 Pakistan is facing a serious energy supply problem due to lack of energy that results in a shortfall of power supply from 6–10 hours/day, especially outside the big cities. The energy demand is expected to increase in every sector such as industrial, agricultural, household and transport in the years ahead due to population growth, economic development and modern lifestyle. Agricultural sector plays a vital role in the country’s economy contributing around 20% share in GDP. At present the direct energy consumption in the agricultural sector is 2%. To avoid a worse situation in the future years renewable energy resource potential exploitation is needed. This requires also proper planning and implementation of energy policies. In this work present and future electrical energy consumption, demand and supply gap of the country is presented. A sustainable agricultural productive system has become a major priority to maintain food security for the increasing population. Both direct and indirect electrical and energy consumption has emerged in agrifood sector with farm machinery, production, packing and transport of fertilizers, food processing and transport, crop production, animal product production, poultry production, etc. In addition to this excel based model is developed to integrate the renewable energy into the agrifood – energy nexus supply chain and to fulfil the current and future energy demand of the sector.

This paper analysis on the international energy security situation and the energy consumption characteristics, and the proposals on international energy cooperation in China are put forward. With the sustained growth of energy consumption, fragile price system, intense conflict of energy politics, serious problems of energy and environment, the international energy security situation had been not optimistic. Due to the characteristics like large consumption, rapid growth, coal-based energy structure, low energy efficiency, high dependence on imports, serious environmental problems, increasing use of new energy and renewable energy, fruitful but troubled energy saving, required China to participate in international energy cooperation widely. In China international energy cooperation should be based on the principle of mutual benefit, technology sharing and dialogue & consultation, to ensure the conventional energy supply as fundamental goal, to develop and utilize new energy & renewable energy as direction, to establish energy-themed dialogue & communication as important pathway.

<p>Since conventional energy resources are major source of CO<sub>2</sub> emission, over reliance on fossil fuels has raised questions on environmental sustainability. On way to address these multi-faceted issues of conventional energy sources, the sustainability of energy and environment is through the green economy approach. As such, this paper aims to discuss the concept of green economy in relation with renewable energy. The interdependence of green economy and environmental quality as well as the compatibility of green economy approach with the notion of sustainable development are demonstrated in the paper. Green economy approach fulfils the methodological gaps that exist in the growth models. It is believed that the best economic tool to attain sustainable development goals is by integrating social, economic and environmental elements. Furthermore, energy is believed to be a significant player in determining the greenness of the economy and sustainability as it has economic and environmental value. In addition, this study illustrates the significance of biomass energy resource and CO<sub>2</sub> emissions from fossil fuel combustion. The illustration framework justifies that biomass is the determinant renewable energy source to be a proxy for renewable energy resources. Similarly, it justifies that CO<sub>2</sub> emission of energy sector is considerably significant to represent the CO<sub>2</sub> emissions of the atmosphere.</p>

Renewable energy resources (RESs) play an important role in the upgrading and transformation of the global energy structure. However, the question of how to improve the utilization efficiency of RESs and reduce greenhouse gas emissions is still a challenge. Combined heating and power (CHP) is one effective solution and has experienced rapid development. Nevertheless, with the large scale of RESs penetrating into the power system, CHP microgrid economic operation faces great challenges. This paper proposes a CHP microgrid system that contains renewable energy with considering economy, the environment, and system flexibility, and the ultimate goal is to minimize system operation cost and carbon dioxide emissions (CO2) cost. Due to the volatility of renewable energy output, the fuzzy C-means (FCM) and clustering comprehensive quality (CCQ) models were first introduced to generate clustering scenarios of the renewable energy output and evaluate the clustering results. In addition, for the sake of improving the flexibility and reliability of the CHP microgrid, this paper considers the battery and integrated energy demand response (IEDR). Moreover, the strategy choices of microgrid operators under the condition of grid-connected and islanded based on environment and interest aspects are also developed, which have rarely been involved in previous studies. Finally, this stochastic optimization problem is transformed into a mixed integer linear programming (MILP), which simplifies the calculation process, and the results show that the operation mode under different conditions will have a great impact on microgrid economic and environmental benefits.

The Us

We examine the relationship between renewable and non-renewable energy consumption and economic growth in the United States. While the regime-dependent Granger causality test results for the non-renewable energy consumption and economic growth suggest bi-directional causality in both regimes, we cannot validate any causality between renewable energy consumption and economic growth. The US meets its energy demand from non-renewable sources; as such, renewable energy consumption does not seem to affect economic growth. Given the efficiency and productivity of renewable energy investments, we conclude that it is worthwhile to consider renewable energy inputs to replace fossil fuels given potential benefits in terms of global warming and climate change concerns. In this regard, increasing the R&D investments in the renewable energy sectors, increases in productivity and profitability of renewable energy investments are likely to accrue benefits in the long run.

<p>A brief overview of present electricity demand, supply, projection of them and renewable energy generation and progress has been presented in this paper. Electricity is the major source of power for most of the country's economic activities. According to the Bangladesh Power Development Board in July 2018, 90 percent of the population had access to electricity. However per capita energy consumption in Bangladesh is considered low. The country has a very limited energy reserve; small amounts of oil, coal and countable natural gas reserves. The country suffers an internal energy struggle, as about 88% of the country’s power producing thermal plants are gas-based. To solve this problem, renewable energy is being used.</p>

Energy Needs

In Tunisia, the rural people have the smallest amounts of energy available. Their energy is used mainly for basic needs, and it often comes from noncommercial fuels, especially wood. Therefore, the rural areas are facing severe and interrelated problems of energy and environment. The environmental impacts of intensified production processes aggravate the degradation of ecologic systems. The analysis of the energy situation in rural areas of Tunisia has shown that a growing energy consumption can be expected over the entire spectrum of economic and social activities. To cope with this crisis, technologies for energy requirements should not only meet energy needs; they must also be geared to particular economic, social and environmental conditions. Technically efficient, decentralized systems for the utilization of new and renewable energy can help in this by meeting the demand for higher quality energy. This article attempts to propose precepts upon which a strategy can be formulated for a rational use of renewable energy in the rural areas.
