In 2017, Taiwan announced that it would replace nuclear power, which accounts for approximately 4.43% of its total energy supply (or 8.30% of total electricity supply), with renewable energy by 2025. Thus developing reliable and stable renewable energy sources has become an urgent need. This study analyzes the portfolio of renewable energy technologies available to achieve such a goal. In doing such we consider potential of power generated from municipal solid waste (MSW), animal manure, energy crops, crop residues, wind power, and photovoltaic (PV) sources. The results show that up to an additional 5896 GWh (or million kWh) could be generated from recycled MSW, 3107 from animal manure, 6440 from energy crops and crop residues, 3685 from solar and 609 from wind power. Collectively, an increase in renewable energy production could expand to supply as much as 6.15% of current usage. Meanwhile, before replacing nuclear the use of fossil fuels can be reduced by up to 4.51%, increasing energy security, but a greater promotion on renewable energy development should be focused when nuclear power is phased out. We also discuss the cost of such a transition.

Biofuel production is of particular interest to Taiwan in the face of energy insecurity and climate change. Since climate-induced impacts such as changes in regional temperature and precipitation will influence crop yields, this study accommodates the estimated yield changes and subsequently develops a two-stage stochastic programming with recourse model to investigate the economic and environmental effects of biofuel production. The results indicate that the utilization of sweet potato, along with its by-products, can result in the maximum amount of ethanol production. At higher levels of gasoline and greenhouse gas (GHG) prices, 441.2 million liters of ethanol can be produced, of which 70 million liters come from utilization of by-products. In general, economic factors such as gasoline and GHG prices have larger impacts on biofuel production than yield changes. However, although biofuel production is relative stable in the face of crop yield change, a shift in cultivars and land-use pattern is likely to occur. We show that the net emission reduction is relatively low compared to Taiwan's total emission and the aggregate value of emission reduction merits more investigation. These concerns, as well as resource reallocation and policy reformulation are also discussed in detail.

The world faces unprecedented threats from climate change and increasing variability, which severely impacts human society and the natural environment. To reduce future climate change and ensure our economies can grow in a sustainable way, sustainable energy development is considered to be an effective approach. In this context, sustainable energy development involves augmenting our energy supplies and managing demands in a fashion that societal energy needs are met with a minimal effect on greenhouse gas emissions and a nominal resultant contribution to future climate change. In this Special Issue, research papers focus on the role of sustainable energy development (while addressing important dimensions of sustainability), which mandates an inter-disciplinary perspective in all articles. We collected 11 such papers that have analyzed a broad array of topics related to bioenergy, wind power, industrial innovation, and climate change mitigation. These papers show the varied application of renewable energy and climate change energy responses, while providing meaningful decision-making information and policy implications.

Taiwan imports more than 99% of her energy and suffers from climate change effects such as rising ocean level. Therefore, energy insecurity and GHG emissions offset are two serious problems facing Taiwan. This paper examines the possibilities for domestic bioenergy production in Taiwan utilizing set-aside land. Three bioenergy alternatives are examined: Pyrolysis-based bioelectricity, conventional bioelectricity and ethanol. We examine the comparative economics and choices among these alternatives under current Taiwanese agricultural system policies and also under altered energy and greenhouse gas/carbon prices. Biochar, produced from pyrolysis, is also investigated for different uses: whether it is best used as an energy source and/or a soil amendment. The study employs modified Taiwanese Agricultural Sector Model (TASM) to simulate the effects of the alternatives in the face of energy and greenhouse gases prices. Results show that ethanol production is chosen under current conditions but that this is replaced by pyrolysis-based bioelectricity when the GHG price is high. The results also indicate that Taiwan's energy security can be enhanced by domestic bioenergy production and up to1.59% of total GHG emissions can be offset.

Ecological land is like the “liver” of a city and is very useful to public health. Ecological land change is a spatially dynamic non-linear process under the interaction between natural and anthropogenic factors at different scales. In this study, by setting up natural development scenario, object orientation scenario and ecosystem priority scenario, a Cellular Automation (CA) model has been established to simulate the evolution pattern of ecological land in Beijing in the year 2020. Under the natural development scenario, most of ecological land will be replaced by construction land and crop land. But under the scenarios of object orientation and ecosystem priority, the ecological land area will increase, especially under the scenario of ecosystem priority. When considering the factors such as total area of ecological land, loss of key ecological land and spatial patterns of land use, the scenarios from priority to inferiority are ecosystem priority, object orientation and natural development, so future land management policies in Beijing should be focused on conversion of cropland to forest, wetland protection and prohibition of exploitation of natural protection zones, water source areas and forest parks to maintain the safety of the regional ecosystem.
