Effect of Agricultural Feedstock to Energy Conversion Rate on Bioenergy and GHG Emissions
Taiwan is eager to develop renewable energy because it is vulnerable to energy price distortion and ocean level rise. Previous studies show bioenergy technologies can be applied mutually, but pay little attention on feedstocks to energy conversion rate, which has potential influences on policy makin...
