV modules and wind turbines [43,44]. A continuation of this cost drop can be foreseen, making renewable energy more competitive with conventional energy sources, based on industry estimates and historical trends.…”
