For a Sustainable Environmental, Renewable Energy is very important. Is renewable energy generation sustainable on its own? Here is a chart displaying How much concrete and steel is needed to build new wind turbines, measured by MWh?
Each wind turbine requires a lot of raw materials, energy to transport the materials and the labor to the deployment area, energy for the construction. We should make this whole process sustainable first. The wind turbines should be first installed near the steel, copper, aluminum and concrete manufacturing facilities. Electric operating drones, trucks and construction machinery should be utilized during the construction process. The money is poured into the personal use electric car manufacturing which is a luxury compared to the construction machinery which still heavily rely on carbon fuels. All the commercial use public buses, trucks, construction equipment should be 100% Electric First.
In my previous articles I proposed drone-based wind turbine construction. If we keep burning fuel to build wind farms, it would be hard to sustain the Renewable Energy movement in economical down turns.
