The globe is currently facing a climate emergency and we need to act now before it is too late. The reason we are in a climate and energy crisis is because the world has relied on fossil fuels for export, instead of focusing on renewable energy and energy efficiency. An alternative solution to the climate crisis is electrification. Electrification is a process of heating with heat pumps that has advantages in reducing the need for oil in electrical vehicles, and reducing the usage of natural gas. Renewable energy and energy efficiency works hand in hand with electrification as the usage of coal and natural gas is reduced as well resultant climate destabilisation and carbon emissions. To decrease costs of equipment and increase innovation, an effective solution that has proven to be effective is a free and open source hardware design, which is pertaining to a wide range of industries. This process can accelerate the implementation of strategies and policies regarding practical implementation to reduce the usage of oil, gas and coal. The article by Pearce visually shows how the power of open source will be explained and to show how it can improve the performance and decrease the costs of decarbonization technologies.”
