The Goal of Reducing Climate Change The OECD advisory on climate change (Green Grown Studies) states that a multi-pronged approach is required to reduce, stop, or reverse climate change. The critical stages in the energy lifecycle that need to be addressed include: Energy generation Transportation Conversion Storage Consumption Smart-grid technology Smart-homes Smart Manufacturing Smart circuits and computer chips Of all the green / renewable sources of power, nuclear fusion has the biggest potential impact. Nuclear fusion is the holy grail of renewable green energy sources and has the potential to drastically reduce CO2 output by replacing other fossil fuels such as coal-fired electricity plants. Other potential sources of renewable power such as solar, wind, geothermal, and hydro offer benefits over non-renewable power such as coal, and oil and gas, but none have the potential to output as much clean energy as realizing commercial of nuclear fusion.  However, a future global…
