Energy analysis and environmental impacts of microalgal biodiesel in China

Yanfen, Liao; Zehao, Huang; Xiaoqian, Ma - In: Energy Policy 45 (2012) C, pp. 142-151

The entire life cycle of biodiesel produced by microalgal biomasses was evaluated using the method of life cycle …, esterification, biodiesel transportation and biodiesel combustion. The investigation results show that the fossil energy requirement … for the biodiesel production is 0.74MJ/MJ biodiesel, indicating that 1MJ of biodiesel requires an input of 0.74MJ of …

Subsidy modes, waste cooking oil and biofuel: Policy effectiveness and sustainable supply chains in China

Zhang, Huiming; Li, Lianshui; Zhou, Peng; Hou, Jianmin; … - In: Energy Policy 65 (2014) C, pp. 270-274

Many countries are concerned with the waste-to-energy for economic development and societal welfare. This paper constructs a dynamic game model that, for the first time compares the incentive effects of four common subsidy modes on waste cooking oil supply for biofuel refining and sales of waste...

Biofuels and food security: Micro-evidence from Ethiopia

Negash, Martha; Swinnen, Johan F.M. - In: Energy Policy 61 (2013) C, pp. 963-976

There is considerable controversy about the impact of biofuels on food security in developing countries. A major concern is that biofuels reduce food security by increasing food prices. In this paper we use survey evidence to assess the impact of castor production on poor and food insecure rural...

The feasibility and implications for conventional liquid fossil fuel of the Indonesian biofuel target in 2025

Rahmadi, Arie; Aye, Lu; Moore, Graham - In: Energy Policy 61 (2013) C, pp. 12-21

This paper identifies conventional liquid fossil fuels that can be replaced or blended with biofuel and quantifies the biofuels required to meet the Indonesian biofuel target of at least 5% of the total primary energy mix in 2025. The analysis was conducted using the Long range Energy...

Rethinking improved cookstove diffusion programs: A case study of social perceptions and cooking choices in rural Guatemala

Bielecki, Christopher; Wingenbach, Gary - In: Energy Policy 66 (2014) C, pp. 350-358

Promoters of improved cookstoves (ICSs) argue they provide the “triple benefits” of improving health outcomes, preserving local ecosystems, and reducing greenhouse gas emissions. The majority of ICS research reveals a strong pro-diffusion bias toward proving these benefits. Few studies have...

The role of sustainability and life cycle thinking in U.S. biofuels policies

Soratana, Kullapa; Harden, Cheyenne L.; Zaimes, George G.; … - In: Energy Policy 75 (2014) C, pp. 316-326

A comprehensive review of the U.S. federal biofuel-related policies, from 1955 to 2012, was conducted to examine the progression of life cycle thinking within the policies. Over 1300 past and present federal and state biofuel laws and incentives were analyzed to identify the establishment of...

Implications of local lifecycle analyses and low carbon fuel standard design on gasohol transportation fuels

Boies, Adam M.; McFarlane, Dane; Taff, Steven; Watts, … - In: Energy Policy 39 (2011) 11, pp. 7191-7201

State and regional policies, such as low carbon fuel standards (LCFSs), increasingly mandate that transportation fuels be examined according to their greenhouse gas (GHG) emissions. We investigate whether such policies benefit from determining fuel carbon intensities (FCIs) locally to account...

Nonrenewable energy cost of corn-ethanol in China

Yang, Q.; Chen, G.Q. - In: Energy Policy 41 (2012) C, pp. 340-347

Nonrenewable energy cost is accounted for the believed renewable biofuel of corn-ethanol in China. By a process-based energy analysis, nonrenewable energy cost in the corn-ethanol production process incorporating agricultural crop production, industrial conversion and wastewater treatment is...
