We already knew about Nissan's installation of wind turbines in its Sunderland plant and solar panels in its Barcelona plant. This sort of greening up is, indeed, a good idea, an idea which Toyota is now copying for its engine plant in Flintshire, Wales.
Flintshire County Council is likely to approve Toyota's installation of a temporary wind monitoring mast. The 60-meter mast, at the southern end of the plant site, would monitor wind speeds at various heights over 12 months, to determine the viability of wind power.
The plant already uses osmosis-purified rainwater but saving CO2 with wind turbines is surely a step ahead: casting, machining and smelting use a lot of energy.
