Conference Paper
According to the World Bank report Southeast Asian countries produced 5.6% of total global GHG emissions in 2018. The four countries i.e., Indonesia, Thailand, Malaysia and Vietnam contributed more than 80% of CO2 emissions. With one of the fastest growing economy the region’s energy related GHG emissions are expected to rise by 34% to 147% between...
Conference Paper
Despite numerous energy system optimization models for long-term planning on a national level, the plausibility assessment of suggested pathways is seldom involved taking into consideration: 1) the impact of existing capacity stocks on the future energy system; 2) self-corrective functionality if the pathway diverges from the projected ones a poste...

Article
With the introduction of its energy concept in 2010, the German government set ambitious targets for the country's energy and climate policy. According to this concept, greenhouse gas (GHG) emissions will have to be reduced by 80% by 2050, as compared to 1990 levels, and renewables will have to supply 80% of all electricity needs by the same year....

Article
Ambitious decarbonization targets, technology-specific policies, and computational developments led to increases in the complexity and diversity of energy system models. The lack of transparency and standardization, however, renders the assessment of model suitability for specific policy questions difficult. Therefore, this paper systematically ass...
Article
At the 2015 Paris Climate Summit, all parties decided to limit global warming to at least 2 ° C, and preferably to 1.5 ° C in order to reduce the impact of climate change. The current policy target to reduce GHG emissions in Germany by 80–95% by 2050 stabilizes global warming at 2 ° C. For the more ambitious limitation of 1.5 ° C, these targets nee...

Conference Paper
European Union has set ambitious goals to reduce the GHG emissions by 20% until 2020 and 80% until 2050 compared to 1990 level for environmental and economic sustainability. Because of geopolitical reason, Central Europe can play a crucial role in achieving these targets. This work mainly focuses on Central Europe, namely, Germany, Austria, Switzer...
Article
Global climate change, energy consumption pattern and economic growth are major issues nowadays for the developing world like India. Due to global threat of climate change, Indian economy experience big challenges to maintain its high growth rate if switched to the clean energy generation for environmental sustainability. In this situation, there i...

The German electricity sector is in a period of transition, spurred by the German government's endeavor to maintain a sustainable, secure, climate-friendly and affordable energy supply system. The most important aspects of this Energiwende are the phase out of nuclear energy, promotion of renewable energy technologies, and reduction of greenhouse g...
Article
The Indian power sector is experiencing a lot of pressure to supply sustainable electricity at affordable cost due to heavy demand especially in the summer peak season. Most of India's electricity is produced by fossil fueled power plants, which are the source of CO2 emissions. In this case, renewable energy sources play a vital role in securing su...
Article
Due to fast rising energy demand, Southeast Asia has become a larger energy consumer and bigger player in global energy markets. Energy security and environmental emissions reduction have become higher priorities to ensure energy supply at affordable costs, for continued economic growth and development. To address these issues renewable energy play...

Global warming is a universal problem nowadays. The recent United Nations Climate Change Conference in Copenhagen was partially successful because all participating countries realised the damages caused by greenhouse gas (GHG) emissions and promise to mitigate in the future course of time. India has also promised to reduce 20% to 25% of these emiss...
Article
Sensitivity analysis is a technique that evaluates the model response to changes in input assumptions. Due to uncertain prices of primary fuels in the world market, Government regulations for sustainability and various other technical parameters there is a need to analyze the techno-economic parameters which play an important role in policy formula...
Article
India is facing great challenges in its economic development due to the impact on climate change. Energy is the important driver of economy. At present Indian energy sector is dominated by fossil fuel. Due to international pressure for green house gas reduction in atmosphere there is a need of clean energy supply for energy security and sustainable...
Article
Present trends of electrical energy supply and demand are not sustainable because of the huge gap between demand and supply in foreseeable future in India. The path towards sustainability is exploitation of energy conservation and aggressive use of renewable energy systems. Potential of renewable energy technologies that can be effectively harnesse...
Article
Due to the growing energy needs along with increasing concerns towards control of greenhouse gas emissions, most developing countries are under pressure to find alternative methods for energy conversion and policies to make these technologies economically viable. Most of the energy is produced from fossil fuel in India which is not a sustainable so...
Article
This paper deals with MARKAL allocations for various energy sources, in India, for Business As Usual (BAU) scenario and for the case of exploitation of energy saving potential in various sectors of economy. In the BAU scenario, the electrical energy requirement will raise up to 5000 bKwh units per year or 752 GW of installed capacity with major con...
Article
The present gap between demand and supply of electricity in India may grow up to 70% in the year 2045, if corrective measures are not taken immediately. The projected situation for the growing Indian economy needs to be tackled by measures to reduce demand as well as to explore additional energy efficient technologies. This paper examines the effec...
Article
The present paper deals with an econometric model to forecast future electricity requirements for various sectors of Indian economy. Following the analysis of time series of sectoral GDPs, number of consumers in various sectors and price indices of electricity, a logarithmic linear regression model has been developed to forecast long-term demand of...
