Falling number of patents for renewable energy products risks governments missing carbon reduction targets
The number of patents for renewable energy products filed worldwide has fallen by 42% over the last three years,which could suggest that global investment in green energy is stalling.
Research from commercial law firm EMW shows that 20,655 green energy patents were filed globally in 2014, for solar power, wind energy, biofuels and waste-generated energy – down from 35,590 in 2012.
